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

Area of Science:

• Cardiology
• Health Services Research
• Health Equity

Background:

• Little is known about survival outcomes for Hispanic and Asian patients following in-hospital cardiac arrest.
• These populations represent fast-growing demographics in the United States.

Purpose of the Study:

• To compare survival outcomes of Hispanic and Asian patients to White patients after in-hospital cardiac arrest.
• To investigate secondary outcomes including return of spontaneous circulation and favorable neurologic survival.

Main Methods:

• Utilized data from the Get With The Guidelines-Resuscitation registry (2005-2023).
• Included Asian, Hispanic, and White adults experiencing in-hospital cardiac arrest.
• Employed multivariable models to compare survival rates, adjusting for hospital site.

Main Results:

• Hispanic and Asian patients had lower survival to discharge rates (19.4% and 17.8%) compared to White patients (22.0%).
• No significant differences were observed in sustained return of spontaneous circulation.
• Asian and Hispanic patients showed lower rates of favorable neurologic survival (13.2% and 15.4%) versus White patients (18.3%).

Conclusions:

• Hispanic and Asian patients experienced reduced overall survival and favorable neurologic survival post-cardiac arrest compared to White patients.
• Hospital-level factors partially accounted for the observed survival disparities.
