The Effect of Telemedicine Interventions on Patients with Diabetic Foot Ulcers: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Objective

The meta-analysis was performed to evaluate the effectiveness of telemedicine interventions on patients with diabetic foot ulcers (DFU). Approach: The authors conducted a comprehensive search across eight databases. The aim was to identify randomized controlled trials examining the effectiveness of telemedicine for patients with DFU. Methodological qualities of included studies were assessed using Cochrane Handbook for Systematic Reviews of Intervention. Subsequently, a meta-analysis was conducted using RevMan 5.3 to synthesize the findings.

Results

Ten studies involving 1,678 patients with DFU were included in the meta-analysis. In comparison to the face-to-face intervention group, telemedicine interventions significantly reduced the amputation rate (risk ratio = 0.64, 95% confidence interval [CI] = 0.44-0.92, p = 0.02), decreased costs (mean difference [MD] = -4158.51, 95% CI = -7304.69 to -1012.34, p = 0.01), better controlled fasting blood glucose (MD = -0.89, 95% CI = -1.43 to -0.36, p = 0.001), and achieved superior glycated hemoglobin control (MD = -0.71, 95% CI = -1.01 to -0.41, p < 0.00001). No significant differences were observed between the telemedicine group and the face-to-face group in terms of healing rate, mortality, and healing time. Innovations: Our study suggests that telemedicine is a viable strategy for managing DFU.

Conclusions

The meta-analysis indicates that telemedicine interventions have a positive effect on DFU. Nevertheless, more well-designed and high-quality studies are needed to reach a conclusion with greater confidence.
