Objective : This study aimed to explore the necessity of introducing an integrative curriculum between Western and Korean medicine in primary health care (PHC), with a particular focus on global health policy trends and their implications for Korea's public healthcare system. Methods : A narrative literature review was conducted by analyzing international and domestic policy documents and academic publications. Data were collected from the WHO official reports, PubMed-indexed literature, and Korean government and academic databases (KISS, RISS, NDSL). Literature selection was finalized through researcher consensus and categorized thematically for contextual analysis. Results : Five key findings emerged. First, traditional, complementary, and integrative medicine (TCIM) offers patient-centered and preventive approaches consistent with primary health care (PHC) values, though global institutionalization remains limited. Second, the United States has advanced integrative medicine (IM) education in undergraduate and residency programs, showing gains in knowledge, confidence, and clinical use. Third, Korea's efforts to introduce TCIM into medical curricula have been fragmented, while Korean medicine colleges increasingly incorporate biomedical sciences. Fourth, Korea's PHC and public healthcare setting provides a unique opportunity to pilot integrative curricula through public medical schools. Fifth, such curricula should be competency-based and reflect international principles of evidence, interprofessional teamwork, prevention, sustainability, integrative thinking, and people-centered care. Conclusion : Integrating Western and Korean medicine into PHC-oriented curricula is essential to address Korea's aging population, chronic disease burden, and health inequities. Public medical schools offer a timely platform to implement such integrative education, moving beyond fragmented attempts toward systematic, competency-based training. By aligning with global policy trends, Korea can both strengthen its public healthcare system and contribute as a leading model for integrative medical education worldwide.
