Purpose: This study was conducted to investigate if real time audio feedback given to nurses during simulated (cardio-pulmonary resuscitation) CPR sessions could improve quality of compressions.
Background/Significance: Sudden cardiac arrest (SCA) is a leading cause of death in the United States, with a dismal survival rate despite widespread CPR training. Recent investigations have demonstrated that CPR quality is highly variable when performed by trained health care providers. Optimal timing and quality of chest compressions during CPR can more than double the chances of survival from SCA, providing critical therapy that supports cerebral perfusion while improving the likelihood of successful defibrillation.
Methods: A total of 80 nurses were recruited for this study. Nurses were randomly assigned to a control group or experimental group. Both groups were assessed for baseline CPR performance without feedback using a a CPR-sensing defibrillator that measures chest compression rate and depth. The groups were then assessed with or without real time audio feedback. After the simulations, both groups received a five minute debriefing. Both groups then performed CPR during a final round of arrest simulations. CPR quality parameters were collected from a defibrillator memory card. T-tests, chi-square and analysis of variance tests were performed to make intergroup comparisons with a p-value <0.05.
Results: Full data of CPR quality was available for 65 of the original 80 participants. Baseline demographics between the two groups were similar, however the experience caring for critically ill patients were significantly different. There were no significant differences between the first two rounds in the no feedback group. After a verbal debriefing, there were significant improvements in depth, and number of compressions, suggesting that a simple verbal debriefing proves beneficial in improving some aspects of CPR performance. The feedback group also performed CPR during three separated simulated cardiac arrests. Use of the audio feedback resulted in a significant improvement in measures of CPR.
Conclusions: This study suggests that both debriefing sessions as well as real time audio feedback provided improvement in CPR quality measures although the combination provided the most improvement in individual performances.
