Comparison of faculty versus structured peer-feedback for acquisitions of basic and intermediate-level surgical skills

Abstract

PurposeVideo feedback and faculty feedback has been shown to improve surgical performance; however, consistent access to faculty is challenging. We studied the utility of structured peer-feedback (PF) compared to faculty-feedback (FF) during acquisition of basic and intermediate surgical skills. MethodologyTwo randomized non-inferiority trials were conducted with 1st (n = 30) and 2nd year (n = 29) medical students learning skin-lesion excision and closure (S), and single-layer hand-sewn bowel anastomosis (B), respectively. Five attempts were performed. PF participants used an Objective Structured Assessment of Technical Skills tool to guide feedback. Blinded raters assessed video-recorded performance, time and Integrity of the completed task were also assessed. ResultsFor both tasks performance by PF was comparable to FF (P = 0.111). Both groups improved significantly: performance (B:P < 0.0001, S:P = 0.035), time (B:P = 0.043, S:P < 0.0001) and integrity (B:P < 0.0001, S:P < 0.032). ConclusionStructured peer-feedback is equivalent to faculty-feedback in the acquisition of basic and intermediate surgical skills, giving students freedom to practice independently.
