Methadone maintenance in primary care: a randomized controlled trial.

CONTEXT: Methadone maintenance is an effective treatment for opioid dependence, yet its use is restricted to federally licensed narcotic treatment programs (NTPs). Office-based care of stabilized methadone maintenance patients is a promising alternative but no data are available from controlled trials regarding this type of program. OBJECTIVE: To determine the feasibility and efficacy of office-based methadone maintenance by primary care physicians vs in an NTP for stable opioid-dependent patients. DESIGN: Six-month, randomized controlled open clinical trial conducted February 1999-March 2000. SETTING: Offices of 6 primary care internists and an NTP. PATIENTS: Forty-seven opioid-dependent patients who had been receiving methadone maintenance therapy in an NTP without evidence of illicit drug use for 1 year and without significant untreated psychiatric comorbidity were randomized; 1 patient refused to participate after treatment assignment to NTP. INTERVENTIONS: Patients were randomly assigned to receive office-based methadone maintenance from primary care physicians, who received specialized training in the care of opioid-dependent patients (n = 22), or usual care at an NTP (n = 24). MAIN OUTCOME MEASURES: Illicit drug use, clinical instability (persistent drug use), patient and clinician satisfaction, functional status, and use of health, legal, and social services, compared between the 2 groups. RESULTS: Eleven of 22 (50%; 95% confidence interval [CI], 29%-71%) patients in office-based care compared with 9 of 24 (38%; 95% CI, 21%-57%) of NTP patients had a self-report or urine toxicology test result indicating illicit opiate use (P =.39). Hair toxicology testing detected an additional 2 patients in each treatment group with evidence of illicit drug use, but this did not change the overall findings. Ongoing illicit drug use meeting criteria for clinical instability occurred in 4 of 22 (18%; 95% CI, 7%-39%) patients in office-based care compared with 5 of 24 (21%; 95% CI, 9%-41%) NTP patients (P =.82). Sixteen of the 22 (73%; 95% CI, 54%-92%) office-based patients compared with 3 of the 24 (13%; 95% CI, 0%-26%) NTP patients thought the quality of care was excellent (P =.001). There were no differences over time within or between groups in functional status or use of health, legal, or social services. CONCLUSIONS: Our results support the feasibility and efficacy of transferring stable opioid-dependent patients receiving methadone maintenance to primary care physicians' offices for continuing treatment and suggest guidelines for identifying patients and clinical monitoring.

Community reinforcement approach for combined opioid and cocaine dependence. Patterns of engagement in alternate activities.

We compared outcomes for agonist-maintained patients with combined opioid and cocaine dependence who were treated in an earlier clinical trial with group drug counseling (DC; n = 57) or in a current trial with the Community Reinforcement Approach (CRA; n = 60). The association between engagement in nondrug-related activities and abstinence was also evaluated. There were no significant differences between the treatments in retention or drug use. The total number of hours and average hours per week engaged in nondrug-related activities was significantly higher for CRA-treated patients who achieved abstinence from opioids, cocaine, or both combined than for those who never achieved abstinence. Although CRA was not more effective overall than DC, the finding that engagement in reinforcing community activities unrelated to drug use (e.g., planned pleasurable events or parenting activities) was associated with abstinence suggests that the planning and reinforcement of specific nondrug-related social, vocational, and recreational activities is a crucial component of CRA.

Motivational interviewing and treatment adherence among psychiatric and dually diagnosed patients.

The effect of motivational interviewing on outpatient treatment adherence among psychiatric and dually diagnosed inpatients was investigated. Subjects were 121 psychiatric inpatients, 93 (77%) of whom had concomitant substance abuse/dependence disorders, who were randomly assigned to: a) standard treatment (ST), including pharmacotherapy, individual and group psychotherapy, activities therapy, milieu treatment, and discharge planning; or b) ST plus motivational interviewing (ST+MI), which involved 15 minutes of feedback on the results of a motivational assessment early in the hospitalization, and a 1-hour motivational interview just before discharge. Interviewers utilized motivational techniques described in Miller and Rollnick (1991), such as reflective listening, discussion of treatment obstacles, and elicitation of motivational statements. Results indicated that the proportion of patients who attended their first outpatient appointment was significantly higher for the ST+MI group (47%) than for the ST group (21%; chi2 = 8.87, df = 1, p<.01) overall, and for dually diagnosed patients (42% for ST+MI vs. 16% for ST only; chi2 = 7.68, df = 1, p<.01). Therefore, brief motivational interventions show promise in improving outpatient treatment adherence among psychiatric and dually diagnosed patients.

Effectiveness of anxiety management training in the treatment of posttraumatic stress disorder: a preliminary report.

This preliminary study investigated the effectiveness of anxiety management training (AMT), a coping skills treatment similar to systematic desensitization, in comparison to implosive therapy (IT), an exposure-based treatment, for treating six Vietnam combat veterans with posttraumatic stress disorder (PTSD). The Clinician Administered PTSD Interview Scale (CAPS; Blake et al. (1988), The Behaviour Therapist, 18, 187-188) and a self-monitoring measure (Weathers et al., 1991) were used as dependent measures. A single-subject, multiple-baseline, crossover design (ABC/ACB) was employed. A new statistic for such designs (Mueser et al. (1991), Behaviour Modification, 15, 134-155), based on classical test theory, was used to assess treatment effects on intrusive war memories and avoidance of stimuli reminiscent of war. Within-subject results indicated that AMT and IT were similarly effective in reducing the frequency and intensity of intrusions and avoidance. This preliminary report therefore suggests that it may be productive to investigate multidimensional approaches (combining coping skills, exposure-based, and other approaches) to the treatment of combat-related PTSD as Foa et al. (1991), Journal of Consulting and Clinical Psychology, 59, 715-723 and Nishith et al. (1995), Behaviour Therapy, 26, 319-335 have for rape-related PTSD.
