Feasibility of a virtual reality course on adult tracheostomy safety skills*

Abstract

SummaryThe National Tracheostomy Safety Project has run high‐quality, face‐to‐face skills courses since 2009. The aim of this project was to produce a virtual reality version of the established course and evaluate its impact on participant learning, and participant and faculty satisfaction. Healthcare staff and students were recruited and randomised to attend one of (1) a face‐to‐face traditional course (control); (2) a virtual reality course at a conference centre with on‐site technical support; (3) a fully remote virtual reality course; the virtual reality groups were combined for the analysis of learning outcomes and satisfaction. The primary outcome was the difference in pre/post‐course knowledge scores on a 30‐item questionnaire; secondary outcomes included knowledge retention, usability, comfort/side effects and participant performance in a simulated tracheostomy emergency. Thirty‐seven participants and 15 faculty participated in this study. There was no significant difference between mean pre/post‐course scores from the face‐to‐face (from 21.1 to 23.1; +2) and combined virtual reality (from 17.1 to 21.1; +4) groups, with both showing improvement (p = 0.21). The mean System Usability Scale score for virtual reality was 76.8 (SD 12.6), which is above average; the median Simulator Sickness Questionnaire score was 7.5 (IQR 3.7–22.4), indicating minimal symptoms. All participants resolved the primary clinical problem in the simulated emergency, but the virtual reality (VR) group was slower overall (mean difference 61.8 s, p = 0.003). This technical feasibility study demonstrated that there was no difference in participant knowledge immediately after and 4 weeks following face‐to‐face and virtual reality courses. Virtual reality offers an immersive experience that can be delivered remotely and offers potential benefits of reducing travel and venue costs for attendees, therefore increasing the flexibility of training opportunities.
