Effects of patient activation intervention on chronic diseases: A meta-analysis

Abstract

Background Patient activation has been described as a potential strategy to improve chronic disease self-management. However, the effects of patient activation interventions on psychological and behavioral outcomes have not been systematically evaluated. Purpose This study was designed to evaluate the effects of patient activation interventions on physiological, psychological, behavioral, and health-related quality of life outcomes in patients with chronic diseases. Methods We systematically searched four databases (PubMed, Cochrane, CINAHL, and Embase) from inception to September 1, 2017. We identified English- and Chinese-language published reports of randomized controlled trials that evaluated the effects of patient activation interventions for adults with chronic diseases. Study selection, data extraction, and quality assessment were performed by two reviewers independently. We summarized the intervention effects with Hedges's g values and 95% confidence intervals using a random-effects model. We used the Cochrane Handbook to assess the methodological quality of the randomized controlled trials. Results Twenty-six randomized controlled trials were included in the qualitative synthesis and meta-analysis. In terms of overall study quality, most of the included studies were affected by performance and detection bias. Patient activation interventions produced significant effects on outcomes related to physiological, psychological, behavioral, and health-related quality of life in the context of chronic diseases. The following effect sizes were obtained: (a) physiological, namely, glycated hemoglobin = -0.31 (p
