Factors associated with shock-refractory prehospital cardiac arrest.

ABSTRACT: A significant number of out-of-hospital cardiac arrest (OHCA) patients experience refractory ventricular arrhythmias despite prompt defibrillation. These refractory arrhythmias are associated with poor clinical outcomes, underscoring the need to investigate improved management strategies. Therefore, this study aimed to identify factors associated with shock-refractory OHCA during the prehospital stages of resuscitation. This multicenter observational study included adult OHCA patients (age ≥ 18 years) from October 2015 to June 2022 who required at least one prehospital defibrillation. This study's primary endpoint was shock-refractory OHCA, defined as three defibrillation shocks during resuscitation. A logistic regression analysis was performed to identify factors associated with shock-ref
