Just in Time Cardio Pulmonary Resuscitation Trial (JITCPR-T): Comparison of a Brief Video to Traditional CPR Training: a Randomized Controlled Trial

The first responder phase of out-of-hospital cardiac arrest (OHCA) response is most often led by bystanders with limited resources and no medical training. Bystanders play a critical role in the initial measures of the cardiac arrest chain of survival-activation of emergency medical services (EMS), initiation of cardiopulmonary resuscitation (CPR), and administration of defibrillation when indicated. Early bystander response, early bystander CPR, and defibrillation in under 8 minutes are associated with increased survival to hospital discharge.

Despite the clear importance of early bystander response to OHCA, rates of bystander CPR remain low with only one-third of OHCA patients receiving bystander CPR. Lay people with CPR training are more likely to perform CPR than those without training. Prior studies comparing traditional in-person training programs for CPR versus technology-enabled self-instruction (TESI) formats have demonstrated superiority or equivalency of TESI to prepare lay bystanders in OHCA response. Shorter duration and more convenient access to TESI in light of these findings provide a promising opportunity to increase public preparedness to participate in OHCA management at greater scales and lower costs. However, CPR-specific skills and knowledge deteriorate within 3 to 6 months of initial training, and time, location, and duration have all been perceived as barriers to completing CPR training.

The objective is to evaluate the effectiveness of a Just in Time (JiT) video as compared to the AHA Heartsaver® CPR AED Training Course and no training (control) in ability to correctly perform CPR. The secondary objectives are the evaluation participate interaction with the JiT video and to assess skill retention 3-9 months after the AHA Heartsaver course with and without JiT Video use. The goal of this work is to study the effectiveness of this new JiT video to improve objective knowledge- and performance-based measures of effective OHCA response, as well as subjective ratings of preparedness and likeliness to respond, compared to the standard AHA Heartsaver® CPR AED Training course.

This is a prospective, randomized, three arm, open-label trial will two rounds of data collection. In the first round, participants will be randomized to one of three arms (no training, AHA course, JiT video) and assessed on CPR skills and knowledge. All participants will then be exposed to the other conditions (completion of the AHA Heartsaver® CPR AED Training course and viewing of the JiT video). During the second round, approximately 3-12 months later, the investigators will test the effectiveness of the JiT video at prompting correct CPR skills after previous training versus no prompting.

Specific aim 1: Determine the efficacy of an abbreviated JiT video-based curriculum in achieving competence in CPR by lay-persons as compared to individuals trained by the AHA Heartsaver® CPR AED Training course.
