Injection drug users' experience with and attitudes toward methadone clinics in Denver, CO.

Clients' perceptions and attitudes toward methadone treatment programs are frequently overlooked in substance abuse research. Given the importance of methadone maintenance as a harm-reduction strategy and clients' concerns about treatment, it is essential to understand perceptions and attitudes toward existing programs. Using data from the 2009 National HIV Behavioral Surveillance system with injection drug users in Denver, CO, we evaluated participants' experiences with methadone clinics and examined predictive factors associated with ever being a client of a methadone clinic. Costs of services, perceptions of staff not caring about the client, and attitudes toward the counseling services seemed to be the major barriers to program retention. Besides heroin use, previous attempt at self-detoxification and being infected with hepatitis C were the strongest predictors of ever being on methadone treatment. Addressing the barriers to program retention and encouraging treatment engagement are essential to embracing methadone maintenance as a harm-reduction strategy for injection drug users.
