Four-year follow-up of imprisoned male heroin users and methadone treatment: mortality, re-incarceration and hepatitis C infection

Tuberculosis treatment outcomes after transfer or release from incarceration: A retrospective cohort study from Brazil

Background

Tuberculosis (TB) disproportionately affects people deprived of liberty. Prior studies have shown higher TB treatment completion rates among incarcerated individuals compared to the general population. However, little is known about how incarceration-related movements such as transfers between facilities or releases to the community affect TB treatment outcomes.

Methods

We linked person-level incarceration data with TB notifications data from the Notifiable Disease Information System for the Brazilian state of Mato Grosso do Sul between January 2006 and December 2018. We constructed a cohort of individuals newly diagnosed with drug-susceptible TB who initiated treatment while incarcerated. We compared treatment outcomes between individuals who remained in the same carceral facility and those who were transferred to other facilities or released from incarceration during treatment. We computed the covariate-adjusted relative risk of unfavorable treatment outcomes for individuals transferred or released during treatment.

Results

We identified 1,274 individuals who initiated TB treatment while incarcerated. Of these individuals, 849 (66.6%) remained in the same carceral facility, 259 (20.3%) were transferred to other facilities, and 166 (13.0%) were released to the community during treatment. Among those who remained in the same carceral facility, 72.3% (614/849) were successfully treated within eight months following treatment initiation. In contrast, only 61.0% (158/259) of those who were transferred and 49.4% (82/166) of those who were released achieved TB treatment success within eight months. After adjusting for covariates, the risk of unfavorable treatment outcomes was 1.4 (95% CI: 1.2 to 1.7) times as high for individuals transferred to other facilities and 1.6 (95% CI: 1.3 to 2.0) times as high for individuals released from incarceration, compared to those who remained incarcerated in the same facility during treatment. For individuals released less than two months into treatment, the risk of unfavorable treatment outcomes was twice as high (adjusted relative risk [aRR]:2.1, 95% CI: 1.6 - 2.6).

Conclusions

Transfers between facilities and releases from incarceration are common and may pose barriers to TB treatment completion. Strategies for ensuring continuity of care across carceral facilities and between prison and community health systems are urgently needed to improve TB outcomes for individuals impacted by incarceration.

Death and disappearance: Measuring racial disparities in mortality and life expectancy among people in state prisons, United States 2000-2014

BACKGROUND

Research on carceral institutions and mortality finds that people in prisons and jails have a high risk of death immediately following release from custody and that while incarcerated, racial disparities in prisoner mortality counter observed death patterns among similarly situated non-incarcerated, demographic groups. Yet, many of these studies rely on data prior to the millennium, during the COVID-19 pandemic, or are relegated to a small number or select group of states. In this paper, we explore changes in mortality and life-expectancy among different demographic groups, before and after the Great Recession, across forty-four states that reported deaths in custody to the federal government between 2000 and 2014.

METHODS

Drawing on a novel dataset created and curated, we calculate standard, age- specific quantities (death rates and life-expectancy) using period lifetable methods, disaggregated by race and sex, across three different periods (2000-2004, 2005-2009, and 2010-2014) for each state. Ordinary least squares regression models with state and year fixed-effects are included to examine state-level factors that may explain differences in prisoner mortality rates between 2000 and 2014. We also benchmark death counts reported to federal agencies with official state reports to cross-validate general mortality patterns.

RESULTS

Among imprisoned men, age-specific trends in mortality have shifted across the three periods. Following the Great Recession and the push for criminal justice reforms, prisoner mortality dropped significantly and is concentrated at older ages among men during 2010-2014; the shifting pattern of mortality means that men age 30 in 2010-2014 had similar death rates as men in their early 20s during 2000-2004, representing a 7.5 year shift in age-specific mortality rates. Gains in the mortality decline were disproportionately experienced by Non-Hispanic White and Non-Hispanic Black men, with the latter experiencing the greatest gains in life-expectancy of any demographic group. State-level violent crime rates are strongly and positively associated with prison mortality rates across states, net of socioeconomic and political factors. The large and significant disappearance of deaths in prisons from official data reported to federal agencies calls into question the narrowing gap in racial disparities among people in carceral facilities.

CONCLUSIONS

Legal decisions and social policies aimed at reducing mortality may be most effective in the short-run; however, the effects of these policy changes may fadeout over time. Research should clearly discern whether changes in mortality rates across states are due to diminished gains in social policies or increases in the disappearance (or underreporting) of deaths in custody. Understanding how and why gains in survivorship may stall is important for aligning health initiatives with social policy to facilitate maximal and consistent mortality declines for all demographic groups.

Opioid substitution treatment, relapse and addiction-related outcomes in prison setting and after release: A longitudinal study

Aims: Opioid addiction is a common problem among prisoners. The aim of this study was to examine differences between people who are incarcerated receiving opioid substitution treatment (OST) and those not receiving OST on addiction-related outcome variables during incarceration and after release from prison. Variables covered illicit use of opioids, non-prescribed substitution medication and other substances, opioid withdrawal symptoms, opioid craving, non-fatal overdoses and post-release substitution treatment. Design: Interviews (European Addiction Severity Index, EuropASI) were conducted with 247 participants in German prisons before release. Participants were interviewed again 1 month and 3-6 months after release from prison. Results: During incarceration, participants who received OST used less illicit opioids and non-prescribed substitution medication than those who did not receive OST. After release from prison, participants in the OST group reported less illicit opioid use and less non-prescribed substitution medication use, as well as less opioid craving. Participants who received OST in prison were more likely to be in OST at post-release follow-up than those who had not received in-prison OST. Conclusion: OST appears to have a positive effect on illicit opioid use and craving both in prison and after release, as well as on treatment at follow-up, which can be considered a protective factor.

Higher methadone dose at time of release from prison predicts linkage to maintenance treatment for people with HIV and opioid use disorder transitioning to the community in Malaysia

BACKGROUND

Incarcerated people with HIV and opioid-dependence often experience poor post-release outcomes in the absence of methadone maintenance treatment (MMT). In a prospective trial, we assessed the impact of methadone dose achieved within prison on linkage to MMT after release.

METHODS

From 2010 to 2014, men with HIV (N = 212) and opioid dependence before incarceration were enrolled in MMT within 6 months of release from Malaysia's largest prison and followed for 12-months post-release. As a prospective trial, allocation to MMT was at random and later by preference design (predictive nonetheless). MMT dosing was individually targeted to minimally achieve 80 mg/day. Time-to-event analyses were conducted to model linkage to MMT after release.

FINDINGS

Of the 212 participants allocated to MMT, 98 (46 %) were prescribed higher dosages (≥80 mg/day) before release. Linkage to MMT after release occurred in 77 (36 %) participants and significantly higher for those prescribed higher dosages (46% vs 28 %; p = 0.011). Factors associated with higher MMT dosages were being married, on antiretroviral therapy, longer incarceration periods, having higher levels of depression, and methadone preference compared to randomization. After controlling for other variables, being prescribed higher methadone dosage (aHR: 2.53, 95 %CI: 1.42-4.49) was the only independent predictor of linkage to methadone after release.

INTERPRETATION

Higher doses of methadone prescribed before release increased the likelihood of linkage to MMT after release. Methadone dosing should be introduced into international guidelines for treatment of opioid use disorder in prisons and further post-release benefits should be explored.

Incidence of hepatitis C virus infection in the prison setting: The SToP-C study

People in prison are at high risk of HCV given high injecting drug use prevalence. This study evaluated HCV incidence and associated injecting drug use characteristics in prison. The SToP-C study enrolled people incarcerated in four Australian prisons. Participants were tested for HCV at enrolment and then every 3-6 months (October-2014 to November-2019). Participants eligible for this analysis included those at-risk of HCV primary infection (anti-HCV negative) or re-infection (anti-HCV positive, HCV RNA negative) with follow-up assessment. A total of 1643 eligible participants were included in analyses (82% male; median age 33 years; 30% injected drugs in prison; 1818 person-years of follow-up). Overall HCV incidence was 6.11/100 person-years (95%CI: 5.07-7.35), with higher rate of re-infection (9.34/100 person-years; 95%CI: 7.15-12.19) than primary infection (4.60/100 person-years; 95%CI: 3.56-5.96). In total population (n = 1643), HCV risk was significantly higher among participants injecting drugs in prison [vs. no injecting; adjusted hazard ratio (aHR): 10.55, 95%CI: 5.88-18.92), and those who were released and re-incarcerated during follow-up (vs. remained incarcerated; aHR: 1.60, 95%CI: 1.03-2.49). Among participants who injected recently (during past month, n = 321), HCV risk was reduced among those receiving high-dosage opioid agonist therapy (OAT), i.e. methadone ≥60 mg/day or buprenorphine ≥16 mg/day, (vs. no OAT, aHR: 0.11, 95%CI: 0.02-0.80) and increased among those sharing needles/syringes without consistent use of disinfectant to clean injecting equipment (vs. no sharing, HR: 4.60, 95%CI: 1.35-15.66). This study demonstrated high HCV transmission risk in prison, particularly among people injecting drugs. High-dosage OAT was protective, but improved OAT coverage and needle/syringe programmes to reduce sharing injecting equipment are required.

Recovery Capital Correlates With Less Methamphetamine Use and Crime in the Community

OBJECTIVES

Reentry postcorrectional involvement is a high-risk time for patients with a history of addiction. We investigated whether participation in an addiction medicine clinic with active case management led to improvements in patients' recovery capital and whether there were associated changes in criminal activity and co-occurring methamphetamine or alcohol use.

METHODS

Participants (n = 136) were patients with an opioid or stimulant use disorder who had Department of Corrections involvement in the preceding year, who completed the Assessment of Recovery Capital (ARC) and reported criminal activity and days of methamphetamine or alcohol use twice over a 6-month study. Three logistic regression models were used to assess changes in total ARC with criminal activity, alcohol use, and methamphetamine use over the previous 30 days.

RESULTS

Baseline mean (SD) ARC scores were 34.1 (11.1) and increased to a mean (SD) score of 40.3 (9.4) at study end. A 1-SD shift in ARC was significantly protective across outcomes, with adjusted odds ratios of 0.32, 0.18, and 0.34 for any past 30-day criminal activity, alcohol use, or methamphetamine use. There was no significant difference in baseline ARC, crimes committed, days of alcohol use, or days of methamphetamine use for study completers versus noncompleters; however, unmeasured confounders may have had a differential impact on retention.

CONCLUSIONS

Recovery capital provides an additional framework to help address patients' substance use and criminal activity in a multifaceted way, which is especially important in the postincarceration community. Recovery capital is dynamic and has multiple areas to target psychosocial interventions.

Sex Differences in Recovery Capital Gains Post-Incarceration

BACKGROUND

People with substance use disorders are highly prevalent in the carceral system. Recovery capital (RC) is the resources available to an individual to initiate or maintain substance use cessation. Sex differences have been identified in RC during both active substance use and recovery in the general population, however, less is known about these sex differences in the post-incarceration population.

METHODS

Participants (n = 136) were those with an opioid or stimulant use disorder with past year involvement with the Iowa criminal justice system (USA), who completed the Assessment of Recovery Capital (ARC) twice over a six-month cohort study. Participants were involved in an addiction clinic that utilized active case management. Analysis of covariance evaluated changes in ARC during the study. Separate models compared total ARC and individual ARC domains, with sex as the independent variable of interest. Model means were generated for interpretation based on sex, comparing baseline and study endpoint ARC scores.

RESULTS

There were no baseline sex differences in total ARC. ARC increased significantly for the group, however, males showed disproportionate growth. Females ended the study with a mean ARC of 37.8 (SD= 9.3) and males finished at 41.6 (SD= 9.3), which was a significant difference (p = 0.044); this significant difference was driven by ARC subdomains of 'Psychological Health' and 'Physical Health.'

CONCLUSIONS

People post-incarceration are at high risk for return to substance use. Treatment that is informed by sex-based differences may have the potential to decrease the differing rates of growth in RC between sexes.

Is use of opioid agonist treatment associated with broader primary healthcare use among men with recent injecting drug use histories following release from prison? A prospective cohort study

BACKGROUND

A precipitous decline in health status among people recently released from prison is common. In Victoria, Australia, opioid agonist treatment (OAT) in the community involves frequent contact with primary care, potentially facilitating broader use of primary healthcare services. Among a cohort of men who injected drugs regularly pre-imprisonment, we estimated differences in rates of primary healthcare use and medication dispensation between people who did and did not receive OAT post-release.

METHODS

Data came from the Prison and Transition Health Cohort Study. Three-month post-release follow-up interviews were linked with primary care and medication dispensation records. Generalised linear models were fit with one exposure (OAT: none/partial/complete) for 13 outcomes relating to primary healthcare use, pathology testing, and medication dispensation, adjusted for other covariates. Coefficients were reported as adjusted incidence rate ratios (AIRR).

RESULTS

Analyses included 255 participants. Compared to no OAT use, both partial and complete OAT use were associated with increased rates of standard (AIRR: 3.02, 95%CI: 1.88-4.86; AIRR: 3.66, 95%CI: 2.57-5.23), extended (AIRR: 2.56, 95%CI: 1.41-4.67; AIRR: 2.55, 95%CI: 1.60-4.07) and mental health-related (AIRR: 2.71, 95%CI: 1.42-5.20; AIRR: 2.27, 95%CI: 1.33-3.87) general practitioner (GP) consultations, total medication (AIRR: 1.88, 95%CI: 1.19-2.98; AIRR: 2.40, 95%CI: 1.71-3.37), benzodiazepine (AIRR: 4.99, 95%CI: 2.81-8.85; AIRR: 8.30, 95%CI: 5.28-13.04) and gabapentinoid (AIRR: 6.78, 95%CI: 3.34-13.77; AIRR: 4.34, 95%CI: 2.37-7.94) dispensations, respectively. Partial OAT use was also associated with increased after-hours GP consultations (AIRR: 4.61, 95%CI: 2.24-9.48) and complete OAT use? with increased pathology utilisation (e.g. haematological, chemical, microbiological or immunological tissue/sample testing; AIRR: 2.30, 95%CI: 1.52-3.48).

CONCLUSION

We observed higher rates of primary healthcare use and medication dispensation among people who reported partial and complete OAT use post-release. Findings suggest that access to OAT post-release may have a collateral benefit in supporting broader health service utilisation, underscoring the importance of retention in OAT after release from prison.

Evaluation of a complex intervention for prisoners with common mental health problems, near to and after release: the Engager randomised controlled trial

BACKGROUND

Many male prisoners have significant mental health problems, including anxiety and depression. High proportions struggle with homelessness and substance misuse.

AIMS

This study aims to evaluate whether the Engager intervention improves mental health outcomes following release.

METHOD

The design is a parallel randomised superiority trial that was conducted in the North West and South West of England (ISRCTN11707331). Men serving a prison sentence of 2 years or less were individually allocated 1:1 to either the intervention (Engager plus usual care) or usual care alone. Engager included psychological and practical support in prison, on release and for 3-5 months in the community. The primary outcome was the Clinical Outcomes in Routine Evaluation Outcome Measure (CORE-OM), 6 months after release. Primary analysis compared groups based on intention-to-treat (ITT).

RESULTS

In total, 280 men were randomised out of the 396 who were potentially eligible and agreed to participate; 105 did not meet the mental health inclusion criteria. There was no mean difference in the ITT complete case analysis between groups (92 in each arm) for change in the CORE-OM score (1.1, 95% CI -1.1 to 3.2, P = 0.325) or secondary analyses. There were no consistent clinically significant between-group differences for secondary outcomes. Full delivery was not achieved, with 77% (108/140) receiving community-based contact.

CONCLUSIONS

Engager is the first trial of a collaborative care intervention adapted for prison leavers. The intervention was not shown to be effective using standard outcome measures. Further testing of different support strategies for prison with mental health problems is needed.

Discontinuation of opioid agonist treatment following release from prison in a cohort of men who injected drugs prior to imprisonment in Victoria, Australia: A discrete-time survival analysis

BACKGROUND

Retention in opioid agonist treatment (OAT) following release from prison is associated with improved outcomes, however factors associated with post-release OAT discontinuation in Australia are poorly understood. We examined post-release OAT discontinuation in a cohort of men who engaged in approximately monthly injecting drug use (IDU) prior to imprisonment in Victoria, Australia.

METHODS

Longitudinal data were used to calculate incidence of first-event post-release OAT discontinuation among men released from prison receiving OAT, and single-event discrete-time survival methods were used to estimate associations with post-release OAT discontinuation.

RESULTS

Among 110 participants, 55 OAT discontinuations were observed in the two years post-release, an overall crude incidence rate (IR) of 46 per 100 person-years (PY) (95 % confidence interval [95 %CI]: 36-60 per 100PY). Incidence was greatest between release from prison and first follow-up (IR: 84 per 100PY, 95 %CI: 62-116 per 100PY). Initiating OAT during index imprisonment (versus transitioning from community OAT; adjusted hazard rate [AHR]: 2.17, 95 %CI: 1.14-4.13) and identifying as Aboriginal and/or Torres Strait Islander (AHR: 4.95, 95 %CI: 2.00-12.25) were associated with an increased hazard of OAT discontinuation.

CONCLUSION

In a cohort of men with recent histories of IDU released from prison receiving OAT, half reported OAT discontinuation within two years of release from prison, with incidence of discontinuation greatest soon after prison-release. Targeted support for men who initiate OAT during episodes of imprisonment and Aboriginal and/or Torres Strait Islander peoples is necessary to reduce incidence of OAT discontinuation among people at greatest risk of discontinuation.

HIV and Incarceration: Implications for HIV-Positive People Who Use Illicit Drugs During a Seek, Test, Treat, and Retain Initiative in Canada

People who use illicit drugs (PWUD) face increased exposure to the criminal justice system and disproportionate burdens of HIV infection. This article investigated the effects of incarceration on HIV cascade of care-related measures in a setting with a community-wide seek, test, treat, and retain (STTR) initiative. Using a multivariable logistic regression analysis of 935 HIV-positive PWUD between 2005 and 2017, this article showed a negative relationship between periods of incarceration and two measures of engagement in clinical care for HIV among PWUD: recent dispensation of antiretroviral therapy and suppression of HIV viral load. These findings suggest the benefits of STTR-based efforts are limited by exposure to the criminal justice system and highlight the need for additional supports for PWUD with HIV exposed to the criminal justice system.

Hepatitis C virus risk among young people who inject drugs

Background

Injection drug use (IDU) is the leading risk factor for hepatitis C virus (HCV) transmission in the U.S. While the general risk factors for HCV transmission are known, there is limited work on how these factors interact and impact young people who inject drugs (YPWID).

Methods

Project data were drawn from a study of 539 New York City (NYC) residents ages 18-29 who were recruited via Respondent-Driven Sampling and, reported past-month non-medical use of prescription opioids and/or heroin. Analyses are based on a subsample of 337 (62%) who reported injecting any drug in the past 12 months. All variables were assessed via self-report, except HCV status, which was established via rapid antibody testing. Integrating the observed statistical associations with extant literature on HCV risk, we also developed a qualitative system dynamics (SD) model to use as a supplemental data visualization tool to explore plausible pathways and interactions among key risk and protective factors for HCV.

Results

Results showed a 31% HCV antibody prevalence with an overall incidence of 10 per 100 person-years. HCV status was independently correlated with having shared cookers with two or more people (AOR = 2.17); injected drugs 4–6 years (AOR = 2.49) and 7 or more years (AOR = 4.95); lifetime homelessness (AOR = 2.52); and having been incarcerated two or more times (AOR = 1.99). These outcomes along with the extant literature on HCV risk were used to develop the qualitative SD model, which describes a causal hypothesis around non-linearities and feedback loop structures underlying the spread of HCV among YPWID.

Conclusions

Despite ongoing harm reduction efforts, close to a third of YPWID in the community sample have been exposed to HCV, have risks for injection drug use, and face challenges with structural factors that may be preventing adequate intervention. The qualitative SD model explores these issues and contributes to a better understanding of how these various risk factors interact and what policies could potentially be effective in reducing HCV infections.

Multi-level implementation factors that influence scale-up of methadone maintenance treatment in Moldovan prisons: A qualitative study

INTRODUCTION

People who inject drugs (PWID) are overrepresented in prison populations, especially in the Eastern European and Central Asian region (EECA), where HIV incidence and mortality continue to rise. Modeling data suggest that methadone maintenance treatment (MMT) scale-up in prison with continuation after release could substantially reduce new HIV infections. Moldova, one of four countries in the EECA to have introduced MMT in prisons, has faced challenges with its scale-up.

METHOD

To improve implementation of MMT in Moldovan prisoners, we analyzed the qualitative interviews of 44 recently released Moldovan prisoners with opioid use disorder who either accepted or rejected MMT while incarcerated; these 44 were among a subset of 56 participants in a quantitative survey who had complete interview data. After translating and back-translating interviews, we used content analysis to identify key barriers and facilitators to MMT uptake.

RESULTS

Our qualitative analyses revealed that positive attitudes toward methadone facilitated treatment uptake, yet the study identified three thematic barriers as to why PWID do not accept MMT while in prison, including: 1) negative personal attitudes toward MMT; 2) stigmatization of MMT by informal hierarchies within prison; and 3) distrust of the formal prison hierarchy (i.e., administration), which provides MMT.

CONCLUSION

Overall, the social forces of the two prisoner hierarchies and distrust between them appeared to outweigh the perceived benefits of MMT and impacted MMT uptake. Here we provide strategies to promote MMT more effectively in prison settings.

Methadone within prison and linkage to and retention in treatment upon community release for people with opioid use disorder in Kyrgyzstan: Evaluation of a national program

BACKGROUND

HIV incidence in Eastern Europe and Central Asia (EECA) continues to increase, primarily among people who inject drugs (PWID) and people in prisons. In Kyrgyzstan, an estimated 35% of people in prison are PWID, and 10% have been diagnosed with HIV. In 2008, Kyrgyzstan became the first country in EECA to provide free and voluntary methadone in prisons. We examine the impact of this national program on methadone within prison as well as linkage to and retention in treatment upon release to the community.

METHODS

Administrative data from a national methadone registry with de-identified information were assessed retrospectively. We examined the delivery of methadone services, including the duration of treatment both within prison and after release, for all prisoners who were prescribed methadone in Kyrgyz prisons from 2008 to 2018. Reasons for discontinuing methadone, HIV status and methadone dose are also analyzed.

RESULTS

Between 2008 and 2018, nine of Kyrgyzstan's 16 prisons offered methadone, and 982 incarcerated people initiated methadone within prison. Prisoners prescribed methadone were mostly male (96.2%), in their mid-30s (mean=34.9 years), and had been incarcerated for a relatively long time (mean = 44.1 months); their mean treatment duration in prison was 12.5 months, and 31.6% had HIV. A subsample (N = 645; 65.7%) of these were released to the community. Of these 645 people, 356 (55.2%) were not taking methadone at the time of release, 128 (19.8%) were on methadone and continued it after release, and the remainder (N=161, 25.0%) were on methadone at the time of release, but subsequently discontinued it, most within the first 7 days after release. Among those continuing methadone, 14.8% (N=19) remained on treatment ≥ 12 months. Independent correlates of linkage to methadone after release included positive HIV status (adjusted hazard ratio (aHR)=1.55; p = 0.033), receipt of methadone before their incarceration (aHR=2.01; p = 0.039), and receipt of methadone at the time of release (aHR = 20.81; p<0.001).

CONCLUSION

This is the first evaluation of within-prison methadone treatment in EECA. Uptake of methadone within prison and retention in treatment after release were both low. Continuous maintenance of treatment throughout incarceration is an opportunity to optimize HIV prevention and link patients to methadone post-release.

Opioid-specific medication-assisted therapy and its impact on criminal justice and overdose outcomes

Background

The overlap between justice system involvement and drug use is well-documented. Justice-involved people who misuse opioids are at high risk for relapse and criminal recidivism. Criminal justice policymakers consider opioid-specific medication-assisted therapies (MATs) one approach for improving outcomes for this population. More research is needed that explores the impacts of opioid-specific MATs for justice-involved people.

Objectives

This study sought to assess the effects of opioid-specific MAT for reducing the frequency and likelihood of criminal justice and overdose outcomes for current or formerly justice-involved individuals.

Search Methods

Records were searched between May 7, 2021 and June 23, 2021. We searched a total of sixteen proprietary and open access databases that included access to gray literature and conference proceedings. The bibliographies of included studies and relevant reviews were also searched.

Selection Criteria

Studies were eligible for inclusion in the review if they: (a) assessed the effects of opioid-specific MATs on individual-level criminal justice or overdose outcomes; included (b) a current or formerly justice-involved sample; and (c) a randomized or strong quasi-experimental design; and c) were published in English between January 1, 1960 and October 31, 2020.

Data Collection and Analysis

We used the standard methodological procedures as expected by The Campbell Collaboration.

Main Results

Twenty studies were included, representing 30,119 participants. The overall risk of bias for the experimental studies ranged from "some" to "high" and for quasi-experimental studies ranged from "moderate" to "serious." As such, findings must be interpreted against the backdrop of less-than-ideal methodological contexts. Of the 20 included studies, 16 included outcomes that were meta-analyzed using mean log odds ratios (which were reported as mean odds ratios). Mean effects were nonsignificant for reincarceration (odds ratio [OR] = 0.93 [0.68, 1.26], SE = .16), rearrest (OR = 1.47 [0.70, 3.07], SE = 0.38), and fatal overdose (OR = 0.82 [0.56, 1.21], SE = 0.20). For nonfatal overdose, the average effect was significant (OR = 0.41 [0.18, 0.91], SE = 0.41, p < 0.05), suggesting that those receiving MAT had nearly 60% reduced odds of a nonfatal overdose.

Implications for Policy Practice and Research

The current review supports some utility for adopting MAT for the treatment of justice-involved people with opioid addiction, however, more studies that employ rigorous methodologies are needed. Researchers should work with agencies to improve adherence to medication regimens, study design, and collect more detailed information on participants, their criminal and substance use histories, onset, and severity. This would help clarify whether treatment and control groups are indeed comparable and provide better insight into the potential reasons for participant dropout, treatment failure, and the occurrence of recidivism or overdose. Outcomes should be assessed in multiple ways, if possible (e.g., self-report and official record), as reliance on official data alone may undercount participants' degree of criminal involvement.

Post-incarceration outcomes for individuals who continued methadone treatment while in Connecticut jails, 2014-2018

PURPOSE

To assess post-release outcomes associated with continuation of methadone treatment in correctional centers.

METHODS

This case-control study of the post-incarceration impact of pilot methadone programs operating in jails in New Haven and Bridgeport, Connecticut, USA was conducted in 2014-18. The study compared non-fatal overdose, fatal overdose, reincarceration, and resumption of methadone in the community experienced by 1564 eligible men, 660 (42.2 %) of whom continued treatment while incarcerated.

RESULTS

Continuation of methadone was associated with a significant decrease in non-fatal overdose (OR:0.55; 95 % CI: 0.36, 0.85) and a greater likelihood of resuming methadone treatment in the community post-release (OR:2.56; 95 % CI: 2.07, 3.16). Time to resumption of methadone was shortened by treatment while time to non-fatal overdose was increased. Treatment while incarcerated resulted in a modest but not significant decrease in fatal overdoses and no difference in reincarceration between those who did and did not receive methadone. However, resumption of methadone after release did significantly reduce fatal overdoses (OR = 0.26, 95 % CI: 0.11, 0.62, p = 0.002).

CONCLUSION AND RELEVANCE

Improvements in post-release outcomes of non-fatal overdose and treatment reengagement emphasize the benefits of continuing medication-based treatment for opioid use disorder within the criminal justice system for those receiving it prior to being incarcerated.

Examining a migration-based phenomenon of heroin use in an urban drug scene in Sao Paulo, Brazil

Purpose

Brazil’s street-based drug use is mostly characterized by non-injection psychostimulant (e.g. crack-cocaine) drug use in Brazil, with limited interventions and service availability. Recently, an influx of multi-ethnic migrants within an urban drug scene in Sao Paulo was associated with heroin use, a drug normatively absent from Brazil. The purpose of this paper is to characterize and compare heroin use-related characteristics and outcomes for an attending sub-sample of clients from a large community-based treatment centre (“CRATOD”) serving Sao Paulo’s local urban drug scene.

Design/methodology/approach

All non-Brazilian patients (n = 109) receiving services at CRATOD for 2013–2016 were identified from patient files, divided into heroin users (n = 40) and non-heroin users (n = 69). Based on chart reviews, select socio-demographic, drug use and health status (including blood-borne-virus and other infections per rapid test methods) were examined and bi-variately compared. Multi-variate analyses examined factors independently associated with heroin use.

Findings

Most participants were male and middle-aged, poly-drug users and socio-economically marginalized. While heroin users primarily originated from Africa, they reported significantly more criminal histories, drug (e.g. injection) and sex-risk behaviors and elevated rates of BBV (e.g. Hepatitis C Virus and HIV). A minority of heroin users attending the clinic was provided methadone treatment, mostly for detoxification.

Originality/value

This study documented information on a distinct sample of mostly migration-based heroin users in Sao Paulo, Brazil. Based on the local experience, global migration dynamics can bring changes to established drug use cultures and services, including new challenges for drug use-related related behaviors and therapeutic interventions that require effective understanding and addressing.

The relationship between crystal methamphetamine use and methadone retention in a prospective cohort of people who use drugs

BACKGROUND

The efficacy of methadone in reducing morbidity and mortality associated with opioid use disorder is supported by a wealth of evidence, yet methadone retention is often poor. While crystal methamphetamine (methamphetamine) use has been recently increasing in many countries, the effect of frequency of methamphetamine use on methadone discontinuation has not been investigated. We aimed to examine whether frequency of methamphetamine use is associated with increased rates of methadone discontinuation among individuals on methadone.

DESIGN

Two harmonized ongoing open prospective cohort studies of community-recruited people who use illicit drugs with semi-annual follow-ups between 2014 and 2018.

SETTING

Vancouver, Canada.

PARTICIPANTS

A community recruited sample of people who use drugs.

INTERVENTION

A time-varying variable of self-reported methamphetamine use frequency within the past six months.

MEASUREMENTS

The primary outcome was time to discontinuation of methadone, defined as reporting not being on methadone at the time of a follow-up interview during the study period. We employed multivariable extended Cox regression analysis to examine the relationship between frequency of methamphetamine use and time to methadone discontinuation after adjusting for potential confounders.

FINDINGS

Of 875 eligible participants who contributed 2319 person-years of follow-up, 284 (32.5 %) discontinued methadone at least once during follow-up and 135 (15.4 %) reported more than weekly methamphetamine use at study baseline. In a multivariate analysis, in comparison to no use, ≥weekly use of methamphetamine remained independently associated with methadone discontinuation (adjusted hazard ratio [aHR] = 1.38, 95 % CI = 1.03-1.85).

CONCLUSIONS

A significant proportion of participants on methadone in this study reported more than weekly crystal methamphetamine use, which was associated with an increased risk of methadone discontinuation. Closer follow up, education, and treatment of methamphetamine use may be needed for this group to improve methadone retention.

Structural competency in the post-prison period for people who inject drugs: A qualitative case study

INTRODUCTION

Access to services is key to successful community (re-)integration following release from prison. But many people experience disengagement from services, including people who inject drugs (PWID). We use a case study approach and the notion of structural competency to examine influences on access to services among a group of PWID recently released from prison.

METHODS

This qualitative study recruited participants from SuperMIX, (a longitudinal cohort study in Victoria, Australia).

INCLUSION CRITERIA

aged 18+; lifetime history of injecting drug use; incarcerated for > three months and released from custody < 12 months previously. From 48 participants, five case studies were selected as emblematic of the complex and intersecting factors occurring at the time participants missed an appointment at a service.

RESULTS

Numerous, concurrent, and interdependent structural influences in participants' lives coincided with their difficulty accessing and maintaining contact with services and resulted in missed appointments. The key factors involved in the cases presented here include policies around opioid agonist treatment, inadequate, unsuitable and unsafe housing, the management of mental health and side effects of treatment, the lack of social support or estrangement from family, and economic hardship. The support available from service workers to navigate these structural issues was inconsistent. One dissenting case is examined in which missing appointments is anticipated and accommodated.

CONCLUSIONS

A case study approach enabled a holistic and in-depth examination of upstream structural elements that intersect with limited social and economic resources to exacerbate the challenges of community re-entry. These results highlight structural issues that have a disproportionate impact on the choices and opportunities for PWID. The incorporation of a structural competency framework in design of services and in staff training could support person-centred and coordinated service provision that take into account PWID's experiences post-release to overcome structural barriers to service engagement.

The Role of Risk or Contributory Death Factors in Methadone-Related Fatalities: A Review and Pooled Analysis

Methadone-related deaths are characterized by a wide range of post-mortem blood concentrations, due to the high pharmacokinetic/dynamic inter-individual variability, the potential subjective tolerance state and to other risk factors or comorbidities, which might enhance methadone acute toxicity. In the present study, the association among pre-existing and external conditions and diseases and the resultant methadone death capacity have been investigated. Beside a systematic literature review, a retrospective case-control study was done, dividing cases in which methadone was the only cause of death (controls), and those with associated clinical-circumstantial (naive/non-tolerant state), pathological (pulmonary or cardiovascular diseases) or toxicological (other drugs detected) conditions. Methadone concentrations were compared between the two groups and the association with conditions/diseases was assessed by multiple linear and binomial logistic regressions. Literature cases were 139, in house 35, consisting of 22 controls and 152 cases with associated conditions/diseases. Mean methadone concentrations were 2122 ng/mL and 715 ng/mL in controls and cases respectively, with a statistically significant difference (p < 0.05). Lower methadone concentrations (by 24, 19 and 33% respectively) were detected in association with naive/non-tolerant state, pulmonary diseases and presence of other drugs, and low levels of methadone (<600 ng/mL) might lead to death in the presence of the above conditions/diseases.

Cost and cost-effectiveness of interim methadone treatment and patient navigation initiated in jail

BACKGROUND

Individuals with opioid use disorder (OUD) who are released from pre-trial detention in jail have a high risk of opioid relapse. While several interventions for OUD initiated during incarceration have been studied, few have had an economic evaluation. As part of a three-group randomized trial, we estimated the cost and cost-effectiveness of a negative urine opioid test. Detainees were assigned to interim methadone (IM) in jail with continued methadone treatment post-release with and without 3 months of post-release patient navigation (PN) compared to an enhanced treatment-as-usual group.

METHODS

We implemented a micro-costing approach from the provider's perspective to estimate the cost per participant in jail and over the 12 months post-release from jail. Economic data included jail-based and community-based service utilization, self-reported healthcare utilization and justice system involvement, and administrative arrest records. Our outcome measure is the number of participants with a negative opioid urine test at their 12-month follow-up. We calculated incremental cost-effectiveness ratios (ICERs) for intervention costs only and costs from a societal perspective.

RESULTS

The average cost of providing patient navigation services per individual beginning in jail and continuing in the community was $283. We find that IM is dominated by ETAU and IM + PN. Per additional participant with a negative opioid urine test, the ICER for IM + PN including intervention costs only is $91 and $305 including societal costs.

CONCLUSIONS

IM + PN is almost certainly the cost-effective choice from both an intervention provider and societal perspective.

Barriers to Medications for Opioid Use Disorder Among Veterans Involved in the Legal System: a Qualitative Study

BACKGROUND

Veterans involved in the legal system are at high risk for overdose but have lower receipt of medications for opioid use disorder than other veterans.

OBJECTIVE

The study aimed to understand barriers to medication access from the perspective of legally involved veterans with opioid use disorder and people who work with these veterans in the Veterans Health Administration (VHA) and the legal system.

DESIGN

This national qualitative study interviewed veterans and stakeholders from 14 geographically diverse VHA facilities to explore perceptions of barriers to medications for opioid use disorder.

PARTICIPANTS

Participants included veterans with a history of opioid use disorder and legal involvement (n = 18), VHA Veterans Justice Programs Specialists (n = 15), VHA and community substance use disorder treatment providers (n = 5), and criminal justice staff (n = 12).

APPROACH

We conducted interviews based on the Consolidated Framework for Implementation Research. Interview transcripts were analyzed using a team-based approach.

KEY RESULTS

Four key barriers, noted by group, were identified: (1) a preference for counseling along with or instead of medications (veterans, Specialists, treatment providers, criminal justice staff); (2) concerns about veterans using medications without a prescription, selling them, or providing them to others (veterans, Specialists, treatment providers, criminal justice staff); (3) concerns about perceived stigma towards medication use (veterans, Specialists, treatment providers, criminal justice staff); and (4) concerns about medication discontinuation after recurrent opioid use (veterans, criminal justice staff). A fifth theme, education, was noted by all stakeholders except providers as important to facilitating use of medications for opioid use disorder. All five themes mapped to the framework construct of knowledge and beliefs about the intervention.

CONCLUSIONS

Based on identified barriers, interventions focused on enhancing medication knowledge, reducing stigma towards use of medications, and increasing knowledge that opioid use may recur during treatment may help increase access to medication for veterans with legal involvement.

Impact of a jail-based treatment decision-making intervention on post-release initiation of medications for opioid use disorder

INTRODUCTION

Opioid use disorder (OUD) is common among people in jail and is effectively treated with medications for OUD (MOUD). People with OUD may have an incomplete or inaccurate understanding of OUD and MOUD, and of how to access care. We evaluated an OUD treatment decision making (TDM) intervention to determine whether the intervention increased MOUD initiation post-release.

METHODS

We conducted an observational retrospective cohort study of the TDM intervention on initiation of MOUD, individuals with records data indicating confirmed or suspected OUD incarcerated in four eligible jails were eligible to receive the intervention. Time-to-event analyses of the TDM intervention were conducted using Cox proportional hazard modeling with MOUD as the outcome.

RESULTS

Cox proportional hazard modeling, with the intervention modeled as having a time-varying effect due to violation of the proportionality assumption, indicated that those receiving the TDM intervention (n = 568) were significantly more likely to initiate MOUD during the first month after release from jail (adjusted hazard ratio 6.27, 95 % C.I. 4.20-9.37), but not in subsequent months (AHR 1.33 95 % C.I. 0.94-1.89), adjusting for demographics, prior MOUD, or felony or gross misdemeanor arrest in the prior year compared to those not receiving the intervention (n = 3174).

CONCLUSION

The TDM intervention was associated with a significantly higher relative hazard of starting MOUD, specifically during the first month after incarceration. However, a minority of all eligible people received any MOUD. Future research should examine ways to increase initiation on MOUD immediately after (or ideally during) incarceration.

The Mortality After Release from Incarceration Consortium (MARIC): Protocol for a multi-national, individual participant data meta-analysis

INTRODUCTION

More than 30 million adults are released from incarceration globally each year. Many experience complex physical and mental health problems, and are at markedly increased risk of preventable mortality. Despite this, evidence regarding the global epidemiology of mortality following release from incarceration is insufficient to inform the development of targeted, evidence-based responses. Many previous studies have suffered from inadequate power and poor precision, and even large studies have limited capacity to disaggregate data by specific causes of death, sub-populations or time since release to answer questions of clinical and public health relevance.

OBJECTIVES

To comprehensively document the incidence, timing, causes and risk factors for mortality in adults released from prison.

METHODS

We created the Mortality After Release from Incarceration Consortium (MARIC), a multi-disciplinary collaboration representing 29 cohorts of adults who have experienced incarceration from 11 countries. Findings across cohorts will be analysed using a two-step, individual participant data meta-analysis methodology.

RESULTS

The combined sample includes 1,337,993 individuals (89% male), with 75,795 deaths recorded over 9,191,393 person-years of follow-up.

CONCLUSIONS

The consortium represents an important advancement in the field, bringing international attention to this problem. It will provide internationally relevant evidence to guide policymakers and clinicians in reducing preventable deaths in this marginalized population.

Prevalence of Opioid Dependence and Opioid Agonist Treatment in the Berlin Custodial Setting: A Cross-Sectional Study

BACKGROUND

Among people living in detention, substance use is highly prevalent, including opioid dependence. Opioid agonist treatment (OAT) has been established as an evidence-based, first-line treatment for opioid dependence. Despite high prevalence of opioid dependence, conclusive data regarding its prevalence and the OAT practice in German prisons is scarce; rather, the existing data widely diverges concerning the rates of people in detention receiving OAT.

MATERIALS AND METHODS

We conducted a cross-sectional survey of all detention facilities in Berlin. On the date of data collection, a full census of the routine records was completed based on the medical documentation system. For each opioid dependent individual, we extracted sociodemographic data (i.e., age, sex, and non-/German nationality, whether people experienced language-related communication barriers), information about OAT, comorbidities (HIV, hepatitis C, schizophrenia), and the detention center, as well as the anticipated imprisonment duration and sentence type. The data was first analyzed descriptively and secondly in an evaluative-analytical manner by analyzing factors that influence the access to OAT of people living in detention.

RESULTS

Among the 4,038 people in detention in the Berlin custodial setting under investigation, we identified a 16% prevalence of opioid dependence. Of the opioid-dependent individuals, 42% received OAT; 31% were treated with methadone, 55% were treated with levomethadone, and 14% were treated with buprenorphine. Access to OAT seemed mainly dependent upon initial receipt of OAT at the time of imprisonment, detention duration, the prisons in which individuals were detained, German nationality, and sex. The overall prevalence of HIV was 4-8%, hepatitis C was 31-42%, and schizophrenia was 5%.

CONCLUSIONS

The prevalence of opioid dependence and access to OAT remains a major health issue in the custodial setting. OAT implementation must be especially intensified among male, non-German, opioid-dependent individuals with a short detention period. Treatment itself must be diversified regarding the substances used for OAT, and institutional treatment differences suggest the need for a consistent treatment approach and the standardized implementation of treatment guidelines within local prison's standard operating procedures. Testing for infectious diseases should be intensified among opioid-dependent people living in detention to address scarcely known infection statuses and high infection rates.

The Accessibility of Opioid Agonist Treatment and Its Forced Discontinuation in Swiss Prisons-Attitudes, Perceptions and Experiences of Defense Lawyers in Dealing With Detained Persons Using Opioids

BACKGROUND

Opioid agonist treatment (OAT) is an important pillar in the treatment of individuals using opioids and its continuation during imprisonment is recommended. Despite this knowledge access to and continuation of OAT is still limited in many countries. The forced discontinuation during pre-trial detention can cause severe withdrawal symptoms, which in turn may significantly impair the defendant's ability to exercise granted procedural participation rights. Furthermore, it can be argued that forced discontinuation of a desired treatment represents a form of a compulsory intervention.

AIMS

The present study was developed against the backdrop of a recent ruling by the European Court of Human Rights (Wenner vs. Germany). It intended to examine how defense lawyers dealing with detained persons using opioids view and assess the accessibility of OAT in pre-trial detention as well as during imprisonment in different parts of Switzerland.

METHODS

Using a qualitative approach, we interviewed 11 defense lawyers from three different cantons of Switzerland with multiple years of experience in providing legal representation to more than 220 defendants using heroin. The interviews were analyzed with QSR NVIVO 11 for Windows. A qualitative content analysis approach was used to evaluate findings.

RESULTS

Defenders who had been exposed to the opioid crisis during the course of their legal career had adopted a positive attitude towards OAT and associated it with a stabilizing influence on their clients, an improvement in criminal prognosis, and a reduction in recidivism. They were generally of the opinion that access to OAT had improved, however identified a considerable variance in different penitentiaries, which were mediated by attitudes of staff and authorities. Based on the assessments of the defense lawyers, it can be estimated that the initiation of OAT especially during pre-trial detention is challenging. The predominant aim of OAT in a variety of Swiss prisons still seems to focus on a discontinuation, mediated by a forced reduction of medication. Some of the interventions reported are not in line with the principle of equivalence and strongly contrast the recommendations of the Council of Europe.

Interventions for female drug-using offenders

BACKGROUND

This review represents one in a family of three reviews focusing on the effectiveness of interventions in reducing drug use and criminal activity for offenders.

OBJECTIVES

To assess the effectiveness of interventions for female drug-using offenders in reducing criminal activity, or drug use, or both.

SEARCH METHODS

We searched 12 electronic bibliographic databases up to February 2019.

SELECTION CRITERIA

We included randomised controlled trials (RCTs).

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane.

MAIN RESULTS

We included 13 trials with 2560 participants. Interventions were delivered in prison (7/13 studies, 53%) and community (6/13 studies, 47%) settings. The rating of bias was affected by the lack of clear reporting by authors, and we rated many items as 'unclear'. In two studies (190 participants) collaborative case management in comparison to treatment as usual did not reduce drug use (risk ratio (RR) 0.65, 95% confidence interval (CI) 0.20 to 2.12; 1 study, 77 participants; low-certainty evidence), reincarceration at nine months (RR 0.71, 95% CI 0.32 to 1.57; 1 study, 77 participants; low-certainty evidence), and number of subsequent arrests at 12 months (RR 1.11, 95% CI 0.83 to 1.49; 1 study, 113 participants; low-certainty evidence). One study (36 participants) comparing buprenorphine to placebo showed no significant reduction in self-reported drug use at end of treatment (RR 0.57, 95% CI 0.27 to 1.20) and three months (RR 0.58, 95% CI 0.25 to 1.35); very low-certainty evidence. No adverse events were reported. One study (38 participants) comparing interpersonal psychotherapy to a psychoeducational intervention did not find reduction in drug use at three months (RR 0.67, 95% CI 0.30 to 1.50; low-certainty evidence). One study (31 participants) comparing acceptance and commitment therapy (ACT) to a waiting list showed no significant reduction in self-reported drug use using the Addiction Severity Index (mean difference (MD) -0.04, 95% CI -0.37 to 0.29) and abstinence from drug use at six months (RR 2.89, 95% CI 0.73 to 11.43); low-certainty evidence. One study (314 participants) comparing cognitive behavioural skills to a therapeutic community programme and aftercare showed no significant reduction in self-reported drug use (RR 0.86, 95% CI 0.58 to 1.27), re-arrest for any type of crime (RR 0.73, 95% CI 0.52 to 1.03); criminal activity (RR 0.80, 95% CI 0.63 to 1.03), or drug-related crime (RR 0.95, 95% CI 0.68 to 1.32). A significant reduction for arrested (not for parole) violations at six months follow-up was significantly in favour of cognitive behavioural skills (RR 0.43, 95% CI 0.25 to 0.77; very low-certainty evidence). A second study with 115 participants comparing cognitive behavioural skills to an alternative substance abuse treatment showed no significant reduction in reincarceration at 12 months (RR 0.70, 95% CI 0.43 to 1.12; low certainty-evidence. One study (44 participants) comparing cognitive behavioural skills and standard therapy versus treatment as usual showed no significant reduction in Addiction Severity Index (ASI) drug score at three months (MD 0.02, 95% CI -0.05 to 0.09) and six months (MD -0.02, 95% CI -0.09 to 0.05), and incarceration at three months (RR 0.46, 95% CI 0.04 to 4.68) and six months (RR 0.51, 95% CI 0.20 to 1.27); very low-certainty evidence. One study (171 participants) comparing a single computerised intervention versus case management showed no significant reduction in the number of days not using drugs at three months (MD -0.89, 95% CI -4.83 to 3.05; low certainty-evidence). One study (116 participants) comparing dialectic behavioural therapy and case management (DBT-CM) versus a health promotion intervention showed no significant reduction at six months follow-up in positive drug testing (RR 0.67, 95% CI 0.43 to 1.03), number of people not using marijuana (RR 1.23, 95% CI 0.95 to 1.59), crack (RR 1.00, 95% CI 0.87 to 1.14), cocaine (RR 1.02, 95% CI 0.93 to 1.12), heroin (RR 1.05, 95% CI 0.98 to 1.13), methamphetamine (RR 1.02, 95% CI 0.87 to 1.20), and self-reported drug use for any drug (RR 1.20, 95% CI 0.92 to 1.56); very low-certainty evidence. One study (211 participants) comparing a therapeutic community programme versus work release showed no significant reduction in marijuana use at six months (RR 1.03, 95% CI 0.19 to 5.65), nor 18 months (RR 1.00, 95% CI 0.07 to 14.45), heroin use at six months (RR 1.59, 95% CI 0.49 to 5.14), nor 18 months (RR 1.92, 95% CI 0.24 to 15.37), crack use at six months (RR 2.07, 95% CI 0.41 to 10.41), nor 18 months (RR 1.64, 95% CI 0.19 to 14.06), cocaine use at six months (RR 1.09, 95% CI 0.79 to 1.50), nor 18 months (RR 0.93, 95% CI 0.64 to 1.35). It also showed no significant reduction in incarceration for drug offences at 18 months (RR 1.45, 95% CI 0.87 to 2.42); with overall very low- to low-certainty evidence. One study (511 participants) comparing intensive discharge planning and case management versus prison only showed no significant reduction in use of marijuana (RR 0.79, 95% CI 0.53 to 1.16), hard drugs (RR 1.12, 95% CI 0.88 to 1.43), crack cocaine (RR 1.08, 95% CI 0.75 to 1.54), nor positive hair testing for marijuana (RR 0.75, 95% CI 0.55 to 1.03); it found a significant reduction in arrests (RR 0.19, 95% CI 0.04 to 0.87), but no significant reduction in drug charges (RR 1.07, 95% CI 0.75 to 1.53) nor incarceration (RR 1.09, 95% CI 0.86 to 1.39); moderate-certainty evidence. One narrative study summary (211 participants) comparing buprenorphine pre- and post-release from prison showed no significant reduction in drug use at 12 months post-release; low certainty-evidence. No adverse effects were reported.

AUTHORS' CONCLUSIONS

The studies showed a high degree of heterogeneity for types of comparisons, outcome measures and small samples. Descriptions of treatment modalities are required. On one outcome of arrest (no parole violations), we identified a significant reduction when cognitive behavioural therapy (CBT) was compared to a therapeutic community programme. But for all other outcomes, none of the interventions were effective. Larger trials are required to increase the precision of confidence about the certainty of evidence.

Longitudinal analysis of HIV-risk behaviors of participants in a randomized trial of prison-initiated buprenorphine

Background

It has been estimated that approximately 15% of people who are incarcerated in the US have histories of opioid use disorder. Relapse to opioid use after release from prison poses a serious risk of HIV infection. Prison-initiated buprenorphine may help to reduce HIV infection given the association between opioid use and HIV-risk behaviors.

Methods

The present study is a secondary analysis of longitudinal data gathered from a randomized controlled trial of buprenorphine-naloxone for people who were incarcerated (N = 211) between 2008 and 2012. It compares the impact of assignment to initiate buprenorphine in prison (N = 106 randomized, N = 104 analyzed) versus in the community (N = 107 randomized, N = 107 analyzed) and whether or not participants entered community treatment on the frequency of HIV-risk behaviors in the 12 months following release from prison. Data were analyzed hierarchically and for each outcome variable, a multilevel, over-dispersed Poisson model was fit to the data. Outcome variables were the number of times the following behaviors occurred in the last 30 days: (1) having sex without a condom (2) injecting drugs (3) using unsterilized needles, and (4) sharing injection paraphernalia.

Results

Participants assigned to begin buprenorphine in the community experienced a greater decrease in injection drug use over time compared to participants assigned to begin buprenorphine in prison. There were no significant associations between treatment assignment or community treatment entry and instances of having sex without a condom, sharing injection paraphernalia, or using unsterilized needles.

Conclusions

Overall, the present study did not find support for the initiation of buprenorphine in prison (as opposed to the community) as a means to reduce incidences of HIV-risk behaviors. Avenues for future research in the nexus of HIV-risk reduction, criminal justice, and pharmacotherapy are discussed.

Trial registration This study was supported by the National Institute on Drug Abuse (NIDA), Buprenorphine for Prisoners (PI: Kinlock; R01DA021579). ClinicalTrials.gov identifier: NCT 00574067

Association between methamphetamine use and retention among patients with opioid use disorders treated with buprenorphine

BACKGROUND

Methamphetamine use is increasing in parts of the U.S., yet its impact on treatment for opioid use disorder is relatively unknown.

METHODS

The study utilized data on adult patients receiving buprenorphine from Washington State Medication Assisted Treatment-Prescription Drug and Opioid Addiction program clinics between November 1, 2015 and April 31, 2018. Past 30-day substance use data were collected at baseline and 6-months, as well as date of program discharge. Cox proportional hazards regression was used to estimate the relative hazards for treatment discharge comparing methamphetamine users at baseline with non-users, adjusting for site, time period, age, gender, race, ethnicity, and education. For a subset of patients with data, we describe the proportion of individuals reporting methamphetamine use at baseline versus 6-months.

RESULTS

The sample included 799 patients, of which 237 (30%) reported using methamphetamine in the past 30 days; of those, 156 (66%) reported 1-10 days of use, 46 (19%) reported 11-20 days of use, and 35 (15%) reported 21-30 days of use. Baseline methamphetamine use was associated with more than twice the relative hazards for discharge in adjusted models (aHR = 2.39; 95% CI: 1.94-2.93). In the sub-sample with data (n = 516), there was an absolute reduction of 15% in methamphetamine use: 135 (26%) reported use at baseline versus 57 (11%) at follow-up.

CONCLUSIONS

In summary, this study found that patients who concurrently used methamphetamine were less likely to be retained in buprenorphine treatment compared to non-users. For persons who were retained, however, methamphetamine use decreased over time.

Improved Health Outcomes from Hepatitis C Treatment Scale-Up in Spain's Prisons: A Cost-Effectiveness Study

Hepatitis C virus (HCV) is 15 times more prevalent among persons in Spain's prisons than in the community. Recently, Spain initiated a pilot program, JAILFREE-C, to treat HCV in prisons using direct-acting antivirals (DAAs). Our aim was to identify a cost-effective strategy to scale-up HCV treatment in all prisons. Using a validated agent-based model, we simulated the HCV landscape in Spain's prisons considering disease transmission, screening, treatment, and prison-community dynamics. Costs and disease outcomes under status quo were compared with strategies to scale-up treatment in prisons considering prioritization (HCV fibrosis stage vs. HCV prevalence of prisons), treatment capacity (2,000/year vs. unlimited) and treatment initiation based on sentence lengths (>6 months vs. any). Scaling-up treatment by treating all incarcerated persons irrespective of their sentence length provided maximum health benefits-preventing 10,200 new cases of HCV, and 8,300 HCV-related deaths between 2019-2050; 90% deaths prevented would have occurred in the community. Compared with status quo, this strategy increased quality-adjusted life year (QALYs) by 69,700 and costs by €670 million, yielding an incremental cost-effectiveness ratio of €9,600/QALY. Scaling-up HCV treatment with DAAs for the entire Spanish prison population, irrespective of sentence length, is cost-effective and would reduce HCV burden.

Interventions for drug-using offenders with co-occurring mental health problems

BACKGROUND

This review represents one from a family of three reviews focusing on interventions for drug-using offenders. Many people under the care of the criminal justice system have co-occurring mental health problems and drug misuse problems; it is important to identify the most effective treatments for this vulnerable population.

OBJECTIVES

To assess the effectiveness of interventions for drug-using offenders with co-occurring mental health problems in reducing criminal activity or drug use, or both.This review addresses the following questions.• Does any treatment for drug-using offenders with co-occurring mental health problems reduce drug use?• Does any treatment for drug-using offenders with co-occurring mental health problems reduce criminal activity?• Does the treatment setting (court, community, prison/secure establishment) affect intervention outcome(s)?• Does the type of treatment affect treatment outcome(s)?

SEARCH METHODS

We searched 12 databases up to February 2019 and checked the reference lists of included studies. We contacted experts in the field for further information.

SELECTION CRITERIA

We included randomised controlled trials designed to prevent relapse of drug use and/or criminal activity among drug-using offenders with co-occurring mental health problems.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures as expected by Cochrane .

MAIN RESULTS

We included 13 studies with a total of 2606 participants. Interventions were delivered in prison (eight studies; 61%), in court (two studies; 15%), in the community (two studies; 15%), or at a medium secure hospital (one study; 8%). Main sources of bias were unclear risk of selection bias and high risk of detection bias.Four studies compared a therapeutic community intervention versus (1) treatment as usual (two studies; 266 participants), providing moderate-certainty evidence that participants who received the intervention were less likely to be involved in subsequent criminal activity (risk ratio (RR) 0.67, 95% confidence interval (CI) 0.53 to 0.84) or returned to prison (RR 0.40, 95% CI 0.24 to 0.67); (2) a cognitive-behavioural therapy (one study; 314 participants), reporting no significant reduction in self-reported drug use (RR 0.78, 95% CI 0.46 to 1.32), re-arrest for any type of crime (RR 0.69, 95% CI 0.44 to 1.09), criminal activity (RR 0.74, 95% CI 0.52 to 1.05), or drug-related crime (RR 0.87, 95% CI 0.56 to 1.36), yielding low-certainty evidence; and (3) a waiting list control (one study; 478 participants), showing a significant reduction in return to prison for those people engaging in the therapeutic community (RR 0.60, 95% CI 0.46 to 0.79), providing moderate-certainty evidence.One study (235 participants) compared a mental health treatment court with an assertive case management model versus treatment as usual, showing no significant reduction at 12 months' follow-up on an Addictive Severity Index (ASI) self-report of drug use (mean difference (MD) 0.00, 95% CI -0.03 to 0.03), conviction for a new crime (RR 1.05, 95% CI 0.90 to 1.22), or re-incarceration to jail (RR 0.79, 95% CI 0.62 to 1.01), providing low-certainty evidence.Four studies compared motivational interviewing/mindfulness and cognitive skills with relaxation therapy (one study), a waiting list control (one study), or treatment as usual (two studies). In comparison to relaxation training, one study reported narrative information on marijuana use at three-month follow-up assessment. Researchers reported a main effect < .007 with participants in the motivational interviewing group, showing fewer problems than participants in the relaxation training group, with moderate-certainty evidence. In comparison to a waiting list control, one study reported no significant reduction in self-reported drug use based on the ASI (MD -0.04, 95% CI -0.37 to 0.29) and on abstinence from drug use (RR 2.89, 95% CI 0.73 to 11.43), presenting low-certainty evidence at six months (31 participants). In comparison to treatment as usual, two studies (with 40 participants) found no significant reduction in frequency of marijuana use at three months post release (MD -1.05, 95% CI -2.39 to 0.29) nor time to first arrest (MD 0.87, 95% CI -0.12 to 1.86), along with a small reduction in frequency of re-arrest (MD -0.66, 95% CI -1.31 to -0.01) up to 36 months, yielding low-certainty evidence; the other study with 80 participants found no significant reduction in positive drug screens at 12 months (MD -0.7, 95% CI -3.5 to 2.1), providing very low-certainty evidence.Two studies reported on the use of multi-systemic therapy involving juveniles and families versus treatment as usual and adolescent substance abuse therapy. In comparing treatment as usual, researchers found no significant reduction up to seven months in drug dependence on the Drug Use Disorders Identification Test (DUDIT) score (MD -0.22, 95% CI -2.51 to 2.07) nor in arrests (RR 0.97, 95% CI 0.70 to 1.36), providing low-certainty evidence (156 participants). In comparison to an adolescent substance abuse therapy, one study (112 participants) found significant reduction in re-arrests up to 24 months (MD 0.24, 95% CI 0.76 to 0.28), based on low-certainty evidence.One study (38 participants) reported on the use of interpersonal psychotherapy in comparison to a psychoeducational intervention. Investigators found no significant reduction in self-reported drug use at three months (RR 0.67, 95% CI 0.30 to 1.50), providing very low-certainty evidence. The final study (29 participants) compared legal defence service and wrap-around social work services versus legal defence service only and found no significant reductions in the number of new offences committed at 12 months (RR 0.64, 95% CI 0.07 to 6.01), yielding very low-certainty evidence.

AUTHORS' CONCLUSIONS

Therapeutic community interventions and mental health treatment courts may help people to reduce subsequent drug use and/or criminal activity. For other interventions such as interpersonal psychotherapy, multi-systemic therapy, legal defence wrap-around services, and motivational interviewing, the evidence is more uncertain. Studies showed a high degree of variation, warranting a degree of caution in interpreting the magnitude of effect and the direction of benefit for treatment outcomes.

Recidivism, health and social functioning following release to the community of NSW prisoners with problematic drug use: study protocol of the population-based retrospective cohort study on the evaluation of the Connections Program

INTRODUCTION

The rising rate of incarceration in Australia, driven by high reoffending, is a major public health problem. Problematic drug use is associated with increasing rates of reoffending and return to custody of individuals. Throughcare provides support to individuals during imprisonment through to post-release, improving both the transition to community and health outcomes post-incarceration. The aim of this study is to evaluate the Connections Programme (CP) that utilises a throughcare approach for release planning of people in prison with a history of problematic drug use. The study protocol is described.

METHODS AND ANALYSIS

Population-based retrospective cohort study. The study will use record linkage of the Connections dataset with 10 other New South Wales (NSW) population datasets on offending, health service utilisation, opioid substitution therapy, pregnancy, birth and mortality. The study includes all patients who were eligible to participate in the CP between January 2008 and December 2015 stratified by patients who were offered CP and eligible patients who were not offered the programme (non-CP (NCP)). Propensity-score matching will be used to appropriately adjust for the observable differences between CP and NCP. The differences between two groups will be examined using appropriate univariate and multivariate analyses. A generalised estimating equation approach, which can deal with repeat outcomes for individuals will be used to examine recidivism, mortality and other health outcomes, including perinatal and infant outcomes. Survival analysis techniques will be used to examine the effect of the CP by sex and Indigenous status on the 'time-to' health-related outcomes after adjusting for potential confounders.

ETHICS AND DISSEMINATION

Ethical approval was received from the NSW Population and Health Services Research Ethics Committee, the Justice Health and Forensic Mental Health Network Human Research Ethics Committee, the Aboriginal Health and Medical Research Council Ethics Committee, the Corrective Services NSW Ethics Committee and the University of Technology Sydney Human Research Ethics Committee.

The impact of drug court participation on mortality: 15-year outcomes from a randomized controlled trial

AIM

To test the effects of drug court participation on long-term mortality risk.

METHODS

During 1997-98, 235 individuals charged with a non-violent offense were randomly assigned to Baltimore City Drug Treatment Court (BCDTC) or traditional adjudication. Heroin was the predominant substance of choice among the sample. Participant mortality was observed for 15 years following randomization.

RESULTS

Over 20% of participants died during the study, at an average age of 46.6 years, and 64.4% of deaths were substance-use related. Survival analyses estimated that neither mortality from any cause nor from substance use-related causes significantly differed between BCDTC and traditional adjudication.

CONCLUSIONS

Frequent and premature death among the sample indicates that this is a high-risk population in need of effective substance use treatment. Roughly half of drug treatment courts are now estimated to offer medication assisted treatment (MAT), which is currently the most effective treatment for opioid use disorders. In this study of BCDTC implemented over 15 years ago, only 7% of participants received MAT, which may explain the lack of program impact on mortality. Historical barriers to providing MAT in drug court settings include access, concerns about diversion, negative attitudes, blanket prohibitions, and stigma. Drug treatment courts should implement best practice standards for substance use treatment and overdose prevention, including increased access to MAT and naloxone, and training to reduce stigmatizing language and practice.

Factors Correlating to the Development of Hepatitis C Virus Infection among Drug Users-Findings from a Systematic Review and Meta-Analysis

Hepatitis C remains a significant public health threat. However, the main routes of transmission have changed since the early 1990s. Currently, drug use is the main source of hepatitis C virus (HCV) infection, and some measures have been successively implemented and additional studies have been published. However, the factors correlating with HCV infection failed to clearly define. Our study pooled the odds ratios (ORs) with 95% confidence intervals (CIs) and analyzed sensitivity by searching data in the PubMed, Elsevier, Springer, Wiley, and EBSCO databases. Publication bias was determined by Egger's test. In our meta-analysis, HCV-infected and non-HCV-infected patients from 49 studies were analyzed. The pooled ORs with 95% CIs for study factors were as follows: Injecting drug use 10.11 (8.54, 11.97); sharing needles and syringes 2.24 (1.78, 2.83); duration of drug use >5 years 2.39 (1.54, 3.71); unemployment 1.50 (1.22, 1.85); commercial sexual behavior 1.00 (0.73, 1.38); married or cohabiting with a regular partner 0.88 (0.79, 0.98), and sexual behavior without a condom 1.72 (1.07, 2.78). This study found that drug users with histories of injecting drug use, sharing needles and syringes, drug use duration of >5 years, and unemployment, were at increased risk of HCV infection. Our findings indicate that sterile needles and syringes should be made available to ensure safe injection. In view of that, methadone maintenance treatment can reduce or put an end to risky drug-use behaviors, and should be scaled up further, thereby reducing HCV infection.

Factors Correlating to the Development of Hepatitis C Virus Infection in Hemodialysis Patients-Findings Mainly from Asiatic Populations: A Systematic Review and Meta-Analysis

Hemodialysis is an effective replacement therapy for chronic renal failure patients. In recent decades, the number of hemodialysis patients has grown rapidly and some measures for preventing blood-borne diseases have been implemented, but hepatitis C virus (HCV) infection remains a significant problem. The meta-analysis published in 2009 on HCV infection-related factors was based on localized study objects, and some additional studies have been published since 2009; however, the contribution of these factors remains under dispute. Our study pooled the odds ratios (ORs) or mean standard deviations (MDs) with 95% confidence intervals (CIs) and analyzed sensitivity using Review Manager 5.1 software (5.1 version Copenhagen: The Nordic Cochrane Centre; 2011) by searching data in the PubMed, Elsevier, Springer, Wiley, and EBSCO databases. Spearman correlation analysis was performed using the SPSS package. In our meta-analysis, 1715 HCV-infected hemodialysis patients and 7093 non-HCV-infected hemodialysis patients from 44 studies were analyzed. The pooled ORs with 95% CIs were: histories of blood transfusion, 4.30 (3.11, 5.96); weekly hemodialysis times > 2, 6.00 (3.25, 11.06); kidney transplantation, 5.80 (3.95, 8.52); hemodialysis units > 2, 6.90 (2.42, 19.68); shared hemodialysis devices, 5.00 (2.35, 10.65); and drug addiction, 4.73 (1.54, 14.47). The pooled MDs with 95% CIs were duration of hemodialysis (months) 27.48 (21.67, 33.30). There was a positive correlation between duration of hemodialysis and the HCV infection rate (p < 0.01). Hemodialysis patients, especially from Asia, with shared hemodialysis devices, hemodialysis units > 2, blood transfusion, kidney transplantation, and drug addiction were at increased risk of HCV infection. The HCV infection rate increased with the duration of hemodialysis. High-risk hemodialysis patients should be monitored and receive timely screening.

History of detention and the risk of hepatitis C among people who inject drugs in Germany

OBJECTIVES

The aim of this study was to investigate the association between detention experience and hepatitis C virus (HCV) status, the role of duration and frequency of detention, and whether risk behaviours practiced in detention could explain an observed increase in risk.

METHODS

Current drug injectors (injecting in the last 12 months) were recruited to participate in a sero-behavioural, cross-sectional survey using respondent-driven sampling in eight German cities during the years 2011-2014. Using multivariable logistic regression, the association between HCV status and reported detention experience was investigated.

RESULTS

A total of 1998 participants were included in the analysis. Of these, 19.9% reported no detention experience, 28.6% short and rare experience (≤3.5 years in total, ≤3 times), 12.1% short but frequent experience, 7.1% long but rare experience, and 32.4% long and frequent experience. After correcting for HCV risk factors, the association between detention experience and HCV status remained statistically significant. By adjusting the model for intramural risk behaviours, the odds ratios of detention experience were reduced but remained significant.

CONCLUSIONS

The proportion of people who inject drugs positive for HCV increased with both frequency and duration of their detention experience. As intramural risk behaviours could not fully explain this increase, it appears that transfers between community and custody may confer additional risks.

Effectiveness of medication assisted treatment for opioid use in prison and jail settings: A meta-analysis and systematic review

This study examined the state of the literature on the effectiveness of medication assisted treatment (MAT; methadone, buprenorphine, naltrexone) delivered in prisons and jails on community substance use treatment engagement, opioid use, recidivism, and health risk behaviors following release from incarceration. Randomized controlled trials (RCTs) and quasi-experimental studies published through December 2017 that examined induction to or maintenance on methadone (n = 18 studies), buprenorphine (n = 3 studies), or naltrexone (n = 3 studies) in correctional settings were identified from PsycINFO and PubMed databases. There were a sufficient number of methadone RCTs to meta-analyze; there were too few buprenorphine or naltrexone studies. All quasi-experimental studies were systematically reviewed. Data from RCTs involving 807 inmates (treatment n = 407, control n = 400) showed that methadone provided during incarceration increased community treatment engagement (n = 3 studies; OR = 8.69, 95% CI = 2.46; 30.75), reduced illicit opioid use (n = 4 studies; OR = 0.22, 95% CI = 0.15; 0.32) and injection drug use (n = 3 studies; OR = 0.26, 95% CI = 0.12; 0.56), but did not reduce recidivism (n = 4 studies; OR = 0.93, 95% CI = 0.51; 1.68). Data from observational studies of methadone showed consistent findings. Individual review of buprenorphine and naltrexone studies showed these medications were either superior to methadone or to placebo, or were as effective as methadone in reducing illicit opioid use post-release. Results provide the first meta-analytic summary of MATs delivered in correctional settings and support the use of MATs, especially with regard to community substance use treatment engagement and opioid use; additional work is needed to understand the reduction of recidivism and other health risk behaviors.

Context-induced relapse after extinction versus punishment: similarities and differences

Results from clinical studies suggest that drug relapse and craving are often provoked by exposure to drug-associated contexts. Since 2002, this phenomenon has been modeled in laboratory animals using the ABA renewal model. In the classical version of this model, rats with a history of drug self-administration in one context (A) undergo extinction in a different context (B) and reinstate (or relapse to) drug seeking after exposure to the original drug-associated context (A). In a more recent version of the model introduced in 2013, the experimental conditions in context A are identical to those used in the classical model, but drug-reinforced responding in context B is suppressed by probabilistic punishment. The punishment-based ABA renewal model is proposed to resemble abstinence in humans, which is often initiated by the desire to avoid the negative consequences of drug use. The goal of our review is to discuss similarities and differences in mechanisms that play a role in suppression of drug seeking in context B and context-induced relapse to drug seeking in context A in the two models. We first describe psychological mechanisms that mediate extinction and punishment of drug-reinforced responding in context B. We then summarize recent findings on brain mechanisms of context-induced relapse of drug seeking after extinction, or punishment-imposed abstinence. These findings demonstrate both similarities and differences in brain mechanisms underlying relapse in the two variations of the ABA renewal model. We conclude by briefly discussing clinical implications of the preclinical studies.

Methadone Maintenance Treatment: A 15-year Retrospective Study in Split-Dalmatia County, Croatia

BACKGROUND

The aim of this retrospective study is to use existing epidemiological data on patients in methadone maintenance treatment in Split-Dalmatia County from 2001 to 2015 to evaluate the substitution treatment system and policy of opiate addicts treatment, the epidemiological trend, and risk of overdose mortality. In addition, we would like to highlight the problem of poor control of methadone therapy and thus the possibility of selling methadone. The result is a greater number of deaths caused by methadone in people who were not in methadone therapy.

METHODS

The research included data collected from 3189 patients who had been in the drug abuse treatment program in Split-Dalmatia County during 2001-2015 and data gathered from autopsy examinations of patients in Split-Dalmatia County with emphasis on data for 186 overdosed patients during research period.

RESULTS

The total number of patients in the methadone treatment program in Split-Dalmatia County during the research period, except in 2005 and 2006, has been stable, while the number of new opiate patients, being in first-time treatment, decreased by 62.5%. The number of addicts who were in a long-term maintenance program has increased by 198%, whereas the number of addicts who were in a short-term detoxification treatment has decreased by 96.4%. According to results obtained from performed autopsies, 186 death cases were determined as overdoses. Methadone was found in 56 of those cases and was declared as the cause of death in 39 cases (70%). Of the total number of autopsied patients with diagnosed methadone overdose, only 23 (59%) had been recorded to receive methadone therapy in Public Health Institute of Split-Dalmatia County database.

CONCLUSIONS

The results of this study show the favorable epidemiological trend because of the decreasing number of new opiate patients in treatment. The retention of opiate patients in substitution therapy indicates the effectiveness of methadone maintenance programs. Our research did not determine any influence of methadone substitution therapy on an increasing risk of specific (overdose) mortality.

Utilization of opioid agonist therapy among incarcerated persons with opioid use disorder in Vancouver, Canada

BACKGROUND

Inability to access opioid agonist therapy (OAT) in correctional settings has previously been reported in Vancouver, Canada, and is associated with harms among people with opioid use disorder (OUD), including overdose death. We investigated the prevalence and correlates of OAT utilization within correctional settings among incarcerated persons with OUD in Vancouver.

METHODS

Data were derived from three prospective cohorts of people who use drugs in Vancouver between 2005 and 2016. Using multivariable generalized estimating equations, we examined factors associated with OAT utilization among participants with OUD reporting incarceration in the past six months.

RESULTS

Among 597 eligible participants, 207 (34.7%) contributed 325 reports of having utilized OAT while incarcerated. Of those, 295 (90.8%) were continuations and 30 (9.2%) were new initiations of OAT while incarcerated. For those currently on OAT (at the time of interview), in multivariable analyses, non-fatal overdose (adjusted odds ratio [AOR] = 0.49, 95% confidence interval [CI]: 0.29-0.82) and daily prescription opioid use (AOR = 0.42, 95% CI: 0.20-0.85) remained independently and negatively associated with having utilized OAT while incarcerated. For those not currently on OAT, none of the variables considered had significant associations with utilization of OAT while incarcerated.

CONCLUSIONS

Utilization of OAT in correctional settings was low in our sample. Utilization of OAT was significantly and negatively associated with overdose and ongoing prescription opioid misuse if OAT was continued upon release from correctional settings. Findings underscore the urgent need for improved utilization of OAT in correctional settings, and linkage to community care to prevent harms such as overdose.

Hepatitis C infection and psychiatric burden in two imprisoned cohorts: Young offenders and opioid-maintained prisoners

Prisoners constitute a considerable gap in the hepatitis C virus (HCV) tested population. The present study examined HCV prevalence in imprisoned opioid-maintained patients (OMT-P) and adolescents and young adults (AYA, 14-26 years). In addition, HCV testing and treatment provision, knowledge of HCV status and psychiatric comorbidity were assessed. Data collection took place in six Austrian prisons. Participants were N = 133 for OMT-P (78% male, mean age 35.7 years) and N = 71 for AYA (100% male, mean age 19.8 years). Analysis of HCV serology was conducted. Psychiatric comorbidity and addiction severity were assessed applying standardized questionnaires and interviews. Antibodies were detected in 74.4% of OMT-P, and in 45.0% HCV infection was confirmed. Only one AYA was infected with HCV. None of the participants was receiving treatment for HCV. Eleven percent of OMT-P (50.7% of AYA) did not know their HCV status, and 14.3% of OMT-P (36.6% of AYA) had not been tested in prison. Among OMT-P, lifetime IDU [OR = 330.33, CI = 25.91-4433.20] and age at first IDU [OR = 0.90, CI = 0.82-0.98] significantly predicted HCV status. In both samples, a high prevalence of affective disorders was observed. Despite the high prevalence of HCV among opioid-dependent detainees, the unique opportunities for comprehensive testing and treatment of HCV are substantially underutilized. This is in stark contrast to the UN Basic Principles for the Treatment of Prisoners.

Pharmacotherapy for opioid addiction in community corrections

Pharmacotherapy for opioid addiction with methadone, buprenorphine, and naltrexone has proven efficacy in reducing illicit opioid use. These treatments are under-utilized among opioid-addicted individuals on parole, probation, or in drug courts. This paper examines the peer-reviewed literature on the effectiveness of pharmacotherapy for opioid addiction of adults under community-based criminal justice supervision in the US. Compared to general populations, there are relatively few papers addressing the separate impact of pharmacotherapy on individuals under community supervision. Tentative conclusions can be drawn from the extant literature. Reasonable evidence exists that illicit opioid use and self-reported criminal behaviour decline after treatment entry, and that these outcomes are as favourable among individuals under criminal justice supervision as the general treatment population. Surprisingly, there is no conclusive evidence regarding the extent to which pharmacotherapy impacts the likelihood of arrest and incarceration among individuals under supervision. However, given the proven efficacy of these three medications in reducing illicit opioid use and the evidence that, in the general population, methadone and buprenorphine treatment are associated with reduction in overdose mortality, the use of all three pharmacotherapies among patients under criminal justice supervision should be expanded while more data are collected on their impact on arrest and incarceration.

The feasibility of following up prisoners, with mental health problems, after release: a pilot trial employing an innovative system, for engagement and retention in research, with a harder-to-engage population

Background

Following up released prisoners is demanding, particularly for those prisoners with mental health problems, for whom stigma and chaotic lifestyles are problematic. Measurement of mental health outcomes after release is challenging. To evaluate mental healthcare for offender populations, using high-quality randomised controlled trials, evidenced-based methods must be developed to engage them while in custody, to locate and re-interview them after release, and to collect potentially stigmatising mental health outcomes data.

Methods

We developed an initial theoretical model and operational procedures for collecting baseline and follow-up data informed by a literature search, focus groups, and case studies. Male prisoners from five prisons in two sites were invited to participate. The inclusion criteria included individuals who were above threshold on nine-item Patient Health Questionnaire, seven-item Generalized Anxiety Disorder, or post-traumatic stress disorder scales, or who had reported mental health problems in the past 2 years or had been assessed with a likely personality disorder. Potential participants were interviewed to generate baseline data and were re-contacted before their release. We then contacted them for a follow-up interview, which included repeating the earlier data collection measures 2–8 weeks after release. A qualitative formative process evaluation produced and refined a model procedure for the recruitment and retention of male prison leavers in trials, identified the mechanisms which promoted engagement and retention, and mapped these against a theoretical behaviour change model.

Results

We developed a flexible procedure which was successful in recruiting male prison leavers to a pilot trial: 185/243 (76%, 95% confidence interval (CI) 70–81%) of those approached agreed to participate. We also retained 63% (95% CI 54–71%) of those eligible to participate in a follow-up interview 2–8 weeks after release. Mental health outcomes data was collected at both these time points.

Conclusions

It is possible to design acceptable procedures to achieve sustained engagement critical for delivering and evaluating interventions in prison and in the community and to collect mental health outcomes data. These procedures may reduce attrition bias in future randomised controlled trials of mental health interventions for prison leavers. This procedure has been replicated and successfully delivered in a subsequent pilot trial and a definitive randomised controlled trial.

Initiating buprenorphine treatment prior to versus after release from prison: Arrest outcomes

BACKGROUND

This secondary analysis of a randomized trial examines the association between initiation of buprenorphine treatment prior to, versus post-release, and rearrests during the 12-months following release.

METHODS

Official rearrest data (N = 199) for the 12-months post-release were examined. Four outcomes were measured: (1) rearrested (yes/no), (2) time to rearrest, (3) number of rearrests, and (4) severity of charges (less severe vs. severe).

RESULTS

A minority (43.1%) of the sample were rearrested (N = 91). There were no significant differences between study conditions in the proportion of rearrested participants [P = 0.28] nor in the mean number of arrests [P  = 0.15]. Likewise, the condition was not a significant predictor of the hazard of rearrest [p = 0.10]. The mean number of days until rearrest for the in prison vs. post-release buprenorphine conditions were not significantly different (205.8 days (SD  = 104.6) vs. 170.8 days (SD  = 113.1), respectively; P  = 0.13]. Treatment condition was not a significant predictor of the likelihood of rearrest for a severe crime compared to a less severe crime [P  = 0.09].

CONCLUSION

Despite the parent study finding of higher rates of post-release drug treatment entry in the group assigned to start buprenorphine treatment prior to, compared to post-release, there were no significant differences in the proportion of individuals arrested, the mean number of arrests, the time to first arrest, or the severity of their charges.

Our Ethical Obligation to Treat Opioid Use Disorder in Prisons: A Patient and Physician's Perspective

The opioid epidemic has claimed the lives of more than 183,000 individuals since 1999 and is now the leading cause of accidental death in the United States. Meanwhile, rates of incarceration have quadrupled in recent decades, and drug use is the leading cause of incarceration. Medication-assisted treatment or MAT (i.e. methadone, buprenorphine) is the gold standard for treatment of opioid use disorder. Incarcerated individuals with opioid use disorder treated with methadone or buprenorphine have a lower risk of overdose, lower rates of hepatitis C transmission, and lower rates of re-incarceration. Despite evidence of improved outcomes, many jails and prisons do not offer MAT to individuals with opioid use disorder. This seems partly due to a scientifically unjustified preference for an abstinence-only treatment approach. The absence of MAT in prisons and jails results in poor outcomes for individuals and poses a public health threat to communities. Furthermore, it disproportionately harms poor communities and communities of color. Health care providers in prisons and jails have an ethical obligation to offer MAT to individuals with opioid use disorder to mitigate risk of infectious diseases, opioid overdose and health disparities associated with incarceration.

Prisoners as Patients: The Opioid Epidemic, Medication-Assisted Treatment, and the Eighth Amendment

This article argues that correctional institutions violate the Eighth Amendment when they refuse to establish MAT programs and prevent doctors from exercising medical judgment to properly treat incarcerated people with OUD.
