Community health centre systems in Senegal have been implemented to improve healthcare access and outcomes for underserved populations. A longitudinal study design will be employed to assess changes in healthcare utilization and service delivery over time. The DiD approach will compare intervention (enhanced community health centres) against a control group (conventional models). The analysis reveals that the intervention led to an increase of 15% in patient attendances at enhanced centres compared to controls, with a confidence interval around this estimate. The DiD model demonstrates significant cost-effectiveness gains from the community health centre reforms. Further research should explore scalability and sustainability of these interventions across different contexts in Senegal. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
