Abstract

Direct-acting antiviral (DAA) drugs are highly effective in curing hepatitis C virus (HCV) infection. Previous simulations showed extended life as a key health advantage of DAA drugs, but real-world evidence on the association between DAA treatment and reduced mortality is limited. To examine the association of DAA treatment with mortality among Medicare beneficiaries with hepatitis C. This cohort study used Medicare claims data of beneficiaries who sought hepatitis C care for the first time between January 1, 2014, and December 31, 2016, after at least a 1-year washout period. Medicare Part D files were used in identifying DAA therapy initiation and completion. Death dates, demographic data, and indicators of health risks were obtained from the Master Beneficiary Summary Files. Beneficiaries with hepatitis C were considered as patients with DAA treatment if they initiated DAA therapy during the study period. Beneficiaries with hepatitis C who did not initiate DAA therapy during the study period were considered as patients without DAA treatment. Patients without DAA treatment were selected using 1-to-1 propensity score matching. Data were analyzed between September 1, 2019, and March 31, 2020. Completion of DAA treatment.
