Rural clinics in Ghana face challenges in providing consistent healthcare services due to limited resources and infrastructure. A systematic literature review was conducted to assess existing methods used by rural clinics. The study employed mixed-methods approaches including surveys and observational studies. The analysis revealed that the average patient wait time at participating clinics was reduced by 20% after implementing new scheduling systems, with a confidence interval of ±5%. The findings suggest that methodological improvements in clinic systems can significantly enhance service delivery and efficiency. Rural health authorities should prioritise the adoption of evidence-based methods to streamline operations and improve patient care outcomes. rural clinics, Ghana, clinical outcomes, system evaluation, randomized field trial Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
