Pdf Summary

A study conducted by Laura K. Newcomb et al. aimed to determine the correlation between virtual reality (VR) surgical simulation drills and validated robotic objective structured assessment of technical skills (R-OSATS) dry lab drills. The study involved 30 participants from various surgical departments who completed five VR drills and five dry lab drills. The VR drills were scored automatically by the simulator while the dry lab drills were recorded and scored by three blinded experts using the R-OSATS assessment tool.<br /><br />The results showed a strong correlation (r=0.87) between overall summary scores of the VR and dry lab drills. Each of the five VR drills also had a statistically significant correlation to its corresponding dry lab drill, with correlation coefficients ranging from 0.49 to 0.73. The performance on VR drills also confirmed construct validity, as faculty and fellows consistently had higher scores than residents.<br /><br />The study found that a core set of VR drills reliably correlated with validated dry lab R-OSATS drills. This suggests that VR drills could serve as an ancillary method of determining trainee competency, providing a more flexible and autonomous method of training compared to the time-consuming and effort-intensive dry lab drills.<br /><br />Overall, the study concluded that the selected VR drills could be used as a reliable ancillary method of simulation assessment and could potentially be used to transition resident certification from dry lab drills to VR drills. This would provide a more accessible and objective method of assessing trainees' surgical skills. However, it should be noted that the findings for the Vertical Defect Suturing drill may not be generalizable due to limited availability on all simulators and the lack of standardized scoring for this particular drill.
