Background This study’s objective is to evaluate the emotional experiences, coping mechanisms, and support resources for Canadian vascular surgeons and trainees following an adverse patient event or near miss. Methods This is a cross-sectional survey study of all Canadian Society for Vascular Surgery (CSVS) members from October to November 2021. We collected data on participant experiences with adverse events, their emotional responses, the coping mechanisms used, and their perceptions on available support resources. Results The survey was sent to 233 CSVS members yielding 66 responses. The majority (77%) of respondents had experiences with adverse event causing serious patient harm. The most common negative experience following an adverse event included feelings of negativity towards oneself, general distress, and anxiety about potential for future errors. The most common coping mechanism was seeking advice from a mentor or close colleague. Peers (82%) and senior colleagues (59%) were the most preferred sources of support. Most of the respondents would reach out to a mentor if they had 1, but 30% reported no mentor or close colleague for support. Conclusion Adverse patient events and near misses have serious negative impact on the lives of Canadian vascular surgeons and trainees. Peers and senior colleagues are the most desired source for support, but this is not universally available. Organized efforts are needed to bring awareness in our vascular surgery community on the ubiquitous nature and detrimental effects of adverse events.
