The aim of this study was to assess skill retention in the operating room following completion of a proficiency-based laparoscopic skills curriculum. Novices (n = 15) were randomized to a control and a training group that practiced to proficiency on the Fundamentals of Laparoscopic Surgery suturing model. The performance of both groups was assessed on the simulator and on a live porcine laparoscopic Nissen fundoplication model at training completion (posttest) and 5 months later (retention test). Training to proficiency required 4.7 ±1.2 hours and 41 ± 10 repetitions. Trained participants outperformed controls, and their performance deteriorated slightly between posttests and retention tests on the simulator (505 ± 22 vs 462 ± 50, respectively; P < .05) but not in operating room (263 ± 138 vs 279 ± 88, respectively; P = .38). Proficiency-based simulator training results in durable improvement in operative skill of trainees even in the absence of practice for up to 5 months. Minute simulator performance changes do not translate to the operating room.

Key Words: simulator training • skill retention • laparoscopic suturing • skill • transfer
