In the study, researchers with UC’s Department of Emergency Medicine approached 50 non-patient emergency department visitors to train them in doing compression-only cardiopulmonary resuscitation (CCPR). Compression-only CPR is recommended by the American Heart Association as the best way to keep someone alive after their heart stops until paramedics arrive because it is easier to remember and does not require “mouth to mouth” breathing.
Self-Reported CPR Training Doesn't Mean Better CPR Performance
Before training, participants filled out a questionnaire about their previous CPR training and confidence of performing CPR. Then they spent 60 seconds performing CPR on a training mannequin and were judged on six components of CPR performance before getting CCPR training.
Participants were measured on the following components: checking the patient for responsiveness, calling for help/911, beginning chest compressions immediately and correct hand placement, compression depth and compression rate.
Among the group, 60 percent of participants reported previous CPR training. While those participants performed more components correctly, no one performed all CPR measures correctly and there was no significant difference in performance between participants with and without prior training.
Researchers also found that correct compression rate and depth were very poor.
“The most effective chest compressions are done at around 100 per minute and are 2 inches deep. Although traditional CPR classes emphasize pushing hard and fast, our subjects almost universally pushed too slow and too soft. Adequate compressions are the most important components of CPR to keep oxygenated blood going to the brain,” says Jason McMullan, MD, assistant professor of emergency medicine at UC and one of the study’s investigators.
Finally, the study found that prior training did not lead to participants reporting a higher confidence or likeliness to perform CPR if needed.
“Bystander CPR can triple the chances of survival after out-of-hospital cardiac arrest. We found that there is a desperate need to train or retrain people better because the current way of training doesn’t obviously increase their skills or confidence. Without getting better training out there, people will continue to die needlessly from cardiac arrest,” says Jennifer Sayegh, the study’s lead investigator.
The team presented their abstract, “Individuals Who Self-Report Previous CPR Training Do Not Demonstrate Higher Performance Confidence or Accuracy,” at the Society for Academic Emergency Medicine annual meeting May 14-18 in Atlanta. Co-authors include McMullan, Sayegh, Kimberly Ward Hart and Christopher Lindsell, PhD.
