BACKGROUND AND AIMS: We assessed the clinical and economic impact of direct‐acting antiviral (DAA) therapy for hepatitis C virus (HCV) in England, Italy, Romania and Spain. METHODS: An HCV progression Markov model was developed considering DAA eligibility and population data during the years 2015‐2019. The period of time to recover the investment in DAAs was calculated as the cost saved by avoiding estimated clinical events for 1000 standardized treated patients. A delayed treatment scenario because of coronavirus disease (COVID‐19) was also developed. RESULTS: The estimated number of avoided hepatocellular carcinoma, decompensated cirrhosis and liver transplantations over a 20‐year time horizon was: 1,057 in England; 1,221 in Italy; 1,211 in Romania; and 1,103 in Spain for patients treated during 2015‐2016 and 640 in England; 626 in Italy; 739 in Romania; and 643 in Spain for patients treated during 2017‐2019. The cost‐savings ranged from € 45 to € 275 million. The investment needed to expand access to DAAs in 2015‐2019 is estimated to be recovered in 6.5 years in England; 5.4 years in Italy; 6.7 years in Romania; and 4.5 years in Spain. A delay in treatment because of COVID‐19 will increase liver mortality in all countries. CONCLUSION: Direct‐acting antivirals have significant clinical benefits and can bring substantial cost‐savings over the next 20 years, reaching a Break‐even point in a short period of time. When pursuing an exit strategy from strict lockdown measures for COVID‐19, providing DAAs should remain high on the list of priorities in order to maintain HCV elimination efforts.
