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 logit (pᵢ) =₀+^ Xᵢ, and uncertainty reported using confidence-interval based inference.
