Assessment of the design and implementation challenges of the National Health Insurance Scheme in Nigeria: a qualitative study among sub-national level actors, healthcare and insurance providers.

Sub-national governments should create legal frameworks establishing compulsory health insurance schemes at the subnational levels. Effective and efficient platforms to get the informal sector enrolled in the scheme is desirable. CBHI schemes and the currently approved state supported health insurance programmes may provide a more acceptable platform than NHIS especially among the rural informal sector. These other two should be promoted. Awareness and education should also be raised to enlighten citizens. Stakeholders need to address these gaps as well as poverty.
