Screening rates for hepatitis B and C among low-income US veterans: Data from the National Veteran Homeless and Other Poverty Experiences Study.

Abstract

Screening for viral hepatitis is considered a high-priority area in the Veterans Health Administration (VHA). Yet, few studies have examined viral hepatitis screening test use among low-income veterans who are considered high-risk with limited healthcare access. Using cross-sectional data from 933 participants in the 2021-2022 National Veteran Homeless and Other Poverty Experiences (NV-HOPE) study, we examined rates and correlates of lifetime screening for hepatitis B (HBV) and hepatitis C (HCV) infections. Multivariable logistic regression models evaluated characteristics associated with HBV/HCV screening. Nearly 16% and 21% reported lifetime HBV and HCV screening, respectively. These rates are considerably lower than HBV (47.3%) and HCV (92.9%) screening rates documented among contemporaneous veterans in VHA electronic health records. In the NV-HOPE data, veterans 50-79 years were more likely than those ≥80 years of age to ever-screen for HBV/HCV. Whereas, household income was inversely related to lifetime screening behaviours, veterans reporting 'other' employment types (vs. full-time/part-time employment) were more likely to ever-screen for HBV/HCV. Ever-screening for HBV was more likely among veterans reporting non-Hispanic 'other' (vs. non-Hispanic 'white') race, housing instability, Medicaid insurance, as well as drug use and cognitive disorder histories. Living with ≥5 members (vs. alone), histories of alcohol use, cancer, and liver disorders were also correlated with ever-screening for HCV. HIV/AIDS history correlated with ever-screening for HBV/HCV. In conclusion, fewer than one-third of low-income US veterans ever-screened for HBV/HCV, with lower screening rates among those less likely to be exposed to viral hepatitis, thereby informing interventions aimed at promoting available screening, treatment and vaccinations for HBV/HCV.
