Methodological Evaluation of Community Health Centre Systems in Kenya: A Randomized Field Trial for Measuring Clinical Outcomes

Community health centers in Kenya are pivotal for providing accessible healthcare services to underserved populations. A meta-analysis was conducted using data from multiple randomized controlled trials (RCTs) across Kenya. The analysis employed a mixed-effects model to account for variability between studies and within studies. Vaccination coverage rates varied significantly, with one study reporting an average coverage rate of 85% among participating communities. The mixed-effects modelling approach enhanced the reliability of our findings by accounting for both fixed effects (e.g., community characteristics) and random effects (e.g., differences between studies). Further research should focus on improving logistical support to ensure consistent vaccine supply in rural settings. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
