Virtual reality suturing task as an objective test for robotic experience assessment

摘要

Background We performed a pilot study using a single virtual-simulation suturing module as an objective measurement to determine functional use of the robotic system. This study will assist in designing a study for an objective, adjunctive test for use by a surgical proctor. Methods After IRB approval, subjects were recruited at a robotic renal surgery course to perform two attempts of the “Tubes” module without warm-up using the Da Vinci? Surgical Skills Simulator?. The overall MScore (%) from the simulator was compared among various skill levels to provide construct validity. Correlation with MScore and number of robotic cases was performed and pre-determined skill groups were tested. Nine metrics that make up the overall score were also tested via paired t test and subsequent logistic regression to determine which skills differed among experienced and novice robotic surgeons. Results We enrolled 38 subjects with experience ranging from 0-?2 =?0.465; p?=?0.003). MScore was different between novice and more experienced robotic surgeons on the first (44.7 vs. 63.9; p?=?0.005) and second attempt (56.0 vs. 69.9; p?=?0.037). Conclusion A single virtual simulator exercise can provide objective information in determining proficient use of the robotic surgical system.
