Background: Achieving proficiency in a surgical procedure is a milestone in the career of a trainee. We introduced a competency assessment tool for laparoscopic cholecystectomy in our residency program. Our aim was to assess the inter-rater reliability of this tool.
Methods: We included all laparoscopic cholecystectomies performed by residents under the supervision of board certified surgeons. All residents were assessed at the end of the procedure by the supervising surgeon (live reviewer) using our competency assessment tool. Video records of the same procedure were analyzed by two independent reviewers (reviewer A and B), who were blinded to the performing trainee's. The assessment had three parts: a laparoscopic cholecystectomy-specific assessment tool (LCAT), the objective structured assessment of technical skills (OSATS) and a 5-item visual analogue scale (VAS) to address the surgeon's autonomy in each part of the cholecystectomy. We compared the assessment scores of the live supervising surgeon and the video reviewers.
Results: We included 15 junior residents who performed 42 laparoscopic cholecystectomies. Scoring results from live and video reviewer were comparable except for the OSATS and VAS part. The score for OSATS by the live reviewer and reviewer B were 3.68 vs. 4.26 respectively (p = 0.04) and for VAS (5.17 vs. 4.63 respectively (p = 0.03). The same difference was found between reviewers A and B with OSATS score (3.75 vs. 4.26 respectively (p = 0.001)) and VAS (5.56 vs. 4.63 respectively; p = 0.004)).
Conclusion: Our competency assessment tool for the evaluation of surgical skills specific to laparoscopic cholecystectomy has been shown to be objective and comparable in-between raters during live procedure or on video material.
