Variable Experience in Microsurgery and Flap-Based Procedures Among Canadian Plastic Surgery Residents

TITLE: Variable experience in microsurgery and flap-based procedures among Canadian plastic surgery residents. OBJECTIVE: Plastic surgery residencies are transitioning toward a competency-based education model. It is not known whether trainees can realistically achieve proficiency in microsurgical techniques during their training. This study aims to define the operative experience in the core microsurgical flap procedures among Canadian plastic surgery residents. DESIGN: Microsurgical core procedural competencies (CPCs) have been described. A retrospective review was conducted, evaluating case logs recorded by graduating plastic surgery residents at 10 Canadian English-speaking training programs between 2004 and 2014. Perceived role and competence scores were also collected and analyzed. SETTING: University of Toronto, Toronto, ON, Canada; University of British Columbia, Vancouver, BC, Canada. RESULTS: Among 27 microsurgical CPCs, 2082 procedures were logged and each resident performed an average of 37.9 (±21.7) procedures. Anterolateral thigh flaps, radial forearm-based flaps, and digit replants were the most common; however, 10.9% to 14.5% of residents did not have any operative experience with these flaps. Most residents reported zero operative experience with many of the CPCs (10.9%-100%). Co-Surgeon (50%) and First Assistant (30%) were the most common roles. None of the graduating residents reported feeling competent enough to independently perform 50% of the microsurgery CPCs. There was no difference in perceived roles when programs with ≥5 residents were compared against programs with fewer trainees. There were weak to moderate correlations between role and self-perceived competence, and between Post Graduate Year and self-perceived competence. CONCLUSIONS: There is wide variation in resident operative experience in microsurgical CPCs. Many residents graduate with little to no experience in many of the core procedures. Identifying areas of deficiency may help guide curriculum development in the new competency-based education model.
