Maternal care facilities in Ethiopia play a crucial role in improving maternal health outcomes, yet their effectiveness is not well understood due to limited data and methodological challenges. The study employed a fixed effects model using longitudinal patient data from multiple facilities across Ethiopia. Robust standard errors were incorporated to account for potential heteroscedasticity and autocorrelation within the dataset. A significant proportion (35%) of maternal care episodes resulted in adverse outcomes, with variations observed between different regions and facilities. The fixed effects model provided insights into the variability of clinical performance across Ethiopian maternal care systems. Future research should focus on strengthening quality control measures to enhance patient safety and efficacy. Immediate implementation of a standardised training programme for healthcare providers in high-risk areas is recommended, alongside continuous monitoring of facility adherence to best practices.
