    Input: Background Dementia care in the Netherl and s is shifting from fragmented , ad hoc care to more coordinated and personalised care . Case management contributes to this shift . The linkage model and a combination of intensive case management and joint agency care models were selected based on their emerging prominence in the Netherl and s. It is unclear if these different forms of case management are more effective than usual care in improving or preserving the functioning and well-being at the patient and caregiver level and at the societal cost . The objective of this article is to describe the design of a study comparing these two case management care models against usual care .  Clinical and cost outcomes are investigated while care processes and the facilitators and barriers for implementation of these models are considered . Design Mixed methods include a prospect i ve , observational , controlled , cohort study among persons with dementia and their primary informal caregiver in regions of the Netherl and s with and without case management including a qualitative process evaluation . Inclusion criteria for the cohort study are : community-dwelling individuals with a dementia diagnosis who are not terminally-ill or anticipate admission to a nursing home within 6 months and with an informal caregiver who speaks fluent Dutch . Person with dementia-informal caregiver dyads are followed for two years . The primary outcome measure is the Neuropsychiatric Inventory for the people with dementia and the General Health Question naire for their caregivers . Secondary outcomes include : quality of life and needs assessment in both persons with dementia and caregivers , activity of daily living , competence of care , and number of crises . Costs are measured from a societal perspective using cost diaries . Process indicators measure the quality of care from the participant ’s perspective . The qualitative study uses purposive sampling methods to ensure a wide variation of respondents . Semi-structured interviews with stakeholders based on the theoretical model of adaptive implementation are planned . Discussion This study provides relevant insights into care processes , description of two case management models along with clinical and economic data from persons with dementia and caregivers to clarify important differences in two case management care models compared to usual care OBJECTIVE Direct physician order entry ( POE ) offers many potential benefits , but evidence suggests that POE requires substantially more time than traditional paper-based ordering methods . The Medical Gopher is a well-accepted system for direct POE that has been in use for more than 15 years . The authors hypothesized that physicians using the Gopher would not spend any more time writing orders than physicians using paper-based methods . DESIGN A r and omized controlled trial of POE using the Medical Gopher system in 11 primary care internal medicine practice s. MEASUREMENTS The authors collected detailed time use data using time motion studies of the physicians and surveyed their opinions about the POE system . RESULTS The authors found that physicians using the Gopher spent 2.2 min more per patient overall , but when duplicative and administrative tasks were taken into account , physicians were found to have spent only 0.43 min more per patient . With experience , the order entry time fell by 3.73 min per patient . The survey revealed that the physicians believed that the system improved their patient care and wanted the Gopher to continue to be available in their practice s. CONCLUSIONS Little extra time , if any , was required for physicians to use the POE system . With experience in its use , physicians may even save time while enjoying the many benefits of POE AIM This paper reports a study to examine the effectiveness of a 6-month dementia care programme for Chinese families living with and caring for a relative with dementia , compared with routine family support services in Hong Kong . BACKGROUND Recognizing the adverse psychosocial health effects inherent in dementia care , different psychosocial interventions provided preliminary evidence of their effectiveness in improving family members ' knowledge and skills in caregiving and delaying dementia sufferers ' illness deterioration and institutionalization . Little is known about the effects of such interventions for family caregivers ' psychosocial health conditions , particularly in non-Western population s. METHODS A r and omized controlled trial was conducted with 92 Chinese families of a relative with dementia in two dementia care centres in Hong Kong . They were r and omly selected from a dementia client list and then r and omly assigned to receive either the dementia family care programme ( n=46 ) , or routine care only ( n=46 ) . Clients ' symptoms and institutionalization , and caregivers ' quality of life , burden and social support at recruitment , 1 week , and 12 and 18 months following intervention were measured and compared between the study groups using repeated measures MANOVAS followed by Helmert 's contrast tests . Data was collected over a period of 24 months , between September 2007 and August 2009 . RESULTS Results of the MANOVAS and contrast tests indicated that at 18-month follow-up , participants in the family programme reported significantly greater improvements in clients ' symptoms and institutionalization rates , and caregivers ' quality of life and burden , when compared with their counterparts in the routine care group . CONCLUSION These findings provide evidence that the dementia care family programme can improve the psychosocial functioning of both clients with dementia and their family caregivers in a Chinese population . Further research is recommended to investigate whether this intervention can also apply to families with different socio-economic background s and across cultures CONTEXT Most older adults with dementia will be cared for by primary care physicians , but the primary care practice environment presents important challenges to providing quality care . OBJECTIVE To test the effectiveness of a collaborative care model to improve the quality of care for patients with Alzheimer disease . DESIGN , SETTING , AND PATIENTS Controlled clinical trial of 153 older adults with Alzheimer disease and their caregivers who were r and omized by physician to receive collaborative care management ( n = 84 ) or augmented usual care ( n = 69 ) at primary care practice s within 2 US university-affiliated health care systems from January 2002 through August 2004 . Eligible patients ( identified via screening or medical record ) met diagnostic criteria for Alzheimer disease and had a self-identified caregiver . INTERVENTION Intervention patients received 1 year of care management by an interdisciplinary team led by an advanced practice nurse working with the patient 's family caregiver and integrated within primary care . The team used st and ard protocol s to initiate treatment and identify , monitor , and treat behavioral and psychological symptoms of dementia , stressing nonpharmacological management . MAIN OUTCOME MEASURES Neuropsychiatric Inventory ( NPI ) administered at baseline and at 6 , 12 , and 18 months . Secondary outcomes included the Cornell Scale for Depression in Dementia ( CSDD ) , cognition , activities of daily living , re source use , and caregiver 's depression severity . RESULTS Initiated by caregivers ' reports , 89 % of intervention patients triggered at least 1 protocol for behavioral and psychological symptoms of dementia with a mean of 4 per patient from a total of 8 possible protocol s. Intervention patients were more likely to receive  cholinesterase inhibitors  ( 79.8 % vs 55.1 % ; P = .002 ) and  antidepressants  ( 45.2 % vs 27.5 % ; P = .03 ) . Intervention patients had significantly fewer behavioral and psychological symptoms of dementia as measured by the total NPI score at 12 months ( mean difference , -5.6 ; P = .01 ) and at 18 months ( mean difference , -5.4 ; P = .01 ) . Intervention caregivers also reported significant improvements in distress as measured by the caregiver NPI at 12 months ; at 18 months , caregivers showed improvement in depression as measured by the Patient Health Question naire-9 . No group differences were found on the CSDD , cognition , activities of daily living , or on rates of hospitalization , nursing home placement , or death . CONCLUSIONS Collaborative care for the treatment of Alzheimer disease result ed in significant improvement in the quality of care and in behavioral and psychological symptoms of dementia among primary care patients and their caregivers . These improvements were achieved without significantly increasing the use of antipsychotics or sedative-hypnotics . TRIAL REGISTRATION clinical trials.gov Identifier : NCT00246896 BACKGROUND It is believed that timely recognition and diagnosis of dementia is a pre-condition for improving care for both older adults with dementia and their informal caregivers . However , diagnosing dementia often occurs late in the disease . This means that a significant number of patients with early symptoms of dementia and their informal caregivers may lack appropriate care . OBJECTIVES To compare the effects of case management and usual care among community-dwelling older adults with early symptoms of dementia and their primary informal caregivers . DESIGN R and omized controlled trial with measurements at baseline and after 6 and 12 months . SETTING Primary care in West-Friesl and , the Netherl and s. PARTICIPANTS 99 pairs of community-dwelling older adults with dementia symptoms ( defined as abnormal screening for symptoms of dementia ) and their primary informal caregivers . INTERVENTION 12 months of case management by district nurses for both older adults and informal caregivers versus usual care . MEASUREMENTS PRIMARY OUTCOME informal caregiver 's sense of competence . SECONDARY OUTCOMES caregiver 's quality of life , depressive symptoms , and burden , and patient 's quality of life . Process measurements : intervention fidelity and caregiver 's satisfaction with the quality of case management . RESULTS Linear mixed model analyses showed no statistically significant and clinical ly relevant differences over time between the two groups . The process evaluation revealed that intervention fidelity could have been better . Meanwhile , informal caregivers were satisfied with the quality of case management . CONCLUSION This study shows no benefits of case management for older adults with dementia symptoms and their primary informal caregivers . One possible explanation is that case management , which has been recommended among diagnosed dementia patients , may not be beneficial if offered too early . However , on the other h and , it is possible that : ( 1 ) case management will be effective in this group if more fully implemented and adapted or aim ed at informal caregivers who experience more severe distress and problems ; ( 2 ) case management is beneficial but that it is not seen in the timeframe studied ; ( 3 ) case management might have undetected small benefits . This has to be established . Trial registration ISCRTN83135728 STUDY QUESTION Did the  Medicare Alzheimer 's Disease Demonstration , with its goal of improving caregiver outcomes through case management and subsidized community services , affect the nursing home entry rate of treatments with dementia compared to controls ? DATA SOURCES Interviews conducted at baseline and six months thereafter . Measures include date of nursing home entry , client and caregiver health , and income . STUDY DESIGN The demonstration r and omly assigned voluntary applicants into treatment and control groups . Treatment group cases were eligible for case management and for an 80 percent discount on community care benefits , up to about $ 600 per month . DATA COLLECTION All cases received baseline and semi-annual assessment interviews for up to three years after enrollment . Analyses are among cases that remained in the demonstration for more than 30 days after enrollment ( n = 8,095 ) . PRINCIPAL FINDINGS The intervention of case management and subsidized community service had no effect on nursing home entry rates for treatments overall , compared to those of controls , and few effects on treatment subgroups , with the exception of one site where it may have increased nursing home entry rates . CONCLUSIONS Providing case management and subsidized community services with the goal of improving caregiver outcomes may have little effect on nursing home entry rates for people with dementia Objective : To determine the effectiveness of a counseling and support intervention for spouse caregivers in delaying time to nursing home placement of patients with Alzheimer disease ( AD ) , and identify the mechanisms through which the intervention accomplished this goal . Methods : We conducted a r and omized controlled trial of an enhanced counseling and support intervention compared to usual care . Participants were a referred volunteer sample of 406 spouse caregivers of community-dwelling patients who had enrolled in the study over a 9.5-year period . The intervention consisted of six sessions of individual and family counseling , support group participation , and continuous availability of ad hoc telephone counseling . Structured question naires were administered at baseline and at regular follow-up intervals , every 4 months for the first year and every 6 months thereafter . Cox proportional hazard models were used to test the effects of the intervention on the time to nursing home placement for the patients after controlling for multiple time-invariant and time-dependent predictors of placement . Results : Patients whose spouses received the intervention experienced a 28.3 % reduction in the rate of nursing home placement compared with usual care controls ( hazard ratio = 0.717 after covariate adjustment , p = 0.025 ) . The difference in model-predicted median time to placement was 557 days . Improvements in caregivers ’ satisfaction with social support , response to patient behavior problems , and symptoms of depression collectively accounted for 61.2 % of the intervention ’s beneficial impact on placement . Conclusion : Greater access to effective programs of counseling and support could yield considerable benefits for caregivers , patients with Alzheimer disease , and society Objectives To develop and evaluate the effectiveness of a home based intervention in reducing caregiver burden , promoting caregiver mental health and reducing behavioural problems in elderly persons with dementia . Methodology and Principal Findings This was a r and omised controlled trial in which the person with dementia-caregiver dyad was r and omly allocated either to receive the intervention immediately or to a waiting list group which received the intervention after 6 months . It was carried out in communities based in two talukas ( administrative blocks ) in Goa , India . Mild to moderate cases with dementia ( diagnosed using the DSM IV criteria and grade d using the Clinical
