Abstract | Objectives: To estimate the comprehensive value of direct-acting antivirals (DAAs) for the treatment of hepatitis C virus (HCV) compared with peginterferon alfa and ribavirin (PEG/riba) employing a generalized cost-effectiveness analysis (GCEA). Study design: To assess the societal-level cost-effectiveness of DAA treatment for HCV, we extended a previously published discrete-time Markov simulation model of HCV transmission and progression to include market dynamics and broader elements of value. Methods: We followed a stepwise process to add novel value elements to a traditional CEA model for HCV treatments. For each additional element of value, we estimated incremental cost-effectiveness ratios (ICERs) of DAAs compared with PEG/riba. Results: The health technology assessment (HTA)-style model yielded an ICER value of $64,512 per quality-adjusted life-year (QALY). Adding transmission dynamics resulted in an ICER value of $52,971 per QALY, whereas accounting for transmission dynamics and dynamic price and efficacy further decreased ICER values by 90% to $6406 per QALY. Incorporating genericization, productivity loss, caregiver spillover, and differential valuations of LYs vs quality of life, disease severity, and insurance value further decreased the ICER value to $4487 per QALY, a 93% reduction from the baseline HTA-style CEA to the fully realized GCEA. Conclusions: Our GCEA study results confirm that DAAs are a cost-effective treatment for HCV compared with PEG/riba even when using conventional cost-effectiveness approaches. Incorporating broader elements of value resulted in more than a 10-fold improvement in cost-effectiveness, emphasizing the substantive impact of a generalized approach and the importance of incorporating GCEAs into decision-making. |
