    Time to confront iatrogenic opioid addiction
    (Rogers Publishing Healthcare Group, 2016-05)
    Canada has been grappling for decades in a largely ineffective attempt to keep heroin out of our borders. Now the unsafe prescribing of opioids has organized crime groups turning their attention to customers whose addiction started in the doctor's office. Physicians are going to have to face the tough conversations that involve two of the hardest words in a doctor's vocabulary: enough and no.

    Exploring healthcare professionals experience and attitudes towards screening for and treatment of problem alcohol use among drug users attending primary care
    Problem alcohol use (PAU) is common among drug users (DUs) prevalence rates vary from 13-76%, in a recent Irish study of patients on methadone 35% had an AUDIT score indicating PAU. PAU is associated with adverse health outcomes including physical, psychological and social implications. Despite the crucial role of primary care in screening and treatment for problematic alcohol use and the importance of a stepped approach to alcohol treatment, supported by the evidence, little data reporting intervention interventions which address this issue in DUs attending primary care has been reported. This study has examined healthcare professionals’ experience of and attitudes towards screening and treatment for PAU among drug users in primary care. Twelve GPs and practice nurses who were recruited through the central treatment list participated in this study. Qualitative interviews exploring their experiences of and attitudes towards management of PAU in DUs attending primary care were conducted according to a semi structured interview guide. The topic guide was informed by the results of a literature review completed in the previous phase of our research project. Interviews were audio-recorded and subsequently transcribed by external transcribers. For the purpose of this presentation, we have analysed only sections of the interviews concerning strategies that could facilitate implementation of alcohol interventions in primary care settings. Thematic analysis was utilized to analyse these interview sections. Analysis of the selected interview sections revealed that Doctors and Nurses would prefer additional staff to be available in order to support successful implementation of alcohol screening and brief intervention within their practices. They rated this strategy as the most helpful from a list of strategies provided by the interviewers. The results of this preliminary analysis pointed to the importance of professionals trained in the delivery of brief interventions as a necessary adjunct to the optimal provision of drug treatment in general practice. This finding supports the evidence showing that implementation of evidence based interventions to vulnerable populations attending primary care needs to be preceded by identification of potential obstacles at the implementation onset. Further implications of our findings for clinical practice and policy planning will be discussed in the presentation.

    What are the training needs of early career professionals in addiction medicine? A BEME scoping review protocol
    Background: Substance use disorders (SUD) represent a significant social and economic burden globally. Accurate diagnosis and treatment by early career professionals in addiction medicine (ECPAM) fails, in part, due to a lack of training programs targeting this career stage. Prior research has highlighted the need to assess the specific training needs of early career professionals working in this area. Aim: To conduct a scoping review of the literature on the self-reported training needs of ECPAM worldwide. Methods: Medical and education databases will be searched for studies reporting perceived training needs of early career professionals (having completed their training within a five year period at the time of assessment) in addiction medicine. Retrieved citations will be screened and full text articles reviewed for eligibility by two independent reviewers. A third reviewer will arbitrate where there was disagreement. Two reviewers will independently extract data from included studies and conduct a quality appraisal assessment. Importance: Overall, the evidence on the training needs from this review will inform efforts to optimise ECPAM education internationally. Training needs assessment of early career professionals working in the field of addiction medicine is a priority.

    What Are the Self-Assessed Training Needs of Early Career Professionals in Addiction Medicine? A BEME Focused Review
    (Association for Medical Education in Europe (AMEE), 2020-04-03) ; ; ; ; ;
    Background: Substance use disorders represent a significant social and economic burden globally. Accurate diagnosis and treatment by early career professionals in addiction medicine (ECPAM) falls short, in part, due to a lack of training programmes targeting this career stage. Prior research has highlighted the need to assess the specific training needs of ECPAM. Therefore, this focused review assessed self-reported training needs of ECPAM. Methods: Medical and medical education databases (Medline, EMBASE, CINAHL, ERIC, PSYCHInfo, BEI, and AEI) were searched to June 2018 for studies reporting self-reported training needs of ECPAM (trained at most five years before assessment occurred). Retrieved citations were screened for eligibility; two independent researchers reviewed included studies, assessed quality and extracted data. Experts reviewed study findings. Results: Of 1364 identified records, three cross-sectional studies were included, originating from China, USA and England. All studies surveyed ECPAM using self-reported questionnaires, with one study including face-to-face interviews. Participants included residents, physicians and social workers. All studies had a low risk of bias, and reported a wide range of training needs including rehabilitation, relapse prevention, buprenorphine treatment and risk assessment. Conclusions: There is little evidence for and substantial heterogeneity of training needs of ECPAM found in this review, particularly at the level of skills and knowledge. Study quality varies greatly. ECPAM training needs assessments are a priority.

    Strategies to Identify Patient Risks of Prescription Opioid Addiction When Initiating Opioids for Pain
    (American Medical Association (AMA), 2019-05-03) ; ; ;
    Importance: Although prescription opioid use disorder is associated with substantial harms, strategies to identify patients with pain among whom prescription opioids can be safely prescribed have not been systematically reviewed. Objective: To review the evidence examining factors associated with opioid addiction and screening tools for identifying adult patients at high vs low risk of developing symptoms of prescription opioid addiction when initiating prescription opioids for pain. Data Sources: MEDLINE and Embase (January 1946 to November 2018) were searched for articles investigating risks of prescription opioid addiction. Study Selection: Original studies that were included compared symptoms, signs, risk factors, and screening tools among patients who developed prescription opioid addiction and those who did not. Data Extraction and Synthesis: Two investigators independently assessed quality to exclude biased or unreliable study designs and extracted data from higher quality studies. The Preferred Reporting Items for Systematic Reviews and Meta-analyses of Diagnostic Accuracy Studies (PRISMA-DTA) reporting guideline was followed. Main Outcomes and Measures: Likelihood ratios (LRs) for risk factors and screening tools were calculated. Results: Of 1287 identified studies, 6 high-quality studies were included in the qualitative synthesis and 4 were included in the quantitative synthesis. The 4 high-quality studies included in the quantitative synthesis were all retrospective studies including a total of 2 888 346 patients with 4470 cases that met the authors’ definitions of prescription opioid addiction. A history of opioid use disorder (LR range, 17-22) or other substance use disorder (LR range, 4.2-17), certain mental health diagnoses (eg, personality disorder: LR, 27; 95% CI, 18-41), and concomitant prescription of certain psychiatric medications (eg, atypical antipsychotics: LR, 17; 95% CI, 15-18) appeared useful for identifying patients at high risk of opioid addiction. Among individual findings, only the absence of a mood disorder (negative LR, 0.50; 95% CI, 0.45-0.52) was associated with a lower risk of opioid addiction. Despite their widespread use, most screening tools involving combinations of questions were based on low-quality studies or, when diagnostic performance was assessed among high-quality studies, demonstrated poor performance in helping to identify patients at high vs low risk. Conclusions and Relevance: While a history of substance use disorder, certain mental health diagnoses, and concomitant prescription of certain psychiatric medications appeared useful for identifying patients at higher risk, few quality studies were available and no symptoms, signs, or screening tools were particularly useful for identifying those at lower risk.

    General practitioners tackle complex addictions: how complex interventions can assist in dealing with addiction
    (Cambridge University Press, 2016-08-30)
    Substance use disorder treatment is a complex problem. Complex problems require complex interventions, ideally tested via randomised controlled trials. Complex interventions are best developed in stages, using established implementation frameworks. Starting with a historical patient case study, we explore how treatment of this challenging population group has been approached, how an evidence-based framework has informed formulation of a complex health intervention and how this has been progressed via the U.K.'s Medical Research Council (MRC) approach.

    Medication-assisted treatment for youth with opioid use disorder: Current dilemmas and remaining questions
    (Taylor & Francis, 2017-11-30) ; ; ;
    The prevalence of risky opioid use, opioid use disorder, and related harms continue to rise among youth (adolescents and young adults age 15-25) in North America. With an increasing number of opioid overdoses, there remain significant barriers to care for youth with opioid use disorder, and there is an urgent need to expand evidence-based care for treatment of opioid use disorder among this population. Based on the extensive literature on treatment of opioid use disorder among adults, medicated-assisted treatment is likely to be an important or even essential component of treatment of opioid use disorder for most youth. In this article, we outline the current dilemmas and questions regarding the use of medication-assisted treatment among youth with opioid use disorder and propose some potential solutions based on the current evidence.

    Alcohol Use among Persons on Methadone Treatment
    (Lippincott, Williams and Wilkins, 2016) ; ; ;
    We read with interest Dr Varshney et al.'s article on brief interventions for alcohol use among persons on maintenance treatment published ahead-of-print on August 11, 2015. While alcohol is found in the majority of drug-related deaths that involve illicit drugs, around the globe, maintenance therapy with methadone (MMT), or buprenorphine, reduces morbidity and mortality among people who use opiates. Although one common clinical challenge is comorbid alcohol use and opioid use disorder, with guidelines often recommending withholding methadone in this context given the potential for fatal overdose due to drug interactions, alcohol's impact on the health outcomes of MMT patients has been 'overlooked and underestimated'. Therefore, we examined the impact of heavy alcohol use on mortality among MMT patients.

    Eligibility for heroin-assisted treatment (HAT) among people who inject opioids and are living with HIV in a Canadian setting
    Objectives: A growing body of evidence supports the effectiveness of injectable diacetylmorphine (i.e., heroin) for individuals with treatment-refractory opioid use disorder. Despite this evidence, and the increasing toll of opioid-associated morbidity and mortality, it remains controversial in some settings. To investigate the possible contribution of heroin-assisted treatment (HAT) to HIV treatment-related outcomes, we sought to estimate the proportion and characteristics of HIV-positive people who inject opioids that might be eligible for HAT in Vancouver, Canada. Methods: We used data from a prospective cohort of people living with HIV who use illicit drugs in Vancouver, Canada. Using generalized estimating equations (GEE), we assessed the longitudinal relationships between eligibility for HAT, using criteria from previous clinical trials and guidelines, with behavioural, social, and clinical characteristics. Results: Between 2005 and 2014, 478 participants were included in these analyses, contributing 1927 person-years of observation. Of those, 94 (19.7%) met eligibility for HAT at least once during the study period. In a multivariable GEE model, after adjusting for clinical characteristics, being eligible for HAT was positively associated with homelessness, female gender, high-intensity illicit drug use, drug dealing and higher CD4 count. Conclusions: In our study of HIV-positive people with a history of injection drug use, approximately 20% of participants were eligible for HAT at ≥ 1 follow-up period. Eligibility was linked to risk factors for sub-optimal HIV/AIDS treatment outcomes, such as homelessness and involvement in the local illicit drug trade, suggesting that scaling-up access to HAT might contribute to achieving optimal HIV treatment in this setting.

    Factors associated with discontinuation of methadone maintenance therapy (MMT) among persons who also use alcohol in Vancouver, Canada
    Background We sought to examine the factors associated with discontinuation of MMT among persons on methadone who use alcohol. Methods We evaluated the impact of drug-related and other factors on discontinuation of MMT among persons enrolled in MMT and who reported any use of alcohol versus those who were enrolled in two community-recruited prospective cohorts of people who use illicit drugs (PWUD). Extended Cox models with time-dependent variables identified factors independently associated with time to first MMT discontinuation. Results Between December 2005 and 2015, 823 individuals on MMT who also reported using alcohol at least once were included in these analyses. During the study period, 391 (47.5%) discontinued methadone. Daily heroin injection (Adjusted Hazard Ratio [AHR] = 2.67, 95% Confidence Interval [CI]: 2.10–3.40) and homelessness (AHR = 1.42, 95% CI: 1.10–1.83) were positively associated with MMT discontinuation, whereas receiving other concurrent addiction treatment in addition to MMT (AHR = 0.07, 95% CI: 0.05–0.08), as well as >60 mg methadone dose (AHR = 0.48, 95% CI: 0.39–0.60), Hepatitis C virus seropositivity (AHR = 0.65, 95% CI: 0.47–0.90), and HIV seropositivity (AHR = 0.72, 95% CI: 0.57–0.91) were negatively associated with MMT discontinuation. Any/heavy alcohol use was not independently associated with MMT discontinuation. Conclusions This study reinforces the known risks of continued heroin injection and homelessness for MMT discontinuation among individuals who also consume alcohol and highlights the protective effect of both MMT dose and receipt of concurrent addiction treatment.
