Community health centers (CHCs) play a crucial role in delivering healthcare services in Ethiopia's rural areas. A systematic literature review was conducted using databases such as PubMed and Web of Science. Studies published between and were included, with a focus on randomized field trials in Ethiopia. In the evaluation of CHC systems, there is evidence suggesting an improvement in patient yield when implemented through a methodological approach that includes regular quality audits and feedback mechanisms (direction: increased by 15% in treatment outcomes). The review identified several methodological gaps in randomized field trials for measuring yield improvements in CHCs. Future research should adopt robust statistical models to enhance the reliability of yield improvement measurements, such as Bayesian hierarchical models with credible intervals (CI: 95%).
