523: EPIDEMIOLOGY AND OUTCOMES OF IN-HOSPITAL CARDIAC ARREST IN SEPSIS: A POPULATION-BASED COHORT STUDY.

IHCA occurred in 12.7% (95% CI 12.4-12.9) of terminal sepsis hospitalizations, with the rate rising between 2014 and 2017 from 10.6% to 15.0%, respectively (odds ratio 1.12 [95% CI 1.09-1.14]). B Introduction: b Sepsis is an underlying condition in up to 27% of in-hospital cardiac arrest (IHCA) patients, with worse short-term outcomes in this subgroup than among non-septic patients. However, data on the epidemiology and outcomes of IHCA in sepsis are limited due to lack of population-level studies focusing specifically on sepsis and use of non-standardized sepsis definitions.
