Assessing the impact of telehealth on blood glucose management among patients with diabetes: a systematic review and meta-analysis of randomized controlled trials.

Introduction: The increasing prevalence of diabetes mellites (DM), especially type 2 diabetes mellitus, presents significant challenges for healthcare systems. Effective blood glucose management is essential for preventing serious complications, and telehealth offers a promising approach to improve patient engagement and adherence. The effectiveness of telehealth on blood glucose management should be investigated. The evaluated metric for diabetes management plans in this study was the change in blood glucose levels, specifically HbA1c, as an indicator of glycemic control. The impact of telehealth interventions on these outcomes was analyzed across various patient groups. This review conducts a comprehensive analysis of the current literature to offer insights that can guide clinical practices and inform policymakers about the advantages of telehealth in managing diabetes.

Methods: In this study, several evidence-based databases and relevant clinical trial registries were searched to evaluate the effects of telehealth on blood glucose management among patients with diabetes. The included studies were randomized controlled trials that compared telehealth with traditional in-person management. Microsoft Excel was used to extract and sort the data before it was exported to STATA/MP 17.0 for analysis. A weighted inverse variance random-effects model with a 95% confidence interval was employed to pool the data. Egger's test and Cochrane I² statistics were used to assess publication bias and heterogeneity, respectively.

Result: This review identified six randomized controlled trials (RCTs) involving a total of 3,995 patients, with 2,022 in the telehealth intervention group and 1,973 in the control group, conducted across the USA, Asia, and Europe. The analysis showed a significant improvement in blood glucose control for patients using telehealth, evidenced by a Standard Mean Difference (SMD) of 0.20 (95% CI: 0.10-0.29; p < 0.001), with USA studies reflecting the highest SMD of 0.24 and diabetic veterans showing an even greater SMD of 0.41.

Conclusion and recommendations: This study demonstrates that telehealth interventions significantly enhance blood glucose management among patients with diabetes. The findings highlight the need for healthcare systems to prioritize telehealth integration into diabetes management protocols while developing tailored interventions to meet the diverse needs of various patient populations.
