Long-term Mortality, Readmission, and Resource Utilization Among Hospital Survivors of Out-of-Hospital Cardiac Arrest.

Background: Among patients with out-of-hospital cardiac arrest (OHCA), the influence of pre- and in-hospital factors on long-term survival, readmission, and resource utilization is ill-defined, mainly related to challenges combining disparate data sources.

Methods: Adult nontraumatic OHCA from the British Columbia Cardiac Arrest Registry (January 2009 to December 2016) were linked to provincial datasets comprising comorbidities, medications, cardiac procedures, mortality, and hospital admission and discharge. Among hospital-discharge survivors, the 3-year end point of mortality or mortality and all-cause readmission was examined with the use of the Kaplan-Meier method and multivariable Cox regression model for predictors.

The association of scene-access delay and survival with favourable neurological status in patients with out-of-hospital cardiac arrest.

Background: Rapid emergency medical service (EMS) response after out-of-hospital cardiac arrest (OHCA) is a major determinant of survival, however this is typically measured until EMS vehicle arrival. We sought to investigate whether the interval from EMS vehicle arrival to patient attendance (curb-to-care interval [CTC]) was associated with patient outcomes.

Methods: We performed a secondary analysis of the "CCC Trial" dataset, which includes EMS-treated adult non-traumatic OHCA.

North American validation of the Bokutoh criteria for withholding professional resuscitation in non-traumatic out-of-hospital cardiac arrest.

Background: Certain subgroups of patients with out-of-hospital cardiac arrest (OHCA) may not benefit from treatment. Early identification of this cohort in the prehospital (EMS) setting prior to any resuscitative efforts would prevent futile medical therapy and more appropriately allocate EMS and hospital resources. We sought to validate a clinical criteria from Bokutoh, Japan that identified a subgroup of OHCAs for whom withholding resuscitation may be appropriate.
