RESUMO
Telemedicine is the delivery of healthcare services using information and communication technologies to diagnose, treat, and prevent diseases. The COVID-19 pandemic has accelerated the adoption of telemedicine, transforming how healthcare is delivered, especially in remote and underserved areas. Despite its potential, no systematic reviews have been conducted in the last five years to assess the effectiveness of telemedicine for managing diabetes in rural populations. This review addresses this gap by evaluating studies on telemedicine's impact on glycemic control among diabetic patients in these settings. We searched five databases: PubMed, Google Scholar, ClinicalTrials.gov, ScienceDirect, and Science.gov, covering studies published in the last five years. Of the 331 articles identified, 10 met our inclusion criteria: English-language studies from the past five years involving adults in rural areas or comparing rural and urban settings, focusing on telemedicine's impact on glycemic control in diabetic patients. In many studies, the findings revealed that telemedicine interventions integrated into structured programs significantly improved HbA1c levels. Successful implementation requires local infrastructure and consistent patient-provider interactions, although increased healthcare provider workloads may affect sustainability. Telemedicine alone was less effective for patients with complex comorbidities, suggesting that a combined approach with in-person visits may be more effective. This review highlights telemedicine's potential to replace routine in-person visits for diabetes management in rural areas, demonstrating significant improvements in HbA1c levels, medication adherence, and timely care management support. Future research should focus on randomized controlled trials in rural settings, hybrid care models that optimize in-person visit frequency and remote monitoring, and addressing technological challenges such as broadband access and platform usability to ensure sustainable telehealth interventions.
