Problem Physicians' voices are valued in society and should be present in mainstream social media where they can provide valuable public health messaging and patient education as well as increase opportunities for medical education, mentoring, and collaboration. However, lack of formal education on effective use of social media prevents many physicians from using it. Approach The authors developed a physician-led social media training program to address the need for formal instruction on social media use. The program was presented to medical students, trainees, and faculty at an academic medical institution in August and September 2020. The virtual format included 5 hour-long sessions with presentations by peer experts in social media. Peer physicians with experience using social media presented on a range of topics, including introductions to platforms, how to reach and grow audiences, and use of social media to advance patient education, medical education, and advocacy. Outcomes There were 425 cumulative registrations for the 5 sessions of the Social Media Summit. The number of registrants increased for each session, suggesting that interest increased over time. Qualitative and quantitative participant feedback was collected via a brief, voluntary survey. All of the participants who completed the survey (n = 24) reported they were "very satisfied" (58.3%) or "somewhat satisfied" (41.7%) with the Summit. Next Steps Physician involvement in social media presents opportunities for public health knowledge, medical education, scientific collaboration, and career advancement. Physicians who have been successful in using social media for these purposes are excellent peer educators and can fill the medical education void in social media training. Future plans include building sustainability of the program, collecting additional quantitative and qualitative feedback to guide improvement, and encouraging reproducibility.
