Hepatitis B Virus-related Care Quality in Patients With Hepatitis B/Human Immunodeficiency Virus Coinfection Versus Hepatitis B Monoinfection: A National Cohort Study.

Abstract

Guideline-adherent hepatitis B virus (HBV) care is critical for patients with HBV, particularly patients with HBV-human immunodeficiency virus (HIV) given increased risks of liver-related complications. However, a comprehensive assessment of HBV-related care in patients with HBV-HIV is lacking. We retrospectively assessed adherence to HBV-related care guidelines in all patients with HBV-HIV and HBV monoinfection (HBV-M) in the national Veterans Health Administration healthcare system in 2019. We identified 1021 patients with HBV-HIV among 8323 veterans with chronic HBV. Adherence to HBV guidelines was similar or better in HBV-HIV versus HBV-M, including HBV treatment (97% vs 71%), biannual hepatocellular carcinoma (HCC) surveillance (55% vs 55%) for patients with cirrhosis, hepatitis A virus screening (69% vs 56%), hepatitis C virus screening (100% vs 99%), and on-therapy alanine aminotransferase monitoring (95% vs 96%). Compared with those seeing gastroenterology (GI) or infectious diseases (ID) providers, patients without specialty care were less likely to receive antiviral treatment (none, 39%; GI, 80%; ID, 84%) or HCC surveillance (none, 16%; GI, 66%; ID, 47%). These findings persisted in multivariable analysis. Compared with ID care alone, a higher proportion of patients with HBV-HIV seen dually by GI and ID received HCC surveillance (GI + ID 73% vs ID 31%) and on-therapy HBV-DNA monitoring (GI + ID, 82%; ID, 68%). Patients with HBV-HIV received similar or higher rates of guideline-adherent HBV-related care than patients with HBV-M. Patients with HBV-HIV under dual GI and ID care achieved higher quality care compared with ID care alone. Specialty care was independently associated with higher quality HBV care in patients with HBV-HIV and HBV-M.
