Community health centers in Ethiopia face challenges related to service delivery efficiency. A randomized controlled trial (RCT) was conducted among 100 community health centres across Ethiopia. Participants were randomly assigned to either an intervention group or control group. Initial analysis indicated a significant increase in service delivery efficiency by 25% in the intervention groups compared to controls, with a 95% confidence interval of [18%, 32%]. The trial demonstrated that targeted interventions can enhance community health centre performance. Further research should explore scalability and cost-effectiveness of these interventions across different regions in Ethiopia.
