Abstract
Rural clinics in Ghana face challenges related to clinical outcomes due to limited resources and infrastructure. A Bayesian hierarchical model was employed to analyse clinical outcomes data from multiple rural clinics. The model accounts for both clinic-level heterogeneity and shared variability among clinics, providing a robust estimation framework for evaluating clinical performance metrics such as patient recovery rates and diagnostic accuracy. Bayesian inference indicated that the average clinic-level patient recovery rate was 78% with a 95% credible interval of (76%, 80%), highlighting significant variability in outcomes across different clinics. The Bayesian hierarchical model effectively captured both within-clinic and clinic variations, offering insights into improving rural healthcare systems' clinical performance through targeted interventions. Policy recommendations include the development of standardised training programmes for clinic staff to enhance diagnostic accuracy and patient recovery rates, along with increased funding for infrastructure improvements in underserved areas.
