Maternal care facilities in Nigeria are crucial for maternal health outcomes, but their effectiveness is often underreported and poorly understood. A mixed-methods approach combining quantitative analysis with qualitative insights was employed. Panel data estimates were used to analyse longitudinal health records from multiple facilities across Nigeria. Panel-data estimation revealed significant variations in delivery outcomes between different care facilities, suggesting a need for system-wide improvement and targeted interventions. The study highlights the importance of standardised care protocols and regular quality audits in improving maternal health outcomes in Nigerian settings. Implementing evidence-based guidelines and strengthening oversight mechanisms are recommended to enhance service delivery and patient safety.
