Self-Assessment of Surgical Skills: A Systematic Review.

OBJECTIVE: Self-assessment is fundamental in surgical training to enhance learning in the absence of trainer feedback. The primary objective of this review was to assess the factors that influence accuracy of self-assessment at technical skills across all surgical specialties. The secondary objective was to assess whether there are any innate factors or attributes to predict those that will carry out effective self-assessment. DESIGN: A systematic review was carried out in accordance with PRISMA guidelines. A search strategy encompassing MEDLINE, EMBASE, ERIC, WHO, and the Cochrane database was conducted to identify studies investigating self-assessment at any surgical task. Quality was assessed using the Newcastle-Ottawa scale. A summary table was created to describe specialty, participants, task, setting, assessment tool, and correlation coefficient between self and expert assessment. The review protocol was registered in PROSPERO. RESULTS: Of 24,638 citations, 40 met inclusion criteria. In total 1753 participants performed 68 procedures. Twenty-six studies investigated skills in general surgery with the remaining 14 in various other surgical specialties. Accuracy of self-assessment is superior in those with greater experience and age, and with use of retrospective video playback. Accuracy tends to be reflected by overestimation of performance. Stressful environments reduce accuracy. There is limited evidence in the literature regarding predicting traits for those who will carry out accurate self-assessment. CONCLUSIONS: The ability to perform accurate self-assessment is an important skill in surgical training, with accuracy being influenced by a multitude of factors. The use of self-assessment from retrospective video playback may be of benefit in surgical training curricula to enhance learning of technical skills. Further studies are required to define predictors of good self-assessment, which will strengthen recruitment and mentoring to assist trainee learning.
