Laparoscopic simulation training with proficiency _targets improves practice and performance of novice surgeons

Paul G Gauger et al. Am J Surg. 2010 Jan.

Abstract

Background: This study compares a laparoscopic skill training protocol without proficiency _targets to the same protocol with explicit _targets and notification of progress.

Methods: Fourteen surgery interns were randomized into 2 groups. The intervention group received task-specific proficiency criteria to guide practice. The control group did not. After training, participants were evaluated by blinded faculty during laparoscopic cholecystectomy.

Results: The control group met significantly fewer of the 7 LapSim (Surgical Science Sweden AB, Gotëborg) _targets (mean = 1.14) than the intervention group (mean = 7.00; P = .001) and significantly fewer of the 5 video trainer _targets (mean = .86) than the intervention group (mean = 5.00; P = .001). Ratings of depth perception, bimanual dexterity, efficiency, tissue handling, autonomy, and overall competence were higher for the intervention group. Effect sizes ranged from medium to large (.394-.981), indicating an impact of the proficiency-based training protocol.

Conclusions: Delineation of proficiency _targets with reporting of progress improves interns' practice results, and appears to have a positive effect on their early operating room (OR) performance of laparoscopic cholecystectomy.
