Bayesian Hierarchical Model for Evaluating Community Health Centre Systems in Tanzania
Bayesian hierarchical models are increasingly used in health research to analyse complex data structures, particularly in resource-limited settings like Tanzania where interventions often need careful evaluation. A Bayesian hierarchical linear regression model was employed, accounting for variability across CHCs and within each centre. Uncertainty quantification was achieved through posterior predictive checks and credible intervals. The analysis revealed a significant proportion (p < 0.05) of yield improvement in CHCs when implemented with improved referral protocols, indicating potential for systemic enhancement. This study provides evidence supporting the efficacy of specific interventions within CHC systems in Tanzania and offers insights into how these models can be applied to other settings. Future research should validate findings using larger datasets and explore scalability across different geographical regions. Policy recommendations include promoting best practices through training and standardisation. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.

Methodological Evaluation of Community Health Centre Systems in Uganda Using Multilevel Regression Analysis for Adoption Rates
Community health centres in Uganda have been established to improve access to healthcare services among rural populations. However, their effectiveness varies across different regions and contexts. A systematic review was conducted, summarizing data from multiple studies on community health centres within Uganda. Multilevel regression analysis was applied to examine the impact of various contextual variables on adoption rates at both individual (patient) and aggregate (system) levels. The multilevel regression model revealed that financial support from external donors significantly increased the adoption rate of community health centre systems, with a coefficient estimate of +0.35 (95% CI: [0.12, 0.58]). This study provides insights into optimising the implementation and sustainability of community health centres in Uganda. Health policymakers should prioritise financial support for community health centres to enhance their adoption rates and effectiveness.

Retention Rates and Impact of Traditional Birth Attendants in Tanzanian Rural Healthcare Systems on Maternal Mortality Reduction
Traditional Birth Attendants (TBAs) play a significant role in maternal healthcare in Tanzanian rural areas, yet their effectiveness and integration into formal health systems remain under-researched. A mixed-methods approach including surveys, interviews, and observational studies was employed to evaluate TBA performance and patient outcomes. TBAs maintained a consistent presence in healthcare facilities with a retention rate of 85% over three years. However, their direct intervention reduced maternal mortality by an average of 12%, though the impact varied significantly across different regions. The study highlights the importance of TBAs in rural healthcare and suggests that enhanced training could further improve their effectiveness in reducing maternal deaths. Rural health authorities should prioritise retaining and supporting TBAs while also investing in community education programmes to complement TBA services.
