Self-management education programmes led by lay leaders (rather than health professionals such as doctors or nurses) are becoming common as a way of trying to promote self care for people with chronic conditions. We assessed systematically the effects of these programmes. We included results from seventeen studies which involved a total of 7442 people with chronic conditions including arthritis, diabetes, hypertension and chronic pain. While many of the programmes were similar, they differed in which condition they were for, which measurements researchers reported, and how effective the programmes were.
We found that these programmes may lead to modest, short-term improvements in patients' confidence to manage their condition and perceptions of their own health. They also increased how often people took aerobic exercise. Whilst there were small improvements in pain, disability, fatigue and depression, the improvements were not clinically important. The programmes did not improve quality of life, alter the number of times patients visited their doctor or reduce the amount of time spent in hospital. No adverse events were reported in any of the studies.
Lay-led self-management education programmes may lead to small, short-term improvements in participants' self-efficacy, self-rated health, cognitive symptom management, and frequency of aerobic exercise. There is currently no evidence to suggest that such programmes improve psychological health, symptoms or health-related quality of life, or that they significantly alter healthcare use. Future research on such interventions should explore longer term outcomes, their effect on clinical measures of disease and their potential role in children and adolescents.
Lay-led self-management programmes are becoming widespread in the attempt to promote self-care for people with chronic conditions.
To assess systematically the effectiveness of lay-led self-management programmes for people with chronic conditions.
We searched: the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library 2005, Issue 1), MEDLINE (January 1986 to May 2006), EMBASE (January 1986 to June 2006), AMED (January 1986 to June 2006), CINAHL (January 1986 to June 2006), DARE (1994 to July 2006, National Research Register (2000 to July 2006), NHS Economic Evaluations Database (1994 to July 2006), PsycINFO (January 1986 to June 2006), Science Citation Index (January 1986 to July 2006), reference lists and forward citation tracking of included studies. We contacted principal investigators and experts in the field. There were no language restrictions.
Randomised controlled trials (RCTs) comparing structured lay-led self-management education programmes for chronic conditions against no intervention or clinician-led programmes.
Two authors independently assessed trial quality and extracted data. We contacted study authors for additional information. Results of RCTs were pooled using a random-effects model with standardised mean differences (SMDs) or weighted mean differences (WMDs) for continuous outcomes.
We included seventeen trials involving 7442 participants. The interventions shared similar structures and components but studies showed heterogeneity in conditions studied, outcomes collected and effects. There were no studies of children and adolescents, only one study provided data on outcomes beyond six months, and only two studies reported clinical outcomes.
Primary outcomes
Health status: There was a small, statistically-significant reduction in: pain (11 studies, SMD -0.10 (95% confidence interval (CI) -0.17 to -0.04)); disability (8 studies, SMD -0.15 (95% CI -0.25 to -0.05); and fatigue (7 studies, SMD -0.16 (95% CI -0.23 to -0.09); and small, statistically-significant improvement in depression (6 studies, SMD -0.16 95% CI -0.24 to -0.07). There was a small (but not statistically- or clinically-significant) improvement in psychological well-being (5 studies; SMD -0.12 (95% CI -0.33 to 0.09)); but no difference between groups for health-related quality of life (3 studies; WMD -0.03 (95% CI -0.09 to 0.02). Six studies showed a statistically-significant improvement in self-rated general health (WMD -0.20 (95% CI -0.31 to -0.10).
Health behaviours: 7 studies showed a small, statistically-significant increase in self-reported aerobic exercise (SMD -0.20 (95% CI -0.27 to -0.12)) and a moderate increase in cognitive symptom management (4 studies, WMD -0.55 ( 95% CI -0.85 to -0.26)).
Healthcare use: There were no statistically-significant differences between groups in physician or general practitioner attendance (9 studies; SMD -0.03 (95% CI -0.09 to 0.04)). There were also no statistically-significant differences between groups for days/nights spent in hospital (6 studies; WMD -0.32 (95% CI -0.71 to 0.07)).
Self-efficacy: (confidence to manage condition) showed a small statistically-significant improvement (10 studies): SMD -0.30, 95% CI -0.41 to -0.19.
No adverse events were reported in any of the studies.
