Another critical point of HIA development in Thailand is the effectiveness of influence in public policy processes. HSRI plans to develop its courses on conceptual framework and training courses for “healthy public policy advocacy” this year. The establishment of new governance structures under health system reform, designed to be a policy arena for the healthy public policy process, is highly important for the effectiveness of HIA as a policy instrument. Therefore, coordination between the development of HIA and new governance structures is absolutely crucial.
