Compared with standard training with a video self-instruction kit, video-only training was noninferior in chest compression rate among individuals being trained in CPR, according to new findings.

The researchers performed a cluster randomized trial of CPR education for relatives of patients with high-risk cardiac conditions. Eight hospitals were randomly assigned to offer video-only training or a video self-instruction kit with a manikin.

Volunteers trained 1,464 individuals, whose skills were assessed 6 months after training, between February 2012 and May 2015. Training occurred before discharge of the high-risk relative. Of those trained, 522 completed the skills assessment.

The primary outcome was mean chest compression rate, with the noninferiority margin defined as eight chest compressions per minute. The secondary outcome was mean chest compression depth.

Among those who completed the skills assessment, mean chest compression rate was 87.7 compressions per minute in the video-only group and 89.3 compressions per minute in the control group (mean difference, –1.6 compressions per minute; 95% CI, –5.2 to 2.1). Audrey L. Blewer, MPH, from the department of emergency medicine and the Center for Resuscitation Science at the University of Pennsylvania, and colleagues wrote that the video-only training met the noninferiority standard.

Mean depth of chest compressions was 40.2 mm in the video-only group and 45.8 mm in the control group (mean difference, –5.6 mm; 95% CI, –7.6 to –3.7), according to the researchers.

Multivariate regression adjustment did not change the results.

“These findings suggest a potential trade-off in efforts for broad dissemination of basic CPR skills; [video-only] training might allow for greater scalability and dissemination, but with a potential reduction in [chest compression] depth,” Blewer and colleagues wrote. – by Erik Swain
