Bystander CPR and Long-Term Survival in Older Adults With Out-of-Hospital Cardiac Arrest.

ABSTRACT:

Background

Most studies on bystander cardiopulmonary resuscitation (CPR) for out-of-hospital cardiac arrest (OHCA) have focused on in-hospital or short-term survival.

Objectives

The purpose of this study was to examine the association between bystander CPR and long-term survival outcomes for OHCA.

Methods

Within the Cardiac Arrest Registry to Enhance Survival, we identified 152,653 patients with OHCA ≥65 years of age or older. Using multivariable hierarchical logistic regression, we first examined the association between bystander CPR and in-hospital survival. Then, among those surviving to discharge and linked to Medicare files, we evaluated the association between bystander CPR and long-term mortality over 5 years using multivariable Cox regression.
