Proficiency Maintenance: Impact of Ongoing Simulator Training on Laparoscopic Skill Retention

BACKGROUND: Proficiency-based training in laparoscopic suturing and knot tying translates to the operating room, but little is known about the durability of acquired skill. The purpose of this study was to determine the effect of maintenance training on skill retention after demonstration of proficiency. STUDY DESIGN: Medical students (n! 18) with no previous laparoscopic or simulator experience were enrolled in an IRB-approved randomized controlled trial. All subjects trained to proficiency (score of 512, based on time and errors) on a previously validated suturing model (Fundamentals of Laparoscopic Surgery videotrainer). Subjects were then randomized to a control group, which received no additional training, and an ongoing training group, which trained again to profi-ciency at 1 and 3months (immediately after testing). Simulator testing was repeated at 2 weeks, 1 month, 3 months, and 6 months after initial training. No subject had interval operative experience. RESULTS: Both groups demonstrated excellent skill retention during followup; performance scores, re
