Abstract
In the United States, hepatitis D is not a reportable condition, leading to gaps in epidemiological and clinical knowledge. We aim to estimate the incidence of hepatitis D-associated hospitalizations in the United States and describe the clinical, demographic and geographic characteristics of those hospitalizations. We utilized hospitalization data from the 2010-2018 National Inpatient Sample from the Healthcare Cost and Utilization Project. Hepatitis D and hepatitis B only (HBV only) hospitalizations were identified by International Classification of Diseases, Ninth Revision (ICD-9) and International Classification of Diseases, Tenth Revision (ICD-10) codes. We identified 3825 hepatitis D-associated hospitalizations. The hospitalization rate of hepatitis D was between 6.9 and 20.7 per 10,000,000 but did not change significantly over time. Compared to HBV only, the hepatitis D cohort had a greater proportion of males, Hispanics, hospitalizations in the Northeast region. The hepatitis D-associated hospitalizations also had significantly greater frequencies of liver failure, non-alcoholic cirrhosis, portal hypertension, ascites and thrombocytopenia. While mortality in hepatitis D was similar to that of HBV only, age >65 years (odds ratio [OR] = 3.79; p = .020) and having a diagnosis of alcoholic cirrhosis (OR = 3.37; p = .044) increased the odds of mortality within the hepatitis D cohort. Although the hepatitis D-associated hospitalizations were relatively uncommon, they were associated with severe complications.
