The global rise in cesarean section (CS) rates has become a significant public health concern, particularly due to the increasing prevalence of non-medically indicated procedures. Unnecessary cesarean deliveries are associated with heightened maternal and neonatal risks, increased healthcare costs, and long-term reproductive complications. Nurses and midwives play a pivotal role in maternity care and are strategically positioned to influence clinical decision-making, maternal education, and labor support practices. This article critically examines the effectiveness of nurse-led interventions in reducing unnecessary cesarean deliveries through a comprehensive review of empirical evidence published within the last decade. Key nurse-led strategies explored include structured antenatal education programs, psychosocial and relaxation-based interventions, midwife-led models of care, audit and feedback mechanisms, and interprofessional communication initiatives. The findings indicate that nurse-led antenatal education enhances maternal knowledge, self-efficacy, and confidence in vaginal birth, while continuous labor support and effective communication contribute to reduced elective and emergency cesarean rates among low-risk populations. Midwife-led continuity models demonstrate consistent associations with higher rates of spontaneous vaginal births and lower intervention use. Despite variations in intervention design and methodological limitations across studies, the overall evidence supports the integration of nurse-led interventions as a viable strategy for optimizing childbirth outcomes and promoting evidence-based maternity care. Strengthening nursing leadership in obstetric practice and policy development may contribute significantly to reducing unnecessary cesarean deliveries and improving maternal-neonatal health outcomes.
