Multicenter Study Comparative Study
Ethnic differences in sudden cardiac arrest resuscitation.
Ethnic differences in sudden cardiac arrest resuscitation have not been fully explored and studies have yielded inconsistent results. We examined the association of ethnicity with factors affecting sudden cardiac arrest outcomes. ⋯ While there were differences in some prognostic characteristics between blacks, whites and Asians, we did not detect a significant difference in survival following sudden cardiac arrest between the three ethnic groups. There was, however, an ethnic difference in presenting rhythm, with pulseless electrical activity more prevalent in blacks and asystole more prevalent in Asians.

Multicenter Study
Admission of out-of-hospital cardiac arrest victims to a high volume cardiac arrest center is linked to improved outcome.
Cardiac arrest centers have been associated with improved outcome for patients after cardiac arrest. Aim of this study was to investigate the effect on outcome depending on admission to high-, medium- or low volume centers. ⋯ High frequency of post-cardiac arrest treatment in a specialized center seems to be an independent predictor for favorable outcome in an unselected population of patients after out of hospital cardiac arrest.

Multicenter Study Clinical TrialOvercoming Spatial and Temporal Barriers to Public Access Defibrillators Via Optimization.
Immediate access to an automated external defibrillator (AED) increases the chance of survival for out-of-hospital cardiac arrest (OHCA). Current deployment usually considers spatial AED access, assuming AEDs are available 24 h a day. ⋯ One in 5 OHCAs occurred near an inaccessible AED at the time of the OHCA. Potential AED use was significantly improved with a spatiotemporal optimization model guiding deployment.

Prognostic value of gray matter to white matter ratio in hypoxic and nonhypoxic cardiac arrest with noncardiac etiology.
This study evaluated the prognostic performance of the gray to white matter ratio (GWR) on brain computed tomography (CT) in out-of-hospital cardiac arrest (OHCA) survivors with a noncardiac etiology and compared the prognostic performance of GWR between hypoxic and nonhypoxic etiologies. ⋯ A low GWR is associated with poor neurologic outcome in noncardiac etiology OHCA patients treated with targeted temperature management. Gray to white matter ratio can help to predict the neurologic outcome in a cardiac arrest with hypoxic etiology rather than a nonhypoxic etiology.

The association between long duration of resuscitation efforts in out-of-hospital cardiac arrest (OHCA) and neurologic outcome is unclear and understudied with advancements in post-cardiac arrest care and high-quality cardiopulmonary resuscitation. We investigated how downtime, defined as the interval from collapse-to-return of spontaneous circulation (ROSC), impacts on neurologic outcome in OHCA patients treated with targeted temperature management (TTM). ⋯ We found that neurologically intact survival can occur at prolonged downtimes and were unable to identify a downtime for which survivability was clearly futile. These data suggest that downtime should not be considered as a factor in determining whether to provide aggressive post-arrest care, especially in patients with young patients or those with an initially shockable rhythm.
