Improving health professionals' management and the organisation of care for overweight and obese people

Abstract

Background Obesity is increasing throughout the industrialised world. If left unchecked it will have major implications for both population health and costs to health services. Objectives To assess whether health professionals' management or the organisation of care for overweight and obese people could be improved. Search strategy We searched the specialised registers of the Cochrane Effective Practice and Organisation of Care Group (April 2000), the Cochrane Depression, Anxiety and Neurosis Group (August 1997), the Cochrane Diabetes Group (August 1997), the Cochrane Controlled Trials Register (September 1997), MEDLINE to April 2000, EMBASE to February 2000, Cinahl (1982 to February 2000), PsycLit (1974 to May 2000), Sigle (1980 to April 2000), Sociofile (1974 to October 1997), Dissertation Abstracts (1861 to January 1998), Conference Papers Index (1973 to January 1998), Resource Database in Continuing Medical Education. We also hand searched seven key journals and contacted experts in the field. Selection criteria Randomised trials, controlled before-and-after studies and interrupted time series analyses of providers' management of obesity or the organisation of care to improve provider practice or patient outcomes. We addressed three a priori comparisons and a fourth post hoc comparison. 1. Interventions aimed at improving health professionals' management or the delivery of health care for overweight/obese patients are more effective than usual care. 2. Interventions aimed at redressing negative attitudes and related practices towards overweight/obese patients are more effective than usual care. 3. Organisational interventions designed to change the structure of services for overweight/obese people are more effective than educational or behavioural interventions for health professionals. 4. Comparisons of different organisational interventions. Data collection and analysis Two reviewers independently extracted data and assessed study quality. Main results Eighteen studies were included involving 446 providers and 4158 patients. Six studies were identified for comparison 1. Five were professional-oriented interventions (the use of reminders and training) and the sixth was a study of professional and organisational interventions of shared care. No studies were identified for comparisons 2 or 3. Twelve studies were identified for post hoc comparison 4. These compared either the deliverer of weight loss interventions or the setting of interventions. The included studies were heterogeneous and of questionable quality according to the Cochrane Effective Practice and Organisation of Care (EPOC) Group criteria. Authors' conclusions At present, there are few solid leads about improving obesity management, although reminder systems, brief training interventions, shared care, in-patient care and dietitian-led treatments may all be worth further investigation. In addition, decisions for the improvement of provision of services must be based on the existing evidence on interventions with patients and good clinical judgement. Further research is needed to identify cost effective strategies for improving the management of obesity.
