Barriers to dispatcher-assisted CPR are associated with delayed bystander CPR and worse outcomes in out-of-hospital cardiac arrest: A retrospective cohort study.
BACKGROUND Dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) is associated with increased bystander CPR rates after out-of-hospital cardiac arrest (OHCA). We aimed to quantify barriers to DA-CPR occurring after dispatcher recognition of cardiac arrest and estimate their associations with bystander CPR initiati...
