Labor and delivery centers run by family medicine (FM) healthcare providers have a lower cesarean delivery rate and better safety culture than centers led by obstetricians (OBs), based on observational data from Iowa hospitals.
These findings show how FM providers backed up by general surgeons can deliver a high standard of obstetric care, suggesting that this team-based model could address growing maternity care deserts across the United States, lead author Emily White VanGompel, MD, of the University of Illinois College of Medicine in Chicago, and colleagues reported.
“Despite decades of research documenting the high quality of care provided by FM physicians, controversy continues regarding whether family physicians trained in existing FM residency programs should provide intrapartum obstetric care,” the investigators wrote in Annals of Family Medicine.
This controversy, though long-standing, has gained more attention in the past decade with worsening severe maternal morbidity and maternal health disparities in rural areas, along with state-based perinatal quality initiatives to improve care and reduce severe maternal morbidity. These efforts have largely involved obstetric, nursing, and midwifery organizations, with minimal input from FM professionals.
The role of FM in these initiatives therefore remains unexplored.
This is a clear blind spot, according to White VanGompel and colleagues, who noted that 40% of counties in the United States do not have an OB or a midwife, while only 6.5% of counties lack an FM physician. In other words, FM providers may be the most rational — and widely available — specialty to close gaps in obstetric care.
Study Reveals Fewer C-Sections, Better Safety Culture Among FM-Led Centers
To explore the viability of an FM-led model, the investigators used a cross-sectional survey to assess the relationship between staffing models and perinatal outcomes. A total of 849 clinicians, including physicians, nurses, and midwives from 39 hospitals, were surveyed as part of a statewide quality improvement initiative designed to reduce cesarean delivery rates. The hospitals were categorized on the basis of the type of physician providing intrapartum care: Some hospitals were staffed exclusively by FM physicians (13), some by OBs only (11), and others by both types of providers (15).
The primary outcome measured was the low-risk cesarean delivery rate, specifically the nulliparous, term, singleton, vertex cesarean delivery rate.
The study found that FM-only hospitals, all of which were located in rural areas with fewer than 1000 annual births, had significantly lower cesarean delivery rates than hospitals with mixed or OB-only staffing. After adjusting for factors such as hospital birth volume, geographic location, patient body mass index, maternal age, and insurance status, FM-only hospitals had an adjusted 34.3% lower rate of cesarean sections than hospitals with both FM and OB physicians (adjusted incidence rate ratio, 0.66; 95% CI, 0.52-0.98).
In addition to lower cesarean delivery rates, the study revealed that hospitals staffed exclusively by FM physicians reported a stronger safety culture, as measured by nurse perceptions of unit norms supporting vaginal birth. Nurses at FM-only hospitals were more likely to endorse safety practices that favored vaginal delivery, a finding that was statistically significant. The study also found that nurses at FM-only hospitals rated overall unit safety culture higher than those at hospitals staffed solely by OBs or a combination of FM physicians and OBs.
“I’m not surprised [by these findings],” said Joedrecka S. Brown Speights, MD, professor and chair of the Department of Family Medicine and Rural Health at Florida State University College of Medicine, Tallahassee.
She noted that the data echo previous reports demonstrating the broader benefits of FM involvement.
“When people get primary care, life is better,” Brown Speights said, citing improved outcomes, greater health equity, and lower overall healthcare costs associated with high-quality primary care.
“That’s what we need for women and for pregnant persons, especially in rural areas,” she said.
