 The study examines the effectiveness and practicality of virtual reality simulation, VRS, technology and training healthcare professionals for in-hospital disaster preparedness, finding that it can realistically simulate clinical environments, develop learning effects, and enable cost-effective implementation of training programs. However, the findings do not entirely cover all disaster scenarios that could happen in hospitals and recent advances in VR technologies may be necessary to enable wider adoption of VRS training on challenging clinical scenarios.
