title: Characterizing "nonresponsive" methadone patients.
abstract: A review of records at a large urban methadone clinic revealed a substantial group of patients with treatment tenures of at least 6 months whose urinalysis results indicated continued regular use of opiates. In an attempt to characterize these "nonresponsive" patients and to identify their specific treatment needs, we compared them to a group of patients with comparable treatment tenures but whose urinalysis results indicated little or no recent illicit opiate use. Contrary to expectations, opiate use itself was virtually the only feature that clearly distinguished the two groups. "Responders" and "nonresponders" did not differ significantly on measures of psychosocial problem severity in any other area, nor did they differ in their treatment service utilization. Moreover, examination of admission data indicated that the two groups showed similar rates of improvement in the severity of their psychosocial problems in all seven measured areas. The implications of these results for treatment and clinic administration are discussed.
