ABSTRACT For patients with mild chronic hepatitis C the cost effectiveness of antiviral therapy is unknown.
To assess whether antiviral therapy (either interferon alpha or peginterferon alpha combined with ribavirin) is cost effective at a mild stage compared with waiting and only treating those cases who progress to moderate disease.
Cases with mild chronic hepatitis C.
A cost effectiveness model which estimates long term costs and outcomes for patients with mild chronic hepatitis C. The model uses effectiveness and cost data from the UK mild hepatitis C randomised controlled trial, combined with estimates of disease progression and cost from observational studies.
Antiviral treatment at a mild rather than a moderate stage improved outcomes measured by quality adjusted life years (QALYS) gained. The mean cost per QALY gained from antiviral treatment with interferon alpha-2b and ribavirin, compared with no treatment at a mild stage, was 4535 pounds sterling (7108 dollars) for patients with genotype non-1 and 25,188 pounds sterling (39,480 dollars) for patients with genotype 1. Providing peginterferon alpha-2b and ribavirin at a mild rather than a moderate stage was also associated with a gain in QALYS; the costs per QALY gained were 7821 pounds sterling (12,259 dollars) for patients with genotype non-1 and 28,409 pounds sterling (44,528 dollars) for patients with genotype 1.
For patients with chronic hepatitis C, it is generally more cost effective to provide antiviral treatment at a mild rather than a moderate disease stage. For older patients (aged 65 years or over) with genotype 1, antiviral treatment at a mild stage is not cost effective.

    ABSTRACT: Guidelines for good practice in cost-effectiveness analyses (CEAs) are available from the UK's National Institute for Health and Clinical Excellence, which address the scope of the CEA study, appropriateness of the data used and how to account for model as well as statistical uncertainty. Within these three broad headings, we identify 10 specific issues that may affect materially the CEA of a public health intervention for which injecting drug users are a major target group. The 10 issues relate to injecting drug users' under-representation in randomized controlled trials; their risk of blood-borne viruses—such as human immunodeficiency virus and hepatitis C virus—which have long-term chronic sequelae, their markedly higher age-specific mortality than in the general population and the relapsing–remitting nature of opiate dependence with its associated risk of overdose. We consider how adequately three key UK CEAs accounted for the relevant injecting drug user specific issues that we have highlighted. The three case-studies are antiviral treatment of carriage of hepatitic C virus, opiate substitution therapy and needle and syringe programmes.

    ABSTRACT: Hepatitis C virus (HCV) infection is one of the principle causes of chronic liver disease. Successful treatment significantly decreases the risk of hepatic morbidity and mortality. Current standard of care achieves sustained virologic response (SVR) rates of 40-80%; however, the HCV therapy landscape is rapidly evolving. The objective of this study was to quantify the clinical and economic benefit associated with increasing levels of SVR. A published Markov model (MONARCH) that simulates the natural history of hepatitis C over a lifetime horizon was used. Discounted and non-discounted life-years (LYs), quality-adjusted life-years (QALYs) and cost of complication management were estimated for various plausible SVR rates. To demonstrate the robustness of projections obtained, the model was validated to ten UK-specific HCV studies. QALY estimates ranged from 18.0 years for those treated successfully in fibrosis stage F0 to 7.5 years (discounted) for patients in fibrosis stage F4 who remain untreated. Predicted QALY gains per 10% improvement in SVR ranged from 0.23 (F0) to 0.64 (F4) and 0.58 (F0) to 1.35 (F4) in 40 year old patients (discounted and non-discounted results respectively). In those aged 40, projected discounted HCV-related costs are minimised with successful treatment in F0/F1 (at approximately £300), increasing to £49,300 in F4 patients who remain untreated. Validation of the model to published UK cost-effectiveness studies produce R2 goodness of fit statistics of 0.988, 0.978 and of 0.973 for total costs, QALYs and incremental cost effectiveness ratios, respectively. Projecting the long-term clinical and economic consequences associated with chronic hepatitis C is a necessary requirement for the evaluation of new treatments. The principle analysis demonstrates the significant impact on expected costs, LYs and QALYs associated with increasing SVR. A validation analysis demonstrated the robustness of the results reported.

    ABSTRACT: Chronic hepatitis C virus (HCV) infection affects 170 million individuals worldwide. As it is detected incidentally through the evaluation of liver function tests or at the time of blood donor testing, it is usually clinically silent until the advanced stages of liver disease have occurred, when treatment is less effective and shortages of donor liver organs limit the therapeutic options. Combination therapy with ribavirin and pegylated interferon has resulted in sustained viral negative response rates of 54-61%. Because treatment is expensive and not uniformly effective, and because not all chronically infected patients will develop complications, concerns have arisen regarding the cost effectiveness of combination therapy. This paper reviews the public health and individual implications of HCV infections. Because of the latency of infection, numerous country-specific population analyses suggest that HCV will cause an increasing number of liver-related deaths over the next 10 years, despite the dramatic drop in incidence over the past 10-15 years. These deaths will be related to prevalent HCV infection from transfusion and injection drug use prior to identification of the virus and availability of screening tests in the late 1980s and early 1990s. HCV can reduce life expectancy and impair quality of life, yet not all patients will develop progressive liver disease, and antiviral treatment may have associated adverse effects. Finally, to assess the value of antiviral drugs for HCV infection, this paper reviews studies examining the costs of antiviral drugs and of the disease itself along with response to antiviral therapy and the cost effectiveness of antiviral therapy. Although antiviral therapy appears to be expensive, when also considering the likelihood of sustained viral response to therapy, and the cost savings, quality-of-life improvement and prolongation of life expectancy from the prevention of HCV complications, antiviral treatment for HCV appears to be cost effective when compared with other well accepted medical interventions.
