Summary
Virtual reality (VR) simulators show promise in surgical training. Time to task completion on VR simulators correlates with surgical residents' clinical performance, particularly in gallbladder dissection tasks.
Area of Science:
- Surgical Education
- Medical Simulation
- Laparoscopic Surgery
Background:
- Assessing the efficacy of virtual reality (VR) simulators in reflecting surgical residents' clinical skills is crucial for effective training.
- Traditional surgical training methods are complemented by VR simulation for skill development.
Purpose of the Study:
- To determine if performance on a VR simulator correlates with actual clinical laparoscopic performance in surgical residents.
- To evaluate the utility of VR training in improving surgical skills.
Main Methods:
- Nine surgical residents (PGY 1-2) were assessed during laparoscopic procedures using the OpRate database over six months.
- Residents underwent iterative laparoscopic training on a VR simulator (SEP), with performance metrics including time, path length, and errors.
- Pearson correlation was used to compare VR performance data with operative performance data.
Main Results:
- A significant correlation was found between operative performance and VR scores for time to task completion in five out of six VR tasks.
- The strongest correlation was observed for a gallbladder dissection task (P = 0.0066, r = -0.6671).
- No significant correlation was found between path length or error metrics in VR tasks and operative performance.
Conclusions:
- Time to task completion on VR simulators is a valid indicator of surgical residents' performance in the operating room.
- Further serial evaluations are needed to confirm concurrent performance improvement over time with VR training.
