    Input: The efficacy of a communication skills training programme was shown through a r and omised trial . Oncologists ( N=160 ) from 34 cancer centres were allocated to written feedback plus course ; course alone ; written feedback alone or control .  Each clinician had 6 – 10 interviews  with patients videotaped at baseline and 3 months postintervention . Analysis of videotapes revealed improvements in the communication skills of clinicians r and omised to training ( n=80 ) compared with others ( n=80 ) . A 12-month follow-up assessment is reported here . Robust Poisson conditional analyses of counts of changes in communication behaviours revealed no demonstrable attrition in those who had shown improvement previously , including fewer leading questions , appropriate use of focused and open-ended questions and responses to patient cues . Additional skills , not apparent at 3 months , were now evident ; the estimated effect sizes corresponded to 81 % fewer interruptions ( P=0.001 ) and increased summarising of information to 38 % ( P=0.038 ) . However , expressions of empathy ( 54 % , P=0.001 ) declined . The overall results show that 12 – 15 months postintervention , clinicians had integrated key communication skills into clinical practice and were applying others . This is the first RCT to show an enduring effect of communication skills training with transfer into the clinic This study compared an activation intervention to passive education in a r and omized attention-control trial of 232 patients with type 2 diabetes . The activation intervention was based on Exp and ing Patient Involvement in Care ( EPIC ) trials , and was compared to time-matched passive education viewing of ADA video-tapes . Patient demographics and clinical characteristics of their diabetes were assessed with question naires , active involvement was assessed via ratings of taped interactions between patients and providers , and serum sample s were analyzed for HbA1c . Patients in the activation condition were rated as more actively involved in discussion s of diabetes self-management , and rated active involvement was predictive of improvement in glycemic control . No effect of the activation intervention was found on HbA1c . Thus , the activation intervention increased the active involvement of patients with type 2 diabetes in visits with practitioners , and active involvement led to improved glycemic control . However , the activation intervention did not improve glycemic control directly The authors assessed whether patient empowerment in the management of hypertension improved more with the practice of shared decision making ( SDM ) than by education programs . In a prospect i ve controlled clinical study , 15 general practitioners in Nuremberg , Germany who were specially trained to conduct SDM consultations participated in a 12-month study . Hypertensive patients ( N=86 ) were included ; N=40 were in the SDM group and N=46 were in the control group , if blood pressures were > or = 135 / 85 mm Hg ( self measurement ) and patients had no signs of cardiovascular complications or severe hypertension . All participants in the SDM group and the control group were enrolled in an education program on hypertension in small groups . The SDM group participants also had 4 special consultations to share medical decisions . The main outcome measures were the effect of SDM on blood pressure control . After 1 year blood pressure had decreased in all participants : Delta-9.26 + /- 10.2 mm Hg/Delta-5.33 + /- 9.5 mm Hg in the SDM group ( P<0.001 ) compared to Delta-6.0 + /- 11.8 mm Hg/Delta-3.0 + /- 8.3 mm Hg in the control group . There was no significant difference between the 2 groups . The study group practice d more  SDM  than controls , but blood pressure control was not significantly better . Patient empowerment by means of an education program in small groups and creating awareness of hypertensive disease helps to improve the outcome of hypertension treatment .  SDM , however , did not improve management when compared to an education program , which is much easier to implement in general practice OBJECTIVE Despite the importance of self-management support ( SMS ) , few studies have compared SMS interventions , involved diverse population s , or entailed implementation in safety net setting s. We examined the effects of two SMS strategies across outcomes corresponding to the Chronic Care Model . RESEARCH DESIGN AND METHODS A total of 339 out patients with poorly controlled diabetes from county-run clinics were enrolled in a three-arm trial . Participants , more than half of whom spoke limited English , were uninsured , and /or had less than a high school education , were r and omly assigned to  usual care , interactive weekly automated telephone self-management support with nurse follow-up ( ATSM ) , or monthly group medical visits with physician and health educator facilitation ( GMV ) . We measured 1-year changes in structure ( Patient Assessment of Chronic Illness Care [ PACIC ] ) , communication processes ( Interpersonal Processes of Care [ IPC ] ) , and outcomes ( behavioral , functional , and metabolic ) . RESULTS Compared with the usual care group , the ATSM and GMV groups showed improvements in PACIC , with effect sizes of 0.48 and 0.50 , respectively ( P < 0.01 ) . Only the ATSM group showed improvements in IPC ( effect sizes 0.40 vs. usual care and 0.25 vs. GMV , P < 0.05 ) . Both SMS arms showed improvements in self-management behavior versus the usual care arm ( P < 0.05 ) , with gains being greater for the ATSM group than for the GMV group ( effect size 0.27 , P = 0.02 ) . The ATSM group had fewer bed days per month than the usual care group ( −1.7 days , P = 0.05 ) and the GMV group ( −2.3 days , P < 0.01 ) and less interference with daily activities than the usual care group ( odds ratio 0.37 , P = 0.02 ) . We observed no differences in A1C change . CONCLUSIONS Patient-centered SMS improves certain aspects of diabetes care and positively influences self-management behavior . ATSM seems to be a more effective communication vehicle than GMV in improving behavior and quality of life OBJECTIVE To determine if a patient-centered , computer-assisted diabetes care intervention increased perceived autonomy support , perceived competence ( from self-determination theory ) , and if these constructs mediated the effect of the intervention on ADA/NCQA recommended diabetes care outcomes . DESIGN A r and omized controlled trial of 866 adult type 2 diabetes patients in heterogeneous primary care setting s in Colorado . MAIN OUTCOME MEASURES Perceived autonomy support , perceived competence , patient satisfaction , glycemic control ( HbA1c ) , ratio of total to HDL cholesterol , diabetes distress , and depressive symptoms . RESULTS The computer-assisted intervention increased patient perception of autonomy support relative to a computer-based control condition ( p = .05 ) . Change in perceived competence partially mediated the effects of increased autonomy support on the change in lipids , diabetes distress , and depressive symptoms . The construct of autonomy support was found to be separate from that of patient satisfaction . CONCLUSIONS A patient-centered , computer-assisted intervention was effective in improving diabetes self-management outcomes , in part , because it increased patients ' perception that their autonomy was supported which changed perceived competence . These findings support the self-determination model for health behavior change and the chronic care model and support the further study of the use of these technologies to motivate patients to improve their health outcomes OBJECTIVE To ascertain whether the quality of physician-patient communication makes a significant difference to patient health outcomes . DATA SOURCES The MEDLINE data base was search ed for articles published from 1983 to 1993 using " physician-patient relations " as the primary medical subject heading . Several bibliographies and conference proceedings were also review ed . STUDY SELECTION R and omized controlled trials ( RCTs ) and analytic studies of physician-patient communication in which patient health was an outcome variable . DATA EXTRACTION The following information was recorded about each study : sample size , patient characteristics , clinical setting , elements of communication assessed , patient outcomes measured , and direction and significance of any association found between aspects of communication and patient outcomes . DATA SYNTHESIS Of the 21 studies that met the final criteria for review , 16 reported positive results , 4 reported negative ( i.e. , nonsignificant ) results , and 1 was inconclusive . The quality of communication both in the history-taking segment of the visit and during discussion of the management plan was found to influence patient health outcomes . The outcomes affected were , in descending order of frequency , emotional health , symptom resolution , function , physiologic measures ( i.e. , blood pressure and blood sugar level ) and pain control . CONCLUSIONS Most of the studies review ed demonstrated a correlation between effective physician-patient communication and improved patient health outcomes . The components of effective communication identified by these studies can be used as the basis both for curriculum development in medical education and for patient education programs . Future research should focus on evaluating such educational programs OBJECTIVE The purpose of this study is to determine whether patient activation  is a changing or changeable characteristic and to assess whether changes in activation also are accompanied by changes in health behavior . STUDY METHODS To obtain variability in activation and self-management behavior , a controlled trial with chronic disease patients r and omized into either intervention or control conditions was employed . In addition , changes in activation that occurred in the total sample were also examined for the study period . Using Mplus growth models , activation latent growth classes were identified and used in the analysis to predict changes in health behaviors and health outcomes . DATA SOURCES Survey data from the 479 participants were collected at baseline , 6 weeks , and 6 months . PRINCIPAL FINDINGS Positive change in activation is related to positive change in a variety of self-management behaviors . This is true even when the behavior in question is not being performed at baseline . When the behavior is already being performed at baseline , an increase in activation is related to maintaining a relatively high level of the behavior over time . The impact of the intervention , however , was less clear , as the increase in activation in the intervention group was matched by nearly equal increases in the control group . CONCLUSIONS Results suggest that if activation is increased , a variety of improved behaviors will follow . The question still remains , however , as to what interventions will improve activation OBJECTIVE A case study at the department for heart surgery of an Austrian University Hospital in 2001 , examined the outcome of improved communication aim ed at empowering patients to be more effective co-producers of recuperation after surgery . METHODS Evaluated were the effects of a training program for developing communication skills of health professionals ( physicians , physiotherapists , and nurses ) along with a reorganization of patient information schemes . The clinical outcomes after four types of surgery ( bypass , stent , artificial valve insertion and combination of these ) were observed in 100 patients without ( control group ) and 99 with the intervention administered ( intervention group ) . Two objective and two subjective health outcome parameters were selected for analysis : care level adjusted length of stay in hospital , frequency of post-surgery complications , subjective health , subjective satisfaction with care received . Self-administered breathing exercises  were measured as an intermediary outcome parameter . RESULTS In the intervention group length of hospital stay was shorter ( by 1 day ) , incidence of post-surgery tachyarrhythmia was reduced ( by 15 % ) , transfer to less intensive care levels was faster and patient ratings for communicative quality of care by doctors and nurses were improved . CONCLUSION Professional communication aim ed at empowering patients to act as co producers can indeed have an effect on clinical outcome . PRACTICE IMPLICATION S Staff training and reorganization of communication schemes can be an effective intervention in hospital care Background : Preventive guidelines on cardiovascular risk management recommend lifestyle changes . Support for lifestyle changes may be a useful task for practice nurses , but the effect of such interventions in primary prevention is not clear . We examined the effect of involving patients in nurse-led cardiovascular risk management on lifestyle adherence and cardiovascular risk . Methods : We performed a cluster r and omized controlled trial in 25 practice s that included 615 patients . The intervention consisted of nurse-led cardiovascular risk management , including risk assessment , risk communication , a decision aid and adapted motivational interviewing . The control group received a minimal nurse-led intervention . The self-reported outcome measures at one year were smoking , alcohol use , diet and physical activity . Nurses assessed 10-year cardiovascular mortality risk after one year . Results : There were no significant differences between the intervention groups . The effect of the intervention on the consumption of vegetables and physical activity was small , and some differences were only significant for subgroups . The effects of the intervention on the intake of fat , fruit and alcohol and smoking were not significant . We found no effect between the groups for cardiovascular 10-year risk . Interpretation : Nurse-led risk communication , use of a decision aid and adapted motivational interviewing did not lead to relevant differences between the groups in terms of lifestyle changes or cardiovascular risk , despite significant within-group differences OBJECTIVE To assess the effect of additional training of  practice nurses and general practitioners  in patient centred care on the lifestyle and psychological and physiological status of patients with newly diagnosed type 2 diabetes . DESIGN Pragmatic parallel group design , with r and omisation between practice teams to routine care ( comparison group ) or routine care plus additional training ( intervention group ) ; analysis at one year , allowing for practice effects and stratifiers ; self reporting by patients on communication with practitioners , satisfaction with treatment , style of care , and lifestyle . SETTING 41 practice s ( 21 in intervention group , 20 in comparison group ) in a health region in southern Engl and . SUBJECTS 250/360 patients ( aged 30 - 70 years ) diagnosed with type 2 diabetes and completing follow up at one year ( 142 in intervention group , 108 in comparison 
    Output:
    
Few interventions targeting patient-practitioner communication have assessed the impact on cardiovascular-related clinical outcomes , limiting the ability to determine effectiveness .
