Resuscitation
-
Extracorporeal cardiopulmonary resuscitation (ECPR) is the emerging resuscitative strategy to save refractory ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT) patients. We investigated whether the receiving hospitals' ECPR capabilities are associated with outcomes in out-of-hospital cardiac arrest (OHCA) patients who have refractory VF or pulseless VT. ⋯ Hospitals' ECPR capabilities were associated with favourable neurologic outcomes in OHCA patients who had refractory VF or pulseless VT. We should take each hospital's ECPR capability into consideration when developing a regional system of care for OHCA.

Observational Study
Reasons for death in patients successfully resuscitated from out-of-hospital and in-hospital cardiac arrest.
There is no standard for categorizing reasons for death in those who achieve return of spontaneous circulation (ROSC) after cardiac arrest but die before hospital discharge. Categorization is important for comparing outcomes across studies, assessing benefits of interventions, and developing quality-improvement initiatives. We developed and tested a method for categorizing reasons for death after cardiac arrest in both in-hospital (IHCA) and out-of-hospital (OHCA) arrests. ⋯ Categorizing reasons for death after cardiac arrest with ROSC is feasible using our proposed categories, with substantial inter-rater agreement. Neurologic withdrawal of care is much less common in IHCA than OHCA, which may have implications for further research.

Extracorporeal cardiopulmonary resuscitation (ECPR) is a resource-intensive tool that provides haemodynamic and respiratory support in patients who have suffered cardiac arrest. In this study, we investigated the cost-utility of ECPR (cost/QALY) in cardiac arrest patients treated at our institution. ⋯ The calculated cost-utility is within the threshold considered cost-effective in the United States (<$150,000/QALY gained). These results are comparable to the cost-effectiveness of heart transplantation for end-stage heart failure. Larger studies are needed to assess the cost-utility of ECPR and to identify whether other factors, such as patient characteristics, affect the cost-utility benefit.
