The body of evidence regarding self-management programs (SMPs) for adult chronic non-cancer pain (CNCP) is steadily growing, and regular updates are needed for effective decision-making.

To systematically identify, critically appraise, and summarize the findings from randomized controlled trials (RCTs) of SMPs for CNCP.

We searched relevant databases from 2009 to August 2021 and included English-language RCT publications of SMPs compared with usual care for CNCP among adults (18+ years old). The primary outcome was health-related quality of life (HR-QoL). We conducted meta-analysis using an inverse variance, random-effects model and calculated the standardized mean difference (SMD) and associated 95% confidence interval (CI) and statistical heterogeneity using the I 2 statistic.

From 8538 citations, we included 28 RCTs with varying patient populations, standards for SMPs, and usual care. No RCTs were classified as having a low risk of bias. There was no evidence of a significant improvement in overall HR-QoL, irrespective of pain type, immediately post-intervention (SMD 0.01, 95%CI −0.21 to 0.24; I 2 57%; 11 RCTs; 979 participants), 1–4 months post-intervention (SMD 0.02, 95%CI −0.16 to 0.20; I 2 48.7%; 12 RCTs; 1160 participants), and 6–12 months post-intervention (SMD 0.07, 95%CI −0.06 to 0.21; I 2 26.1%; 9 RCTs; 1404 participants). Similar findings were made for physical and mental HR-QoL, and for specific QoL assessment scales (e.g., SF-36).

There is a lack of evidence that SMPs are efficacious for CNCP compared with usual care. Standardization of SMPs for CNCP and better planned/conducted RCTs are needed to confirm these conclusions.
