Development of virtual reality content for learning Japan Prehospital Trauma Evaluation and Care initial assessment procedures.

Aim: The Japan Prehospital Trauma Evaluation and Care (JPTEC) is a standardized educational program for prehospital trauma care in Japan. The initial assessment in the JPTEC course comprises a training segment that includes a 30-min session. Given the limited face-to-face training due to the coronavirus disease 2019, virtual reality (VR) content has become an alternative. However, creating VR content typically requires the assistance of expert technicians. We aimed to create VR content for the initial assessment segment of the JPTEC and verify its educational effectiveness.

Methods: We created VR content for learning the initial assessment of the JPTEC using our easy-to-use VR content creation system. The participants played the VR content for 15 min. The number of times they "cleared" (i.e., made a correct decision and completed the initial assessment) was recorded every 5 min. Then, a JPTEC-certified instructor tested their practical skills through face-to-face simulation.

Results: The authors had no specialized skills and created the VR content in 2 days. Fourteen students used the material. They cleared the scenario 3 (3-4) times in the first 5 min in 15 min, 5 (4-5) times in the second 5 min, and 5 (5-5) times in the third 5 min ( < 0.05). All participants passed the practical evaluation.

Conclusion: A shorter VR training developed using our easy-to-use VR content creation system can replace the 30-min JPTEC session on the initial assessment. This system allows for the free and easy creation of VR content.
