Assessing Long-term CTN 0049 Outcomes, HCV Prevalence and Progression Along the HCV Care Continuum Among HIV/HCV Co-infected Substance Users in the U.S.

Primary Objective: This study will evaluate the effectiveness of an HCV Care Facilitation intervention in moving HIV/HCV co-infected substance users forward along the HCV care continuum (compared with a Control group). Primary Hypothesis: The number of steps achieved along the HCV care continuum will differ between the two study groups over the 14-month follow-up period. Secondary Objectives: Component 1 (Long-term CTN 0049 follow-up): Using the CTN 0064 baseline data (self-report, medical record abstraction and biological data), the following CTN 0049 primary and secondary outcomes in participants who consented to the CTN 0064 protocol will be re-analyzed to evaluate latent and/or enduring effects of the CTN 0049 interventions: 1. HIV virological suppression 2. HIV primary care visit attendance 3. All-cause mortality
