Benzodiazepine Use and Misuse Among Patients in a Methadone Program

BackgroundBenzodiazepines (BZD) misuse is a serious public health problem, especially among opiate-dependent patients with anxiety enrolled in methadone program because it puts patients at higher risk of life-threatening multiple drug overdoses. Both elevated anxiety and BZD misuse increase the risk for ex-addicts to relapse. However, there is no recent study to assess how serious the problem is and what factors are associated with BZD misuse. This study estimates the prevalence of BZD misuse in a methadone program, and provides information on the characteristics of BZD users compared to non-users.MethodsAn anonymous survey was carried out at a methadone program in Baltimore, MD, and all patients were invited to participate through group meetings and fliers around the clinic on a voluntary basis. Of the 205 returned questionnaires, 194 were complete and entered into final data analysis. Those who completed the questionnaire were offered a

Randomized Trial of Standard Methadone Treatment Compared to Initiating Methadone without Counseling: 12-month Findings

5 gift card as an appreciation.Results47% of the respondents had a history of BZD use, and 39.8% used BZD without a prescription. Half of the BZD users (54%) started using BZD after entering the methadone program, and 61% of previous BZD users reported increased or resumed use after entering methadone program. Compared to the non-users, BZD users were more likely to be White, have prescribed medication for mental problems, have preexistent anxiety problems before opiate use, and had anxiety problems before entering methadone program. They reported more mental health problems in the past month, and had higher scores in anxiety state, depression and perceived stress (p < .05).ConclusionsImportant information on epidemiology of BZD misuse among methadone-maintenance patients suggests that most methadone programs do not address co-occurring anxiety problems, and methadone treatment may trigger onset or worsening of BZD misuse. Further study is needed to explore how to curb misuse and abuse of BZD in the addiction population, and provide effective treatments targeting simultaneously addiction symptoms, anxiety disorders and BZD misuse.

Geriatric patients on a substance abuse consultation service.

AIMS This study aimed to determine the relative effectiveness of 12 months of interim methadone (IM; supervised methadone with emergency counseling only for the first 4 months of treatment), standard methadone treatment (SM; with routine counseling) and restored methadone treatment (RM: routine counseling with smaller case-loads). DESIGN A randomized controlled trial was conducted comparing IM, SM and RM treatment. IM lasted for 4 months, after which participants were transferred to SM. SETTING The study was conducted in two methadone treatment programs in Baltimore, MD, USA. PARTICIPANTS The study included 230 adult methadone patients newly admitted through waiting-lists. MEASUREMENTS We administered the Addiction Severity Index and a supplemental questionnaire at baseline, 4 and 12 months post- baseline. Measurements included retention in treatment, self-reported days of heroin and cocaine use, criminal behavior and arrests and urine tests for heroin and cocaine metabolites. FINDINGS At 12 months, on an intent-to-treat basis, there were no significant differences in retention in treatment among the IM, SM and RM groups (60.6%, 54.8% and 37.0%, respectively). Positive urine tests for the three groups declined significantly from baseline (Ps < 0.001 and 0.003, for heroin and cocaine metabolites, respectively) but there were no significant group x time interactions for these measures. At least one arrest was reported by 30.6% of the sample during the year, but there were no significant between-group effects. CONCLUSIONS Limited availability of drug counseling services should not be a barrier to providing supervised methadone to adults dependent on heroin--at least for the first 4 months of treatment.

Brief vs. extended buprenorphine detoxification in a community treatment program: engagement and short-term outcomes.

The authors describe the demographic and substance use characteristics of older adults (N=310) evaluated by a hospital-based substance abuse consultation service during a 6-year period and compares them to younger adults evaluated by the service. Older adults were more likely to use alcohol and less likely to be injection drug users and heroin, cocaine, or polysubstance users. Elderly patients were also more likely to be admitted for cardiac or gastrointestinal conditions and less likely to be admitted for infections. We estimated that only 1% of older adults admitted to the hospital were referred for substance abuse consultations. Our results suggest that substance use disorders in elderly patients are underdiagnosed and undertreated in the hospital setting.

Transitioning Opioid-Dependent Patients from Detoxification to Long-term Treatment: Efficacy of Intensive Role Induction

Background: Despite evidence supporting the efficacy of buprenorphine relative to established detoxification agents such as clonidine, little research has examined: 1) how best to implement buprenorphine detoxification in outpatient settings; and 2) whether extending the length of buprenorphine detoxification improves treatment engagement and outcomes. Objectives: The current study examined the impact on 1) successful detoxification completion; 2) transition to longer-term treatment; and 3) treatment engagement of two different length opioid detoxifications using buprenorphine. Methods: The study compared data obtained from two consecutive studies of early treatment engagement strategies. In one study (n = 364), opioid-addicted participants entered treatment through a Brief (5-day) buprenorphine detoxification. In the other study (n = 146), participants entered treatment through an Extended (i.e., 30-day) buprenorphine detoxification. Results: Results indicated a greater likelihood of successful completion and of transition among participants who received the Extended as compared to the Brief detoxification. Extended detoxification participants attended more counseling sessions and submitted fewer drug-positive urine specimens during the first 30 days of treatment, inclusive of detoxification, than did Brief detoxification participants. Conclusions: Results demonstrate that longer periods of detoxification improve participant engagement in treatment and early treatment outcomes. Scientific Significance: Current findings demonstrate the feasibility of implementing an extended buprenorphine detoxification within a community-based treatment clinic.

Young Heroin Users in Baltimore: A Qualitative Study

Despite findings that opioid detoxification serves little more than a palliative function, few patients who enter detoxification subsequently transition to long-term treatment. The current study evaluated intensive role induction (IRI), a strategy adapted from a single-session intervention previously shown to facilitate engagement of substance-dependent patients in drug-free treatment. IRI was delivered either alone or combined with case management (IRI+CM) to determine the capacity of each condition to enhance transition and engagement in long-term treatment of detoxification patients. Study participants were 240 individuals admitted to a 30-day buprenorphine detoxification delivered at a publicly funded outpatient drug treatment clinic. Following clinic intake, participants were randomly assigned to IRI, IRI+CM, or standard clinic treatment (ST). Outcomes were assessed in terms of adherence and satisfaction with the detoxification program, detoxification completion, and transition and retention in treatment following detoxification. Participants who received IRI and IRI+CM attended more counseling sessions during detoxification than those who received ST (both ps<.001). IRI, but not IRI+CM participants, were more likely to complete detoxification (p=.017), rated their counselors more favorably (p=.01), and were retained in long-term treatment for more days following detoxification (p=.005), than ST participants. The current study demonstrated that an easily administered psychosocial intervention can be effective for enhancing patient involvement in detoxification and for enabling their engagement in long-term treatment following detoxification.

Improvements in outcomes in methadone patients on probation/parole regardless of counseling early in treatment.

This study describes the characteristics of 67 young heroin users, interviewed using a semistructured qualitative questionnaire (QQ) as part of a larger study of 18- to 25-year-old heroin users seeking detoxification with buprenorphine at a drug treatment center in Baltimore. This new generation of heroin users has a different demographic profile compared to older heroin users in this area. Our data, supported by data from another clinic and from the Maryland State Alcohol and Drug Abuse Administration, seem to indicate that the younger heroin users in treatment settings are predominantly White, with a high proportion of women, often living in the suburbs. Based on responses to the QQ, all subjects initiated heroin use intranasally, usually in a group setting; 75% had subsequently gone on to use intravenously. The typical young heroin user in Baltimore Metropolitan area appears to be a young White man or woman from a middle/working-class background, with exposure to drug use among close contacts while growing up, experimenting with gateway drugs with peers before proceeding first to intranasal, and then intravenous heroin use, engaging in criminal activities to support the habit, repeatedly seeking help with assistance from family, but failing to sustain abstinence due to continued exposure to drug using peers and a poorly implemented plan of aftercare. Further research should focus on efforts to engage peer groups and families in order to improve treatment outcomes in young heroin users.

Impact of methadone with versus without drug abuse counseling on HIV risk: 4- and 12-month findings from a clinical trial.

Objective:This secondary data analysis examined the association between criminal justice (CJ) status and outcomes over 12 months of methadone maintenance treatment. Methods:In the parent study, 230 newly admitted patients were randomly assigned to methadone either with or without counseling for 4 months followed by standard methadone with counseling. Participants completed the ASI and urine drug testing at baseline and 4- and 12-month follow-up and the Treatment Readiness (TR) scale at baseline. The relationship between baseline CJ status (whether participants were on probation or parole), CJ status by study counseling condition, and CJ status by TR with heroin and cocaine use, illegal activity, days in treatment and treatment retention, arrests, and the number of days incarcerated or hospitalized during follow-up was examined. Results:Compared with participants not on probation/parole, probationers/parolees showed significant reductions in cocaine-positive tests from baseline to 12 months (P < 0.001). Probationers/parolees additionally reported significantly fewer days of illegal activity than nonprobationers/parolees at 12 months (P = 0.02). There was no relationship between CJ status and counseling condition for any outcomes. The relationship between CJ status and TR was significant only for cocaine-positive tests assessed over time (P = 0.017). Conclusions:Findings suggest that methadone participants on probation/parole showed improvements in outcomes in comparison with participants not on probation/parole, regardless of whether they received counseling during the first 4 months of treatment.

Adding Integrative Meditation with Ear Acupressure to Outpatient Treatment of Cocaine Addiction: A Randomized Controlled Pilot Study

Objective:Human immunodeficiency virus (HIV)-risk behaviors were examined at 4- and 12-month follow-up for 230 newly admitted methadone patients randomly assigned to receive either methadone only (n = 99) or methadone with drug abuse counseling (n = 131) in the first 4 months of treatment. Methods:The AIDS Risk Assessment was administered at baseline (treatment entry) and at 4- and 12-month follow-up. Linear mixed model analysis examined changes in HIV drug- and sex-risk behaviors over the 12 months in the total sample, drug-risk behaviors in the subsample that reported injecting drugs at baseline (n = 110), and sex-risk behaviors in the subsample that reported engaging in unprotected sex at baseline (n = 130). Results:Significant decreases over time were found in the frequencies of injecting, injecting with other injectors, and sharing cooker, cotton, or rinse water in the total sample and the injector subsample (P < 0.05). Decreases were also found in the frequencies of having sex without a condom either with someone who was not a spouse or primary partner or while high (P < 0.05) in the total sample and the frequencies of having sex without a condom and having sex without a condom while high in the unprotected-sex subsample (P < 0.05). No significant treatment group main effects or Treatment Group × Time interaction effects were found in any of the HIV-risk behaviors in the total sample or either subsample (P > 0.05). Conclusions:During the first 12 months of treatment, providing drug abuse counseling with methadone compared with providing methadone alone was not associated with significant changes in HIV-risk behaviors for methadone maintenance patients.

Acceptability of Technology-based Methods Substance Abuse Counseling in Office Based Buprenorphine Maintenance for Opioid Dependence

OBJECTIVES Cocaine addiction continues to be a major public health problem in the United States. With no U.S. Food and Drug Administration-approved pharmaceutical therapy, treatment often relies on psychosocial interventions. This pilot therapy development study attempts to examine the feasibility and preliminary efficacy of adding breathing-based Integrative Meditation and Ear Acupressure (IMEA) to outpatient treatment of cocaine addiction. DESIGN Fifty-six (56) cocaine-dependent patients were recruited from an outpatient addiction treatment facility in Baltimore, MD and randomized into either an IMEA or a treatment as usual (TAU) group for the 12 weeks of study, with weekly meetings to monitor treatment outcomes and to facilitate meditative therapy. OUTCOME MEASURES The outcome measures consisted of treatment retention rates by week 8 and 12; abstinence rates measured by 6 continuous weeks of negative urinalysis for cocaine, and addiction-related symptoms such as anxiety, craving, depression, and withdrawal symptoms. RESULTS With the assistance of simplified breath training and a portable MP4 device, 80% of IMEA participants self-reported practicing breathing or meditation 5+ days a week with acceptable compliance and showed strong interest in meditative techniques. Compared to TAU, IMEA participants reported significantly higher treatment completion rates by week 8 (89% versus 63%) and week 12 (81% versus 58%), higher abstinence rates (66% versus 34%), and significantly greater reduction in craving, anxiety, and other addiction-related symptoms. Some participants continued meditation after study completion. CONCLUSIONS It is feasible to add breathing-based IMEA to outpatient treatment of cocaine addiction. Although a number of limitations exist for this pilot study, further large-scale clinical trials and therapy-development studies of IMEA for addiction are warranted.
