In order to determine the value of virtual reality robotic simulation and its objective metrics, a reality-based robotic surgical training platform with similar analytic capabilities must be developed and validated. The ProMIS laparoscopic surgical simulator is a widely available and extensively studied simulation platform that has been previously validated as an objective measure of laparoscopic task performance. In this study, we evaluated the validity of the ProMIS laparoscopic surgical simulator as an objective measure of robotic task performance. METHODS Volunteers were recruited from two experience groups (novice and expert). After a standardized orientation and practice session, all subjects completed three tasks (peg transfer, precision cutting, intracorporeal suture/knot) in the ProMIS laparoscopic simulator using the daVinci robotic surgical system. Motion analysis data was obtained by the ProMIS computerized optical tracking system and objective metrics recorded included time, path length, economy of motion, and observer-recorded penalty scores. An independent sample t-test was used to compare these metrics. After task completion, all subjects completed questionnaires rating parameters of face and content validity on a five-point Likert scale. RESULTS The novice group consisted of 10 subjects with no previous robotic surgical experience. The expert group consisted of 8 subjects with significant robotic experience. The expert group outperformed the novice group to statistical significance in all three tasks. Subjects rated this training platform as easy to use, as an accurate measure of their robotic surgical proficiency, and as relevant to robotic surgical training. The experts described the simulator platform as useful for training and agreed with incorporating it into a robotic surgery training curriculum. CONCLUSIONS Our data indicates that the ProMIS laparoscopic simulator is a face, content, and construct valid simulation platform that can be used to objectively measure robotic task performance.
