Community health centers in Nigeria have been established to address healthcare disparities among underserved populations. A longitudinal study employing a quasi-experimental design was conducted within a Nigerian context. Data collection involved surveys and administrative records from to. The analysis revealed that the implementation of preventive healthcare programmes significantly reduced treatment costs by 5 per patient while improving health outcomes. Quasi-experimental designs offer a robust method for assessing cost-effectiveness in community health centre systems, particularly when longitudinal data are available. Future research should expand the study to include additional communities and incorporate feedback mechanisms from patients to enhance service delivery. Treatment effect was estimated with logit (pᵢ) =₀+^ Xᵢ, and uncertainty reported using confidence-interval based inference.
