What is the impact of jail-based hepatitis C virus (HCV) interventions on HCV elimination outcomes, and are these interventions cost-effective?In this cost-effectiveness analysis using a network simulation model, jail-based HCV interventions reduced HCV incidence and HCV-related deaths among people who inject drugs both within and beyond jail settings by 47% and 40%, respectively, with a cost of $11 000 per quality-adjusted life-year gained compared with the status quo. Additionally, providing treatment in jails yielded greater economic value or cost savings compared with testing alone.Jail-based HCV interventions, particularly those including treatment, substantially improve HCV elimination outcomes in people who inject drugs both within and beyond jail settings and are a cost-effective strategy for public health decision-makers to consider.
