Survival for in-hospital cardiac arrest (IHCA) has declined since the COVID-19 pandemic. Because the burden of COVID-19 was uneven throughout the U.S., it remains unknown if top-performer hospitals in IHCA survival have remained top-performers since the pandemic. ⋯ Although the COVID-19 pandemic affected the U.S. unevenly, there was good correlation in a hospital's performance for IHCA survival before and after the pandemic, even at hospitals caring for a larger proportion of Black and Hispanic patients. Future studies are needed to understand what characteristics of high-performing hospitals pre-pandemic allowed many to continue to excel in the post-pandemic period.

Outcomes and susceptibility to out-of-hospital cardiac arrest (OHCA) are known to differ by sex, yet little is known about changes in sex hormones after OHCA. We sought to determine the trajectory of sex hormones after OHCA and their association to survival and neurological outcome. ⋯ Survivors and those with favorable neurological outcome had lower trend in estrone. The sex hormone estrone, present in both males and females, may be a predictor of survival. When adjusted for estrogens, female sex had better neurological recovery compared to males. The difference in neurological outcome by sex is not explained by estrogens. However, these finding open the door for exploration of other sex-specific pathways in resuscitation after OHCA.

Randomized Controlled Trial Multicenter Study
Association between early airway intervention in the pre-hospital setting and outcomes in out of hospital cardiac arrest patients: A post-hoc analysis of the Target Temperature Management-2 (TTM2) trial.
Airway management is a critical component of out-of-hospital cardiac arrest (OHCA) resuscitation. The primary aim of this study was to describe pre-hospital airway management in adult patients post-OHCA. Secondary aims were to investigate whether tracheal intubation (TI) versus use of supraglottic airway device (SGA) was associated with patients' outcomes, including ventilator-free days within 26 days of randomization, 6 months neurological outcome and mortality. ⋯ In the multicentre randomized TTM2-trial including patients with OHCA, most patients received prehospital endotracheal intubation to manage their airway. The choice of pre-hospital airway device was not independently associated with patient clinical outcomes.

Regionalisation and organised pathways of care using specialist centre hospitals can improve outcomes for critically ill patients. Cardiac arrest centre hospitals (CAC) may optimise the delivery of post-resuscitation care. The International Liaison Committee on Resuscitation (ILCOR) has called for a review of the current evidence base. ⋯ This review supports a weak recommendation that adults with out-of-hospital cardiac arrest are cared for at CACs based on very low certainty of evidence. Randomised evidence has not confirmed the benefits of CACs found in observational studies, however this RCT was a single trial in a very specific setting and a population without ST elevation on post-ROSC ECG. The role of CACs in shockable and non-shockable subgroups, direct versus secondary transfer, as well as the impact of increased transport time and bypassing local hospitals remains unclear.
