The utility of virtual reality and manikin crisis scenario simulations for anaesthesia trainee education: a randomised crossover pilot study

Simulation education for anaesthesia trainees is essential to build clinical skills and virtual reality can provide a reproducible, high-fidelity intra-operative training environment. Compared to in-situ manikin-based simulation, this modality has yet to be thoroughly evaluated. Twenty-six second post-graduate year anaesthesiology residents were randomly divided into two groups and participated in both virtual reality and manikin crisis scenarios at sessions six months apart. The exposure order was group A virtual reality followed by manikin and group B manikin followed by virtual reality. Clinical assessments were performed using a standardised checklist. Knowledge assessments were conducted. National Aeronautics and Space Administration Task Load Index and System Usability Scale scores were collected immediately after participation. Clinical scores between groups A and B were not significantly different. Group A had improved post-simulation knowledge scores after both sessions. Task load index scores were lower in mental demand for virtual reality. System usability scores showed less ease of use and more need for support in virtual reality.
