Superiority and cost-effectiveness of monthly extended-release buprenorphine versus daily standard of care medication: a pragmatic, parallel-group, open-label, multicentre, randomised, controlled, phase 3 trial. EClinicalMedicine 2023; 66:102311. [PMID: 38045803 PMCID: PMC10692661 DOI: 10.1016/j.eclinm.2023.102311] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 10/26/2023] [Accepted: 10/26/2023] [Indexed: 12/05/2023] Open
Abstract
Background Daily methadone maintenance or buprenorphine treatment is the standard-of-care (SoC) medication for opioid use disorder (OUD). Subcutaneously injected, extended-release buprenorphine (BUP-XR) may be more effective-but there has been no superiority evaluation. Methods This pragmatic, parallel-group, open-label, multi-centre, effectiveness superiority randomised, controlled, phase 3 trial was conducted at five National Health Service community-based treatment clinics in England and Scotland. Participants (adults aged ≥ 18 years; all meeting DSM-5 diagnostic criteria for moderate or severe OUD at admission to their current maintenance treatment episode) were randomly assigned (1:1) to receive continued daily SoC (liquid methadone (usual dose range: 60-120 mg) or sublingual/transmucosal buprenorphine (usual dose range: 8-24 mg) for 24 weeks; or monthly BUP-XR (Sublocade;® two injections of 300 mg, then four maintenance injections of 100 mg or 300 mg, with maintenance dose selected by response and preference) for 24 weeks. In the intent-to-treat population (senior statistician blinded to blinded to treatment group allocation), and with a seven-day grace period after randomisation, the primary endpoint was the count of days abstinent from non-medical opioids between days 8-168 (i.e., weeks 2-24; range: 0-161 days). Safety was reported for the intention-to- treat population. Adopting a broad societal perspective inclusive of criminal justice, NHS and personal social service costs, a trial-based cost-utility analysis estimated the Incremental Cost-effectiveness Ratio (ICER) per quality-adjusted life year (QALY) of BUP-XR versus SoC at the National Institute for Health and Care Excellence threshold. The study was registered EudraCT (2018-004460-63) and ClinicalTrials.gov (NCT05164549), and is completed. Findings Between Aug 9, 2019 and Nov 2, 2021, 314 participants were randomly allocated to receive SoC (n = 156) or BUP-XR (n = 158). Participants were abstinent from opioids for an adjusted mean of 104.37 days (standard error [SE] 9.89; range: 0-161 days) in the SoC group and an adjusted mean of 123.43 days (SE 4.76; range: 24-161 days) in the BUP-XR group (adjusted incident rate ratio [IRR] 1.18, 95% confidence interval [CI] 1.05-1.33; p-value 0.004). The incidence of any adverse event was higher in the BUP-XR group than the SoC group (128 [81.0%] of 158 participants versus 67 [42.9%] of 156 participants, respectively-most commonly rapidly-resolving (mild-moderate range) pain from drug administration in the BUP-XR group (121 [26.9%] of 450 adverse events). There were 11 serious adverse events (7.0%) in the 158 participants in the BUP-XR group, and 18 serious adverse events (11.5%) in the 156 participants in the SoC group-none judged to be related to study treatment. The BUP-XR treatment group had a mean incremental cost of £1033 (95% central range [CR] -1189 to 3225) and was associated with a mean incremental QALY of 0.02 (95% CR 0.00-0.05), and an ICER of £47,540 (0.37 probability of being cost-effective at the £30,000/QALY gained willingness-to-pay threshold). However, BUP-XR dominated the SoC among participants who were rated more severe at study baseline, and among participants in maintenance treatment for more that 28 days at study enrolment. Interpretation Evaluated against the daily oral SoC, monthly BUP-XR is clinically superior, delivering greater abstinence from opioids, and with a comparable safety profile. BUP-XR was not cost-effective in a base case cost-utility analysis using the societal perspective, but it was more effective and less costly (dominant) among participants with more severe OUD, or those whose current treatment episode was longer than 28 days. Further trials are needed to evaluate if BUP-XR is associated with better clinical and health economic outcomes over the longer term. Funding Indivior.

[PMID: 37058181 PMCID: PMC10103423 DOI: 10.1186/s40352-023-00223-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Accepted: 04/05/2023] [Indexed: 06/19/2023]
Abstract
BACKGROUND Elevated mortality rates are found among people who have experienced incarceration, even long after release from prison. The mechanisms related to this excess mortality are complex products of both individual and situational factors. The aim of this study was to describe all-cause and cause-specific mortality among people with a history of imprisonment, and to examine both individual and situational factors associated with mortality. METHODS In this prospective cohort study we used baseline survey data from the Norwegian Offender Mental Health and Addiction (NorMA) study (N = 733) linked with data from the Norwegian Cause of Death Registry during eight years of follow-up (2013-2021). RESULTS At end of follow-up, 56 persons (8%) of the cohort were deceased; 55% (n = 31) due to external causes such as overdoses or suicides, and 29% (n = 16) to internal causes such as cancer or lung disease. Having a score > 24 on the Drug Use Disorders Identification Test (DUDIT), indicating likely drug dependence was highly associated with external causes of death (OR 3.31, 95% CI 1.34-8.16), while having a job before baseline imprisonment had a protective effect on all-cause mortality (OR 0.51, ,95% CI 0.28-0.95). CONCLUSIONS High DUDIT score at baseline were highly associated with external causes of death, even years after the DUDIT screening was done. Screening incarcerated people using validated clinical tools, such as the DUDIT, together with initiation of appropriate treatment, may contribute to reduced mortality in this marginalized population.

Abstract
This study aimed to investigate the long-term patterns and predictors of heroin use, dependence, and psychiatric health over 18-20 years among a cohort of Australians with heroin dependence, using a prospective longitudinal cohort study conducted in Sydney, Australia. The original cohort consisted of 615 participants, who were followed up at 3 months and 1, 2, 3, 11, and 18-20 years post-baseline; 401 (65.2%) were re-interviewed at 18-20 years. The Australian Treatment Outcome Study structured interview with established psychometric properties was administered to participants at each follow-up, addressing demographics, treatment and drug use history, overdose, crime, and physical and mental health. Overall, 96.7% completed at least one follow-up interview. At 18-20 years, 109 participants (17.7%) were deceased. Past-month heroin use decreased significantly over the study period (from 98.7 to 24.4%), with one in four using heroin at 18-20 years. Just under half were receiving treatment. Reductions in heroin use were accompanied by reductions in heroin dependence, other substance use, needle sharing, injection-related health, overdose, crime, and improvements in general physical and mental health. Major depression and borderline personality disorder (BPD) were consistently associated with poorer outcome. At 18-20 years, there is strong evidence that clinically significant levels of improvement can be maintained over the long term. The mortality rate over 18-20 years was devastating, with over one in six participants deceased. More sustained and targeted efforts are needed in relation to major depression and BPD to ensure evidence-based treatments are delivered to people with heroin dependence.

Abstract
Aims Consistent with the opponent process theory individuals with chronic opioid use should predominantly endorse the avoidance of aversive negative emotional and/or physiological states as the motivation for continued opioid use (source of reinforcement: reductions in negative states). The primary aim of this study was to explore whether this view is supported by the subjective effects of heroin reported by individuals with opioid use disorder (OUD). Methods Responses during in-person interviews of participants to the question "What do you like about heroin? " were categorized as positive, negative, or mixed (positive and negative) reinforcement. In addition, we examined differences between these "reinforcement groups" in sociodemographic and clinical variables. Results Participants (N = 307) with OUD were predominantly male (78.1%), with chronic heroin use (M = 15.8 years, SD = 11.5), and 46.1% currently used heroin and were not enrolled in treatment. Agreement between two raters concerning the categorization of participant-reported effects of heroin into reinforcement categories was high, κ= 0.924, p < .0005. Approximately half (49.8%) of participant-reported effects of heroin were categorized as attributable to positive reinforcement. About one-fourth (22.8%) were categorized as negative reinforcement and 9.0% as "mixed ". There were no statistically significant differences between the three reinforcement groups in any of the socio-demographic variables, duration of heroin use, or treatment status/interest. Conclusions The results of this study indicate marked heterogeneity of heroin effects experienced by individuals with OUD and their source of reinforcement, respectively. Better integration of how individuals construe their drug use is important to understand the psychological-and neurobiological-processes in the development and maintenance of OUD.

Abstract
Background: Unemployment rates for individuals in treatment for substance use disorder (SUD) are high, with Norwegian estimates in the range of 81%–89%. Although Individual Placement and Support (IPS) represents a promising method to improved vocational outcome, cross-disciplinary investigations are needed to document implementation benefits and address reimbursements needs. The aim of this study was to model the potential socioeconomic value of employment support integrated in SUD treatment. Methods: Based on scientific publications, an ongoing randomised controlled trial (RCT) on employment support integrated in SUD treatment, and publicly available economy data, we made qualified assumptions about costs and socioeconomic gain for the different interventions targeting employment for patients with SUD: (1) treatment as usual (TAU); (2) TAU and a self-help guide and a workshop; and (3) TAU and IPS. For each intervention, we simulated three different outcome scenarios based on 100 patients. Results: Assuming a 40% employment rate and full-time employment (100%) for 10 years following IPS, we found a 10-year socioeconomic effect of €18,732,146. The corresponding effect for the more conservative TAU + IPS simulation assuming 40% part-time positions (25%) for five years, was €2,519,906. Compared to the two alternative interventions, IPS was cost-effective and more beneficial after six months to two years. Discussion: This concept evaluation study suggests that integrating employment support in the health services is socioeconomically beneficial. Our finding is relevant for decision makers within politics and health. Once employment rates from our ongoing RCT is available, real-life data will be applied to adjust model assumptions and socioeconomic value assumptions.

Abstract
BACKGROUND Sublingual tablet buprenorphine (BUP-SL) and oral liquid methadone (MET) are the daily, standard-of-care (SOC) opioid agonist treatment medications for opioid use disorder (OUD). A sizable proportion of the OUD treatment population is not exposed to sufficient treatment to attain the desired clinical benefit. Two promising therapeutic technologies address this deficit: long-acting injectable buprenorphine and personalised psychosocial interventions (PSI). This study will determine (A) the effectiveness and cost-effectiveness - monthly injectable, extended-release (BUP-XR) in a head-to-head comparison with BUP-SL and MET, and (B) the effectiveness of BUP-XR with adjunctive PSI versus BUP-SL and MET with PSI. Safety, retention, craving, substance use, quality-adjusted life years, social functioning, and subjective recovery from OUD will be also evaluated. METHODS This is a pragmatic, multi-centre, open-label, parallel-group, superiority RCT, with a qualitative (mixed-methods) evaluation. The study population is adults. The setting is five National Health Service community treatment centres in England and Scotland. At each centre, participants will be randomly allocated (1:1) to BUP-XR or SOC. At the London study co-ordinating centre, there will also be allocation of participants to BUP-XR with PSI or SOC with PSI. With 24 weeks of study treatment, the primary outcome is days of abstinence from non-medical opioids during study weeks 2-24 combined with up to 12 urine drug screen tests for opioids. For 90% power (alpha, 5%; 15% inflation for attrition), 304 participants are needed for the BUP-XR versus SOC comparison. With the same planning parameters, 300 participants are needed for the BUP-XR and PSI versus SOC and PSI comparison. Statistical and health economic analysis plans will be published before data-lock on the Open Science Framework. Findings will be reported in accordance with the Consolidated Standards of Reporting Trials and Consolidated Health Economic Evaluation Reporting Standards. DISCUSSION This pragmatic randomised controlled trial is the first evaluation of injectable BUP-XR versus the SOC medications BUP-SL and MET, with personalised PSI. If there is evidence for the superiority of BUP-XR over SOC medication, study findings will have substantial implications for OUD clinical practice and treatment policy in the UK and elsewhere.

Abstract
BACKGROUND Conventional healthcare models struggle to engage those at risk of hepatitis C virus (HCV) infection. This international study evaluated point-of-care (PoC) HCV RNA diagnostic outreach and direct-acting antiviral (DAA) treatment for individuals receiving opioid agonist therapy (OAT) in community pharmacies. AIMS We assessed the effectiveness of a roving nurse-led pathway offering PoC HCV RNA testing to OAT clients in community pharmacies relative to conventional care. METHODS Pharmacies in Scotland, Wales, and Australia were randomised to provide PoC HCV RNA testing or conventional referral. Pharmacists directed OAT clients to on-site nurses (intervention) or local clinics (control). Infected participants were treated with DAAs, alongside OAT. Primary outcome was the number of participants with sustained virologic response at 12 weeks (SVR) and analysed using mixed effects logistic regression in the intention-to-treat (ITT) population. RESULTS Forty pharmacies were randomised. The ITT population contained 1410 OAT clients. In the conventional arm (n = 648), 62 (10%) agreed to testing, 17 (27%) were tested, 6 (35%) were positive and 5 (83%) initiated treatment. In the intervention arm (n = 762), 148 (19%) agreed to testing, 144 (97%) were tested, 23 (16%) were positive and 22 (96%) initiated treatment. SVR was obtained by 2 (40%; conventional) and 18 (82%; intervention). Intervention arm participants had higher odds of testing, OR 16.95 (7.07-40.64, p < 0.001); treatment, OR 4.29 (1.43-12.92, p = 0.010); and SVR, OR 8.64 (1.82-40.91, p = 0.007). CONCLUSIONS Nurse-led PoC diagnosis in pharmacies made HCV care more accessible for OAT clients relative to conventional care. However, strategies to improve testing uptake are required.

Abstract
BACKGROUND Epidemiological data from Mexico have documented an increase in heroin use in the last decade. However, there is no comprehensive care strategy for heroin users, especially those who have been accused of a crime. The objective of this study was to describe the heroin and methadone use of intravenous heroin users of both sexes who have been in jail, to offer evidence for the formulation of health policy. METHODS This study used an ethnographic approach, with open-ended interviews carried out from 2014 to the present. Heroin users of both sexes attending a private methadone clinic in Mexico City were invited to participate. The sample was non-probabilistic. All interviews were audiotaped and transcribed, and narratives were analyzed using thematic analysis. RESULTS Participants in this study were 33 users of heroin, two of them women, who had been in prison. They ranged in age from 33 to 62 years, had used heroin for a period of 13-30 years, and were from three states: Michoacan, Oaxaca, and Mexico City. Three principal categories of analysis were structured: 1. Pilgrimage for help (dynamics of the drama of suffering, pain, and time through health care spaces); 2) methadone use as self-care; and 3) accessibility to methadone treatment. The impossibility of access to methadone treatment is a condition which motivates users in their journey. The dynamics of methadone use are interpreted as a form of self-care and care to avoid substance use. Reducing the psychological, physical, and harmful effects of the substance allows them to perform daily activities. The inability to access treatment leads to a significant effect on users who experience structural violence. CONCLUSION Compassionate methadone treatment and holistic attention should be considered as a way to meet patients' needs and mitigate their suffering, based on public health policy that allows for human rights-based care.

Abstract
BACKGROUND Employment is associated with better outcomes of substance use treatment and protects against relapse after treatment completion. Unemployment rates are high for people with substance use disorders (SUD) who undergo treatment, with Norwegian estimates ranging from 81 to 91%. Evidence-based vocational models are lacking for patients in SUD treatment but exist for patients with psychosis in terms of Individual Placement and Support (IPS). The aim of the IPS for substance use disorders (IPS-SUD) trial is to investigate the effect of IPS in a SUD population. METHODS/DESIGN The IPS-SUD trial is a randomized controlled trial (RCT) comparing IPS to an enhanced control intervention. The study is a seven-site, two-arm, pragmatic, parallel-group, superiority RCT. Participants are randomly assigned (1:1) to receive either IPS plus treatment as usual (TAU) or to receive a self-help guide book and 12-h workshop plus 1-h individual vocational guidance plus TAU. Aiming to recruit 200 participants, we will be able to detect a 20% difference in the main outcome of employment with 90% power. We will make assessments at inclusion and at 6- and 12-month follow-ups and obtain outcome data on employment from national mandatory registries. The primary outcome will be at least 1 day of competitive employment during the 18-month follow-up period. Secondary employment outcomes will capture the pattern and extent of employment in terms of total time worked (days/hours), time to first employment, number of different jobs, duration of the longest employment, and sustained employment. Secondary non-employment outcomes will be substance use, mental distress, and quality of life measured by validated instruments at 6, 12, and 18 months follow-up assessments. To be eligible, participants must be between 18 and 65 years, currently unemployed and in treatment for SUD. DISCUSSION The IPS-SUD trial will provide evidence for the use of IPS in a SUD population. Findings from the study will have implications for service delivery. TRIAL REGISTRATION ClinicalTrials.gov NCT04289415 . Registered on February 28, 2020.

Longitudinal K-means approaches to clustering and analyzing EHR opioid use trajectories for clinical subtypes. J Biomed Inform 2021; 122:103889. [PMID: 34411708 PMCID: PMC9035269 DOI: 10.1016/j.jbi.2021.103889] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2021] [Revised: 07/26/2021] [Accepted: 08/13/2021] [Indexed: 10/20/2022]
Abstract
Identification of patient subtypes from retrospective Electronic Health Record (EHR) data is fraught with inherent modeling issues, such as missing data and variable length time intervals, and the results obtained are highly dependent on data pre-processing strategies. As we move towards personalized medicine, assessing accurate patient subtypes will be a key factor in creating patient specific treatment plans. Partitioning longitudinal trajectories from irregularly spaced and variable length time intervals is a well-established, but open problem. In this work, we present and compare k-means approaches for subtyping opioid use trajectories from EHR data. We then interpret the resulting subtypes using decision trees, examining how each subtype is influenced by opioid medication features and patient diagnoses, procedures, and demographics. Finally, we discuss how the subtypes can be incorporated in static machine learning models as features in predicting opioid overdose and adverse events. The proposed methods are general, and can be extended to other EHR prescription dosage trajectories.

Prospective Study on Factors Associated with Referral of Patients with Opioid Maintenance Therapy from Specialized Addictive Disorders Centers to Primary Care. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18115749. [PMID: 34071908 PMCID: PMC8198158 DOI: 10.3390/ijerph18115749] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Revised: 04/29/2021] [Accepted: 05/06/2021] [Indexed: 01/02/2023]
Abstract
Background: One of the most important issues for opiate maintenance therapy efficacy is the involvement of primary care physicians (PCPs) in opiate use disorder treatment, especially after referral from specialized units. This study aimed to analyze the progress of subjects in a specialized center and after referral to PCPs. Methods: This study was an observational prospective study. Recruitment took place in a specialized addictive disorder center in western France. All patients were evaluated (sociodemographical data, severity of substance use disorders through the TMSP scale, the quality of life through the TEAQV scale) by physicians during the 5-year-follow up of the study. Analysis focused on four main times during follow-up: entry/last visit into specialized care and into primary care. Results: 113 patients were included in this study; 93% were receiving methadone and 7% buprenorphine. Ninety (90) were referred to primary care. In primary care follow-up, the probability of the lowest severity score for substance use disorders remained stable over time. Conclusions: In daily practice, a center specialized in addictive disorders referred OMT management to PCPs for a majority of patients, and benefits regarding substance use disorders severity and quality of life remained stable after referral. Our results need to be confirmed.

Abstract
BACKGROUND AND AIM Extended-release naltrexone (XR-NTX) is an underused treatment option for opioid dependence, today only available in a few countries in the world. Although effective, safe and feasible in short-term treatment, long-term data are scarce and there is no recommendation for required treatment length. The aims of the study were to determine the perceived need of long-term XR-NTX treatment and to examine long-term treatment outcomes. DESIGN In this prospective cohort study, following a parent 1-year study of XR-NTX, participants received treatment with XR-NTX at their own discretion for a maximum of 104 weeks. SETTING Five urban, outpatient addiction clinics in Norway. PARTICIPANTS Opioid-dependent adults 18-60 years old (n=50) already participating in the parent study. INTERVENTION XR-NTX administrated as intra-muscular injections (380 mg) every 4 weeks. MEASUREMENTS Time in the study, use of opioids and other illicit substances, opioid craving, and treatment satisfaction reported every 4 weeks. FINDINGS Among 58 participants who completed the 1-year parent study, 50 chose to continue the treatment with XR-NTX. Median prolonged treatment time was 44.0 weeks (95% CI: 25.5-62.5), ranging from 8 to 104 weeks. Most participants (35, 70%) reported no relapse to opioid use during treatment while a subgroup (15, 30%) reported relapses to opioids during the study. Scores for mean treatment satisfaction and recommending treatment to others were very high (>9) and mean opioid craving score was very low (<1) on a scale ranging from 0 to 10. CONCLUSIONS Extended-release naltrexone (XR-NTX) was well tolerated in long-term treatment of opioid dependent individuals in Norway already in XR-NTX treatment. On average, the participants chose to continue treatment for almost 1 year beyond the initial 9 to 12 months of treatment. Participants reported high treatment satisfaction and 70% showed no relapse to opioids during the treatment period.

Living a normal life? Follow-up study of women who had been in opioid maintenance treatment during pregnancy. J Subst Abuse Treat 2020; 113:108004. [PMID: 32359675 DOI: 10.1016/j.jsat.2020.108004] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2019] [Revised: 03/04/2020] [Accepted: 03/28/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND There are few longitudinal follow-up studies of patients in opioid maintenance treatment (OMT). For this reason we performed a follow-up study of a cohort of 67 women who had used OMT-medications during pregnancy an average of ten years earlier. The aim of our study was to explore how the women were doing over time regarding OMT medication adherence and use of other legal and illegal substances, as well as to evaluate the mortality for the women and custody situation for the children in the cohort. METHODS Participants were recruited from two cohorts in our previous pregnancy study covering women who gave birth from 2004 to 2009. Sixty-seven women agreed to be interviewed, which is 73% of the eligible women from our original study. We developed a questionnaire, which we used in the interview, that focused primarily on these women's current life situation (custody of child they had delivered, the use of medications in OMT and other legal and illegal substances, and several other health and social aspects of the participants' lives). RESULTS Two women had died prior to the follow-up. Eighty-one percent of the women had custody of the child they had delivered in our pregnancy study and half the women were single parents. Fifty-four percent of the women were employed. At follow-up, 42% of the women were in methadone maintenance treatment (MMT), 39% were in buprenorphine maintenance treatment (BMT), and 19% had left OMT. One-third of the women had changed their OMT medication during the follow-up period. The majority (77%) were satisfied with their current OMT medication. The women in MMT seemed to be more severe substance dependent than the rest of the participants. There was little use of legal and illegal substances at follow-up, especially among women with custody of their child. The frequency of substance use was low. Fourteen percent of the women were in the process of leaving OMT and another half of the women wanted to leave OMT, but had no plan for how and when. CONCLUSION This follow-up study describes a predominantly well rehabilitated cohort of women who had given birth while in OMT ten years earlier. The majority of the women had custody of their children and used very few legal and illegal drugs. Our findings may be explained partly from a life course perspective, with the women having experienced turning points when starting OMT or becoming mothers.

Trajectories of heroin use predict relapse risk among heroin-dependent patients: A 5-year follow-up study. J Clin Neurosci 2020; 76:134-139.

Abstract
OBJECTIVES The relationship between past drug use trajectory and long-term relapse risk after rehabilitation among heroin-dependent patients remain understudied. The primary objectives were to identify longitudinal heroin use patterns of heroin-dependent patients, to determine the associative factors with trajectories and to investigate the impact of trajectory groups on relapse after finishing compulsory rehabilitation programs. MATERIALS AND METHODS A total of 564 heroin-dependent patients were recruited from 4 compulsory rehabilitation facilities in Shanghai, China between 2007 and 2008. The baseline data was linked to participants' follow-up data on relapse from official records. Group-based trajectory model was used to identify distinctive drug use trajectory groups. The association between the identified group and heroin relapse risk was then analyzed to understand the role of past drug use trajectory on relapse. RESULTS Five trajectory groups were identified in this cohort: (1) Rapid Decrease (9.9%); (2) Persistent High (32.0%); (3) Slow Decrease (34.1%); (4) Gradual Increase (4.5%); (5) Persistent Low (19.5%). Gender, age, education, and impulsivity were found to be different between the five groups. During the 5 years after discharged from the compulsory program, 291 (59.0%) individuals relapsed. Multivariate logistic regression analysis showed that the persistent high group (OR: 2.77 [1.46-5.24]), slow decrease group (OR: 2.31 [1.32-4.06]) and gradual increase group (OR: 3.50 [1.18-10.39]) was positively associated with the heroin relapse risk when compared to the persistent low group. CONCLUSIONS Heroin use trajectories vary among heroin-dependent patients in China. The trajectories of heroin use before compulsory rehabilitation are associated with subsequent long-term relapse risk.

Abstract
OBJECTIVES To advance our understanding of medication treatments for opioid use disorders (OUDs), identification of distinct subgroups and factors associated with differential treatment response is critical. We examined trajectories of opioid use for patients with OUD who were randomized to (but not in all cases inducted onto) buprenorphine-naloxone (BUP-NX) or extended-release naltrexone (XR-NTX), and identified characteristics associated with each trajectory. METHODS Growth mixture models (GMMs) were run to identify distinct trajectories of days of opioid use among a subsample of 535 individuals with OUD who participated in a 24-week randomized controlled trial (RCT; 2014-2016) of BUP-NX (n = 281) or XR-NTX (n = 254). RESULTS Four distinct opioid use trajectory classes were identified for BUP-NX (near abstinent/no use (59%); low use (13.2%); low use, increasing over time (15%); and moderate use, increasing over time (12.8%)). Three distinct opioid use trajectory classes were found for XR-NTX (near abstinent/no use (59.1%); low use (14.6%); and moderate use, increasing over time (26.4%)). Across both BUP-NX and XR-NTX, the near abstinent/no use class had the highest number of medical management visits. Within BUP-NX, the low use class had a greater proportion of individuals with a previous successful treatment history compared with other classes. Within XR-NTX, the moderate use, increasing over time class had the highest proportion of Hispanic participants compared with other classes. CONCLUSIONS Findings highlight the significant heterogeneity of opioid use during a RCT of BUP-NX and XR-NTX and factors associated with opioid use patterns including medical management visits and history of treatment success.

Abstract
CONTEXT AND PURPOSE Measurement-based care (MBC) is an evidence-based health-care practice in which indicators of disease are tracked to inform clinical actions, provide feedback to patients and improve outcomes. The current opioid crisis in multiple countries provides a pressing rationale for adopting a basic MBC approach for opioid use disorder (OUD) using DSM-5 to increase treatment retention and effectiveness. PROPOSAL To stimulate debate, we propose a basic MBC approach using the 11 symptoms of OUD (DSM-5) to inform the delivery of medications for opioid use disorder (MOUD; including methadone, buprenorphine and naltrexone) and their evaluation in office-based primary care and specialist clinics. Key features of a basic MBC approach for OUD using DSM-5 are described, with an illustration of how clinical actions are guided and outcomes communicated. For core treatment tasks, we propose that craving and drug use response to MOUD should be assessed after 2 weeks, and OUD remission status should be evaluated at 3, 6 and 12 months (and exit from MOUD treatment) and beyond. Each of the 11 DSM-5 symptoms of OUD should be discussed with the patient to develop a case formulation and guide selection of adjunctive psychological interventions, supplemented with information on substance use, and optionally extended with information from other clinical instruments. A patient-reported outcome measure should be recorded and discussed at each remission assessment. CONCLUSIONS MBC can be used to tailor and adapt MOUD treatment to increase engagement, retention and effectiveness. MBC practice principles can help promote patient-centred care in OUD, personalized addiction therapeutics and facilitate communication of outcomes.

Efficacy and cost-effectiveness of an adjunctive personalised psychosocial intervention in treatment-resistant maintenance opioid agonist therapy: a pragmatic, open-label, randomised controlled trial. Lancet Psychiatry 2019; 6:391-402.

Abstract
BACKGROUND Opioid use disorder is a chronic, debilitating, and costly disorder that has increased in prevalence in many countries, with an associated sharp rise in mortality. Maintenance opioid agonist therapy is the first-line treatment, but many patients do not stop using illicit or non-prescribed drugs concomitantly. We aimed to test the efficacy and cost-effectiveness of a personalised psychosocial intervention implemented with a toolkit of behaviour-change techniques as an adjunct to opioid agonist therapy. METHODS We did a pragmatic, open-label, randomised controlled trial at a specialist UK National Health Service community addictions clinic in London, UK. Eligible patients were aged 18 years or older, met criteria for opioid or cocaine dependence, or both, in the past 12 months, and voluntarily sought continued oral maintenance opioid agonist therapy, which they had been prescribed for at least 6 weeks. All participants were treatment resistant (ie, had used illicit or non-prescribed opioids or cocaine on one or more days in the past 28 days at study screening, which was verified by positive urine drug screen). Participants were allocated (1:1) by a web-accessed randomisation sequence (stratified by opioid agonist medication, current cocaine use, and current rug use) to receive a personalised psychosocial intervention (comprising a flexible toolkit of psychological-change methods, including contingency management to reinforce abstinence, recovery activities, and clinic attendance) in addition to treatment as usual, or treatment as usual only (control group). The primary outcome was treatment response at 18 weeks, which was defined as abstinence from illicit and non-prescribed opioids and cocaine in the past 28 days, as measured with treatment outcomes profiles and urine drug screening. Taking a societal cost perspective, we did an evaluation of cost-effectiveness with a wide range of willingness-to-pay values for a unit improvement in the probability of treatment response. We also calculated quality-adjusted life-years (QALYs). Efficacy was analysed in a modified-intention-to-treat population, including all participants who were randomly allocated but excluding those who had previously completed the intervention. This trial is registered with ISRCTN, number ISRCTN69313751. The trial is completed. FINDINGS Between June 7, 2013, and Dec 21, 2015, we randomly allocated 136 participants to the psychosocial intervention group and 137 to the control group. The trial database was locked on April 19, 2017. Three patients (one in the psychosocial intervention group and two in the control group) who were re-randomised in error were excluded from the analysis. 22 (16%) of 135 patients in the psychosocial intervention group had a treatment response, compared with nine (7%) of 135 in the control group (adjusted log odds 1·20 [95% CI 0·01-2·37]; p=0·048). The psychosocial intervention had a higher probability of being cost-effective than treatment as usual. There was a probability range of 47-87% for willingness-to-pay thresholds of £0-1000 for a unit improvement in the probability of treatment response. QALYs were higher in the psychosocial intervention group than in the control group (mean difference 0·048 [95% CI 0·016-0·080]; p=0·004) in adjusted analyses, with 60% and 67% probabilities of cost-effectiveness at the UK National Institute for Health and Care Excellence's willingness-to-pay thresholds of £20 000 and £30 000 per QALY, respectively. The number of adverse events was similar between groups, and no severe adverse events in either group were judged to be treatment related. One participant in the control group was hospitalised with drug-injection-related sepsis and died. INTERPRETATION In maintenance opioid agonist therapy, an adjunctive personalised psychosocial intervention in addition to standard therapy was efficacious and cost-effective compared with standard therapy alone at helping treatment-resistant patients abstain from using illicit and non-prescribed opioids and cocaine.

Abstract
BACKGROUND English national prospective, observational cohort study of patients continuously enrolled for five years in opioid substitution treatment (OST) with oral methadone and sublingual buprenorphine. This is a secondary outcome analysis of change in use of alcohol and other drug use (AOD) following identification of heroin use trajectories during OST. METHODS All adults admitted to community OST in 2008/09 and enrolled to 2013/14 (n = 7717). Data from 11 sequential, six-monthly clinical reviews were used to identify heroin and AOD use trajectories by multi-level Latent Class Growth Analysis. OST outcome in the sixth and seventh year was 'successful completion and no re-presentation' (SCNR) to structured treatment and was assessed using multi-level logistic regression. RESULTS With 'rapid decreasing' heroin use trajectory as referent, 'continued high-level' heroin use predicted 'continued high-level' crack cocaine use (relative risk ratio [RRR] 58.7; 95% confidence interval [CI] 34.2-100.5),'continued high-level' alcohol use (RRR 1.2; 95% CI 1.0-1.5), 'increasing' unspecified drug use (RRR 1.7; 95% CI 1.4-2.1) and less 'high and increasing' cannabis use (RRR 0.5; 95% CI 0.4-0.6). 'Increasing' crack use was negatively associated with SCNR outcome for the 'decreasing then increasing' and 'gradual decreasing' heroin use groups (adjusted odds ratio [AOR] 0.5; 95% CI 0.3-0.9 and AOR 0.2; 95% CI 0.1-0.7, respectively). CONCLUSIONS Continued high-level heroin use non-response during long-term OST is associated with high-level crack cocaine and alcohol use, increasing unspecified drug use, but less high and increasing cannabis use. Increasing use of crack cocaine is negatively associated with the likelihood that long-term OST is completed successfully.
