To identify trainee abilities associated with improved surgical performance. METHODS Twenty-five robotic surgery naïve study subjects were prospectively enrolled into an IRB approved study protocol from July-October 2012. Each subject completed the Perceptual Ability Test (PAT), a validated assessment that is part of the Dental Admission Test. Subjects were divided into two groups, with Group I comprised of the bottom 50% of PAT scores and Group II comprised of the top 50% of PAT scores. Subjects then completed 5 daVinci Skills Simulator exercises with demonstrated construct validity in differentiating novice, intermediate, and expert robotic surgeons in a previous study (Camera and Clutching Level II, Match Board Level II, Energy and Dissection Level I, Suture Sponge Level III, and Tubes). Computer generated scoring metrics for the 5 exercises were analyzed, including overall score, time to completion, economy of motion, instrument collisions, excessive instrument force, instruments out of view, and work space range. Mean overall scores and mean scores on each metric from each of the 5 exercises were compared between Groups I and II using student's t-test for independent samples. RESULTS There were 12 subjects in group I (7 male/5 female) and 13 subjects in Group II (6 male/7 female). Mean scores on the PAT were 43.0% in Group I and 67.5% in Group II (p<0.001). Mean scores on the simulator were significantly higher for Group II than Group I on 4 of the scoring metrics (time to completion, economy of motion, excessive instrument force, work space range) and showed a statistical trend toward significant superiority on the remaining 3 metrics, including overall score. (Table 1) CONCLUSIONS Group II outperformed Group I on all measured scoring metrics on the daVinci Skills Simulator, with differences in 4 out of 7 metrics achieving statistical significance. Increased spatial visualization ability as measured using the PAT correlated with better performance on the da Vinci Skills Simulator for novice robotic console users. Table 1.
