Overview of 1-year follow-up outcomes in the Drug Abuse Treatment Outcome Study (DATOS).

Abstract

The Drug Abuse Treatment Outcome Study (DATOS) collected 1-year follow-up outcomes for 2,966 clients in outpatient methadone (OMT), long-term residential (LTR), outpatient drug-free (ODF), and short-term inpatient (STI) programs in 1991-1993. LTR, STI, and ODF clients reported 50% less weekly or daily cocaine use in the follow-up year than in the preadmission year. Reductions were greater (p < .01) for clients treated for 3 months or more. Clients still in OMT reported less weekly or daily heroin use than clients who left OMT. Multivariate analysis confirmed that 6 months or more in ODF and LTR and enrollment in OMT were associated with the reductions. Reductions of 50% in illegal activity and 10% increases in full-time employment for LTR clients were related (p < .01) to treatment stays of 6 months or longer. The results replicated findings from 1979-1981 for heroin use in OMT and illegal activity and employment for LTR but not for illegal activity in OMT and ODF.The Drug Abuse Treatment Outcome Study (DATOS) is the third in a series of studies

The adoption of medications in substance abuse treatment: Associations with organizational characteristics and technology clusters

“…This class of medications is highly regulated in the US, with clinics and prescribing physicians facing specific regulatory requirements (Jaffe and O'Keefe, 2003). A large literature has established methadone maintenance (MMT) as an evidence-based treatment for opiate dependence (Hubbard et al, 1997;Mattick et al, 2003;Ward et al, 1999;NIH, 1997). MMT has tended to be concentrated within a treatment sector consisting of opioid treatment programs (OTPs) that exclusively dispense this medication.…”

The Drug Treatment Outcomes Research Study (DTORS): Baseline report

“…NTORS, in addition to other key drug treatment outcome studies, Drug Abuse Treatment Outcome Study (DATOS) (Hubbard et al, 1997), Australian Treatment Outcome Study (ATOS) (Teeson, et al, 2005), and the Drug Outcome Research Study in Scotland (DORIS) (McKeganey, et al, 2006), found signifi cant reductions in both drug use and criminal activity at follow-up. These fi ndings were more prominent for those that had been retained in treatment for three months or more (Hubbard, et al, 1997). The increased government spend on drug treatment in recent years and the widespread introduction of pro-active referral schemes, in particular the Drug Interventions Programme, has introduced greater heterogeneity amongst drug services' clients than that present a decade ago.…”

Characteristics of opiate users presenting for a new treatment episode: Baseline data from the national drug treatment outcome study in Ireland (ROSIE)

“…Recognition of the harms associated with problem drug use, and the chronic nature of this condition, has lead to increased availability of treatment and/or rehabilitative services in Ireland under the National Drug Strategy (2001). Although international studies support the overall effectiveness of established treatment options available for problem drug users (Anglin, Hser, & Grella, 1997;Gossop, Marsden, Stewart, & Kidd, 2003;Hubbard, Craddock, Flynn, Anderson, & Etheridge, 1997;Teesson et al, 2006), to date, no national longitudinal data have been available to determine the effectiveness of such treatment options in the Irish context. Treatment evaluation research has traditionally relied upon outcome studies as a logical first step in understanding effectiveness.…”
