Association between survival and early versus later rhythm analysis in out-of-hospital cardiac arrest: do agency-level factors influence outcomes?

ABSTRACT:

Study objective

Effectiveness of a resuscitation strategy may vary across communities. We hypothesize that a strategy that prioritizes initial emergency medical services (EMS) rhythm analysis (analyze early) will be associated with survival advantage among EMS systems with lower baseline (pretrial) ventricular fibrillation survival, whereas a strategy that prioritizes initial EMS cardiopulmonary resuscitation (analyze late) will be associated with survival advantage among systems with higher ventricular fibrillation baseline survival.

Methods

We conducted a secondary, post hoc study of a randomized trial of out-of-hospital cardiac arrest. Subjects were stratified according to randomization status (analyze early versus analyze late) and EMS agency baseline ventricular fibrill
