Leveraging immersive technology with virtual emulation for training of nonmedico combatants: A randomized controlled...

To explore the potential of virtual reality (VR) as a training tool for basic life support (BLS) and other emergency procedures to achieve higher levels of knowledge in the cognitive, psychomotor, and affective domains. Sixty trainees, divided into two groups of thirty each, were trained first using conventional methods, followed by VR devices, and then crossed over in this randomized crossover trial. Data indicators included a pre-validated set of thirty-one mixed response questions administered via Google Forms and a checklist of twelve parameters. Assessment was performed using "Direct observation of procedural skills" at four time periods, at T0 (before training), T1 (post-completion of training with the conventional or immersive technique), T2 (post-completion of training with the immersive or conventional technique), and T3 (post-three months of last training with either the conventional or immersive technique). Inferential statistics were performed using the Chi-square test for categorical variables and analysis of variance (ANOVA) for continuous variables. Intra-group comparison revealed a significant difference from T0 to T3 for all parameters in groups I and II, except for the "compression depth" parameter in group I. Inter-group comparison at T0 and T3 revealed no statistically significant difference between the two techniques. Overall satisfaction levels from T0 to T3 in both groups revealed an increasing learning preference for the VR method (46.6%-73.3% in group I and 50%-80% in group II). Immersive teaching-learning methods using VR provided a scalable and consistent learning experience, highlighting its utility for BLS training in remote or resource-constrained environments. Trainees' preferences and VR's ability to foster a desired teaching-learning environment are promising signs, warranting exploration of its long-term synergistic impact with other immersive teaching-learning methods.
