CPC = Cerebral Performance Category, HD = hospital discharge.
aRate of HD with favorable neurologic function among patients with the greatest likelihood of survival, namely those with a witnessed arrest, a first recorded rhythm of either ventricular tachycardia or ventricular fibrillation and those who received bystander cardiopulmonary resuscitation (CPR).
bCardiac Arrest Registry to Enhance Survival rates of survival to hospital discharge with good neurologic function rates remained constant in 2017 and 2018.
Patients with a CPC score of 1 or 2 were considered to have a favorable neurologic outcome. Secondary clinical outcomes included rates of return of spontaneous circulation, overall frequency of hospital discharge, and Utstein 2 Cases. Bystander CPR rates are from 2017. Collective outcome data for the 10 Emergency Medical Services systems are in bold.
