Abstract
Study Objective: This was a registry based retrospective observational cohort study of roughly 1,150 cardiac arrest cases transported by the Tualatin Valley Fire and Rescue emergency medical service (EMS) agency to hospitals in the Portland area from 2018-2019 and from 2022-2023 to compare cardiopulmonary resuscitation (CPR) ventilation policy changes between these two years from continuous chest compressions (CCC) to a compression ventilation ratio of 30:2. Hospital outcomes were linked to EMS records through trauma registries, state discharge and emergency department data. The primary outcome was survival to discharge, and the secondary outcome was positive neurological outcome (Cerebral performance category score of 1 or 2). We performed propensity score matching to control for covariates including witnessed cardiac arrest, location of cardiac arrest, bystander CPR or defibrillation, time to EMS arrival, time to advanced airway, time to EMS provided CPR, cardiac arrest etiology, defibrillation shocks given in the first 5 minutes of CPR, doses of epinephrine given in the first 5 minutes of CPR, and doses of naloxone given in the first 5 minutes of CPR.
Results: 539 patients met the inclusion criteria and 207 were successfully matched with a standard difference of
Conclusions: In a single EMS system comparing cardiac arrest cases from two, two year periods, there was no detectable difference in survival to discharge or neurologic outcome between CPR ventilation policies that promote CCC or 30:2 CPR. This is consistent with previous research by the Resuscitation Outcomes Consortium and suggests further research is needed in order to determine the optimal CPR ventilation strategy. However, it does indicate that no association was observed between survival to discharge and switching CPR ventilation strategy from CCC to 30:2.
