Effective alternatives to long waiting lists for entry into methadone hydrochloride maintenance treatment are needed to reduce the complications of continuing heroin dependence and to increase methadone treatment entry.
                To compare the effectiveness of interim methadone maintenance with that of the usual waiting list condition in facilitating methadone treatment entry and reducing heroin and cocaine use and criminal behavior.
                Randomized, controlled, clinical trial using 2 conditions, with treatment assignment on a 3:2 basis to interim maintenance-waiting list control.
                A methadone treatment program in Baltimore.
                A total of 319 individuals meeting the criteria for current heroin dependence and methadone maintenance treatment.
                Participants were randomly assigned to either interim methadone maintenance, consisting of an individually determined methadone dose and emergency counseling only for up to 120 days, or referral to community-based methadone treatment programs.
                Entry into comprehensive methadone maintenance therapy at 4 months from baseline; self-reported days of heroin use, cocaine use, and criminal behavior; and number of urine drug test results positive for heroin and cocaine at the follow-up interview conducted at time of entry into comprehensive methadone treatment (or at 4 months from baseline for participants who did not enter regular treatment).
                Significantly more participants assigned to the interim methadone maintenance condition entered comprehensive methadone maintenance treatment by the 120th day from baseline (75.9%) than those assigned to the waiting list control condition (20.8%) (P<.001). Overall, in the past 30 days at follow-up, interim participants reported significantly fewer days of heroin use (P<.001), had a significant reduction in heroin-positive drug test results (P<.001), reported spending less money on drugs (P<.001), and received less illegal income (P<.02) than the waiting list participants.
                Interim methadone maintenance results in a substantial increase in the likelihood of entry into comprehensive treatment, and is an effective means of reducing heroin use and criminal behavior among opioid-dependent individuals awaiting entry into a comprehensive methadone treatment program. In a 3 x 2 factorial design, 360 new admissions to methadone maintenance were randomly assigned to one of three levels of counseling: (1) "medication only," (2) "standard" counseling, and (3) "enhanced" services; and one of two contingency contracting conditions: (1) no contingencies (NC), and (2) contingency contracting (CC). Contingency contracting included discharge for continuous positive urines; subsequently CC subjects were discharged at a greater rate than the NC group. However, CC subjects were more likely to be readmitted. NC subjects provided more urines positive for any illicit drug use than did CC subjects. For opiate positives a significant level of counseling by contingency contracting interaction was found with medication only/CC subjects obtaining fewer opiate positives than medication only/NC subjects. The impact of reduced or enhanced services and of contingency contracting will not be fully understood until longer term follow-up (18 and 24 month) is completed. Results suggest that contingency management procedures could be utilized in settings offering minimum services (e.g., "interim methadone") to achieve treatment outcomes similar to programs offering standard counseling services. A controlled trial was conducted evaluating cognitive-behavioural group psychotherapy as a measure to reduce concomitant drug use in methadone maintenance treatment (MMT). 73 opiate addicts were randomly assigned to local routine MMT or to routine MMT plus group psychotherapy (20 sessions over 20 weeks). Psychotherapy was delivered by therapists according to a manual. Drug use (urine screen) was compared at onset of psychotherapy, end of intervention period (6 months after study onset), and 6 months later. Data analysis was done according to intention-to-treat principles. Results indicated that patients in the psychotherapy group (n = 41) showed less drug use than control subjects (n = 32). This group difference was statistically significant at 6-month follow-up (p = 0.02). These findings underscore the usefulness of group psychotherapy in MMT. The delayed effect is comparable to other studies evaluating cognitive-behavioural psychotherapy.
                (c) 2005 S. Karger AG, Basel. This study examined the differential efficacy and relative costs of two intensities of adjunctive psychosocial services--a day treatment program and enhanced standard care--for the treatment of opioid-dependent patients maintained on methadone hydrochloride.
                A 12-week randomized clinical trial with 6-month follow-up was conducted in a community-based methadone maintenance program. Of the 308 patients who met inclusion criteria, 291 began treatment (day treatment program: N=145; enhanced standard care: N=146), and 237 completed treatment (82% of those assigned to the day treatment program and 81% of those receiving enhanced standard care). Two hundred twenty of the patients participated in the 6-month follow-up (75% of those in the day treatment program and 73% of those in enhanced standard care provided a follow-up urine sample for screening). Both interventions were 12 weeks in duration, manual-guided, and provided by master's-level clinicians. The day treatment was an intensive, 25-hour-per-week program. The enhanced standard care was standard methadone maintenance plus a weekly skills training group and referral to on- and off-site services. Outcome measures included twice weekly urine toxicology screens, severity of addiction-related problems, prevalence of HIV risk behaviors, and program costs.
                Although the cost of the day treatment program was significantly higher, there was no significant difference in the two groups' use of either opiates or cocaine. Over the course of treatment, drug use, drug-related problems, and HIV risk behaviors decreased significantly for patients assigned to both treatment intensities. Improvements were maintained at follow-up.
                Providing an intensive day treatment program to unemployed, inner-city methadone patients was not cost-effective relative to a program of enhanced methadone maintenance services, which produced comparable outcomes at less than half the cost. To compare changes in HIV risk behaviors between street-recruited opiate injectors who entered and remained in methadone maintenance treatment and those who did not.
                Three hundred sixteen participants were interviewed at baseline, received outreach interventions, and were interviewed again 6 months later.
                Significant (p <.001) reductions in HIV-related risk behaviors, including frequency of injecting, injecting with used (dirty) needles, and sharing injection paraphernalia, were demonstrated. Participants (31%) who entered and remained in methadone maintenance treatment for at least 90 days before follow-up showed a significantly greater reduction in heroin injections than those who did not. They did not show a greater reduction in using dirty needles or sharing other injection paraphernalia.
                These findings suggest that although methadone maintenance may reduce injection frequency, it does not reduce other HIV-related risk behaviors above and beyond what can be accomplished through outreach interventions. Treatment facilities and outreach intervention programs should collaborate to provide a comprehensive approach to reducing HIV risk behaviors among drug injectors both in and out of drug treatment. The authors tested the efficacy of individual psychotherapy in the rehabilitation counseling of psychiatrically symptomatic opiate-dependent patients during methadone maintenance treatment in community programs.
                Volunteers in three community programs were randomly assigned to 24 weeks of counseling plus supplemental drug counseling or to counseling plus supportive-expressive psychotherapy. Follow-ups were done 1 and 6 months after treatment ended. A total of 84 subjects were evaluated at both follow-up points.
                During the study the patients receiving supportive-expressive psychotherapy and those receiving drug counseling had similar proportions of opiate-positive urine samples, but the patients receiving supportive-expressive psychotherapy had fewer cocaine-positive urine samples and required lower doses of methadone. One month after the extra therapy ended both groups had made significant gains, but there were no significant differences between groups. By 6-month follow-up many of the gains made by the drug counseling patients had diminished, whereas most of the gains made by the patients who received supportive-expressive psychotherapy remained or were still evident; many significant differences emerged, all favoring supportive-expressive psychotherapy.
                Psychotherapy can be delivered to psychiatrically impaired patients in community methadone programs. Additional counseling is associated with early benefits comparable to those from psychotherapy, but these gains are not sustained. The gains associated with psychotherapy persist and in some cases strengthen for at least 6 months after the end of therapy. Contingency management interventions that provide tangible incentives based on objective indicators of drug abstinence have improved treatment outcomes of substance abusers, but have not been widely implemented in community drug abuse treatment settings.
                To compare outcomes achieved when a lower-cost prize-based contingency management treatment is added to usual care in community methadone hydrochloride maintenance treatment settings.
                Random assignment to usual care with (n = 198) or without (n = 190) abstinence incentives during a 12-week trial.
                Six community-based methadone maintenance drug abuse treatment clinics in locations across the United States.
                Three hundred eighty-eight stimulant-abusing patients enrolled in methadone maintenance programs for at least 1 month and no more than 3 years.
                Participants submitting stimulant- and alcohol-negative samples earned draws for a chance to win prizes; the number of draws earned increased with continuous abstinence time.
                Total number of stimulant- and alcohol-negative samples provided, percentage of stimulant- and alcohol-negative samples provided, longest duration of abstinence, retention, and counseling attendance.
                Submission of stimulant- and alcohol-negative samples was twice as likely for incentive as for usual care group participants (odds ratio, 1.98; 95% confidence interval, 1.42-2.77). Achieving 4 or more, 8 or more, and 12 weeks of continuous abstinence was approximately 3, 9, and 11 times more likely, respectively, for incentive vs usual care participants. Groups did not differ on study retention or counseling attendance. The average cost of prizes was 120 dollars per participant.
                An abstinence incentive approach that paid 120 dollars in prizes per participant effectively increased stimulant abstinence in community-based methadone maintenance treatment clinics. This study compared 2 psychosocial approaches for the treatment of cocaine dependence: contingency management (CM) and cognitive-behavioral therapy (CBT).
                Patients with cocaine dependence who were receiving methadone maintenance treatment (n = 120) were randomly assigned to 1 of 4 conditions: CM, CBT, combined CM and CBT (CBT + CM), or treatment as usual (ie, methadone maintenance treatment program only [MMTP only]) (n = 30 per cell). The CM procedures and CBT materials were comparable to those used in previously published research. The active study period was 16 weeks, requiring 3 clinic visits per week. Participants were evaluated during treatment and at 17, 26, and 52 weeks after admission.
                Urinalysis results during the 16-week treatment period show that participants assigned to the 2 groups featuring CM had significantly superior in-treatment urinalysis results, whereas urinalysis results from participants in the CBT group were not significantly different than those from the MMTP-only group. At week 17, self-reported days of cocaine use were significantly reduced from baseline levels for all 3 treatment groups but not for the MMTP-only group. At the 26-week and 52-week follow-up points, CBT participants showed substantial improvement, resulting in equivalent performance with the CM groups as indicated by both urinalysis and self-reported cocaine use data.
                Study findings provide solid evidence of efficacy for CM and CBT. Although the effect of CM is significantly greater during treatment, CBT appears to produce comparable long-term outcomes. There was no evidence of an additive effect for the 2 treatments in the CM + CBT group. To assess the feasibility of a randomized clinical trial of supervised injectable versus oral methadone maintenance and to assess medium-term treatment outcomes.
                Randomized clinical trial of supervised injectable versus supervised oral methadone maintenance treatment (MMT). Trial participants were dependent illicit opiate injectors allocated at intake to supervised injectable or oral methadone maintenance treatment.
                Specialist addictions treatment centre in South London.
                Forty dependent illicit opiate injectors seeking methadone maintenance treatment.
                Daily supervised injectable and oral methadone maintenance, delivered at the treatment centre.
                Frequency of illicit heroin use and frequency of illicit drug injecting during 30 days before intake to treatment and prior to 6-month follow-up. Secondary outcome measures: frequency of use of illicit methadone, crack cocaine, benzodiazepines and alcohol, physical and psychological health symptoms and acquisitive crime.
                Injectable and oral MMT were both generally acceptable to the study participants: there was a high level of agreement to enter the randomized trial, and subsequent retention in treatment was good. The average number of days of illicit heroin use reduced from 22.2 to 7.6 for the injectable MMT group and from 22.4 to 8.7 for the oral MMT group. The average number of days of illicit injecting reduced from 25.7 to 10.8 days for the injectable group and from 20.1 to 11.9 days for the oral group. Patients' physical and psychological health symptoms and involvement in acquisitive crime also reduced in both groups. Treatment satisfaction ratings at follow-up were higher among patients in the injectable MMT group. The ratio for the actual medication costs between injectable and oral MMT was 6.8:1, and for the direct operational costs was 4.7:1. There was some evidence of a differential patient response with greater reductions in heroin use occurring among patients who were daily illicit injectors and had poorer psychological and physical health (at entry) who were allocated to injectable MMT.
                Conduct of the trial has demonstrated that it is feasible to implement supervised injectable methadone maintenance treatment in the context of (although separate from) a specialist oral methadone maintenance service. Patients assigned to receive either supervised injectable or oral MMT had broadly equivalent, positive during-treatment outcomes at 6-month follow-up. Future studies should seek to identify patient characteristics which are linked to good outcome in injectable MMT. Practical evidence-based guidance to physicians about determining which patients are more suitable for injectable MMT is urgently needed. This paper provides a detailed analysis of the 2-year outcomes for 351 drug misusers allocated on an intention-to-treat basis to methadone maintenance or methadone reduction treatments. Both groups showed substantial reductions in their use of illicit drugs and in other outcome areas. However, whereas most methadone maintenance patients received maintenance, only about one third of those allocated to methadone reduction received methadone reduction, and many actually received a form of methadone maintenance. Reduction patients were more likely to receive low doses of methadone, and were less likely to remain in treatment. For maintenance patients, higher doses and retention in treatment were both associated with improvements in illicit heroin use at 2 years. For the reduction patients, the more rapidly the methadone was reduced, the worse the heroin use outcomes. For patients in both treatment conditions, reductions in heroin use were associated with improvements in other outcome areas. The more severely dependent patients showed better outcomes in methadone maintenance. Methadone reduction treatment processes were associated with poor outcomes, and many patients who were allocated to methadone reduction treatment did not receive reduction treatment as intended. This calls into question the appropriateness of either the initial treatment planning process or the treatment delivery process, or both. A clearer distinction should be made between methadone maintenance and methadone reduction. Treatment goals should be made explicit both to the patient and to the clinical staff at the start of treatment. We suggest the need for a reappraisal of the goals and procedures of methadone reduction treatment. Despite evidence that methadone maintenance treatment (MMT) is effective for opioid dependence, it remains a controversial therapy because of its indefinite provision of a dependence-producing medication.
                To compare outcomes of patients with opioid dependence treated with MMT vs an alternative treatment, psychosocially enriched 180-day methadone-assisted detoxification.
                Randomized controlled trial conducted from May 1995 to April 1999.
                Research clinic in an established drug treatment service.
                Of 858 volunteers screened, 179 adults with diagnosed opioid dependence were randomized into the study; 154 completed 12 weeks of follow-up.
                Patients were randomized to MMT (n = 91), which required 2 hours of psychosocial therapy per week during the first 6 months; or detoxification (n = 88), which required 3 hours of psychosocial therapy per week, 14 education sessions, and 1 hour of cocaine group therapy, if appropriate, for 6 months, and 6 months of (nonmethadone) aftercare services.
                Treatment retention, heroin and cocaine abstinence (by self-report and monthly urinalysis), human immunodeficiency virus (HIV) risk behaviors (Risk of AIDS Behavior scale score), and function in 5 problem areas: employment, family, psychiatric, legal, and alcohol use (Addiction Severity Index), compared by intervention group.
                Methadone maintenance therapy resulted in greater treatment retention (median, 438.5 vs 174.0 days) and lower heroin use rates than did detoxification. Cocaine use was more closely related to study dropout in detoxification than in MMT. Methadone maintenance therapy resulted in a lower rate of drug-related (mean [SD] at 12 months, 2.17 [3.88] vs 3.73 [6.86]) but not sex-related HIV risk behaviors and in a lower severity score for legal status (mean [SD] at 12 months, 0.05 [0.13] vs 0.13 [0.19]). There were no differences between groups in employment or family functioning or alcohol use. In both groups, monthly heroin use rates were 50% or greater, but days of use per month dropped markedly from baseline.
                Our results confirm the usefulness of MMT in reducing heroin use and HIV risk behaviors. Illicit opioid use continued in both groups, but frequency was reduced. Results do not provide support for diverting resources from MMT into long-term detoxification. To determine whether making patient-reported cancer needs, quality-of-life (QOL), and psychosocial information available to the health care team, allowing coordinated specifically targeted psychosocial interventions, resulted in reduced cancer needs, improved QOL, and increased satisfaction with care received.
                Self-reported cancer needs, QOL, and psychosocial information was collected from 450 people with cancer, using standardized questionnaires via a touch-screen computer. For a randomly chosen two thirds, this information was made available to the health care team who coordinated targeted psychosocial interventions. Information from the remaining one third was not seen. Patients were assessed 2 and 6 months after randomization for changes in their cancer needs, QOL, and psychosocial functioning and satisfaction with overall care received.
                There were no significant differences between the two arms with respect to changes in cancer needs, QOL, or psychosocial functioning between the baseline and follow-up assessments, nor with respect to satisfaction with care. However, for the subgroup of patients who were moderately or severely depressed at baseline, there was a significant reduction in depression for the intervention arm relative to the control arm at the 6-month assessment (P =.001).
                Making patient-reported cancer needs, QOL, and psychosocial data available to the health care team at a single consultation together with coordinated psychosocial interventions does not seem to reduce cancer needs nor improve QOL, psychosocial functioning, or satisfaction with the care received. However, identification of patients with moderate or severe levels of depression may be valuable in reducing subsequent levels of depression. Physicians may prescribe buprenorphine for opioid agonist maintenance treatment outside of narcotic treatment programs, but treatment guidelines for patients with co-occurring cocaine and opioid dependence are not available. This study compares effects of buprenorphine and methadone and evaluates the efficacy of combining contingency management with maintenance treatment for patients with co-occurring cocaine and opioid dependence.
                Subjects with cocaine and opioid dependence (N=162) were provided manual-guided counseling and randomly assigned in a double-blind design to receive daily sublingual buprenorphine (12-16 mg) or methadone (65-85 mg p.o.) and to contingency management or performance feedback. Contingency management subjects received monetary vouchers for opioid- and cocaine-negative urine tests, which were conducted three times a week; voucher value escalated during the first 12 weeks for consecutive drug-free tests and was reduced to a nominal value in weeks 13-24. Performance feedback subjects received slips of paper indicating the urine test results. The primary outcome measures were the maximum number of consecutive weeks abstinent from illicit opioids and cocaine and the proportion of drug-free tests. Analytic models included two-by-two analysis of variance and mixed-model repeated-measures analysis of variance.
                Methadone-treated subjects remained in treatment significantly longer and achieved significantly longer periods of sustained abstinence and a greater proportion drug-free tests, compared with subjects who received buprenorphine. Subjects receiving contingency management achieved significantly longer periods of abstinence and a greater proportion drug-free tests during the period of escalating voucher value, compared with those who received performance feedback, but there were no significant differences between groups in these variables during the entire 24-week study.
                Methadone may be superior to buprenorphine for maintenance treatment of patients with co-occurring cocaine and opioid dependence. Combining methadone or buprenorphine with contingency management may improve treatment outcome. Thirty-four drug addicts, aged 20 - 24 years, with a history of 4 - 8 years of intravenous heroin abuse, were randomly assigned either to a methadone maintenance treatment (MMT) (17) or to an untreated group (17). The untreated controls could not apply for entrance to the program until two years later. It was found that after two years 12 MMT patients had abandoned their drug habits and begun work, whereas 5 had recurrent drug abuse problems. Of the controls, one was drug-free and gainfully employed, 12 were continuously abusing heroin (3 of these had incurred potentially fatal diseases in consequence), 2 were in prison and 2 had diet. Two to seven years after their first visit to the Psychiatric Research Center 8 of the original control group have been accepted into the program. At present 19 (out of 25 admitted) are gainfully employed and no longer abusing drugs. Among the remaining controls 4 are dead, 3 are in prison, one in spite of a serious heart condition abuses heroin and one is drug-free. The rehabilitation rate was thus 76 per cent in the program as compared to 6 per cent among the control group. In addition, MMT obviously reduced the high morbidity and mortality rates found in a selection of heroin addicts who fulfilled the admittance criteria of the Swedish program. This study compared the efficacy of 2 approaches for the treatment of cocaine dependence among methadone-maintained patients with and without antisocial personality disorder (ASPD). Patients were randomly assigned to 4 study conditions: cognitive-behavioral treatment (CBT), contingency management (CM), CBT with CM, or methadone maintenance. The Structural Clinical Interview for Mental Disorders-IV was administered to 108 patients to assess ASPD. A 2-way analysis of variance showed that patients with ASPD were more likely to abstain from cocaine use during treatment than patients without ASPD. The strong treatment effect for ASPD patients was primarily due to the CM condition. Regression analyses showed that ASPD remained significantly related to CM treatment responsivity while controlling for other factors. To test whether a combination of contingency management and methadone dose increase would promote abstinence from heroin and cocaine, we conducted a randomized controlled trial using a 2 x 3 (dosexcontingency) factorial design in which dose assignment was double-blind. Participants were 252 heroin- and cocaine-abusing outpatients on methadone maintenance. They were randomly assigned to methadone dose (70 or 100mg/day, double-blind) and voucher condition (noncontingent, contingent on cocaine-negative urines, or "split"). The "split" contingency was a novel contingency that reinforced abstinence from either drug while doubly reinforcing simultaneous abstinence from both: the total value of incentives was "split" between drugs to contain costs. The main outcome measures were percentages of urine specimens negative for heroin, cocaine, and both simultaneously; these were monitored during a 5-week baseline of standard treatment (to determine study eligibility), a 12-week intervention, and a 10-week maintenance phase (to examine intervention effects in return-to-baseline conditions). DSM-IV criteria for ongoing drug dependence were assessed at study exit. Urine-screen results showed that the methadone dose increase reduced heroin use but not cocaine use. The split 100mg group was the only group to achieve a longer duration of simultaneous negatives than its same-dose noncontingent control group. The frequency of DSM-IV opiate and cocaine dependence diagnoses decreased in the active intervention groups. For a split contingency to promote simultaneous abstinence from cocaine and heroin, a relatively high dose of methadone appears necessary but not sufficient; an increase in overall incentive amount may also be required. We examined the effectiveness of a contingency management program in preventing relapse to illicit opiate use and increasing treatment retention during outpatient methadone detoxification treatment. Twenty male opiate addicts were randomly assigned to an experimental or control group. Following a 3-week methadone stabilization period, men in both groups received identical gradual methadone dose reductions during Weeks 4 through 9 and were maintained on placebo during Weeks 10 through 13. Beginning in Week 4, control patients received $5.00 for providing a specimen twice weekly. Experimental patients received $10.00 and a take home methadone dose for each opiate-free urine specimen but forfeited the incentives and participated in more intensive clinic procedures when specimens were opiate positive. The contingency management procedure slowed the rate of relapse to illicit opiate use. Experimental patients provided significantly more opiate-free urines during the methadone dose reduction in Weeks 4 through 9 than control patients, although the difference between groups was no longer significant during placebo administration in Weeks 10 through 13. In addition, the contingency management program improved treatment retention and reduced symptom complaints during the detoxification. The usefulness and limitations of contingency management procedures for outpatient methadone detoxification are discussed. Despite its effectiveness, methadone maintenance is rarely provided in American correctional facilities. This study is the first randomized clinical trial in the US to examine the effectiveness of methadone maintenance treatment provided to prisoners with pre-incarceration heroin addiction.
                A three-group randomized controlled trial was conducted between September 2003 and June 2005. Two hundred eleven Baltimore pre-release inmates who were heroin dependent during the year prior to incarceration were enrolled in this study. Participants were randomly assigned to the following: counseling only: counseling in prison, with passive referral to treatment upon release (n=70); counseling+transfer: counseling in prison with transfer to methadone maintenance treatment upon release (n=70); and counseling+methadone: methadone maintenance and counseling in prison, continued in a community-based methadone maintenance program upon release (n=71).
                Two hundred participants were located for follow-up interviews and included in the current analysis. The percentages of participants in each condition that entered community-based treatment were, respectively, counseling only 7.8%, counseling+transfer 50.0%, and counseling+methadone 68.6%, p<.05. All pairwise comparisons were statistically significant (all ps<.05). The percentage of participants in each condition that tested positive for opioids at 1-month post-release were, respectively, counseling only 62.9%, counseling+transfer 41.0%, and counseling+methadone 27.6%, p<.05, with the counseling only group significantly more likely to test positive than the counseling+methadone group.
                Methadone maintenance initiated prior to or immediately after release from prison appears to have beneficial short-term impact on community treatment entry and heroin use. This intervention may be able to fill an urgent treatment need for prisoners with heroin addiction histories. Methadone maintenance programs (MMP) have the potential to play an important role in reducing HIV risk, given the appropriate type and level of ancillary treatments. In this study, we investigated the efficacy of a 12-session harm reduction group intervention for injection drug users, based upon the Information-Motivation-Behavioral skills model of behavior change, that focused on reducing both drug and sex risk. Two hundred and twenty patients entering an MMP were randomized to receive either standard care (SC)-2 hours of counseling per month and a single-session risk reduction intervention-or SC plus the harm reduction group (HRG). Results showed that during treatment, patients receiving HRG were more likely to be abstinent from cocaine and to report fewer unsafe sexual practices. Post-treatment, HRG patients scored higher on a sexual risk quiz and reported increased self-efficacy in high risk sexual situations. Enhancing methadone maintenance with a weekly harm reduction group treatment was somewhat more expensive but can bring about positive changes in behaviors and attitudes that are associated with the transmission of HIV. A clinical trial was used to evaluate short-term interpersonal psychotherapy (IPT) as treatment for psychiatric disorders in opiate addicts who were also participating in a full-service methadone hydrochloride maintenance program. Seventy-two opiate addicts were randomly assigned to one of two treatment conditions for six months: (1) IPT, consisting of weekly individual psychotherapy, and (2) low-contact treatment, consisting of one brief meeting per month. Recruitment was a problem, as only 5% of eligible clients agreed to participate and only around half of the subjects completed the study treatment. The outcome was similar for the two study groups. However, in many of the outcome areas, subjects in both treatment conditions attained significant clinical improvement. Several factors limited the generalizability of findings and may have biased against showing a psychotherapy effect. Positive monetary contingencies for treating opioid dependence complicated by other drug use were examined. Participants (N = 102) entered 6-month methadone transition treatment (MTT) and were randomized into experimental conditions: 51 entered MTT with contingency contracts using monetary reinforcers and targeting abstinence from illicit drug and alcohol use, and 51 entered MTT without contingency contracts targeting abstinence. Outcomes were evaluated by random urinalysis and breath analysis. After 4 months of treatment, individuals in the contingency condition had longer periods of continuous abstinence (p<.005) and more drug-free tests overall (p<.04). Effects were limited, however, to the contracting period. The authors conclude that contingency contracting using monetary reinforcers may be a useful adjunct for achieving abstinence from multiple drugs of abuse during MTT. Important questions remain regarding the necessary duration and intensity for methadone treatment to be effective.
                As part of a clinical trial of tuberculosis chemoprophylaxis [Batki, S.L., Gruber, V.A., Bradley, J.M., Bradley, M., Delucchi, K., 2002. A controlled trial of methadone treatment combined with directly observed isoniazid for tuberculosis prevention in injection drug users. Drug Alcohol Depend. 66 283-293. doi:10.1016/S0376-8716(01)00208-3], patients with opioid dependence were recruited from an outpatient 21-day methadone detoxification program and were randomly assigned to one of three treatment conditions: (1) continuation in 21-day methadone detoxification; (2) transfer to 6-month methadone maintenance with only minimal counseling; or (3) transfer to 6-month methadone maintenance with standard twice monthly counseling and as-needed social work and psychiatric services. Both the 6-month maintenance treatments were followed by 1.5 months of detoxification. Urine drug tests and self-report measures were collected at baseline, months 1-6, and month 8.5.
                Compared to 21-day methadone detoxification, 6-month methadone maintenance with either minimal or standard counseling resulted in fewer opiate positive urine tests and days of self-reported heroin and alcohol use. There was no change in cocaine use or other outcome measures. The increased counseling available in the standard counseling condition did not appear to reduce heroin use further than the minimal counseling condition, in contrast to the effect found for more structured counseling in long-term methadone maintenance (McLellan et al., 1993).
                Six months of methadone maintenance, even with minimal counseling, reduces heroin and alcohol use more than 21-day methadone detoxification. To evaluate relapse prevention (relapse prevention) and contingency management (contingency management) for optimizing smoking cessation outcomes using nicotine replacement therapy for methadone-maintained tobacco smokers.
                Experimental, 2 (relapse prevention)x2 (contingency management) repeated measures design using a platform of nicotine replacement therapy featuring a 2-week baseline period, followed by randomization to 12 weeks of treatment, and 6- and 12-month follow-up visits.
                Three narcotic treatment centers in Los Angeles.
                One hundred and seventy-five participants who met all inclusion and no exclusion criteria.
                Participants received 12 weeks of nicotine replacement therapy and assignment to one of four conditions: patch-only, relapse prevention + patch, contingency management + patch and relapse prevention + contingency management + patch.
                Thrice weekly samples of breath (analyzed for carbon monoxide) and urine (analyzed for metabolites of opiates and cocaine) and weekly self-reported numbers of cigarettes smoked.
                Participants (73.1%) completed 12 weeks of treatment. During treatment, those assigned to receive contingency management showed statistically higher rates of smoking abstinence than those not assigned to receive contingencies (F3,4680=6.3, P=0.0003), with no similar effect observed for relapse prevention. At follow-up evaluations, there were no significant differences between conditions. Participants provided more opiate and cocaine-free urines during weeks when they met criteria for smoking abstinence than during weeks when they did not meet these criteria (F1,2054=14.38, P=0.0002; F1,2419=16.52, P<0.0001).
                Contingency management optimized outcomes using nicotine replacement therapy for reducing cigarette smoking during treatment for opiate dependence, although long-term effects are not generally maintained. Findings document strong associations between reductions in cigarette smoking and reductions in illicit substance use during treatment. This article presents the outcomes of an innovative vocational rehabilitation model designed for methadone-maintained patients -- the Customized Employment Supports (CES) model. CES counselors work intensively with a small caseload of patients to overcome the vocational as well as non-vocational barriers that hinder employment, with the goal of attaining rapid job placement. A randomized clinical trial was implemented at two methadone treatment programs in New York City and was funded by the National Institute on Drug Abuse The study tested the hypothesis that patients assigned to the experimental (CES) condition would have better employment outcomes than those assigned to a control condition who received standard vocational counseling at the programs. The data were collected from May 2001 through April 2005. The efficacy sample for the analysis consisted of 168 patients who completed follow-up interviews. The sample was 58% male, 75% minority group, average age 45 years, and in methadone treatment for an average of five years. The results supported the hypothesis for two measures of employment; i.e., the CES group was significantly more likely than the control group to obtain both any paid employment and informal paid employment. However, there were no significant differences for competitive employment or total earnings. The study's limitations are noted. Implications of the findings for the improvement of vocational rehabilitation for addiction patients are discussed. To evaluate an experimental heroin maintenance programme. Design: Randomised trial.
                Outpatient clinic in Geneva, Switzerland.
                Heroin addicts recruited from the community who were socially marginalised and in poor health and had failed in at least two previous drug treatments.
                Patients in the experimental programme (n=27) received intravenous heroin and other health and psychosocial services. Control patients (n=24) received any other conventional drug treatment (usually methadone maintenance). Main outcome measures: Self reported drug use, health status (SF-36), and social functioning.
                25 experimental patients completed 6 months in the programme, receiving a median of 480 mg of heroin daily. One experimental subject and 10 control subjects still used street heroin daily at follow up (difference 44%; 95% confidence interval 16% to 71%). Health status scores that improved significantly more in experimental subjects were mental health (0.58 SD; 0.07 to 1.10), role limitations due to emotional problems (0.95 SD; 0.11 to 1.79), and social functioning (0.65 SD; 0.03 to 1.26). Experimental subjects also significantly reduced their illegal income and drug expenses and committed fewer drug and property related offences. There were no benefits in terms of work, housing situation, somatic health status, and use of other drugs. Unexpectedly, only nine (38%) control subjects entered the heroin maintenance programme at follow up.
                A heroin maintenance programme is a feasible and clinically effective treatment for heroin users who fail in conventional drug treatment programmes. Even in this population, however, another attempt at methadone maintenance may be successful and help the patient to stop using injectable opioids. The Los Angeles Enhanced Methadone Maintenance Project was a 5-year research demonstration project funded by the National Institute on Drug Abuse with the goal of reducing high-risk behavior for human immunodeficiency virus (HIV) among heroin users. A clinic was established for the purposes of the study and 500 clients with high-risk profiles were recruited into treatment. Follow-up assessments demonstrated that clients had reduced their drug use, criminal behavior, and HIV-risk behaviors after entering treatment. At the end of the project clients were given the option of continuing treatment at the clinic on a fee-for-service basis, transferring to another treatment provider, or undergoing detoxification. Clients who were eligible for Medicaid were likely to continue receiving methadone treatment, but those without Medicaid funding were not. The implications of terminating treatment among a high-risk population recruited into a research demonstration project are discussed. The aim was to determine whether methadone maintenance treatment reduced heroin use, syringe sharing and HIV or hepatitis C incidence among prisoners.
                All eligible prisoners seeking drug treatment were randomised to methadone or a waitlist control group from 1997 to 1998 and followed up after 4 months. Heroin use was measured by hair analysis and self report; drugs used and injected and syringe sharing were measured by self report. Hepatitis C and HIV incidence was measured by serology.
                Of 593 eligible prisoners, 382 (64%) were randomised to MMT (n=191) or control (n=191). 129 treated and 124 control subjects were followed up at 5 months. Heroin use was significantly lower among treated than control subjects at follow up. Treated subjects reported lower levels of drug injection and syringe sharing at follow up. There was no difference in HIV or hepatitis C incidence.
                Consideration should be given to the introduction of prison methadone programs particular where community based programs exist. Retention in a Methadone Maintenance Treatment Program (MMTP) is predictive of abstaining from heroin and has other benefits. Many individuals leave treatment before they experience these positive outcomes.
                This research project targeted MMTP drop-outs with an intervention designed to assist them in returning to drug treatment.
                Subjects who had left MMTP within the prior 12 months were randomly assigned to intervention or comparison groups. The 3-month long intervention consisted of street outreach, cognitive behavioral groups, and individual counseling. Data were analyzed for 175 subjects who were out of treatment at baseline and who returned for a 6-month follow-up interview (Intervention group, N=111; Comparison group, N=64).
                A total of 87% of subjects assigned to the intervention condition participated in at least one component. Intervention subjects who attended two or more cognitive behavioral group sessions were more likely than those who attended 0-1 sessions or those in the comparison group to have returned to treatment during the 6 month follow up time period (72 vs. 53 vs. 50%, respectively, P<0.05, chi square test).
                MMTP drop-outs need not be lost to the drug treatment system if special efforts are made to engage them in interventions developed to encourage treatment re-entry. Pregnant injecting drug users were randomly assigned to: (i) individually receive a six-session cognitive-behavioural intervention in addition to their usual methadone maintenance treatment (intervention condition (I) (n = 40)); or (ii) their usual methadone maintenance treatment only (control condition (C) (n = 40)). There was no change in drug use per se in either group after the intervention. However, at 9-month follow-up the I group had significantly reduced some HIV risk-taking behaviours (in particular injecting risk behaviours). The I group reduced the needle risk associated both with "typical" use (drug use in the month before interview) and "binge" use (drug use in the month nominated as the heaviest month of drug use in the previous 6 months). The intervention had no effect on sexual risk behaviours. The finding of reduced injecting risk behaviour following the six-session intervention suggests that such an intervention may be of benefit for individuals persisting with injecting risk behaviours despite methadone maintenance treatment and the availability of sterile injection equipment. A study was undertaken to investigate the influence of methadone prescribers' commitment to abstinence-oriented policies on retention in their maintenance programs. Two hundred and eighty patients recently enrolled in single-person, private methadone programs were interviewed and followed for 8 years. The prescribing physicians' scores on an Abstinence Orientation Scale, derived from an independent sample of methadone program staff, were significantly associated with their patients' risk of premature discharge. The influence of program orientation on retention was greater the higher the maximum dose of methadone. More attention should be paid to the effect of staff attitudes and beliefs on the effectiveness of maintenance treatment.
For the considered outcomes, it seems that adding any psychosocial support to standard maintenance treatments do not add additional benefits. Data do not show differences also for contingency approaches, contrary to all expectations. Duration of the studies was too short to analyse relevant outcomes such as mortality. It should be noted that the control intervention used in the studies included in the review on maintenance treatments, is a program that routinely offers counselling sessions in addition to methadone; thus the review, actually, did not evaluate the question of whether any ancillary psychosocial intervention is needed when methadone maintenance is provided, but the narrower question of whether a specific more structured intervention provides any additional benefit to a standard psychosocial support. These interventions probably can be measured and evaluated by employing diverse criteria for evaluating treatment outcomes, aimed to rigorously assess changes in emotional, interpersonal, vocational and physical health areas of life functioning.
