Clinical outcomes in Ethiopian community health centres are often suboptimal, necessitating a robust method for assessing their performance and identifying areas for improvement. A Bayesian hierarchical model was developed to estimate clinical outcomes, accounting for variability across different health centres. Data from multiple sources were integrated into the model to ensure comprehensive coverage of performance metrics. The model indicated that intervention effectiveness varied significantly by health centre type, with some showing substantial improvements in patient recovery rates compared to baseline levels (e.g., a 15% increase in recovery for certain conditions). This study underscores the importance of tailored interventions and targeted support within Ethiopian community health systems. Health authorities should prioritise resource allocation towards high-impact areas identified by the model, aiming to improve clinical outcomes across all centres. Bayesian Hierarchical Model, Community Health Centres, Clinical Outcomes, Ethiopia Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
