Perspectives on Diversion of Medications From Safer Opioid Supply Programs

Importance

Safer supply programs were implemented in Canada to provide pharmaceutical-grade alternatives to the toxic unregulated drug supply. While research shows clinical benefits and reduced overdose mortality among safer supply patients, medication diversion remains a concern.

Objective

To examine provider (prescribing clinicians and allied health professionals) and patient perspectives on diversion of opioids prescribed in safer supply programs.

Design, Setting, and Participants

In 2021, qualitative interviews and sociodemographic questionnaires were conducted with patients and providers across 4 safer supply programs in Ontario, Canada. Interviews with 21 providers (physicians, nurse practitioners, and allied health professionals) and 52 patients examined experiences implementing safer supply or receiving care. Initial data analysis was conducted from December 2021 to March 2022, and the subanalysis focused on diversion was conducted from December 2023 to March 2024.

Exposures

Participation in safer supply program as a patient or provider.

Main Outcomes and Measures

Data about diversion were coded, extracted, and thematically analyzed.

Results

Of 52 patient participants, 29 (55.8%) were men and 23 (44.2%) were women; 1 was Black (1.9%), 9 (17.3%) were Indigenous, 1 was Latino (1.9%), and 41 (78.8%) were White; and the mean (SD) age was 46.5 (9.6) years. Of 21 provider participants, 6 (28.6%) were men, 13 (61.9%) were women, and 2 (9.5%) were nonbinary; and the mean (SD) age was 37.6 (7.6) years. Participants characterized diversion as a spectrum ranging from no diversion, to occasional medication sharing and loss, to selling all prescribed doses of safer supply (considered rare and easy to detect). Most patients reported they consumed all or most of their prescribed medications and rarely shared or sold their doses. However, providers and patient participants shared that people might share, trade, and/or sell some of their medications with other opioid-using people for multiple reasons. Most prominent reasons for diversion were (1) compassionate sharing with intimate partners and friends to manage withdrawal and overdose risk; (2) selling or trading medications to address their own unmet substance use needs (eg, high opioid tolerance); and (3) medication loss due to poverty, homelessness, and associated vulnerabilities to theft and coercion. Programs used nonpunitive urine drug screening practices and patient self-report to monitor medication use. When diversion was identified, providers described using nonjudgmental conversations to understand patients' needs and develop mitigation strategies that addressed underlying reasons for diversion, including changing doses and medications prescribed to better match patients' needs, enrolling eligible intimate partners, and developing safety plans to mitigate vulnerabilities to theft and coercion.

Conclusions and Relevance

Diversion encompasses a wide spectrum of practices (selling, sharing, and loss of medications), and occurs for complex reasons that surveillance and punitive measures are unlikely to mitigate. Diversion may be best addressed by expanding medication options to better match patients' diverse substance use needs and high tolerance, alongside wraparound social supports.

Time for Australia to increase take away doses in opioid agonist treatment

Opioid Agonist Treatment is the cornerstone of minimising harms related to opioid use, however its uptake is limited by a tightly regulated and stigmatising treatment environment. The COVID-19 pandemic necessitated relaxation of some treatment restrictions, with global evidence pointing to more patient-centred care in this time. In light of local evidence to support the safety of increased access to takeaway doses and a precedent set by the Substance Abuse and Mental Health Administration, we recommend adoption of the Australian Interim Medication Assisted Treatment of Opioid Dependence guidance in Australia.

Supervised on-site dosing in injectable opioid agonist treatment-considering the patient perspective. Findings from a cross-sectional interview study in two German cities

BACKGROUND

Injectable opioid agonist treatment (iOAT) is an effective option to support people living with opioid use disorder (OUD) who have not sufficiently benefitted from oral OAT. However, iOAT has been criticised based on theoretical and practical grounds for its dosing policies: Current regulations demand supervised, on-site application and require patients to frequently visit their treatment facility. The current study aims to investigate how patients experience on-site application and derive strategies to enhance the acceptability and effectiveness of iOAT-delivery.

METHODS

This article is based on semi-structured interviews with 27 individuals currently or previously in iOAT in two German outpatient iOAT-clinics. We undertook an inductive qualitative content analysis, which included blinded, independent coding and the analysis of individual cases.

RESULTS

Comments regarding on-site application and daily visits to the clinic were grouped into positive and negative aspects, iOAT as the best alternative option, facilitators of daily visits, and suggestions for improvement. Positive aspects took the factors stability and social support in regard. Negative aspects ranged from general inconveniences to major impediments to individuals' daily lives and towards achieving psychosocial goals. Participants reported rigorous adherence to iOAT's treatment regime, often due to a perceived lack of alternative options. Meeting iOAT's demands was eased by the patients' coping-strategies and through facilitating measures implemented by iOAT-clinics. Despite acknowledgement of the potential detriments from easing regulations, take-home arrangements were frequently suggested by participants to improve iOAT.

CONCLUSIONS

Being required to attend the clinic for supervised iOAT-application is not experienced uniformly. While clinics can support their patients to cope with strict regulations, alternative approaches to iOAT-application should be considered to accommodate patients' individual needs. Examples from other treatment modalities (e.g., remote supervision and delivery services) might aid to reconcile individualisation while providing adequate safety measures and improve iOAT in the long term.

Long-Acting Buprenorphine Formulations as a New Strategy for the Treatment of Opioid Use Disorder

Long-acting buprenorphine formulations have been recently marketed for the Opioid Agonist Treatment (OAT) of opioid use disorder (OUD) associated with medical, social, and psychological support. Their duration of action ranges from one week up to 6 months. The non-medical use of opioids is increasing with a parallel rise in lethal overdoses. Methadone and buprenorphine are the standard treatment for opioid dependence. Methadone Maintenance Treatment (MMT) is widely recognized as one of the most effective ways of reducing the risks of overdose, crime, and transmission of HIV (Human Immunodeficiency Virus) in people who use opioids; however, its effectiveness has been hindered by low rates of uptake and retention in treatment. Furthermore, both methadone and buprenorphine are widely diverted and misused. Thus, a crucial aspect of treating OUD is facilitating patients' access to treatment while minimizing substance-related harm and improving quality of life. The newly developed long-acting buprenorphine formulations represent a significant change in the paradigm of OUD treatment, allowing an approach individualized to patients' needs. Strengths of this individualized approach are improved adherence (lack of peaks and troughs in blood concentrations) and a reduced stigma since the patient doesn't need to attend their clinic daily or nearly daily, thus facilitating social and occupational integrations as the quality of life. However, less frequent attendance at the clinic should not affect the patient-physician relationship. Therefore, teleconsulting or digital therapeutic services should be developed in parallel. In addition, diversion and intravenous misuse of buprenorphine are unlikely due to the characteristics of these formulations. These features make this approach of interest for treating OUD in particular settings, such as subjects staying or when released from prison or those receiving long-term residential treatment for OUD in the therapeutic communities. The long-lasting formulations of buprenorphine can positively impact the OUD treatment and suggest future medical and logistic developments to maximize their personalized management and impact.

Clients' experiences on North America's first take-home injectable opioid agonist treatment (iOAT) program: a qualitative study

BACKGROUND

To support public health measures during the COVID-19 pandemic, oral opioid agonist treatment (OAT) take-home doses were expanded in Western countries with positive results. Injectable OAT (iOAT) take-home doses were previously not an eligible option, and were made available for the first time in several sites to align with public health measures. Building upon these temporary risk-mitigating guidelines, a clinic in Vancouver, BC continued to offer two of a possible three daily doses of take-home injectable medications to eligible clients. The present study explores the processes through which take-home iOAT doses impacted clients' quality of life and continuity of care in real-life settings.

METHODS

Three rounds of semi-structured qualitative interviews were conducted over a period of seventeen months beginning in July 2021 with eleven participants receiving iOAT take-home doses at a community clinic in Vancouver, British Columbia. Interviews followed a topic guide that evolved iteratively in response to emerging lines of inquiry. Interviews were recorded, transcribed, and then coded using NVivo 1.6 using an interpretive description approach.

RESULTS

Participants reported that take-home doses granted them the freedom away from the clinic to have daily routines, form plans, and enjoy unstructured time. Participants appreciated the greater privacy, accessibility, and ability to engage in paid work. Furthermore, participants enjoyed greater autonomy to manage their medication and level of engagement with the clinic. These factors contributed to greater quality of life and continuity of care. Participants shared that their dose was too essential to divert and that they felt safe transporting and administering their medication off-site. In the future, all participants would like more accessible treatment such as access longer take-home prescriptions (e.g., one week), the ability to pick-up at different and convenient locations (e.g., community pharmacies), and a medication delivery service.

CONCLUSIONS

Reducing the number of daily onsite injections from two or three to only one revealed the diversity of rich and nuanced needs that added flexibility and accessibility in iOAT can meet. Actions such as licencing diverse opioid medications/formulations, medication pick-up at community pharmacies, and a community of practice that supports clinical decisions are necessary to increase take-home iOAT accessibility.

Misuse of Over the Counter and Prescription Only Medication by Adults Accessing Specialist Treatment Services in the UK: A Narrative Synthesis

Background

Concerns about the misuse of over the counter (OTC) and prescription only medication (POM) are due to their impact upon physical/mental wellbeing, drug interactions and drug-related deaths. Improving an understanding of the pattern of use by people accessing specialist substance misuse services (SMSs) should enable improvements to treatment provision.

Aim

To review the literature on the misuse of OTC/POM among adults accessing SMS, including the pattern of use, types of medication and associated characteristics.

Methods

This review is reported in line with PRISMA. The protocol has been registered on PROSPERO (CRD42020135216) and separately published. A search of Cochrane, OVID Medline, Pubmed, Scopus and Web of Science databases and grey literature was undertaken. Only English language publications outlining OTC/POM misuse by adults in receipt of psychological/pharmacological interventions for substance misuse were included. Two reviewers conducted the title, abstract and full-text reviews using predetermined selection criteria and a piloted data extraction form to ensure a consistent approach. A third reviewer resolved disagreements and the Mixed Methods Appraisal Tool assessed for bias. Ethical approval was not required.

Results

Thirteen studies with notable heterogeneity were included in the narrative synthesis after non-UK-based and ineligible publications were excluded, from the 143 potentially relevant papers. To reduce bias all studies were included in the analysis and GRADE-CERQual was applied. 'High confidence' was identified for all review findings, despite moderate methodological limitations. Antihistamine, benzodiazepine and opioid misuse was mentioned most frequently. Usage patterns and supply sources varied. Adverse consequences and polypharmacy are concerning. Withdrawal symptoms perpetuated misuse, often alongside illicit substance use, comorbid psychiatric/pain disorders and street drug shortages.

Conclusion

OTC/POM misuse is common amongst adults accessing SMS. A renewed approach to withdrawal management is required. The limited number of studies may impact on generalisability but allowed for a more detailed review. Restricting to UK studies improved relevance due to drug market variations and availability of medicines in different countries. Further UK-based research on OTC/POM misuse in SMS is needed to build upon the current paucity in the published literature.

Public health risks associated with methadone in Iran: A systematic review and meta-analysis

BACKGROUND

There has been a marked growth in methadone maintenance treatment (MMT) in Iran in the past two decades with positive health outcomes. We conducted a systematic review of studies on the prevalence of non-prescribed methadone use, methadone use disorder, and methadone-related poisoning and mortality in Iran.

METHODS

We searched International and Iranian databases up to May 2020 and contacted relevant experts. The pooled proportions were estimated through random-effects model. Methadone-related adverse outcomes were evaluated over time.

RESULTS

Sixty-five studies were included. The pooled estimates of non-prescribed methadone use in the last 12-month were 2.7% (95%CI: 0.9-5.4) and 0.1% (95%CI: 0.03-0.2) in the male and female general population, respectively. Among people who use drugs, 8.4% reported daily non-prescribed use in 2018. Four heterogeneous studies in drug treatment centers reported the existence of treatment-seeking for methadone use disorder. Methadone was responsible for 10.4% (95%CI: 4.5-18.3) of cases of acute poisoning in adults and 16.0% (95%CI: 9.3-24.1) in children. Methadone was reported as a cause of death in 53.5% of substance-related deaths referred to the Legal Medicine Organization while being the only cause in 35.8% of all cases.

CONCLUSION

Non-prescribed use of methadone in the general population is much less than opiates and some other available prescription opioids, like tramadol. However, notwithstanding the large and successful MMT program in Iran, increasing trends in methadone-related poisoning and deaths pose serious public health concerns. There is an urgent need to explore these fatal and non-fatal poisoning cases and implement policies to curb the harms associated with methadone use.

Phytochemical and Over-The-Counter Drug Interactions: Involvement of Phase I and II Drug-Metabolizing Enzymes and Phase III Transporters

Consumption of plant-derived natural products and over-the-counter (OTC) drugs is increasing on a global scale, and studies of phytochemical-OTC drug interactions are becoming more significant. The intake of dietary plants and herbs rich in phytochemicals may affect drug-metabolizing enzymes (DMEs) and transporters. These effects may lead to alterations in pharmacokinetics and pharmacodynamics of OTC drugs when concomitantly administered. Some phytochemical-drug interactions benefit patients through enhanced efficacy, but many interactions cause adverse effects. This review discusses possible mechanisms of phytochemical-OTC drug interactions mediated by phase I and II DMEs and phase III transporters. In addition, current information is summarized for interactions between phytochemicals derived from fruits, vegetables, and herbs and OTC drugs, and counseling is provided on appropriate and safe use of OTC drugs.

Executive Summary of the Focused Update of the ASAM National Practice Guideline for the Treatment of Opioid Use Disorder

: A Focused Update of the ASAM National Practice Guideline for the Treatment of Opioid Use Disorder is published in the current issue of the Journal of Addiction Medicine. The focused update included a search of Medline's PubMed database from January 1, 2014 to September 27, 2018, as well as a search of the grey literature (archives of the Clinical Guideline Clearinghouse, and key agency and society websites) for new practice guidelines and relevant systematic reviews addressing the use of medications and psychosocial treatments in the treatment of opioid use disorder, including within special populations. The search identified 11 practice guidelines and 35 systematic reviews that informed the subsequent RAND/UCLA Appropriateness Method (RAM) process employed to facilitate the focused update by a National Guideline Committee of addiction experts. New and updated recommendations were included if they were considered: (a) clinically meaningful and applicable to a broad range of clinicians treating addiction involving opioid use; and (b) urgently needed to ensure the Practice Guideline reflects the current state of the science for the existing recommendations, aligns with other relevant practice guidelines, and reflects newly approved medications and formulations.

Using contact-based education to destigmatize opioid use disorder among medical students

All first- and second-year (i.e., pre-clinical) medical students at a large, Midwestern medical school with three campuses were invited to participate in a two-arm, parallel educational study comparing the efficacy of two types of curricular interventions. Students at the main campus attended the modified contact-based education panel or the didactic lecture in person, while students at the two distance campuses attended the modified contact-based education or lecture remotely using the University's videoconferencing system. Impact: A total of 109 students participated in the study (average age 24.2 years (SD = 2.6), 64.2% female, 79.8% white, 56.0% second-year students, 67.9% attended on main campus, lecture = 52 participants, modified contact-based = 57 participants). Baseline responses were similar across groups. Following the session, participants in both interventions rated drug abuse (percent increase = 21.2%, p < .001) and prescription drug diversion (percent increase = 7.6%, p = .004) as more serious problems. Participants from both interventions expressed increased confidence in caring for patients with OUD (percent increase = 45.5%, p < .001) and increased interest in pursuing MAT training (percent increase = 21.5%, p = .04). Both curricular interventions were equally effective at reducing OUD stigma with a significant 8.2% decrease in total stigma scores and a large effect size (p < .001, η_p² = .34). Lastly, participants with lower post-assessment OUD stigma scores were more likely to indicate that they would pursue additional training to provide MAT (p = .02). Lessons learned: Exposure to opioid-specific education with a focus on MAT and recovery, regardless of education type, positively affected opioid-related postgraduate intentions and reduced OUD stigma. Notably, these findings suggest that there are multiple efficacious techniques to reduce OUD stigma during preclinical training.

Take home injectable opioids for opioid use disorder during and after the COVID-19 Pandemic is in urgent need: a case study

Background

In North America the opioid poisoning crisis currently faces the unprecedented challenges brought by the COVID-19 pandemic, further straining people and communities already facing structural and individual vulnerabilities. People with opioid use disorder (OUD) are facing unique challenges in response to COVID-19, such as not being able to adopt best practices (e.g., physical distancing) if they’re financially insecure or living in shelters (or homeless). They also have other medical conditions that make them more likely to be immunocompromised and at risk of developing COVID-19. In response to the COVID-19 public health emergency, national and provincial regulatory bodies introduced guidance and exemptions to mitigate the spread of the virus. Among them, clinical guidance for prescribers were issued to allow take home opioid medications for opioid agonist treatment (OAT). Take Home for injectable opioid agonist treatment (iOAT) is only considered within a restrictive regulatory structure, specific to the pandemic. Nevertheless, this risk mitigation guidance allowed carries, mostly daily dispensed, to a population that would not have access to it prior to the pandemic. In this case it is presented and discussed that if a carry was possible during the pandemic, then the carry could continue post COVID-19 to address a gap in our approach to individualize care for people with OUD receiving iOAT.

Case presentation

Here we present the first case of a patient in Canada with long-term OUD that received take home injectable diacetylmorphine to self-isolate in an approved site after being diagnosed with COVID-19 during a visit to the emergency room where he was diagnosed with cellulitis and admitted to receive antibiotics.

Conclusion

In the present case we demonstrated that it is feasible to provide iOAT outside the community clinic with no apparent negative consequences. Improving upon and making permanent these recently introduced risk mitigating guidance during COVID-19, have the potential not just to protect during the pandemic, but also to address long-overdue barriers to access evidence-based care in addiction treatment.

Medicine misuse: A systematic review and proposed hierarchical terminology

AIMS

Although medicine misuse is a public health issue, it has multiple meanings in the medical literature. This study aimed to characterize, classify and identify the most appropriate definitions of medicine misuse.

METHODS

A systematic review was performed in Medline, ISI Web of Science, SocINDEX, PsycInfo, PsycArticles and Psychological and Behavioral Sciences Collection, using keywords related to "misuse", "appropriateness" and "medicine" between 1 November 2008 and 25 August 2020. Additional searches were conducted in websites of regulatory agencies and public health institutions. Two authors independently selected studies providing both definitions and examples of misuse, while a third resolved disagreements. Definitions were used to propose a hierarchical classification based on initiator, intent, purpose and context of medicine misuse. The study is registered on PROSPERO: CRD42018115789.

RESULTS

Of 3404 identified records, 51 were included. A total of 71 definitions and 74 examples of misuse were retrieved. When the prescriber is initiator and according to intent, potential medicine misuse referred to "intentional or unintentional prescribing not in line with clinical evidence". Based on context, they could prescribe medicines not clinically justified, i.e. overprescribing, or prescribe indicated medicines incorrectly, i.e. misprescribing. Among other groups of definitions, those overlapping with drug abuse or medication use errors were considered out-of-scope.

CONCLUSION

This systematic review provides a comprehensive overview of the terms and definitions used to characterize medicine misuse and could serve as a basis for a terminology that makes clear distinctions between misuse, abuse and errors.

The lived experience of Australian opioid replacement therapy recipients in a community-based program in regional Victoria

INTRODUCTION AND AIMS

Treatment of opioid dependence through opioid replacement therapy is widely recognised as effective. Nonetheless, while there has been a community-based program in the state of Victoria for over two decades, consumer experiences have received little attention. This study aimed to describe the experiences of opioid replacement therapy consumers living in rural and regional areas of the state.

DESIGN AND METHODS

A qualitative design employed an interpretative phenomenological approach. Sixteen consumers were interviewed. Thematic analysis was conducted by the researchers to examine the phenomena of consumers' experiences and findings were verified by a stakeholder group.

RESULTS

Findings centred on themes of consumers' experience of becoming recipients; consumer perceptions of pharmacists and pharmacy settings and psychosocial impacts on consumers. A majority of participants believed opioid replacement therapy brought increased normality to their life, however systemic and psychosocial barriers impacted on well-being. The pharmacy setting itself as a public dosing space commonly provoked feelings of stigma and discrimination among consumers. Other barriers prominently reported were restrictions on number of takeaways, cost of dispensing and lack of access to medical practitioners and allied supports.

DISCUSSION AND CONCLUSIONS

There were psychosocial impacts on opioid replacement therapy consumers relating to financial and social burdens, stigma and discrimination. Access to medical care and a choice of pharmacy appeared to be restricted in rural regions. The findings suggest a need to address, in particular, the financial and dispensing point burdens experienced by consumers to facilitate program retention.

Adolescent and Parent Knowledge, Attitudes, and Perceptions of Harm of Household Controlled Medications

Introduction: Adolescents learn knowledge, attitudes, and behaviors from their parents, yet little is known about how these attributes are associated with management of household controlled prescription medications. We aimed to assess adolescent and parent: 1) knowledge and attitudes regarding household controlled medications, including previous healthcare counseling; 2) perceptions of harm of medication misuse and diversion; and 3) potential associations of these attributes with household management. Methods: This was a cross-sectional study with paired data using brief, online, confidential surveys of adolescents and parents via an adolescent medicine clinic associated with a large academic center. Eligible adolescents were aged 12-18 years old with at least one controlled prescription medication in the home. Data collection and analysis occured in 2017-2018. Results: Of the 243 adolescent-parent dyads, many adolescents and parents had: low knowledge (15%; 6%), risky attitudes (31%; 32%), received healthcare counseling on safe management of controlled medications (30%; 96%), and low perceived harm of adolescent diversion (39%; 49%). Parents practicing unsafe household management were 2.4 (95% CI = 1.3, 4.3) times as likely to have risky attitudes. Adolescents with families practicing unsafe medication management were 3.7 (95% CI = 1.1, 10.4) times as likely to have low perceptions of harm from diversion. Conclusions: Many adolescents and parents have low knowledge, risky attitudes, and low perceptions of harm of adolescent diversion, some of which are associated with unsafe household medication management. Providers should aim to utilize interventions to improve these attributes for adolescents and parents to enhance safe household medication management.

Long-term safety of a weekly and monthly subcutaneous buprenorphine depot (CAM2038) in the treatment of adult out-patients with opioid use disorder

AIMS

To assess the long-term safety of subcutaneous buprenorphine (CAM2038) weekly and monthly depots.

DESIGN

Phase 3, open-label, observational, multi-centre 48-week trial (ClinicalTrials.gov NCT02672111).

SETTING

Twenty-six out-patient sites (United States, United Kingdom, Hungary, Denmark, Sweden, Germany, Australia) between 14 December 2015 and 12 April 2017.

PARTICIPANTS

Two hundred and twenty-eight adults with opioid use disorder; 227 received CAM2038 (37 initiated onto CAM2038 and 190 converted from sublingual buprenorphine).

INTERVENTIONS

CAM2038 weekly (8, 16, 24 or 32 mg) or monthly (64, 96, 128 or 160 mg) with flexible dosing and individualized titration utilizing multiple CAM2038 weekly and monthly doses.

MEASUREMENTS

Safety variables, urine toxicology samples and self-reported illicit opioid use were collected at each visit. Participants were administered a patient satisfaction survey at months 6 and 12, completed by 162 of 227 (71.4%) participants.

FINDINGS

The study treatment period was completed by 167 of 227 (73.6%) participants. At least one treatment-emergent adverse event (TEAE) was reported by 143 of 227 (63.0%) participants, of whom 60 of 227 (26.4%) reported as being drug-related. Most of the TEAEs, reported by 128 of 227 (56.4%) of participants, were mild or moderate in intensity. Injection-site reactions were reported by 46 of 227 (20.3%) participants, with most [45 of 46 (97.8%)] reported as mild to moderate. Five participants (2.2%) discontinued the study drug due to a TEAE, two cases (0.9%) of which were injection-site-related. No serious adverse events were attributed to the study drug. Among those remaining in the study, the percentage of opioid-negative urine tests combined with self-reports was 63.0% (17 of 27) in new-to-treatment participants and 82.8% (111 of 134) for those converted from sublingual buprenorphine. Participants reported high levels of satisfaction with CAM2038.

CONCLUSIONS

Subcutaneous buprenorphine delivered weekly or monthly (CAM2038) was well tolerated, with a systemic safety profile consistent with the known profile of sublingual buprenorphine. CAM2038 weekly and monthly was associated with high retention rates and low levels of illicit opioid use throughout this study.

Comparative study between prison- and community-based treatment satisfaction for opioid use disorder in Lebanon

PURPOSE

Opioid substitution treatment (OST), such as Buprenorphine, has become a well-established evidence-based approach for the treatment of inmates with opioid use disorder (OUD) in most of the developed world. However, its application in Lebanon remains mainly as a community-based intervention. The purpose of this paper is to highlight the need of its implementation within the Lebanese correctional system.

DESIGN/METHODOLOGY/APPROACH

The work is a pilot cross-sectional study that compares two groups: 30 male adult prisoners with OUD convictions receiving symptomatic treatment and 30 male adult community patients with OUD receiving Buprenorphine. The objective was to measure the difference in the patients' general perception and satisfaction of the treatments available. OUD was diagnosed using the Diagnostic and Statistical Manual of Mental Disorders 5th Edition criteria and the level of satisfaction was measured by "Treatment Perceptions Questionnaire (TPQ)."

FINDINGS

The prison group reported significantly lower satisfaction when compared to the community group (total TPQ mean scores: M=34.73, SD =4.12 and M=16.67, SD =4.78, respectively, with t (56.76) =15.68, p=0.000). Furthermore, age, marital status, education level and elapsed time in treatment had no significant interactions with the total TPQ score.

ORIGINALITY/VALUE

The major principles of the ethics of care and evidence-based safe practices will be proposed for the introduction of Buprenorphine to Lebanese prisons. This work provides an opportunity for the expansion of the Lebanese OST program and consequently other countries in the region could benefit from this experience.

The PPARγ Agonist Pioglitazone Fails to Alter the Abuse Potential of Heroin, But Does Reduce Heroin Craving and Anxiety

Possibly through its effects on glia, the peroxisome proliferator-activated gamma receptor (PPARγ) agonist pioglitazone (PIO) has been shown to alter the effects of heroin in preclinical models. Until now, these results have not been assessed in humans. Heroin-dependent participants were randomized to either active (45 mg, n = 14) or placebo (0 mg, n = 16) PIO maintenance for the duration of the three-week study. After stabilization on buprenorphine (8 mg), participants began a two-week testing period. On the first to fourth test days, participants could self-administer drug or money by making verbal choices for either option. On the fifth day, active heroin and money were administered and participants could work to receive heroin or money using a progressive ratio choice procedure. Test days 6-10 were identical to test days 1-5 with the exception that, during one of the test weeks, placebo was available on the first four days, and during the other week heroin was available. PIO failed to alter the reinforcing or positive subjective effects of heroin, but it did reduce heroin craving and overall anxiety. Although we were unable to replicate the robust effects found in preclinical models, these data provide an indication of drug effects that deserves further exploration.

Management of Opioid Addiction With Opioid Substitution Treatments: Beyond Methadone and Buprenorphine

With the opioid crisis in North America, opioid addiction has come in the spotlight and reveals the weakness of the current treatments. Two main opioid substitution therapies (OST) exist: buprenorphine and methadone. These two molecules are mu opioid receptor agonists but with different pharmacodynamic and pharmacokinetic properties. In this review, we will go through these properties and see how they could explain why these medications are recognized for their efficacy in treating opioid addiction but also if they could account for the side effects especially for a long-term use. From this critical analysis, we will try to delineate some guidelines for the design of future OST.

Opiate agonist treatment to improve health of individuals with opioid use disorder in Lebanon

BACKGROUND

Opioid agonist therapy has been widely used to reduce harms among individuals with opioid use disorder but its effectiveness has not been evaluated in the Middle East North African (MENA) region. This study aims to evaluate the effectiveness of a program using opioid agonist therapy in combination with psychosocial support on improving psychological and social well-being, reducing arrest, and reducing risky behavior in individuals with opioid use disorder in Lebanon.

METHODS

A one-group pre-test post-test design study was performed at SKOUN Lebanese Addiction Centre between January 2013 and December 2014. Eighty-six out of 181 patients agreed to participate and completed the 3-month assessment and 38 concluded the 12-month assessment. Psychological (depression and anxiety, quality of life), substance dependence/abuse, behavioral (injecting behavior, sharing needles and paraphernalia), and social outcomes were evaluated at baseline, 3, and 12 months post-treatment.

RESULTS

Remarkable statistical significance improvements were observed 3 months after treatment in most outcome variables including quality of life, anxiety, substance dependence, overdose, employment, and injecting behavior. Improvements were sustained 12 months after treatment.

CONCLUSION

Results support expanding the access to opioid agonist therapy in other MENA countries to treat substance dependence and reduce harms among individuals with opioid use disorder.

Chronic hepatitis C and individuals with a history of injecting drugs in Spain: population assessment, challenges for successful treatment

In Spain, there is a need to improve chronic hepatitis C care among people who inject drugs (PWID). Injecting drug use is an important risk behaviour for hepatitis C virus (HCV) infection. Review of 28 sources of the relevant published literature mapped the size of the addiction-HCV population in Spain. Experts in opioid use disorder (OUD) treatment in Spain completed a consensus to define the population size, HCV prevalence and access or barriers to hepatitis C treatment for PWID populations. In Spain, over 300 000 individuals have a lifetime history of injecting drugs. Currently, 150 000 individuals in Spain have OUD; many have injected drugs. Each year, 80 000 individuals engage with treatment services for OUD. A proportion of this group continues to inject drugs. There is a high HCV prevalence in PWID - estimates of 60-80% in Spain. Uptake of hepatitis C therapy in PWID in Spain is limited; barriers include awareness of treatment pathways, advocacy for regular screening and effective joint care. There is an urgent need to address barriers to effective hepatitis C care for PWID in Spain. Practical and specific strategies including peer-led solutions, patient buddy systems and joint working models at the local level can make important short-term differences.
