The cost-effectiveness of the new protocol reflecting rapid virologic response to peginterferon alpha-2b and ribavirin for chronic hepatitis C.Nakamura J, Kobayashi K, Toyabe S, Aoyagi Y, Akazawa K Division of Information Science and Biostatistics, Niigata University Graduate School of Medical and Dental Sciences, Niigata, Japan. ichirojn@med.niigata-u.ac.jp OBJECTIVE: Recent studies have reported the effectiveness of shorter courses of treatment with peginterferon alpha-2b plus ribavirin for patients with chronic hepatitis C, who achieved a rapid virologic response (RVR), defined as undetectable hepatitis C virus (HCV-) RNA at week 4. The aim of this study was to evaluate the cost-effectiveness of the new protocol for treatment, from the perspective of RVR. METHODS: A cost-effectiveness analysis based on the rate of sustained virologic response was performed. A Markov cohort model of hepatitis C was constructed to demonstrate the clinical states on the basis of the assigned transition probabilities over 30 years. The treatment strategies were classified into five subgroups taking into consideration the viral genotypes, viral load, and RVR. The lifetime costs and quality-adjusted life years (QALYs) were compared between the new and standard protocols for treatment. RESULTS: Genotype 1-infected patients in the new protocol for treatment compared with the standard one could prolong QALYs by 0.33 and reduce lifetime cost by euro 5993. Genotype 2 or 3-infected patients in the new protocol for treatment compared with the standard one could prolong QALYs by 0.02 and reduce lifetime cost by euro2851. CONCLUSION: Treatment strategies that consider viral load and RVR for patients with a low viral load infected with genotype 1 and those infected with genotype 2 or 3 are more cost-effective compared with the standard protocol for treatment.
