BackgroundSpending on preventive care in low- and middle-income countries (LMICs), including Indonesia, is much lower than spending on curative care. There has been a pressing need to develop a clear pathway to increase spending on preventive care. This study aimed to assess the current financing landscape for health promotion and disease prevention in Indonesia and, subsequently, to develop a framework and recommendations for future health promotion financing in the country.MethodsWe adopted a mixed-method approach to gather information from all relevant stakeholders from December 2022 to June 2023. For the qualitative approach, we conducted (a) in-depth interviews (IDIs) and (b) focus group discussions (FGDs) with government officials at national and district levels, academics, professional organizations, healthcare workers in primary healthcare centres (PHCs), community health volunteers, non governmental organizations and private companies. For the quantitative approach, we applied a national online survey to healthcare workers involved in health promotion in PHCs. IDIs and FGDs were conducted with purposefully selected resource persons at the national level, five selected districts across Indonesia, and within 15 primary health offices and their communities. All qualitative data were recorded, transcribed, coded, interpreted, and then triangulated with national survey findings to develop the financing framework.ResultsWe identified gaps between the theory and practice of health promotion and disease prevention. These included the limited scope of health promotion initiatives, lack of direction and coordination between ministries, agencies and government levels, limited availability and capacity of health promoters, various yet uncoordinated funding resources and inflexibility in using the funds. To bridge the gap, the framework we developed suggests strengthening the legal and regulatory basis, strategically prioritizing financing arrangements, promoting evidence-based health promotion activities, developing the capacity of health promoters, enhancing the health financing information system and improving monitoring and evaluation.ConclusionsIdentified gaps and challenges in health promotion and disease prevention initiatives inform the development of our framework for future health promotion financing. This framework assists the national government in organizing national health promotion financing strategies and potentially serves as a valuable model for other LMICs.
