Abstract 114: The Effectiveness of Ultra-Brief and Brief Educational Videos for Training Lay Responders in Hands-Only™ Cardiopulmonary Resuscitation: Implications for the Future of Citizen CPR Training
Background: Bystander cardiopulmonary resuscitation (CPR) improves survival from out-of-hospital cardiac arrest (OHCA) but is often not performed. Hypotheses: Subjects viewing very short Hands-Only™ CPR videos will 1) be more likely to attempt CPR in a simulated OHCA scenario, and 2) demonstrate better CPR skills than untrained individuals.
Methods: Prospective trial of 336 adults without recent CPR training, randomized to 4 groups: 1) control (no training) (n=51), 2) 60-second video training (95), 3) 5-minute video (99), 4) 8-minute video including manikin practice (91). All subjects were tested for their ability to perform CPR during an adult OHCA scenario using a CPR sensing manikin and the Laerdal PC SkillReporting™ software. Half of the trained subjects were randomly assigned to testing immediately and half after a 2-month delay.
Results: During the testing, 12 controls (23.5%) did not even attempt CPR. This was true of only 2 subjects (0.7% p =0.01) from any of the experimental groups. In both the immediate and delayed testing groups, all experimental groups had significantly higher average compression rates (closer to the recommended 100/minute) compared to the control group (p<0.001), and all experimental groups had significantly greater average compression depth (>38 mm) compared to the control group (p<0.0001).
Conclusions: Laypersons exposed to very short Hands-Only™ CPR videos are more likely to attempt CPR and display superior CPR skills compared to untrained laypersons. Because the ultra-brief video is short enough to be utilized in a vast myriad of media venues, this method holds promise for increasing bystander CPR rates and survival from OHCA. Since ultra-brief video training requires so little time, it has the potential to facilitate frequent exposure to CPR skills. It also holds promise as a means of reinforcing the skills acquired during formal CPR training.
