Past surveys demonstrated that a significant number of patients thought that social media content would affect their choice of physician, hospital, or medical facility. Our goal was to evaluate the extent of unprofessional social media content among recent vascular surgery fellows and residents. The Association of Program Directors in Vascular Surgery directory was used to compile a list of the vascular trainees from 2016 to 2018. Neutral Facebook, Twitter, and Instagram accounts were searched for public information. All content was screened by two separate investigators for predetermined material categorized as either unprofessional or potentially objectionable. Unprofessional content included Health Insurance Portability and Accountability Act violations, appearing intoxicated, unlawful behavior, possession of drugs or drug paraphernalia, and uncensored profanity or offensive comments about colleagues and work or patients. Potentially objectionable content included holding or consuming alcohol, inappropriate attire, censored profanity, controversial political or religious comments, and controversial social topics. Evaluation of 480 vascular trainees revealed that 325 (68%) were male, 456 (95%) held MD degrees, and 115 (24%) were integrated 0 + 5 residents; 61 (30%) account holders had either unprofessional or potentially objectionable content, with 8 (3.4%) containing content categorized as unprofessional. The only forms of unprofessional content identified were obvious alcohol intoxication in three Facebook accounts and uncensored profanity or offensive comments about colleagues and work or patients in one Facebook and five Twitter accounts. Potentially objectionable content included holding or consuming alcohol (12.3%), controversial political comments (9.4%), inappropriate or offensive attire (3.8%), censored profanity (3.4%), controversial social topics (2.5%), and controversial religious comments (0.9%). There was no significant difference in objectionable content between sex, training (MD vs non-MD), or track (0 + 5 or 5 + 2; all P > .05). However, there was more unprofessional or potentially objectionable content for those who self-identified as vascular surgeons (33% vs 17%; P = .007). Half of recent and current vascular trainees had an identifiable social media account, with nearly a third of these containing unprofessional or potentially objectionable content. Account holders who self-identified as vascular surgeons were more likely to be associated with objectionable social media behavior. Young surgeons should be aware of the permanent public exposure of potentially objectionable content that can be accessed by peers, patients, and current or future employers.
