ObjectivesThe specialty of emergency medicine (EM) is experiencing a significant decrease in student interest. In addition, women are historically underrepresented within the specialty at all levels of training and practice. We sought to understand how clinical experiences and perceptions of EM influence specialty selection by medical students, particularly women.MethodsUsing a constructivist grounded theory approach, we analyzed semistructured interviews with senior medical students who considered EM as a specialty. We used purposive sampling to recruit from diverse learning environments and represent a variety of experiences. Participants reflected on their specialty selection process and experiences in EM including their perceived acceptance in the work environment.ResultsTwenty‐five medical students from 11 geographically diverse schools participated. A total of 68% (17/25) identified as women. The majority (21/25, 84%) planned on applying to EM residency. We identified four major themes: (1) distressing interpersonal interactions with patients and the ED care team negatively affect students; (2) EM culture includes behaviors that are perceived as exclusionary; (3) beliefs about the attributes of an ideal EM physician and the specialty itself have a gendered nature; and (4) ease of access to mentors, representation, and early exposure to EM environment increased interest in specialty.ConclusionsOur participants express that EM causes challenges for students to accept the norms of behavior in the field, which is an essential element in joining a group and professional identity formation. In addition, we raise concern that gendered perceptions and language may send exclusionary environmental cues that may negatively impact recruitment of a diverse physician workforce.
