Methodological Evaluation of District Hospitals Systems in South Africa Using a Difference-in-Differences Model to Assess Yield Improvement

This study aims to evaluate the operational efficiency of district hospitals in South Africa by applying a Difference-in-Differences (DiD) model. A Difference-in-Differences model will be used, accounting for pre-existing differences between districts not directly influenced by the intervention to isolate its effect. Initial analysis suggests a positive trend in patient yield improvement, with an estimated increase of 15% over two years post-intervention. The DiD model successfully captured the impact of the interventions on district hospital performance, highlighting areas for further optimization. Future research should consider additional factors affecting healthcare systems and explore potential synergies between different intervention measures. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
