Background The 2022 Supreme Court ruling in Dobbs v Jackson Women's Health Organization nullified the constitutional right to abortion, which led to effective bans in at least 14 US states and placed obstetrics and gynecology (OB/GYN) residents in dilemmas where they may have to withhold care, potentially causing moral distress-a health care workforce phenomenon less understood among resident physicians. Objective To identify and explore moral distress experienced by OB/GYN residents due to care restrictions post-Dobbs. Methods In 2023, we invited OB/GYN residents, identified by their program directors, training in states with restricted abortion access, to participate in one-on-one, semi-structured interviews via Zoom about their experiences caring for patients post-Dobbs. We used thematic analysis to analyze interview data. Results Twenty-one residents described their experiences of moral distress due to restrictions. We report on 3 themes in their accounts related to moral distress (and 4 subthemes): (1) challenges to their physician identity (inability to do the job, internalized distress, and reconsidering career choices); (2) participating in care that exacerbates inequities (and erodes patient trust); and (3) determination to advocate for and provide abortion care in the future. Conclusions OB/GYN residents grappled with moral distress and identified challenges from abortion restrictions.
