Background/Objective: Several million people in the United States are infected with Hepatitis B virus (HBV) or Hepatitis C virus (HCV), both viral liver infections that can lead to cirrhosis or liver cancer. Characteristics of Allegheny County residents hospitalized with HBV or HCV from 2016 through 2019 were examined in order to identify groups at highest risk.
Methods: Statistical Analysis Software (SAS) was used to analyze patient de-identified data from the Pennsylvania Health Care Cost Containment Council datasets, which include up to 18 diagnosis codes. Only hospitalizations of Allegheny County residents with an HBV or HCV ICD-10 diagnosis code, and an admission date from 2016 through 2019, were included. SAS was used to determine the number of hospitalizations for each infection type, sex, race, and age group. The rate of hospitalizations per 100,000 population was calculated, and the percentage of hospital admissions that had an HBV or HCV diagnosis code was calculated for each year.
Results: Hospitalizations with an HCV diagnosis were more common than those with an HBV diagnosis (290.8 hospitalizations per 100,000 population versus 24.4 per 100,000 population). Few HCV and HBV hospitalizations were classified as acute (0.7% for HCV and 2.3% for HBV). Both HCV and HBV hospitalizations were more common in men than women (M:F ratio of 1.4:1 for HCV and 1.7:1 for HBV), and were more common in Black residents than white (B:W ratio of 2.8:1 for HCV and 2.6:1 for HBV). For both HCV and HBV, hospitalizations were most common in the 55 to 64 year age group. Finally, the percentages of hospitalizations with an HBV diagnosis were constant between 2016 and 2019 at around 0.2%, while the percentage of hospitalizations with an HCV diagnosis decreased, from 2.7% in 2016 to 1.8% in 2019.
Conclusion: Overall, this study highlights the public health burden of hospitalizations with an HCV infection and HBV infection in Allegheny County, and illuminates groups that are most affected and that need more support.
