Effectiveness of a virtual reality trainer for retention of tourniquet application skills for hemorrhage control among emergency medicine residents.

Background: With a rise in mass casualty incidents, training in hemorrhage control using tourniquets has been championed as a basic-and lifesaving-procedure for bystanders and medical professionals alike. The current standard for training is in-person (IP) courses, which can be limited based on instructor availability. Virtual reality (VR) has demonstrated the potential to improve the accuracy of certain medical tasks but has not yet been developed for hemorrhage control. The objective of this study was to evaluate the efficacy of a VR hemorrhage trainer in learner retention of tourniquet application when compared to traditional IP instructor teaching among a cohort of emergency medicine residents practicing in a Level I trauma center. Methods: This was a prospective, observational study of 53 emergency medicine residents at an inner-city program. Participants were randomly assigned to either the control or the VR group. On Day 0, all residents underwent a training session (IP vs. VR) for the proper, stepwise application of a tourniquet, as defined by the American College of Trauma Surgeons. Each participant was then assessed on the application of a tourniquet by a blinded instructor using the National Registry Hemorrhage Control Skills Lab rubric. After 3 months, each resident was reevaluated on the same rubric, with subsequent data analysis on successful tourniquet placement (measured as under 90 s) and time to completion. Results: Of the 53 participants, the IP training group had an initial pass rate of 97% (28/29) compared to 92% (22/24) in the VR group (p = 0.58). On retention testing, the IP training group had a pass rate of 95% (20/21) compared to 90% (18/20) in the VR group (p = 0.62). Stratifying the success of tourniquet placement by level of resident training did not demonstrate any statistically significant differences. Conclusions: In this pilot study of emergency medicine residents, we found no significant differences in successful hemorrhage control by tourniquet placement between those trained with VR compared to a traditional IP course among emergency medicine residents. While more studies with greater power are needed, the results suggest that VR may be a useful adjunct to traditional IP medical training.

In Situ Simulation as a Quality Improvement Tool to Identify and Mitigate Latent Safety Threats for Emergency Department SARS-CoV-2 Airway Management: A Multi-Institutional Initiative.

BACKGROUND: In situ simulation has emerged as a powerful quality improvement (QI) tool in the identification of latent safety threats (LSTs). Following the first wave of SARS-CoV-2 at an urban epicenter of the disease, a multi-institutional collaborative was formed to integrate an in situ simulation protocol across five emergency departments (EDs) for systems improvement of acute airway management. METHODS: A prospective, multi-institutional QI initiative using two Plan-Do-Study-Act (PDSA) cycles was implemented across five EDs. Each institution conducted simulations involving mannequins in acute respiratory failure requiring definitive airways. Simulations and systems-based debriefs were standardized. LSTs were collected in an online database, focused on (1) equipment availability, (2) infection control, and (3) communication. RESULTS: From June 2020 through May 2021, 58 of 70 (82.9%) planned simulations were completed across five sites with 328 unique individual participants. Overall LSTs per simulation (7.00-4.69, p < 0.001) and equipment LSTs (3.00-1.46, p < 0.001) decreased from cycle 1 to cycle 2. Changes in mean LSTs for infection control and communication categories varied among sites. There was no correlation between total LSTs or any of the categories and team size. Number of beds occupied was significantly negatively correlated with total and infection control LSTs. CONCLUSION: This study was unique in simultaneously running a structured in situ protocol across numerous diverse institutions during a global pandemic. This initiative found similar categories of threats across sites, and the protocol developed empowered participants to implement changes to mitigate identified threats.

The Comparative Effectiveness of Virtual Reality Versus E-Module on the Training of Donning and Doffing Personal Protective Equipment: A Randomized, Simulation-Based Educational Study.

Introduction Preventing errors in donning and doffing of personal protective equipment (PPE) is critical for limiting the spread of infectious diseases. Virtual reality (VR) has demonstrated itself as an effective tool for asynchronous learning, but its use in PPE training has not been tested. The objective of this study was to compare donning and doffing performance between VR and e-module PPE training. Methods A prospective randomized open-blinded controlled trial was conducted to determine differences in donning and doffing performance after VR and e-module PPE training among medical staff and medical students at a single institution. The primary outcome was donning and doffing performance with real PPE, assessed using a 64-point checklist. The secondary outcome was participant preparedness and confidence level after training.  Results Fifty-four participants were randomized, mostly consisting of medical students (n=24 {44%}) or emergency medicine and otolaryngology residents (n=19 {35%}). The VR group (n=27 {50%}) performed better than the control in the overall PPE scores but this was not statistically significant (mean {SD}, VR: 55.4 {4.4} vs e-module: 53.3 {8.1}; p = 0.40). VR participants also reported higher levels of preparedness and confidence after training. Residents as a subgroup achieved the highest increases after VR training compared to their counterparts in the control training group (mean {SD}, VR: 55.6 {4.9} vs e-module 48.4 {5.5}, p = 0.009).  Conclusion In this randomized trial, VR training was found to be non-inferior to e-module for asynchronous PPE training. Our results suggest that in particular residents may benefit most from VR PPE training. Additionally, VR participants felt more confident and prepared to don and doff PPE after training compared to e-module participants. These findings are particularly relevant given the ongoing coronavirus disease 2019 (COVID-19) pandemic. Future studies need to focus on VR integration into residency curriculum and monitoring for long-term skill retention.
