Estimating the Prognosis of Hepatitis C Patients Infected by Transfusion in Canada between 1986 and 1990Toronto General Hospital, ES9 408, 200 Elizabeth Street, Toronto, Ontario M5G 2C4, Canada; murray.krahn{at}uhn.on.ca
Objective.To develop a natural history model for chronic hepatitis C virus (HCV) infection to determine allocation of compensatory funds to Canadians who acquired HCV through the blood supply from 1986 through 1990.Methods. A Markov cohort simulation model for HCV prognosis was developed, using content experts, published data, posttransfusion look-back data, and a national survey. Results.The mortality rate in transfusees is high (46% at 10 years), although HCV-related deaths are rare. Only 14% develop-cirrhosis at 20 years (95% confidence interval, 0%-44%), but 1 in 4 will eventually develop cirrhosis, and 1 in 8 will die of liver disease.Conclusions.This unique application of Markov cohort simulation and epidemiologic methods provides a state-of-the-art estimate ofHCVprognosis and has allowed compensation decisions to be based on the best available evidence.
