Systematic Review Of Nursing Interventions To Reduce Unnecessary Cesarean Section Rates: A Global Perspective

Abstract

Background: The global rise in cesarean section (CS) rates, often exceeding the World Health Organization’s recommended threshold of 10–15%, represents a critical public health challenge. While lifesaving when medically indicated, unnecessary cesarean deliveries are associated with increased maternal and neonatal morbidity, compromised future reproductive health, and escalating healthcare costs. Nurses and midwives, as the primary providers of continuous intrapartum care, are uniquely positioned to influence birth outcomes through physiological support and advocacy.

Objective: To systematically review and synthesize peer-reviewed evidence regarding the effectiveness of nursing interventions—including continuous labor support, biomechanical positioning, antenatal education, and organizational staffing models—in reducing unnecessary cesarean section rates across diverse global healthcare settings.

Methods: A comprehensive systematic review was conducted adhering to PRISMA 2020 guidelines. Data were synthesized from randomized controlled trials, quasi-experimental studies, and comparative observational studies published between 2010 and 2025. The review integrates findings from high-income countries (HICs) and low- and middle-income countries (LMICs) to provide a nuanced global perspective.

Results: The synthesis identifies that continuous labor support (one-to-one nursing) significantly reduces the likelihood of cesarean delivery (RR 0.75). Biomechanical interventions, specifically the use of the peanut ball for women with epidural analgesia, reduced the first stage of labor by approximately 53 minutes and lowered CS rates (RR 0.74). Organizational factors, particularly adherence to nurse-staffing standards, were independent predictors of lower surgical birth rates. Contextual barriers such as medical hierarchies and resource constraints significantly modulate intervention efficacy.

Conclusion: Nursing interventions are not merely adjunctive but central to the strategy of de-medicalizing childbirth. Implementing evidence-based nursing practices, supported by adequate staffing and interdisciplinary collaboration, is essential to reversing the trend of unnecessary cesareans globally.
