Designing Virtual Reality–Based Conversational Agents to Train Clinicians in Verbal De-escalation Skills: Exploratory Usability Study (Preprint)
Publisher: JMIR Publications Inc.
Date: 12-04-2022
Abstract: iolence and aggression are significant workplace challenges faced by clinicians worldwide. Traditional methods of training consist of “on-the-job learning” and role-play simulations. Although both approaches can result in improved skill levels, they are not without limitation. Interactive simulations using virtual reality (VR) can complement traditional training processes as a cost-effective, engaging, easily accessible, and flexible training tool. n this exploratory study, we aimed to determine the feasibility of and barriers to verbal engagement with a virtual agent in the context of the Code Black VR application. Code Black VR is a new interactive VR-based verbal de-escalation trainer that we developed based on the Clinical Training Through VR Design Framework. n total, 28 participants with varying clinical expertise from 4 local hospitals enrolled in the Western Sydney Local Health District Clinical Initiative Nurse program and Transition to Emergency Nursing Programs and participated in 1 of 5 workshops. They completed multiple playthroughs of the Code Black VR verbal de-escalation trainer application and verbally interacted with a virtual agent. We documented observations and poststudy reflection notes. After the playthroughs, the users completed the System Usability Scale and provided written comments on their experience. A thematic analysis was conducted on the results. Data were also obtained through the application itself, which also recorded the total interactions and successfully completed interactions. he Code Black VR verbal de-escalation training application was well received. The findings reinforced the factors in the existing design framework and identified 3 new factors—motion sickness, perceived value, and privacy—to be considered for future application development. erbal interaction with a virtual agent is feasible for training staff in verbal de-escalation skills. It is an effective medium to supplement clinician training in verbal de-escalation skills. We provide broader design considerations to guide further developments in this area.

Randomised controlled trial of simulation-based education for mechanical cardiopulmonary resuscitation training
Publisher: BMJ

DOI: 10.1136/EMERMED-2017-207431
Abstract: Mechanical cardiopulmonary resuscitation (M-CPR) is increasingly used in the management of cardiac arrest. There are no previously reported randomised studies investigating M-CPR training. This study of newly trained M-CPR providers hypothesised that a brief simulation-based intervention after 4 months would improve M-CPR performance at 6 months. This study used a simulated ‘in situ’ cardiac arrest model. The M-CPR device used was a proprietary Lund University Cardiac Assist System 3 machine (Physio Control, Redmond, Washington, USA). Standardised baseline training was provided to all participants. Following training, baseline performance was assessed. The primary outcome measure was the time taken to initiate M-CPR and the secondary outcome was performance against a checklist of errors. Participants were then randomised to intervention group (simulation training) or control group (routine clinical use of M-CPR). After 6 months the outcome measures were reassessed. Comparative statistical tests used an intention-to-treat analysis. 112 participants were enrolled. The intervention group (n=60) and control group (n=52) had similar demographic characteristics. At the 6-month assessment, median time to M-CPR initiation was 27.0 s (IQR 22.0–31.0) in the intervention group and 31.0 s (IQR 25.6–46.0) in the control group (p=0.003). The intervention group demonstrated fewer errors compared with controls at 6 months (p .001) In this randomised study of approaches to M-CPR training, providers receiving additional simulation-based training had higher retention levels of M-CPR skills. Therefore, when resuscitation skills are newly learnt, provision follow-up training should be an important consideration.
Exploring User Needs in the Development of a Virtual Reality–Based Advanced Life Support Training Platform: Exploratory Usability Study (Preprint)
Publisher: JMIR Publications Inc.

Abstract: raditional methods of delivering Advanced Life Support (ALS) training and reaccreditation are resource-intensive and costly. Interactive simulations and gameplay using virtual reality (VR) technology can complement traditional training processes as a cost-effective, engaging, and flexible training tool. his exploratory study aimed to determine the specific user needs of clinicians engaging with a new interactive VR ALS simulation (ALS-SimVR) application to inform the ongoing development of such training platforms. emistructured interviews were conducted with experienced clinicians (n=10, median age=40.9 years) following a single playthrough of the application. All clinicians have been directly involved in the delivery of ALS training in both clinical and educational settings (median years of ALS experience=12.4 all had minimal or no VR experience). Interviews were supplemented with an assessment of usability (using heuristic evaluation) and presence. he ALS-SimVR training app was well received. Thematic analysis of the interviews revealed five main areas of user needs that can inform future design efforts for creating engaging VR training apps: affordances, agency, erse input modalities, mental models, and advanced roles. his study was conducted to identify the needs of clinicians engaging with ALS-SimVR. However, our findings revealed broader design considerations that will be crucial in guiding future work in this area. Although aligning the training scenarios with accepted teaching algorithms is important, our findings reveal that improving user experience and engagement requires careful attention to technology-specific issues such as input modalities.

A prospective evaluation of the ‘C.O.A.C.H.E.D.’ cognitive aid for emergency defibrillation
Publisher: Elsevier BV

DOI: 10.1016/J.AUEC.2018.08.002
Abstract: International guidelines recommend that interruptions to chest compressions are minimised during defibrillation. As a result, some resuscitation educators have adopted a more structured approach to defibrillation. One such approach is the 'C.O.A.C.H.E.D.' cognitive aid (Continue compressions, Oxygen away, All others away, Charging, Hands off, Evaluate, Defibrillate or Disarm). To date, there are no studies assessing the use of this cognitive aid. This study utilised an Emergency Department in situ simulated model of cardiac arrest. The defibrillator used was a proprietary R-Series (Zoll, PA, USA) connected to a CS1201 rhythm generator (Symbio, Beaverton, OR, USA). The study cohorts were interdisciplinary advanced life support (ALS) providers. Paired providers were enrolled in a mechanical CPR (M-CPR) training programme with no feedback related to defibrillation performance. As part of this 6-month programme, serial defibrillation performance was assessed. The outcome measures were the length of 'peri-shock' pause and 'safety' of defibrillation practice. Comparative statistical analysis using the Mann-Whitney U-test was made between groups of providers with 'correct use or near correct' or 'entirely incorrect or absent' use of the cognitive aid. The C.O.A.C.H.E.D. cognitive aid was applied correctly in 92 of 109 defibrillations. Providers with correct cognitive aid use had a median length of peri-shock pause time of 6.0s (IQR 5.0-7.0). Providers with 'entirely incorrect or absent' cognitive aid use had a peri-shock pause time of 8.0s (IQRF 6.6-10.0) (p≤0.001). No unsafe defibrillation practices were observed. In this observational study of defibrillation performance, the use of the C.O.A.C.H.E.D. cognitive aid was associated with a significant decrease in the length of peri-shock pause. Therefore, we conclude that the use of a cognitive aid is appropriate for teaching and performing defibrillation.
