Defibrillator Training in the Virtual Setting is Feasible and Improves Medical Student Self-Efficacy; A Pilot Study

Abstract

Background Management of in-hospital cardiac arrest includes many component skills that require considerable training in order to gain mastery. Practicing defibrillation skills in a simulated setting improves performance and time to shock delivery but is cumbersome and costly. Virtual reality (VR) simulation training may provide an alternative platform to help medical students learn and build confidence in the critical steps required to operate a manual defibrillator. Intervention We performed a pilot study to implement a VR simulation that trains learners on the stepwise operation of a manual defibrillator. Methods We conducted a cross-sectional survey that measured the feasibility, usability, and likeability of a VR simulation among fourth-year medical students at a large urban academic medical center. Secondary outcomes included self-efficacy with operating a defibrillator before and after the VR simulation, and time to defibrillation within the simulation. Results Twenty-six participants completed the VR simulation. The majority of participants found the VR simulation easy to use (71% agreed), liked the experience (96% agreed), found it realistic (87.5% agreed), and would recommend it to their peers (96% agreed). Most students (96%) agreed that the training improved their knowledge of how to use a defibrillator, and all (100%) students agreed that they were more confident than beforehand in using the defibrillator to defibrillate a patient with cardiac arrest. Self-reported knowledge and comfort with using the defibrillator significantly improved from before to after the VR training, as did average time to defibrillation. Discussion VR simulation for defibrillator training is feasible and well-liked by senior medical students and is associated with improved self-perceived knowledge and comfort with using a manual defibrillator.
