Optimizing Integration of CPR Feedback Technology With CPR Coaching for Cardiac Arrest

Overview

There is significant data showing that the quality of CPR performed is quite poor. Recent studies have shown that when real-time visual corrective feedback is available to CPR providers, quality (compression depth and rate) improves. Pilot work at John's Hopkins Children's Hospital indicates that providing a CPR Coach whose role it is to provide real-time coaching during cardiac arrest, further improves the quality of CPR. This study will assess the impact of a CPR Coach for improving CPR quality and CPR perception in a team of healthcare providers during simulated CPA.

Cardiopulmonary resuscitation (CPR) is provided for thousands of children with cardiopulmonary arrests (CPA) each year in North America. The quality of CPR directly impacts hemodynamics, survival, and neurologic outcome following cardiac arrest. Well-trained healthcare providers consistently fail to perform CPR within established Heart and Stroke Foundation of Canada (HSFC) resuscitation guidelines. The poor quality of healthcare provider CPR adversely affects survival outcomes and quality of life in cardiac arrest survivors. CPR feedback devices that provide real-time visual corrective feedback during CPA have become valuable tools to help to improve the overall quality of CPR. The cardiac arrest literature shows that although CPR feedback devices help to improve the overall quality of CPR, there is still substantial room for improvement. A recent multicenter study involving ten pediatric institutions led by the principal investigator of this project evaluated the impact of CPR feedback on CPR quality during simulated CPA5. This study demonstrated that the use of CPR feedback improved depth compliance by 15.4% and rate compliance by 40.1%. However, overall compliance with guidelines in the CPR feedback group was still under 40% for depth and under 75% for rate. Data collected by this research team suggests that a variety of factors may influence the effectiveness of real-time CPR feedback. CPR providers interviewed after a simulated cardiac arrest report that they often are distracted by other events while providing CPR, are unable to clearly see the device, or have difficulty interpreting the visual display on the CPR feedback device. Additionally, many providers' perception of CPR quality is inaccurate, with providers consistently overestimating the quality of CPR provided during simulated CPA, even when using CPR feedback. This suggests a need to improve provider perception of CPR and provider awareness of the CPR feedback device. To improve the quality of CPR the investigators propose the implementation of a standardized resuscitation team structure with a CPR coach. To date, there have been no studies describing the optimal team structure required for integration of CPR feedback defibrillators during CPA. In this study,the investigators propose the concept of a CPR coach, whose primary responsibility is to provide real-time coaching during cardiac arrest to improve the quality of CPR. Preliminary pilot work done in the intensive care unit at Johns Hopkins Children's Hospital suggests that use of a CPR coach improves the quality of CPR in comparison prior teams that functioned without a CPR coach. This study will assess the impact of a CPR Coach for improving CPR quality and CPR perception in a team of healthcare providers during simulated CPA.
