Participant Flow

Subjects were recruited over a 3-year period (2007-2010) from a substance abuse treatment clinic in New Haven, CT. Those with evidence of infection with HCV were subsequently seen by a medical provider to evaluate for HCV treatment, and if found to be appropriate, were referred to the research assistant.

Subjects were eligible for participation if they were prescribed methadone and were opioid negative in the past 30 days, age 18 years or older, underwent documented HIV testing, competent to provide informed consent, had stable mental health status, and met the following criteria for HCV treatment: detectable HCV RNA and genotype testing.

Measure
Modified Directly Observed Therapy (mDOT)
Subjects received modified directly observed therapy (mDOT) as part of an adherence intervention. Clinical nurses administered all methadone doses and co-administered the morning weight-based ribavirin (RBV) dose. The evening dose of RBV was prepackaged by a pharmacist accessible for the subject to self-administer 12 hours later. Pegylated interferon alfa-2a(PEG) was administered to mDOT subjects weekly by a licensed practitioners. All mDOT subjects who earned take-home bottles for methadone also received take-home doses of RBV.
Self-Administered Therapy (SAT)
Subjects received their methadone remote from their site of HCV treatment. HCV treatment was provided within the Yale Liver Center, the university-based liver specialty clinic. All subjects in this arm were taught how to self-administer therapy (SAT), the pegylated interferon alfa-a (PEG) and weight-based ribavirin (RBV). Subjects followed a pre-specified time period of attending the Liver Center for clinical follow-up and blood work.
