IntroductionThe global opioid-related disease burden is significant. Opioid agonist treatment (OAT) can be effective in reducing illicit opioid use and fatal overdose, and improving multiple health and social outcomes. Despite evidence for its effectiveness, there are significant deficits in OAT globally. COVID-19 has required rapid adaptation of remote models of healthcare. Telemedicine is not used routinely in OAT, and little is known about the current levels of use and effectiveness. The objective of this review is to describe models of telemedicine and their efficacy.Methods and analysisThis scoping review uses the review methodology described by Arksey and O’Malley and adapted by Levac et al. The search strategy developed by the medical librarian at the Irish College of General Practitioners in conjunction with the research team will involve five databases (PubMed, EMBASE, the Cochrane Library, PsycInfo and OpenGrey) and the hand searching of reference lists. A limited initial search of two databases will be completed to refine search terms, followed by a second comprehensive search using newly refined search terms of all databases and finally hand searching references of included studies. To be included, studies must report on remote ways of providing OAT (including assessment, induction and monitoring) or related psychosocial support; be published in English after 2010. Two researchers will independently screen titles, abstracts and full-text articles considered for inclusion. Data will be extracted onto an agreed template and will undergo a descriptive analysis of the contextual or process-oriented data and simple quantitative analysis using descriptive statistics.Ethics and disseminationResearch ethics approval is not required for this scoping review. The results of this scoping review will inform the development of a national remote model of OAT. The results will be published in peer-reviewed journals and presented at relevant conferences.

Abstract Background A high proportion of people receiving both oral and injectable opioid agonist treatment report concurrent use of stimulants (i.e. cocaine and or amphetamines), which has been associated with higher rates of continued illicit opioid use and treatment dropout. A recent randomized controlled trial demonstrated the effectiveness of dextroamphetamine (a prescribed stimulant) at reducing craving for and use of cocaine among patients receiving injectable opioid agonist treatment. Following this evidence, dextroamphetamine has been prescribed to patients with stimulant use disorder at a clinic in Vancouver. This study investigates perceptions of the effectiveness of dextroamphetamine from the perspective of these patients. Methods Data were collected using small focus groups and one-on-one interviews with patients who were currently or formerly receiving dextroamphetamine (n = 20). Thematic analysis was conducted using an iterative approach, moving between data collection and analysis to search for patterns in the data across transcripts. This process led to the defining and naming of three central themes responding to the research question. Results Participants reported a range of stimulant use types, including cocaine (n = 8), methamphetamine (n = 8), or both (n = 4). Three central themes were identified as relating to participants’ perceptions of the effectiveness of the medication: 1) achieving a substitution effect (i.e. extent to which dextroamphetamine provided a substitution for the effect they received from use of illicit stimulants); 2) Reaching a preferred dose (i.e. speed of titration and effect of the dose received); and 3) Ease of medication access (i.e. preference for take home doses (i.e. carries) vs. medication integrated into care at the clinic). Conclusion In the context of continued investigation of pharmacological treatments for stimulant use disorder, the present study has highlighted how the study of clinical outcomes could be extended to account for factors that contribute to perceptions of effectiveness from the perspective of patients. In practice, elements of treatment delivery (e.g. dosing and dispensation protocols) can be adjusted to allow for various scenarios (e.g. on site vs. take home dosing) by which dextroamphetamine and other pharmacological stimulants could be implemented to provide “effective” treatment for people with a wide range of treatment goals and needs.

Optimal Outcomes

Objective: Studies dating back to 1964 consistently support the effectiveness of methadone as a maintenance treatment for opioid use disorder (OUD), and since 2003, the effectiveness of buprenorphine. Short-term detoxification has not proven to be an effective treatment, as it results in high relapse rates when compared with maintenance treatment with an opioid agonist therapy (OAT). The question about the duration of maintenance treatment for OUD has been debated with recommendations ranging from a minimum of 1 year, 2 years, to indefinitely. Other factors such as misconceptions, regulations, and insurance barriers also have an impact on the duration dilemma of OAT.Design: There were no a priori criteria for article inclusion and this is not a structured literature review. It is a review of articles of convenience from 1964 to 2018.Main outcome measure: This paper aims to address the dilemma of the ideal duration of OAT and to discuss the factors that could affect this decision.Results: Sustained OAT has had significantly better long-term outcomes than short-term detoxification or time limited maintenance. Optimal outcomes are dependent on adequate treatment duration.Conclusions: Addiction is a chronic brain disease and its treatment should be similar to the treatment of other chronic medical and psychiatric diseases. Long-term, sometimes lifetime, continuation of OAT for the treatment of OUD results in optimal outcomes when measuring morbidity and mortality. The accumulated evidence does not support any arbitrary limitation to the duration of OAT.

Opposing Effects

Opioid analgesics are effective pain therapeutics but they cause various adverse effects and addiction. For safer pain therapy, biased opioid agonists selectively target distinct μ opioid receptor (MOR) conformations, while the potential of biased opioid antagonists has been neglected. Agonists convert a dormant receptor form (MOR-μ) to a ligand-free active form (MOR-μ*), which mediates MOR signaling. Moreover, MOR-μ converts spontaneously to MOR-μ* (basal signaling). Persistent upregulation of MOR-μ* has been invoked as a hallmark of opioid dependence. Contrasting interactions with both MOR-μ and MOR-μ* can account for distinct pharmacological characteristics of inverse agonists (naltrexone), neutral antagonists (6β-naltrexol), and mixed opioid agonist-antagonists (buprenorphine). Upon binding to MOR-μ*, naltrexone but not 6β-naltrexol suppresses MOR-μ*signaling. Naltrexone blocks opioid analgesia non-competitively at MOR-μ*with high potency, whereas 6β-naltrexol must compete with agonists at MOR-μ, accounting for ~100-fold lower in vivo potency. Buprenorphine’s bell-shaped dose–response curve may also result from opposing effects on MOR-μ and MOR-μ*. In contrast, we find that 6β-naltrexol potently prevents dependence, below doses affecting analgesia or causing withdrawal, possibly binding to MOR conformations relevant to opioid dependence. We propose that 6β-naltrexol is a biased opioid antagonist modulating opioid dependence at low doses, opening novel avenues for opioid pain therapy and use management.

ABSTRACTBackgroundOpioid use disorder is a major public health crisis, and evidence suggests ways of better serving patients who live with opioid use disorder in the emergency department (ED). A multi-disciplinary team developed a quality improvement project to implement this evidence.MethodsThe intervention was developed by an expert working group consisting of specialists and stakeholders. The group set goals of increasing prescribing of buprenorphine/naloxone and providing next day walk-in referrals to opioid use disorder treatment clinics. From May to September 2018, three Alberta ED sites and three opioid use disorder treatment clinics worked together to trial the intervention. We used administrative data to track the number of ED visits where patients were given buprenorphine/naloxone. Monthly ED prescribing rates before and after the intervention were considered and compared with eight nonintervention sites. We considered whether patients continued to fill opioid agonist treatment prescriptions at 30, 60, and 90 days after their index ED visit to measure continuity in treatment.ResultsThe intervention sites increased their prescribing of buprenorphine/naloxone during the intervention period and prescribed more buprenorphine/naloxone than the controls. Thirty-five of 47 patients (74.4%) discharged from the ED with buprenorphine/naloxone continued to fill opioid agonist treatment prescriptions 30 days and 60 days after their index ED visit. Thirty-four patients (72.3%) filled prescriptions at 90 days.ConclusionsEmergency clinicians can effectively initiate patients on buprenorphine/naloxone when supports for this standardized evidence-based care are in place within their practice setting and timely follow-up in community is available.

Abstract Background A minority of patients with opioid use disorder are treated for hepatitis C virus infection (HCV). While colocated HCV and opioid agonist therapy (OAT) along with harm reduction can facilitate prevention and cascade to cure, there are few real-world examples of such embedded care models in the United States in the direct-acting antiviral (DAA) era. Methods We conducted a retrospective chart review to determine sustained virologic response (SVR) and reinfection rates during the first 5-year period of DAA availability among individuals tested and treated on-site at Rhode Island’s only nonprofit methadone maintenance program. Results Of 275 who initiated DAAs, the mean age (range) was 43 (22–71) years, 34.5% were female, 57.5% had genotype 1a, 23.3% had cirrhosis, and 92% were Medicaid recipients. SVR was 85.0% (232/273), while modified intent-to-treat SVR was 93.2% (232/249); 17 patients did not achieve SVR, 2 awaited SVR 12 weeks post-end-of-treatment, and 24 were lost to follow-up. Thirty reinfections were identified over 375.5 person-years of follow-up (rate, 7.99/100 person-years). The median time to first reinfection (interquartile range) was 128 (85.25–202.5) days. Before July 1, 2018, 72 patients accessed DAAs over 3.7 years; after Medicaid DAA restrictions were lifted, 109 patients accessed DAAs over 1.3 years. The Prior Authorization (PA) process requires many steps, differing across 11 RI insurers, taking 45–120 minutes per patient. Conclusions DAA treatment was effective among a marginalized population in an urban colocated OAT/HCV program. Removing DAA restrictions facilitates treatment initiation. The PA process remains a modifiable barrier to expanding capacity in the United States.
