Differential effects of out-of-hospital interventions on short- and long-term survival after cardiopulmonary arrest

Survival after out-of-hospital cardiac was characterized by a large number of deaths on day 1. Most subsequent deaths were identified within 14 days after collapse. Prehospital factors have markedly different relationships with short- and long-term survival. Linkage between prehospital intervention and short- and long-term outcomes must consider the survival time characteristics of this population.
