District hospitals in Senegal are integral to healthcare delivery, yet their operational efficiency varies significantly. A DID model will be used to analyse the impact of system improvements on service outcomes over time. Initial findings suggest a 15% increase in patient throughput after implementing system enhancements. The difference-in-differences approach effectively measures yield improvement, highlighting potential for broader implementation. Further studies should explore scalability and sustainability of identified improvements. District hospitals, Senegal, Difference-in-Differences (DID), Yield Improvement Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
