Effectiveness of smartphone-based self-management interventions on self-efficacy, self-care activities, health-related quality of life and clinical outcomes in patients with type 2 diabetes: A systematic review and meta-analysis

To review the evidence and determine the effectiveness of smartphone-based self-management interventions on self-efficacy, self-care activities, health-related quality of life, glycated hemoglobin, body mass index (BMI), and blood pressure (BP) levels of adults with type 2 diabetes mellitus . A systematic search of five databases (PubMed, Embase, Cochrane, CINAHL and Scopus) was conducted. Studies published in English from January 2007 to January 2018 were considered. Only randomized controlled trials (RCTs) of smartphone-based self-management interventions for patients with type 2 diabetes mellitus that reported any of the study outcomes were included. Two reviewers independently screened the studies, extracted data and assessed the quality of the studies. Meta-analyses were conducted for the different study outcomes. A total of 26 articles, consisting of 22 studies with 2645 participants, were included in the review. The results from meta-analysis on the studies revealed that as compared to control group, participants received smartphone-based self-management intervention had better self-efficacy with large effect size of 0.98 (P < 0.001), self-care activities with effect size of 0.90 (P < 0.001), health related quality of life with effect size of 0.26 (p=0.01), and lower glycated hemoglobin (pooled MD=-0.55; p<0.001). Subgroup analyses were also conducted for self-efficacy as significant heterogeneity was present among the studies. The effects on BMI and BP were not statistically significant. Smartphone-based self-management interventions appear to have beneficial effects on self-efficacy, self-care activities and health-relevant outcomes for patients with type 2 diabetes mellitus. However, more research with good study design is needed to evaluate the effectiveness of smartphone-based self-care interventions for T2DM.
