ImportanceFollowing the Dobbs v Jackson Women’s Health Organization decision in June 2022, 17 US states have functionally banned abortion except in narrow circumstances, and physicians found in violation of these laws face felony charges, loss of their medical license, fines, and prison sentences. Patient impacts are being studied closely, but less research has focused on the consequences for obstetrician-gynecologists (OB-GYNs), for whom medically necessary care provision may now carry serious personal and professional consequences.ObjectiveTo characterize perceptions of the impact of abortion restrictions on clinical practice, moral distress, mental health, and turnover intention among US OB-GYNs practicing in states with functional bans on abortion.Design, Setting, and ParticipantsThis qualitative study included semistructured, remote interviews with OB-GYNs from 13 US states with abortion bans. Volunteer sample of 54 OB-GYNs practicing in states that had banned abortion as of March 2023.ExposureState abortion bans enacted between June 2022 and March 2023.Main Outcomes and MeasuresOB-GYNs’ perceptions of clinical and personal impacts of abortion bans.ResultsThis study included 54 OB-GYNs (mean [SD] age, 42 [7] years; 44 [81%] female participants; 3 [6%] non-Hispanic Black or African American participants; 45 [83%] White participants) who practiced in general obstetrics and gynecology (39 [72%]), maternal-fetal medicine (7 [13%]), and complex family planning (8 [15%]). Two major domains were identified in which the laws affected OB-GYNs: (1) clinical impacts (eg, delays in care until patients became more sick or legal sign-off on a medical exception to the ban was obtained; restrictions on counseling patients on pregnancy options; inability to provide appropriate care oneself or make referrals for such care); and (2) personal impacts (eg, moral distress; fears and perceived consequences of law violation; intention to leave the state; symptoms of depression and anxiety).Conclusions and relevanceIn this qualitative study of OB-GYNs practicing under abortion bans, participants reported deep and pervasive impacts of state laws, with implications for workforce sustainability, physician health, and patient outcomes. In the context of public policies that restrict physicians’ clinical autonomy, organization-level supports for physicians are essential to maintain workforce sustainability, clinician health and well-being, and availability of timely and accessible health care throughout the US.
