The proposed study would explore Sri Lanka’s health funding policy engagement, instead of pure research that only generates evidence. It would further identify policy issues that should be on top of policymakers’ agenda to get Sri Lanka prepared for the donor transition, and to build more bridges between the Ministry of Health (MOH) and the Ministry of Finance (MOF) to coordinate the transition. Based on the ‘knowledge, capacity, policy (KCP) gaps framework developed by the Center for Policy Impact in Global Health (CPIGH) at Duke University, this study will help to create a better understanding of the specific gaps in each country, support the development of policy solutions to help close the gap, and engage in evidence-to-policy translation. IPS has identified the lack of data and knowledge for strategic planning, efficiency improvement and prioritisation of sustainable health finance as a major gap in transition planning.
