Evaluating Telemedicine for Chronic Disease Management in Low- and Middle-Income Countries During Corona Virus Disease 2019 (COVID-19)

Background: The rapid expansion of telemedicine globally, especially during the COVID-19 pandemic, has been critical for maintaining the continuity of chronic care, including in low- and middle-income countries (LMICs). In the context of maintaining health services during major hazards, telemedicine offers a potential solution for reducing the impact of associated disruptions and maintaining the functionality of hospitals. This study aims to evaluate the application of telemedicine for chronic diseases in LMICs during COVID-19, with a focus on its role in enhancing health system resilience during disastrous events. Methods: A systematised review was conducted by searching PubMed, Scopus, Global Health, and Google Scholar for primary literature published between January 2020 and July 2023. English-language articles on chronic disease management were targeted; they were freely accessible and excluded abstracts, conference papers, posters, and grey literature. A multilevel evaluation framework was applied, covering access, cost, patient and health worker experiences, and the effectiveness of telemedicine interventions. Results: After screening one thousand six hundred seventy-eight records, twenty-three studies and two additional snowball-sourced papers from ten countries were included. Findings revealed that while telemedicine enhanced access to care, patient experiences, and effectiveness, cost analysis remains an understudied area. Discrepancies in perspectives were noted between patients and health workers, particularly regarding access and effectiveness. Nevertheless, the majority of studies agree on telemedicine’s positive impact on the accessibility and resilience of health systems during major emergencies, which reduces costs and improves the overall patient experience. However, concerns such as outdated regulations and policies and poor internet connectivity pose a challenge that needs to be addressed. Conclusions: This review highlights the potential of telemedicine in strengthening health system resilience, particularly in LMICs where more work is needed to update regulations and policies and to strengthen infrastructure for more affordable and uninterruptable connectivity. Further research is needed to explore the long-term sustainability of telemedicine in these contexts and to identify strategies for successful implementation across diverse public health challenges.
