Abstract 289: Temporal Trends In The Incidence And Outcomes Of In-hospital Cardiac Arrest In Patients Hospitalized With Liver Cirrhosis In The Us: Analysis Of The Nationwide Inpatient Sample From 2010-2019

Abstract

Introduction: Liver cirrhosis affects an estimated 1 in 400 adults in the US with significant morbidity and mortality. There is limited data on the incidence and outcomes of in-hospital cardiac arrest (IHCA) in liver cirrhosis-related hospitalizations. Methods: Using the appropriate international classification of disease codes, we queried the nationwide inpatient database to identify patients hospitalized with a primary diagnosis of liver cirrhosis who experienced IHCA and underwent cardiopulmonary resuscitation, between 2010 and 2019, We evaluated the temporal trends in the in-hospital outcomes using Cochrane -Armitage test, and factors associated with survival to hospital discharge using logistic regression analysis. Results: 7,091,054 weighted liver cirrhosis hospitalizations were identified during the study period. The IHCA incidence rate was 1.4% with a mean age (SD) of 59 years (12) and males were predominantly affected (59.9%). There was an upward trend in IHCA incidence during the study period (1.3% in 2010 to 1.5% in 2019, p < 0.001). The overall survival to hospital discharge rate was 22.2%. No significant change in the mortality trend during the study period. Most of the survivors were discharged to a long-term acute care facility (46.4%) followed by home discharge without the need for home health (24.7%) and short-term acute facilities (12.6%). Factors associated with lower odds of survival to hospital discharge were age > 65 years OR 0.71, 95% CI 0.67 - 0.75, P < 0.001), Black (OR 0.94, 95% CI 0.91 - 0.99, P=0.012) and Hispanic race (OR 0.78, 95% CI 0.74 - 0.81, P < 0.001), and severe comorbidity index (OR 0.63, 95% CI 0.59 - 0.65, P < 0.001). Conclusion: Between 2010 and 2019, we found a slight increase in the IHCA incidence rate among patients hospitalized with liver cirrhosis. Only about one out of 5 patients survived hospital discharge, and this did not change during the study period. Low socioeconomic status and higher comorbidity burden were associated with lower odds of survival. More research is needed to identify strategies that may improve survival outcomes in IHCA among liver cirrhosis patients.
