Gastrointestinal endoscopy·2026

This study found the CAE EndoscopyVR Simulator has poor validity for predicting real-world endoscopy skills. Trainee performance differences were minimal, and simulations were deemed unrealistic.

Area of Science:

  • Medical Simulation
  • Gastroenterology Training
  • Surgical Skills Assessment

Background:

  • Computer-based simulators offer potential for endoscopy skill acquisition before patient procedures.
  • Validation of these simulators is crucial for their effective use in training and assessment.

Purpose of the Study:

  • To assess the content and criterion validity of the CAE EndoscopyVR Simulator's colonoscopy and EGD modules.
  • To determine if the simulator can predict clinical endoscopic skills.

Main Methods:

  • A prospective, observational study at a single academic center.
  • Involved 5 novice fellows and 6 expert physicians performing simulated colonoscopies and EGDs.
  • Compared 57 objective performance parameters and analyzed survey feedback.

Published on: May 6, 2020

Main Results:

  • Only 33% of performance metrics showed significant differences between novices and experts.
  • Most significant differences were time-related; few non-time related differences were of uncertain clinical significance.
  • Survey data indicated aspects of the simulation were unrealistic compared to live endoscopy.

Conclusions:

  • The CAE EndoscopyVR Simulator demonstrates poor content and criterion validity.
  • The simulator is currently incapable of predicting in vivo endoscopic skill proficiency.
