Laparoscopy and Roboticsda Vinci Skills Simulator Construct Validation Study: Correlation of Prior Robotic Experience With Overall Score and Time Score Simulator Performance
Section snippets
Material and Methods
Thirty-nine robotic surgeons completed 24 consecutive exercises on the robotic simulator; each exercise was completed only once and no surgeon had prior experience on the da Vinci Skills Simulator. Participants included general surgeons (11), gynecologists (16), and urologists (12). Twenty-seven were practicing surgeons, 3 were fellows, and 9 were residents (2-PGY II, 4-PGY III, 3-PGY IV). This study was completed at one academic institution and the participants came from both academic and
Results
The overall scores were 64.7% (standard error [SE] 13.4) for group I, 79.1% (SE 5.5) for group II, and 87.4% (SE 3.9) for group III. Between the 3 groups, the overall scores were both statistically significant (P <.001) and demonstrated a significant linear relationship (P <.001). Total time scores were 39.1% (SE 17.7) for group I, 58.6% (SE 21.2) for group II, and 87.3% (SE 8.6) for group III and were also both statistically significant (P <.001) and demonstrated a significant linear
Comment
Compared with prior published studies, this study had a high number of participants of varying prior experience and each participant performed all the simulator exercises,24 providing a comprehensive picture of robotic simulator performance. The complete 24-exercise set took surgeons between 1.5 and 4 hours to complete and used 12 performance metrics. There was a significant linear relationship between the 3 groups of robotic surgeons: group I, group II, and group III, in the analysis of both
Conclusions
Initial construct validity analysis of the da Vinci Skills Simulator revealed that increased simulator performance, as measured by overall scores and time scores correlated with surgeons who reported a greater number of prior robotic procedures. Simulation training has the potential to increase psychomotor skills and platform familiarity before there is patient contact. Future studies are needed to determine whether the use of simulation technology increases robotic proficiency of both

The most obvious advantage of the DVSS is that the simulator and console are one and the same, but it is also the most well-validated: By virtue of using the same software, the validation studies for the dV-Trainer can be extrapolated to the DVSS, and additional studies have further supported the face, content, construct, concurrent, and predictive validity of the DVSS specifically.27–31 The DVSS is officially supported by Intuitive in its Da Vinci Residency and Fellowship Training Program Implementation Guide.32
