Robotic surgical simulator performance did not correlate with the real-life surgical skills of attending surgeons. New simulation exercises are needed to improve novice robotic surgeon training and performance.

Area of Science:

Surgical Education
Robotic Surgery
Medical Simulation

Background:

Expert review of surgical videos can assess laparoscopic skill and predict outcomes.
Robotic surgery simulation is increasingly used for training surgeons.

Purpose of the Study:

To evaluate the correlation between robotic surgical simulation performance and the real-life surgical skill of attending surgeons.
To test the hypothesis that simulation performance does not correlate with real-life robotic surgical skill.

Main Methods:

Ten attending robotic surgeons completed four tasks on the da Vinci Skills Simulator.
Video clips of robotic-assisted operations were recorded for each surgeon.
Three expert robotic surgeons rated the intraoperative videos using the Global Evaluative Assessment of Robotic Skills (GEARS).

Keywords:

Patient Care Practice-Based Learning and Improvement clinical competence in medical education education robotics simulation center surgery training

Published on: August 15, 2025

Main Results:

No significant correlation was found between individual simulator task scores and expert video ratings.
The overall simulation score showed no correlation with expert ratings of intraoperative performance (r = -0.0304).
Surgeons had a median of 7.25 years of experience and 91 cases in the past 4 years.

Conclusions:

Robotic surgical simulator performance does not correlate with attending surgeons' real-life robotic surgical skill.
Current robotic simulators may not effectively translate to improved intraoperative performance for experienced surgeons.
Development of advanced simulation exercises is necessary to guide novice surgeons toward expert performance.
