Differential association of prehospital physician presence with outcomes in out-of-hospital cardiac arrest: Secondary analysis of a nationwide registry

The authors aimed to determine whether the presence of a physician during prehospital care affects survival outcomes in patients experiencing out-of-hospital cardiac arrest (OHCA) across various subgroups. Their analysis of a nationwide registry revealed that physician involvement was associated with improved neurological outcomes at 30 days, particularly in patients with unwitnessed arrests, although no significant benefit was observed in those receiving extracorporeal cardiopulmonary resuscitation (ECPR). The authors suggest that these findings warrant further prospective studies to better identify which patient subgroups may benefit most from physician presence.
