Redução das taxas de parto cesáreo nas comunidades rurais dos EUA: Revisão sistemática das intervenções e abordagens de cuidado

Resumo original em inglês

O que aconteceu

Cesarean deliveries are the most common major surgery in the US, with rates rising disproportionately in rural communities. While sometimes medically necessary, unnecessary cesarean births increase risks for maternal death, long-term complications, and intergenerational health effects that contribute to the burden of chronic disease. This systematic review examined studies describing interventions and approaches to care that reported outcomes related to reducing cesarean delivery rates in rural US communities.

We searched 4 databases in September 2025. Studies were eligible if they were conducted in rural US settings and reported cesarean-related outcomes associated with an intervention or care approach. We categorized interventions as patient level, provider level, or health system level. Two reviewers independently screened articles for inclusion, extracted data, and assessed study quality using the Newcastle-Ottawa Scale and the Joanna Briggs Institute checklist.

O que encontraram

Nine studies met inclusion criteria. Of the 2 patient-level interventions, psychosocial education was associated with lower cesarean delivery rates (21% in intervention vs 40% in control), whereas a mobile health application showed only a marginal difference (27.1% among application users vs 27.7% among nonusers). None were categorized at the provider level. Seven interventions tested system-level models, primarily comparing hospitals with different staffing patterns; family medicine-led hospitals had lower rates of low-risk nulliparous, term, singleton, vertex cesarean delivery than hospitals staffed by both family medicine physicians and obstetricians (23% vs 28%), certified nurse-midwife-managed births had lower cesarean delivery rates than family medicine physician-managed births (8% vs 14%), and collaborative maternity care models integrating midwives, nurses, and obstetricians were associated with cesarean delivery rates declining from 26.2% to 11.2%.

Por que isso importa

System-level approaches, particularly those that restructure maternity care teams, emphasize family medicine physician-led models, and integrate midwifery and culturally grounded childbirth practices, are more consistently associated with lower cesarean delivery rates in rural US settings than patient-level interventions alone. Future efforts to reduce unnecessary cesarean deliveries should prioritize strategies tailored to the variability of rural care capacity.
