Medical professionals use social media for career development, education, clinical outreach, or advocacy. Prior studies estimate that 25% to 65% of health care providers use social media professionally; however, the number of users and platforms are rapidly changing. Therefore, as part of a broader study, we set out to assess platform preferences and social media usage among neurologists. This was a multisite cross-sectional analysis consisting of a REDCap survey of clinicians, residents, and medical students. Faculty, trainees, or clinical year medical students interested in child neurology or adult neurology residency or fellowship programs within the United States were eligible to participate. Recruitment methods were broad to encompass as diverse and extensive participation as possible. Results were analyzed using descriptive statistics. Data are presented according to the STROBE guidelines. Of the 226 neurology respondents, 55% (n = 124) were child neurology and 45% (n = 102) were adult neurology across all career stages, including students. Of the 70% who reported using social media in a professional capacity, the most commonly reported reasons were for networking and collaboration (n = 95, 60%), self-directed medical learning (n = 90, 57%), and brand building and reputation (n = 62, 39%). Twitter and Facebook were the most common and versatile platforms used by neurologists. Medical students had the highest documentation of social media scholarships on their curriculum vitae (37%, P = .016) and the most interest (33%, P = .016) in learning how to document social media scholarships if they were not already. Early faculty shared this interest more than residents, fellows, or mid-late career faculty. In all groups except for mid-late career faculty, a majority of respondents (>75%) showed interest in learning how to leverage social media for career development. Social media is used professionally by a majority of neurologists, most commonly for networking, self-directed learning, and building individual brands. Opportunities exist to better understand platform preferences and ways to optimize their use for various professional activities as well as to provide education on effective professional use of social media including documentation for promotion.
