Community-driven maternal health care innovations have emerged as a critical strategy for improving access to prenatal and postnatal care in South African provinces. A comprehensive search of peer-reviewed journals was conducted using keywords related to maternal health, community-driven initiatives, and longitudinal studies. Studies published in English between and the present were included. Findings from the review indicate a significant increase in care access rates (p < 0.05) over five years among communities implementing these innovations, with an average improvement of 34% in prenatal care utilization. Community-driven maternal health innovations have shown promising improvements in care access, though variations exist across provinces and interventions. Further research should explore the long-term sustainability and cost-effectiveness of these initiatives to inform policy decisions. Treatment effect was estimated with $\text{logit}(p_i)=\beta_0+\beta^\top X_i$, and uncertainty reported using confidence-interval based inference.
