Introduction: this study sets out to assess the roles of Civil Society Organizations (CSOs) in post donor health project sustainability in Low and Middle Income Countries (LMICs), the case of the Bauchi State, Nigeria. This study equally investigated the CSOs strategies and roles in health project sustainability.

Methods: for quantitative data collection, the random, purposive, and convenient sampling techniques were used and 156 respondents selected from relevant organizations operating in Bauchi State, Nigeria, and 15 respondents for Key Informant Interviews (KIIs). A Semi-structured questionnaire was the study instrument, and consent from the participants as well as ethical clearances were duly obtained.

Results: the study revealed that 87.8% of the respondents indicate un-friendly operational policies, while 88.9% of them identified lack of resources (human, money and machineries) as impediments to project sustainability. Also, 74.3% of the respondents said partnership among key stakeholders and 86.6% of them affirmed that community participation and use of available (local) resources ensure health project sustainability. The study further revealed that CSOs fund health projects, support government efforts and encourage development of project sustainability road map in the state.

Conclusion: hence, health project sustainability plan should form part of a project right from inception through the donor period and thereafter. In addition to the above, internal income framework, community involvement, enabling policies and partnership among stakeholders, especially with the host government, should always guide project implementation, because without these in place, project sustainability will remain a mirage.
