Teaching hospitals do not provide better care than non-teaching hospitals.

Patient Outcomes with Teaching Versus Nonteaching Healthcare: A Systematic Review

Background  Extensive debate exists in the healthcare community over whether outcomes of medical care at teaching hospitals and other healthcare units are better or worse than those at the respective nonteaching ones. Thus, our goal was to systematically evaluate the evidence pertaining to this question. Methods and Findings  We reviewed all studies that compared teaching versus nonteaching healthcare structures for mortality or any other patient outcome, regardless of health condition. Studies were retrieved from PubMed, contact with experts, and literature cross-referencing. Data were extracted on setting, patients, data sources, author affiliations, definition of compared groups, types of diagnoses considered, adjusting covariates, and estimates of effect for mortality and for each other outcome. Overall, 132 eligible studies were identified, including 93 on mortality and 61 on other eligible outcomes (22 addressed both). Synthesis of the available adjusted estimates on mortality yielded a summary relative risk of 0.96 (95% confidence interval [CI], 0.93–1.00) for teaching versus nonteaching healthcare structures and 1.04 (95% CI, 0.99–1.10) for minor teaching versus nonteaching ones. There was considerable heterogeneity between studies (I2 = 72% for the main analysis). Results were similar in studies using clinical and those using administrative databases. No differences were seen in the 14 studies fully adjusting for volume/experience, severity, and comorbidity (relative risk 1.01). Smaller studies did not differ in their results from larger studies. Differences were seen for some diagnoses (e.g., significantly better survival for breast cancer and cerebrovascular accidents in teaching hospitals and significantly better survival from cholecystectomy in nonteaching hospitals), but these were small in magnitude. Other outcomes were diverse, but typically teaching healthcare structures did not do better than nonteaching ones. Conclusions  The available data are limited by their nonrandomized design, but overall they do not suggest that a healthcare facility's teaching status on its own markedly improves or worsens patient outcomes. Differences for specific diseases cannot be excluded, but are likely to be small.

Developing primary palliative care.

Although 65% of people with cancer want to die at home, only about 30% are successful in doing so.1,2 A government committed to choice for patients must improve this figure.3 Developing palliative care services in primary care is essential for realising the expectations of dying people. Such services could also offer important opportunities for extending supportive humane care at an earlier stage, and to people not only with cancer but with chronic obstructive pulmonary disease, motor neurone disease, and cardiac failure, for example, who also often have palliative care needs. Primary care professionals have the potential and ability to provide end of life care for most patients, given adequate training, resources, and, when needed, specialist advice.4,5 They share common values with palliative care specialists—holistic, patient centred care, delivered in the context of families and friends.6 However, until recently, apart from Macmillan general practitioners and nurse facilitators, few comprehensive workforce initiatives have been undertaken in primary care that focus on end of life care. Many cancer patients and their carers experience existential distress long before they die.7 Recognising and alleviating such suffering is important, but it often goes unrecognised or is overlooked by services focusing on the terminal phase of illnesses. Primary care teams may know patients over long periods of time. They can readily identify patients from cancer and chronic disease registers who might benefit from an early palliative care approach. Such patients could be identified by clinicians asking one simple question of themselves: “Would I be surprised if my patient were to die in the next 12 months?”8 By identifying such patients proactively we could deliver, simultaneously, active treatment and patient centred supportive care, through a team with whom many patients have a valued long term relationship. Palliative care services need to be extended to patients with non-malignant conditions who have comparable concerns to and in some cases even greater unmet needs than cancer patients.9 Progress by palliative medicine specialists is hampered by issues such as uncertainty about the most effective models of care, lack of non-cancer expertise, and concerns about pressure on specialist services. General practitioners and community nurses can lead the way in providing a palliative care approach for patients with terminal organ failure illness. The first step in such an approach is for the goals of care to be discussed and agreed. Management plans are adjusted accordingly. Effective control of symptoms and maintaining quality of life are prioritised. In the light of these important opportunities it is regrettable that the new general medical services contract has not prioritised palliative care. By day, other developments to achieve the quality indicators are taking precedence. By night and at weekends, the new unscheduled care services (which are responsible for providing care for 75% of the hours in the week) are even less well configured than previous out of hours provision to facilitate dying at home. Such services specialise in dealing with acute emergencies and, as such, often struggle to meet the medical, nursing, and social care needs of dying people and their families. These changes will greatly affect care for dying people and may increase the number of hospital admissions. However, one important initiative is gaining momentum within primary care. The Gold Standards Framework is a resource for organising proactive palliative care in the community and is supported by funding from the Cancer Services Collaborative, Macmillan Cancer Relief, and the National Lottery.10 The framework provides a detailed guide to providing holistic, patient centred care and thereby facilitates effective care in the community. Other recently initiated mechanisms for developing primary palliative care include the training of general practitioners with a special interest in palliative care and the new end of life initiative in England to improve palliative care provision by generalists and to share examples of good practice. To support such developments it is essential that primary palliative care is supported by an adequate academic base.11 This is admittedly a challenging arena in which to undertake research, but progress has been made in recent years in developing conceptual models and research architectures for studying end of life issues. Now we need to build on this work to ensure that the understanding and insights gleaned can be translated into effective interventions. Every person with a progressive illness has a right to palliative care.12 Patients desire a reassuring professional presence in the face of death. General practitioners and community nurses are trusted by patients and are in a position to provide effective, equitable, and accessible palliative care. This will happen only if they have adequate time and resources and work in a system that encourages such care. Patients who receive holistic support in the community may be less likely to require expensive admission to hospital and often futile treatments at the end of their lives.

Long-term survival, quality of life, and quality-adjusted life-years among critically ill elderly patients.

OBJECTIVES To assess mortality, quality of life (QOL), and quality-adjusted life-years (QALYs) for critically ill elderly patients. DESIGN Cross-sectional survey. SETTING A ten-bed medical-surgical intensive care unit (ICU) in a tertiary care university hospital. PATIENTS The study group included 882 elderly patients (> or =65 yrs of age) and 1,827 controls (<65 yrs of age) treated during the period of 1995 to 2000. INTERVENTION None. MEASUREMENTS AND MAIN RESULTS Mortality was assessed during the ICU and hospital stays, and 12, 24, and 36 months after ICU discharge. The cumulative 3-yr mortality rate among the elderly (57%) was higher (p < .05) than that among the controls (40%). The majority (66%) of the elderly nonsurvivors died within 1 month after intensive care discharge. All elderly patients with day-1 Sequential Organ Failure (SOFA) scores >15 died during the ICU stay. QOL was assessed with EQ-5D and RAND-36 measures from 10 months to 7 yrs after discharge. The majority (88%) of the elderly survivors assessed their present health state as good or satisfactory; 66% found it to be similar or better than 12 months earlier, and 48% similar or better than their preadmission state. QOL measures by RAND-36 revealed that aging decreased their competencies most in physical functioning, physical role limitations, and vitality, but the elderly had better values in mental health than the controls. However, QALYs of the elderly respondents were 21% to 35% lower than the mean QALY minus 2 sd units of the age- and gender-adjusted general population. CONCLUSIONS High age alone is not a valid reason to refuse intensive care, but the benefits perceived by intensive care seem to decrease with aging, if reflected as QALYs. However, 97% of the elderly survivors lived at home and 88% of them considered their QOL satisfactory or good after hospital discharge. Therefore, more reliable information on the outcome for the elderly is clearly needed.

Home birth and barriers to referring women with obstetric complications to hospitals: a mixed-methods study in Zahedan, southeastern Iran

BACKGROUND One factor that contributes to high maternal mortality in developing countries is the delayed use of Emergency Obstetric-Care (EmOC) facilities. The objective of this study was to determine the factors that hinder midwives and parturient women from using hospitals when complications occur during home birth in Sistan and Baluchestan province, Iran, where 23% of all deliveries take place in non- hospital settings. METHODS In the study and data management, a mixed-methods approach was used. In the quantitative phase, we compared the existing health-sector data with World Health Organization (WHO) standards for the availability and use of EmOC services. The qualitative phase included collection and analysis of interviews with midwives and traditional birth attendants and twenty-one in-depth interviews with mothers. The data collected in this phase were managed according to the principles of qualitative data analysis. RESULTS The findings demonstrate that three distinct factors lead to indecisiveness and delay in the use of EmOC by the midwives and mothers studied. Socio-cultural and familial reasons compel some women to choose to give birth at home and to hesitate seeking professional emergency care for delivery complications. Apprehension about being insulted by physicians, the necessity of protecting their professional integrity in front of patients and an inability to persuade their patients lead to an over-insistence by midwives on completing deliveries at the mothers' homes and a reluctance to refer their patients to hospitals. The low quality and expense of EmOC and the mothers' lack of health insurance also contribute to delays in referral. CONCLUSIONS Women who choose to give birth at home accept the risk that complications may arise. Training midwives and persuading mothers and significant others who make decisions about the value of referring women to hospitals at the onset of life-threatening complications are central factors to increasing the use of available hospitals. The hospitals must be safe, comfortable and attractive environments for parturition and should give appropriate consideration to the ethical and cultural concerns of the women. Appropriate management of financial and insurance-related issues can help midwives and mothers make a rational decision when complications arise.

Integration of mental health into primary healthcare in low-income countries: avoiding medicalization.

Since 2008 the World Health Organization (WHO), through its mental health Gap Action Programme, has attempted to revitalize efforts to integrate mental health into non-specialized (e.g. primary) healthcare. While this has led to renewed interest in this potential method of mental health service delivery, it has also prompted criticism. Some concerns raised are that it would contribute to the medicalization of social and psychological problems, and narrowly focus on primary care without sufficient attention given to strengthening other levels of the healthcare system, notably community-based care and care on district levels. This paper discusses seven elements that may be critical to preventing inadvertently contributing to increasing a narrow biomedical approach to mental healthcare when integrating mental health into non-specialized healthcare: (1) using task shifting approaches within a system of stepped care, (2) ensuring primary mental healthcare also includes brief psychotherapeutic interventions, (3) promote community-based recovery-oriented interventions for people with disabling chronic mental disorders, (4) conceptualizing training as a continuous process of strengthening clinical competencies through supervision, (5) engaging communities as partners in psychosocial interventions, (6) embedding shifts to primary mental healthcare within wider health policy reforms, and (7) promoting inter-sectoral approaches to address social determinants of mental health.

"We charge them; otherwise we cannot run the hospital" front line workers, clients and health financing policy implementation gaps in Ghana.

OBJECTIVES This paper examines policy implementation gaps of user fees plus exemptions and health insurance in providing financial access to primary clinical care for children under five in Ghana. METHODS Methods included analysis of routine data, focus group discussions, in-depth interviews, and administration of a structured questionnaire. RESULTS Providers modified exemptions policy implementation arrangements, sometimes giving partial or no exemptions. Clients who knew or suspected exemption entitlements failed to request them because of fear of negative reactions from providers. Providers attributed their modification of implementation arrangements and negative reactions to the threat posed to the financial viability of their institutions by reimbursement uncertainty and delays. At the time of the study insurance coverage was low and frontline workers were not noticeably modifying implementation arrangements. However, the underlying goal conflicts, resource scarcity, conditions of work and relationships between frontline workers and clients that fueled the exemptions policy implementation gaps were unchanged. The potential for the health insurance policy to stumble over implementation gaps as happened with the exemptions policy therefore remained. CONCLUSIONS Policies that do not take into account the incentives for frontline worker adherence and align them better with policy objectives may experience implementation gaps.

Why do general practitioners prescribe antibiotics for upper respiratory tract infections to meet patient expectations: a mixed methods study

OBJECTIVES To describe the role patient expectations play in general practitioners (GPs) antibiotic prescribing for upper respiratory tract infections (URTI). METHODS Concurrent explanatory mixed methods approach using a cross-sectional survey and semistructured interviews. SETTINGS Primary care GPs in Australia. PARTICIPANTS 584 GPs (response rate of 23.6%) completed the cross-sectional survey. 32 GPs were interviewed individually. OUTCOME MEASURE Prescribing of antibiotics for URTI. RESULTS More than half the GP respondents to the survey in Australia self-reported that they would prescribe antibiotics for an URTI to meet patient expectations. Our qualitative findings suggest that 'patient expectations' may be the main reason given for inappropriate prescribing, but it is an all-encompassing phrase that includes other reasons. These include limited time, poor doctor-patient communication and diagnostic uncertainty. We have identified three role archetypes to explain the behaviour of GPs in reference to antibiotic prescribing for URTIs. The main themes emerging from the qualitative component was that many GPs did not think that antibiotic prescribing in primary care was responsible for the development of antibiotic resistance nor that their individual prescribing would make any difference in light of other bigger issues like hospital prescribing or veterinary use. For them, there were negligible negative consequences from their inappropriate prescribing. CONCLUSIONS There is a need to increase awareness of the scope and magnitude of antibiotic resistance and the role primary care prescribing plays, and of the contribution of individual prescribing decisions to the problem of antibiotic resistance.

Husbands' involvement in delivery care utilization in rural Bangladesh: A qualitative study

BACKGROUND A primary cause of high maternal mortality in Bangladesh is lack of access to professional delivery care. Examining the role of the family, particularly the husband, during pregnancy and childbirth is important to understanding women's access to and utilization of professional maternal health services that can prevent maternal mortality. This qualitative study examines husbands' involvement during childbirth and professional delivery care utilization in a rural sub-district of Netrokona district, Bangladesh. METHODS Using purposive sampling, ten households utilizing a skilled attendant during the birth of the youngest child were selected and matched with ten households utilizing an untrained traditional birth attendant, or dhatri. Households were selected based on a set of inclusion criteria, such as approximate household income, ethnicity, and distance to the nearest hospital. Twenty semi-structured interviews were conducted in Bangla with husbands in these households in June 2010. Interviews were transcribed, translated into English, and analyzed using NVivo 9.0. RESULTS By purposefully selecting households that differed on the type of provider utilized during delivery, common themes--high costs, poor transportation, and long distances to health facilities--were eliminated as sufficient barriers to the utilization of professional delivery care. Divergent themes, namely husbands' social support and perceived social norms, were identified as underlying factors associated with delivery care utilization. We found that husbands whose wives utilized professional delivery care provided emotional, instrumental and informational support to their wives during delivery and believed that medical intervention was necessary. By contrast, husbands whose wives utilized an untrained dhatri at home were uninvolved during delivery and believed childbirth should take place at home according to local traditions. CONCLUSIONS This study provides novel evidence about male involvement during childbirth in rural Bangladesh. These findings have important implications for program planners, who should pursue culturally sensitive ways to involve husbands in maternal health interventions and assess the effectiveness of education strategies targeted at husbands.

Place of care in advanced cancer: a qualitative systematic literature review of patient preferences.

BACKGROUND It is commonly written that more patients wish to die at home than currently achieve this. However, the evidence for preferences for place of terminal care and death has not been systematically reviewed. AIM To carry out a systematic literature review of the preferences for place of care and death among advanced cancer patients. METHOD Studies were identified using systematic database searches of MEDLINE (1966-1999), PsychLit (1974-1999), and Bath Information Data Service (BIDS) (1981-1999). Studies were assessed and data extracted and synthesises following the NHS Centre for Reviews and Dissemination guidelines, grading studies according to design and rigor of methods. Studies of preferences in the general population and of groups including cancer patients and/or their caregivers were included. RESULTS Eighteen studies determining preferences in either the general population or groups including cancer patients were identified. Views were obtained prospectively and retrospectively from patients, the general population, families, and professionals. Respondents indicated preferences for home death (range 49%-100%), except one study of patients in the care of a continuing care team in London where only 25%-29% of patients wanted a home death, and inpatient hospice was the most favored option. However, the response rate of this study was not known. Among the general public there was a higher preference for inpatient hospice care among in people with recent experience of a close friend or relative's death or dying. Where the views of patients, families, and professionals were compared, all respondents broadly agreed although patients expressed the strongest home preferences. Only 2 of the studies provided longitudinal data, and 9 of the 18 had major deficits in design or reporting, such as poor or unknown response rate, unclear or unsystematic methods of eliciting preferences or other sample or measurement bias. However, sensitivity analysis of only the more robust and larger studies did not alter the finding of a preference for home care at the end of life in over 50% of patients. CONCLUSIONS Home care is the most common preference, with inpatient hospice care as second preference in advanced illness. Meeting these preferences could be important outcomes for services. Study designs in this area need to be improved.

Noninvasive ventilation for treatment of acute respiratory failure in patients undergoing solid organ transplantation: a randomized trial.

CONTEXT Noninvasive ventilation (NIV) has been associated with lower rates of endotracheal intubation in populations of patients with acute respiratory failure. OBJECTIVE To compare NIV with standard treatment using supplemental oxygen administration to avoid endotracheal intubation in recipients of solid organ transplantation with acute hypoxemic respiratory failure. DESIGN AND SETTING Prospective randomized study conducted at a 14-bed, general intensive care unit of a university hospital. PATIENTS Of 238 patients who underwent solid organ transplantation from December 1995 to October 1997, 51 were treated for acute respiratory failure. Of these, 40 were eligible and 20 were randomized to each group. INTERVENTION Noninvasive ventilation vs standard treatment with supplemental oxygen administration. MAIN OUTCOME MEASURES The need for endotracheal intubation and mechanical ventilation at any time during the study, complications not present on admission, duration of ventilatory assistance, length of hospital stay, and intensive care unit mortality. RESULTS The 2 groups were similar at study entry. Within the first hour of treatment, 14 patients (70%) in the NIV group, and 5 patients (25%) in the standard treatment group improved their ratio of the PaO2 to the fraction of inspired oxygen (FIO2). Over time, a sustained improvement in PaO2 to FIO2 was noted in 12 patients (60%) in the NIV group, and in 5 patients (25%) randomized to standard treatment (P = .03). The use of NIV was associated with a significant reduction in the rate of endotracheal intubation (20% vs 70%; P = .002), rate of fatal complications (20% vs 50%; P = .05), length of stay in the intensive care unit by survivors (mean [SD] days, 5.5 [3] vs 9 [4]; P = .03), and intensive care unit mortality (20% vs 50%; P = .05). Hospital mortality did not differ. CONCLUSIONS These results indicate that transplantation programs should consider NIV in the treatment of selected recipients of transplantation with acute respiratory failure.

Patient preferences and expectations for care: determinants in patients with lumbar intervertebral disc herniation.

STUDY DESIGN Prospective observational cohort. OBJECTIVE To describe the baseline characteristics of patients with a diagnosis of intervertebral disc herniation who had different treatment preferences and the relationship of specific expectations with those preferences. SUMMARY OF BACKGROUND DATA Data were gathered from the observational cohort of the Spine Patient Outcomes Research Trial (SPORT). Patients in the observational cohort met eligibility requirements identical to those of the randomized cohort, but declined randomization, receiving instead the treatment of their choice. METHODS Baseline preference and expectation data were acquired at the time of enrollment of the patient, before exposure to the informed consent process. Univariate analyses were performed using a t test for continuous variables and chi for categorical variables. Multivariate analyses were also performed with ANCOVA for continuous variables and logistic regression for categorical variables. Multiple logistic regression models were developed in a forward stepwise fashion using blocks of variables. RESULTS More patients preferred operative care: 67% preferred surgery, 28% preferred nonoperative treatment, and 6% were unsure; 53% of those preferring surgery stated a definite preference, whereas only 18% of those preferring nonoperative care had a definite preference. Patients preferring surgery were younger, had lower levels of education, and higher levels of unemployment/disability. This group also reported higher pain, worse physical and mental functioning, more back pain related disability, a longer duration of symptoms, and more opiate use. Gender, race, comorbidities, and use of other therapies did not differ significantly across preference groups. Patients' expectations regarding improvement with nonoperative care was the strongest predictor of preference. CONCLUSION Patient expectations, particularly regarding the benefit of nonoperative treatment, are the primary determinant of surgery preference among patients with lumbar intervertebral disc herniation. Demographic, functional status, and prior treatment experience had significant associations with patients' expectations and preferences.

Best--worst scaling: What it can do for health care research and how to do it.

Statements like "quality of care is more highly valued than waiting time" can neither be supported nor refuted by comparisons of utility parameters from a traditional discrete choice experiment (DCE). Best--worst scaling can overcome this problem because it asks respondents to perform a different choice task. However, whilst the nature of the best--worst task is generally understood, there are a number of issues relating to the design and analysis of a best--worst choice experiment that require further exposition. This paper illustrates how to aggregate and analyse such data and using a quality of life pilot study demonstrates how richer insights can be drawn by the use of best--worst tasks.

Assessment for selection for the health care professions and specialty training: consensus statement and recommendations from the Ottawa 2010 Conference.

Assessment for selection in medicine and the health professions should follow the same quality assurance processes as in-course assessment. The literature on selection is limited and is not strongly theoretical or conceptual. For written testing, there is evidence of the predictive validity of Medical College Admission Test (MCAT) for medical school and licensing examination performance. There is also evidence for the predictive validity of grade point average, particularly in combination with MCAT for graduate entry but little evidence about the predictive validity of school leaver scores. Interviews have not been shown to be robust selection measures. Studies of multiple mini-interviews have indicated good predictive validity and reliability. Of other measures used in selection, only the growing interest in personality testing appears to warrant future work. Widening access to medical and health professional programmes is an increasing priority and relates to the social accountability mandate of medical and health professional schools. While traditional selection measures do discriminate against various population groups, there is little evidence on the effect of non-traditional measures in widening access. Preparation and outreach programmes show most promise. In summary, the areas of consensus for assessment for selection are small in number. Recommendations for future action focus on the adoption of principles of good assessment and curriculum alignment, use of multi-method programmatic approaches, development of interdisciplinary frameworks and utilisation of sophisticated measurement models. The social accountability mandate of medical and health professional schools demands that social inclusion, workforce issues and widening of access are embedded in the principles of good assessment for selection.

[Palliative care in Germany].

The delivery of palliative care in Germany is still characterized by a wide-spread undersupply both for inpatients and outpatients. Nevertheless over the last 15 years progress has also been made in Germany, which is pleasing and which has directed professional and public attention increasingly to the situation of the incurably ill and dying. In the course of this development the first structures for specialized palliative care have been established. In particular the situation for inpatients in hospitals and hospices is pleasing, even if a satisfaction for total coverage is not yet reached. More seriously however is the demand for the outpatients. Financial means, which are steered so far only rudimentarily for palliative care, must be made sufficiently available, in order to be able to meet the demand with the help of appropriate structural offers. It is important to realize the needs of the incurably ill and dying and of their relatives and friends. Our society has to call attention to this subject and it should be placed on the healthpolitical agenda as a topic of the highest priority level. The current developments in the federation and in the federal states are encouraging and allowing hope that the delivery of palliative care for all who need it (and not only the ill) will improve further in the coming years.

What do medical schools teach about women's health and gender differences?

PURPOSE To examine the curricula of U.S. medical schools to assess the inclusion of women's health and gender-specific information and identify institutional characteristics associated with this content. METHOD Using data from the Association of American Medical Colleges' Curriculum Management and Information Tool (CurrMIT), in November 2003 to February 2004 the authors performed a curriculum search of schools that entered course/clerkships in CurrMIT to identify interdisciplinary women's health or gender-specific courses/clerkships. A subset of schools that entered comprehensive information in CurrMIT was searched for a specified list of women's health topics and or gender-specific content on any topic. Statistical analyses were performed to assess the relationship between frequency of topics and school characteristics. RESULTS The authors identified 95 schools that entered related courses/clerkships. Ten courses/clerkships at nine schools met criteria for an interdisciplinary women's health course/clerkship. In the subset of 60 schools with comprehensive CurrMIT information, 18 specified women's health topics were identified, as well as 24 topics on gender-specific content, for a total of 42 topics. The number of topics taught ranged from zero to 26 (mean = 11). More than 50% of these schools taught 11 of the 18 specified topics, while fewer than 30% included gender-specific topics. There was no association in bivariate analysis between the mean number of topics taught and schools' characteristics; however, a women's health program (p= .01) and female dean (p= .06) were positively associated in a regression model. CONCLUSIONS Few schools offer interdisciplinary women's health courses/clerkships or include gender-specific information in their curricula. A designated women's health program may increase this content in schools' curricula.

Economic implications of nighttime attending intensivist coverage in a medical intensive care unit.

OBJECTIVE Our objective was to assess the cost implications of changing the intensive care unit staffing model from on-demand presence to mandatory 24-hr in-house critical care specialist presence. DESIGN A pre-post comparison was undertaken among the prospectively assessed cohorts of patients admitted to our medical intensive care unit 1 yr before and 1 yr after the change. Our data were stratified by Acute Physiology and Chronic Health Evaluation III quartile and whether a patient was admitted during the day or at night. Costs were modeled using a generalized linear model with log-link and γ-distributed errors. SETTING A large academic center in the Midwest. PATIENTS All patients admitted to the adult medical intensive care unit on or after January 1, 2005 and discharged on or before December 31, 2006. Patients receiving care under both staffing models were excluded. INTERVENTION Changing the intensive care unit staffing model from on-demand presence to mandatory 24-hr in-house critical care specialist presence. MEASUREMENTS AND MAIN RESULTS Total cost estimates of hospitalization were calculated for each patient starting from the day of intensive care unit admission to the day of hospital discharge. Adjusted mean total cost estimates were 61% lower in the post period relative to the pre period for patients admitted during night hours (7 pm to 7 am) who were in the highest Acute Physiology and Chronic Health Evaluation III quartile. No significant differences were seen at other severity levels. The unadjusted intensive care unit length of stay fell in the post period relative to the pre period (3.5 vs. 4.8) with no change in non-intensive care unit length of stay. CONCLUSIONS We find that 24-hr intensive care unit intensivist staffing reduces lengths of stay and cost estimates for the sickest patients admitted at night. The costs of introducing such a staffing model need to be weighed against the potential total savings generated for such patients in smaller intensive care units, especially ones that predominantly care for lower-acuity patients.

Reforming the health sector in developing countries: the central role of policy analysis.

Policy analysis is an established discipline in the industrialized world, yet its application to developing countries has been limited. The health sector in particular appears to have been neglected. This is surprising because there is a well recognized crisis in health systems, and prescriptions abound of what health policy reforms countries should introduce. However, little attention has been paid to how countries should carry out reforms, much less who is likely to favour or resist such policies. This paper argues that much health policy wrongly focuses attention on the content of reform, and neglects the actors involved in policy reform (at the international, national sub-national levels), the processes contingent on developing and implementing change and the context within which policy is developed. Focus on policy content diverts attention from understanding the processes which explain why desired policy outcomes fail to emerge. The paper is organized in 4 sections. The first sets the scene, demonstrating how the shift from consensus to conflict in health policy established the need for a greater emphasis on policy analysis. The second section explores what is meant by policy analysis. The third investigates what other disciplines have written that help to develop a framework of analysis. And the final section suggests how policy analysis can be used not only to analyze the policy process, but also to plan.

Short-term medical service trips: a systematic review of the evidence.

Short-term medical service trips (MSTs) aim to address unmet health care needs of low- and middle-income countries. The lack of critically reviewed empirical evidence of activities and outcomes is a concern. Developing evidence-based recommendations for health care delivery requires systematic research review. I focused on MST publications with empirical results. Searches in May 2013 identified 67 studies published since 1993, only 6% of the published articles on the topic in the past 20 years. Nearly 80% reported on surgical trips. Although the MST field is growing, its medical literature lags behind, with nearly all of the scholarly publications lacking significant data collection. By incorporating data collection into service trips, groups can validate practices and provide information about areas needing improvement.

Barriers and facilitators to implement shared decision making in multidisciplinary sciatica care: a qualitative study

BACKGROUND The Dutch multidisciplinary sciatica guideline recommends that the team of professionals involved in sciatica care and the patient together decide on surgical or prolonged conservative treatment (shared decision making [SDM]). Despite this recommendation, SDM is not yet integrated in sciatica care. Existing literature concerning barriers and facilitators to SDM implementation mainly focuses on one discipline only, whereas multidisciplinary care may involve other barriers and facilitators, or make these more complex for both professionals and patients. Therefore, this qualitative study aims to identify barriers and facilitators perceived by patients and professionals for SDM implementation in multidisciplinary sciatica care. METHODS We conducted 40 semi-structured interviews with professionals involved in sciatica care (general practitioners, physical therapists, neurologists, neurosurgeons, and orthopedic surgeons) and three focus groups among patients (six to eight per group). The interviews and focus groups were audiotaped and transcribed in full. Reported barriers and facilitators were classified according to the framework of Grol and Wensing. The software package Atlas.ti 7.0 was used for analysis. RESULTS Professionals reported 53 barriers and 5 facilitators, and patients 35 barriers and 18 facilitators for SDM in sciatica care. Professionals perceived most barriers at the level of the organizational context, and facilitators at the level of the individual professional. Patients reported most barriers and facilitators at the level of the individual professional. Several barriers and facilitators correspond with barriers and facilitators found in the literature (e.g., lack of time, motivation) but also new barriers and facilitators were identified. Many of these new barriers mentioned by both professionals and patients were related to the multidisciplinary setting, such as lack of visibility, lack of trust in expertise of other disciplines, and lack of communication between disciplines. CONCLUSIONS This study identified barriers and facilitators for SDM in the multidisciplinary sciatica setting, by both professionals and patients. It is clear that more barriers than facilitators are perceived for implementation of SDM in sciatica care. Newly identified barriers and facilitators are related to the multidisciplinary care setting. Therefore, an effective implementation strategy of SDM in a multidisciplinary setting such as in sciatica care should focus on these barriers and facilitators.

Care Seeking for Neonatal Illness in Low- and Middle-Income Countries: A Systematic Review

BACKGROUND Despite recent achievements to reduce child mortality, neonatal deaths continue to remain high, accounting for 41% of all deaths in children under five years of age worldwide, of which over 90% occur in low- and middle-income countries (LMICs). Infections are a leading cause of death and limitations in care seeking for ill neonates contribute to high mortality rates. As estimates for care-seeking behaviors in LMICs have not been studied, this review describes care seeking for neonatal illnesses in LMICs, with particular attention to type of care sought. METHODS AND FINDINGS We conducted a systematic literature review of studies that reported the proportion of caregivers that sought care for ill or suspected ill neonates in LMICs. The initial search yielded 784 studies, of which 22 studies described relevant data from community household surveys, facility-based surveys, and intervention trials. The majority of studies were from South Asia (n = 17/22), set in rural areas (n = 17/22), and published within the last 4 years (n = 18/22). Of the 9,098 neonates who were ill or suspected to be ill, 4,320 caregivers sought some type of care, including care from a health facility (n = 370) or provider (n = 1,813). Care seeking ranged between 10% and 100% among caregivers with a median of 59%. Care seeking from a health care provider yielded a similar range and median, while care seeking at a health care facility ranged between 1% and 100%, with a median of 20%. Care-seeking estimates were limited by the few studies conducted in urban settings and regions other than South Asia. There was a lack of consistency regarding illness, care-seeking, and care provider definitions. CONCLUSIONS There is a paucity of data regarding newborn care-seeking behaviors; in South Asia, care seeking is low for newborn illness, especially in terms of care sought from health care facilities and medically trained providers. There is a need for representative data to describe care-seeking patterns in different geographic regions and better understand mechanisms to enhance care seeking during this vulnerable time period.

Association of Intracerebral Hemorrhage Among Patients Taking Non–Vitamin K Antagonist vs Vitamin K Antagonist Oral Anticoagulants With In-Hospital Mortality

Importance Although non–vitamin K antagonist oral anticoagulants (NOACs) are increasingly used to prevent thromboembolic disease, there are limited data on NOAC-related intracerebral hemorrhage (ICH). Objective To assess the association between preceding oral anticoagulant use (warfarin, NOACs, and no oral anticoagulants [OACs]) and in-hospital mortality among patients with ICH. Design, Setting, and Participants Retrospective cohort study of 141 311 patients with ICH admitted from October 2013 to December 2016 to 1662 Get With The Guidelines–Stroke hospitals. Exposures Anticoagulation therapy before ICH, defined as any use of OACs within 7 days prior to hospital arrival. Main Outcomes and Measures In-hospital mortality. Results Among 141 311 patients with ICH (mean [SD] age, 68.3 [15.3] years; 48.1% women), 15 036 (10.6%) were taking warfarin and 4918 (3.5%) were taking NOACs preceding ICH, and 39 585 (28.0%) and 5783 (4.1%) were taking concomitant single and dual antiplatelet agents, respectively. Patients with prior use of warfarin or NOACs were older and had higher prevalence of atrial fibrillation and prior stroke. Acute ICH stroke severity (measured by the National Institutes of Health Stroke Scale) was not significantly different across the 3 groups (median, 9 [interquartile range, 2-21] for warfarin, 8 [2-20] for NOACs, and 8 [2-19] for no OACs). The unadjusted in-hospital mortality rates were 32.6% for warfarin, 26.5% for NOACs, and 22.5% for no OACs. Compared with patients without prior use of OACs, the risk of in-hospital mortality was higher among patients with prior use of warfarin (adjusted risk difference [ARD], 9.0% [97.5% CI, 7.9% to 10.1%]; adjusted odds ratio [AOR], 1.62 [97.5% CI, 1.53 to 1.71]) and higher among patients with prior use of NOACs (ARD, 3.3% [97.5% CI, 1.7% to 4.8%]; AOR, 1.21 [97.5% CI, 1.11-1.32]). Compared with patients with prior use of warfarin, patients with prior use of NOACs had a lower risk of in-hospital mortality (ARD, −5.7% [97.5% CI, −7.3% to −4.2%]; AOR, 0.75 [97.5% CI, 0.69 to 0.81]). The difference in mortality between NOAC-treated patients and warfarin-treated patients was numerically greater among patients with prior use of dual antiplatelet agents (32.7% vs 47.1%; ARD, −15.0% [95.5% CI, −26.3% to −3.8%]; AOR, 0.50 [97.5% CI, 0.29 to 0.86]) than among those taking these agents without prior antiplatelet therapy (26.4% vs 31.7%; ARD, −5.0% [97.5% CI, −6.8% to −3.2%]; AOR, 0.77 [97.5% CI, 0.70 to 0.85]), although the interaction P value (.07) was not statistically significant. Conclusions and Relevance Among patients with ICH, prior use of NOACs or warfarin was associated with higher in-hospital mortality compared with no OACs. Prior use of NOACs, compared with prior use of warfarin, was associated with lower risk of in-hospital mortality.

What is the best way to help caregivers in cancer and palliative care? A systematic literature review of interventions and their effectiveness.

Informal carers in cancer and palliative care are known to have high needs and psychological morbidity, yet a literature review identified few targeted interventions. This systematic review of interventions for carers of patients using home cancer and palliative care services searched Medline, CancerLit, Psycinfo and Cinahl databases. The terms used were carer(s), caregiver(s), palliative and cancer. Papers that reported interventions for adults actively providing informal care for noninstitutionalized cancer and palliative care patients were reviewed. Twenty-two interventions were identified, comprising home nursing care (four), respite services (three), social networks and activity enhancement (two), problem solving and education (three) and group work (10). Of these, nine were delivered solely to carers (i.e., were targeted services). Only six of the carers' interventions had been evaluated, two of these had used a randomized control trial (RCT; grades IB), three employed a single group methodology (two prospective grades IIIC and one retrospective grade IIIC) and one was evaluated using facilitator feedback. There was a lack of outcome evaluation designs, small sample sizes and a reliance on intervention descriptions and formative evaluations. Methodological challenges may mean alternatives to 'pure' RCTs should be considered. The current evidence contributes more to understanding feasibility and acceptability than to effectiveness. Practitioners and evaluators must prioritize the further development of intervention studies.

National study of physician awareness and adherence to cardiovascular disease prevention guidelines.

BACKGROUND Few data have evaluated physician adherence to cardiovascular disease (CVD) prevention guidelines according to physician specialty or patient characteristics, particularly gender. METHODS AND RESULTS An online study of 500 randomly selected physicians (300 primary care physicians, 100 obstetricians/gynecologists, and 100 cardiologists) used a standardized questionnaire to assess awareness of, adoption of, and barriers to national CVD prevention guidelines by specialty. An experimental case study design tested physician accuracy and determinants of CVD risk level assignment and application of guidelines among high-, intermediate-, or low-risk patients. Intermediate-risk women, as assessed by the Framingham risk score, were significantly more likely to be assigned to a lower-risk category by primary care physicians than men with identical risk profiles (P<0.0001), and trends were similar for obstetricians/gynecologists and cardiologists. Assignment of risk level significantly predicted recommendations for lifestyle and preventive pharmacotherapy. After adjustment for risk assignment, the impact of patient gender on preventive care was not significant except for less aspirin (P<0.01) and more weight management recommended (P<0.04) for intermediate-risk women. Physicians did not rate themselves as very effective in their ability to help patients prevent CVD. Fewer than 1 in 5 physicians knew that more women than men die each year from CVD. CONCLUSIONS Perception of risk was the primary factor associated with CVD preventive recommendations. Gender disparities in recommendations for preventive therapy were explained largely by the lower perceived risk despite similar calculated risk for women versus men. Educational interventions for physicians are needed to improve the quality of CVD preventive care and lower morbidity and mortality from CVD for men and women.

Management of patients with sore throats in relation to guidelines: An interview study in Sweden

OBJECTIVE To explore how a group of Swedish general practitioners (GPs) manage patients with a sore throat in relation to current guidelines as expressed in interviews. DESIGN Qualitative content analysis was used to analyse semi-structured interviews. SETTING Swedish primary care. SUBJECTS A strategic sample of 25 GPs. MAIN OUTCOME MEASURES Perceived management of sore throat patients. RESULTS It was found that nine of the interviewed GPs were adherent to current guidelines for sore throat and 16 were non-adherent. The two groups differed in terms of guideline knowledge, which was shared within the team for adherent GPs while idiosyncratic knowledge dominated for the non-adherent GPs. Adherent GPs had no or low concerns for bacterial infections and differential diagnosis whilst non-adherent GPs believed that in patients with a sore throat any bacterial infection should be identified and treated with antibiotics. Patient history and examination was mainly targeted by adherent GPs whilst for non-adherent GPs it was often redundant. Non-adherent GPs reported problems getting patients to abstain from antibiotics, whilst no such problems were reported in adherent GPs. CONCLUSION This interview study of sore throat management in a strategically sampled group of Swedish GPs showed that while two-thirds were non-adherent and had a liberal attitude to antibiotics one-third were guideline adherent with a restricted view on antibiotics. Non-adherent GPs revealed significant knowledge gaps. Adherent GPs had discussed guidelines within the primary care team while non-adherent GPs had not. Guideline implementation thus seemed to be promoted by knowledge shared in team discussions.

Mental Health Support Provided Throughout the Bariatric Surgery Clinical Pathway in French Specialized Care Centers for Obesity

Pre-operative psychological assessment is recommended by international guidelines for bariatric surgery candidates. Thereby, service teams caring for bariatric patients should include at least one mental health provider (e.g., a psychologist or psychiatrist). The objective of this study was to evaluate the psychology and psychiatry resources and practices in the 37 specialized obesity centers (CSOs) created by the French Ministry of Health. CSO coordinators were contacted by e-mail to collect general information on the centers (e.g., number of bariatric operations). Secondly, psychologists and psychiatrists of each center completed an anonymous questionnaire assessing their professional practices and their organization of care pathways. The vast majority of CSO coordinators (81%, n = 26/32) answered our survey. These results show significant differences and shortages in terms of the psychology/psychiatry resources available. Most of the psychologists (n = 26/31) and psychiatrists (n = 10/10) stated that they systematically meet new patients only before surgery (56%) or both before and after the operation (30%); however, some psychologists and psychiatrists (14%) do not systematically meet all the patients (before and/or after surgery). Nevertheless, all the professionals provide psychology assessments, and about 75% of them offer a psychological follow-up, indicating a similarity regarding the practices of psychologists and psychiatrists. Our results highlight the place of psychological/psychiatric evaluations in French CSOs and emphasize the absence of mental health providers in several of these services. Post-operative psychological follow-up is not usually provided. It would be appropriate to create clear recommendations for post-operative psychological or psychiatric long-term follow-up.

Are dual eligibles admitted to poorer quality skilled nursing facilities?

BACKGROUND Dual eligibles, persons who qualify for both Medicare and Medicaid coverage, often receive poorer quality care relative to other Medicare beneficiaries. OBJECTIVES To determine whether dual eligibles are discharged to lower quality post-acute skilled nursing facilities (SNFs) compared with Medicare-only beneficiaries. RESEARCH DESIGN Following the random utility maximization model, we specified a discharge function using a conditional logit model and tested how this discharge rule varied by dual-eligibility status. SUBJECTS A total of 692,875 Medicare fee-for-service patients (22% duals) who were discharged for Medicare paid SNF care between July 2004 and June 2005. MEASURES Medicare enrollment and the Medicaid Analytic Extract files were used to determine dual eligibility. The proportion of Medicaid patients and nursing staff characteristics provided measures of SNF quality. RESULTS Duals are more likely to be discharged to SNFs with a higher share of Medicaid patients and fewer nurses. These results are robust to estimation with an alternative subsample of patients based on primary diagnoses, propensity of being dual eligible, and likelihood of remaining in the nursing home. CONCLUSIONS Disparities exist in access to quality SNF care for duals. Strategies to improve discharge planning processes are required to redirect patients to higher quality providers, regardless of Medicaid eligibility.

Gender-dependent differences in outcome after the treatment of infection in hospitalized patients.

CONTEXT While it is established that management strategies and outcomes differ by gender for many diseases, its effect on infection has not been adequately studied. OBJECTIVE To investigate the role of gender among hospitalized patients treated for infection. DESIGN Observational cohort study conducted during a 26-month period from December 1996 through January 1999. SETTING University-affiliated hospital. PARTICIPANTS A total of 892 patients in the surgical units of the hospital with 1470 consecutive infectious episodes (782 in men and 688 in women). MAIN OUTCOME MEASURES Mortality during hospitalization by gender for infection episodes overall and for specific infectious sites, including lung, peritoneum, bloodstream, catheter, urine, surgical site, and skin/soft tissue. RESULTS Among all infections, there was no significant difference in mortality based on gender (men, 11.1% vs women, 14.2%; P = .07). After logistic regression analysis, factors independently associated with mortality included higher APACHE (Acute Physiology and Chronic Health Evaluation) II score, older age, malignancy, blood transfusion, and diagnosis of infection more than 7 days after admission, but not gender (female odds ratio [OR] for death, 1.32; 95% confidence interval [CI], 0.90-1.94; P = .16). Mortality was higher in women for lung (men, 18% vs women, 34%; P = .002) and soft tissue (men, 2% vs women, 10%; P < or = .05) infection; for other infectious sites, mortality did not differ by gender. Factors associated with mortality due to pneumonia by logistic regression included higher APACHE II score, malignancy, diabetes mellitus, diagnosis of infection more than 7 days after admission, older age, transplantation, and female gender (OR for death, 2.25; 95% CI, 1.17-4.32; P = .02). CONCLUSIONS Although gender may not be predictive of mortality among all infections, women appear to be at increased risk for death from hospital-acquired pneumonia, even after controlling for other comorbidities.

How can health care organizations be reliably compared?: Lessons from a national survey of patient experience.

BACKGROUND Patient experience is increasingly used to assess organizational performance, for example in public reporting or pay-for-performance schemes. Conventional approaches using 95% confidence intervals are commonly used to determine required survey samples or to report performance but these may result in unreliable organizational comparisons. METHODS We analyzed data from 2.2 million patients who responded to the English 2009 General Practice Patient Survey, which included 45 patient experience questions nested within 6 different care domains (access, continuity of care, communication, anticipatory care planning, out-of-hours care, and overall care satisfaction). For each question, unadjusted and case-mix adjusted (for age, sex, and ethnicity) organization-level reliability, and intraclass correlation coefficients were calculated. RESULTS Mean responses per organization ranged from 23 to 256 for questions evaluating primary care practices, and from 1454 to 2758 for questions evaluating out-of-hours care organizations. Adjusted and unadjusted reliability values were similar. Twenty-six questions had excellent reliability (≥0.90). Seven nurse communication questions had very good reliability (≥0.85), but 3 anticipatory care planning questions had lower reliability (<0.70). Reliability was typically <0.70 for questions with <100 mean responses per practice, usually indicating questions which only a subset of patients were eligible to answer. Nine questions had both excellent reliability and high intraclass correlation coefficients (≥0.10) indicating both reliable measurement and substantial performance variability. CONCLUSIONS High reliability is a necessary property of indicators used to compare health care organizations. Using the English General Practice Patient Survey as a case study, we show how reliability and intraclass correlation coefficients can be used to select measures to support robust organizational comparisons, and to design surveys that will both provide high-quality measurement and optimize survey costs.

Ansichten von Hausärzten zur Versorgung von unheilbar kranken Patienten am Lebensende - Ergebnisse einer Befragung in Niedersachsen

Background: Family doctors play an important role in the health care for terminal ill and patients. The current level of palliative care in Germany is strongly criticised, however, empirical data is scare, particularly with respect to family doctors. Methods: Therefore, the attitudes of family doctors (sample: n= 257) in four representative regions in Lower Saxony were studied by using semi-structured telephone interviews. This was part of a health system researchers’ expert report. Results: 71doctors could be interviewed (28%). On the average, they cared for four palliative patients with cancer diseases and eight palliative patients with other diseases than cancer at that time. Many of the doctors were available for their patients around the clock, particularly in the final phase. The main area for improvement was considered to be the psychosocial support – rather than pain therapy, which is usually focussed. Furthermore, a considerable openness for the establishment of new palliative care structures was shown. Conclusion: Family doctors are highly motivated for palliative care and open for improvements. In the process, the diversity of opinion among professions and disciplines about the current situation and the further development of palliative care should be respected and considered.

Gender differences in the utilization of health care services.

BACKGROUND Studies have shown that women use more health care services than men. We used important independent variables, such as patient sociodemographics and health status, to investigate gender differences in the use and costs of these services. METHODS New adult patients (N = 509) were randomly assigned to primary care physicians at a university medical center. Their use of health care services and associated charges were monitored for 1 year of care. Self-reported health status was measured using the Medical Outcomes Study Short Form-36 (SF-36). We controlled for health status, sociodemographic information, and primary care physician specialty in the statistical analyses. RESULTS Women had significantly lower self-reported health status and lower mean education and income than men. Women had a significantly higher mean number of visits to their primary care clinic and diagnostic services than men. Mean charges for primary care, specialty care, emergency treatment, diagnostic services, and annual total charges were all significantly higher for women than men; however, there were no differences for mean hospitalizations or hospital charges. After controlling for health status, sociodemographics, and clinic assignment, women still had higher medical charges for all categories of charges except hospitalizations. CONCLUSIONS Women have higher medical care service utilization and higher associated charges than men. Although the appropriateness of these differences was not determined, these findings have implications for health care.

Hospital volume and the outcomes of mechanical ventilation.

BACKGROUND An increased volume of patients is associated with improved survival in numerous high-risk medical and surgical conditions. The relationship between the number of patients admitted (hospital volume) and outcome among patients with critical illnesses is unknown. METHODS We analyzed data from 20,241 nonsurgical patients receiving mechanical ventilation at 37 acute care hospitals in the Acute Physiology and Chronic Health Evaluation clinical information system from 2002 through 2003. Multivariate analyses were performed to adjust for the severity of illness and other differences in the case mix. RESULTS An increase in hospital volume was associated with improved survival among patients receiving mechanical ventilation in the intensive care unit (ICU) and in the hospital. Admission to a hospital in the highest quartile according to volume (i.e., >400 patients receiving mechanical ventilation per year) was associated with a 37 percent reduction in the adjusted odds of death in the ICU as compared with admission to hospitals in the lowest quartile (< or =150 patients receiving mechanical ventilation per year, P<0.001). In-hospital mortality was similarly reduced (adjusted odds ratio, 0.66; 95 percent confidence interval, 0.52 to 0.83; P<0.001). A typical patient in a hospital in a low-volume quartile would have an adjusted in-hospital mortality of 34.2 percent as compared with 25.5 percent in a hospital in a high-volume quartile. Among survivors, there were no significant trends in the length of stay in the ICU or the hospital. CONCLUSIONS Mechanical ventilation of patients in a hospital with a high case volume is associated with reduced mortality. Further research is needed to determine the mechanism of the relationship between volume and outcome among patients with a critical illness.

Interactions between Non-Physician Clinicians and Industry: A Systematic Review

BACKGROUND With increasing restrictions placed on physician-industry interactions, industry marketing may target other health professionals. Recent health policy developments confer even greater importance on the decision making of non-physician clinicians. The purpose of this systematic review is to examine the types and implications of non-physician clinician-industry interactions in clinical practice. METHODS AND FINDINGS We searched MEDLINE and Web of Science from January 1, 1946, through June 24, 2013, according to PRISMA guidelines. Non-physician clinicians eligible for inclusion were: Registered Nurses, nurse prescribers, Physician Assistants, pharmacists, dieticians, and physical or occupational therapists; trainee samples were excluded. Fifteen studies met inclusion criteria. Data were synthesized qualitatively into eight outcome domains: nature and frequency of industry interactions; attitudes toward industry; perceived ethical acceptability of interactions; perceived marketing influence; perceived reliability of industry information; preparation for industry interactions; reactions to industry relations policy; and management of industry interactions. Non-physician clinicians reported interacting with the pharmaceutical and infant formula industries. Clinicians across disciplines met with pharmaceutical representatives regularly and relied on them for practice information. Clinicians frequently received industry "information," attended sponsored "education," and acted as distributors for similar materials targeted at patients. Clinicians generally regarded this as an ethical use of industry resources, and felt they could detect "promotion" while benefiting from industry "information. " Free samples were among the most approved and common ways that clinicians interacted with industry. Included studies were observational and of varying methodological rigor; thus, these findings may not be generalizable. This review is, however, the first to our knowledge to provide a descriptive analysis of this literature. CONCLUSIONS Non-physician clinicians' generally positive attitudes toward industry interactions, despite their recognition of issues related to bias, suggest that industry interactions are normalized in clinical practice across non-physician disciplines. Industry relations policy should address all disciplines and be implemented consistently in order to mitigate conflicts of interest and address such interactions' potential to affect patient care.

Hospital and 1-year survival of patients admitted to intensive care units with acute exacerbation of chronic obstructive pulmonary disease.

OBJECTIVE To describe outcomes and identify variables associated with hospital and 1-year survival for patients admitted to an intensive care unit (ICU) with an acute exacerbation of chronic obstructive pulmonary disease (COPD). DESIGN Prospective, multicenter, inception cohort study. SETTING Forty-two ICUs at 40 US hospitals. PATIENTS A total of 362 admissions for COPD exacerbation selected from the Acute Physiology and Chronic Health Evaluation (APACHE) III database of 17,440 ICU admissions. MEASUREMENTS AND RESULTS Hospital mortality for the 362 admissions was 24%. For the 167 patients aged 65 years or older, mortality was 30% at hospital discharge, 41% at 90 days, 47% at 180 days, and 59% at 1 year. Median survival for all patients was 224 days, and median survival for the patients who died within 1 year was 30.5 days. On multiple regression analysis, variables associated with hospital mortality included age, severity of respiratory and nonrespiratory organ system dysfunction, and hospital length of stay before ICU admission. Development of nonrespiratory organ system dysfunction was the major predictor of hospital mortality (60% of total explanatory power) and 180-day outcomes (54% of explanatory power). Respiratory physiological variables (respiratory rate, serum pH, PaCO2, PaO2, and alveolar-arterial difference in partial pressure of oxygen [PAO2-PaO2]) indicative of advanced dysfunction were more strongly associated with 180-day mortality rates (22% of explanatory power) than hospital death rates (4% of explanatory power). After controlling for severity of illness, mechanical ventilation at ICU admission was not associated with either hospital mortality or subsequent survival. CONCLUSIONS Patients with COPD admitted to an ICU for an acute exacerbation have a substantial hospital mortality (24%). For patients aged 65 years or older, mortality doubles in 1 year from 30% to 59%. Hospital and longer-term mortality is closely associated with development of nonrespiratory organ system dysfunction; severity of the underlying respiratory function substantially influences mortality following hospital discharge. The need for mechanical ventilation at ICU admission did not influence either short- or long-term outcomes. Physicians should be aware of these relationships when making treatment decisions or evaluating new therapies.

Thresholds for the cost–effectiveness of interventions: alternative approaches

Many countries use the cost-effectiveness thresholds recommended by the World Health Organization's Choosing Interventions that are Cost-Effective project (WHO-CHOICE) when evaluating health interventions. This project sets the threshold for cost-effectiveness as the cost of the intervention per disability-adjusted life-year (DALY) averted less than three times the country's annual gross domestic product (GDP) per capita. Highly cost-effective interventions are defined as meeting a threshold per DALY averted of once the annual GDP per capita. We argue that reliance on these thresholds reduces the value of cost-effectiveness analyses and makes such analyses too blunt to be useful for most decision-making in the field of public health. Use of these thresholds has little theoretical justification, skirts the difficult but necessary ranking of the relative values of locally-applicable interventions and omits any consideration of what is truly affordable. The WHO-CHOICE thresholds set such a low bar for cost-effectiveness that very few interventions with evidence of efficacy can be ruled out. The thresholds have little value in assessing the trade-offs that decision-makers must confront. We present alternative approaches for applying cost-effectiveness criteria to choices in the allocation of health-care resources.

Homelessness and health.

Homelessness affects tens of thousands of canadians and has important health implications. Homeless people are at increased risk of dying prematurely and suffer from a wide range of health problems, including seizures, chronic obstructive pulmonary disease, musculoskeletal disorders, tuberculosis, and skin and foot problems. Homeless people also face significant barriers that impair their access to health care. More research is needed to identify better ways to deliver care to this population.

American Society of Clinical Oncology policy statement: the role of the oncologist in cancer prevention and risk assessment.

Oncologists have a critical opportunity to utilize risk assessment and cancer prevention strategies to interrupt the initiation or progression of cancer in cancer survivors and individuals at high risk of developing cancer. Expanding knowledge about the natural history and prognosis of cancers positions oncologists to advise patients regarding the risk of second malignancies and treatment-related cancers. In addition, as recognized experts in the full spectrum of cancer care, oncologists are afforded opportunities for involvement in community-based cancer prevention activities. Although oncologists are currently providing many cancer prevention and risk assessment services to their patients, economic barriers exist, including inadequate or lack of insurance, that may compromise uniform patient access to these services. Additionally, insufficient reimbursement for existing and developing interventions may discourage patient access to these services. The American Society of Clinical Oncology (ASCO), the medical society representing cancer specialists involved in patient care and clinical research, is committed to supporting oncologists in their wide-ranging involvement in cancer prevention. This statement on risk assessment and prevention counseling, although not intended to be a comprehensive overview of cancer prevention describes the current role of oncologists in risk assessment and prevention; provides examples of risk assessment and prevention activities that should be offered by oncologists; identifies potential opportunities for coordination between oncologists and primary care physicians in prevention education and coordination of care for cancer survivors; describes ASCO's involvement in education and training of oncologists regarding prevention; and proposes improvement in the payment environment to encourage patient access to these services.

Evaluating the impact of pharmacists in mental health: a systematic review.

Efforts to improve the outcomes of patients with mental illness often have involved incorporating the skills of a variety of health care professionals into collaborative care models. For over 30 years, clinical pharmacists have contributed to these care models in capacities ranging from educator to consultant to provider. This systematic review evaluates the quantity and quality of medical literature examining the impact of pharmacists in mental health from 1972-2003. Although we identified approximately 35 publications describing the roles of clinical pharmacists in this regard, only 16 were of sufficient scientific rigor to permit evaluation and comparison. The 16 studies were divided equally between inpatient and outpatient settings and were conducted in a variety of health care organizations (e.g., Veterans Administration, health maintenance organizations, community mental health clinics, and nursing homes). Nine of the studies examined the role of pharmacists in providing treatment recommendations and patient education, five featured pharmacists as providers (with prescriptive authority), and the remaining two described the impact pharmacists have in delivering education to the psychiatric staff. Six of the 16 studies were prospective, but only three of these incorporated a randomization procedure for patients or facilities. Collectively, the results of the 16 studies were positive, demonstrating improvements in outcomes, prescribing practices, patient satisfaction, and resource use. Unfortunately, most of the investigations were small, and significant limitations in study design limited further comparison. Given the long history and anecdotal success of pharmacists in mental health care settings, additional multicenter cost-effectiveness trials are warranted to further support the role of the psychiatric pharmacist.

Prison health care: a review of the literature.

The prison population is increasing and the health problems of prisoners are considerable. Prison is designed with punishment, correction and rehabilitation to the community in mind and these goals may conflict with the aims of health care. A literature review showed that the main issues in prison health care are mental health, substance abuse and communicable diseases. Women prisoners and older prisoners have needs which are distinct from other prisoners. Health promotion and the health of the community outside prisons are desirable aims of prison health care. The delivery of effective health care to prisoners is dependent upon partnership between health and prison services and telemedicine is one possible mode of delivery.

Global and regional burden of hospital admissions for severe acute lower respiratory infections in young children in 2010: a systematic analysis

BACKGROUND The annual number of hospital admissions and in-hospital deaths due to severe acute lower respiratory infections (ALRI) in young children worldwide is unknown. We aimed to estimate the incidence of admissions and deaths for such infections in children younger than 5 years in 2010. METHODS We estimated the incidence of admissions for severe and very severe ALRI in children younger than 5 years, stratified by age and region, with data from a systematic review of studies published between Jan 1, 1990, and March 31, 2012, and from 28 unpublished population-based studies. We applied these incidence estimates to population estimates for 2010, to calculate the global and regional burden in children admitted with severe ALRI in that year. We estimated in-hospital mortality due to severe and very severe ALRI by combining incidence estimates with case fatality ratios from hospital-based studies. FINDINGS We identified 89 eligible studies and estimated that in 2010, 11·9 million (95% CI 10·3-13·9 million) episodes of severe and 3·0 million (2·1-4·2 million) episodes of very severe ALRI resulted in hospital admissions in young children worldwide. Incidence was higher in boys than in girls, the sex disparity being greatest in South Asian studies. On the basis of data from 37 hospital studies reporting case fatality ratios for severe ALRI, we estimated that roughly 265,000 (95% CI 160,000-450,000) in-hospital deaths took place in young children, with 99% of these deaths in developing countries. Therefore, the data suggest that although 62% of children with severe ALRI are treated in hospitals, 81% of deaths happen outside hospitals. INTERPRETATION Severe ALRI is a substantial burden on health services worldwide and a major cause of hospital referral and admission in young children. Improved hospital access and reduced inequities, such as those related to sex and rural status, could substantially decrease mortality related to such infection. Community-based management of severe disease could be an important complementary strategy to reduce pneumonia mortality and health inequities. FUNDING WHO.

Misunderstandings in prescribing decisions in general practice: qualitative study.

OBJECTIVES To identify and describe misunderstandings between patients and doctors associated with prescribing decisions in general practice. DESIGN Qualitative study. SETTING 20 general practices in the West Midlands and south east England. PARTICIPANTS 20 general practitioners and 35 consulting patients. MAIN OUTCOME MEASURES Misunderstandings between patients and doctors that have potential or actual adverse consequences for taking medicine. RESULTS 14 categories of misunderstanding were identified relating to patient information unknown to the doctor, doctor information unknown to the patient, conflicting information, disagreement about attribution of side effects, failure of communication about doctor's decision, and relationship factors. All the misunderstandings were associated with lack of patients' participation in the consultation in terms of the voicing of expectations and preferences or the voicing of responses to doctors' decisions and actions. They were all associated with potential or actual adverse outcomes such as non-adherence to treatment. Many were based on inaccurate guesses and assumptions. In particular doctors seemed unaware of the relevance of patients' ideas about medicines for successful prescribing. CONCLUSIONS Patients' participation in the consultation and the adverse consequences of lack of participation are important. The authors are developing an educational intervention that builds on these findings.

Ethical dilemmas in a randomized trial of asthma treatment: can Bayesian statistical analysis explain the results?

OBJECTIVES The original objective was to determine whether the use of bilevel positive airway pressure (BiPAP) ventilation would reduce the need for endotracheal intubation, the length of hospital stay, and hospital charges in patients with status asthmaticus. The development of physician treatment bias made patient enrollment difficult. The article subsequently describes the use of Bayesian statistics to explain study results when this bias occurs. METHODS This study was a prospective, randomized controlled clinical trial conducted over a 34.5-month period at an urban university hospital with an emergency department census of 94,000 annual visits. Patients remaining in status asthmaticus after initial standard treatment with inhaled beta-agonists and steroids were randomized to receive BiPAP ventilation plus standard treatment versus standard treatment alone (non-BiPAP), with intubation for either group as needed. Patients with concurrent cardiac or other pulmonary diseases were excluded. The primary outcome measures were endotracheal intubation rate and length of hospital stay. Secondary outcome measures included vital signs (respiratory rate, pulse rate, blood pressure), changes in expiratory peak flow, changes in pulse oximetry values, and hospital charges. Data were analyzed using Fisher's exact test, Mann-Whitney tests, and Bayesian statistics. For patients enrolled in the study more than once, data analysis was performed on the first enrollment only. RESULTS Nineteen patients were enrolled in the BiPAP group and 16 patients in the non-BiPAP group. Patients were frequently enrolled more than once and the data from the subsequent enrollments were excluded from the analysis. A marked decrease in enrollment, due to physician treatment bias, led to a premature termination of the study. Demographics showed that the groups were similar in age, sex, initial peak flow rate, and arterial blood gas measurements. There was a 7.3% increase (95% CI = -22 to +45) in the intubation rate in the non-BiPAP group (n = 2) compared with that for the BiPAP group (n = 1). No significant difference was seen in length of hospital stay or hospital charges, although there was a favorable trend toward the BiPAP group. Complications encountered in the BiPAP group included one patient with discomfort associated with the nasal BiPAP mask. Bayesian analysis demonstrated that in order for the collected data to be convincing at the 95% confidence level, the prior conviction among treating physicians that BiPAP was a successful treatment modality would have had to be 98.9%. CONCLUSIONS In this study, BiPAP appeared to have no deleterious effects in patients with status asthmaticus, with a trend toward decreased endotracheal intubation rate, decreased length of hospital stay, and decreased hospital charges. Although further study with more patients is needed to determine the clinical and statistical significance of this intervention, ethical concerns regarding withholding BiPAP treatment from the patients in the control group forced a premature termination of the study in the authors' institution.

Effect of clinical guidelines on medical practice: a systematic review of rigorous evaluations.

Although interest in clinical guidelines has never been greater, uncertainty persists about whether they are effective. The debate has been hampered by the lack of a rigorous overview. We have identified 59 published evaluations of clinical guidelines that met defined criteria for scientific rigour; 24 investigated guidelines for specific clinical conditions, 27 studied preventive care, and 8 looked at guidelines for prescribing or for support services. All but 4 of these studies detected significant improvements in the process of care after the introduction of guidelines and all but 2 of the 11 studies that assessed the outcome of care reported significant improvements. We conclude that explicit guidelines do improve clinical practice, when introduced in the context of rigorous evaluations. However, the size of the improvements in performance varied considerably.

This paper examines the potential impact of changes in medical care on changing population health in Lithuania, Hungary and Romania, with west Germany included for comparison. We used the concept of deaths from certain causes that should not occur in the presence of timely and effective health care (amenable mortality) and calculated the contribution of changes in mortality from these conditions to changes in life expectancy between birth and age 75 [e (0-75)] for the periods 1980/81 to 1988 and 1992 to 1997. Temporary life expectancy improved consistently in west Germany (men: 2.7 years, women: 1.6 years). In contrast, gains were relatively small in the other countries, except among Hungarian women, who gained 1.3 years. Romanian men lost 1.3 years. In the 1980s, falling infant mortality made a substantial contribution to improvements in temporary life expectancy in all countries, of about a quarter to half a year. Of this, more than half can be attributed to amenable conditions. At older ages, falling amenable mortality contributed about 40% among those aged over 40 in Germany and, to a lesser extent, Hungary, while causing a loss of life expectancy in Romania. In the 1990s, improvements in infant mortality continued to make substantial contributions to life expectancy in Lithuania and Hungary but had little impact in either Germany or Romania. Among adults, improvements in amenable mortality continued to benefit Hungarians and west Germans. In Lithuania, up to two-thirds of the gain in temporary life expectancy were attributable to falling mortality from ischaemic heart disease whereas medical care otherwise seems to have had a negative impact. Romanian men and women experienced increases in amenable mortality that contributed up to a half of the overall loss of life expectancy. Our findings suggest that during the last 20 years changes in medical care had considerable impact, positively as well as negatively, on changing mortality in selected central and eastern European countries.

Hospital mortality, length of stay, and preventable complications among critically ill patients before and after tele-ICU reengineering of critical care processes.

CONTEXT The association of an adult tele-intensive care unit (ICU) intervention with hospital mortality, length of stay, best practice adherence, and preventable complications for an academic medical center has not been reported. OBJECTIVE To quantify the association of a tele-ICU intervention with hospital mortality, length of stay, and complications that are preventable by adherence to best practices. DESIGN, SETTING, AND PATIENTS Prospective stepped-wedge clinical practice study of 6290 adults admitted to any of 7 ICUs (3 medical, 3 surgical, and 1 mixed cardiovascular) on 2 campuses of an 834-bed academic medical center that was performed from April 26, 2005, through September 30, 2007. Electronically supported and monitored processes for best practice adherence, care plan creation, and clinician response times to alarms were evaluated. MAIN OUTCOME MEASURES Case-mix and severity-adjusted hospital mortality. Other outcomes included hospital and ICU length of stay, best practice adherence, and complication rates. RESULTS The hospital mortality rate was 13.6% (95% confidence interval [CI], 11.9%-15.4%) during the preintervention period compared with 11.8% (95% CI, 10.9%-12.8%) during the tele-ICU intervention period (adjusted odds ratio [OR], 0.40 [95% CI, 0.31-0.52]). The tele-ICU intervention period compared with the preintervention period was associated with higher rates of best clinical practice adherence for the prevention of deep vein thrombosis (99% vs 85%, respectively; OR, 15.4 [95% CI, 11.3-21.1]) and prevention of stress ulcers (96% vs 83%, respectively; OR, 4.57 [95% CI, 3.91-5.77], best practice adherence for cardiovascular protection (99% vs 80%, respectively; OR, 30.7 [95% CI, 19.3-49.2]), prevention of ventilator-associated pneumonia (52% vs 33%, respectively; OR, 2.20 [95% CI, 1.79-2.70]), lower rates of preventable complications (1.6% vs 13%, respectively, for ventilator-associated pneumonia [OR, 0.15; 95% CI, 0.09-0.23] and 0.6% vs 1.0%, respectively, for catheter-related bloodstream infection [OR, 0.50; 95% CI, 0.27-0.93]), and shorter hospital length of stay (9.8 vs 13.3 days, respectively; hazard ratio for discharge, 1.44 [95% CI, 1.33-1.56]). The results for medical, surgical, and cardiovascular ICUs were similar. CONCLUSION In a single academic medical center study, implementation of a tele-ICU intervention was associated with reduced adjusted odds of mortality and reduced hospital length of stay, as well as with changes in best practice adherence and lower rates of preventable complications.

Older People at the End of Life: Delivery of Care and Needs for Improvement from the Perspective of Bereaved Relatives

BACKGROUND Due to demographic changes with an increasing number of older people with chronic illness and multimorbidity palliative care for geriatric patients has become increasingly important. The aim of this study was to explore the perspective of bereaved relatives with regard to their experiences and expectations concerning the delivery of care for older people in the last phase of life. METHODS Qualitative interviews with 12 relatives of deceased older patients (aged 60 years or older). The interviews were recorded, transcribed, coded and analysed using the approach of qualitative content analysis according to Mayring. RESULTS The bereaved relatives perceived that the care for geriatric patients in the last phase of life was inappropriate in various respects. They criticised overtreatment (e.g. skin cancer diagnostic) as well as unmet needs (e.g. treatment of pain, patient centred care, communication). Family doctors were seen as the primary contact persons in the professional health system. CONCLUSIONS From the perspective of bereaved relatives care for older people in the last phase of life has serious deficits. They criticise an inappropriate priority setting and the disregard of palliative care. There is a need for better communication and information exchange regarding the needs and expectations of patients and relatives, and regarding the targets of treatment. Therefore it may be helpful to use advance directives more intensively. Furthermore, it seems to be necessary to strengthen generalist palliative care particularly delivered by family doctors and community nurses.

Anxiety

OBJECTIVES To examine the effect of routinely administered psychiatric questionnaires on the recognition, management, and outcome of psychiatric disorders in non-psychiatric settings. DATA SOURCES Embase, Medline, PsycLIT, Cinahl, Cochrane Controlled Trials Register, and hand searches of key journals. METHODS A systematic review of randomised controlled trials of the administration and routine feedback of psychiatric screening and outcome questionnaires to clinicians in non-psychiatric settings. Narrative overview of key design features and end points, together with a random effects quantitative synthesis of comparable studies. MAIN OUTCOME MEASURES Recognition of psychiatric disorders after feedback of questionnaire results; interventions for psychiatric disorders; and outcome of psychiatric disorders. RESULTS Nine randomised studies were identified that examined the use of common psychiatric instruments in primary care and general hospital settings. Studies compared the effect of the administration of these instruments followed by the feedback of the results to clinicians, with administration with no feedback. Meta-analytic pooling was possible for four of these studies (2457 participants), which measured the effect of feedback on the recognition of depressive disorders. Routine administration and feedback of scores for all patients (irrespective of score) did not increase the overall rate of recognition of mental disorders such as anxiety and depression (relative risk of detection of depression by clinician after feedback 0.95, 95% confidence interval 0.83 to 1.09). Two studies showed that routine administration followed by selective feedback for only high scorers increased the rate of recognition of depression (relative risk of detection of depression after feedback 2.64, 1.62 to 4.31). This increased recognition, however, did not translate into an increased rate of intervention. Overall, studies of routine administration of psychiatric measures did not show an effect on patient outcome. CONCLUSIONS The routine measurement of outcome is a costly exercise. Little evidence shows that it is of benefit in improving psychosocial outcomes of those with psychiatric disorder managed in non-psychiatric settings.

Time and Money: The True Costs of Health Care Utilization for Patients Receiving "Free" HIV/Tuberculosis Care and Treatment in Rural KwaZulu-Natal.

BACKGROUND HIV and tuberculosis (TB) services are provided free of charge in many sub-Saharan African countries, but patients still incur costs. METHODS Patient-exit interviews were conducted in primary health care clinics in rural South Africa with representative samples of 200 HIV-infected patients enrolled in a pre-antiretroviral treatment (pre-ART) program, 300 patients receiving antiretroviral treatment (ART), and 300 patients receiving TB treatment. For each group, we calculated health expenditures across different spending categories, time spent traveling to and using services, and how patients financed their spending. Associations between patient group and costs were assessed in multivariate regression models. RESULTS Total monthly health expenditures [1 USD = 7.3 South African Rand (ZAR)] were ZAR 171 [95% confidence interval (CI): 134 to 207] for pre-ART, ZAR 164 (95% CI: 141 to 187) for ART, and ZAR 122 (95% CI: 105 to 140) for TB patients (P = 0.01). Total monthly time costs (in hours) were 3.4 (95% CI: 3.3 to 3.5) for pre-ART, 5.0 (95% CI: 4.7 to 5.3) for ART, and 3.2 (95% CI: 2.9 to 3.4) for TB patients (P < 0.01). Although overall patient costs were similar across groups, pre-ART patients spent on average ZAR 29.2 more on traditional healers and ZAR 25.9 more on chemists and private doctors than ART patients, whereas ART patients spent ZAR 34.0 more than pre-ART patients on transport to clinics (P < 0.05 for all results). Thirty-one percent of pre-ART, 39% of ART, and 41% of TB patients borrowed money or sold assets to finance health care. CONCLUSIONS Patients receiving nominally free care for HIV/TB face large private costs, commonly leading to financial distress. Subsidized transport, fewer clinic visits, and drug pick-up points closer to home could reduce costs for ART patients, potentially improving retention and adherence. Large expenditure on alternative care among pre-ART patients suggests that transitioning patients to ART earlier, as under HIV treatment-as-prevention policies, may not substantially increase patients' financial burden.

A systematic review of parent and clinician views and perceptions that influence prescribing decisions in relation to acute childhood infections in primary care

OBJECTIVES To investigate the views of parents, clinicians, and children pertaining to prescribing decisions for acute childhood infection in primary care. METHODS A systematic review of qualitative studies. Meta-ethnographic methods were used, with data drawn from the primary studies in an interpretive analysis. RESULTS A total of 15 studies met the inclusion criteria. The literature was dominated by concerns about antibiotic over-prescription. Children's views were not reported. Clinicians prescribed antibiotics when they felt pressured by parents or others (e.g. employers) to do so, when they believed there was a clear clinical indication, but also when they felt uncertain of clinical or social outcomes they prescribed "just in case". Parents wanted antibiotics when they felt they would improve the current illness, and when they felt pressure from daycare providers or employers. Clinicians avoided antibiotics when they were concerned about adverse reactions or drug resistance, when certain they were not indicated, and when there was no perceived pressure from parents. Parents also wished to avoid adverse effects of antibiotics, and did not want antibiotics when they would not relieve current symptoms. Some parents preferred to avoid medication altogether. Within paediatric consultations, parents sought a medical evaluation and decision. Primary care clinicians want satisfied parents and short consultations. CONCLUSIONS Antibiotic prescriptions for childhood infections in primary care often result from "just in case" prescribing. These findings suggest that interventions which reduce clinician uncertainty regarding social or clinical outcomes and provide strategies to meet parents' needs within a short consultation are most likely to reduce antibiotic prescribing.

Comparisons of patient and physician expectations for cancer survivorship care.

PURPOSE To compare expectations for cancer survivorship care between patients and their physicians and between primary care providers (PCPs) and oncologists. METHODS Survivors and their physicians were surveyed to evaluate for expectations regarding physician participation in primary cancer follow-up, screening for other cancers, general preventive health, and management of comorbidities. RESULTS Of 992 eligible survivors and 607 physicians surveyed, 535 (54%) and 378 (62%) were assessable, respectively. Among physician respondents, 255 (67%) were PCPs and 123 (33%) were oncologists. Comparing patients with their oncologists, expectations were highly discrepant for screening for cancers other than the index one (agreement rate, 29%), with patients anticipating significantly more oncologist involvement. Between patients and their PCPs, expectations were most incongruent for primary cancer follow-up (agreement rate, 35%), with PCPs indicating they should contribute a much greater part to this aspect of care. Expectations between patients and their PCPs were generally more concordant than between patients and their oncologists. PCPs and oncologists showed high discordances in perceptions of their own roles for primary cancer follow-up, cancer screening, and general preventive health (agreement rates of 3%, 44%, and 51%, respectively). In the case of primary cancer follow-up, both PCPs and oncologists indicated they should carry substantial responsibility for this task. CONCLUSION Patients and physicians have discordant expectations with respect to the roles of PCPs and oncologists in cancer survivorship care. Uncertainties around physician roles and responsibilities can lead to deficiencies in care, supporting the need to make survivorship care planning a standard component in cancer management.

Unmet need for mental health care among U.S. children: variation by ethnicity and insurance status.

OBJECTIVE Policy discussions regarding the mental health needs of children and adolescents emphasize a lack of use of mental health services among youth, but few national estimates are available. The authors use three national data sets and examine ethnic disparities in unmet need (defined as having a need for mental health evaluation but not using any services in a 1-year period) to provide such estimates. METHOD The authors conducted secondary data analyses in three nationally representative household surveys fielded in 1996-1998: the National Health Interview Survey, the National Survey of American Families, and the Community Tracking Survey. They determined rates of mental health service use by children and adolescents 3-17 years of age and differences by ethnicity and insurance status. Among the children defined as in need of mental health services, defined by an estimator of mental health problems (selected items from the Child Behavior Checklist), they examined the association of unmet need with ethnicity and insurance status. RESULTS In a 12-month period, 2%-3% of children 3-5 years old and 6%-9% of children and adolescents 6-17 years old used mental health services. Of children and adolescents 6-17 years old who were defined as needing mental health services, nearly 80% did not receive mental health care. Controlling for other factors, the authors determined that the rate of unmet need was greater among Latino than white children and among uninsured than publicly insured children. CONCLUSIONS These findings reveal that most children who need a mental health evaluation do not receive services and that Latinos and the uninsured have especially high rates of unmet need relative to other children. Rates of use of mental health services are extremely low among preschool children. Research clarifying the reasons for high rates of unmet need in specific groups can help inform policy and clinical programs.

Ethnographic study of incidence and severity of intravenous drug errors.

OBJECTIVES To determine the incidence and clinical importance of errors in the preparation and administration of intravenous drugs and the stages of the process in which errors occur. DESIGN Prospective ethnographic study using disguised observation. PARTICIPANTS Nurses who prepared and administered intravenous drugs. SETTING 10 wards in a teaching and non-teaching hospital in the United Kingdom. MAIN OUTCOME MEASURES Number, type, and clinical importance of errors. RESULTS 249 errors were identified. At least one error occurred in 212 out of 430 intravenous drug doses (49%, 95% confidence interval 45% to 54%). Three doses (1%) had potentially severe errors, 126 (29%) potentially moderate errors, and 83 (19%) potentially minor errors. Most errors occurred when giving bolus doses or making up drugs that required multiple step preparation. CONCLUSIONS The rate of intravenous drug errors was high. Although most errors would cause only short term adverse effects, a few could have been serious. A combination of reducing the amount of preparation on the ward, training, and technology to administer slow bolus doses would probably have the greatest effect on error rates.

Angina with "normal" coronary arteries: sex differences in outcomes.

BACKGROUND Several studies have demonstrated that women with nonobstructive coronary disease have a high rate of subsequent investigations, rehospitalizations for recurrent chest pain, and repeat coronary angiography. The sex specificity of this finding is unclear. We therefore undertook an evaluation of sex differences in rehospitalization for acute coronary syndrome (ACS) or chest pain in patients with "angiographically normal" coronaries. METHODS A retrospective cohort study using prospectively collected angiographic and clinical data on all patients in British Columbia, Canada, presenting for their first cardiac catheterization with suspected ischemic heart disease but angiographically normal coronaries. RESULTS Among 32,856 patients, 7.1% of men versus 23.3% of women were angiographically normal (P < .001). Among angiographically normal patients, women were older and more likely to present with hypertension, prior stroke, chronic obstructive pulmonary disease, and peripheral vascular disease than men, but Canadian Cardiovascular Society class of angina did not vary by sex. Within 1 year, 1.0% died, (19 women, 18 men, P = .27) and 0.6% had a stroke (13 women, 9 men, P = .91). Readmission to hospital for ACS or chest pain requiring catheterization was significantly higher in women compared to men (adjusted OR 4.06; 95% CI 1.15-14.31). CONCLUSIONS In a contemporary, population-based cohort presenting for cardiac catheterization for suspected ischemia, women with angiographically normal coronaries were >4 times more likely to be readmitted to hospital for ACS/chest pain within 180 days compared to men. The observed sex difference has important social and economic implications and suggests that traditional diagnostic methods may not be optimal for women.

To err is human. Building a safer health system

Human beings, make errors Healthcare Services is a complex industry prone to accidents. The IOM Report [1] points out that some systems are more prone to accidents than others. When a system fails there are often multiple faults. In healthcare,human errors are the greatest contributors to accidents,however when human error is to blame it often depends upon failures within the system. These failures exists in the system before the error occurs, the same as with latent errors which are difficult to identify since they may be hidden in computers or within the various managerial layers. Most of the errors can be prevented by designing systems that make it hard for people to do the wrong thing and easy for people to do the right thing. In healthcare, this means designing processes that are able to ensure that patients are safe from accidental injury. As healthcare and the system that delivers it become more complex, the opportunities for errors abound. The IOM report “To Err is Human” proposes an approach for reducing medical errors and improving patient safety. The environment within which this occurs has a critical influence on quality. This influence may contain two dimensions; the first consists of the domain of quality which includes the practice that is consistent with current medical knowledge. The second dimension consists of forces in the external environment that can drive quality improvement in the delivery system. Although the risk of dying as a result of a medical error, far surpasses the risk of dying in an airline accident, public attention has been more focused on improving safety in the airline industry than in healthcare systems. Because of the absence of standardized nomenclature, it is important to define what an error is and what is an adverse event, the IOM Report defines them in the following way: “An error is the failure of a planned action to be completed as intended or the use of a wrong plan to achieve an aim. ” An adverse event is an injury caused by medical management rather than the underlying condition of the patient. An adverse event attributable to error is a “preventable adverse event”.

Immunophenotypic analysis of AIDS-related diffuse large B-cell lymphoma and clinical implications in patients from AIDS malignancies consortium clinical trials 010 and 034

PURPOSE Diffuse large B-cell lymphoma (DLBCL) represents a clinically heterogeneous disease. Models based on immunohistochemistry predict clinical outcome. These include subdivision into germinal center (GC) versus non-GC subtypes; proliferation index (measured by expression of Ki-67), and expression of BCL-2, FOXP1, or B-lymphocyte-induced maturation protein (Blimp-1)/PRDM1. We sought to determine whether immunohistochemical analyses of biopsies from patients with DLBCL having HIV infection are similarly relevant for prognosis. PATIENTS AND METHODS We examined 81 DLBCLs from patients with AIDS in AMC010 (cyclophosphamide, doxorubicin, vincristine, and prednisone [CHOP] v CHOP-rituximab) and AMC034 (etoposide, doxorubicin, vincristine, prednisone, and dose-adjusted cyclophosphamide plus rituximab concurrent v sequential) clinical trials and compared the immunophenotype with survival data, Epstein-Barr virus (EBV) positivity, and CD4 counts. RESULTS The GC and non-GC subtypes of DLBCL did not differ significantly with respect to overall survival or CD4 count at cancer presentation. EBV could be found in both subtypes of DLBCL, although less frequently in the GC subtype, and did not affect survival. Expression of FOXP1, Blimp-1/PRDM1, or BCL-2 was not correlated with the outcome in patients with AIDS-related DLBCL. CONCLUSION These data indicate that with current treatment strategies for lymphoma and control of HIV infection, commonly used immunohistochemical markers may not be clinically relevant in HIV-infected patients with DLBCL. The only predictive immunohistochemical marker was found to be Ki-67, where a higher proliferation index was associated with better survival, suggesting a better response to therapy in patients whose tumors had higher proliferation rates.

Comparative Safety of Targeted Therapies for Metastatic Colorectal Cancer between Elderly and Younger Patients: a Study Using the International Pharmacovigilance Database

Metastatic colorectal cancer (mCRC) is increasingly treated using targeted therapies. Post-marketing safety of these agents is understudied, especially in the elderly. This study aimed to compare, according to age, the adverse drug reactions (ADRs) of targeted therapies used for mCRC in real life. An extraction of VigiBase, which contains World Health Organization individual case safety reports (ICSRs), was performed. All ADR reports with aflibercept, bevacizumab, cetuximab, panitumumab, or regorafenib used in CRC were considered. For all drugs, chi-square tests were used to compare frequencies of serious ADRs between patients aged ≥75 and <75 years. For selected ADRs and each drug, the drug-ADR association compared to other anticancer drugs was estimated through the proportional reporting ratio (PRR) in both age groups. There were 21,565 ICSRs included, among which 74% were serious and 11% were fatal. Median age was 64 years (Inter Quartile Range = 56–71) and 15% of patients were aged ≥75; 57% were male. Serious ICSRs accounted for 47,292 ADRs. Neutropenia was not more reported in elderly for all drugs while diarrhea was more reported in elderly for panitumumab. Cardiac disorders were more reported in elderly patients, in particular heart failure, especially for bevacizumab, cetuximab, and regorafenib, as were respiratory, thoracic, and mediastinal disorders. Most of PRR were not different between the two groups, except encephalopathies, which were significantly associated with bevacizumab in the elderly only. ADRs related to targeted therapies used for mCRC treatment were different across age groups; yet, not systematically more reported or worse in elderly patients. Selected elderly patients could, therefore, be treated with these targeted therapies.

Mortality from causes amenable and non-amenable to medical care: the experience of eastern Europe.

OBJECTIVE To investigate comparative national trends in mortality from conditions amenable to timely, appropriate medical care and from those considered not to be amenable to such care. DESIGN Analysis of trends in direct age standardised mortality from the 1950s to 1987. SETTING Four eastern European nations (Hungary, Czechoslovakia, Poland, the German Democratic Republic) and two western European (the Federal Republic of Germany and England and Wales) and two North American nations (United States and Canada). SUBJECTS The total populations of the relevant countries during the period examined. MAIN OUTCOME MEASURES Proportional changes over time in age standardised mortality. Mortality from amenable and non-amenable causes was restricted to the age group 0-64. RESULTS A divergence in the trends for all cause mortality between eastern Europe and the western nations occurred in about 1970, when the rates in western countries steadily declined but those in eastern Europe remained fairly static. In the age group 0-64 mortality from causes considered amenable to medical care fell less quickly in eastern Europe than in the West, particularly after 1970. In the same age group, mortality from non-amenable causes rose in eastern European countries from the late 1960s compared with substantial declines in such mortality in the West. CONCLUSIONS Non-amenable causes of death seem to be the principal, but not exclusive, reason for lack of improvement in trends in all cause mortality in eastern Europe from 1970. The agenda for action in eastern Europe should give priority to a healthier lifestyle and improvement of the environment though not neglect enhancements in the quality and efficiency of direct health services.

Knowledge and Practice of Standard Precautions and Awareness Regarding Post-Exposure Prophylaxis for HIV among Interns of a Medical College in West Bengal, India.

OBJECTIVES To assess the knowledge of interns on standard precautions and post-exposure prophylaxis for HIV, and identify the gap between knowledge and practice relating to standard precautions, as well as determining the perceived barriers against adherence to standard precautions. METHODS The study was conducted on 130 interns of 2010-11 batch from a government-run medical college in Kolkata, India. All participants completed a self-administered questionnaire with items relating to basic components of standard precautions and post-exposure prophylaxis for HIV. The questionnaire also included open ended questions relating to reasons for non-adherence to the practice of standard precautions along with additional space for specific comments, if any. RESULTS Poor adherence in the use of personal protective equipment, hand washing, safe handling and disposal of needles and sharp objects were found to be among the practices for which the interns expressed correct knowledge. While the main reasons for non-adherence were found to be clumsiness in handling needles, wearing gloves, feeling uncomfortable when wearing aprons, impracticality of regular hand-washing and non-availability of equipment. Although the majority of the respondents (84.6%) expressed awareness of washing sites of injured with soap and water, approximately 32.3% did not know that antiseptics could cause more damage. Also, only 63.8% expressed awareness of reporting any incidence of occupational exposure, while knowledge on post-exposure prophylaxis regimens was generally found to be poor. CONCLUSION The considerable gap between knowledge and practice of standard precautions and inadequate knowledge of post-exposure prophylaxis emphasizes the need for continuous onsite training of interns with supportive supervision and monitoring of their activities.

Use of health services by prison inmates: comparisons with the community.

The future organisation of prison health care 1 recommends that the NHS and the Prison Service work together to plan and provide health care services for prisoners. Whereas previously the Prison Service had this responsibility alone. The NHS will therefore have to take stock of the current level at which prison health care is demanded and provided. A key part of the information base for joint planning therefore includes data on current service utilisation. This paper compares primary care and inpatient health service utilisation data for UK prisoners with health services utilisation data for equivalent community populations. In the community, primary care is provided principally by general practitioners and professions allied to medicine (mostly nurses). Residents in the community have access to the full range of NHS outpatient and inpatient facilities. Within prisons, primary care is provided by medical officers (some of whom are general practitioners), nursing grades and health care officers (who have received some training in health care). Some prisons have their own inpatient facilities (health care centre beds). These provide a low level of inpatient care and do not have a direct equivalent in the community. Prisoners also have access to NHS outpatient and inpatient facilities and to visiting specialists. The prison population has a high turnover and varies from day to day. Because of this, the prison population is expressed as an average daily population during a one year period. …

The effectiveness of right heart catheterization in the initial care of critically ill patients. SUPPORT Investigators.

OBJECTIVE To examine the association between the use of right heart catheterization (RHC) during the first 24 hours of care in the intensive care unit (ICU) and subsequent survival, length of stay, intensity of care, and cost of care. DESIGN Prospective cohort study. SETTING Five US teaching hospitals between 1989 and 1994. SUBJECTS A total of 5735 critically ill adult patients receiving care in an ICU for 1 of 9 prespecified disease categories. MAIN OUTCOME MEASURES Survival time, cost of care, intensity of care, and length of stay in the ICU and hospital, determined from the clinical record and from the National Death Index. A propensity score for RHC was constructed using multivariable logistic regression. Case-matching and multivariable regression modeling techniques were used to estimate the association of RHC with specific outcomes after adjusting for treatment selection using the propensity score. Sensitivity analysis was used to estimate the potential effect of an unidentified or missing covariate on the results. RESULTS By case-matching analysis, patients with RHC had an increased 30-day mortality (odds ratio, 1.24; 95% confidence interval, 1.03-1.49). The mean cost (25th, 50th, 75th percentiles) per hospital stay was $49 300 ($17 000, $30 500, $56 600) with RHC and $35 700 ($11 300, $20 600, $39 200) without RHC. Mean length of stay in the ICU was 14.8 (5, 9, 17) days with RHC and 13.0 (4, 7, 14) days without RHC. These findings were all confirmed by multivariable modeling techniques. Subgroup analysis did not reveal any patient group or site for which RHC was associated with improved outcomes. Patients with higher baseline probability of surviving 2 months had the highest relative risk of death following RHC. Sensitivity analysis suggested that a missing covariate would have to increase the risk of death 6-fold and the risk of RHC 6-fold for a true beneficial effect of RHC to be misrepresented as harmful. CONCLUSION In this observational study of critically ill patients, after adjustment for treatment selection bias, RHC was associated with increased mortality and increased utilization of resources. The cause of this apparent lack of benefit is unclear. The results of this analysis should be confirmed in other observational studies. These findings justify reconsideration of a randomized controlled trial of RHC and may guide patient selection for such a study.

Validity and reliability of observational methods for studying medication administration errors.

The validity and reliability of observational methods for studying medication administration errors (MAEs) were studied. Between January and June 1998, two pharmacists observed consecutive drug administration rounds by nurses on two wards in a U.K. hospital and recorded all MAEs identified. The observers intervened in cases of potentially harmful errors. MAE records were audited to determine the percentage of omitted doses for which a corresponding reason was documented for the observation periods and for nonobservation periods. Error rates for each drug administration round were analyzed according to whether they were for the nurse's first, second, third (and so on) observed round. Error rates were calculated before and after the first intervention with nurses for whom an intervention was made. Observer reliability was calculated by comparing the rates of errors identified by the two observers. There was no difference between the observation and nonobservation periods in the percentage of omitted doses for which a reason was documented, and there was no change in the error rate with repeated observations. There was no difference in error rates before and after the first intervention for each nurse. There was also no difference in error detection between the two observers and no change with increasing duration of observation. Observation of nurses during drug administration at a U.K. hospital did not significantly affect the MAE rate; nor did tactful interventions by the observers. Observer reliability was high. Concerns about the validity and reliability of observational methods for identifying MAEs may be unfounded.

The financial cost of doctors emigrating from sub-Saharan Africa: human capital analysis

OBJECTIVE To estimate the lost investment of domestically educated doctors migrating from sub-Saharan African countries to Australia, Canada, the United Kingdom, and the United States. DESIGN Human capital cost analysis using publicly accessible data. SETTINGS Sub-Saharan African countries. PARTICIPANTS Nine sub-Saharan African countries with an HIV prevalence of 5% or greater or with more than one million people with HIV/AIDS and with at least one medical school (Ethiopia, Kenya, Malawi, Nigeria, South Africa, Tanzania, Uganda, Zambia, and Zimbabwe), and data available on the number of doctors practising in destination countries. MAIN OUTCOME MEASURES The financial cost of educating a doctor (through primary, secondary, and medical school), assuming that migration occurred after graduation, using current country specific interest rates for savings converted to US dollars; cost according to the number of source country doctors currently working in the destination countries; and savings to destination countries of receiving trained doctors. RESULTS In the nine source countries the estimated government subsidised cost of a doctor's education ranged from $21,000 (£13,000; €15,000) in Uganda to $58,700 in South Africa. The overall estimated loss of returns from investment for all doctors currently working in the destination countries was $2.17bn (95% confidence interval 2.13bn to 2.21bn), with costs for each country ranging from $2.16m (1.55m to 2.78m) for Malawi to $1.41bn (1.38bn to 1.44bn) for South Africa. The ratio of the estimated compounded lost investment over gross domestic product showed that Zimbabwe and South Africa had the largest losses. The benefit to destination countries of recruiting trained doctors was largest for the United Kingdom ($2.7bn) and United States ($846m). CONCLUSIONS Among sub-Saharan African countries most affected by HIV/AIDS, lost investment from the emigration of doctors is considerable. Destination countries should consider investing in measurable training for source countries and strengthening of their health systems.

Computer assisted learning in undergraduate medical education.

It is becoming “a truth universally acknowledged” that the education of undergraduate medical students will be enhanced through the use of computer assisted learning. Access to the wide range of online options illustrated in the figure must surely make learning more exciting, effective, and likely to be retained. This assumption is potentially but by no means inevitably correct. ### Box 1: Why fund computer assisted learning? Computer assisted learning is inevitable —Individual lecturers and departments are already beginning to introduce a wide range of computer based applications, sometimes in a haphazard way. Planned and coordinated development is better than indiscriminate expansion  It is convenient and flexible —Courses supported by computer assisted learning applications may require fewer face to face lectures and seminars and place fewer geographical and temporal constraints on staff and students. Students at peripheral hospitals or primary care centres may benefit in particular  Unique presentational benefits —Computer presentation is particularly suited to subjects that are visually intensive, detail oriented, and difficult to conceptualise, such as complex biochemical processes or microscopic images.1 Furthermore, “virtual” cases may reduce the need to use animal or human tissue in learning  Personalised learning —Each learner can progress at his or her preferred pace. They can repeat, interrupt, and resume at will, which may have particular advantages for weaker students  Economies of scale —Once an application has been set up, the incremental cost of offering it to additional students is relatively small  Competitive advantage —Potential applicants may use the quality of information technology to discriminate between medical schools. A “leading edge” virtual campus is likely to attract good students  Achieves the ultimate goal of higher education —The goal is to link people into learning communities. Computer applications, especially the internet and world wide web, are an extremely efficient way of doing this2  Expands pedagogical horizons —The most controversial argument for … RETURN TO TEXT

Incidence of adverse drug events and potential adverse drug events. Implications for prevention. ADE Prevention Study Group.

OBJECTIVES To assess incidence and preventability of adverse drug events (ADEs) and potential ADEs. To analyze preventable events to develop prevention strategies. DESIGN Prospective cohort study. PARTICIPANTS All 4031 adult admissions to a stratified random sample of 11 medical and surgical units in two tertiary care hospitals over a 6-month period. Units included two medical and three surgical intensive care units and four medical and two surgical general care units. MAIN OUTCOME MEASURES Adverse drug events and potential ADEs. METHODS Incidents were detected by stimulated self-report by nurses and pharmacists and by daily review of all charts by nurse investigators. Incidents were subsequently classified by two independent reviewers as to whether they represented ADEs or potential ADEs and as to severity and preventability. RESULTS Over 6 months, 247 ADEs and 194 potential ADEs were identified. Extrapolated event rates were 6.5 ADEs and 5.5 potential ADEs per 100 nonobstetrical admissions, for mean numbers per hospital per year of approximately 1900 ADEs and 1600 potential ADEs. Of all ADEs, 1% were fatal (none preventable), 12% life-threatening, 30% serious, and 57% significant. Twenty-eight percent were judged preventable. Of the life-threatening and serious ADEs, 42% were preventable, compared with 18% of significant ADEs. Errors resulting in preventable ADEs occurred most often at the stages of ordering (56%) and administration (34%); transcription (6%) and dispensing errors (4%) were less common. Errors were much more likely to be intercepted if the error occurred earlier in the process: 48% at the ordering stage vs 0% at the administration stage. CONCLUSION Adverse drug events were common and often preventable; serious ADEs were more likely to be preventable. Most resulted from errors at the ordering stage, but many also occurred at the administration stage. Prevention strategies should target both stages of the drug delivery process.

Validating a conceptual model for an inter-professional approach to shared decision making: a mixed methods study

RATIONALE, AIMS AND OBJECTIVES Following increased interest in having inter-professional (IP) health care teams engage patients in decision making, we developed a conceptual model for an IP approach to shared decision making (SDM) in primary care. We assessed the validity of the model with stakeholders in Canada. METHODS In 15 individual interviews and 7 group interviews with 79 stakeholders, we asked them to: (1) propose changes to the IP-SDM model; (2) identify barriers and facilitators to the model's implementation in clinical practice; and (3) assess the model using a theory appraisal questionnaire. We performed a thematic analysis of the transcripts and a descriptive analysis of the questionnaires. RESULTS Stakeholders suggested placing the patient at its centre; extending the concept of family to include significant others; clarifying outcomes; highlighting the concept of time; merging the micro, meso and macro levels in one figure; and recognizing the influence of the environment and emotions. The most common barriers identified were time constraints, insufficient resources and an imbalance of power among health professionals. The most common facilitators were education and training in inter-professionalism and SDM, motivation to achieve an IP approach to SDM, and mutual knowledge and understanding of disciplinary roles. Most stakeholders considered that the concepts and relationships between the concepts were clear and rated the model as logical, testable, having clear schematic representation, and being relevant to inter-professional collaboration, SDM and primary care. CONCLUSIONS Stakeholders validated the new IP-SDM model for primary care settings and proposed few modifications. Future research should assess if the model helps implement SDM in IP clinical practice.

Prolonged conservative care versus early surgery in patients with sciatica caused by lumbar disc herniation: two year results of a randomised controlled trial.

OBJECTIVES To evaluate the effects of early lumbar disc surgery compared with prolonged conservative care for patients with sciatica over two years of follow-up. DESIGN Randomised controlled trial. SETTING Nine Dutch hospitals. PARTICIPANTS 283 patients with 6-12 weeks of sciatica. INTERVENTIONS Early surgery or an intended six months of continued conservative treatment, with delayed surgery if needed. MAIN OUTCOME MEASURES Scores from Roland disability questionnaire for sciatica, visual analogue scale for leg pain, and Likert self rating scale of global perceived recovery. RESULTS Of the 141 patients assigned to undergo early surgery, 125 (89%) underwent microdiscectomy. Of the 142 patients assigned to conservative treatment, 62 (44%) eventually required surgery, seven doing so in the second year of follow-up. There was no significant overall difference between treatment arms in disability scores during the first two years (P=0.25). Improvement in leg pain was faster for patients randomised to early surgery, with a significant difference between "areas under the curves" over two years (P=0.05). This short term benefit of early surgery was no longer significant by six months and continued to narrow between six months and 24 months. Patient satisfaction decreased slightly between one and two years for both groups. At two years 20% of all patients reported an unsatisfactory outcome. CONCLUSIONS Early surgery achieved more rapid relief of sciatica than conservative care, but outcomes were similar by one year and these did not change during the second year. TRIAL REGISTRY ISRCT No 26872154.

Apolipoprotein E4 as a predictor of outcomes in pediatric mild traumatic brain injury.

The epsilon4 allele of the apolipoprotein E (APOE) gene has been linked to negative outcomes among adults with traumatic brain injury (TBI) across the spectrum of severity, with preliminary evidence suggesting a similar pattern among children. This study investigated the relationship of the APOE epsilon4 allele to outcomes in children with mild TBI. Participants in this prospective, longitudinal study included 99 children with mild TBI between the ages of 8 and 15 recruited from consecutive admissions to Emergency Departments at two large children's hospitals. Outcomes were assessed acutely in the Emergency Department and at follow-ups at 2 weeks, 3 months, and 12 months post-injury. Among the 99 participants, 28 had at least one epsilon4 allele. Children with and without an epsilon4 allele did not differ demographically. Children with an epsilon4 allele were significantly more likely than those without an epsilon4 allele to have a Glasgow Coma Scale score of less than 15, but the groups did not differ on any other measures of injury severity. Those with an epsilon4 allele exhibited better performance than children without an epsilon4 allele on a test of constructional skill, but the groups did not differ on any other neuropsychological tests. Children with and without an epsilon4 allele also did not differ on measures of post-concussive symptoms. Overall, the findings suggest that the APOE epsilon4 allele is not consistently related to the outcomes of mild TBI in children.

Socioeconomic factors, material inequalities, and perceived control in self-rated health: cross-sectional data from seven post-communist countries.

This study examined the association between perceived control and several socioeconomic variables and self-rated health in seven post-communist countries (Russia, Estonia, Lithuania, Latvia, Hungary, Poland, Czech Republic). Questionnaire interviews were used to collect data on self-rated health in the last 12 months, education, marital status, perceived control based on nine questions, and material deprivation based on availability of food, clothing and heating. For each population, two ecological measures of material inequalities were available: an inequality score estimated from the survey data as the distance between the 90th and 10th percentiles of material deprivation, and Gini coefficient from published sources. Data on 5330 men and women aged 20-60 were analysed. Prevalence of poor health (worse than average) varied between 8% in Czechs and 19% in Hungarians. The age-sex-adjusted odds ratio for university vs primary education was 0.36 (0.26-0.49); odds ratios per 1 standard deviation increase in perceived control and in material deprivation were 0.58 (95% CI 0.48-0.69) and 1.51 (1.40-1.63), respectively. The odds ratio for an increase in inequality equivalent to the difference between the most and the least unequal populations was 1.49 (0.88-2.52) using the material inequality score and 1.41 (0.91-2.20) using the Gini coefficient. No indication of an effect of either inequality measure was seen after adjustment for individuals' deprivation or perceived control. The results suggest that, as in western populations, education and material deprivation are strongly related to self-rated health. Perceived control appeared statistically to mediate some of the effects of material deprivation. The non-significant effects of both ecological measures of inequality were eliminated by controlling for individuals' characteristics.

Staphylococcus aureus infection dynamics

Staphylococcus aureus is a human commensal that can also cause systemic infections. This transition requires evasion of the immune response and the ability to exploit different niches within the host. However, the disease mechanisms and the dominant immune mediators against infection are poorly understood. Previously it has been shown that the infecting S. aureus population goes through a population bottleneck, from which very few bacteria escape to establish the abscesses that are characteristic of many infections. Here we examine the host factors underlying the population bottleneck and subsequent clonal expansion in S. aureus infection models, to identify underpinning principles of infection. The bottleneck is a common feature between models and is independent of S. aureus strain. Interestingly, the high doses of S. aureus required for the widely used "survival" model results in a reduced population bottleneck, suggesting that host defences have been simply overloaded. This brings into question the applicability of the survival model. Depletion of immune mediators revealed key breakpoints and the dynamics of systemic infection. Loss of macrophages, including the liver Kupffer cells, led to increased sensitivity to infection as expected but also loss of the population bottleneck and the spread to other organs still occurred. Conversely, neutrophil depletion led to greater susceptibility to disease but with a concomitant maintenance of the bottleneck and lack of systemic spread. We also used a novel microscopy approach to examine abscess architecture and distribution within organs. From these observations we developed a conceptual model for S. aureus disease from initial infection to mature abscess. This work highlights the need to understand the complexities of the infectious process to be able to assign functions for host and bacterial components, and why S. aureus disease requires a seemingly high infectious dose and how interventions such as a vaccine may be more rationally developed.

Involving family members in cancer care: focus group considerations of patients and oncological providers.

Family members are an integral part of a patient's cancer care from the moment the diagnosis is delivered to the conclusion of treatment. Family members bring with them a range of emotional reactions, interpersonal dynamics and expectations for the care the patient receives. This study is part of a multi-institutional project to continue to improve the process of cancer care. In this study, 19 focus groups (11 patient and 8 provider) were conducted concerning issues related to doctor-patient communication in eight cancer centers in the United States. The content of the conversations was analyzed and thematic categories emerged that highlight the various strengths and difficulties associated with family involvement. The focus groups' comments support the need for explicit conversations between professional caregivers, patients and their loved ones, in order to negotiate the expectations and needs of each team member. Implications for clinical practice and strategies for working with family members are offered.

Influence of antidepressant therapy on sick leave in primary care: ADAS, a comparative observational study

Background Compared to other European countries, Sweden's yearly sick leave expenditures are moderate. Common mental disorders (CMD) are important causes of sick leave, affecting 10-15% of the adult population. A Swedish register based study indicates that antidepressant therapy for patients on long-term sick leave for CMD leads to longer sick leave and higher frequency of non-time-limited sickness compensation as compared to psychotherapy, work oriented rehabilitation, and other therapies. Aim To verify if patients on antidepressant therapy and on long-term sick leave for depression, anxiety and stress-related mental disorders have a longer sick leave than patients treated with other therapies. Method Prospective, observational study at 28 primary health care centers in the Region Västra Götaland, Sweden, including 192 patients on sick leave for CMD. Outcome measures were gross and net sick leave days. Interpretation There were no significant differences in sick leave days (gross or net) due to CMD when comparing the patients treated and not treated with antidepressants during the 12 month observation period. The groups differed at baseline only concerning frequency of exhaustion disorder, with a higher frequency of exhaustion disorder in the group without antidepressants. Analysis of other possible factors associated with shorter or longer sick leave only showed associations with the patient's own perception of possibility of returning to work in near and distant future. An important factor associated with longer sick leave was the patient's own perception of possibility of return to present workplace. As CMD are important causes of sick leave and sick leave costs, this factor should be highlighted in future research on the rehabilitation process.

Mortality risk in patients with dementia treated with antipsychotics versus other psychiatric medications.

OBJECTIVE Mortality rates in the year following new antipsychotic medication starts for neuropsychiatric symptoms of dementia were compared with rates after starts of other psychiatric medications. METHOD The retrospective, cohort study used national data from the Department of Veterans Affairs (fiscal years 2001-2005) on patients older than 65 years who began outpatient treatment with psychiatric medication following a dementia diagnosis (N=10,615). Twelve-month mortality rates were compared in patients taking antipsychotics and those taking other psychiatric medications. The authors controlled for confounding by using multivariate models and propensity-scoring methods. Secondary analyses included a no-medication group and examination of mortality causes. RESULTS All groups taking antipsychotics had significantly higher mortality rates (22.6%-29.1%) than patients taking nonantipsychotic medications (14.6%). Adjusted mortality risks for atypicals and for combined atypical and conventional antipsychotics were similar to those for conventional antipsychotics. The mortality risk was significantly lower for nonantipsychotic medications than conventional antipsychotics. Except for anticonvulsants, the adjusted risks for all individual classes of nonantipsychotics were significantly lower than the risk for antipsychotics. Mortality risks did not change over 12 months. The proportions of patients taking antipsychotics who died from cerebrovascular, cardiovascular, or infectious causes were not higher than rates for those taking nonantipsychotic psychiatric medications. CONCLUSIONS Antipsychotic medications taken by patients with dementia were associated with higher mortality rates than were most other medications used for neuropsychiatric symptoms. The association between mortality and antipsychotics is not well understood and may be due to a direct medication effect or the pathophysiology underlying neuropsychiatric symptoms that prompt antipsychotic use.

Reliability of patient responses in pay for performance schemes: analysis of national General Practitioner Patient Survey data in England

OBJECTIVE To assess the robustness of patient responses to a new national survey of patient experience as a basis for providing financial incentives to doctors. DESIGN Analysis of the representativeness of the respondents to the GP Patient Survey compared with those who were sampled (5.5 million patients registered with 8273 general practices in England in January 2009) and with the general population. Analysis of non-response bias looked at the relation between practice response rates and scores on the survey. Analysis of the reliability of the survey estimated the proportion of the variance of practice scores attributable to true differences between practices. RESULTS The overall response rate was 38.2% (2.2 million responses), which is comparable to that in surveys using similar methodology in the UK. Men, young adults, and people living in deprived areas were under-represented among respondents. However, for questions related to pay for performance, there was no systematic association between response rates and questionnaire scores. Two questions which triggered payments to general practitioners were reliable measures of practice performance, with average practice-level reliability coefficients of 93.2% and 95.0%. Less than 3% and 0.5% of practices had fewer than the number of responses required to achieve conventional reliability levels of 90% and 70%. A change to the payment formula in 2009 resulted in an increase in the average impact of random variation in patient scores on payments to general practitioners compared with payments made in 2007 and 2008. CONCLUSIONS There is little evidence to support the concern of some general practitioners that low response rates and selective non-response bias have led to systematic unfairness in payments attached to questionnaire scores. The study raises issues relating to the validity and reliability of payments based on patient surveys and provides lessons for the UK and for other countries considering the use of patient experience as part of pay for performance schemes.

Systematic reviews from astronomy to zoology: myths and misconceptions.

Systematic literature reviews are widely used as an aid to evidence based decision making. For example, reviews of randomised controlled trials are regularly used to answer questions about the effectiveness of healthcare interventions. The high profile of systematic reviews as a cornerstone of evidence based medicine, however, has led to several misconceptions about their purpose and methods. Among these is the belief that systematic reviews are applicable only to randomised controlled trials and that they are incapable of dealing with other forms of evidence, such as from non-randomised studies or qualitative research. The systematic literature review is a method of locating, appraising, and synthesising evidence. The value of regularly updated systematic reviews in the assessment of effectiveness of healthcare interventions was dramatically illustrated by Antman and colleagues, who showed that review articles failed to mention advances in treatment identified by an updated systematic review.1  It is nearly a quarter of a century since Gene Glass coined the term “meta-analysis” to refer to the quantitative synthesis of the results of primary studies.2 The importance of making explicit efforts to limit bias in the review of literature, however, has been emphasised by social scientists at least since the 1960s.3 In recent years systematic reviews have found an important role in health services research, and the growing interest in evidence based approaches to decision making makes it likely that their use will increase. Not everybody accepts that systematic reviews are necessary or desirable, and as one moves further away from the clinical applications of systematic reviews cynicism about their utility grows. Several arguments are commonly used to reject a wider role for systematic reviews, and these arguments are often based on major misconceptions about the history, purpose, methods, and uses of systematic reviews. I have examined eight common myths about …

ABC of burns. Introduction.

Burns are one of the most devastating conditions encountered in medicine. The injury represents an assault on all aspects of the patient, from the physical to the psychological. It affects all ages, from babies to elderly people, and is a problem in both the developed and developing world. All of us have experienced the severe pain that even a small burn can bring. However the pain and distress caused by a large burn are not limited to the immediate event. The visible physical and the invisible psychological scars are long lasting and often lead to chronic disability. Burn injuries represent a diverse and varied challenge to medical and paramedical staff. Correct management requires a skilled multidisciplinary approach that addresses all the problems facing a burn patient. This series provides an overview of the most important aspects of burn injuries for hospital and non-hospital healthcare workers.workers. Figure 1    Top: Child with 70% full thickness burns, which required resuscitation, intensive care support, and extensive debridement and skin grafting. Left: The same child one year later at a burns camp, having made a good recovery. A reasonable outcome is possible ...

Oncologists' perceptions of the effects of cancer patients' companions on physician-patient interactions

To determine physicians' perceptions of the effects that the companions of cancer patients have on physician-patient communication, semistructured interviews were conducted with 12 oncologists (6 medical, 4 surgical, and 2 radiation) from a total population of 21 oncologists. The physicians estimated that threefourths of their patients brought companions with them to consultations and said that these consultations were more complex for the physician. The behaviors of the companions varied from domination to passive note taking, and the companions who were young professional men or older women who accompanied their husbands were the most assertive and asked the most questions. All possible coalitions were observed during medical visits. The physicians perceived that companions and patients often had different agendas and noted differences in the companions' behaviors according to their gender and whether they lived in rural or urban areas.

Screening for concomitant diseases in peripheral vascular patients. Results of a systematic approach.

BACKGROUND Patients considered for arterial surgery, have been shown to have a high incidence of coexistent cardiac, vascular and other diseases, affecting operative risk and survival. We developed a systematic workup strategy for detecting these coexistent diseases in our vascular surgical patients, mainly based on non-invasive diagnostic techniques. METHODS We evaluated 200 consecutive patients, admitted to the department of vascular surgery in an academic teaching hospital, in order to establish the total incidence of relevant concomitant disorders, the extent to which this screening yielded previously unknown diagnostic information, and the impact on short-term (one year) survival. RESULTS Coronary artery disease was present in 46% of the patients; 22% had active ischaemia, newly diagnosed in 5.5%. Impaired cardiac function was found in 37%: severely impaired in 12%, newly diagnosed in 27%. Carotid artery disease was present in 32%: critical stenoses were found in 9%; new diagnoses in 29.9%. Aortic aneurysms were present in 7%, newly diagnosed in 5%. Severe renal artery stenosis was present in 5%, newly diagnosed in 3.5%. Sixteen % of the patients had chronic obstructive pulmonary disease, newly diagnosed in 3.5%, and 4.5% had unexpected disorders, which were all new diagnoses. Overall, new diagnoses were reached in 64.5% of the population, affecting therapeutic strategy immediately in 21% of the patients. The presence of coronary artery disease and of cardiac failure were clearly related to one year survival. CONCLUSIONS We conclude that a systematic screening strategy, mainly based on noninvasive techniques, can detect the presence of concomitant diseases in the vascular surgical patient. Most important seem the newly diagnosed diseases altering surgical management in one out of every five patients; they also have important implications for patient prognosis.

Political and economic aspects of the transition to universal health coverage.

Countries have reached universal health coverage by different paths and with varying health systems. Nonetheless, the trajectory toward universal health coverage regularly has three common features. The first is a political process driven by a variety of social forces to create public programmes or regulations that expand access to care, improve equity, and pool financial risks. The second is a growth in incomes and a concomitant rise in health spending, which buys more health services for more people. The third is an increase in the share of health spending that is pooled rather than paid out-of-pocket by households. This pooled share is sometimes mobilised as taxes and channelled through governments that provide or subsidise care--in other cases it is mobilised in the form of contributions to mandatory insurance schemes. The predominance of pooled spending is a necessary condition (but not sufficient) for achieving universal health coverage. This paper describes common patterns in countries that have successfully provided universal access to health care and considers how economic growth, demographics, technology, politics, and health spending have intersected to bring about this major development in public health.

Frontal stroke syndromes.

The frontal lobe is the largest lobe of the brain, and it is thus commonly involved in stroke. Moreover, almost one in five strokes is limited to the prerolandic areas. This high frequency of anatomical involvement is in sharp contrast with the apparent rarity of clinical frontal dysfunction in stroke. It is remarkable that frontal behavioral syndromes have been rather uncommonly reported in patients with stroke as compared to patients with other diseases, such as brain tumor. This fact is paradoxical, because an acute process (stroke) is expected to yield more clinical dysfunction than a more chronic disease (tumor). A volume effect may be the main factor leading to this phenomenon. Another interesting aspect of frontal strokes is the contribution of so-called 'silent' strokes, the recurrence of which may nevertheless lead to intellectual decline and compromise recovery from another stroke with more specific neurologic dysfunction. The contribution of stroke to understanding of frontal lobe dysfunction is important, because of the focal nature of this disease, and great opportunity for clinical-topographic classification correlations. One of the first modern attempts to develop a clinical-topographic classification of frontal lobe lesions came from the school of Luria, who tried to delineate three main types of frontal lobe syndromes (premotor syndrome, prefrontal syndrome, medial-frontal syndrome). Recent anatomic correlates using MRI make it possible to improve this classification. We suggest considering six main clinical-anatomic frontal stroke syndromes: (1) prefrontal; (2) premotor; (3) superior medial; (4) orbital-medial; (5) basal forebrain; (6) white matter. Finally, another fascinating topic relates to frontal lobe symptomatology due to stroke sparing the frontal cortex or white matter. This occurs mainly in three instances: lenticulo-capsular stroke, caudate stroke, and thalamic stroke. Studies using blood flow or metabolism measurements suggest that diaschisis (frontal lobe dysfunction from a remote lesion) may play a role. We believe that this is more likely to be related to dynamic interruption of complex circuitry than to static frontal lobe deactivation.

Inappropriate inhaler use: assessment of use and patient preference of seven inhalation devices. EDICI.

Inefficient inhaler technique is a common problem resulting in poor drug delivery, decreased disease control and increased inhaler use. The aim of this study was to assess patients' use of different inhaler devices and to ascertain whether patient preference is indicative of ease of use and whether current inhaler use has any influence on either technique or preference. We also wished to define the most appropriate method of selecting an inhaler for a patient, taking into account observed technique and device cost. One hundred patients received instruction, in randomized order, in the use of seven different inhaler devices. After instruction they were graded (using predetermined criteria) in their inhaler technique. After assessment patients were asked which three inhalers they most preferred and which, if any, they currently used. Technique was best using the breath-actuated inhalers; the Easi-Breathe and Autohaler, with 91% seen to have good technique. The pressurized metered dose inhaler (pMDI) fared poorly, in last position with only 79% of patients showing good technique, despite being the most commonly prescribed. The Easi-Breathe was by far the most popular device with the patients. The Autohaler came in second position closely followed by the Clickhaler and Accuhaler. The majority of patients (55%) currently used the pMDI but the pMDI did not score highly for preference or achieve better grades than the other devices. Only 79% of patients tested could use the pMDI effectively even after expert instruction yet it continues to be commonly prescribed. This has important repercussions for drug delivery and hence disease control. Prescribing a patient's preferred device increases cost but can improve efficiency and therefore be cost effective in the long term. Using an inexpensive device (pMDI) when technique is good and the patient's preferred inhaler device when not is one way to optimize delivery and may even reduce cost.

The association of Red cell distribution width and in-hospital mortality in older adults admitted to the emergency department

BACKGROUND The objective of the study was to test the hypothesis that elevated red cell distribution width (RDW) at admission increases the risk of mortality in older patients admitted to the emergency department (ED). METHODS We performed a retrospective analysis of patients admitted to the ED between May 2013 and October 2013. We included patients who were older than 65 years who visited the ED with any medical problems. Baseline RDW values were measured at the time of admission to the ED. The primary outcome was all-cause in-hospital mortality. Multivariate logistic analysis was performed. RESULTS A total of 1,990 patients were finally included in this study. The mean age was 75 years (SD 7), and 936 (47 %) subjects were male. The in-hospital mortality rate was 3.76 % (74 patients). RDW values higher in non-survivors than in survivors (15.9 ± 2.5 vs. 13.8 ± 1.7, p < 0.001). Multivariate logistic analysis showed that RDW was associated with all-cause in-hospital mortality after adjusting for other confounding factors. DISCUSSION RDW value at admission is an independent predictor of all-cause in-hospital mortality among patients older than 65 years. After adjustment for multiple confounders, the all-cause in-hospital mortality rate increased by 21.8% for each 1% increase in RDW. CONCLUSION These results show that RDW at admission is associated with in-hospital mortality among patients older than 65. Thus, RDW at admission may represent a surrogate marker of disease severity. We caution against using these findings to aid clinical decision-making process until they are externally validated.

Why do patients with multimorbidity in England report worse experiences in primary care? Evidence from the General Practice Patient Survey

OBJECTIVES To describe and explain the primary care experiences of people with multiple long-term conditions in England. DESIGN AND METHODS Using questionnaire data from 906,578 responders to the English 2012 General Practice Patient Survey, we describe the primary care experiences of patients with long-term conditions, including 583,143 patients who reported one or more long-term conditions. We employed mixed effect logistic regressions to analyse data on six items covering three care domains (access, continuity and communication) and a single item on overall primary care experience. We controlled for sociodemographic characteristics, and for general practice using a random effect, and further, controlled for, and explored the importance of, health-related quality of life measured using the EuroQoL (EQ-5D) scale. RESULTS Most patients with long-term conditions report a positive experience of care at their general practice (after adjusting for sociodemographic characteristics and general practice, range 74.0-93.1% reporting positive experience of care across seven questions) with only modest variation by type of condition. For all three domains of patient experience, an increasing number of comorbid conditions is associated with a reducing percentage of patients reporting a positive experience of care. For example, compared with respondents with no long-term condition, the OR for reporting a positive experience is 0.83 (95% CI 0.80 to 0.87) for respondents with four or more long-term conditions. However, this relationship is no longer observed after adjusting for health-related quality of life (OR (95% CI) single condition=1.23 (1.21 to 1.26); four or more conditions=1.31 (1.25 to 1.37)), with pain making the greatest difference among five quality of life variables included in the analysis. CONCLUSIONS Patients with multiple long-term conditions more frequently report worse experiences in primary care. However, patient-centred measures of health-related quality of life, especially pain, are more important than the number of conditions in explaining why patients with multiple long-term conditions report worse experiences of care.

Venous thrombosis in cancer patients: insights from the FRONTLINE survey.

BACKGROUND Venous thromboembolism (VTE) is a common complication in cancer patients and a significant cause of morbidity and mortality. However, little information is available on oncologists' perceptions of the risk of VTE and its management. The Fundamental Research in Oncology and Thrombosis (FRONTLINE) study is the first comprehensive global survey of thrombosis and cancer. The study was designed to collect data on the perceived risk and patterns of practice with regard to VTE in cancer patients undergoing surgical and medical management of their malignancy and to provide information on international and regional practice patterns, allowing for the design of research studies to answer the concerns of practicing clinicians. METHODS Literature reviews were performed to provide a current evidence base against which to compare the findings, and a survey was developed under the guidance of an advisory board. A paper-based reply-paid questionnaire was distributed globally between July and November 2001 to clinicians involved in cancer care and was made available on a dedicated website. FINDINGS A total of 3,891 completed responses were available for analysis. Brain and pancreatic tumors were considered to carry a high risk for VTE, and 80% of respondents considered the use of central venous lines to be associated with a high risk of VTE. Marked differences were seen in the use of thromboprophylaxis for surgical and medical cancer patients, with over 50% of surgeons reporting that they initiated thromboprophylaxis routinely, while most medical oncologists reported using thromboprophylaxis in less than 5% of medical patients. Low molecular weight heparin (LMWH) was the most popular method of thromboprophylaxis employed in both surgical and medical patients and was more favored by European than U.S. clinicians. Some 20% of respondents reported using aspirin for prophylaxis, despite there being no reliable evidence for this agent as effective in prevention in this population. For the treatment of VTE, LMWH was again the most common initial treatment, although, for the long-term, oral anticoagulation therapy was widely adopted. Many patients were treated for VTE on an outpatient basis, and secondary prevention of VTE was typically continued for 3 to 6 months after an episode of deep vein thrombosis or for longer in the case of pulmonary embolism. INTERPRETATION The results of the FRONTLINE survey demonstrate a need for guidelines to direct clinical practice in line with evidence-based data concerning cancer and VTE. Oncologists need to be educated regarding the true risks of VTE associated with certain cancers and on strategies for prevention and treatment to reduce the morbidity and mortality associated with VTE in all cancer patients. The study has also helped identify areas for future research.

Preoperative C-reactive protein predicts mid-term outcome after cardiac surgery.

BACKGROUND C-reactive protein (CRP) is a known risk factor for cardiovascular events in the healthy population and in patients with coronary artery disease. High CRP levels before cardiac surgery are associated with worse short-term outcome, but its role after discharge home remains unknown. The study objective was to evaluate the effect of CRP on short-term and mid-term outcome after cardiac surgery. METHODS From August 2000 to May 2004, values for preoperative CRP were available for 597 unselected patients undergoing cardiac operations. CRP was used to divide this cohort in two groups: a low inflammatory status (LHS) group of 354 patients with CRP of less than 0.5 mg/dL, and a high inflammatory status (HIS) group of 243 patients with a CRP of 0.5 mg/dL or more. Follow-up lasted a maximum of 3 years (median, 1.8 +/- 1.5 years) and was 92.6% complete. RESULTS In-hospital mortality was 8.2% in the HIS group and 3.4% in the LIS group (odds ratio [OR], 2.61; p = 0.02). Incidence of postoperative infections was 16.5% in the HIS group and 5.1% in the LIS group (OR, 3.25; p = 0.0001). Sternal wound infections were also more frequent in the HIS group (10.7% versus 2.8%; OR, 3.43; p = 0.002). During follow-up, the HIS group had worse survival (88.5% +/- 2.9% versus 91.9% +/- 2.5%; OR, 1.93; p = 0.05) and a higher need of hospitalization for cardiac-related causes (73.6% +/- 6% versus 86.5% +/- 3.2%; OR, 1.82; p = 0.05). CONCLUSIONS Patients undergoing cardiac surgery with a CRP level of 0.5 mg/dL or more are exposed to a higher risk of in-hospital mortality and postoperative infections. Despite surgical correction of cardiac disease, a high preoperative CRP value is an independent risk factor for mid-term survival and hospitalization for cardiac causes.

painDETECT: a new screening questionnaire to identify neuropathic components in patients with back pain.

OBJECTIVE Nociceptive and neuropathic components both contribute to pain. Since these components require different pain management strategies, correct pain diagnosis before and during treatment is highly desirable. As low back pain (LBP) patients constitute an important subgroup of chronic pain patients, we addressed the following issues: (i) to establish a simple, validated screening tool to detect neuropathic pain (NeP) components in chronic LBP patients, (ii) to determine the prevalence of neuropathic pain components in LBP in a large-scale survey, and (iii) to determine whether LBP patients with an NeP component suffer from worse, or different, co-morbidities. METHODS In co-operation with the German Research Network on Neuropathic Pain we developed and validated the painDETECT questionnaire (PD-Q) in a prospective, multicentre study and subsequently applied it to approximately 8000 LBP patients. RESULTS The PD-Q is a reliable screening tool with high sensitivity, specificity and positive predictive accuracy; these were 84% in a palm-top computerised version and 85%, 80% and 83%, respectively, in a corresponding pencil-and-paper questionnaire. In an unselected cohort of chronic LBP patients, 37% were found to have predominantly neuropathic pain. Patients with NeP showed higher ratings of pain intensity, with more (and more severe) co-morbidities such as depression, panic/anxiety and sleep disorders. This also affected functionality and use of health-care resources. On the basis of given prevalence of LBP in the general population, we calculated that 14.5% of all female and 11.4% of all male Germans suffer from LBP with a predominant neuropathic pain component. CONCLUSION Simple, patient-based, easy-to-use screening questionnaires can determine the prevalence of neuropathic pain components both in individual LBP patients and in heterogeneous cohorts of such patients. Since NeP correlates with more intense pain, more severe co-morbidity and poorer quality of life, accurate diagnosis is a milestone in choosing appropriate therapy.

The structure of informal care: are there differences by race?

This study investigated whether there are race differences in the structure of informal caregiving networks. Data on 3,793 functionally impaired persons age 65 and over from the 1989 National Long-Term Care Survey were analyzed. The size of the total caregiver network and the unpaid network did not differ by race, but the likelihood of there being a non-immediate family member among unpaid caregivers was higher among disabled older blacks. These findings raise questions about whether race differences in nursing home utilization and paid long-term care services, documented in other studies, can be explained by differences in caregiving arrangements.

Mental health in prison populations. A review--with special emphasis on a study of Danish prisoners on remand.

OBJECTIVE To review the literature on mental health and psychiatric morbidity in prison populations and relate findings to a Danish study on remand prisoners. METHOD The literature is reviewed and subdivided in the following section: validity of psychometrics in prison populations, prevalence of psychiatric disorders prior to imprisonment, incidence of psychiatric disorders during imprisonment, psychopathy related to psychiatric comorbidity, dependence syndromes with special emphasis on different administrations of heroin use (smoke vs. injection). The results are compared with a longitudinal Danish study on remand prisoners in either solitary confinement (SC) or non-SC. RESULTS Many factors must be taken into consideration when dealing with prisoners and mental health, e.g. international differences, the prison setting, demographics and methodological issues. The prison populations in general are increasing worldwide. Psychometrics may perform differently in prison populations compared with general populations with the General Health Questionnaire-28 having a low validity in remand prisoners. Psychiatric morbidity including schizophrenia is higher and perhaps increasing in prison populations compared with general populations with dependence syndromes being the most frequent disorders. The early phase of imprisonment is a vulnerable period with a moderately high incidence of adjustment disorders and twice the incidence in SC compared with non-SC. Prevalence of psychopathy is lower in European than North American prisons. Medium to high scores of psychopathy is related to higher psychiatric comorbidity. Opioid dependence is the most frequent drug disorder with subjects using injection representing a more dysfunctional group than subjects using smoke administration. Many mentally ill prisoners remain undetected and undertreated. CONCLUSION There is a growing population of mentally ill prisoners being insufficiently detected and treated.

Physician knowledge levels and barriers to coronary risk prevention in women: survey results from the Women and Heart Disease Physician Education Initiative.

BACKGROUND Few studies have examined whether physician knowledge, attitudes, or practice patterns might contribute to gender disparities in the primary prevention of coronary heart disease (CHD), including among physicians caring for the largest number of reproductive-age women, obstetricians and gynecologists (OB/GYNs). We sought to identify barriers affecting the provision of recommended coronary risk factor therapies in women. METHODS We surveyed internists and OB/GYNs who attended Grand Rounds presentations developed for the New York State Women and Heart Disease Physician Education Initiative. This program was designed to improve screening and management of coronary risk factors in women. Attendees were asked to complete a 7-minute questionnaire. RESULTS The mean age of the 529 respondents was 40.3 years (standard deviation = 12.3), 75.1% were internists (n=378), and 42.7% (n=226) were women. Physicians correctly responded to 71.5% of the 13 questions assessing knowledge of coronary risk prevention (range, 4-13). Almost one third of internists and half of the OB/GYNs did not know that tobacco use was the leading cause of myocardial infarction in young women. For patients who smoked tobacco, only two thirds of internists and 55.4% of OB/GYNs reported suggesting a quit date (p=.007). After controlling for covariates, physicians who did not perceive time as a barrier were more likely to discuss smoking cessation (odds ratio=1.7 [1.1-2.7]). CONCLUSIONS Among the internists and OB/GYNs surveyed, time was perceived as a barrier to implementing risk prevention. These physicians also underestimated the impact of tobacco use as a risk factor for CHD in young women. To lessen gender disparities in CHD prevention, both specialties need time-efficient educational programs that reflect specialty differences.

The Antiretroviral Therapy in Lower Income Countries (ART-LINC) Collaboration and ART Cohort Collaboration (ART-CC) groups Summary

BACKGROUND Highly active antiretroviral therapy (HAART) is being scaled up in developing countries. We compared baseline characteristics and outcomes during the first year of HAART between HIV-1-infected patients in low-income and high-income settings. METHODS 18 HAART programmes in Africa, Asia, and South America (low-income settings) and 12 HIV cohort studies from Europe and North America (high-income settings) provided data for 4810 and 22,217, respectively, treatment-naïve adult patients starting HAART. All patients from high-income settings and 2725 (57%) patients from low-income settings were actively followed-up and included in survival analyses. FINDINGS Compared with high-income countries, patients starting HAART in low-income settings had lower CD4 cell counts (median 108 cells per muL vs 234 cells per muL), were more likely to be female (51%vs 25%), and more likely to start treatment with a non-nucleoside reverse transcriptase inhibitor (NNRTI) (70%vs 23%). At 6 months, the median number of CD4 cells gained (106 cells per muL vs 103 cells per muL) and the percentage of patients reaching HIV-1 RNA levels lower than 500 copies/mL (76%vs 77%) were similar. Mortality was higher in low-income settings (124 deaths during 2236 person-years of follow-up) than in high-income settings (414 deaths during 20,532 person-years). The adjusted hazard ratio (HR) of mortality comparing low-income with high-income settings fell from 4.3 (95% CI 1.6-11.8) during the first month to 1.5 (0.7-3.0) during months 7-12. The provision of treatment free of charge in low-income settings was associated with lower mortality (adjusted HR 0.23; 95% CI 0.08-0.61). INTERPRETATION Patients starting HAART in resource-poor settings have increased mortality rates in the first months on therapy, compared with those in developed countries. Timely diagnosis and assessment of treatment eligibility, coupled with free provision of HAART, might reduce this excess mortality.

Awake craniotomy with brain mapping as the routine surgical approach to treating patients with supratentorial intraaxial tumors: a prospective trial of 200 cases.

OBJECT Awake craniotomy was performed as the standard surgical approach to supratentorial intraaxial tumors, regardless of the involvement of eloquent cortex, in a prospective trial of 200 patients surgically treated by the same surgeon at a single institution. METHODS Patient presentations, comorbid conditions, tumor locations, and the histological characteristics of lesions were recorded. Brain mapping was possible in 195 (97.5%) of 200 patients. The total number of patients sustaining complications was 33 for an overall complication rate of 16.5%. There were two deaths in this series, for a mortality rate of 1%. New postoperative neurological deficits were seen in 13% of the patients, but these were permanent in only 4.5% of them. Complication rates were higher in patients who had gliomas or preoperative neurological deficits and in those who had undergone prior radiation therapy or surgery. No patient who entered the operating room neurologically intact sustained a permanent neurological deficit postoperatively. Of the most recent 50 patients treated, three (6%) required a stay in the intensive care unit, and the median total hospital stay was 1 day. CONCLUSIONS Use of awake craniotomy can result in a considerable reduction in resource utilization without compromising patient care by minimizing intensive care time and total hospital stay. Awake craniotomy is a practical and effective standard surgical approach to supratentorial tumors with a low complication rate, and provides an excellent alternative to craniotomy performed with the patient in the state of general anesthesia because it allows the opportunity for brain mapping and avoids general anesthesia.

Extravasation injuries on regional neonatal units.

This survey of regional neonatal intensive care units determined a prevalence of 38 per 1000 neonates who sustained an extravasation injury that caused skin necrosis. Most injuries occurred in infants of 26 weeks gestation or less, with parenteral nutrition infused through intravenous cannulae. Common treatments were exposing wounds to the air, infiltration with hyaluronidase and saline, and occlusive dressings.

Laparoscopic adhesiolysis in patients with chronic abdominal pain: a blinded randomised controlled multi-centre trial.

BACKGROUND Laparoscopic adhesiolysis for chronic abdominal pain is controversial and is not evidence based. We aimed to test our hypothesis that laparoscopic adhesiolysis leads to substantial pain relief and improvement in quality of life in patients with adhesions and chronic abdominal pain. METHODS Patients had diagnostic laparoscopy for chronic abdominal pain attributed to adhesions; other causes for their pain had been excluded. If adhesions were confirmed during diagnostic laparoscopy, patients were randomly assigned either to laparoscopic adhesiolysis or no treatment. Treatment allocation was concealed from patients, and assessors were unaware of patients' treatment and outcome. Pain was assessed for 1 year by visual analogue score (VAS) score (scale 0-100), pain change score, use of analgesics, and quality of life score. Analysis was by intention to treat. FINDINGS Of 116 patients enrolled for diagnostic laparoscopy, 100 were randomly allocated either laparoscopic adhesiolysis (52) or no treatment (48). Both groups reported substantial pain relief and a significantly improved quality of life, but there was no difference between the groups (mean change from baseline of VAS score at 12 months: difference 3 points, p=0.53; 95% CI -7 to 13). INTERPRETATION Although laparoscopic adhesiolysis relieves chronic abdominal pain, it is not more beneficial than diagnostic laparoscopy alone. Therefore, laparoscopic adhesiolysis cannot be recommended as a treatment for adhesions in patients with chronic abdominal pain.

A systematic review of randomized controlled trials of acupuncture in the treatment of depression.

BACKGROUND Acupuncture has become a popular complementary and alternative treatment approach. This review examined the randomized controlled trials (RCTs) examining the effects of acupuncture treatment of depression. METHODS RCTs of the treatment of depression with acupuncture were located using MEDLINE, Allied and Complementary Medicine and the Cochrane Central Register of Controlled Trials. The methodology of RCTs was assessed using the Jadad criteria, and elements of research design, i.e., randomization, blinding, assessment of attrition rates, were quantified for systematic comparisons among studies. RESULTS Among the 9 RCTs examined, five were deemed to be of low quality based upon Jadad criteria. The odds ratios derived from comparing acupuncture with control conditions within the RCTs suggests some evidence for the utility of acupuncture in depression. General trends suggest that acupuncture modalities were as effective as antidepressants employed for treatment of depression in the limited studies available for comparison. However, placebo acupuncture treatment was often no different from intended verum acupuncture. LIMITATIONS The RCTs extracted were limited by small sample sizes, imprecise enrollment criteria, problems with randomization, blinding, brief duration of study and lack of longitudinal follow-up. CONCLUSIONS Despite the findings that the odds ratios of existing literature suggest a role for acupuncture in the treatment of depression, the evidence thus far is inconclusive. However, efforts are being made to standardize complementary approaches to treat depression, and further systematized research into their use is warranted.

Adapting the WHO package of essential noncommunicable disease interventions, Samoa

Problem Samoa has been struggling to address the burden of noncommunicable diseases at the health system, community and individual levels. Approach The World Health Organization (WHO) package of essential noncommunicable disease interventions for primary health care in low-resource settings was adopted in seven villages throughout Samoa in 2015. The National Steering Committee Members designed and implemented a screening process, and local facilitators and health-care workers collected health and lifestyle data. The WHO/International Society of Hypertension risk assessment was used on villagers older than 40 years to identify people at high risk of noncommunicable disease. Local setting Samoa is a small island developing state with increasing morbidity and mortality due to noncommunicable diseases. A national representative survey indicated that 50.1% (595/1188) of the Samoan adult population is at high risk of such diseases. High numbers of noncommunicable diseases are undiagnosed or untreated, because of shortage of health-care staff and lack of awareness of risk factors. Relevant changes The teams collected data from 2234 adults. For people older than 40 years, 6.7% (54/804) were identified as being at high-risk and were encouraged to seek treatment or manage risk factors. Community members developed an awareness programme to improve understanding of lifestyle risk factors. Lessons learnt Engaging community members was crucial in conducting a successful screening campaign. By identifying those villagers at high risk of developing noncommunicable diseases, early intervention was possible. Education improved awareness of the symptom-free nature of early-stage noncommunicable diseases.

Antipsychotic prescribing patterns in Germany: a retrospective analysis using a large outpatient prescription database.

Data of prescribing practices for antipsychotics are of great interest with respect to quality of care. Consequently, we analysed all prescriptions under the statutory health insurance redeemed at pharmacies in Southern Germany between July 1999 and December 2001. The database covers prescriptions for approximately 25 million people. Up to 6% of the population were prescribed an antipsychotic at least once during the study period. Most prescriptions were for conventional antipsychotics and written by non-specialists. Patients receiving second generation antipsychotics were more likely to receive continuous antipsychotic therapy. For a large proportion of patients, antipsychotic polypharmacy, as well as comedication for somatic illnesses, were observed. In particular, drugs for the treatment of cardiovascular and metabolic disorders were frequently co-prescribed. Physicians should consider patients' cardiovascular and metabolic risk profile when making treatment choices. The data suggest that the majority of antipsychotics are used for the treatment of disorders other than schizophrenia. It is important to raise awareness among non-specialists about the indications, efficacy and side-effects of the antipsychotics because these physicians account for the majority of antipsychotic prescriptions.

Risk factors at medical school for subsequent professional misconduct: multicentre retrospective case-control study

OBJECTIVE To determine whether there are risk factors in a doctor's time at medical school that are associated with subsequent professional misconduct. DESIGN Matched case-control study. Setting Records from medical schools and the General Medical Council (GMC). PARTICIPANTS 59 doctors who had graduated from any one of eight medical schools in the United Kingdom in 1958-97 and had a proved finding of serious professional misconduct in GMC proceedings in 1999-2004 (cases); 236 controls (four for each case) were selected by systematic sampling from matching graduation cohorts. Case-control status was revealed by the GMC after completion of data entry. MAIN OUTCOME MEASURE Odds ratios for being a "case," with multivariable conditional logistic regression of potential risk factors including pre-admission characteristics and progress during the course. These data were obtained from anonymised copies of the students' progress files held by their original medical schools. RESULTS Univariate conditional logistic regression analysis found that cases were more likely to be men, to be of lower estimated social class, and to have had academic difficulties during their medical course, especially in the early years. Multivariable analysis showed that male sex (odds ratio 9.80, 95% confidence interval 2.43 to 39.44, P=0.001), lower social class (4.28, 1.52 to 12.09, P=0.006), and failure of early or preclinical examinations (5.47, 2.17 to 13.79, P<0.001) were independently associated with being a case. CONCLUSIONS This small study suggests that male sex, a lower socioeconomic background, and early academic difficulties at medical school could be risk factors for subsequent professional misconduct. The findings are preliminary and should be interpreted with caution. Most doctors with risk factors will not come before the GMC's disciplinary panels.

Cardiovascular risk and events in 17 low-, middle-, and high-income countries.

BACKGROUND More than 80% of deaths from cardiovascular disease are estimated to occur in low-income and middle-income countries, but the reasons are unknown. METHODS We enrolled 156,424 persons from 628 urban and rural communities in 17 countries (3 high-income, 10 middle-income, and 4 low-income countries) and assessed their cardiovascular risk using the INTERHEART Risk Score, a validated score for quantifying risk-factor burden without the use of laboratory testing (with higher scores indicating greater risk-factor burden). Participants were followed for incident cardiovascular disease and death for a mean of 4.1 years. RESULTS The mean INTERHEART Risk Score was highest in high-income countries, intermediate in middle-income countries, and lowest in low-income countries (P<0.001). However, the rates of major cardiovascular events (death from cardiovascular causes, myocardial infarction, stroke, or heart failure) were lower in high-income countries than in middle- and low-income countries (3.99 events per 1000 person-years vs. 5.38 and 6.43 events per 1000 person-years, respectively; P<0.001). Case fatality rates were also lowest in high-income countries (6.5%, 15.9%, and 17.3% in high-, middle-, and low-income countries, respectively; P=0.01). Urban communities had a higher risk-factor burden than rural communities but lower rates of cardiovascular events (4.83 vs. 6.25 events per 1000 person-years, P<0.001) and case fatality rates (13.52% vs. 17.25%, P<0.001). The use of preventive medications and revascularization procedures was significantly more common in high-income countries than in middle- or low-income countries (P<0.001). CONCLUSIONS Although the risk-factor burden was lowest in low-income countries, the rates of major cardiovascular disease and death were substantially higher in low-income countries than in high-income countries. The high burden of risk factors in high-income countries may have been mitigated by better control of risk factors and more frequent use of proven pharmacologic therapies and revascularization.

Primary care and health insurance among women released from New York City jails.

Factors associated with primary care utilization and health insurance coverage were examined among 511 women leaving jail in New York City from 1997-2001. One year after release, roughly half of the sample reported primary care utilization (47%) and health insurance coverage (56%). Neither outcome was more likely among those reporting diabetes, asthma, or depression. Primary care utilization was more likely among those reporting receipt of public benefits, health insurance coverage, moderate social support, avoidance of illegal activity, and HIV seropositivity. Health insurance coverage was associated with receipt of public benefits, hospitalization, primary care, and avoiding re-arrest. This study demonstrated that a majority of women leaving jail, including those with chronic diseases, lack primary care. These data highlight the need to plan for continuity of care from corrections to the community and suggest further that this can be facilitated with provision of health benefits and social support.

Swaddling: a systematic review.

Swaddling was an almost universal child-care practice before the 18th century. It is still tradition in certain parts of the Middle East and is gaining popularity in the United Kingdom, the United States, and The Netherlands to curb excessive crying. We have systematically reviewed all articles on swaddling to evaluate its possible benefits and disadvantages. In general, swaddled infants arouse less and sleep longer. Preterm infants have shown improved neuromuscular development, less physiologic distress, better motor organization, and more self-regulatory ability when they are swaddled. When compared with massage, excessively crying infants cried less when swaddled, and swaddling can soothe pain in infants. It is supportive in cases of neonatal abstinence syndrome and infants with neonatal cerebral lesions. It can be helpful in regulating temperature but can also cause hyperthermia when misapplied. Another possible adverse effect is an increased risk of the development of hip dysplasia, which is related to swaddling with the legs in extension and adduction. Although swaddling promotes the favorable supine position, the combination of swaddling with prone position increases the risk of sudden infant death syndrome, which makes it necessary to warn parents to stop swaddling if infants attempt to turn. There is some evidence that there is a higher risk of respiratory infections related to the tightness of swaddling. Furthermore, swaddling does not influence rickets onset or bone properties. Swaddling immediately after birth can cause delayed postnatal weight gain under certain conditions, but does not seem to influence breastfeeding parameters.

Preterm patent ductus arteriosus: A continuing conundrum for the neonatologist?

How to manage the preterm patent ductus arteriosus (PDA) remains a conundrum. On the one hand, physiology and statistical association with adverse outcomes suggest that it is pathological. On the other hand, clinical trials of treatment strategies have failed to show any long-term benefit. Ultrasound studies of PDA have suggested that the haemodynamic impact may be much earlier after birth than previously thought (in the first hours); however, we still do not know when to treat PDA. Studies that have tested symptomatic or pre-symptomatic treatment are mainly historical and have not tested the effect of no treatment. Prophylactic treatment is the best-studied regimen but improvements in some short-term outcomes do not translate to any difference in longer-term outcomes. Neonatologists have been reluctant to engage in trials that test treatment against almost never treating. Observations of very early postnatal haemodynamic significance suggest that targeting treatment on the basis of the early postnatal constrictive response of the duct may optimize benefits. A pilot trial of this strategy showed reduction in the incidence of pulmonary haemorrhage but more trials of this strategy are needed.

Lung cancer treatment waiting times and tumour growth.

We report a single-centre prospective audit of 29 lung cancer patients who were awaiting radical (potentially curative) radiotherapy. This was the total number assessed as suitable for radical treatment by one consultant during 1999. At the time of assessment they had been newly diagnosed and staged with a computed tomographic (CT) scan of chest. They had a subsequent CT scan prior to starting treatment for the purpose of planning the radiation fields. We have now measured tumour size on the diagnostic scans and compared this with the size on the planning scans. We have documented the delay between diagnostic and planning CT scanning and the total time between first hospital visit and starting treatment. Two patients had progression of symptoms while on the waiting list, making them unfit for radical treatment, and another four had tumour progression on planning CT such that the tumour volume was too large for radical treatment. Therefore, 21% of potentially curable patients became incurable on the waiting list. The delay between diagnostic and planning CT scans ranged from 18 to 131 days (median 54), with increases in the cross-sectional tumour size over that period ranging zero to 373%. The delay between the first hospital visit and starting treatment was 35-187 days (median 94); between the date of the radiotherapy request and the starting date for treatment it was 23-61 days (median 44). Limited access to specialists is the reason most often advanced for the poor performance of the UK in treating lung cancer. This study demonstrates that, even for the select minority of patients who have specialist referral and are deemed suitable for potentially curative treatment, the outcome is prejudiced by waiting times that allow tumour progression.
