Adoption rates of new healthcare interventions in Ghanaian district hospitals have been underreported due to methodological challenges. A Bayesian hierarchical model was applied to analyse adoption data from 10 district hospitals in Ghana. The model accounts for hospital-specific and district-level variability. Bayesian estimates indicated higher adoption rates (35% confidence interval: 28-42%) compared to previous non-hierarchical methods, highlighting significant variation between districts. The Bayesian hierarchical model provides a more nuanced understanding of intervention adoption patterns in Ghanaian district hospitals and can be applied to other healthcare settings. Policy-makers should consider using the proposed model for future assessments to ensure accurate reporting and effective resource allocation.
