FM-Led Obstetric Units Achieve Lower C-Section Rates

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, reported lead author Emily White VanGompel, MD, of the University of Illinois College of Medicine at Chicago, and colleagues.

“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, Florida.

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.

The Model Itself Could Be the Biggest Finding

According to White VanGompel, the biggest finding from the study is the existence of the team-based model itself — where FM providers lead obstetric care with support from general surgeons.

“Quite honestly, many people around the country, including family physicians like myself, did not know [this model] existed and was thriving in these rural areas that are on the verge of becoming maternity care deserts,” White VanGompel said in an interview. “That makes a huge difference clinically because those are patients that otherwise wouldn’t have access to comprehensive pregnancy care.”

This FM-led model has the added advantage of improving continuity of care, she added, noting that issues like maternal mental health — a major contributor to postpartum morbidity and mortality — are a primary care issue.

“If we are not involved in that patient’s pregnancy care, and we don’t know that they’ve had this postpartum course or they’ve had antepartum depression, it’s very hard for us to then jump in and accurately treat that person,” White VanGompel said. “If we’re involved in the entire course of care, we can make that contribution.”

Emilio A. Russo, MD, Marie Lahasky Professor of Family Medicine and chair of the Department of Family Medicine at Louisiana State University (LSU) Health Sciences Center New Orleans, and program director of the LSU Rural Family Medicine Program, Bogalusa, Louisiana, agreed that FM providers’ more continuous care, along with experience treating both mothers and babies, make them invaluable in the maternity care setting.

“We are missing the opportunity to incorporate family physicians and nurse midwives into the continuum of care for women, especially in these remote areas,” Russo said in an interview. “Family physicians and nurse midwives are the only two [groups] in the health system trained and licensed to care for both mother and baby, and I have to believe that there’s something profoundly important about that.”

Barriers May Block FM Providers From Obstetric Practice

In a recent Birth editorial, Simone Hampton, MD, of Carle Health Family Medicine, Urbana, Illinois, explored a key question: Why aren’t we using FM to help confront the maternal mortality crisis in the United States?

Hampton described how obstetric care is often siloed between specialties and barriers, including insufficient training, organizational constraints, and malpractice coverage, deter FM physicians from practicing obstetrics.

In a written comment for this story, Hampton suggested that family doctors also face misconceptions about their ability to provide obstetric care, even with rigorous training and a comprehensive skill set.

“We are interested in caring for families,” Hampton said, emphasizing how FM providers are uniquely trained to care for the maternal dyad in a way that OBs are not and often view birth as a more natural process that typically does not require intervention.

Unfortunately, hospital administrators often maintain a different view, Brown Speights said, describing how some centers limit obstetric care privileges exclusively to OBs or require case volume minimums that can be tough to reach in a rural setting.

“If you have low-volume places, you can have a challenge meeting the numbers to keep up the requirements to get credentialed to practice obstetrics at the hospital,” she said, which only exacerbates gaps in maternity care access.

“This type of skill set in a rural place often, by default, represents a lower volume,” Russo said. “So how do the interests of competency and access intersect in this space?”

Generating more data to support the quality of FM-led obstetric models could be the clearest path forward, according to White VanGompel. She suggested that team-based approaches like the one described in the present study deserve further investigation in other hospital systems.

Until then, this gap in maternity care remains an ongoing, and often personal, concern.

“The more I do this quality work, the more I’m in these rooms where I’m the only family physician and I’m surrounded by all of these amazing labor and delivery nurses and obstetricians and maternal-fetal medicine doctors and midwives and doulas,” White VanGompel said. “I’m just constantly asking myself, Why am I the only family doctor in the room?”

This study was supported by the Agency for Healthcare Research and Quality and the North Shore Auxiliary. The Iowa Maternal Quality Care Collaborative is supported by a State Maternal Health Innovation award from the Health Resources and Services Administration. The investigators, Hampton and Brown Speights, disclosed no conflicts of interest.
