Background: To improve the performance of the healthcare system, Mali’s government implemented a pilot project of performance-based financing (PBF) in the field of reproductive health. It was established in the Koulikoro region. This research analyses the process of implementing PBF at district hospital (DH) level, something which has rarely been done in Africa. Methods: This qualitative research is based on a multiple, explanatory, and contrasting case study with nested levels of analysis. It covered three of the 10 DHs in the Koulikoro region. We conducted 36 interviews: 12 per DH with council of circle’s members (2) and health personnel (10). We also conducted 24 non-participant observation sessions, 16 informal interviews, and performed a literature review. We performed data analysis using the Consolidated Framework for Implementation Research (CFIR). Results: Stakeholders perceived the PBF pilot project as a vertical intervention from outside that focused solely on reproductive health. Local actors were not involved in the design of the PBF model. Several difficulties regarding the quality of its design and implementation were highlighted: too short duration of the intervention (8 months), choice and insufficient number of indicators according to the priority of the donors, and impossibility of making changes to the model during its implementation. All health workers adhered to the principles of PBF intervention. Except for members of the district health management team (DHMT) involved in the implementation, respondents only had partial knowledge of the PBF intervention. The implementation of PBF appeared to be easier in District 3 Hospital compared to District 1 and District 2 because it benefited from a pre-pilot project and had good leadership. Conclusion: The PBF programme offered an opportunity to improve the quality of care provided to the population through the motivation of health personnel in Mali. However, several obstacles were observed during the implementation of the PBF pilot project in DHs. When designing and implementing PBF in DHs, it is necessary to consider factors that can influence the implementation of a complex intervention.

Introduction: Numerous sub-Saharan African countries have experimented with performance-based financing (PBF) with the goal of improving health system performance. To date, few articles have examined the implementation of this type of complex intervention in Francophone West Africa. This qualitative research aims to understand the process of implementing a PBF pilot project in Mali's Koulikoro region. Method: We conducted a contrasted multiple case study of performance in 12 community health centres in three districts. We collected 161 semi-structured interviews, 69 informal interviews and 96 non-participant observation sessions. Data collection and analysis were guided by the Consolidated Framework for Implementation Research adapted to the research topic and local context. Results: Our analysis revealed that the internal context of the PBF implementation played a key role in the process. High-performing centres exercised leadership and commitment more strongly than low-performing ones. These two characteristics were associated with taking initiatives to promote PBF implementation and strengthening team spirit. Information regarding the intervention was best appropriated by qualified health professionals. However, the limited duration of the implementation did not allow for the emergence of networks or champions. The enthusiasm initially generated by PBF quickly dissipated, mainly due to delays in the implementation schedule and the payment modalities. Conclusion: PBF is a complex intervention in which many actors intervene in diverse contexts. The initial level of performance and the internal and external contexts of primary healthcare facilities influence the implementation of PBF. Future work in this area would benefit from an interdisciplinary approach combining public health and anthropology to better understand such an intervention. The deductive-inductive approach must be the steppingstone of such a methodological approach.
