Training for mass casualty incident (MCI) response is critical to ensure that resource allocation and treatment priorities limit preventable mortality. Previous research has investigated the use of immersive virtual environments as an alternative to high fidelity MCI training, which is expensive and logistically challenging to implement. While these have demonstrated positive early results, they still require complex technology deployment, dedicated training facilities, and significant time from instructors and facilitators. This study explores the feasibility of a smartphone-based application for trauma care training and MCI triage to fill the gap between classroom learning and high-fidelity simulation. The goals of this investigation were to evaluate clinician perceptions of a virtual MCI training simulator's usability, acceptability, fidelity, functionality, and pacing.
This study used a smartphone-based training simulation called Extensible Field and Evacuation Care Training in a Virtual Environment (EFECTIVE), which presents virtual patient scenarios in a gamified, but visually high-fidelity environment. A total of 21 participants were recruited as a convenience sample of medical students, paramedics, nurses, and emergency medicine resident and attending physicians at University of Massachusetts Memorial Medical Center, an urban tertiary care medical center. Participants completed a brief tutorial and then performed a series of virtual patient scenarios and 1 MCI scenario on the simulator, each of which was 5 minutes in duration. Then, each participant completed a survey assessing the perceived usability, acceptability, fidelity, functionality, and pacing of the virtual training simulator. The research protocol was approved by the University of Massachusetts Chan Medical School Institutional Review Board.
48% of participants disagreed that a virtual simulator could completely replace live MCI training, though 71% agreed that app-based simulations could effectively supplement live MCI training and 67% felt that they could be used to learn how to order medical interventions in care under fire scenarios. 80% of participants agreed that the simulation could be used to practice MCI triage and to gain experience with coordinating movement of casualties to casualty collection points. 67% of participants believed that use of virtual simulators would increase their MCI preparedness. 76% agreed that the clinical cases depicted were medically realistic and that the clinical cases presented accurately represented the scenarios described. In addition, despite being presented on a smartphone as opposed to virtual reality, 62% of participants rated the experience immersive.
This study provides encouraging evidence that easy to deploy smartphone-based simulations may be an effective way to supplement MCI and care under fire training. Although the study is limited by a small sample size, there was strong agreement among participants from a wide variety of emergency medicine roles that such a simulation could train core topics associated with MCI triage. Because app-based simulations are easily deployable and can be executed quickly and frequently, they could be used as a more flexible training model compared to large scale live or virtual reality-based simulations. The results of this investigation also indicate that a sufficient level of medical realism can be achieved without live simulation.
大规模伤亡事件(MCI)应对培训对于确保资源分配和治疗优先级以限制可预防的死亡率至关重要。先前的研究已经调查了使用沉浸式虚拟环境作为高保真 MCI 培训的替代方法,这种方法昂贵且在实施方面具有挑战性。虽然这些方法已经取得了积极的早期成果,但它们仍然需要复杂的技术部署、专用的培训设施以及来自讲师和导师的大量时间。本研究探讨了基于智能手机的应用程序在创伤护理培训和 MCI 分诊中的可行性,以填补课堂学习与高保真模拟之间的空白。本研究的目的是评估临床医生对虚拟 MCI 培训模拟器的可用性、可接受性、逼真度、功能和节奏的看法。
这项研究使用了一种基于智能手机的培训模拟软件,称为可扩展现场和虚拟环境中的疏散护理培训(EFECTIVE),它在游戏化但视觉上高保真的环境中呈现虚拟患者场景。共有 21 名参与者作为马萨诸塞大学纪念医疗中心的医学生、护理人员、护士以及急诊住院医师和主治医生的便利样本被招募。参与者完成了一个简短的教程,然后在模拟器上完成了一系列虚拟患者场景和 1 个 MCI 场景,每个场景持续 5 分钟。然后,每位参与者完成了一项调查,评估他们对虚拟培训模拟器的感知可用性、可接受性、逼真度、功能和节奏的看法。该研究方案获得了马萨诸塞大学陈医学院机构审查委员会的批准。
48%的参与者不同意虚拟模拟器可以完全替代现场 MCI 培训,尽管 71%的参与者同意基于应用程序的模拟可以有效地补充现场 MCI 培训,67%的参与者认为他们可以用于学习在火力下的医疗干预措施的顺序。80%的参与者同意该模拟可用于练习 MCI 分诊,并获得在伤员收集点协调伤员转移的经验。67%的参与者认为使用虚拟模拟器可以提高他们的 MCI 准备情况。76%的参与者同意所呈现的临床病例在医学上是现实的,并且呈现的临床病例准确地代表了描述的场景。此外,尽管是在智能手机上呈现,而不是虚拟现实,62%的参与者认为体验具有沉浸感。
这项研究提供了令人鼓舞的证据,表明易于部署的基于智能手机的模拟可能是补充 MCI 和火力下护理培训的有效方法。尽管该研究受到小样本量的限制,但来自各种急诊医学角色的参与者强烈同意,这样的模拟可以培训与 MCI 分诊相关的核心主题。由于基于应用程序的模拟易于部署并且可以快速频繁地执行,因此与大规模现场或虚拟现实模拟相比,它们可以作为更灵活的培训模型。这项研究的结果还表明,即使没有现场模拟,也可以达到足够的医学真实感水平。
