Temporal Trends in Outcomes After Out-of-Hospital Cardiac Arrest Transported to Critical Care Medical Centers in Japan, 2014–2022: A Nationwide Retrospective Observational Study

Key Points

To examine the trends in outcomes for patients who experienced out-of-hospital cardiac arrest transported to critical care medical centers in Japan.
Conducted a nationwide retrospective observational study
Analyzed outcomes from 2014 to 2022
Compared trends before and during the COVID-19 pandemic
Outcomes remained stable until 2019, then declined during the COVID-19 pandemic
Improved outcomes in patients eligible for ECPR
Indicates potential benefits of targeted post-arrest interventions for selected patients.

Abstract

Outcomes among OHCA patients transported to CCMCs remained stable until 2019 but declined during the COVID-19 pandemic period. However, improved outcomes among patients eligible for ECPR suggest that timely and targeted post-arrest interventions may improve outcomes in selected populations.
