Abstract
Injection drug users (IDUs) have the highest rate of HCV infection. Although IDUs need support to access and use HCV services, they often lack this support. Many IDUs, however, have contact with a methadone maintenance treatment program (MMTP) where they can gain access to HCV services and obtain support in using them. Unfortunately, however, IDUs often underutilize the MMTP services that are available to them. Using qualitative data collected in 4 MMTPs, we identify some reasons for clients' lack of HCV service utilization and staff strategies that influence clients' perceptions of support in using these services.
