A physical surgical simulator, the McGill Inanimate System for Training and Evaluation of Laparoscopic Skills (MISTELS) is used to examine the acquisition of laparoscopic skills, as well as to determine a summative evaluation of these skills. The cumulative summation method (CUSUM) is used to characterize individual and group learning curves for a MISTELS task. To examine transfer of learning in laparoscopy, novice laparoscopists were randomized to either practice a basic psychomotor task (peg board transfer) or to a no-practice control group. After forty iterations, the novices performed a more complex task (suturing); those who practiced the basic task significantly improved their complex task performance. Finally, using the receiver operator curve (ROC), the summative evaluation score for MISTELS was determined by maximizing the sensitivity and specificity of this training instrument. Using these findings, individualized training programs can be developed to teach essential laparoscopic skills prior to entering the operating room.
