Community health centers in Uganda are critical for delivering healthcare services to underserved populations. However, their operational efficiency varies significantly. A randomized controlled trial was conducted among 100 randomly selected health centers. Data collected included patient flow, resource utilization, and service outcomes. Statistical analysis used a linear regression model to assess efficiency gains. The study revealed that the implementation of targeted interventions led to an average increase in patient throughput by 25% (95% CI: 18-32%). Our findings suggest that strategic adjustments can significantly improve operational efficiency, supporting better health outcomes for underserved communities. Health authorities should prioritise the replication of successful interventions and further research to refine strategies.
