Telehealth for diabetes self-management in primary healthcare: A systematic review and meta-analysis

Background: Diabetes mellitus is prevalent worldwide and the majority of the patients with this metabolic disease are managed in primary healthcare settings. Self-management is, therefore, crucial for the health and wellbeing of people with diabetes. Due to the advancement of information technologies, telehealth intervention as self-management measures potentially offer a possible solution in the primary healthcare arena to cope with the increasing demand for diabetes control. Methods: This study aims to systematically review the effectiveness of telehealth on diabetes control self-management in primary healthcare settings. A keyword search was conducted in six databases for randomised controlled trials. Data extraction and quality assessment of the reviewed studies were done with standardised forms and checklists. A meta-analysis was also performed in this review. Results: Of the seven studies included in this review, all of them reported a decreasing level of glycated haemoglobin. Four studies examined the effect of telehealth interventions on fasting plasma glucose levels; however, the overall effects were insignificant. It is, nonetheless, encouraging to see two studies which investigated their effect on two-hour post-meal glucose levels, and showed positive effects for glycaemic control self-management in the short term. This finding, though only from two studies, points to a promising future of utilising telehealth interventions in controlling this metabolic disease in the primary healthcare arena. Conclusions: This review showed positive effects of telehealth interventions for diabetes control self-management at the primary healthcare stage. Further studies are required to evaluate the cost-effectiveness of telehealth interventions. Copyright © 2017 The Author(s).
