9001 Background: With an increasingly diverse patient population in the U.S., the need for a diverse clinician workforce has been exemplified. In 2021, 28% of the practicing physicians in the U.S. were born/trained outside of the continental U.S. Though strides in promoting diversity among oncologists have been made, continuous longitudinal assessments and improvements are important to ensure goals are met. We conducted the first cross-sectional study to understand the challenges and experiences of IMGs and Puerto Rican (PR) medical graduates in oncology in the U.S. Methods: An anonymous online questionnaire via Survey Monkey was developed. Non-U.S. IMGs and PRMGs who trained and/or practicing independently in the U.S. were eligible to participate. The study launched on Twitter with promotional materials, inviting participants to complete the survey. A list of IMGs and PR medical graduates was also compiled and an email invitation with the survey link was sent to. The enrollment period was from Sept-Dec 2023. Data was analyzed using descriptive statistics. Results: 97 participants from oncology-related fields completed the survey. Most were attendings (62.9%), and women (50.5%). 95.9% were IMGs and 5.2% PRMGs. 79.4% participants migrated after medical school and 90.7% were still living In the U.S. The main reasons for migrating were looking for better training (63.9%), seeking professional gains (57.7%), and lack of opportunities in their home country (49.5%). Most had to adapt to new cuisine (51.5%), community (53.6%), traditions (54.6%), and celebrations (58.8%). Participants expressed the need to change their dress code (33%), tone of voice (39.2%), the way they spoke (51.5%), and conducted themselves (49.5%). Participants faced racial/ethnic (54.5%), gender (29.7%), and language (41.9%) discrimination during training in the U.S. Similarly, they experienced racial/ethnic (46.8%), gender (32.8%), and language (24.6%) discrimination during independent practice in U.S. Most participants reported moderate personal (57%), yet extreme professional (57.4%) satisfaction in the U.S. 10.5% of participants had returned to their home country, 27.4% planned to, and 53.7% did not plan to return. The main reasons for going back home were family (67%), quality of life (28.9%), and feelings of isolation/lack of community (22.7%). Conclusions: Our study reveals that the main reasons physicians migrate to the U.S. is for education and professional opportunities. Yet these could come at a high cost, leading foreign-born physicians to compromise their true identities. Despite increasing representation of IMGs and PRMGs in the medical field in the U.S., they remain victims of discrimination at frequent rates. It is imperative to implement changes beyond diversifying the work field and strive for equity to create a more conducive environment for minority physicians.
