Evaluation of the InterFACE-AR System for Cardiopulmonary Arrest

Cognitive aids are decision support tools that present prompts to encourage recall of information, thus freeing up mental resources to increase the likelihood of desired behaviors. Cognitive aids have been trialed in different forms for use during resuscitation, including pocket reference cards and digital apps. Simulation-based studies of cognitive aid used during cardiac arrest events have shown improved adherence to guidelines, improved time to completing critical tasks, and reduced rate of critical errors. Unfortunately, existing pocket reference cards and mobile apps have significant flaws - they all require providers to search through content to identify relevant information.

In the proposed study, the investigators will evaluate the impact of an enhanced system, InterFACE-AR, which provides role-specific decision support to the team leader and medication nurse through AR devices, while concurrently optimizing team situational awareness by displaying a roadmap for patient care on the LCD screen. Clinical data will be collected from the mobile app on a tablet used by the charting nurse. The trial aims to assess the individual and combined effectiveness of InterFACE-AR components (i.e. AR devices and LCD screen) on adherence to AHA resuscitation guidelines during simulated cardiac arrest by conducting a randomized controlled trial with a factorial design.
