NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Effectiveness of Smartphone-Based Self-Management Interventions on Self-care and Health Relevant Outcomes in Patients with Type 2 Diabetes: A Systematic Review and Meta-analysis
Background:
Type 2 Diabetes Mellitus (T2DM) is a major health problem worldwide. Proper self-management can improve health outcomes and reduces risk of diabetic complications. Recently, smartphone-based technology has been used for self-management programs but their effectiveness in improving self-efficacy, self-care activities, health-related quality of life (HRQoL) and clinical outcomes for patients with T2DM is not well understood.
Objective:
To review the evidence and determine the effectiveness of smartphone-based self-management interventions on self-efficacy, self-care activities, HRQoL, glycated haemoglobin (HbA1c), body mass index (BMI), blood pressure (BP) levels of adults with T2DM.
Methods:
A systematic search of five databases (PubMed, Embase, Cochrane, CINAHL and Scopus) was conducted. Study published in English, from January 2007 to January 2018, were considered. Only randomised controlled trials (RCTs) of smartphone-based self-management interventions for patients with T2DM 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.
Results:
A total of 26 articles, consisting of 22 studies with 2645 participants were included in the review. A meta-analysis conducted on self-efficacy revealed a large improvement of 0.98 (95% confidence interval [CI] 0.42 to 1.55; P < 0.001) with smartphone-based self-management interventions. The effect size on self-care activities was also large (d = 0.90; 95% CI 0.24 to 1.57; P < 0.001). Significant heterogeneity was present among studies pooled for both outcomes and subgroup analyses were conducted for self-efficacy. Smartphone-based self-management interventions also gave a small improvement on HRQoL (d = 0.26; 95% CI 0.06 to 0.47; P = .01) and a significant reduction in HbA1c (pooled MD = -0.55; 95% CI -0.60 to -0.40; P < 0.001). The effects on BMI and BP were not statistically significant.
Conclusions:
Smartphone-based self-management interventions appear to have beneficial effects on self-efficacy, self-care activities and health-relevant outcomes for patients with T2DM. However, more research with good study designs is needed to evaluate the effectiveness of smartphone-based self-care interventions for T2DM.
