Cognitive-skills training significantly enhances endovascular skills in inexperienced subjects using virtual reality (VR) simulators. This training is crucial for improving the quality of procedural outcomes before assessment.

Area of Science:

Medical Simulation
Endovascular Surgery
Surgical Education

Background:

Virtual reality (VR) simulation offers a potential method for objectively assessing endovascular skills.
Inexperienced subjects require effective training protocols to achieve proficiency in complex endovascular procedures.

Purpose of the Study:

To evaluate the impact of cognitive-skills training on the technical performance of novice endovascular practitioners.
To compare the performance of subjects receiving cognitive-skills training with those receiving only demonstration or experienced physicians on a VR simulator.

Main Methods:

Forty-seven surgical trainees without prior endovascular experience were divided into two groups.
Group A(1) received 45 minutes of didactic cognitive-skills training and expert demonstration with error-based learning.

Group A(2) received only a demonstration of an iliac dilation and stent procedure, followed by immediate performance on the VIST VR simulator.

Main Results:

Cognitive-skills training (Group A(1)) resulted in qualitative end-product metrics similar to experienced endovascular physicians (Group B).
Group A(1) demonstrated significantly poorer stent/vessel ratio and higher residual stenosis compared to Group B, but better than Group A(2).
While Group A(1) had longer procedure and fluoroscopy times, Group A(2) performed faster with less fluoroscopy but had significantly worse outcomes.

Conclusions:

Cognitive-skills training significantly improves the quality of the end-product in virtual reality endovascular simulation.
This type of training is fundamental for inexperienced subjects before performance assessment in VR environments.
VR simulation, enhanced by cognitive training, provides a valuable tool for surgical skill development and objective assessment.
