The Association of Southeast Asian Nations (ASEAN) region is characterised by diversity. Progress towards Universal Health Coverage (UHC) and institutionalization of priority setting through Health Technology Assessment (HTA) is varied and is dependent on several country-specific factors such as the proportion of public investment in health, political support, access to good quality health information and technology infrastructure. As such, the ASEAN Secretariat requested the Health Intervention and Technology Assessment Program (HITAP), Ministry of Public Health, Thailand to survey the HTA capacity among ASEAN countries. The overarching aim of this initiative by the ASEAN Secretariat is to assist member countries in developing and streamlining their priority setting processes to improve decision-making for UHC. The objective of this survey is to explore the status and capacity of priority setting through HTA in each country in the ASEAN.
