Can we afford not to screen and treat hepatitis C virus infection in Canada

Background Screening for hepatitis C virus (HCV) followed by direct-acting antiviral (DAA) treatment in individuals born between 1945 and 1964 has been shown to be both effective and cost-effective, but the question of affordability remains unresolved. We looked at long-term cost and health outcomes of HCV screening for Ontario up to 2030. Methods We used a validated state-transition model to analyze the budget and health impact of HCV screening followed by DAA treatment in individuals born between 1945 and 1964 versus current practice. We used a payer’s perspective, discounting costs at an annual rate of 1.5%. Costs, liver-related deaths, and hepatocellular carcinoma (HCC) and decompensated cirrhosis (DC) cases detected were measured over a 14-year period. Results By 2030, the cost of implementing a HCV screening program for individuals born between 1945 and 1964 will add an additional $845 million to the Ontario health care budget. Sensitivity analyses showed that DAA costs had the largest effect on the...
