Objective: Understand the impact of a Big Sibling mentorship program on medical students and surgery residents.

Design: Structured mentorship pairings followed by survey analysis

Setting: Medical student surgery clerkship at a single academic hospital from July 2019 to December 2020.

Participants: Medical students on their surgery clerkship and surgical research residents

Intervention: Medical students on their surgery clerkship were paired with a Big Sibling, a surgical research resident, based on mutual interests. The resident mentor contacted the student via email and additional contact was at the student"s discretion.

Outcome: Participation in and perceptions of the program and clerkship were assessed with a post-clerkship survey.

Results: 81 medical students and 34 residents participated with a 79% and 96% survey response rate, respectively. 73% of students interacted with their Big Sibling with a total of 182 interactions. The most valuable topics discussed included ward skills, personal development and career advising. Students who interacted >2 times with their Big Sibling were more likely to perceive the operating room as a positive learning environment, view attendings as role models, and receive mentoring and feedback from residents and attendings (p=0.03, 0.02, 0.01 respectively). 78% of residents thought the program was a positive experience and no residents found it burdensome.

Conclusion: The Big Siblings program enhances the surgery clerkship learning environment. Medical students who engaged with their Big Sibling had a more positive view of the clerkship and the mentorship provided by residents and attendings. Future research will assess if this program leads to enhanced surgical career interest.
