Is neighborhood socioeconomic vulnerability index (SVI) associated with emergency medical services (EMS) intra-arrest transport for adults with out-of-hospital cardiac arrest (OHCA)?In this cohort study of 61 524 patient encounters for nontraumatic OHCA, patients in neighborhoods with the most vulnerable SVI quartile had greater adjusted odds of receiving intra-arrest transport than patients in neighborhoods with the least vulnerable SVI quartile.The findings suggest that EMS transport practices for OHCA may contribute to socioeconomic disparities in OHCA outcomes.
