Self-Management Education Programmes for Osteoarthritis

Self-management programs may not relieve symptoms in patients with osteoarthritis compared with attention control or usual care. Level of evidence: "C"

The level of evidence is downgraded by study quality and inconsistency

Summary

A Cochrane review [Abstract] 1 included 29 studies with a total of 6753 subjects. The studies compared self-management education programmes to attention control (five studies), usual care (17 studies), information alone (four studies) or another intervention (seven studies). Most interventions included elements of skill and technique acquisition (94%), health-directed activity (85%) and self-monitoring and insight (79%); social integration and support were addressed in only 12%.

Compared with attention control, self-management programmes may not result in significant benefits at 12 months. Low-quality evidence from one study (344 people) indicated that self-management skills were similar in active and control groups: 5.8 points on a 10-point self-efficacy scale in the control group, and the mean difference (MD) between groups was 0.4 points (95% CI -0.39 to 1.19). Low-quality evidence from four studies (575 people) indicated that self-management programmes may lead to a small but clinically unimportant reduction in pain: the SMD between groups was -0.26 (95% CI -0.44 to -0.09); pain was 6 points on a 0 to 10 visual analogue scale (VAS) in the control group, treatment resulted in a mean reduction of 0.8 points (95% CI -0.14 to -0.3) on a 10-point scale, with number needed to treat for an additional beneficial outcome (NNTB) of 8 (95% CI 5 to 23). Low-quality evidence from one study (251 people) indicated that the mean global osteoarthritis score was 4.2 on a 0 to 10-point symptom scale (lower better) in the control group, and treatment reduced symptoms by a mean of 0.14 points (95% CI -0.54 to 0.26). This result does not exclude the possibility of a clinically important benefit in some people (0.5 point reduction included in 95% CI). Low-quality evidence from three studies (574 people) showed no signficant difference in function between groups (SMD -0.19, 95% CI -0.5 to 0.11); mean function was 1.29 points on a 0 to 3-point scale in the control group, and treatment resulted in a mean improvement of 0.04 points with self-management (95% CI -0.10 to 0.02). Low-quality evidence from one study (165 people) showed no between-group difference in quality of life (MD -0.01, 95% CI -0.03 to 0.01) from a control group mean of 0.57 units on 0 to 1 well-being scale. Moderate-quality evidence from five studies (937 people) shows similar withdrawal rates between self-management (13%) and control groups (12%): RR 1.11 (95% CI 0.78 to 1.57). Positive and active engagement in life was not measured.

Compared with usual care, moderate-quality evidence from 11 studies (up to 1 706 participants) indicated that self-management programmes probably provide small benefits up to 21 months, in terms of self-management skills, pain, osteoarthritis symptoms and function, although these are of doubtful clinical importance, and no improvement in positive and active engagement in life or quality of life. Withdrawal rates were similar. Low to moderate quality evidence indicated no important differences in self-management, pain, symptoms, function, quality of life or withdrawal rates between self-management programmes and information alone or other interventions (exercise, physiotherapy, social support or acupuncture).
