This study presents a systematic review of the transformative impact of telemedicine on modern healthcare, with a focus on its potential to enhance patient outcomes, reduce costs, and improve access to care. The methodology involved selecting and analyzing 29 key papers published exclusively in South Korea over the last 20 years, which explore the role of advanced telemedicine technologies in facilitating remote patient monitoring and managing chronic diseases.

A significant area of focus is the advancement of "On-Device AI" technology, enabling real-time health monitoring and proactive healthcare interventions. This technology represents a substantial leap forward in telemedicine, allowing for more personalized and timely healthcare delivery. The integration of such telemedicine solutions into existing healthcare infrastructures helps overcome traditional barriers, such as limited service availability in remote areas and the challenges posed by the need for continuous connectivity.

This study also highlights the economic benefits of telemedicine, including reducing the need for in-person visits and lowering hospital readmission rates, which contribute to significant cost savings. The findings emphasize the urgent need for healthcare systems to adopt telemedicine technologies to address the evolving challenges of contemporary healthcare, particularly in the post-pandemic era.

The research concludes that integrating telemedicine offers a promising pathway toward more resilient, accessible, and efficient healthcare services. It calls for increased collaboration among policymakers, healthcare providers, and technology developers to promote the widespread adoption of telemedicine, ensuring its benefits are equitably distributed across diverse patient populations.
