The proposed study will examine the feasibility, acceptability, safety, effectiveness, and cost of an Accessible Care intervention for engaging people who inject illicit drugs (PWID) in hepatitis C care. Accessible Care for PWID is low-threshold care provided in programs designed specifically for PWID where they can comfortably access care without fear of shame or stigma. Accessible Care will be provided by co-locating a hepatitis treatment provider, together with a Hepatitis C Care Coordinator (HCCC), on-site at a collaborating needle exchange program. The proposed study will compare the effectiveness of Accessible Care with Usual Care (referrals to existing services) in facilitating linkage, engagement, and retention of PWID in care for hepatitis C, addiction, and HIV prevention. The primary outcome is sustained virologic response, which constitutes virologic cure. Substance use and HIV and HCV risk behaviors are secondary outcomes.
