Community health centres play a critical role in providing accessible healthcare services in resource-limited settings such as Kenya. A difference-in-differences (DiD) model was employed to measure changes in service delivery performance over time, comparing pre- and post-intervention periods among participating centres. We observed an average improvement of 35% in patient throughput efficiency across the study period, with significant reductions in wait times for appointments. The DiD model demonstrated robustness in capturing changes attributable to policy interventions without requiring additional data collection. Policy recommendations include optimising resource allocation and enhancing training programmes for health workers to sustain observed gains in efficiency. Treatment effect was estimated with logit (pᵢ) =₀+^ Xᵢ, and uncertainty reported using confidence-interval based inference.
