Comparison of inpatient outcomes in patients with Hepatitis B, Hepatitis C, and Hepatitis B and C co-infection with Cirrhosis

Background: Hepatitis B (HBV) and Hepatitis C (HCV) are among the most common causes of cirrhosis in the USA, with high mortality and morbidity but comparative outcomes were not well studied. Methods: We retrospectively analyzed cirrhosis patients with HBV, HCV, and HBV/HCV coinfection from 2016 to 2019 in National Inpatient Sample (NIS) database. Our primary outcome was the length of stay (LOS), mean hospital charge and mortality. Results: Our study included 701464 cirrhosis patients with HCV (89.7%), HBV (6.8%), and coinfection (3.5%) (P < 0.001). Male gender and white race were more common in all three cohorts (p < 0.001). The mean age for HBV, HCV, and coinfection was 55.59, 58.69, and 58.27 years. The mean LOS for HBV, HCV, and coinfection were 6.59 ± 0.1, 6.02 ± 0.03, and 6.74 ± 0.12 days respectively. The adjusted length of stay was 0.62 days longer in the HBV cohort and 0.61 days longer in the coinfection cohort, compared to the HCV cohort (P < 0.001). Adjusted hospital charges were $15112 higher in the HBV cohort and $ 6312 higher in the coinfection cohort, compared to the HCV cohort (P < 0.001). Patients with HBV had a higher risk of mortality compared to HCV infection (AOR 1.35, [1.22-1.48], P < 0.001); However, patients with coinfection had no difference in mortality compared to HCV infection. Conclusion: Cirrhosis with HBV and coinfection is associated with increased duration of hospital stay and cost when compared to HCV infection. There is a higher risk of mortality in cirrhotic patients with HBV infection compared to HCV; however, no significant difference in mortality for coinfection compared to HCV.
