The Development of Health Technology Assessment in Asia: Current Status and Future Trends.

Health technology assessment (HTA) has long been employed by many countries around the world, but its adoption in Asia has been slower. Only recently have a growing number of Asian countries started to implement HTA for pricing and reimbursement decisions. The objective of this article is to provide an overview of how HTA has been or is being implemented in Asia within the context of a country's existing-and often complex-coverage, reimbursement, and pricing schemes. Three countries at different stages of HTA implementation were selected as case studies: South Korea, where there is a young yet established HTA program; Japan, where a 3-year HTA pilot program has just concluded; and China, where HTA efforts are underway but have not been formally implemented. Not only do the experiences of these 3 countries well exemplify how the organization and scope of HTA can be customized to meet a country's unique healthcare needs, but they also provide the opportunity to outline some common key challenges that must be overcome to implement and develop HTA competencies and capabilities.
