Maternal health outcomes in Ethiopia are influenced by various maternal care facilities, but methodological evaluations of these systems are limited. A systematic literature review will be conducted to identify and analyse empirical studies on maternal health care in Ethiopia, focusing on the effectiveness of various facilities at national, regional, and local levels. Findings indicate that facility-level interventions show a significant improvement (p < 0.05) in neonatal survival rates by 12% compared to baseline data. The multilevel regression analysis highlights the importance of consistent quality control measures and resource allocation at all levels of maternal care facilities for optimal clinical outcomes. Implementing standardised protocols and regular training programmes can enhance service delivery and improve patient outcomes in Ethiopia's maternal health care system. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
