Community health centres in Ethiopia have been established to improve healthcare access and quality. However, their effectiveness varies over time. A longitudinal study will employ a Difference-in-Differences approach to assess changes in service delivery and patient outcomes between two groups: those with pre-existing effective health centres and new ones established post-. The DiD model will account for potential confounders such as socioeconomic factors and regional variations. The analysis revealed a significant increase in healthcare utilisation among the new community health centre populations, indicating improved access to services. This study provides robust evidence supporting the efficacy of newer community health centres in Ethiopia. The DiD model successfully captured temporal trends without confounding factors. Future policy should prioritise resource allocation towards under-resourced areas and continue monitoring for sustainability and scalability. Treatment effect was estimated with logit (pᵢ) =₀+^ Xᵢ, and uncertainty reported using confidence-interval based inference.
