Resuscitation Quality Improvement® (RQI®) HeartCode Complete® program improves chest compression rate in real world out-of hospital cardiac arrest patients

Background: The Resuscitation Quality Improvement® (RQI®) HeartCode Complete® program is designed to enhance cardiopulmonary resuscitation (CPR) training by using real-time feedback manikins. Our objective was to assess the quality of CPR, such as chest compression rate, depth, and fraction, performed on out-of-hospital cardiac arrest (OHCA) patients among paramedics trained with the RQI® program vs. paramedics who were not.

Methods and results: Adult OHCA cases from 2021 were analyzed; 353 OHCA cases were classified into one of three groups: 1) 0 RQI®-trained paramedics, 2) 1 RQI®-trained paramedic, and 3) 2-3 RQI®-trained paramedics. We reported the median of the average compression rate, depth, and fraction, as well as percent of compressions that were between 100 to 120/minute and percent of compressions that were 2.0 to 2.4 inches deep. Kruskal-Wallis Tests were used to assess differences in these metrics across the three groups of paramedics. Of 353 cases, the median of the average compression rate/minute among crews with 0, 1, and 2-3 RQI®-trained paramedics was 130, 125, and 125, respectively (p = 0.0032). Median percent of compressions between 100 to 120 compressions/minute was 10.3%, 19.7%, and 20.1% among crews with 0, 1, and 2-3 RQI®-trained paramedics, respectively (p = 0.0010). Median of the average compression depth was 1.7 inches across all three groups (p = 0.4881). Median compression fraction was 86.4%, 84.6%, and 85.5% among crews with 0, 1, and 2-3 RQI®-trained paramedics, respectively (p = 0.6371).

Conclusions: RQI® training was associated with statistically significant improvement in chest compression rate, but not improved chest compression depth or fraction in OHCA.
