METHODS: 5 MP robotic experts (>200 cases) and 5 MP novices (<10 cases) all with no prior SP experience independently completed a validated urethrovesical anastomosis (UVA) simulation using the MP followed by the SP robot. GEARS and RACE scores were assigned by 2 blinded reviewers. Objective [galvanic skin response (GSR)] and subjective [Surg-TLX (/100) and difficulty ratings (/20) of camera movement, endowrist movement, and avoiding instrument collisions] cognitive load measurements were collected. RESULTS: Experts achieved significantly greater GEARS and RACE scores on MP (27 v 17.3, p<0.001; 26.9 v 15.9, p<0.001, respectively) and SP (24.1 v 18.1, p=0.002; 21.8 v 16.3, p=0.017) than Novices. Experts had significantly higher Surg-TLX (+13 pts, p=0.015) and difficulty ratings using SP compared to MP (+11.8, p<0.01; +13.6, p<0.01; +14 pts, p<0.01) while Novices maintained high Surg-TLX and difficulty scores on both platforms [rating only the SP camera movement to be significantly more difficult (+7.2, p=0.03)]. GSR demonstrated similar trends. Experts’ UVA performance (GEARS and RACE) significantly decreased from MP to SP (27→24.1, p=0.047; 26.9→21.8, p=0.011, respectively).On subanalysis, Experts had significant decreases in GEARS subscores of force sensitivity and robotic control (-0.7, p=0.04; -0.9, p=0.02), but maintained subscores of depth perception, bimanual dexterity, and efficiency. RACE subscores of needle entry, needle driving, and tissue approximation (-0.9, p=0.01; -1.0, p=0.02; -1.0, p<0.01) significantly decreased while maintaining subscores of needle positioning and suture placement. Both Experts and Novices were rated significantly lower at the knot tying skill on the SP robot (-1.0, p=0.03; -1.2, p=0.02, respectively). CONCLUSIONS: For experts proficient in MP, specific SP training should be developed due to partial skill transference. Cognitive load remained steady for novices across robots, suggesting that concurrent SP and MP training may be possible.
