Methodological Evaluation of Community Health Centre Systems in Ethiopia: A Randomized Field Trial for Yield Improvement

Community health centers (CHCs) play a crucial role in primary healthcare delivery in Ethiopia, particularly for rural and underserved populations. A mixed-methods approach was employed to assess the impact of CHCs on health outcomes, including quantitative surveys and qualitative interviews. Data were analysed using logistic regression models with robust standard errors for statistical inference. The analysis revealed a significant increase (p < 0.05) in patient consultation rates from baseline levels by 25% within the first year of implementation. CHCs have demonstrated potential to enhance service yield, but further improvements are needed to address unmet health needs. Continuous quality improvement initiatives and enhanced training programmes for CHC staff should be prioritised to maximise their impact on patient care delivery.
