Aim of the study: Augmented reality (AR) has the potential to offer a novel approach to CPR training that supplements conventional training methods with gamification and a more interactive learning experience. This is done through computer-generated imagery superimposed on users’ view of the real environment to simulate interactive training scenarios. We sought to test the feasibility of an AR CPR training system (CPReality) for health care providers (HCPs). Methods: In this feasibility trial, a CPR training manikin was integrated with a commercial AR device (Microsoft HoloLens) to provide participants with real-time audio-visual feedback via a holographic overlay of blood flow to vital organs dependent on CC quality. In this system, higher quality CC visually improved virtual blood circulation. HCPs performed a 2-minute cycle of hands-only CPR using only the AR system, and CC parameters were recorded. Descriptive data on participants’ demographics, CC quality, and satisfaction with the training environment were reported using quantitative and qualitative analysis. Results: Between 10/2018–11/2018, we enrolled a convenience sample of 51 HCPs. The median age of participants was 31 years (IQR 27–41), 71% (36/51) were female, and 67% (34/51) were registered nurses. CC rates (mean 126 ± 12.9 cpm), depths (median 53 mm, IQR 46–58), and percent with complete recoil (median 80%, IQR 12–100) were consistent with guideline recommendations for good quality CPR. Participants were predominantly satisfied with the system, with 82% perceiving the experience as realistic, 98% recognizing the visualizations as helpful for training, and 94% willing to use the application in future CPR training. Conclusions: As AR is increasingly applied in the healthcare setting, integration in CPR training offers a novel and promising educational approach. In this convenience sample of trained HCPs, high quality CC delivery was feasible using the AR CPR training system which was received favorably by most participants.

Background: Protocol-based resuscitation strategies in the Emergency Department (ED) improve survival for out-of-hospital cardiac arrest (OHCA) and severe sepsis but implementation has been inconsistent. Objective: To determine the feasibility of a real-time provider-to-provider telemedical intervention for the treatment of OHCA and severe sepsis. Materials and methods: A three-center pilot study utilizing a “hub-spoke model” with an academic medical center acting both as the hub for teleconsultation as well as a spoke hospital enrolling patients. Eligible patients were adults presenting with either return of spontaneous circulation (ROSC) following OHCA or with severe sepsis. Telemedical encounters were monitored for quality of interface and patient level data (demographics, physiologic, laboratory, treatment) were abstracted. Results: Over a 12-week period, there were 80 text alerts. Of 38 OHCA alerts, 13 achieved ROSC (34.2%), 85% underwent teleconsultation (11/13). Of 42 “lactate ≥4 mmol/L” alerts, 33.3% (14/42) were determined to have severe sepsis and underwent teleconsultation. Mean time from OHCA teleconsultation request to live connection: 3.7 min (95% CI 1.6–5.8); mean call duration: 71.7 min (95% CI 34.6–108.8). Mean time from sepsis teleconsultation request to connection: 8.4 min (95% CI 4.5–12.3); mean call duration: 61.5 min (95% CI 37.2–85.8). Discussion: Telemedicine provides a robust and reliable means of quickly bringing expertise virtually to the bedside at the most proximal point in a patient’s hospital care. Conclusions: Real time ED-based telemedical consultation for patients with ROSC after OHCA or severe sepsis has the potential to improve the dissemination and implementation of evidence-based care.
