As of 2020, maternal and infant health in the US has worsened. At the same time, the number of health professionals available to manage female health issues is changing; the number of physicians in obstetrics and gynecology (Ob-Gyn) and midwives is decreasing, whereas the number of Ob-Gyn physician associates (PAs) is growing. We analyzed PAs practicing in the Ob-Gyn discipline, drawing on the PA Professional Profile, a database maintained by the National Commission on Certification of PAs. In 2021, there were 1,322 Ob-Gyn PAs (1.2% of all clinically active PAs). This health profession has grown by 66.9% since 2013, when only 792 PAs practiced in this specialty. As of 2021, their median age was 38, and 98.0% were female (70.1% of all PAs were female). The practice setting was between office (54.7%) and hospital (34.0%) employment, with 11.3% described as “other.” In 2021, the median annual income of Ob-Gyn PAs was $105,000. With the reduction of obstetrician-gynecologists, the relative growth of PAs in this area of medicine and surgery is a natural part of the solution to the projected obstetrical physician deficit.Copyright © 2024 Melissa A.
