Bayesian hierarchical models are increasingly used in medical research for their ability to account for variability across multiple levels and incorporate prior knowledge effectively. The evaluation will encompass an assessment of model specification, data quality, and implementation challenges within the context of Rwanda's healthcare delivery systems. A key finding is that the variability in resource allocation across districts significantly impacts patient outcomes; for instance, a district with lower funding saw a 15% higher risk of surgical complications compared to well-funded areas. The review underscores the importance of robust model specification and data integrity for accurate risk assessment in Rwandan hospitals. Health policymakers are advised to prioritise investment in infrastructure and training programmes, particularly in underserved districts. Treatment effect was estimated with logit (pᵢ) =₀+^ Xᵢ, and uncertainty reported using confidence-interval based inference.
