Community health centers in Rwanda face challenges in providing consistent clinical outcomes due to variability in service delivery and resource allocation. A mixed-methods approach combining quantitative data from standardised patient surveys with qualitative interviews to assess service delivery and patient satisfaction. The analysis revealed significant disparities in the proportion of patients receiving timely follow-up care (35%) compared to scheduled appointments (70%), highlighting areas for improvement in resource management and scheduling efficiency. Quasi-experimental design proved effective in identifying clinical outcomes gaps within community health centers, providing actionable insights for policy reform and resource allocation. Implement targeted interventions focusing on improving appointment scheduling and timely follow-up care to enhance patient satisfaction and service delivery quality. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
