-Summary

This study is a two-arm parallel randomized controlled non-inferiority trial designed to compare the educational effectiveness of virtual reality (VR)-based simulation with high-fidelity simulation (HFS) for emergency management training in medical interns.

Participants will be randomized 1:1 to either VR-based training or HFS-based training for managing desaturation and anaphylaxis scenarios. After training and structured debriefing, all participants will undergo objective structured clinical examinations (OSCEs) and complete pre- and post-training surveys.

The primary outcome is OSCE performance score. Secondary outcomes include confidence improvement, participant satisfaction, usability (UEQ-S).

+Arms and interventions

Arm	Type	Interventions	Description
VR Group	Experimental	Behavioral: Virtual Reality-Based Emergency Simulation	Participants use an immersive VR platform to manage simulated patients with oxygen desaturation and anaphylaxis.
HFS Group	Active comparator	Behavioral: High-Fidelity Simulation	Participants use a high-fidelity simulator (Sim-Man) to manage the same emergency scenarios.

Virtual Reality-Based Emergency Simulation (Behavioral): Participants use an immersive VR platform to manage simulated patients with oxygen desaturation and anaphylaxis.
High-Fidelity Simulation (Behavioral): Participants use a high-fidelity simulator (Sim-Man) to manage the same emergency scenarios.

+Outcome measures

Primary outcomes

OSCE Performance Score [Immediately after training]: Mean total score of two Objective Structured Clinical Examination (OSCE) stations (desaturation and anaphylaxis). Scores range from 0 to 20, with higher scores indicating better clinical performance.

Secondary outcomes

Confidence Improvement [Immediately before and immediately after training]: Self-reported confidence in emergency management measured using a 10-point Likert scale ranging from 1 to 10, with higher scores indicating greater confidence.
Participant Satisfaction [Immediately after training]: Participant satisfaction measured using a 7-point Likert scale ranging from 1 to 7, with higher scores indicating greater satisfaction.
Usability (UEQ-S) [Immediately after training]: Usability assessed using the User Experience Questionnaire-Short Version (UEQ-S). Scores range from 1 to 7, with higher scores indicating a more positive user experience.

Other outcomes

Task Completion Time [Immediately after training]: Time required to complete VR emergency scenarios, measured in seconds.
Critical Action Completion Rate [Immediately after training]: Percentage of predefined critical actions successfully completed during VR scenarios.
Task Sequence Accuracy [Immediately after training]: Accuracy of procedural task sequence during VR emergency scenarios based on predefined scenario flow.
