  1. Cost-effectiveness of 6 and 12 months of interferon-alpha therapy for chronic hepatitis C.

    Article - En anglais


    Interferon-alpha is effective in only a small number of patients with chronic hepatitis C, although prolonged treatment may increase the response rate.

    There is concern that the expense of interferon-alpha therapy may not be justified by the low response rates and uncertain long-term benefit.


    To compare clinical and economic outcomes after 6 months and 12 months of interferon-alpha therapy for chronic hepatitis C. Design : A Markov model depicting the natural progression of chronic hepatitis C. On the basis of this model, a simulated trial compared no therapy with 6 and 12 months of interferon-alpha therapy at standard doses (3 million U three times weekly).


    Four age-specific cohorts (30,40,50, and 60 years of age) with chronic hepatitis C. Measurements : Number of deaths from liver disease, total costs, and cumulative quality-adjusted life-years (QALYs).


    Six and 12 months of interferon-alpha treatment gained 0.25 QALYS at an incremental cost of $1000 and 0.37 QALYs at an incremental cost of $1900, respectively.

    Thus, although 6 months of interferon-alpha therapy was less efficacious than 12 months of therapy, it was more cost-effective ($4000 per QALY gained compared with $5000 per QALY gained).

    Nonetheless, in patients younger than 60 years of age, both 6 and 12 months of therapy compared favorably with other established medical interventions, such as screening mammography and cholesterol reduction programs. (...)
