Survival Differences in Asian and Hispanic Patients With In-Hospital Cardiac Arrest

Although they are fast-growing populations in the United States, little is known about survival outcomes of Hispanic and Asian patients after in-hospital cardiac arrest.

In Get With The Guidelines-Resuscitation, we identified Asian, Hispanic, and White adults with in-hospital cardiac arrest during 2005 to 2023. Using multivariable models, we compared rates of survival to discharge separately for Asian and Hispanic patients versus White patients, as well as rates of sustained return of spontaneous circulation for ≥20 minutes and favorable neurologic survival as secondary outcomes. Of 189 557 in-hospital cardiac arrests, 167 640 (88.4%), 16 800 (8.9%), and 5117 (2.7%) patients were White, Hispanic, and Asian, respectively. Compared with the survival rate to discharge for White patients (22.0%), rates were lower for Hispanic (19.4%; adjusted odds ratio [OR], 0.93 [95% CI, 0.89-0.97]; P<0.001) and Asian patients (17.8%; adjusted OR, 0.90 [95% CI, 0.83-0.97]; P=0.008), and these differences were attenuated after accounting for the hospital at which patients received care (adjusted OR: Hispanic patients, 0.95 [95% CI, 0.91-1.00]; Asian patients, 0.91 [95% CI, 0.84-0.99]). Although there were no differences in rates of return of spontaneous circulation between White (68.7%), Hispanic (69.0%), and Asian patients (69.7%), both Asian and Hispanic patients were less likely to have favorable neurologic survival (White: 18.3%; Hispanic: 15.4%; adjusted OR, 0.88 [95% CI, 0.84-0.93]; Asian: 13.2%; adjusted OR, 0.80 [95% CI, 0.73-0.87]). These differences were also attenuated after accounting for hospital site.

Compared with White patients, Hispanic and Asian patients with in-hospital cardiac arrest had lower rates of overall survival and favorable neurologic survival. Some of these differences were associated with the hospital at which patients received care.
