Abstract
OBJECTIVE: Since July 1, 2011 antiviral therapy for hepatitis B virus infection has been listed as a reimbursable expense for medical insurance in Beijing. This study aimed to assess the impact of this program on liver-related death for patients with chronic hepatitis B (CHB). METHODS: Profiles of patients with CHB discharged between January 2008 and December 2015 were retrieved from the Beijing hospital discharge database. Liver-related deaths in these patients occurring between January 2008 and December 2017 were retrieved by linking them to the death certification database. Liver-related mortality (number of deaths divided by the observed person-years) before and after this program was launched was calculated and compared. A Poisson regression was performed to assess the strength of association (risk ratio [RR]) between the reimbursement program and liver-related mortality. RESULTS: Information on 35 943 discharged patients (17 114 patients with non-cirrhotic and 18 829 with compensated cirrhotic CHB) was retrieved. Altogether 3 832 liver-related deaths during the 190 695 person-years were observed. After the reimbursement program was launched, liver-related mortality per 100 person-years dropped from 0.38% to 0.16% for patients with non-cirrhotic CHB, and from 4.03% to 3.39% for those with compensated cirrhosis. The program was associated with a lower risk of developing liver-related death for patients with non-cirrhotic CHB (RR 0.40, 95% confidence interval [CI] 0.30-0.52) and those with compensated cirrhosis (RR 0.84, 95% CI 0.78-0.89). CONCLUSION: Coverage of antiviral therapy by basic medical insurance reduced the risk of developing liver-related death for patients with non-cirrhotic and with compensated cirrhotic CHB.
