Participants consisted of two samples of adult heroin-dependent African Americans. The first sample was newly admitted to a health center or a mental health center providing buprenorphine (N = 200), and the second sample was newly admitted to one of two hospital-based methadone programs (N = 178). The Addiction Severity Index (ASI) and the Friends Supplemental Questionnaire were administered at treatment entry and data were analyzed with logistic regression.
BT participants were more likely to be female (p = .017) and less likely to inject (p = .001). Participants with only prior buprenorphine treatment experience were nearly five time more likely to enter buprenorphine than methadone treatment (p < .001). Those with experience with both treatments were more than twice as likely to enter BT (OR = 2.7, 95%CI = 1.11-6.62; p = .028). In the 30 days prior to treatment entry, BT participants reported more days of medical problems (p = .002) and depression (p = .044), and were more likely to endorse a lifetime history of depression (p < .001).
Methadone and buprenorphine treatment provided in the public sector may attract different patient subpopulations. Providing buprenorphine treatment through drug treatment programs co-located with a health and mental health center may have accounted for their higher rates of medical and psychiatric problems and appears to be useful in attracting a diverse group of patients into public-sector funded treatment.
