Digital Primary Care, Chronic Disease Management, and Health System Resilience: A Comparative Public Health Analysis of Telemedicine Integration in Canada and South Korea

Abstract

Digital health has become a major institutional and clinical strategy for improving healthcare access, chronic disease management, and health system resilience. This study examines how telemedicine integration influences primary care accessibility, patient engagement, treatment continuity, and chronic disease outcomes through a comparative public health analysis of Canada and South Korea. The article argues that telemedicine effectiveness depends not merely on technology availability but on healthcare governance, reimbursement policy, digital infrastructure, clinical workflow integration, data interoperability, patient trust, and equity-sensitive implementation. Using comparative health systems analysis, epidemiological interpretation, digital health policy review, and evidence-based synthesis, the study evaluates two advanced but institutionally distinct health systems. Canada represents a publicly financed, provincially administered system with strong primary care orientation but persistent geographic access barriers, while South Korea represents a technologically advanced, insurance-based system with high digital infrastructure capacity and historically cautious telemedicine regulation. The findings indicate that digital primary care can improve continuity for chronic disease management when integrated with clinical governance, remote monitoring, patient education, and equitable access strategies. However, digital interventions may widen disparities when older adults, rural communities, low-income groups, and digitally excluded patients face barriers to use. This article contributes to medical and health sciences scholarship by integrating epidemiology, health systems governance, behavioral medicine, digital health implementation, and chronic disease management into a comparative framework.
