When Seconds Count: Designing Real-Time VR Interventions for Stress Inoculation Training in Novice Physicians

2026-01-24

AI Summary

This study addresses the vulnerability of novice physicians to acute cognitive overload during surgical emergencies, which impairs their decision-making capabilities, and the lack of real-time support in existing virtual reality (VR)-based stress inoculation training (SIT) systems. Based on needs assessments with 12 novice doctors, the authors propose three intervention strategies—self-regulated assistance, procedural guidance, and affective/sensory support—and present the first real-time adaptive VR-SIT system that dynamically tailors support according to learners’ ongoing cognitive and emotional states. Integrating VR with physiological and behavioral sensing technologies, the system enables precise, context-aware responses under high-stress conditions. A user study with 26 participants validated the effectiveness of the proposed strategies, offering empirical evidence and a design framework for next-generation intelligent VR-based medical training systems.

Abstract

Surgical emergencies often trigger acute cognitive overload in novice physicians, impairing their decision-making under pressure. Although Virtual Reality-based Stress Inoculation Training (VR-SIT) shows promise, current systems fall short in delivering real-time, effective support during moments of peak stress. To bridge this gap, we first conducted a formative study (N=12) to uncover the core needs of novice physicians for immediate assistance under acute stress and identified three key intervention strategies: self-regulation aids, procedure guidance, and emotional/sensory support. Building on these insights, we designed and implemented a novel VR-SIT system that incorporates a just-in-time adaptive intervention framework, dynamically tailoring support to learners'cognitive and emotional states. We then validated these strategies in a user study (N=26). Our findings provide empirical evidence and design implications for next-generation VR medical training systems, supporting physicians in sustaining cognitive clarity and accurate decision-making in critical situations.
