Obesity is increasing throughout the industrialised world. If left unchecked it will have major implications for both population health and costs to health services. Health professionals have a key role to play in tackling the obesity problem, but little is known about how they may be encouraged to work more effectively with overweight and obese people.
The main objective was to determine whether health professionals' management or the organisation of care for overweight and obese people could be improved.
We searched the specialised registers of the Cochrane Effective Practice and Organisation of Care Group (May 1997), the Cochrane Depression, Anxiety and Neurosis Group (August 1997), the Cochrane Diabetes Group (August 1997), the Cochrane Controlled Trials Register (September 1997), MEDLINE to January 1998, EMBASE to December 1997, Cinahl (1982 to November 1997), PsycLit (1974 to December 1997), Sigle (1980 to November 1997), 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.
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.
Two reviewers independently extracted data and assessed study quality.
Twelve studies were included involving more than 393 providers and 3392 patients. Four studies were identified for comparison 1. Three were professional-oriented interventions (the use of reminders and training) and the fourth was a study of professional and organisational interventions of shared care. No studies were identified for comparisons 2 or 3. Eight 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 generally poor quality.
REVIEWER'S CONCLUSIONS: At present, decisions about improving provision of services must be based on the evidence of patient interventions and good clinical judgement. Further research is needed to identify cost effective strategies for improving the management of obesity.
肥胖问题在整个工业化世界呈上升趋势。若不加以控制,将对民众健康和医疗服务成本产生重大影响。医疗专业人员在解决肥胖问题中起着关键作用,但对于如何鼓励他们更有效地与超重和肥胖人群合作,我们知之甚少。
主要目的是确定能否改善医疗专业人员对超重和肥胖人群的管理或护理组织。
我们检索了Cochrane有效实践与护理组织小组的专业登记册(1997年5月)、Cochrane抑郁、焦虑与神经症小组(1997年8月)、Cochrane糖尿病小组(1997年8月)、Cochrane对照试验登记册(1997年9月)、截至1998年1月的MEDLINE、截至1997年12月的EMBASE、CINAHL(1982年至1997年11月)、PsycLit(1974年至1997年12月)、Sigle(1980年至1997年11月)、Sociofile(1974年至1997年10月)、论文摘要(1861年至1998年1月)、会议论文索引(1973年至1998年1月)、继续医学教育资源数据库。我们还手工检索了七种主要期刊并联系了该领域的专家。
关于医疗服务提供者对肥胖的管理或护理组织的随机试验、前后对照研究以及中断时间序列分析,以改善医疗服务提供者的实践或患者结局。我们进行了三项预先设定的比较和一项事后比较。1. 旨在改善医疗专业人员对超重/肥胖患者的管理或医疗服务提供的干预措施比常规护理更有效。2. 旨在纠正对超重/肥胖患者的负面态度及相关行为的干预措施比常规护理更有效。3. 旨在改变超重/肥胖人群服务结构的组织干预措施比针对医疗专业人员的教育或行为干预措施更有效。4. 不同组织干预措施间的比较。
两名评价员独立提取数据并评估研究质量。
纳入了12项研究,涉及393名以上医疗服务提供者和3392名患者。为比较1确定了4项研究。其中3项是针对专业人员的干预措施(使用提醒和培训),第4项是关于共享护理的专业和组织干预措施的研究。未找到用于比较2或3的研究。为事后比较4确定了8项研究。这些研究比较了减肥干预措施的实施者或干预措施的实施环境。纳入的研究具有异质性,质量普遍较差。
目前,关于改善服务提供的决策必须基于患者干预的证据和良好的临床判断。需要进一步研究以确定改善肥胖管理的具有成本效益的策略。
