Community health centers in Rwanda face challenges in maintaining consistent service delivery, necessitating a systematic assessment of their reliability. A randomized control trial was conducted to assess the consistency and efficiency of community health centers in delivering healthcare services; 100 randomly selected health centers were evaluated over a six-month period, with data collected on service availability and patient satisfaction. The analysis revealed that 85% of health centers consistently met their scheduled service times, indicating high reliability. Patient satisfaction scores averaged at 79%, suggesting room for enhancement in service quality. The randomized field trial demonstrated the feasibility of assessing community health centre systems' reliability and provided actionable insights to improve service delivery. Implementing regular performance evaluations and training programmes tailored to specific areas of weakness could enhance service reliability and patient satisfaction. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
