Abstract
Background: South Korea is the first Asian country to adopt health technology assessment (HTA) as a tool to support decision-making concerning pricing and reimbursement of drugs in 2007. Korean traditional medicines have been continuously marginalized in the modern paradigm of evidence-based medicine. To nurture Korean medicines, clinical practice guidelines for Korean medicines have been developed through government-led initiatives, and HTAs have been applied for the National Health Insurance coverage of Korean medicines. In this study, 27 diseases were selected for analyzing the evidence development of both clinical and economic values of Korean medicines. Methods: To investigate the status quo in application of HTA in Korean medicines, reports on the cost-effectiveness analysis project comprising 27 Korean medical interventions were reviewed. Results: All the selected studies were trial-based economic appraisals and their effectiveness was estimated with a subjective judgment tool, such as the quality of life measurement or visual analog scale. This study reconfirmed the limitations of Korean medicines, which included a short observation period, nonrandomized controlled trials, small sample size, subjective assessment for efficacy, selection bias, large uncertainty, and lack of evidence. Conclusions: Priorities should be placed on establishing the clinical evidence of Korean medicines, which will serve as the base for expanding the health coverage of Korean medicines and improving satisfaction and reliability of oriental medicines in Korea's health care system. Furthermore, the need to nurture the institutional environment in which both oriental and Western medicines can collaborate in Korea should be emphasized.
