Conclusions
MR
This randomized crossover trial found that wearable MR technology improved technical performance and reduced error in clinicians performing complex tasks in high-intensity simulated environments. Use of MR most notably impacted the ability to complete complex procedural tasks, such as intercostal drain insertion for novice trainees. While MR is in its infancy, our findings suggest promise for the technology in improving the quality of care, enhancing access to specialist care in remote settings, and supporting junior medical staff to be more confident in delivering high-quality care. Not all advances that show benefits in simulated environments translate to clinical settings, so the potential benefits of this technology must now be investigated in live clinical settings in order to demonstrate its safety, effectiveness, and scalability.
