Maternity care deserts — counties with no OB/GYN or midwife — affect 1 in 3 US counties and millions of women. Ob hospitalists, physicians who provide round-the-clock hospital-based obstetric care, are emerging as a key solution. Research shows hospitals with 24/7 ob hospitalist coverage have lower rates of severe maternal morbidity, and the model also offers a more sustainable career path for physicians.
Maternity care deserts — counties with zero OB/GYNs or certified nurse midwives — are spreading across the US, leaving millions of women without access to basic prenatal and delivery care. A March of Dimes report found that 1 in 3 US counties qualify as maternity care deserts, driven by workforce maldistribution, rural isolation, lower Medicaid reimbursements, and the closure of labor and delivery units. Stricter abortion laws are also deterring physicians from practicing in certain states.
Enter the ob hospitalist: a physician who works exclusively in the hospital setting, covering labor and delivery, obstetric emergencies, and patient discharge — without maintaining a private practice. The model mirrors what internal medicine hospitalists have done for decades, and it's gaining traction fast. Ob hospitalists can partner with midwives in rural communities, provide telehealth backup for high-risk cases, and offer a more sustainable work schedule (5–7 twenty-four-hour shifts per month), making the specialty more attractive to new physicians.
By the Numbers:
Why it matters: Hospitals staffed with ob hospitalists and 24/7 OB/GYN coverage show lower rates of severe maternal morbidity, per Mayo Clinic-led research. As the physician shortage worsens, this model could be a lifeline for rural communities — and for the specialty itself.
