Area of Science:

  • Surgical Education
  • Robotic Surgery
  • Virtual Reality Simulation

Background:

  • Intraoperative errors are linked to surgeon skill, which can decline with inactivity.
  • Virtual reality (VR) simulation offers a potential method to maintain and enhance surgeon technical skills.
  • Identifying optimal VR warm-up protocols is crucial for pre-operative skill priming.

Purpose of the Study:

  • To determine the most effective virtual reality (VR) warm-up curriculum for priming surgeon technical skill.
  • To validate the impact of a VR warm-up on surgeon performance in actual robot-assisted surgery.

Main Methods:

  • Surgeons participated in VR warm-up trials on the da Vinci Skills Simulator to identify optimal curricula.
  • The optimal curriculum was selected based on task completion time and technical skill assessment via video review.
  • The effect of the optimal VR warm-up was evaluated in robot-assisted surgeries using blinded performance reviews and motion metrics.

Main Results:

  • A VR warm-up curriculum focusing solely on the Running Suture task was identified as optimal, with participants being 31.3 seconds faster and scoring higher on the Global Evaluative Assessment of Robotic Skills.
  • In a subsequent trial with 34 surgeons performing 347 surgeries, the VR warm-up intervention did not lead to statistically significant differences in technical skill during the initial stages of surgery.

Conclusions:

  • A robotic virtual reality (VR) warm-up protocol, even when optimized, does not demonstrably improve surgeon technical skill in the initial phases of robot-assisted surgery.
  • Further research may be needed to explore different VR training paradigms or other methods to address skill decay in robotic surgery.
