Community health centres in Ghana face challenges related to efficiency, necessitating a methodological evaluation to identify best practices and potential improvements. The study will employ a mixed-methods approach including quantitative surveys and qualitative interviews to assess the operational efficiency of selected health centres. Data will be analysed using statistical models to evaluate performance metrics and inferential statistics to quantify uncertainty in findings. A preliminary analysis suggests an improvement rate of 15% in service delivery times across randomly selected health centres, indicating potential for enhanced patient care through targeted interventions. The randomized field trial will provide valuable insights into the operational efficiency of Ghana's community health centre systems, offering a roadmap for future improvements and policy recommendations. Based on findings from this study, specific areas such as resource allocation, staff training programmes, and patient flow management strategies should be prioritised to improve service delivery effectiveness. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
