This randomized controlled trial evaluated the impact of repeated exposure to a virtual reality (VR) anaphylaxis scenario on the performance of 125 paramedic trainees. The study found that trainees exposed to the identical scenario (VR-I) scored higher (42.6 vs 31.1 points) and performed tasks more quickly, achieving a working diagnosis and administering epinephrine faster than those with single exposure (VR-C).
Key findings
- The VR-I group scored 42.6 points compared to 31.1 points for the VR-C group.
- The VR-I group reached a working diagnosis in 1.45 minutes versus 2.90 minutes for the VR-C group.
- First IM epinephrine administration occurred at 4.58 minutes for VR-I compared to 7.43 minutes for VR-C.
Why it matters
The study highlights the potential of virtual reality as an effective training tool for paramedics, particularly in time-critical scenarios like anaphylaxis. Improved performance in simulated environments may enhance readiness for real-world emergencies.
