Guidelines recommend use of computerized tomography (CT) and electroencephalography (EEG) in post-arrest prognostication. Strong associations between CT and EEG might obviate the need to acquire both modalities. We quantified these associations via deep learning. ⋯ CT and EEG provide complementary information about post-arrest brain injury. Our results do not support selective acquisition of only one of these modalities, except in the most severely injured patients.

Point-of-care ultrasound (POCUS) is used in cardiac arrest patients to assess for reversible causes. We aimed to conduct a diagnostic test accuracy systematic review of intra-arrest POCUS to indicate the etiology of cardiac arrest in adults in any setting. ⋯ It is feasible to identify reversible causes of cardiac arrest with POCUS, but the current literature is heterogenous with high risks of bias, wide confidence intervals, and very low certainty of evidence, which render these data difficult to interpret.

The optimal locations and cost-effectiveness of placing automated external defibrillators (AEDs) for out-of-hospital cardiac arrest (OHCAs) in urban residential neighbourhoods are unclear. ⋯ The systematic deployment of AEDs at schools and community centers in urban neighbourhoods may result in increased application and be a cost-effective public health intervention.

The Australasian Resuscitation Outcomes Consortium (Aus-ROC) out-of-hospital cardiac arrest (OHCA) Epistry (Epidemiological Registry) now covers 100% of Australia and New Zealand (NZ). This study reports and compares the Utstein demographics, arrest characteristics and outcomes of OHCA patients across our region. ⋯ OHCA across Australia and NZ has varied incidence, characteristics and survival. Understanding the variation in survival and modifiable predictors is key to informing strategies to improve outcomes.

There have been limited large scale studies assessing sex disparities in the outcomes of cardiac arrest (CA) complicating acute myocardial infarction (AMI). ⋯ Despite no difference in guideline recommendations for men and women with AMI-CA, there appears to be a systematic difference in the use of evidence-based care that disadvantages women.
