Abstract
Background: The provision of high-quality cardiopulmonary resuscitation (CPR) is a significant predictor of survival from cardiac arrest, yet healthcare provider (HCP) CPR quality is known to be poor. Although refresher CPR simulation training has been shown to improve HCP CPR quality, no studies have compared an immersive augmented reality (AR) application to a standard audio-visual feedback (AVF) manikin (Laerdal ResusciAnne) as a refresher training modality. Objectives: We randomized HCPs to refresher CPR simulation training with either a novel AR CPR training application (CPReality, Figure 1) or a validated AVF manikin; both cohorts completed a post-simulation CPR quality evaluation with no feedback immediately following the intervention. We sought to assess the efficacy of AR as a CPR simulation modality compared with an AVF manikin. We hypothesized that the AR application would confer similar skills to the AVF manikin. Results: We enrolled 100 experienced HCPs (e.g. RN, MD, APP) between 1/19-5/19. Mean chest compression (CC) rate for the AR application compared with the AVF manikin was 114±1 vs 121±3 cpm (p<0.01) and CC depth was 52±1 vs 48±1 mm (p<0.01), respectively. Post-simulation mean CC rate for the AR application compared with the AVF manikin was 122±15 vs 117±11 cpm (p=ns), depth was 52±8 vs 49±8 mm (p=ns), and percent with complete recoil was 92±24 vs 88±28 (p=ns), respectively. More AR simulation subjects agreed that the AR simulation provided a realistic patient presence compared to AVF simulation subjects (79% vs. 59%, p=0.07). The majority of CPReality simulation participants agreed or strongly agreed that they would want to use AR modalities for future CPR training (95%). Conclusions: In a post-test scenario, the AR CPR simulation training produced similar CPR quality as the standard AVF manikin in refreshing CPR skills in HCP. Further studies should explore the use of innovative technologies for CPR training. Figure 1 . CPReality (CPReality).
