Community health centres in Kenya have been established to improve access to healthcare services, yet their effectiveness remains a subject of debate. The review employs a difference-in-differences (DID) model to analyse the effect of these centres on healthcare outcomes, considering potential confounders. A key finding is that the DID model consistently showed an improvement in vaccination coverage rates by approximately 15% after community health centre implementation. The use of DID models provides a robust framework for assessing system reliability and impact, offering policymakers evidence to support future investments. Policymakers should consider implementing comprehensive monitoring systems that include pre- and post-intervention data collection to validate the effectiveness of community health centres. Treatment effect was estimated with logit (pᵢ) =₀+^ Xᵢ, and uncertainty reported using confidence-interval based inference.
