The personality traits commonly seen in abdominal surgeons remains undefined, and its potential influence on decision-making and patient outcomes underexplored. This systematic review identified studies on abdominal surgeons who had undergone validated personality testing, with assessment of decision-making and post-operative patient outcomes. The study protocol was registered on PROSPERO (University of York, UK (CRD42019151375)). MEDLINE, Embase, PsycInfo and Cochrane Library databases were searched using the keywords: surgeon; surgeon personality; outcomes. All study designs were accepted including adult visceral surgeons published in English. Five articles from 3056 abstracts met our inclusion criteria and one article was identified from hand searches with two reviewers screening studies. Bias was assessed using the Newcastle-Ottawa scale. Six studies included 386 surgeons. Studies assessing personality using the Five Factor Model (four studies, 329 surgeons) demonstrated higher levels of conscientiousness (self-discipline, thoughtfulness), extraversion (sociability, emotional expression) and openness (creative, conventional) in surgeons versus population norms. Surgeon characterisation of agreeableness and emotional stability was less clear, with studies reporting mixed results. Post-operative outcomes were reported by only one study. Further exploration of the influence of surgeon personality and its influence on decision-making is necessary to deliver patient-centred care and targeted non-technical skills training for surgeons.
