Methadone, buprenorphine and preferences for opioid agonist treatment: A qualitative analysis

Prescribing of extended release buprenorphine injection for Medicaid beneficiaries, 2018-2022

BACKGROUND AND AIMS

Extended release buprenorphine injection (INJ-BUP) has been available in the United States since 2018. INJ-BUP has the potential to positively impact opioid use disorder (OUD) treatment outcomes by providing additional treatment options . As one of the largest payers of OUD treatment in the US, Medicaid coverage is important for access and uptake of INJ-BUP. Uptake of INJ-BUP among Medicaid beneficiaries has not been described since 2019 and variation in uptake by state has not previously been explored. We aimed to measure prescribing of INJ-BUP for Medicaid beneficiaries since 2018, nationwide and by state.

METHODS

We analyzed State Drug Utilization Data from 2017 to 2022 and calculated the number of prescription fills for INJ-BUP and oral buprenorphine paid by Medicaid. To compare across states, we calculated the number of prescription fills per 100 Medicaid beneficiaries treated for OUD using data from Transformed Medicaid Statistical Information System Substance Use Disorder (T-MSIS SUD) Data Books. Data sources are publicly available.

RESULTS

The number of prescription fills for INJ-BUP paid by Medicaid increased from 4322 (0.1% of all buprenorphine prescription fills) in 2018 to 186 861 (2.0%) in 2022. Each year the increase in fills exceeded the prior year change, indicating accelerating uptake. There was notable variability across states.

CONCLUSIONS

The number of extended release buprenorphine injection prescriptions among US Medicaid beneficiaries treated for opioid use disorder increased from over 4000 prescriptions in 2018 to over 185 000 in 2022 but uptake is much less than observed in other countries over shorter time periods.

Spatial inequities in access to medications for treatment of opioid use disorder highlight scarcity of methadone providers under counterfactual scenarios

Access to treatment and medication for opioid use disorder (MOUD) is essential in reducing opioid use and associated behavioral risks, such as syringe sharing among persons who inject drugs (PWID). Syringe sharing among PWID carries high risk of transmission of serious infections such as hepatitis C and HIV. MOUD resources, such as methadone provider clinics, however, are often unavailable to PWID due to barriers like long travel distance to the nearest methadone provider and the required frequency of clinic visits. The goal of this study is to examine the uncertainty in the effects of travel distance in initiating and continuing methadone treatment and how these interact with different spatial distributions of methadone providers to impact co-injection (syringe sharing) risks. A baseline scenario of spatial access was established using the existing locations of methadone providers in a geographical area of metropolitan Chicago, Illinois, USA. Next, different counterfactual scenarios redistributed the locations of methadone providers in this geographic area according to the densities of both the general adult population and according to the PWID population per zip code. We define different reasonable methadone access assumptions as the combinations of short, medium, and long travel distance preferences combined with three urban/suburban travel distance preference. Our modeling results show that when there is a low travel distance preference for accessing methadone providers, distributing providers near areas that have the greatest need (defined by density of PWID) is best at reducing syringe sharing behaviors. However, this strategy also decreases access across suburban locales, posing even greater difficulty in regions with fewer transit options and providers. As such, without an adequate number of providers to give equitable coverage across the region, spatial distribution cannot be optimized to provide equitable access to all PWID. Our study has important implications for increasing interest in methadone as a resurgent treatment for MOUD in the United States and for guiding policy toward improving access to MOUD among PWID.

The role of attachment and personality traits in choosing opiate addiction replacement therapy

Contemporary medical approaches for opioid addiction often include medication-assisted therapy, utilizing methadone and buprenorphine. However, factors influencing patient preferences for starting buprenorphine or methadone therapy are poorly understood. This study aims to explore whether variances in personality traits and attachment styles are related to treatment preferences among individuals undergoing buprenorphine and methadone maintenance therapies. 300 participants completed the Big Five Questionnaire for personality traits and sub-dimensions and the Experiences in Close Relationship Scale for assessing attachment styles. The results indicated that patients with higher levels of Dynamism, Conscientiousness, and Perseverance personality traits were more likely to choose buprenorphine over methadone for achieving and maintaining abstinence. Although attachment styles showed a greater ability to differentiate between groups compared to personality traits, the differences were not significant. However, Conscientiousness stood out for its high discriminant validity, suggesting that scores in this personality dimension could significantly distinguish between groups, with individuals in the buprenorphine group showing higher levels of Conscientiousness compared to the methadone group. The study suggests a partial association between individuals' preference for abstinence therapy and their personality traits. These findings could be considered useful indicators when choosing maintenance therapy to help opiate-addicted patients achieve and maintain abstinence.

Reduced emergency department use among insured individuals receiving extended-release buprenorphine in a health system setting

Introduction

Extended-release buprenorphine (XR-Bup) is associated with reduced opioid use and opioid negative urine drug screens. Little is known about its use in outpatient addiction care provided within health systems.

Methods

Individuals prescribed XR-Bup were identified from electronic health records; chart abstraction was conducted. Primary outcome was all-cause emergency department (ED) use. Secondary outcomes included ED use or inpatient stays for mental health or substance use, ED use for any other cause, discontinuation reasons, and drug substitution. Statistical comparisons used nonparametric tests from related samples (McNemar's test and Wilcoxon matched pair tests) to test outcomes six months prior and 6 months following XR-Bup initiation.

Results

152 individuals had an XR-Bup order, 126 received >1 injection. Among those consistently insured 6 months prior to and following XR-Bup initiation (n=99), the mean number of injections following initiation was 3.95; one-third received 6 doses in the 6 months. The proportion of individuals using ED services for all causes declined (41% prior vs. 28% following XR-Bup initiation, p<.05); similar results were found for secondary ED use outcomes. The proportion of individuals requiring inpatient treatment for mental health or substance use also declined (46% vs. 16%, p<.01). Common reasons for discontinuing XR-Bup included losing insurance (21%) or cost (11%). The most common non-prescribed substances used during treatment were opioids (n=31) and THC (n=20).

Conclusions

In this non-randomized retrospective observational study, use of XR-Bup was associated with reduced ED use 6 months following initiation. XR-Bup may help health systems reduce use of costly ED services.

A population-based time-series analysis of opioid agonist treatment dispensed during pregnancy

BACKGROUND AND AIMS

Identifying effective opioid treatment options during pregnancy is a high priority due to the growing prevalence of opioid use disorder across North America. We assessed the temporal impact of three population-level interventions on the use of opioid agonist treatment (OAT) during pregnancy in Ontario, Canada.

DESIGN

This was a population-based time-series analysis to identify trends in the monthly prevalence of pregnant people dispensed methadone and buprenorphine. The impact of adding buprenorphine/naloxone to the public drug formulary, the release of pregnancy-specific guidance and the start of the COVID-19 pandemic were assessed.

SETTING AND PARTICIPANTS

The study was conducted in Ontario, Canada between 1 July 2013 and 31 March 2022, comprising people who delivered a live or stillbirth in any Ontario hospital during the study period.

MEASUREMENTS

We identified any prescription for methadone or buprenorphine dispensed between the estimated conception date and delivery date and calculated the monthly prevalence of OAT-exposed pregnancies among all pregnant people in Ontario.

FINDINGS

Overall, rates of OAT during pregnancy have declined since mid-2018. Methadone-exposed pregnancies decreased from 0.46% of all pregnancies in Ontario in 2015 to a low of 0.16% in 2022. In the primary analysis, none of the interventions had a statistically significant impact on overall OAT rates; however, in the stratified analyses, there was a small increase in buprenorphine after the formulary change [0.006%, 95% confidence interval (CI) = 0.0032-0.0081, P < 0.0001] and a decrease in buprenorphine after the release of the 2017 guidelines (-0.005%, 95% CI = -0.0080 to -0.0020, P = 0.001) and the start of the COVID-19 pandemic (-0.003%, 95% CI = -0.0054 to -0.0006, P = 0.015).

CONCLUSION

Despite changes in guidance and funding, opioid agonist treatment during pregnancy has been declining in Ontario, Canada since 2018.

Cost-effectiveness of full and partial opioid agonists for opioid use disorder in outpatient settings: United States healthcare sector perspective

INTRODUCTION

Studies show that medications for opioid use disorder (MOUD) reduce illicit opioid use, emergency healthcare services, opioid-related overdose, and death. However, few studies have investigated the long-term cost-effectiveness of MOUD in office-based opioid treatment (OBOT) and opioid treatment program (OTP) settings. We aimed to estimate the cost, utility, quality-adjusted life years gained (QALYs), and incremental cost-effectiveness ratios (ICERs) of three MOUD compared to each other and counseling without medication from a US healthcare sector perspective.

METHODS

Our study developed a Markov model to conduct a cost-effectiveness analysis of counseling and three MOUD in the OBOT and OTP settings: sublingual buprenorphine/naloxone (BUPNX), buprenorphine extended-release (XR-BUP) injection, and oral methadone. The model included five health states representing combinations of receiving or off treatment while either using or not actively using illicit opioids, and death. The cycle length was one month; the time-horizon was ten years. The study obtained model inputs from systematic reviews of published literature and public data. A 3 % annual discount rate was applied to cost and utility calculation. The primary outcomes included total costs, life-years (LYs), QALYs, and ICERs. We also conducted a scenario analysis using a hypothetical OBOT outpatient setting with methadone.

RESULTS

In the base-case OBOT setting, the total costs and QALYs, respectively, were counseling $22,848, 5.60; BUPNX $29,875, 5.82; and XR-BUP $63,936, 5.87. ICERs were $32,345/QALY (BUPNX vs. counseling) and $625,858/QALY (XR-BUP vs BUPNX). In the OTP setting, the total costs of counseling, methadone, BUPNX, and XR-BUP were $20,124, $27,000, $33,500, and $75,272, respectively. QALYs of methadone were 5.86. QALYs of counseling, BUPNX, and XR-BUP remained the same as in the OBOT setting. Incremental ICERs were $26,714/QALY (methadone vs counseling) and $3,337,623/QALY (XR-BUP vs methadone). BUPNX was dominated by methadone. In the scenario analysis, BUPNX was also dominated by methadone.

CONCLUSIONS

Outpatient MOUD resulted in important gains in quality of life and life expectancy. In both OBOT and OTP settings, XR-BUP was not cost-effective. BUPNX was cost-effective in the OBOT setting, while it was dominated by methadone in the OTP setting. The cost-effectiveness of BUPNX and XR-BUP could be enhanced if the costs of these medications were reduced.

Dialing for doctors: Secret shopper study of Arizona methadone and buprenorphine providers, 2022

INTRODUCTION

Methadone and buprenorphine are effective and safe treatments for opioid use disorder (OUD) and also reduce overdose and all-cause mortality. Identifying and reaching providers of medication for opioid use disorder (MOUD) has proven difficult for prospective patients and researchers.

OBJECTIVES

To assess the accuracy of government-maintained lists of Arizona (AZ) providers prescribing MOUD, and the extent to which these providers are accessible for treatment.

METHODS

A two-phase study used a listing of 2376 AZ MOUD providers obtained from the U.S. Drug Enforcement Administration and the Substance Abuse and Mental Health Services Administration. Phase 1 assessed the accuracy of the listing using internet confirmatory research from May-October 2022. Phase 2 used the resulting list of 838 providers to assess provider availability, type of MOUD treatment provided, and accepted payment through secret shopper calls between November 16 and 30, 2022.

RESULTS

Just over half (52.2 %, n = 1240) of providers were removed from the original listing during Phase 1. One quarter (25.9 %) were no longer in practice. Among the 833 eligible for the secret shopper Phase 2 study, 36.6 % (n = 307) were reached and identified as providing MOUD. A vast majority (88.1 %) of MOUD providers indicating treatment type were accepting new patients, however methadone was identified far more frequently than was likely permitted or provided for OUD. Providers were 5.5 times more likely to accept new patients if they accepted cash payment for services, and 4.9 times more likely if they accepted Medicaid. Rural areas remained underserved.

CONCLUSIONS

The active population of MOUD providers is far smaller than surmised. DEA and SAMHSA provider listings are not sufficiently accurate for survey research sampling. Other means of representative sampling will need to be devised, and trusted lists of providers for prospective patients should be promoted, publicly available, and regularly maintained for accuracy. Providers that offer treatment should assure that public-facing staff have basic information about the practice, the treatment offered, and conditions for taking new patients. Concerted efforts must assure rural access at the most local levels to reduce patient travel burden.

Inpatient opioid withdrawal: a qualitative study of the patient perspective

Opioid withdrawal is common among hospitalized patients. Those with substance use disorders exhibit higher rates of patient-directed discharge. The literature lacks information regarding the patient perspective on opioid withdrawal in the hospital setting. In this study, we aimed to capture the patient-reported experience of opioid withdrawal during hospitalization and its impact on the desire to continue treatment for opioid use disorder after discharge. We performed a single-center qualitative study involving semi-structured interviews of hospitalized patients with opioid use disorder (OUD) experiencing opioid withdrawal. Investigators conducted in-person interviews utilizing a combination of open-ended and dichotomous questions. Interview transcripts were then analyzed with open coding for emergent themes. Nineteen interviews were performed. All participants were linked to either buprenorphine (79%) or methadone (21%) at discharge. Eight of nineteen patients (42%) reported a patient-directed discharge during prior hospitalizations. Themes identified from the interviews included: (1) opioid withdrawal was well-managed in the hospital; (2) patients appreciated receiving medication for opioid use disorder (MOUD) for withdrawal symptoms; (3) patients valued and felt cared for by healthcare providers; and (4) most patients had plans to follow-up for opioid use disorder treatment after hospitalization. In this population with historically high rates of patient-directed discharge, patients reported having a positive experience with opioid withdrawal management during hospitalization. Amongst our hospitalized patients, we observed several different individualized MOUD induction strategies. All participants were offered MOUD at discharge and most planned to follow-up for further treatment.

Barriers and facilitators for family physicians prescribing opioid agonist therapy in Saskatchewan

OBJECTIVE

To explore barriers and facilitators for family physicians in Saskatchewan prescribing opioid agonist therapy (OAT).

DESIGN

Self-administered postal survey.

SETTING

Family medicine practices in Saskatchewan.

PARTICIPANTS

A total of 218 Saskatchewan family physicians who were not authorized to prescribe OAT as of June 2022.

MAIN OUTCOME MEASURES

Descriptive and inferential statistics of physicians' self-reported barriers to and facilitators of prescribing OAT for opioid use disorder (OUD).

RESULTS

Most respondents (84.8%) had some comfort with diagnosing OUD. However, more than half (58.3%) did not feel confident or knowledgeable about prescribing OAT. Barriers to OAT prescribing included lack of time, incomplete training requirements, lack of interest, insufficient funding or support, feeling overwhelmed, and perceiving that OAT does not work and thus is not necessary. Physicians working in core neighbourhoods and those receiving fee-for-service compensation reported the least available time to prescribe OAT. Conversely, physicians working in interdisciplinary team settings had increased time for OAT prescribing compared with physicians in other settings. Having a close personal relationship with someone with OUD was correlated with increased comfort in diagnosing OUD as well as with knowledge about and confidence in prescribing OAT. Themes identified as facilitators to increasing OAT prescribing included the addition of resources and supports, increased training, more awareness about OUD and OAT, enhanced compensation, and altered prescribing regulations.

CONCLUSION

Despite the presence of several real and perceived barriers limiting OAT prescribing by Saskatchewan family physicians, there are family physicians interested in providing this therapy. Increased clinical resources and support, including increased interdisciplinary practice, are actionable steps that should be considered by policy decision makers to address this issue. Additionally, increased OUD and OAT education, which includes the perspectives of those with lived experience of OUD, would help address physician confidence, knowledge, and awareness in this area.

Low-dose buprenorphine initiation and treatment continuation among hospitalized patients with opioid dependence: A retrospective cohort study

BACKGROUND

Buprenorphine is an effective treatment for both opioid use disorder (OUD) and chronic pain, but buprenorphine's pharmacology complicates treatment initiation for some patients. Low-dose buprenorphine initiation is a novel strategy that may reduce precipitated withdrawal. Few studies describe what patient populations benefit most from low-dose initiations and the clinical parameters that impact treatment continuation. This study aimed to 1) describe experiences with low-dose buprenorphine initiation, including both successes and failures among hospitalized patients in an urban underserved community; 2) identify patient- and treatment-related characteristics associated with unsuccessful initiation and treatment discontinuation; and 3) assess buprenorphine treatment continuation after discharge.

METHODS

This is a retrospective cohort study with opioid-dependent (meaning OUD or receiving long-term opioid therapy for chronic pain) patients who underwent low-dose buprenorphine initiation during hospital admission from October 2021 through April 2022. The primary outcome was successful completion of low-dose initiation. Bivariate analysis identified patient- and treatment-related factors associated with unsuccessful initiation. Secondary outcomes were buprenorphine treatment discontinuation at post-discharge follow-up, 30- and 90-days.

RESULTS

Of 28 patients who underwent low-dose buprenorphine initiation, 68 % successfully completed initiation. Unsuccessful initiation was associated with receipt of methadone during admission and higher morphine milligram equivalents (MME) of supplemental opioids. Of 22 patients with OUD, the percent receiving a buprenorphine prescription at a follow-up visit, 30 days, and 90 days, respectively, was 46 %, 36 %, and 36 %. Of 6 patients with chronic pain, the percent receiving a buprenorphine prescription at a follow-up visit, 30 days, and 90 days, respectively, was 100 %, 100 %, and 83 %.

CONCLUSION

Low-dose buprenorphine initiation can be successful in opioid-dependent hospitalized patients. Patients taking methadone or requiring higher MME of supplemental opioids may have more difficulty with the low-dose buprenorphine initiation approach, but these findings should be replicated in larger studies. This study suggests patient- and treatment-related factors that clinicians could consider when determining the optimal treatment strategy for patients wishing to transition to buprenorphine.

Effects of a Two-Month Exercise Training Program on Concurrent Non-Opiate Substance Use in Opioid-Dependent Patients during Substitution Treatment

BACKGROUND

This randomized controlled trial aimed to evaluate the effects of a two-month exercise intervention on the concurrent non-opiate substance use (alcohol, cocaine, cannabis, and benzodiazepines) in opioid users during their medication treatment.

METHODS

Ninety opioid users (41 females) in methadone and buprenorphine medication treatment were randomly divided into four groups: (a) buprenorphine experimental (BEX; n = 26, aged 41.9 ± 6.1 yrs); (b) buprenorphine control (BCON; n = 25, aged 41.9 ± 5.6 yrs); (c) methadone experimental (MEX; n = 20, aged 46.7 ± 6.6 yrs); and (d) methadone control (MCON; n = 19, aged 46.1 ± 7.5 yrs). The experimental groups (BEX and MEX) followed an aerobic exercise training program on a treadmill for 20 min at 70% HRmax, 3 days/week for 8 weeks. Socio-demographic, anthropometric, and clinical characteristics, as well as non-opioid drug use in days and quantity per week, were assessed before and after the intervention period.

RESULTS

Following the exercise training, the weekly non-opioid substance consumption (days) decreased (p < 0.05) in both exercise groups and was lower in BEX compared to MEX, while no differences were observed (p > 0.05) between the control groups (BCON vs. MCON) or compared to their baseline levels. Similarly, the daily amount of non-opiate substance intake was reduced (p < 0.05) post-training in BEX and MEX, whereas it did not differ (p > 0.05) in BCON and MCON compared to the baseline.

CONCLUSIONS

The two-month exercise intervention reduced the non-opioid drug use in both the methadone and buprenorphine substitution groups compared to the controls, suggesting that aerobic exercise training may be an effective strategy for treating patients with OUDs.

Loss, liberation, and agency: Patient experiences of methadone treatment at opioid treatment programs during the COVID-19 pandemic

BACKGROUND

Despite its safety and effectiveness, methadone treatment for opioid use disorder (OUD) remains highly stigmatized, and stringent opioid treatment program (OTP) attendance requirements create barriers to retention for many patients. The COVID-19 pandemic prompted a shift in federal regulations governing methadone, including a blanket exemption permitting increased take-home doses of methadone. We studied the impact of these changes upon established patients' experiences of OTP care.

METHOD

We conducted semi-structured qualitative interviews with 18 OTP patients who met our criteria of having established OTP care (i.e., enrolled at the OTP for at least 12 weeks) and were administered methadone three to six days weekly prior to the March 2020 blanket exemption. Interviews centered on how COVID-19 had affected their experiences of receiving treatment at an OTP.

RESULTS

We identified three interconnected themes relevant to transformation of OTP care by the COVID-19 pandemic. Participants described mourning therapeutic OTP relationships and structure (1. loss), yet feeling more satisfaction with fewer in-person OTP visits (2. liberation), and appreciating more opportunities to self-direct their OUD care (3. agency).

DISCUSSION

Structural changes made to OTP care early in the COVID-19 pandemic resulted in loss of community and structure. Increasing the availability of take-home methadone also improved patient experience and sense of agency. Our findings join a diverse body of converging evidence in support of policy changes allowing for more flexible dosing and individualized OTP care.

Patient and Provider Perspectives on Processes of Engagement in Outpatient Treatment for Opioid Use Disorder: A Scoping Review

Effective treatment for opioid use disorder (OUD) is available, but patient engagement is central to achieving care outcomes. We conducted a scoping review to describe patient and provider-reported strategies that may contribute to patient engagement in outpatient OUD care delivery. We searched PubMed and Scopus for articles reporting patient and/or provider experiences with outpatient OUD care delivery. Analysis included: (1) describing specific engagement strategies, (2) mapping strategies to patient-centered care domains, and (3) identifying themes that characterize the relationship between engagement and patient-centered care. Of 3,222 articles screened, 30 articles met inclusion criteria. Analysis identified 14 actionable strategies that facilitate patient engagement and map to all patient-centered care domains. Seven themes emerged that characterize interpersonal approaches to OUD care engagement. Interpersonal interactions between patients and providers play a pivotal role in encouraging engagement throughout OUD treatment. Future research is needed to further evaluate promising engagement strategies.

A qualitative assessment of tablet injectable opioid agonist therapy (TiOAT) in rural and smaller urban British Columbia, Canada: Motivations and initial impacts

BACKGROUND

The evolving and unpredictable unregulated drug market has driven an unprecedented overdose crisis that requires effective intervention. Growing evidence suggests that novel opioid agonist treatments, such as tablet injectable opioid agonist therapy (TiOAT), have potential to prevent overdoses and other drug-related harms. More evidence is needed to characterize their utility in achieving these outcomes. The current article is an analysis of two TiOAT programs implemented in British Columbia, Canada, to assess impact on health and well-being, including overdose risk. Moreover, we explored participants' enrollment goals and if they were achieved.

METHODS

The study employed qualitative methods to evaluate the TiOAT program in two sites between October 2021 and April 2022. We developed a semi-structured interview tool to guide in depth interviews. All interviews (n = 32) took place on teleconference software or in person. Thematic analysis allowed for the emergence of themes associated with TiOAT participation.

RESULTS

Participants discussed various motivations for enrolling in TiOAT, which included gaining financial stability, reducing or eliminating drug use, addressing withdrawal symptoms, wanting to work, and improving social circumstances. An assessment of initial programmatic impacts revealed that many participant-identified motivators were achieved. Participants also reported fewer or no overdoses since starting TiOAT, and many reported switching from injecting to smoking drugs. Some challenges included adequate dosing as evidenced by ongoing withdrawal and pain. Some participants requested additional opioids, such as diacetylmorphine, to aid in reducing illicit drug use.

CONCLUSION

Participants described how TiOAT helped them to achieve many of their goals. Suggested programmatic improvements include enhanced patient-provider co-design with respect to dosing to address ongoing withdrawal and pain. As the unpredictability the unregulated drug market worsens, novel options, such as TiOAT, ought to be implemented broadly to reduce overdose events and improve quality of life for people who use drugs.

Trends in use of medicines for opioid agonist treatment in Australia, 2013-2022

BACKGROUND

There are limited longitudinal data on national patterns of opioid agonist treatment (OAT). This study describes 10-year trends in the sales of OAT medicines in Australia.

METHODS

A descriptive and time-series analysis of methadone, sublingual (SL) buprenorphine (+/-naloxone), and long-acting injectable (LAI) buprenorphine sold in Australia between 2013 and 2022 was performed. Total units sold were converted into an estimate of the number of clients that could be treated over a 28-day period with that amount of medicine ('client-months').

RESULTS

Between January 2013 and December 2022, the estimated number of client-months on: any OAT increased by 50 % to 53,501, methadone decreased (-8.5%), SL buprenorphine increased (+78%), and LAI buprenorphine increased substantially after September 2019. In January 2013, 78 % of OAT client-months received methadone. By December 2022, 48 % received methadone, 26 % SL buprenorphine, and 26 % LAI buprenorphine. Between 2013 to 2022, OAT client-months per capita were highest in the state of New South Wales. Over the study period, greater increases in OAT were observed in very remote areas (88%) compared to major cities (53%). The number of client-months in non-community pharmacy settings remained stable from 2013 to 2019/20, before increasing markedly. The introduction of LAI buprenorphine was associated with an immediate, sustained increase of 1,636 OAT client-months, and further increases of 190 OAT client-months each month.

CONCLUSION

Patterns of OAT have shifted over the last 10-years with buprenorphine (SL/LAI) now the most common OAT used in Australia. The introduction of LAI buprenorphine has expanded OAT access, particularly in non-community pharmacy settings, and in remote areas.

Spatial inequities in access to medications for treatment of opioid use disorder highlight scarcity of methadone providers under counterfactual scenarios

Access to treatment and medication for opioid use disorder (MOUD) is essential in reducing opioid use and associated behavioral risks, such as syringe sharing among persons who inject drugs (PWID). Syringe sharing among PWID carries high risk of transmission of serious infections such as hepatitis C and HIV. MOUD resources, such as methadone provider clinics, however, are often unavailable to PWID due to barriers like long travel distance to the nearest methadone provider and the required frequency of clinic visits. The goal of this study is to examine the uncertainty in the effects of travel distance in initiating and continuing methadone treatment and how these interact with different spatial distributions of methadone providers to impact co-injection (syringe sharing) risks. A baseline scenario of spatial access was established using the existing locations of methadone providers in a geographical area of metropolitan Chicago, Illinois, USA. Next, different counterfactual scenarios redistributed the locations of methadone providers in this geographic area according to the densities of both the general adult population and according to the PWID population per zip code. We define different reasonable methadone access assumptions as the combinations of short, medium, and long travel distance preferences combined with three urban/suburban travel distance preference. Our modeling results show that when there is a low travel distance preference for accessing methadone providers, distributing providers near areas that have the greatest need (defined by density of PWID) is best at reducing syringe sharing behaviors. However, this strategy also decreases access across suburban locales, posing even greater difficulty in regions with fewer transit options and providers. As such, without an adequate number of providers to give equitable coverage across the region, spatial distribution cannot be optimized to provide equitable access to all PWID. Our study has important implications for increasing interest in methadone as a resurgent treatment for MOUD in the United States and for guiding policy toward improving access to MOUD among PWID.

"I thought it was for guys that did needles": Medication perceptions and lay expertise among medical research participants

INTRODUCTION

Although randomized controlled trials (RCTs) examine "objective" indicators of safety and efficacy of investigational drugs, participants may not perceive study medications as neutral entities. Some medications are imbued with social and cultural meaning, such as stigmatized medications for opioid use disorders. Such perceptions surrounding substance use treatments can extend to the research context and shape RCT participants' experiences with and adherence to study medications.

METHODS

Considering these complexities in substance use research, we conducted a nested qualitative study within a multi-site, pragmatic RCT in Canada testing two treatments (methadone versus buprenorphine/naloxone) for opioid use disorder. Between 2017 and 2020, we conducted 115 interviews with 75 RCT participants across five trial sites in British Columbia, Alberta, Ontario, and Quebec.

RESULTS

Using an abductive coding approach, we characterized participants by their previous experience with medication for opioid use disorder and by their exposure to drug culture and drug scenes. Across these experience types, we identified systematic differences around participants' perceptions of the study medications, sources of information and expertise, and medication stigma.

CONCLUSION

Our findings illustrate the critical importance of social context in shaping medication beliefs and study experiences among people who use drugs, with implications for the conduct of future RCTs in substance use.

Removal of Medicaid Prior Authorization Requirements and Buprenorphine Treatment for Opioid Use Disorder

Importance

Buprenorphine treatment for opioid use disorder (OUD) is associated with decreased morbidity and mortality. Despite its effectiveness, buprenorphine uptake has been limited relative to the burden of OUD. Prior authorization (PA) policies may present a barrier to treatment, though research is limited, particularly in Medicaid populations.

Objective

To assess whether removal of Medicaid PAs for buprenorphine to treat OUD is associated with changes in buprenorphine prescriptions for Medicaid enrollees.

Design, Setting, and Participants

This state-level, serial cross-sectional study used quarterly data from 2015 through the first quarter (January-March) of 2019 to compare buprenorphine prescriptions in states that did and did not remove Medicaid PAs. Analyses were conducted between June 10, 2021, and August 15, 2023. The study included 23 states with active Medicaid PAs for buprenorphine in 2015 that required similar PA policies in fee-for-service and managed care plans and had at least 2 quarters of pre- and postperiod buprenorphine prescribing data.

Exposures

Removal of Medicaid PA for at least 1 formulation of buprenorphine for OUD.

Main Outcomes and Measures

The main outcome was number of quarterly buprenorphine prescriptions per 1000 Medicaid enrollees.

Results

Between 2015 and the first quarter of 2019, 6 states in the sample removed Medicaid PAs for at least 1 formulation of buprenorphine and had at least 2 quarters of pre- and postpolicy change data. Seventeen states maintained buprenorphine PAs throughout the study period. At baseline, relative to states that repealed PAs, states that maintained PAs had lower buprenorphine prescribing per 1000 Medicaid enrollees (median, 6.6 [IQR, 2.6-13.9] vs 24.1 [IQR, 8.7-27.5] prescriptions) and lower Medicaid managed care penetration (median, 38.5% [IQR, 0.0%-74.1%] vs 79.5% [IQR, 78.1%-83.5%] of enrollees) but similar opioid overdose rates and X-waivered buprenorphine clinicians per 100 000 population. In fully adjusted difference-in-differences models, removal of Medicaid PAs for buprenorphine was not associated with buprenorphine prescribing (1.4% decrease; 95% CI, -31.2% to 41.4%). For states with below-median baseline buprenorphine prescribing, PA removal was associated with increased buprenorphine prescriptions per 1000 Medicaid enrollees (40.1%; 95% CI, 0.6% to 95.1%), while states with above-median prescribing showed no change (-20.7%; 95% CI, -41.0% to 6.6%).

Conclusions and Relevance

In this serial cross-sectional study of Medicaid PA policies for buprenorphine for OUD, removal of PAs was not associated with overall changes in buprenorphine prescribing among Medicaid enrollees. Given the ongoing burden of opioid overdoses, continued multipronged efforts are needed to remove barriers to buprenorphine care and increase availability of this lifesaving treatment.

The impact of relaxing restrictions on take-home doses during the COVID-19 pandemic on program effectiveness and client experiences in opioid agonist treatment: a mixed methods systematic review

BACKGROUND

The COVID-19 pandemic led to an unprecedented relaxation of restrictions on take-home doses in opioid agonist treatment (OAT). We conducted a mixed methods systematic review to explore the impact of these changes on program effectiveness and client experiences in OAT.

METHODS

The protocol for this review was registered in PROSPERO (CRD42022352310). From Aug.-Nov. 2022, we searched Medline, Embase, CINAHL, PsycInfo, Web of Science, Cochrane Register of Controlled Trials, and the grey literature. We included studies reporting quantitative measures of retention in treatment, illicit substance use, overdose, client health, quality of life, or treatment satisfaction or using qualitative methods to examine client experiences with take-home doses during the pandemic. We critically appraised studies using the Mixed Methods Appraisal Tool. We synthesized quantitative data using vote-counting by direction of effect and presented the results in harvest plots. Qualitative data were analyzed using thematic synthesis. We used a convergent segregated approach to integrate quantitative and qualitative findings.

RESULTS

Forty studies were included. Most were from North America (23/40) or the United Kingdom (9/40). The quantitative synthesis was limited by potential for confounding, but suggested an association between take-home doses and increased retention in treatment. There was no evidence of an association between take-home doses and illicit substance use or overdose. Qualitative findings indicated that take-home doses reduced clients' exposure to unregulated substances and stigma and minimized work/treatment conflicts. Though some clients reported challenges with managing their medication, the dominant narrative was one of appreciation, reduced anxiety, and a renewed sense of agency and identity. The integrated analysis suggested reduced treatment burden as an explanation for improved retention and revealed variation in individual relationships between take-home doses and illicit substance use. We identified a critical gap in quantitative measures of patient-important outcomes.

CONCLUSION

The relaxation of restrictions on take-home doses was associated with improved client experience and retention in OAT. We found no evidence of an association with illicit substance use or overdose, despite the expansion of take-home doses to previously ineligible groups. Including patient-important outcome measures in policy, program development, and treatment planning is essential to ensuring that decisions around take-home doses accurately reflect their value to clients.

Correlates and Patterns in Use of Medications to Treat Opioid Use Disorder in Jail

OBJECTIVES

Little is known about the correlates of use of medications to treat opioid use disorder (MOUD, ie, buprenorphine, methadone, naltrexone) offered in jails. We evaluated the implementation and outcomes of a MOUD program offered by 2 of the first jails nationwide to provide access to such care.

METHODS

We examined use of MOUD among adults with opioid use disorder (n = 347) incarcerated by 2 rural jails in Massachusetts (2018-2021). We examined MOUD transitions from intake to during incarceration. Using logistic regression, we examined factors associated with in-jail use of MOUD.

RESULTS

At jail entry, 48.7% of individuals with opioid use disorder were being treated with MOUD. During incarceration, 65.1% received MOUD, attributable to a 9.2% increase in use of methadone (from 15.9% to 25.1%) and a 10.1% increase in use of buprenorphine (from 28.5% to 38.6%). During incarceration, 32.3% of individuals were continued on the same MOUD from the community, 25.4% were started, 8.9% stopped, and 7.5% switched type. A total of 25.9% entered jail not on any MOUD and were not started on it. Use of MOUD during incarceration was positively associated with having received MOUD in the community (odds ratio, 12.2; 95% confidence interval, 5.8-25.5) and incarceration at site 1 compared with site 2 (OR, 24.6; 95% CI, 10.9-54.4).

CONCLUSIONS

Expanded access to MOUD in jails can engage an at-risk population with treatment. Understanding factors related to this population's use of MOUD may aid efforts to optimize care during incarceration and after community re-entry.

Effects of Buprenorphine/Naloxone and Methadone on Depressive Symptoms in People with Prescription Opioid Use Disorder: A Pragmatic Randomised Controlled Trial

OBJECTIVE

This study aimed to evaluate the effectiveness of flexible take-home dosing of buprenorphine/naloxone (BUP/NX) and methadone standard model of care in reducing depressive symptoms in people with prescription-type opioid use disorder (POUD). This trial also evaluated whether improvements in depressive symptoms were mediated by opioid use.

METHODS

Analyzed data came from the OPTIMA study (clinicaltrials.gov identifier: NCT03033732), a pragmatic randomised controlled trial comparing flexible take-home dosing of BUP/NX and methadone standard model of care for reducing opioid use in people with POUD. A total of 272 participants were recruited in four Canadian provinces. Participants were randomised 1:1 to BUP/NX or methadone. After treatment induction, past two-week opioid use was measured using the Timeline Followback every two weeks for a total of 24 weeks. Depressive symptoms were measured with the Beck Depression Inventory at baseline, weeks 12 and 24.

RESULTS

Both BUP/NX and methadone significantly reduced depressive symptoms at week 12 (aβ ± SE = -3.167 ± 1.233; P < 0.001) and week 24 (aβ ± SE = -7.280 ± 1.285; P < 0.001), with no interaction between type of treatment and time (P = 0.284). Improvements in depressive symptoms were only partially mediated by a reduction in opioid use (proportion mediated = 36.8%; 95% confidence interval = -1.158 to -0.070; P = 0.015).

CONCLUSIONS

BUP/NX and methadone showed similar effectiveness in decreasing comorbid depressive symptoms in people with POUD. This effect was partially explained by a reduction in opioid use. As both treatments seem equally effective, clinicians are encouraged to tailor the selection of OAT to patients' needs and characteristics.

Polydrug use among patients on methadone medication treatment: Evidence from urine drug testing to inform patient safety

AIMS

Patients in methadone medication treatment for opioid use disorder (M-MOUD) typically have a complex history of opioid use, often in combination with other drugs. It is unknown how frequently M-MOUD patients experience persistent substance or polysubstance use. We measured trends in illicit substance use in a large, multistate population of M-MOUD patients and persistence of substance use in the first year of treatment.

DESIGN

Retrospective cohort study of United States (US) M-MOUD patients from 2017 to 2021, focused on urine drug specimens provided for testing to Millennium Health, a third-party laboratory. Specimens were analyzed using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Generalized estimating equations (GEE) were used to estimate the average trends in positivity during time in treatment.

SETTING

Specimens were obtained from clinics in 10 US states that provided at least 300 unique patients during the study period (Alaska, Arizona, Florida, Illinois, Kentucky, Minnesota, New Mexico, Ohio, Virginia and Washington).

PARTICIPANTS

Patients with opioid use disorder receiving M-MOUD (n = 16 386).

MEASUREMENTS

Positivity rates for heroin, fentanyl, methamphetamine and cocaine.

FINDINGS

From 2017 to 2021, yearly crude positivity rates for first collected specimens increased for fentanyl (13.1%-53.0%, P < 0.001), methamphetamine (10.6%-27.2%, P < 0.001) and cocaine (13.8%-19.5%, P < 0.001); for heroin positivity did not significantly change (6.9%-6.5%, P = 0.74). In regression models estimating patient trajectories from week 1 to week 52, marginal fentanyl positivity declined from 21.8% to 17.1% (incidence rate ratio [IRR] = 0.78, P < 0.001) and heroin positivity declined from 8.4% to 4.3% (IRR = 0.51, P < 0.001), but positivity for methamphetamine and cocaine did not significantly change, remaining at an average of 17.7% (IRR = 0.98, P = 0.53) and 9.2% (IRR = 0.96, P = 0.36), respectively.

CONCLUSIONS

Between 2017 and 2021, United States patients presenting to opioid treatment programs increasingly tested positive for fentanyl, methamphetamine and cocaine. Methadone medication treatment for opioid use disorder appears to remain an effective intervention for reducing illicit opioid use.

Opioid agonist therapy switching among individuals with prescription-type opioid use disorder: Secondary analysis of a pragmatic randomized trial

BACKGROUND

Engagement and retention in opioid agonist therapy (OAT) remains a challenge. This study evaluated the impact of initial randomized OAT allocation on subsequent switching among people with prescription-type opioid use disorder (POUD).

METHODS

Secondary analysis of a 24-week Canadian multicenter, pragmatic, randomized trial conducted between 2017 and 2020 comparing flexible take-home buprenorphine/naloxone versus supervised methadone models of care for POUD. We used Cox Proportional Hazards modeling to assess for impact of treatment assignment on time to OAT switching, adjusting for important confounders. For clinical correlates, we analyzed data from baseline questionnaires on demographic, substance use, and health factors as well as urine drug screen.

RESULTS

Of 272 randomized participants, 210 initiated OAT within 14 days per trial protocol, of whom 103 participants were randomized to buprenorphine/naloxone and 107 to methadone. Within 24-week follow-up, 41 (20.5%) of all participants switched OAT with 25 (24.3%, median 27 days, 88.4 per 100 person-years) and 16 participants (15.0%, median 53.5 days, 46.1 per 100 person-years) switching from buprenorphine/naloxone and methadone arms, respectively. In adjusted analysis, allocation to buprenorphine/naloxone was associated with significantly higher risk of switching (aHR = 2.31, 95% CI 1.22 - 4.38).

CONCLUSIONS

OAT switching was common in this sample of individuals with POUD, with individuals randomly allocated to buprenorphine/naloxone being more than twice as likely to switch versus methadone. This may reflect a stepped care approach in OUD management. More research is needed to evaluate overall retention and outcomes with the different observed risks of switching between methadone and buprenorphine/naloxone.

Qualitative Exploration of Emergency Department Care Experiences Among People With Opioid Use Disorder

STUDY OBJECTIVE

We described the experiences and preferences of people with opioid use disorder who access emergency department (ED) services regarding ED care and ED-based interventions.

METHODS

Between June and September 2020, we conducted phone or in-person semistructured qualitative interviews with patients recently discharged from 2 urban EDs in Vancouver, BC, Canada, to explore experiences and preferences of ED care and ED-based opioid use disorder interventions. We recruited participants from a cohort of adults with opioid use disorder who were participating in an ED-initiated outreach program. We transcribed audio recordings verbatim. We iteratively developed a thematic coding structure, with interim analyses to assess for thematic saturation. Two team members with lived experience of opioid use provided feedback on content, wording, and analysis throughout the study.

RESULTS

We interviewed 19 participants. Participants felt discriminated against for their drug use, which led to poorer perceived health care and downstream ED avoidance. Participants desired to be treated like ED patients who do not use drugs and to be more involved in their ED care. Participants nevertheless felt comfortable discussing their substance use with ED staff and valued continuous ED operating hours. Regarding opioid use disorder treatment, participants supported ED-based buprenorphine/naloxone programs but also suggested additional options (eg, different initiation regimens and settings and other opioid agonist therapies) to facilitate further treatment uptake.

CONCLUSION

Based on participant experiences, we recommend addressing potentially stigmatizing practices, increasing patient involvement in their care during ED visits, and increasing access to various opioid use disorder-related treatments and community support.

A Generation Ready for Change: Preparing for the Deregulation of Medications for Opioid Use Disorder in Undergraduate Medical Education

The U.S. Department of Health and Human Services recently released updated guidance that allows providers under standard licensure to treat 30 or fewer patients with buprenorphine, a partial opioid agonist shown to be safe and effective as an office-based treatment for opioid use disorder (OUD). Previously, physicians and advanced practice providers needed to complete specialized training and certification under the Drug Addiction Treatment Act (DATA) of 2000 before prescribing medications for OUD (MOUD). This deregulatory action comes as rates of opioid-involved overdose have accelerated during the COVID-19 pandemic. Given the limited success of stepwise efforts to legislate for expanded access to MOUD, providers, professional associations, and other advocates have called for the elimination of the DATA requirements for all practitioners. An understanding of the statutory and regulatory history of MOUD may prove critical as legislative and policy actions continue to reshape clinical practice. Incorporating MOUD training as a standard in undergraduate medical education represents a unique opportunity for the medical community to prepare trainees for future deregulation of MOUD. Indeed, medical schools already offering or requiring MOUD training have demonstrated success in improving MOUD knowledge, skills, and attitudes among medical students and graduates. Existing virtual and hybrid training tools designed to meet DATA standards represent an accessible means to ensure critical learning for future generations of physicians uniquely ready and willing and to provide quality, evidence-based care to patients with OUD.

To Prescribe or Not to Prescribe?: Barriers and Motivators for Progressing Along Each Stage of the Buprenorphine Training and Prescribing Path

This study aimed to identify the strongest barriers and motivators associated with each step toward buprenorphine prescribing (1. obtaining a waiver, 2. beginning to prescribe, and 3. prescribing to more people) among a sample of Missouri-based medical professionals (N = 130). Item weights (number of endorsements times mean rank of the item's importance) were calculated based on their responses. Across groups, lack of access to psychosocial support services, need for higher levels of care, and clinical complexity were strong barriers. Among non-prescribers (n = 57, 46.3%), administrative burden, potential of becoming an addiction clinic, and concern about misuse and diversion were most heavily weighted. Among prescribers (n = 66, 53.7%), patients' inability to afford medications was a barrier across phases. Prominent motivators among all groups were the effectiveness of buprenorphine, improvement in other health outcomes, and a personal interest in treating addiction. Only prescribers reported the presence of institutional support and mentors as significant motivators.

Iteration is not solving the opioid crisis, it's time for transformation

Opioid use disorder (OUD) produces exceedingly high rates of morbidity and mortality in the United States and throughout the world. Almost 90% of persons qualifying for treatment do not enter treatment and 72% of those who initiate treatment leave within 60 days. This Perspective posits that over the past decade our OUD treatment system has produced only small iterative gains in treatment access because, in part, it is founded in a series of top-down regulatory policies dating back more than 100 years. These policies prioritized restricting persons with OUD from having access to opioid agonists over empirical discovery of treatment best practice. It further suggests that for persons who are not already responding positively to our existing treatments, we may need to fundamentally transform care to enact true, meaningful change. Four potential considerations are outlined: expanding beyond long-acting opioids for treatment, embracing safe use as a viable therapeutic target, ending closed medication distribution systems, and partnering with our patients. The overarching aim of this discussion is to motivate broader thinking about new solutions for the patients for whom the existing strategies are not working and who may benefit from more transformative approaches. Though efforts to-date to expand existing treatment systems and find new ways to promote existing MOUDs have been important, these efforts have represented iterative changes. For us to meet our goal of substantially reducing opioid-related harms, it may be time to consider strategies that represent true transformation.

METHADONE INITIATION IN THE EMERGENCY DEPARTMENT FOR OPIOID USE DISORDER: A CASE SERIES

BACKGROUND

In an era of fentanyl and continually rising rates of opioid overdose deaths, increasing access to evidence-based treatment for opioid use disorder (OUD) should be prioritized. Emergency department (ED) buprenorphine initiation for patients with OUD is considered best-practice. Methadone, though also evidence-based and effective, is under-utilized due to strict federal regulation, significant stigma, and lack of physician training. We describe the novel utilization of CFR Title 21 1306.07 (b), also known as the "72-hour rule," to initiate methadone for OUD in the ED.

CASE SERIES

We describe the cases of 3 patients with a history of OUD who were initiated on methadone for OUD in the ED, linked to an opioid treatment program, and attended an intake appointment. Why Should an Emergency Physician Be Aware of This? The ED can be a crucial point of intervention for vulnerable patients with OUD who may not interact with the health care system in other settings. Methadone and buprenorphine are both first-line options for medication for OUD, and methadone may be preferred in patients who have been unsuccessful with buprenorphine in the past or those at higher risk of treatment dropout. Patients may also prefer methadone to buprenorphine based on previous experience or understanding of the medications. ED physicians may utilize the "72-hour rule" to administer and initiate methadone for up to 3 consecutive days while arranging referral to treatment. EDs can develop methadone initiation and bridge programs utilizing similar strategies to those that have been described in developing buprenorphine programs.

Perspectives Regarding Medications for Opioid Use Disorder Among Individuals with Mental Illness

Most people with co-occurring opioid use disorder (OUD) and mental illness do not receive effective medications for treating OUD. To investigate perspectives of adults in a publicly-funded mental health system regarding medications for OUD (MOUD), we conducted semi-structured telephone interviews with 13 adults with OUD (current or previous diagnosis) receiving mental health treatment. Themes that emerged included: perceiving or using MOUDs as a substitute for opioids or a temporary solution to prevent withdrawal symptoms; negative perceptions about methadone/methadone clinics; and viewing MOUD use as "cheating". Readiness to quit was important for patients to consider MOUDs. All participants were receptive to discussing MOUDs with their mental health providers and welcomed the convenience of receiving care for their mental health and OUD at the same location. In conclusion, clients at publicly-funded mental health clinics support MOUD treatment, signaling a need to expand access and build awareness of MOUDs in these settings.

Should I Stay or Should I Go? A Qualitative Exploration of Stigma and Other Factors Influencing Opioid Agonist Treatment Journeys

(1) The harm-reduction benefits of opioid agonist treatment (OAT) are well-established; however, the UK government's emphasis on "recovery" may be contributing to a high proportion of people leaving treatment and low retention rates. We wanted to develop a rich and nuanced understanding of the factors that might influence the treatment journeys of people who use OAT. (2) We explored factors at each level of the socioecological system and considered the ways these interact to influence treatment journeys in OAT. We carried out semi-structured interviews with people who use OAT (n = 12) and service providers (n = 13) and analysed data using reflexive thematic analysis. (3) We developed three themes representing participant perceptions of treatment journeys in OAT. These were: (1) The System is Broken; (2) Power Struggles; and (3) Filling the Void. (4) Conclusions: The data suggest that prioritisation of treatment retention is important to preserve the harm-reduction benefits of OAT. Stigma is a systemic issue which presents multiple barriers to people who use OAT living fulfilling lives. There is an urgent need to develop targeted interventions to address stigma towards people who use OAT.

"I'm Clean and Sober, But Not Necessarily Free": Perceptions of Buprenorphine Among Patients in Long-Term Treatment

BACKGROUND

Patients receiving buprenorphine for the treatment of opioid use disorder (OUD) experience a roughly 50% reduction in mortality risk relative to those not receiving medication. Longer periods of treatment are also associated with improved clinical outcomes. Despite this, patients often express desires to discontinue treatment and some view taper as treatment success. Little is known about the beliefs and medication perspectives of patients engaged in long-term buprenorphine treatment that may underlie motivations to discontinue.

METHODS

This study was conducted at the VA Portland Health Care System (2019-2020). Qualitative interviews were conducted with participants prescribed buprenorphine for ≥2 years. Coding and analysis were guided by directed qualitative content analysis.

RESULTS

Fourteen patients engaged in office-based buprenorphine treatment completed interviews. While patients expressed strong enthusiasm for buprenorphine as a medication, the majority expressed the desire to discontinue, including patients actively tapering. Motivations to discontinue fell into 4 categories. First, patients were troubled by perceived side effects of the medication, including effects on sleep, emotion, and memory. Second, patients expressed unhappiness with being "dependent" on buprenorphine, framed in opposition to personal strength/independence. Third, patients expressed stigmatized beliefs about buprenorphine, describing it as "illicit," and associated with past drug use. Finally, patients expressed fears about buprenorphine unknowns, including potential long-term health effects and interactions with medications required for surgery.

CONCLUSIONS

Despite recognizing benefits, many patients engaged in long-term buprenorphine treatment express a desire to discontinue. Findings from this study may help clinicians anticipate patient concerns and can be used to inform shared decision-making conversations regarding buprenorphine treatment duration.

Anticipated Barriers to Sustained Engagement in Treatment With Medications for Opioid Use Disorder After Release From Incarceration

BACKGROUND

Although the burden of opioid use disorder is disproportionately high among persons who are incarcerated, medications for opioid use disorder are often unavailable in correctional settings. The Rhode Island Department of Corrections provides all 3 classes of medications for opioid use disorder to clinically eligible persons who are incarcerated. Despite a decrease in fatal overdoses among persons with recent criminal legal system involvement since the program's implementation, barriers to continued engagement in treatment after release from incarceration still exist.

METHODS

We conducted 40 semistructured, qualitative interviews with people who were incarcerated and enrolled in the comprehensive medications for opioid use disorder program at the Rhode Island Department of Corrections. Analysis applied a general, inductive approach using NVivo 12.

RESULTS

Participants discussed barriers to treatment engagement before incarceration, as well as anticipated barriers to medications to treat opioid use disorder continuation after release from incarceration. Structural factors including housing, health insurance, transportation, and the treatment program structure, as well as social factors such as social support networks were perceived to influence retention in medications to treat opioid use disorder post-release.

CONCLUSION

Our findings suggest that people with opioid use disorder who are incarcerated encounter unique challenges upon community reentry. Addressing structural factors that pose barriers to post-release engagement is essential to sustaining retention. We recommend utilization of peer recovery specialists to alleviate some of the stress of navigating the structural barriers identified by participants.

When a pandemic and epidemic collide: Lessons learned about how system barriers can interrupt implementation of addiction research

Background

Telehealth technologies are now featured more prominently in addiction treatment services than prior to the COVID-19 pandemic, but system barriers should be carefully considered for the successful implementation of innovative remote solutions for medication management and recovery coaching support for people with opioid use disorder (OUD).

Method

The Centers for Disease Control and Prevention funded a telehealth trial prior to the COVID-19 pandemic with a multi-institution team who attempted to implement an innovative protocol during the height of the pandemic in 2020 in Tampa, Florida. The study evaluated the effectiveness of a mobile device application, called MySafeRx, which integrated remote motivational recovery coaching with daily supervised dosing from secure pill dispensers via videoconference, on medication adherence during buprenorphine treatment. This paper provides a participant case example followed by a reflective evaluation of how the pandemic amplified both an existing research-to-practice gap and clinical system barriers during the implementation of telehealth clinical research intervention for patients with OUD.

Findings

Implementation challenges arose from academic institutional requirements, boundaries and role identity, clinical staff burnout and lack of buy-in, rigid clinical protocols, and limited clinical resources, which hampered recruitment and intervention engagement.

Conclusions

As the urgency for feasible and effective telehealth solutions continues to rise in response to the growing numbers of opioid-related deaths, the scientific community may use these lessons learned to re-envision the relationship between intervention implementation and the role of clinical research toward mitigating the opioid overdose epidemic.

Awareness, perception and utilization of a mobile health clinic by people who use drugs

INTRODUCTION

People who use drugs (PWUD) face a multitude of barriers to accessing healthcare and other services. Mobile health clinics (MHC) are an innovative, cost-effective health care delivery approach that increases healthcare access to vulnerable populations and medically underserved areas. There is limited understanding, however, of how PWUD perceive and experience MHCs.

METHODS

Semi-structured interviews were conducted with 31 PWUD - 16 who had received care (clients) on an MHC (The Spot) and 15 who had not (non-clients) - to explore their perceptions and utilization of an MHC partnered with a mobile syringe services program in Baltimore, Maryland. Data analysis of the text was conducted using an iterative thematic constant comparison process informed by grounded theory.

RESULTS

Clients and non-clients, once aware of the MHC, had positive perceptions of The Spot and its benefits for their individual health as well as for the wellbeing of their community. These sentiments among clients were largely driven by access to low-barrier buprenorphine and service delivery without stigma around drug use. However, lack of general awareness of the spot and specific service offering were barriers to its use among non-clients.

DISCUSSION

MHCs provide an important opportunity to engage PWUD in healthcare and to expand buprenorphine use; however, even with accessibility near where PWUD access injection equipment, barriers to its use remain. Peer dissemination may be able to facilitate program information sharing and recruitment.KEY MESSAGESPeople who use drugs perceive a mobile health clinic in their neighbourhood as a benefit to their communities and themselves by improving access to healthcare services, providing access to low-threshold buprenorphine dispensation, and offering services without drug use stigma.People who use drugs learned about a mobile health clinic in their neighbourhood largely through word-of-mouth. As a result, people received limited information about the mobile health clinic services creating a barrier to its use.

Rapid Overlap Initiation Protocol Using Low Dose Buprenorphine for Opioid Use Disorder Treatment in an Outpatient Setting: A Case Series

OBJECTIVES

Fear and risk of precipitated withdrawal are barriers for initiating buprenorphine in individuals with opioid use disorder, particularly among those using fentanyl. A buprenorphine rapid overlap initiation (ROI) protocol (also knownas "rapidmicro-dosing") utilizing small, escalating doses of buprenorphine can overcome this barrier, reaching therapeutic doses in 3 to 4 days. We sought to demonstrate the feasibility of implementing a buprenorphine ROI protocol for buprenorphine initiation in the outpatient setting.

METHODS

We conducted a retrospective chart review of patients prescribed an outpatient ROI protocol at the Office-based Buprenorphine Induction Clinic from October to December 2020. The ROI protocol utilizes divided doses of sublingual buprenorphine tablets and blister packaging for easier dosing. Patients were not required to stop other opioid use and were advised to follow up on day 4 of initiation.

RESULTS

Twelve patients were included, of whom eleven (92%) were using fentanyl at intake. Eleven patients picked up their prescription. Seven patients returned for follow-up (58%), and all 7 completed the ROI protocol. One patient reported any withdrawal symptoms, which were mild. At 30 days, 7 patients (58%) were retained in care, and 5 (42%) were still receiving buprenorphine treatment, 4 (33%) of whom had been abstinent from nonprescribed opioid use for ≥2 weeks.

CONCLUSIONS

The ROI protocol was successful in initiating buprenorphine treatment for patients in our outpatient clinic, many of whom were using fentanyl. The ROI protocol may offer a safe alternative to traditional buprenorphine initiation and warrants further study.

Duration of use and outcomes among people with opioid use disorder initiating methadone and buprenorphine in Ontario: a population-based propensity-score matched cohort study

AIMS

To characterize comparative risks and benefits of methadone versus buprenorphine/naloxone in a contemporary cohort where the unregulated drug supply is dominated by fentanyl.

DESIGN, SETTING AND PARTICIPANTS

Population-based propensity-score matched cohort study conducted in Ontario, Canada among people aged 18+ initiating opioid agonist therapy (OAT) for an opioid use disorder between October 2016 and December 2018 (n = 18 880).

INTERVENTION

Initiation of methadone versus buprenorphine/naloxone.

MEASUREMENTS

The primary outcome was opioid overdose (fatal and non-fatal) while on treatment, with secondary outcomes including opioid overdose (first 30 days of treatment), treatment discontinuation, health-care interactions related to treatment of opioid use disorder, receiving a weekly supply of take-home doses and opioid overdose within 30 days of treatment discontinuation. Outcomes were assessed over 1 year.

FINDINGS

Overall, 7517 people initiating buprenorphine were matched to an equal number of methadone-treated individuals. Risk of opioid overdose while on treatment [hazard ratio (HR) = 0.50; 95% confidence interval (CI) = 0.37-0.68] or within the first 30 days of treatment (HR = 0.51, 95% CI = 0.31-0.85) was lower among buprenorphine recipients compared to methadone recipients. In secondary analyses, people initiating buprenorphine had a higher risk of treatment discontinuation within the first year (median time to discontinuation 104 versus 265 days, HR = 1.43, 95% CI = 1.37-1.49), had lower rates of health-care interactions for OUD (186.4 versus 254.3 per person-year; rate ratio = 0.73; 95% CI = 0.72-0.75), and a higher rate of receiving weekly take-home doses (HR = 2.33; 95% CI = 2.20-2.46). Overdose rates in the period following OAT discontinuation were higher than those observed while on treatment, but did not differ significantly by OAT type.

CONCLUSIONS

Although treatment retention is higher among methadone recipients, overdose risk is also elevated compared to buprenorphine recipients. These findings demonstrate the benefits of any OAT on avoidance of overdose, particularly following treatment discontinuation and with the increasingly unpredictable drug supply in North America.

Impact of the COVID-19 pandemic on the prevalence of opioid agonist therapy discontinuation in Ontario, Canada: A population-based time series analysis

BACKGROUND

We assessed the impact of COVID-19, which includes the declaration of a state of emergency and subsequent release of pandemic-specific OAT guidance (March 17, 2020 to March 23, 2020) on the prevalence of OAT discontinuation.

METHODS

We conducted a population-based time series analysis using interventional autoregressive integrated moving average models among Ontario residents who were stable (>60 days of continuous use) and not yet stable on OAT. Specifically, we examined whether COVID-19 impacted the weekly percentage of individuals who discontinued OAT, overall and stratified by treatment type (methadone vs. buprenorphine/naloxone). Additionally, we compared demographic characteristics and patient outcomes among people stable on OAT who discontinued treatment during (March 17, 2020 to November 30, 2020) and prior (July 3, 2019 to March 16, 2020) to the pandemic.

RESULTS

The weekly prevalence of OAT discontinuation across the study period ranged between 0.6% and 1.1%, among those stable on treatment compared to 7.3% and 16.6%, among those not stable on treatment. Following COVID-19, there was no significant change in the percentage of Ontarians who discontinued OAT, regardless of whether they were stabilized on treatment. Among those stable on OAT, a similar proportion of patients restarted therapy and experienced opioid-related harm following an OAT discontinuation. However, mortality following OAT discontinuation must be noted, as approximately 1.4% and 0.8% of people who discontinued methadone and buprenorphine/naloxone respectively, died within 30 days of discontinuation.

CONCLUSIONS

Trends in the prevalence of OAT discontinuation did not significantly change during the first eight months of the COVID-19 pandemic.

Treatment Experiences Among People Who Use Opioids: A Social Ecological Approach

The prevalence of opioid use disorder (OUD) and surge in overdose deaths remain key public health concerns. Despite evidence supporting the efficaciousness of medications for opioid use disorder, most people with OUD do not receive treatment. In this qualitative study, semi-structured interviews were conducted with 35 adults in a northeastern city to learn about their experiences with substance use treatment. Qualitative data were analyzed using an inductive thematic content analysis approach, and a social ecological model was applied to examine contextual factors affecting participants' experiences accessing and engaging in treatment. While we organized our findings following the individual, interpersonal, community, and society levels of the socio-ecological model, we also observed overlap and interconnectedness between and across these levels. Our findings suggest that retention in treatment often depends upon personal motivation, treatment availability, the match of the treatment modality to an individual's needs, and social support. A person-centered approach is needed to promote individualized care and tailor treatment components to the patient's needs.

County-level sociodemographic differences in availability of two medications for opioid use disorder: United States, 2019

BACKGROUND

Differences in availability of medications for opioid use disorder (MOUD) buprenorphine and methadone exist. Factors that may influence such differences in availability include sociodemographic characteristics but research in this area is limited. We explore the association between county-level sociodemographic factors and MOUD treatment availability.

METHODS

County-level Drug Enforcement Administration (DEA) data were used to determine the presence or absence of buprenorphine treatment or opioid treatment programs (OTPs) and the level of availability of these types of treatment in a county. Hurdle models were used to examine the associations of our covariates with any MOUD treatment availability and level of available treatment.

RESULTS

The odds of a county having OTP availability were higher for counties with higher percentages of non-Hispanic Black and Hispanic populations and higher drug overdose death rates. Counties with higher percentages of persons in poverty and drug overdose death rates had higher odds of maximum potential buprenorphine treatment capacity, while counties with high percentages of persons without health insurance, with disability, and rural counties had lower odds.

CONCLUSIONS

There are significant differences in the county-level availability of OTPs and buprenorphine treatment. Our findings expand on prior studies illustrating that barriers to accessing treatment persist and are not evenly distributed among sociodemographic groups, further study is needed to examine if barriers of availability translate to barriers in receiving treatment. Given the escalating overdose crisis in the U.S., expanding equitable availability of MOUD is critical. Informed strategies are needed to reach areas and populations in greatest need.

Geographic disparities in access to Medication for Opioid Use Disorder across US census tracts based on treatment utilization behavior

Drug overdose is the leading cause of accidental death in the U.S. with deaths from opioid overdose occurring at a higher rate in rural areas. The gaps in the provision of healthcare services have been exacerbated by the opioid crisis leaving vulnerable populations without access to preventative care and education, harm reduction, both chronic and acute treatment of the symptoms of opioid use disorder (OUD), and long-term psychological support for those with OUD and their families. There has been a call in the literature -and a federal mandate-for increased access to opioid treatment facilities, but to date this access has not been operationalized using best practices in geography. Medication for Opioid Use Disorder (MOUD) with FDA-approved methadone or buprenorphine has been shown to increase treatment retention, reduce opioid use and associated health and societal harms, and reduce opioid related overdose, and as such is considered the most effective treatment for OUD. The objective of this study is to examine U.S. adults' spatial access to MOUD - specifically locations of certified Opioid Treatment Programs (OTPs) and DATA-waived Buprenorphine providers. A gravity-based variant of the enhanced two-step floating catchment area model is employed, where friction of distance is based on previously published willingness to travel distances for patients visiting OTPs, to assess how opioid agonist treatment accessibility varies across the nation. Findings suggest that there are extensive 'treatment deserts' where there is little to no physical access to MOUD, especially in rural areas. The significance of this work lies in the incorporation of treatment utilization behavior in the access metric, and the continued confirmation of gaps in access to OUD services despite federal efforts to improve accessibility.

Measuring treatment attrition at various stages of engagement in Opioid Agonist Treatment in Ontario Canada using a cascade of care framework

Background

The cascade of care framework is an effective way to measure attrition at various stages of engagement in Opioid Agonist Treatment (OAT). The primary objective of the study was to describe the cascade of care for patients who have accessed OAT from a network of specialized addiction clinics in Ontario, Canada. The secondary objectives were to evaluate correlates associated with retention in OAT at various stages and the impact of patients’ location of the residence on retention in OAT.

Design

A multi-clinic retrospective cohort study was conducted using electronic medical record (EMR) data from the largest network of OAT clinics in Canada (70 clinics) from 2014 to 2020. Study participants included all patients who received OAT from the network of clinics during the study period.

Measurements

In this study, four stages of the cascade of care framework were operationalized to identify treatment engagement patterns, including patients retained within 90 days, 90 to 365 days, one to 2 years, and more than 2 years. Correlates associated with OAT retention for 90 days, 90 to 365 days, 1 to 2 years, and more than 2 years were also evaluated and compared across rural and urban areas in northern and southern Ontario.

Results

A total of 32,487 patients were included in the study. Compared to patients who were retained in OAT for 90 days, patients who were retained for 90 to 365 days, 1 to 2 years, or more than 2 years were more likely to have a higher number of treatment attempts, a higher number of average monthly urine drug screening and a lower proportion of positive urine drug screening results for other drug use.

Conclusion

Distinct sociodemographic and clinical factors are likely to influence treatment retention at various stages of engagement along the OAT continuum. Research is required to determine if tailored strategies specific to people at different stages of retention have the potential to improve outcomes of OAT.

Structural violence and the need for compassionate use of methadone in Mexico

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.

Opioid agonist treatment (OAT) experiences and release plans among federally incarcerated individuals with opioid use disorder (OUD) in Ontario, Canada: a mixed-methods study

Background

Incarcerated populations experience an elevated prevalence of opioid use disorder (OUD). Federal correctional institutions in Canada have increasingly treated OUD among correctional populations via opioid agonist treatment (OAT) – an evidence based pharmacotherapy that works to reduce drug use and related health harms. However, there is limited evidence regarding incarcerated individuals’ experiences with institutional-based OAT, as well potential OAT-related community release prospects. This information is important for optimal treatment retention and improved health. To address this knowledge gap, we conducted a longitudinal follow-up study examining OAT-related experiences among federally incarcerated individuals before and after community release. This article focuses on the baseline (pre-release) data.

Methods

This mixed-methods study examined OAT-related experiences and release prospects among n = 46 individuals scheduled for community release, recruited from seven federal prisons located in Ontario, Canada. Participants underwent a comprehensive interviewer-administered on-site assessment, including quantitative and qualitative items. Assessment data was furthermore linked to administrative correctional data. Data were analyzed using thematic qualitative and descriptive quantitative approaches.

Results

Participants had complex histories with opioid use including related negative health outcomes. Experiences with institutional OAT were divergent and provision was not standardized; those with OAT engagement pre-admission did not experience many challenges, whereas those initiating OAT during incarceration experienced barriers such as treatment waitlists and adverse process experiences. Most participants expressed a preference for buprenorphine-naloxone over methadone, but described difficulties accessing it. Participants were keen to transition into community-based treatment, yet envisaged prospective barriers and facilitators concerning successful reintegration and treatment continuity.

Conclusions

Major barriers towards the current administration of OAT in federal correctional systems in Canada exist, including extensive waitlists, non-standardized practices, and challenges accessing preferred OAT formulations; this contributes to sub-optimal treatment. Eliminating waitlists, standardizing OAT provision, providing additional OAT options, and more comprehensive release planning may be essential for treatment retention and positive outcomes.

Emergency Department-initiated Buprenorphine and Referral to Follow-up Addiction Care: A Program Description

INTRODUCTION

Emergency department (ED) initiated opioid use disorder (OUD) care is effective; however, real-world predictors of patient engagement are lacking.

OBJECTIVE

This program evaluation examined predictors of ED-based OUD treatment and subsequent engagement.

METHOD

Program evaluation in Boston, MA. Adult patients who met criteria for OUD during an ED visit in 2019 were included. Patients were included if a diagnosis of OUD or opioid-related overdose was associated with the ED visit or if they met previously validated criteria for OUD within the previous 12 months. We assessed predictors of ED-OUD treatment receipt and subsequent engagement, using Healthcare Effectiveness Data and Information Set definition of initial encounter within 14 days of discharge and either 2 subsequent encounters or a subsequent buprenorphine prescription within 34 days of the initial encounter. We used generalized estimating equations for panel data.

RESULTS

During 2019, 1946 patients met criteria for OUD. Referrals to Bridge Clinic were made for 207 (11%), buprenorphine initiated for 106 (5%), and home induction buprenorphine kits given to 56 (3%). Following ED discharge, 237 patients (12%) had a visit within 14 days, 122 (6%) had ≥2 additional visits, and 207 (11%) received a subsequent buprenorphine prescription. Young, White, male patients were most likely to receive ED-OUD care. Patients who received ED-OUD care were more likely to have subsequent treatment engagement (adjusted rate ratio: 2.30, 95% confidence intervals: 1.62-3.27). Referrals were made less often than predicted for Black (-49%) or Hispanic/Latinx (-25%) patients.

CONCLUSIONS

Initiating treatment for OUD in the ED was associated with increased engagement in outpatient addiction care.

Association Between Increased Dispensing of Opioid Agonist Therapy Take-Home Doses and Opioid Overdose and Treatment Interruption and Discontinuation

IMPORTANCE

During the COVID-19 pandemic, modified guidance for opioid agonist therapy (OAT) allowed prescribers to increase the number of take-home doses to promote treatment retention. Whether this was associated with an increased risk of overdose is unclear.

OBJECTIVE

To evaluate whether increased take-home doses of OAT early in the COVID-19 pandemic was associated with treatment retention and opioid-related harm.

DESIGN, SETTING, AND PARTICIPANTS

A retrospective propensity-weighted cohort study of 21 297 people actively receiving OAT on March 21, 2020, in Ontario, Canada. Changes in OAT take-home dose frequency were assessed between March 22, 2020, and April 21, 2020, and individuals were observed for up to 180 days to assess outcomes (last date of follow-up, October 18, 2020).

EXPOSURES

Exposure was defined as extended take-home doses in the first month of the pandemic within each of 4 cohorts based on OAT type and baseline take-home dose frequency (daily dispensed methadone, 5-6 take-home doses of methadone, daily dispensed buprenorphine/naloxone, and 5-6 take-home doses of buprenorphine/naloxone).

MAIN OUTCOMES AND MEASURES

Primary outcomes were opioid overdose, interruption in OAT, and OAT discontinuation.

RESULTS

Among 16 862 methadone and 4435 buprenorphine/naloxone recipients, the median age ranged between 38 and 42 years, and 29.1% to 38.2% were women. Among individuals receiving daily dispensed methadone (n = 5852), initiation of take-home doses was significantly associated with lower risks of opioid overdose (6.9% vs 9.5%/person-year; weighted hazard ratio [HR], 0.73 [95% CI, 0.56-0.96]), treatment discontinuation (51.0% vs 63.6%/person-year; weighted HR, 0.80 [95% CI, 0.72-0.90]), and treatment interruption (19.0% vs 23.9%/person-year; weighted HR, 0.80 [95% CI, 0.67-0.95]) compared with no change in take-home doses. Among individuals receiving daily dispensed buprenorphine/naloxone (n = 662), there was no significant difference in any outcomes between exposure groups. Among individuals receiving weekly dispensed OAT (n = 11 010 for methadone; n = 3773 for buprenorphine/naloxone), extended take-home methadone doses were significantly associated with lower risks of OAT discontinuation (14.1% vs 19.6%/person-year; weighted HR, 0.72 [95% CI, 0.62-0.84]) and interruption in therapy (5.1% vs 7.4%/person-year; weighted HR, 0.69 [95% CI, 0.53-0.90]), and extended take-home doses of buprenorphine/naloxone were significantly associated with lower risk of interruption in therapy (9.5% vs 12.9%/person-year; weighted HR, 0.74 [95% CI, 0.56-0.99]) compared with no change in take-home doses. Other primary outcomes were not significantly different between groups.

CONCLUSIONS AND RELEVANCE

In Ontario, Canada, during the COVID-19 pandemic, dispensing of increased take-home doses of opioid agonist therapy was significantly associated with lower rates of treatment interruption and discontinuation among some subsets of patients receiving opioid agonist therapy, and there were no statistically significant increases in opioid-related overdoses over 6 months of follow-up. These findings may be susceptible to residual confounding and should be interpreted cautiously.

"I wanted something that was more flexible": A qualitative study of patient preferences on choosing buprenorphine over methadone in a large, safety-net hospital opioid treatment program

Background: Buprenorphine availability for the treatment of opioid use disorders (OUD) has expanded in the United States. Programs that previously offered only methadone treatment to patients with OUD now offer an equal choice between buprenorphine and methadone at the same location, yet little is known about patient preferences for buprenorphine over methadone in these settings. We sought to understand the decision-making factors and motivations underlying why patients opt for buprenorphine over methadone for the treatment of OUD when both are offered in a safety-net hospital-based opioid treatment program (OTP). Methods: We conducted semi-structured, qualitative interviews with patients receiving buprenorphine, in which we asked about substance use and treatment history, reasons for choosing buprenorphine, advantages, and disadvantages of choosing buprenorphine, and what they would like to change in their treatment experience. Results: Participants had varied exposure to buprenorphine prior to their current treatment, ranging from none to years of experience in multiple settings. Increased flexibility with take-home doses was a widespread motivation for choosing buprenorphine over methadone. Participants described decreased sedation and greater effectiveness in preventing opioid use compared to methadone as advantages during their treatment with buprenorphine. Difficulty with the transition to buprenorphine was a noteworthy challenge for many. Conclusions: Overall, patients maintained on buprenorphine at an urban safety-net hospital OTP viewed their treatment favorably compared to methadone. Increased autonomy in light of federal regulation differences and an improved physical profile were significant decision-making factors, although the number of patients choosing buprenorphine at the OTP remained low. Targeted patient education about induction and focus on improving structural barriers such as dosing efficiency may enhance patient experiences.

Increasing Short- and Long-Term Buprenorphine Treatment Capacity: Providing Waiver Training for Medical Students

In the face of an ongoing opioid crisis in the United States, persistent treatment gaps exist for vulnerable populations. Among the 3 Food and Drug Administration-approved medications used to treat opioid use disorder, many patients prefer buprenorphine. But physicians are currently required to register with the Drug Enforcement Administration and complete 8 hours of qualifying training before they can receive a waiver to prescribe buprenorphine to their patients. In this article, the authors summarize the evolution of buprenorphine waiver training in undergraduate medical education and outline 2 potential paths to increase buprenorphine treatment capacity going forward: the curriculum change approach and the training module approach. As part of the 2018 Substance Use-Disorder Prevention that Promotes Opioid Recovery and Treatment for Patients and Communities Act, the Substance Abuse and Mental Health Services Administration has provided funding for medical schools to adapt their curricula to meet waiver training requirements. To date, however, only one school has had its curriculum approved for this purpose. Additionally, recent political efforts have been directed at eliminating aspects of the waiver training requirement and creating a more direct path to integrating waiver qualification into undergraduate medical education (UME). Other medical schools have adopted a more pragmatic approach involving the integration of existing online, in-person, and hybrid waiver-qualifying training modules into the curricula, generally for fourth-year students. This training module approach can be more rapidly, broadly, and cost-effectively implemented than the curriculum change approach. It can also be easily integrated into the online medical curricula that schools developed in response to the COVID-19 pandemic. Ultimately both curricular changes and support for student completion of existing training modules should be pursued in concert, but focus should not be single-mindedly on the former at the expense of the latter.

A qualitative meta-synthesis of pregnant women's experiences of accessing and receiving treatment for opioid use disorder

ISSUES

Addressing opioid use disorder (OUD) among pregnant women is of growing importance, and substance use treatment positively impacts outcomes for mother and baby. Understanding substance use treatment experiences is important to improve access, and retention, and no review or synthesis of research addressing the treatment experiences of pregnant women exists.

APPROACH

Thus, a qualitative meta-synthesis was conducted, which investigated the psychological motivators and barriers of pregnant women with OUD trying to access treatment and their perceptions of treatment.

KEY FINDINGS

A total of 3844 articles were retrieved from the literature search. Nine articles met eligibility criteria, were appraised, then synthesised using a comparative thematic approach. Four themes: (i) Embodied Experiences; (ii) Institutional Pressures; (iii) Social Context; and (iv) Reconstructing Selves; indicate that women with OUD are motivated to engage in treatment to pursue the safety and custody of the unborn baby and to pursue and enact the changes necessary to claim 'normal' parenthood status. Pregnant women describe psychological and relational barriers to engaging in treatment, including anxieties about the baby's health, fears of authorities' involvement, stigma and experiencing relationships with treatment providers as constrictive or invalidating.

IMPLICATIONS

Identity theory's concepts of identity verification, closed environments and master status identities illuminate the findings. Implications include recognising the salience of bodily experiences, providing medication-assisted treatment support groups and promoting validating relationships in treatment using strengths-based approaches.

CONCLUSIONS

Pregnant women face unique psychological challenges in accessing and engaging in substance use treatment for OUD.

Rural opioid treatment program patient perspectives on take-home methadone policy changes during COVID-19: a qualitative thematic analysis

BACKGROUND

In the United States, methadone for opioid use disorder (OUD) is highly regulated. Federal agencies announced guidelines in March 2020 allowing for relaxation of take-home methadone dispensing at opioid treatment programs (OTPs) to improve treatment access and reduce COVID-19 transmission risk during the public health emergency. We explored patient perspectives at three OTPs serving rural communities on how take-home policy changes were received and implemented and how these changes impacted their addiction treatment and recovery.

METHODS

We completed semi-structured individual qualitative interviews in 2 phases: (1) August-October 2020 and (2) November 2020-January 2021 (total n = 46), anticipating possible policy changes as the pandemic progressed. We interviewed patients with OUD enrolled at 3 rural OTPs in Oregon. Participants received varying take-home methadone allowances following the COVID-19-related policy changes. All interviews were conducted via phone, audio-recorded, and transcribed. We conducted a thematic analysis, iteratively coding transcripts, and deductively and inductively generating codes.

RESULTS

The 46 participants included 50% women and 89% had Medicaid insurance. Three main themes emerged in the analysis, with no differences between study phases: (1) Adapting to changing OTP policies throughout the pandemic; (2) Recognizing the benefits, and occasional struggles, with increased take-home methadone dosing; and (3) Continuing policies and procedures post-pandemic. Participants described fears and anxieties around ongoing methadone access and safety concerns prior to OTP policy changes, but quickly adapted as protocols soon seemed "natural." The majority of participants acknowledged significant benefits to increased take-homes independent of reducing COVID-19 infection risk including feeling "more like a normal person," improved recovery support, reduced time traveling, and having more time with family and for work. Looking to a post-pandemic future, participants thought some COVID-19-related safety protocols should continue that would reduce risk of other infections, make OTP settings less stressful, and result in more individualized care.

CONCLUSIONS

As the pandemic progressed, study participants adapted to rapidly changing OTP policies. Participants noted many unanticipated benefits to increased take-home methadone and other COVID-19 protocols including strengthened self-efficacy and recovery and reduced interpersonal conflict, with limited evidence of diversion. Patient perspectives should inform future policies to better address the ongoing overdose epidemic.

Treatment options and shared decision-making in the treatment of opioid use disorder: A scoping review

BACKGROUND

Shared decision-making (SDM) is an approach to clinical decision-making that includes patients' values and preferences during health-related decisions. Previous research suggests that SDM may be beneficial in the treatment of substance use disorders; however, the impact of SDM in the treatment of opioid use disorder (OUD) remains unclear.

OBJECTIVES

To identify relevant peer-reviewed literature related to SDM in the treatment of adults with OUD, and to summarize the main findings according to patient outcomes.

METHODS

The research team conducted a scoping review. The team searched five electronic health databases from database inception until September 2019 using MeSH and keywords related to SDM. The team included only peer-reviewed studies where adults (≥18 years) with OUD were provided a choice and/or allowed input into their treatment plan. Two independent reviewers screened, extracted, and assessed the quality of included studies.

RESULTS

Fourteen studies (n = 1748 participants) met inclusion criteria, including seven randomized controlled trials, three non-randomized controlled trials, two observational studies, and one qualitative study. Treatment options included: patient regulated methadone dosing vs. fixed dosing (n = 4 studies), optional vs. mandatory counseling (n = 4 studies), home vs. office buprenorphine inductions (n = 2 studies), and inpatient vs. outpatient treatment (n = 1 study). None of the studies measured SDM with a validated instrument. Seven of 14 studies reported at least one improved patient outcome.

CONCLUSIONS

The review found few studies that explored whether providing treatment options and/or encouraging participation in decision-making are beneficial for adults with OUD. Preliminary evidence suggests that SDM may be promising for this population. However, the field needs more research on person-centered care and SDM.
