title: Clinical differences between opioid abuse classes ameliorated after 1 year of buprenorphine-medication assisted treatment.
abstract: This study compared the clinical and demographic profiles of three opioid-dependent user groups, and measured their response to 1 year of buprenorphine-medication assisted treatment. Opioid prescription, street, and combination (street + prescription) users completed the Addiction Severity Index multiple times over the course of one treatment year. Although groups differed on all measured demographics (P values <.05) and on six of seven Addiction Severity Index composite scores at induction (P values <.05), differences were ameliorated after 1 year. Findings highlight the disparities between the various opioid-dependent patient subpopulations and suggest that buprenorphine-medication assisted treatment is an effective treatment across user subtypes.
