Abstract
BACKGROUND: Chronic hepatitis C virus infection in the pediatric patients is commonly encountered by clinicians, and although interferon-based therapy has been shown to be reasonably effective in children no formal economic analysis of such treatment strategies is available. METHODS: With a Markov cycle tree simulation model, a cost effectiveness analysis was done to compare interferon-based treatment strategies for chronic HCV infection in children with a strategy of no treatment in a cohort of 10-year-old otherwise healthy children. Clinical probabilities used in the model was obtained from available literature, and cost estimates were obtained from two teaching hospitals. Cost per patient, quality-adjusted life years gained in each strategy and incremental cost-effective ratio were the primary outcome measures compared. RESULTS: In the baseline analysis the treatment strategies dominated the strategy of no treatment. A 12-month treatment strategy was better than the 6-month treatment strategy. Combination therapy for 6 months with interferon and ribavirin was at least equally if not more effective than 12-month monotherapy. All treatment strategies decreased the number of patients developing decompensated cirrhosis, hepatocellular carcinoma and also number of orthotopic liver transplants in the lifetime of the model cohort. CONCLUSIONS: Interferon-based treatment strategies were more effective in terms of quality-adjusted life years saved and at the same time cheaper when compared with the strategy of no treatment. Combination therapy may be more cost-effective than interferon monotherapy, and clinical trials of combination therapy in pediatric patients are needed.
