This study evaluated the association between patient race/ethnicity and the odds of AED provision by a lay rescuer in out-of-hospital cardiac arrest (OHCA) in the United States. ⋯ When compared to White persons, the odds of lay rescuer AED use in OHCA was between 31-38% lower for American Indian/Alaskan Native, Asian, Hispanic, and Native Hawaiian/Pacific Islander persons, and 10% higher for Black persons.

Post-cardiac arrest patients are vulnerable to hypoxic-ischaemic brain injury (HIBI), but HIBI may not be identified until computed tomography (CT) scan of the brain is obtained post-resuscitation and stabilization. We aimed to evaluate the association of clinical arrest characteristics with early CT findings of HIBI to identify those at the highest risk for HIBI. ⋯ Signs of HIBI are commonly seen on CT head within 6 hours of OHCA, occurring in approximately half of patients, and are associated with CPR duration. Determining risk factors for abnormal CT findings can help clinically identify patients at higher risk for HIBI and target interventions appropriately.
