An interventional study of Virtual Reality-Based Emergency Simulation and High-Fidelity Simulation in Anaphylaxis and Hypoxia, sponsored by Seoul National University Hospital. Active, not recruiting at 1 site in South Korea. Per ClinicalTrials.gov, last updated 2026-05-13.
Sponsored by Seoul National University Hospital · Not applicable, Interventional, and Other
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).
100 studies on the registry are indexed under Anaphylaxis; 20 are open to participants now.
This study's planned enrollment of 124 is above the median of 40 across 50 interventional studies indexed under Anaphylaxis.

Exclusion Criteria
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

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

OSCE Performance Score
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.
Time frame: Immediately after training
Confidence Improvement
Self-reported confidence in emergency management measured using a 10-point Likert scale ranging from 1 to 10, with higher scores indicating greater confidence.
Time frame: Immediately before and immediately after training
Participant Satisfaction
Participant satisfaction measured using a 7-point Likert scale ranging from 1 to 7, with higher scores indicating greater satisfaction.
Time frame: Immediately after training
Usability (UEQ-S)
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.
Time frame: Immediately after training
Task Completion Time
Time required to complete VR emergency scenarios, measured in seconds.
Time frame: Immediately after training
Critical Action Completion Rate
Percentage of predefined critical actions successfully completed during VR scenarios.
Time frame: Immediately after training
Task Sequence Accuracy
Accuracy of procedural task sequence during VR emergency scenarios based on predefined scenario flow.
Time frame: Immediately after training
