Maternal care facilities in Ghana are crucial for improving maternal health outcomes, yet their effectiveness varies significantly across different regions. A mixed-methods approach was employed, including quantitative panel-data regression analysis with robust standard errors to evaluate the impact of maternal care on health outcomes. The panel data revealed a significant positive correlation between the number of trained healthcare personnel and reduced maternal mortality rates (p < 0.05), suggesting that adequate staffing is essential for improving clinical outcomes. This study provides robust evidence supporting the importance of well-trained healthcare professionals in maternal care facilities to enhance clinical effectiveness. Healthcare authorities should prioritise training and resource allocation to ensure a sufficient number of skilled personnel in maternal care units across Ghana. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
