Trends in aetiology‐based hospitalisation for cirrhosis before and during the COVID‐19 pandemic in the United States.

Summary: Background and Aims: Patients with pre‐existing cirrhosis and exposure to coronavirus disease‐19 (COVID‐19) may portend a poor prognosis. We evaluated the temporal trends in aetiology‐based hospitalisations and potential predictors of in‐hospital mortality in hospitalisation with cirrhosis before and during the COVID‐19 pandemic. Methods: Based on the US National Inpatient Sample 2019–2020, we determined quarterly trends in aetiology‐based hospitalisations with cirrhosis and decompensated cirrhosis and identified predictors of in‐hospital mortality in hospitalisation with cirrhosis. Results: We analysed 316,418 hospitalisations, representing 1,582,090 hospitalisations with cirrhosis. Hospitalisations for cirrhosis increased at a relatively higher rate during the COVID‐19 era. Hospitalisation rates for alcohol‐related liver disease (ALD)‐related cirrhosis increased significantly (quarterly percentage change [QPC]: 3.6%, 95% CI: 2.2%–5.1%), with a notably higher rate during the COVID‐19 era. In contrast, hospitalisation rates for hepatitis C virus (HCV)‐related cirrhosis decreased steadily with a trend of −1.4% of QPC (95% CI: −2.5% to −0.1%). Quarterly trends in the proportion of ALD‐ (QPC: 1.7%, 95% CI: 0.9%–2.6%) and nonalcoholic fatty liver disease‐related (QPC: 0.7%, 95% CI: 0.1%–1.2%) hospitalisations with cirrhosis increased significantly but declined steadily for viral hepatitis. The COVID‐19 era and COVID‐19 infection were independent predictors of in‐hospital mortality during hospitalisation with cirrhosis and decompensated cirrhosis. Compared with HCV‐related cirrhosis, ALD‐related cirrhosis was associated with a 40% higher risk of in‐hospital mortality. Conclusion: In‐hospital mortality in cirrhosis was higher in the COVID‐19 era than in the pre‐COVID‐19 era. ALD is the leading aetiology‐specific cause of in‐hospital mortality in cirrhosis with an independent detrimental impact of the COVID‐19 infection. [ABSTRACT FROM AUTHOR]
