Abstract
BACKGROUND: Countries in sub-Saharan Africa, including Nigeria, continue to depend on donor funding to achieve their national HIV response goals. The Government of Nigeria has made limited progress in translating political commitment to reduce donor dependency into increased domestic investment to ensure the sustainable impact of the HIV response. We explored the context-specific factors affecting the financial sustainability of the HIV response in Nigeria. METHODS: Between November 2021 and March 2022, we conducted document reviews (n=13) and semistructured interviews with purposively selected national and subnational stakeholders (n=35). Data were analyzed thematically using the framework of health financing functions comprising revenue generation, pooling, and purchasing. RESULTS: Stakeholders reported that there is a low level of government funding for the HIV response, which has been compounded by the weak engagement of Ministry of Finance officials and the unpredictable and untimely release of budgeted funds. Opportunities for domestic funding include philanthropy and an HIV Trust Fund led by the private sector. Integration of HIV treatment services into social health insurance schemes has been slow. Commodity purchasing has been inefficient due to ineffective coordination. Government stakeholders have been reluctant to support one-stop-shop facilities that target key and priority populations. CONCLUSION: Opportunities exist in the government and private sectors for improving domestic health financing to support transitioning from donor support and ensuring the financial sustainability of the HIV response in Nigeria. To ensure that domestic financing for the HIV response is stable and predictable, the amount of domestic funding needs to increase and a framework that incorporates donor transition milestones must be developed, implemented, and monitored.
