The effectiveness of compulsory drug treatment: A systematic review

Psychosocial interventions to reduce alcohol consumption in concurrent problem alcohol and illicit drug users

BACKGROUND

Problem alcohol use is common among people who use illicit drugs (PWID) and is associated with adverse health outcomes. It is also an important factor contributing to a poor prognosis among drug users with hepatitis C virus (HCV) as it impacts on progression to hepatic cirrhosis or opioid overdose in PWID.

OBJECTIVES

To assess the effectiveness of psychosocial interventions to reduce alcohol consumption in PWID (users of opioids and stimulants).

SEARCH METHODS

We searched the Cochrane Drugs and Alcohol Group trials register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, CINAHL, and PsycINFO, from inception up to August 2017, and the reference lists of eligible articles. We also searched: 1) conference proceedings (online archives only) of the Society for the Study of Addiction, International Harm Reduction Association, International Conference on Alcohol Harm Reduction and American Association for the Treatment of Opioid Dependence; and 2) online registers of clinical trials: Current Controlled Trials, ClinicalTrials.gov, Center Watch and the World Health Organization International Clinical Trials Registry Platform.

SELECTION CRITERIA

We included randomised controlled trials comparing psychosocial interventions with other psychosocial treatment, or treatment as usual, in adult PWIDs (aged at least 18 years) with concurrent problem alcohol use.

DATA COLLECTION AND ANALYSIS

We used the standard methodological procedures expected by Cochrane.

MAIN RESULTS

We included seven trials (825 participants). We judged the majority of the trials to have a high or unclear risk of bias.The psychosocial interventions considered in the studies were: cognitive-behavioural coping skills training (one study), twelve-step programme (one study), brief intervention (three studies), motivational interviewing (two studies), and brief motivational interviewing (one study). Two studies were considered in two comparisons. There were no data for the secondary outcome, alcohol-related harm. The results were as follows.Comparison 1: cognitive-behavioural coping skills training versus twelve-step programme (one study, 41 participants)There was no significant difference between groups for either of the primary outcomes (alcohol abstinence assessed with Substance Abuse Calendar and breathalyser at one year: risk ratio (RR) 2.38 (95% confidence interval [CI] 0.10 to 55.06); and retention in treatment, measured at end of treatment: RR 0.89 (95% CI 0.62 to 1.29), or for any of the secondary outcomes reported. The quality of evidence for the primary outcomes was very low.Comparison 2: brief intervention versus treatment as usual (three studies, 197 participants)There was no significant difference between groups for either of the primary outcomes (alcohol use, measured as scores on the Alcohol Use Disorders Identification Test (AUDIT) or Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) at three months: standardised mean difference (SMD) 0.07 (95% CI -0.24 to 0.37); and retention in treatment, measured at three months: RR 0.94 (95% CI 0.78 to 1.13), or for any of the secondary outcomes reported. The quality of evidence for the primary outcomes was low.Comparison 3: motivational interviewing versus treatment as usual or educational intervention only (three studies, 462 participants)There was no significant difference between groups for either of the primary outcomes (alcohol use, measured as scores on the AUDIT or ASSIST at three months: SMD 0.04 (95% CI -0.29 to 0.37); and retention in treatment, measured at three months: RR 0.93 (95% CI 0.60 to 1.43), or for any of the secondary outcomes reported. The quality of evidence for the primary outcomes was low.Comparison 4: brief motivational intervention (BMI) versus assessment only (one study, 187 participants)More people reduced alcohol use (by seven or more days in the past month, measured at six months) in the BMI group than in the control group (RR 1.67; 95% CI 1.08 to 2.60). There was no difference between groups for the other primary outcome, retention in treatment, measured at end of treatment: RR 0.98 (95% CI 0.94 to 1.02), or for any of the secondary outcomes reported. The quality of evidence for the primary outcomes was moderate.Comparison 5: motivational interviewing (intensive) versus motivational interviewing (one study, 163 participants)There was no significant difference between groups for either of the primary outcomes (alcohol use, measured using the Addiction Severity Index-alcohol score (ASI) at two months: MD 0.03 (95% CI 0.02 to 0.08); and retention in treatment, measured at end of treatment: RR 17.63 (95% CI 1.03 to 300.48), or for any of the secondary outcomes reported. The quality of evidence for the primary outcomes was low.

AUTHORS' CONCLUSIONS

We found low to very low-quality evidence to suggest that there is no difference in effectiveness between different types of psychosocial interventions to reduce alcohol consumption among people who use illicit drugs, and that brief interventions are not superior to assessment-only or to treatment as usual. No firm conclusions can be made because of the paucity of the data and the low quality of the retrieved studies.

Civil commitment experiences among opioid users

INTRODUCTION

Civil commitment is an increasingly used policy intervention to combat the opioid epidemic. Yet little is known about persons who get committed and outcomes following commitment for opioid use. In the current cross-sectional study, we compared the characteristics of persons with and without a history of civil commitment, and the correlates of post-commitment abstinence.

METHODS

Between October 2017 and May 2018, we surveyed consecutive persons entering a brief, inpatient opioid detoxification (n = 292) regarding their lifetime experiences with civil commitment for opioid use.

RESULTS

Participants averaged 34.6 years of age, 27.1% were female, and 78.1% were White. Seventy-eight (26.7%) experienced civil commitment for opioid use at least once in their lifetime. Committed individuals had significantly higher rates of fentanyl, heroin, and injection drug use, drug overdoses, past incarceration, current criminal justice involvement, and past medication treatment for opioid use (p < .05). The average time to relapse following commitment was 72 days, although 33.8% relapsed on the same day of their release. Longer post-commitment abstinence was significantly associated with post-commitment medication treatment, higher perceived procedural justice (i.e., fairness) during the commitment hearing, positive attitude and higher motivation at the end of commitment, and improvement in attitude during commitment (p < .05).

CONCLUSION

Opioid users who experience civil commitment constitute an especially high risk group. A positive commitment experience and post-commitment medication treatment are associated with longer post-commitment abstinence.

Chinese Female Drug Users' Experiences and Attitudes With Institutional Drug Treatment

With its rapid economic growth and the increased influence of Western culture, China has become a drug-consuming country. Forty-six semistructured interviews were conducted in a compulsory drug treatment institution to document Chinese female drug users' experiences with and attitudes toward two mandated treatment modalities: vocational training and educational activities. Detainees required to participate in first institutional treatment showed enthusiasm and had more positive attitudes; those who had entered the compulsory treatment facilities 2 or more times generally had a negative outlook on their pursuit of abstinence. Although female detainees achieved detoxification in the institution, many relapsed upon release to their community, indicating the institutional compulsory treatment model's failure to ensure long-term abstinence. By revealing four main flaws of the current institutional compulsory treatment, this study indicates the need for a comprehensive treatment system that combines improvements to institutional treatment and development of community-based treatment to address different stages of abstinence.

Time-dependent neuronal changes associated with craving in opioid dependence: an fMRI study

Relapse after initially successful treatment is a significant problem facing the treatment of opioid dependence. Evidence suggests craving elicited by re‐exposure to drug cues may precipitate relapse. Attempts to identify neural biomarkers of cue‐elicited craving have yielded inconsistent findings. We aimed to apply a novel continuous functional magnetic resonance imaging technique to follow the minute‐to‐minute evolution of brain responses, which correlate with the waxing and waning of craving. Newly detoxified male opioid‐dependent patients and healthy control participants attended two separate, counterbalanced, functional magnetic resonance imaging scanning sessions during which they viewed a 10‐minute video (drug cue or neutral cue) followed by 5 minutes of fixation. Participants rated the intensity of their craving throughout each session. We hypothesized that subcortical/ventral prefrontal cortex (PFC) regions and dorsal PFC regions would show different associations with craving reflecting their putative roles in appetitive processing versus cognitive control. Compared with controls, drug cue (minus neutral cue) video recruited the left amygdala and was temporally correlated with craving. In contrast, dorsal anterior cingulate blood‐oxygen‐level‐dependent signal time course was higher than controls only during a period after cue exposure when craving levels were declining. Against expectations, neither the ventral striatum nor ventral PFC was significantly recruited by drug cue exposure. Findings suggest that the amygdala has a central role in craving, whereas the dorsal anterior cingulate may control craving in treatment‐seeking patients. Time course analysis yielded new insights into the neural substrates of craving that could objectively validate development of psychological and pharmacological approaches to sustained abstinence.

Compulsory treatment of drug use in Southeast Asian countries

BACKGROUND

Several Southeast Asian countries have implemented compulsory drug detention centres in which people who use or are suspected of using drugs, mainly amphetamine-type stimulants, are confined without their consent and in most cases without due process and clinical evaluation of their substance use disorder. Given these facilities' lack of access to evidence-based drug dependence treatment, and the human rights implications of peoples' arbitrary detention under the pretext of "treatment", international organizations have called for their closure. The aim of this study was to estimate recent numbers of compulsory drug treatment centres and of people in these centres in the region.

METHODS

We conducted an analysis of cross-sectional governmental data collected from seven countries in the region with compulsory drug detention centres, namely Cambodia, China, Lao PDR, Malaysia, the Philippines, Thailand and Viet Nam. We computed descriptive data provided by government representatives for the period between 2012 and 2014.

RESULTS

The total number of people in compulsory detention centres overall decreased by only 4% between 2012 and 2014. In 2014, over 450,000 people were detained in 948 facilities in the seven countries. While only two countries decreased the number of compulsory detention centres, most countries increased the number of people detained.

CONCLUSIONS

In spite of international calls for the closure of compulsory detention centres, the number of facilities and detained people remained high in the seven countries included in the analysis. These officially reported figures are concerning regarding access to effective drug dependence treatment and given the potential for additional human rights abuses within compulsory detention centers. Further concerted policy and advocacy efforts should support transition of treatment for people with drug dependence towards human rights-based and evidence-based drug dependence treatment. Expansion of existing drug and HIV services in the community rather than compulsory treatment modalities will effectively address the region's drug and HIV burden.

Increased non-fatal overdose risk associated with involuntary drug treatment in a longitudinal study with people who inject drugs

AIM

To assess the effect of involuntary drug treatment (IDT) on non-fatal overdose among people who inject drugs (PWID).

DESIGN

Longitudinal study.

SETTING

Tijuana, Mexico.

PARTICIPANTS

Baseline sample of 671 PWID included 258 (38.4%) women and 413 (61.6%) men.

MEASUREMENTS

Primary independent variables were reported recent (i.e. past 6 months) non-fatal overdose event (dependent variable) and IDT. Substance use the day of the non-fatal overdose was also examined.

FINDINGS

From 2011 to 2017, 213 participants (31.7%) reported a recent non-fatal overdose and 103 (15.4%) reported recent IDT. Heroin, in combination with methamphetamine and tranquilizers, were the drugs most reported at the day of the event. IDT significantly increased the odds of reporting a non-fatal overdose event [adjusted odds ratio (aOR) = 1.76; 95% confidence interval (CI) = 1.04-2.96]. Odds of non-fatal overdose also increased independently for each additional injection per day (aOR = 1.05; 95% CI = 1.02-1.08), recent tranquilizer use (aOR = 1.92; 95% CI = 1.41-2.61) and using hit doctors (aOR = 1.68; 95% CI = 1.29-2.18) and decreased with age (aOR = 0.97 per year, 95% CI = 0.95-0.99).

CONCLUSIONS

Recent involuntary drug treatment in Mexico is a risk factor for non-fatal drug overdose.

Commentary on Rafful et al. (2018): Unpacking involuntary interventions for people who use drugs

Involuntary interventions for substance use disorders are less effective and potentially more harmful than voluntary treatment, and involuntary centers often serve as venues for abuse. Scaling up voluntary, evidence-based, low-barrier treatment options might invalidate the perceived necessity of involuntary interventions, and could go a long way toward reducing overdose risk.

The Role of Civil Commitment in the Opioid Crisis

This article seeks to shed light on civil commitment in the context of the opioid crisis, to sketch the existing legal landscape surrounding civil commitment, and to illustrate the relevant medical, ethical, and legal concerns that policymakers must take into account as they struggle to find appropriate responses to the crisis.

Associations of the Neighborhood Environment With Substance Use: A Cross-sectional Investigation Among Patients in Compulsory Drug Detention Centers in Thailand

Objectives

To identify the associations of characteristics of the neighborhood environment with substance abuse among clients receiving treatment for drug abuse in Thailand.

Methods

A cross-sectional study was conducted of 1128 drug addicts from 28 neighborhoods who were receiving treatment at all 7 compulsory drug detention centers in Thailand. A trained interviewer conducted structured interviews with the subjects about substance use and the perceived neighborhood environment in their community. A multilevel logistic regression model was applied to estimate the effects of the neighborhood environment on substance use.

Results

The majority of participants, 53.8% only used methamphetamine pills, 31.3% used other illicit drugs as well as methamphetamine pills, and 14.9% used an illicit drug other than methamphetamine. Three neighborhood characteristics were associated with substance use. A 1-unit increase in the perceived neighborhood cohesion score was associated with a 15% reduction in methamphetamine pill use and an 11% reduction of the use of both methamphetamine pills and another illicit drug. Conversely, a 1-unit increase in perceived neighborhood crime predicted 19 and 14% increases in the use of methamphetamine pills and the use of both methamphetamine pills and another illicit drug, respectively. In addition, a 1-unit increase in the scores for stigma surrounding addiction corresponded to a 25% increase of the use of methamphetamine pills and a 12% increase in the use of both methamphetamine pills and another illicit drug.

Conclusions

Substance use among drug addicts was influenced by characteristics of the neighborhood environment. Therefore, prevention and intervention strategies should be designed based on a consideration of the impact of neighborhood context on substance use behaviors.

Human rights and political crisis in Brazil: Public health impacts and challenges

In 31 August 2016, Brazilian president Dilma Rousseff was impeached and replaced by her vice president Michel Temer. Herein, we examine how the conservative agenda of Mr Temer and his supporters is influencing key decisions in the human rights and public health arena in Brazil. The government's austerity agenda includes severe cuts in critical areas such as health, education and science, jeopardising well-known strategies such as the Brazilian Public Health System (SUS) and nationwide cash transfer program, 'Bolsa Familia' - both benefited millions and were the largest of their kind in the world. Mr Temer's decisions show not only severe cuts in critical areas but also a political agenda that clearly demonstrates a broad shift away from the progressivism and social agenda presented and supported by its predecessors. Most vulnerable groups such as the LGBTQ community, women, people who use drugs and disenfranchised communities have been severely affected. Mr Temer's administration is putting Brazil far from its once nationwide goal to foster free and universal health care access and social equity for all its citizens. The near future for Brazil is unknown, but both national and international communities anticipate severe problems within the national human rights arena, if nothing changes.

CCT: Conditional Cash Transfer; LGBTQ: Lesbian, Gay, Bisexual, Transgender and Queer (and/or Questioning); SUS: Brazilian Public Health System.

Relapse to opioid use in opioid-dependent individuals released from compulsory drug detention centres compared with those from voluntary methadone treatment centres in Malaysia: a two-arm, prospective observational study

BACKGROUND

Detention of people who use drugs into compulsory drug detention centres (CDDCs) is common throughout East and Southeast Asia. Evidence-based pharmacological therapies for treating substance use disorders, such as opioid agonist treatments with methadone, are generally unavailable in these settings. We used a unique opportunity where CDDCs coexisted with voluntary drug treatment centres (VTCs) providing methadone in Malaysia to compare the timing and occurrence of opioid relapse (measured using urine drug testing) in individuals transitioning from CDDCs versus methadone maintenance in VTCs.

METHODS

We did a parallel, two-arm, prospective observational study of opioid-dependent individuals aged 18 years and older who were treated in Malaysia in the Klang Valley in two settings: CDDCs and VTCs. We used sequential sampling to recruit individuals. Assessed individuals in CDDCs were required to participate in services such as counselling sessions and manual labour. Assessed individuals in VTCs could voluntarily access many of the components available in CDDCs, in addition to methadone therapy. We undertook urinary drug tests and behavioural interviews to assess individuals at baseline and at 1, 3, 6, 9, and 12 months post-release. The primary outcome was time to opioid relapse post-release in the community confirmed by urinary drug testing in individuals who had undergone baseline interviewing and at least one urine drug test (our analytic sample). Relapse rates between the groups were compared using time-to-event methods. This study is registered at ClinicalTrials.gov (NCT02698098).

FINDINGS

Between July 17, 2012, and August 21, 2014, we screened 168 CDDC attendees and 113 VTC inpatients; of these, 89 from CDDCs and 95 from VTCs were included in our analytic sample. The baseline characteristics of the two groups were similar. In unadjusted analyses, CDDC participants had significantly more rapid relapse to opioid use post-release compared with VTC participants (median time to relapse 31 days [IQR 26-32] vs 352 days [256-unestimable], log rank test, p<0·0001). VTC participants had an 84% (95% CI 75-90) decreased risk of opioid relapse after adjustment for control variables and inverse propensity of treatment weights. Time-varying effect modelling revealed the largest hazard ratio reduction, at 91% (95% CI 83-96), occurs during the first 50 days in the community.

INTERPRETATION

Opioid-dependent individuals in CDDCs are significantly more likely to relapse to opioid use after release, and sooner, than those treated with evidence-based treatments such as methadone, suggesting that CDDCs have no role in the treatment of opioid-use disorders.
