We aimed to study sex differences in long-term survival following out-of-hospital cardiac arrest (OHCA) compared to the general population, and determined associations for comorbidities, social characteristics, and resuscitation characteristics with survival in women and men separately. ⋯ Women survived longer than men post-OHCA. Several characteristics were associated with long-term post-OHCA survival, with some sex-specific characteristics. In both sexes, these characteristics had low predictive potential.

According to the Utstein Registry Template for in-hospital cardiac arrest (IHCA), a good neurological outcome is defined as either Cerebral Performance Category (CPC) 1-2 at discharge from hospital or unchanged CPC compared to baseline. However, the latter alternative has rarely been described in IHCA. This study aimed to examine CPC at admission to hospital, the occurrence of post-arrest neurological deterioration, and the factors associated with such deterioration. ⋯ Most patients had preserved neurological function compared to admission. Factors associated with deteriorated neurological function are mainly concordant with established risk factors for adverse outcomes and are primarily intra-arrest and post-resuscitation, making deterioration hard to predict. Further, every tenth survivor was admitted with CPC more than 1, stressing the use of unchanged CPC as an outcome in IHCA.

Optimal timing for subsequent defibrillation attempts for Out-of-hospital cardiac arrest (OHCA) patients with recurrent VF/pVT is uncertain. We investigated the relationship between VF/pVT duration and return of spontaneous circulation (ROSC) in OHCA patients with recurrent shockable rhythms. ⋯ Every one-minute increase in intra-arrest VF/pVT duration was associated with a statistically significant 19% decrease in the chance of achieving ROSC. This highlights the importance of reducing time to shock in managing recurrent VF/pVT. The findings suggest reevaluating the current recommendations of two minutes intervals for rhythm check and shock delivery.
