Community health centers in Kenya face challenges in ensuring reliable service delivery to their populations. A systematic literature review was conducted to identify studies that utilised Bayesian hierarchical models to measure system reliability within Kenya's community health centers. The search included peer-reviewed journals, conference proceedings, and relevant grey literature published between and the present. The analysis revealed a predominance of qualitative rather than quantitative methods in evaluating system reliability, with only one study employing Bayesian hierarchical models for this purpose. While no empirical results were found due to the methodological focus on reviewing existing literature, the review highlights the need for more rigorous and standardised methodologies, particularly using Bayesian hierarchical models. Future research should prioritise the use of Bayesian hierarchical models in assessing system reliability within community health centers, alongside qualitative methods. This would enable a more robust evaluation of service delivery effectiveness. Treatment effect was estimated with logit (pᵢ) =₀+^ Xᵢ, and uncertainty reported using confidence-interval based inference.
