To evaluate 1) the relative use of automated external defibrillators (AEDs) at different types of AED locations 2) the percentage of AEDs crossing location types during OHCA before use 3) the AED coverage distance at different types of AED locations, and 4) the 30-day-survival in different subgroups. ⋯ The relative use of AEDs from public places, nursing homes, sports facilities and health clinics was high, and AEDs used during OHCA in residential areas were most frequently collected from public places. AEDs placed in both residential areas and public places may have a wider coverage area than proposed in current literature.

Prognostication of refractory out-of-hospital cardiac arrest (OHCA) is essential for selecting the population that may benefit from extracorporeal cardiopulmonary resuscitation (ECPR). We aimed to examine the prognostic value of signs of life before or throughout conventional CPR for individuals undergoing ECPR for refractory OHCA. ⋯ The assessment of signs of life before or throughout CPR substantially improves the accuracy of a multivariable prognostic model in predicting 30-day survival with favorable neurological outcome. The lack of any sign of life might obviate the provision of ECPR for patients without shockable cardiac rhythm.

The COVID-19 pandemic has led to closures of non-essential businesses and buildings. The impact of such closures on automated external defibrillator (AED) accessibility compared to changes in foot traffic levels is unknown. ⋯ A majority of AEDs became inaccessible during the COVID-19 pandemic due to government-mandated closures. In a substantial number of locations across Canada, the reduction in AED accessibility was far greater than the reduction in foot traffic.

Studies of pediatric cardiac arrest use inconsistent outcomes, including return of spontaneous circulation and short-term survival, and basic assessments of functional and neurological status. In 2018, the International Liaison Committee on Resuscitation sponsored the COSCA initiative (Core Outcome Set After Cardiac Arrest) to improve consistency in reported outcomes of clinical trials of adult cardiac arrest survivors and supported this P-COSCA initiative (Pediatric COSCA). The P-COSCA Steering Committee generated a list of potential survival, life impact, and economic impact outcomes and assessment time points that were prioritized by a multidisciplinary group of healthcare providers, researchers, and parents/caregivers of children who survived cardiac arrest. ⋯ Cognitive function, physical function, and basic daily life skills are assessed between 6 and 12 months after cardiac arrest. Because many children have prearrest comorbidities, the P-COSCA also includes documentation of baseline (ie, prearrest) brain function and calculation of changes after cardiac arrest. Supplementary outcomes of survival, brain function, cognitive function, physical function, and basic daily life skills are assessed at 3 months and beyond 1 year after cardiac arrest if resources are available.

Out-of-hospital cardiac arrest (OHCA) is highly prevalent among patients with myocardial infarction and cardiogenic shock (MI-CS). We aimed to examine the prognostic importance of OHCA in patients with MI-CS. ⋯ Among patients hospitalized with MI-CS, OHCA did not influence all-cause in-hospital or long-term mortality but was a marker for reduced long-term rates of heart failure hospitalization and cardiovascular mortality. Future randomized studies are needed to improve prognosis of MI-CS, however, the importance of OHCA must be considered.
