Epidemiology of hepatitis C virus infection in a country with universal access to direct-acting antiviral agents: data for designing a cost-effective elimination policy in Spain

Abstract: Accurate HCV prevalence estimates are necessary for guiding elimination policies. Our aim was to determine the HCV prevalence and assess the cost-effectiveness of a screen-and-treat strategy in the Spanish population. A population-based, cross-sectional study (PREVHEP-ETHON Cohort, Epidemiological sTudy of Hepatic infectiONs; NCT02749864) was performed from July 2015-April 2017. Participants from three Spanish regions were selected using two-stage conglomerate sampling, and stratified by age, with randomized subject selection. Anthropometric and demographic data were collected, and blood samples were taken to detect anti-HCV antibodies/quantify HCV RNA. The cost-effectiveness of the screening strategies and treatment were analysed using a Markov model. Among 12 246 participants aged 20-74 (58.4% females), the overall anti-HCV prevalence was 1.2% (95% CI 1.0-1.4), whereas the detectable HCV-RNA prevalence was 0.3% (0.2-0.4). Infection rates were highest in subjects aged 50-74 years [anti-HCV 1.6% (1.3-1.9), HCV RNA 0.4% (0.3-0.6]. Among the 147 anti-HCV + subjects, 38 (25.9%) had active infections while 109 (74.1%) had been cleared of infection; 44 (40.4%) had cleared after antiviral treatment, whereas 65 (59.6%) had cleared spontaneously. Overall, 59.8% of the anti-HCV + participants were aware of their serological status. Considering a cost of treatment of €7000/patient, implementing screening programmes is cost-effective across all age cohorts, particularly in patients aged 50-54 (negative incremental cost-effectiveness ratio which indicates a cost-saving strategy). The current HCV burden is lower than previously estimated, with approximately 25% of anti-HCV + individuals having an active infection. A strategy of screening and treatment at current treatment prices in Spain is cost-effective across all age cohorts.
