Effect of Mixed Reality on Delivery of Emergency Medical Care in a Simulated Environment: A Pilot Randomized Crossover Trial
Authors' conclusion
This study found that the use of MR technology reduced error, improved teamwork, and enhanced practitioner confidence when used to support the delivery of simulated emergency medical care.
Study context
- Population
- Resident-grade physicians in acute medical and surgical specialties, single UK Academic Health Sciences Centre, resuscitating a simulated acutely unwell patientcrossover, 2 scenarios each
- Participants
- 22 physicians
- Comparison
- Mixed-reality (MR)-supported care vs standard care in simulated emergency care
- Primary endpoint
- Error rate (Imperial College Error Capture [Imperial College Error Capture (ICECAP)] multidimensional error-capture tool)
Methodological detailspilot, single-centre, block randomized, high-fidelity simulation, September to November 2021

Mean
| Outcome | MR-SC | SC | P value |
|---|---|---|---|
| Teamwork (OTAS score) | 25.41 (SD 6.30) | 16.33 (SD 5.49) | P < 0.001 |

| NASA-TLX temporal demands | 38 (range 20–50) | 46 (range 30–70) | P = 0.03 |
| NASA-TLX self-reported task performance | 50 (range 30–60) | 39 (range 10–70) | P = 0.01 |
More confident in clinical decisions and procedures with MR support
- Participants reporting more confidence with MR support
- 19 (86.4%)
