Comparing Reasons for Starting and Stopping Methadone, Buprenorphine, and Naltrexone Treatment Among a Sample of White Individuals With Opioid Use Disorder

Discontinuation of medication treatment for opioid use disorder after a successful course: The discontinuation phase of the CTN-0100 (RDD) trial

INTRODUCTION AND BACKGROUND

Buprenorphine, and extended-release naltrexone, are effective in decreasing opioid use, morbidity and mortality. The available evidence suggests that these medications should be used for long term treatment; however, patients often ask how long they need to be on medication, and whether it would be safe to discontinue. There are sparse data to guide us. The CTN-0100 trial will address this gap in our knowledge by studying participants who have decided to discontinue buprenorphine and extended-release naltrexone for OUD.

RESEARCH DESIGN AND METHODS

The trial is a multicenter, randomized, non-blinded study. Participants are stable adult volunteers, on sublingual buprenorphine, extended-release buprenorphine, or extended-release naltrexone, expressing an interest in discontinuing medication. Participants on buprenorphine must be stable for at least 1 year and participants on extended-release naltrexone must be stable for at least 6 months. Participants are engaged in the study for up to 96 weeks, including a flexible taper period, and are then transitioned to follow-up within the trial. All participants are randomly assigned to the study Medical Management (MM) or to MM plus Connections (CHESS health) digital smartphone application aimed at recovery and abstinence (MMD). Sublingual Buprenorphine participants are also randomized (2 × 2 design) to a taper using either sublingual or extended-release buprenorphine.

DISCUSSION/CONCLUSION

It is hoped that this trial will provide a rich source of data on management of patients discontinuing medication for opioid use disorder (MOUD) to inform future research and practice. The trial will shed light on which strategies are most likely to lead to long-term success (absence of relapse), and what participant characteristics distinguish those who can safely discontinue MOUD from those who remain at risk of relapse should they discontinue.

Attitudes toward medications for opioid use disorder among peer recovery specialists

Background: Peer recovery specialists (PRSs) are substance use service providers with lived experience in recovery. Although a large body of research demonstrates the efficacy of medications for opioid use disorder (MOUD), emerging research suggests PRSs' attitudes toward MOUD are ambivalent or mixed. Few studies have quantitatively assessed factors influencing PRSs' attitudes.Objectives: This study identifies personal and professional characteristics associated with attitudes toward MOUD among PRSs.Methods: PRSs working at publicly funded agencies in Michigan completed a self-administered web-based survey (N = 266, 60.5% women). Surveys assessed socio-demographics, treatment and recovery history, attitudes toward clients, and attitudes toward MOUD. Multiple linear regression was used to identify factors associated with attitudes toward MOUD.Results: A minority of PRSs (21.4%) reported a history of treatment with MOUD, while nearly two-thirds reported current 12-step involvement (62.5%). Compared to PRSs without a history of MOUD treatment, PRSs who had positive (b = 4.71, p < .001) and mixed (b = 3.36, p = .010) experiences with MOUD had more positive attitudes; PRSs with negative experiences with MOUD had less positive attitudes (b = -3.16, p = .003). Current 12-step involvement (b = -1.63, p = .007) and more stigmatizing attitudes toward clients (b = -.294, p < .001) were associated with less positive attitudes toward MOUD. Black PRSs had less positive attitudes than White PRSs (b = -2.50, p = .001), and women had more positive attitudes than men (b = 1.19, p = .038).Conclusion: PRSs' attitudes toward MOUD varied based on the nature of their lived experience. Findings highlight considerations for training and supervising PRSs who serve individuals with opioid use disorder.

The development of a recovery coaching training curriculum to facilitate linkage to and increase retention on medications for opioid use disorder

Introduction

Medication treatment for opioid use disorder (MOUD) decreases opioid overdose risk and is the standard of care for persons with opioid use disorder (OUD). Recovery coach (RC)-led programs and associated training curriculums to improve outcomes around MOUD are limited. We describe our comprehensive training curriculum including instruction and pedagogy for novel RC-led MOUD linkage and retention programs and report on its feasibility.

Methods–pedagogy and training development

The Kentucky HEALing (Helping to End Addiction Long-termSM) Communities Study (HCS) created the Linkage and Retention RC Programs with a local recovery community organization, Voices of Hope-Lexington. RCs worked to reduce participant barriers to entering or continuing MOUD, destigmatize and educate on MOUD and harm reduction (e.g., safe injection practices), increase recovery capital, and provide opioid overdose education with naloxone distribution (OEND). An extensive hybrid (in-person and online, both synchronous and asynchronous), inclusive learning-focused curriculum to support the programs (e.g., motivational interviewing sessions, role plays, MOUD competency assessment, etc.,) was created to ensure RCs developed the necessary skills and could demonstrate competency before deployment in the field. The curriculum, pedagogy, learning environment, and numbers of RCs trained and community venues receiving a trained RC are reported, along with interviews from three RCs about the training program experience.

Results

The curriculum provides approximately 150 h of training to RCs. From December 2020 to February 2023, 93 RCs and 16 supervisors completed the training program; two were unable to pass a final competency check. RCs were deployed at 45 agencies in eight Kentucky HCS counties. Most agencies (72%) sustained RC services after the study period ended through other funding sources. RCs interviewed reported that the training helped them better explain and dispel myths around MOUD.

Conclusion

Our novel training and MOUD programs met a current unmet need for the RC workforce and for community agencies. We were able to train and deploy RCs successfully in these new programs aimed at saving lives through improving MOUD linkage and retention. This paper addresses a need to enhance the training requirements around MOUD for peer support specialists.

Quality of life and associated factors of heroin-dependent patients receiving methadone and buprenorphine maintenance treatment

AIM

Although studies in Western countries have investigated the quality of life (QoL) of heroin users, limited research on this topic has been conducted in Asia. The present study assessed QoL in patients with heroin dependence receiving medications to treat opioid use disorder.

METHODS

We performed a cross-sectional study of patients with heroin dependence receiving methadone and buprenorphine treatment. The demographic and substance use variables of patients receiving methadone and buprenorphine were compared. The Chinese Health Questionnaire (CHQ-12), Obsessive Compulsive Drug Use Scale (OCDUS), and World Health Organization Quality of Life Short Form Taiwan version (WHOQOL-BREF-T) were administered to measure patient mental health problems, addiction severity, and QoL, respectively. Multivariate regression was used to identify the factors associated with QoL.

RESULTS

A total of 149 patients receiving methadone and 31 receiving buprenorphine completed the questionnaires. Individuals in the buprenorphine group were more likely to be married (p = 0.024) or employed (p = 0.024), have a higher educational level (p = 0.013), have lower drug craving (OCDUS: p = 0.035), or have higher QoL (WHOQOL-BREF-T: p = 0.004) than those in the methadone group. After adjustment for other variables, employment was positively associated with the physical, psychological, and environmental domains of QoL. Receiving buprenorphine treatment (p = 0.032) and longer treatment duration (p = 0.016) were associated with higher psychological QoL.

CONCLUSION

Several factors were associated with QoL in patients with heroin dependence. Some measures may improve their QoL, such as reducing employment barriers, improving treatment adherence, or increasing accessibility to buprenorphine treatment.

Caring for Our Patients With Opioid Use Disorder in the Perioperative Period: A Guide for the Anesthesiologist

Opioid use disorder (OUD) is a rising public health crisis, impacting millions of individuals and families worldwide. Anesthesiologists can play a key role in improving morbidity and mortality around the time of surgery by informing perioperative teams and guiding evidence-based care and access to life-saving treatment for patients with active OUD or in recovery. This article serves as an educational resource for the anesthesiologist caring for patients with OUD and is the second in a series of articles published in Anesthesia & Analgesia on the anesthetic and analgesic management of patients with substance use disorders. The article is divided into 4 sections: (1) background to OUD, treatment principles, and the anesthesiologist; (2) perioperative considerations for patients prescribed medications for OUD (MOUD); (3) perioperative considerations for patients with active, untreated OUD; and (4) nonopioid and nonpharmacologic principles of multimodal perioperative pain management for patients with untreated, active OUD, or in recovery. The article concludes with a stepwise approach for the anesthesiologist to support OUD treatment and recovery. The anesthesiologist is an important leader of the perioperative team to promote these suggested best practices and help save lives.

Transitioning off methadone: A qualitative study exploring why patients discontinue methadone treatment for opioid use disorder

INTRODUCTION

Patients who discontinue methadone for opioid use disorder are at increased risk of overdose and death. We know little about how patients make the decision to stop treatment. This study explored reasons why patients discontinue methadone treatment.

METHODS

We conducted 20 individual semi-structured patient interviews and two staff focus groups, each with five participants, at two opioid treatment programs in Baltimore, MD, in the United States from June 2021 to May 2022. Patient interviews and staff focus groups covered three domains: 1) reasons why patients may want to discontinue methadone; 2) perspectives about the ideal length of methadone treatment; and 3) changes that could improve retention. We used a modified grounded theory approach to code interviews, identify emergent themes, and develop a conceptual model.

RESULTS

We identified three themes related to patients' internal relationships to methadone: patients (1) viewed methadone as a bridge to opioid-free recovery, (2) believed that long-term methadone damages the body, and (3) felt that methadone increases craving for cocaine; and three themes related to their external relationships with opioid treatment programs and society at large: patients (4) viewed daily dosing as burdensome, (5) feared methadone inaccessibility could trigger relapse, and (6) experienced stigma from friends, family, and peers. Patients with internal reasons planned to stop as soon as possible and asked for education about perceived side effects and treatment for cocaine craving to promote retention. Patients with external reasons were willing to continue for longer and asked for adaptive take-home policies and reduced societal stigma around methadone.

CONCLUSIONS

Patients want to discontinue methadone either because of their internal relationship to methadone and its real or perceived side effects, or because of their external experiences with opioid treatment programs and societal stigma of methadone. To improve retention, clinical and policy changes should consider responses to both of these categories of reasons.

Drug use patterns and factors related to the use and discontinuation of medications for opioid use disorder in the age of fentanyl: findings from a mixed-methods study of people who use drugs

BACKGROUND

Medications for opioid use disorder (MOUD; methadone, buprenorphine, naltrexone) are the most effective treatments for OUD, and MOUD is protective against fatal overdoses. However, continued illegal drug use can increase the risk of treatment discontinuation. Given the widespread presence of fentanyl in the drug supply, research is needed to understand who is at greatest risk for concurrent MOUD and drug use and the contexts shaping use and treatment discontinuation.

METHODS

From 2017 to 2020, Massachusetts residents with past-30-day illegal drug use completed surveys (N = 284) and interviews (N = 99) about MOUD and drug use. An age-adjusted multinomial logistic regression model tested associations between past-30-day drug use and MOUD use (current/past/never). Among those on methadone or buprenorphine (N = 108), multivariable logistic regression models examined the association between socio-demographics, MOUD type; and past-30-day use of heroin/fentanyl; crack; benzodiazepines; and pain medications. Qualitative interviews explored drivers of concurrent drug and MOUD use.

RESULTS

Most (79.9%) participants had used MOUD (38.7% currently; 41.2% past), and past 30-day drug use was high: 74.4% heroin/fentanyl; 51.4% crack cocaine; 31.3% benzodiazepines, and 18% pain medications. In exploring drug use by MOUD history, multinomial regression analyses found that crack use was positively associated with past and current MOUD use (outcome referent: never used MOUD); whereas benzodiazepine use was not associated with past MOUD use but was positively associated with current use. Conversely, pain medication use was associated with reduced odds of past and current MOUD use. Among those on methadone or buprenorphine, separate multivariable logistic regression models found that benzodiazepine and methadone use were positively associated with heroin/fentanyl use; living in a medium-sized city and sex work were positively associated with crack use; heroin/fentanyl use was positively associated with benzodiazepine use; and witnessing an overdose was inversely associated with pain medication use. Many participants qualitatively reported reducing illegal opioid use while on MOUD, yet inadequate dosage, trauma, psychological cravings, and environmental triggers drove their continued drug use, which increased their risk of treatment discontinuation and overdose.

CONCLUSIONS

Findings highlight variations in continued drug use by MOUD use history, reasons for concurrent use, and implications for MOUD treatment delivery and continuity.

Facilitating factors and barriers for use of medications to treat opioid use disorder (MOUD) among justice-involved individuals in rural Appalachia

The purpose of this qualitative study is to assess facilitating factors and barriers for medications to treat opioid use disorder (MOUD) initiation among justice-involved individuals in one rural Appalachian community, as well as how those factors may differ across the three types of Food and Drug Administration (FDA) approved medications. Qualitative interviews were conducted with rural justice-involved individuals (N = 10) with a history of opioid use in the target community. Overall, participants demonstrated knowledge of the different types of MOUD and their pharmacological properties, but limited overall health literacy around opioid use disorder and MOUD treatment. Treatment access was hampered by transportation, time burdens, and costs. Findings call for research into improving health literacy education, training, and resources to decrease stigma and increase access to MOUD, particularly in light of the ongoing opioid crisis. State policies also need to increase access to all FDA medications among justice-involved individuals, as well as supporting a care continuum from facility entry, release, and community re-entry.

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.

A Prospective Three-Months Naturalistic Follow-Up Study of Outcomes of Patients with Opioid Dependence Discharged on Buprenorphine or Oral Naltrexone

BACKGROUND

Comparative studies of the naturalistic course of patients of opioid dependence on naltrexone and buprenorphine are likely to be helpful for clinical decision-making. The article aimed to report on the three-months naturalistic outcomes of patients discharged on naltrexone or buprenorphine from the same center.

METHODS

Patients with opioid dependence who were discharged on either naltrexone (n = 86) or buprenorphine (n = 30) were followed up for three months for retention in treatment. The patients were also followed up telephonically, and the Maudsley Addiction Profile was applied.

RESULTS

The days of retention in treatment were significantly higher in the buprenorphine group (69.5 versus 48.7 days, P = 0.009). Heroin use, pharmaceutical opioid use, injection drug use, involvement in illegal activity, and percentage of contact days in conflict with friends in the last 30 days reduced over three months in both the groups, while the physical and psychological quality of life improved in both the groups. Additionally, in the naltrexone group, smoked tobacco use, cannabis use, and percentage of contact days in conflict with family within the last 30 days reduced at three months compared to baseline.

CONCLUSION

With the possible limitations of choice of medication-assisted treatment for opioid dependence being determined by the patient, and prescribing related factors and sample size constraints, the study suggests that retention outcomes may vary between naltrexone and buprenorphine, though both medications may improve several patient-related parameters. However, a true head-to-head comparison of the outcomes of buprenorphine and naltrexone in a naturalistic setting may be difficult.

Comprehensive analysis of discharge reasons from methadone outpatient treatment programs

BACKGROUND AND OBJECTIVES

Methadone treatment (MT) for opioid use disorder is only available in opioid treatment programs (OTPs) in the United States, with retention predictive of positive health outcomes. OTP discharge reason information is needed to develop interventions for facilitating MT retention. We sought to identify discharge reason frequencies and associations between discharge reasons and facility/county-level characteristics.

METHODS

We examined annual OTP discharge reasons for all Florida OTPs from 2014 to 2017 (n = 44,774 discharges). We used multinomial logistic regression analysis to examine associations between patients' discharge reasons and (1) facility-level characteristics (e.g., size, funding type) and (2) county-level characteristics (e.g., race/ethnicity, overdose rates).

RESULTS

Lost contact was the most common discharge reason (29%). Only 11% of patients were discharged for treatment completion, with the proportion one-third as low in privately versus publicly-funded OTPs (p < .001). Privately-funded OTPs had a patient share self-terminating treatment against medical advice about 3.5 times higher than publicly-funded OTPs. Inability to pay accounted for 7% of OTP discharges. Noncompliant discharges represented 6% and were more common in counties with larger proportions of Black residents (p < .01). Counties with higher drug overdose rates had significantly more discharges for noncompliance or self-terminating against medical advice (p < .01 and p < .05).

DISCUSSION AND CONCLUSIONS

Statewide differences in discharge reasons exist between publicly and privately-funded OTPs, possibly reflecting differences in funding incentives and state oversight. State agencies should develop consistent approaches for collecting/reporting discharge reasons.

SCIENTIFIC SIGNIFICANCE

Our study is the first to examine the relationship between OTP funding type and discharge reasons.

Access to methadone clinics and opioid overdose deaths in Georgia: A geospatial analysis

BACKGROUND

As a result of the opioid epidemic, the demand for treatment options for opioid use disorder (OUD) such as methadone has increased. Methadone can only be administered in methadone clinics. Though numerous methadone clinics are located across the state of Georgia, access to methadone treatment may still be a concern for certain areas of the state. In this study, we examine the relationship between access to methadone clinics and opioid overdose death rates at the county level and compare access to treatment through Federally Qualified Health Centers (FQHCs) if methadone provision was to expand in Georgia.

METHODS

We utilize location data for methadone clinics and FQHCs, and opioid overdose death rates at the county level from 2019 for the study analysis. The analysis was carried out using a geographical information system (GIS) mapping and a descriptive analysis.

RESULTS

The results show that there is no methadone clinic accessible to individuals within a 15-minute drive time for 4 out of the 5 counties with the highest opioid overdose death rates in Georgia, though FQHCs are accessible within a 15-minute drive time to more than 67% of the population in each of these counties. Additionally, 7 out of the 9 counties with the highest opioid overdose death rates have no methadone clinic accessible within a 15-minute drive time, though all those counties have easier access to FQHCs.

CONCLUSION

If methadone distribution was to expand to FQHCs, more counties and a larger area of Georgia would have greater access to methadone treatment.

Individual, interpersonal, and neighborhood measures associated with opioid use stigma: Evidence from a nationally representative survey

Despite growing awareness of opioid use disorder (OUD), fatal overdoses and downstream health conditions (e. g., hepatitis C and HIV) continue to rise in some populations. Various interrelated structural forces, together with social and economic determinants, contribute to this ongoing crisis; among these, access to medications for opioid use disorder (MOUD) and stigma towards people with OUD remain understudied. We combined data on methadone, buprenorphine, and naltrexone providers from SAMHSA’s 2019 directory, additional naltrexone providers from Vivitrol’s location finder service, with a nationally representative survey called “The AmeriSpeak survey on stigma toward people with OUD.” Integrating the social-ecological framework, we focus on individual characteristics, personal and family members’ experience with OUD, and spatial access to MOUD at the community level. We use nationally representative survey data from 3008 respondents who completed their survey in 2020. Recognizing that stigma is a multifaceted construct, we also examine how the process varies for different types of stigma, specifically perceived dangerousness and untrustworthiness, as well as social distancing measures under different scenarios. We found a significant association between stigma and spatial access to MOUD — more resources are related to weaker stigma. Respondents had a stronger stigma towards people experiencing current OUD (versus past OUD), and they were more concerned about OUD if the person would marry into their family (versus being their coworkers). Additionally, respondents’ age, sex, education, and personal experience with OUD were also associated with their stigma, and the association can vary depending on the specific type of stigma. Overall, stigma towards people with OUD was associated with both personal experiences and environmental measures.

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.

Treatment outcomes associated with medications for opioid use disorder (MOUD) among criminal justice-referred admissions to residential treatment in the U.S., 2015-2018

AIMS

To examine the use and association of medications for opioid use disorder (MOUD) with treatment completion and retention for criminal justice referred (CJR) admissions to residential treatment.

METHODS

A retrospective analysis of the Treatment Episode Dataset-Discharge (TEDS-D; 2015-2018) for adults (N = 205,348) admitted to short-term (ST) (< 30 days) or long-term (LT) (>30 days) residential treatment for OUD. Outcomes were MOUD in treatment plans, and treatment completion and retention (ST >10 days; LT > 90 days). Logistic regression analyses were conducted separately for ST and LT settings.

RESULTS

CJR admissions were less likely to have MOUD than non-CJR admissions (ST, 11% vs. 21%; LT, 10% vs. 24%, respectively) and were more likely to complete and be retained in treatment. In ST settings, MOUD was associated with higher likelihood of treatment completion and retention. In LT settings, MOUD was associated with higher likelihood of treatment retention and lower likelihood of treatment completion. These associations tended to be slightly weaker for CJR admissions, with the exception of treatment completion in LT settings, but the moderating effect size of CJR status in all models was very small. Small differences in the moderating effect of CJR status by race and ethnicity were observed in LT settings.

CONCLUSIONS

MOUD is greatly under-utilized for CJR patients, and given that MOUD was associated with positive outcomes, there is a critical need to find ways to increase access to MOUD for CJR patients in residential treatment. Race and ethnicity appear to have relatively little impact on outcomes.

Treatment preference for opioid use disorder among people who are incarcerated

INTRODUCTION

The devastating overdose crisis remains a leading cause of death in the United States, especially among individuals involved in the criminal legal system. Currently, three classes (opioid agonist, partial agonist-antagonist, and antagonist) of FDA-approved medications for opioid use disorder (MOUD) exist, yet few correctional settings offer any medication treatment for people who are incarcerated. Facilities that do often provide only one medication.

METHODS

We conducted 40 semi-structured qualitative interviews with individuals receiving MOUD incarcerated at the Rhode Island Department of Corrections.

RESULTS

Results from this study indicate that people who are incarcerated have preferences for certain types of MOUD. Individuals' preferences were influenced by medication side effects, route of administration, delivery in the community, and stigma.

CONCLUSION

MOUD programs in the community and in correctional settings should use a patient-centered approach that allows choice of medication by offering all FDA-approved MOUD treatment options.

Identifying and Characterizing Medical Advice-Seekers on a Social Media Forum for Buprenorphine Use

Background: Online communities such as Reddit can provide social support for those recovering from opioid use disorder. However, it is unclear whether and how advice-seekers differ from other users. Our research addresses this gap by identifying key characteristics of r/suboxone users that predict advice-seeking behavior. Objective: The objective of this analysis is to identify and describe advice-seekers on Reddit for buprenorphine-naloxone use using text annotation, social network analysis, and statistical modeling techniques. Methods: We collected 5258 posts and their comments from Reddit between 2014 and 2019. Among 202 posts which met our inclusion criteria, we annotated each post to determine which were advice-seeking (n = 137) or not advice-seeking (n = 65). We also annotated each posting user’s buprenorphine-naloxone use status (current versus formerly taking and, if currently taking, whether inducting or tapering versus other stages) and quantified their connectedness using social network analysis. To analyze the relationship between Reddit users’ advice-seeking and their social connectivity and medication use status, we constructed four models which varied in their inclusion of explanatory variables for social connectedness and buprenorphine use status. Results: The stepwise model containing “total degree” (p = 0.002), “using: inducting/tapering” (p < 0.001), and “using: other” (p = 0.01) outperformed all other models. Reddit users with fewer connections and who are currently using buprenorphine-naloxone are more likely to seek advice than those who are well-connected and no longer using the medication, respectively. Importantly, advice-seeking behavior is most accurately predicted using a combination of network characteristics and medication use status, rather than either factor alone. Conclusions: Our findings provide insights for the clinical care of people recovering from opioid use disorder and the nature of online medical advice-seeking overall. Clinicians should be especially attentive (e.g., through frequent follow-up) to patients who are inducting or tapering buprenorphine-naloxone or signal limited social support.

Modeling the population-level impact of opioid agonist treatment on mortality among people accessing treatment between 2001 and 2020 in New South Wales, Australia

BACKGROUND AND AIMS

The individual-level effectiveness of opioid agonist treatment (OAT) in reducing mortality is well established, but there is less evidence on population-level benefits. We use modeling informed with linked data from the OAT program in New South Wales (NSW), Australia, to estimate the impact of OAT provision in the community and prisons on mortality and the impact of eliminating excess mortality during OAT initiation/discontinuation.

DESIGN

Dynamic modeling.

SETTING AND PARTICIPANTS

A cohort of 49 359 individuals who ever received OAT in NSW from 2001 to 2018.

MEASUREMENTS

Receipt of OAT was represented through five stages: (i) first month on OAT, (ii) short (1-9 months) and (iii) longer (9+ months) duration on OAT, (iv) first month following OAT discontinuation and (v) rest of time following OAT discontinuation. Incarceration was represented as four strata: (i) never or not incarcerated in the past year, (ii) currently incarcerated, (iii) released from prison within the past month and (iv) released from prison 1-12 months ago. The model incorporated elevated mortality post-release from prison and OAT impact on reducing mortality and incarceration.

FINDINGS

Among the cohort, mortality was 0.9 per 100 person-years, OAT coverage and retention remained high (> 50%, 1.74 years/episode). During 2001-20, we estimate that OAT provision reduced overdose and other cause mortality among the cohort by 52.8% [95% credible interval (CrI) = 49.4-56.9%] and 26.6% (95% CrI =22.1-30.5%), respectively. We estimate 1.2 deaths averted and 9.7 life-years gained per 100 person-years on OAT. Prison OAT with post-release OAT-linkage accounted for 12.4% (95% CrI = 11.5-13.5%) of all deaths averted by the OAT program, primarily through preventing deaths in the first month post-release. Preventing elevated mortality during OAT initiation and discontinuation could have averted up to 1.4% (95% CrI =  0.8-2.0%) and 3.0% (95% CrI = 2.1-5.3%) of deaths, respectively.

CONCLUSION

The community and prison opioid agonist treatment program in New South Wales, Australia appears to have substantially reduced population-level overdose and all-cause mortality in the past 20 years, partially due to high retention.

Assessment of Community-Level Vulnerability and Access to Medications for Opioid Use Disorder

IMPORTANCE

Given that COVID-19 and recent natural disasters exacerbated the shortage of medication for opioid use disorder (MOUD) services and were associated with increased opioid overdose mortality, it is important to examine how a community's ability to respond to natural disasters and infectious disease outbreaks is associated with MOUD access.

OBJECTIVE

To examine the association of community vulnerability to disasters and pandemics with geographic access to each of the 3 MOUDs and whether this association differs by urban, suburban, or rural classification.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study of zip code tabulation areas (ZCTAs) in the continental United States excluding Washington, DC, conducted a geospatial analysis of 2020 treatment location data.

EXPOSURES

Social vulnerability index (US Centers for Disease Control and Prevention measure of vulnerability to disasters or pandemics).

MAIN OUTCOMES AND MEASURES

Drive time in minutes from the population-weighted center of the ZCTA to the ZCTA of the nearest treatment location for each treatment type (buprenorphine, methadone, and extended-release naltrexone).

RESULTS

Among 32 604 ZCTAs within the continental US, 170 within Washington, DC, and 20 without an urban-rural classification were excluded, resulting in a final sample of 32 434 ZCTAs. Greater social vulnerability was correlated with longer drive times for methadone (correlation, 0.10; 95% CI, 0.09 to 0.11), but it was not correlated with access to other MOUDs. Among rural ZCTAs, increasing social vulnerability was correlated with shorter drive times to buprenorphine (correlation, -0.10; 95% CI, -0.12 to -0.08) but vulnerability was not correlated with other measures of access. Among suburban ZCTAs, greater vulnerability was correlated with both longer drive times to methadone (correlation, 0.22; 95% CI, 0.20 to 0.24) and extended-release naltrexone (correlation, 0.15; 95% CI, 0.13 to 0.17).

CONCLUSIONS AND RELEVANCE

In this study, communities with greater vulnerability did not have greater geographic access to MOUD, and the mismatch between vulnerability and medication access was greatest in suburban communities. Rural communities had poor geographic access regardless of vulnerability status. Future disaster preparedness planning should match the location of services to communities with greater vulnerability to prevent inequities in overdose deaths.

Characteristics and treatment preferences of individuals with opioid use disorder seeking to transition from buprenorphine to extended-release naltrexone in a residential setting

Background and Objectives

Treatment for individuals receiving medication for opioid use disorder (MOUD) should follow an informed patient‐centered approach. To better support patient autonomy in the decision‐making process, clinicians should be aware of patient preferences and be prepared to educate and assist patients in transitioning from one MOUD to another, when clinically indicated. This posthoc analysis describes the characteristics of clinical trial participants (NCT02696434) with a history of opioid use disorder (OUD) seeking to transition from buprenorphine (BUP) to extended‐release naltrexone (XR‐NTX).

Methods

The posthoc analysis included adults with OUD currently receiving BUP (≤8 mg/day) and seeking transition to XR‐NTX (N = 101) in a residential setting. Baseline participant characteristics and OUD treatment history were reviewed. All patients completed a screening questionnaire that asked about their reasons for seeking transition to XR‐NTX and for choosing BUP.

Results

The most common reasons for initiating a transition to XR‐NTX were “Seeking to be opioid‐free” (63.4%) and “Tired of daily pill taking” (25.7%). Positive predictors of transition included a more extensive BUP treatment history and a history of prescription opioid abuse. Most participants stated they were not aware of XR‐NTX as a treatment option when initiating BUP (78.2%).

Discussions and Conclusions

Patients' reasons for seeking XR‐NTX transition, more extensive BUP treatment history, and a history of prescription opioid abuse, may positively predict outcomes.

Scientific Significance

These findings may assist clinicians in optimizing outcomes of the BUP to XR‐NTX transition and supporting patients to make better informed MOUD decisions.

Nonstigmatizing and Precise Terminology to Describe Processes and Outcomes in Addiction Medicine

ABSTRACT

Scholarly journals and professional organizations in addiction medicine have recently discussed the importance of adopting nonstigmatizing and precise terminology. The present commentary expands that ongoing discussion to terms related to treatment processes and outcomes. Four implicit assumptions of stigmatizing and imprecise terms related to treatment processes and outcomes are overviewed, and research evidence against these assumptions is presented. The commentary ends with recommendations for the use of positive behavioral indicators of processes and outcomes and, more importantly, accompanying them with nonevaluative, objective descriptors of patients' behaviors.

Therapeutic relationships between Veterans and buprenorphine providers and effects on treatment retention

OBJECTIVE

To examine the extent to which there was any therapeutic relationship between Veterans and their initial buprenorphine provider and whether the presence of this relationship influenced treatment retention.

DATA SOURCES

National, secondary administrative data used from the Veterans Health Administration (VHA), 2008-2017.

STUDY DESIGN

Retrospective cohort study. The primary exposure was a therapeutic relationship between the Veteran and buprenorphine provider, defined as the presence of a previous visit or medication prescribed by the provider in the 2 years preceding buprenorphine treatment initiation. The primary outcome was treatment discontinuation, evaluated as 14 days of absence of medication from initiation through 1 year.

DATA COLLECTION/EXTRACTION METHODS

Adult Veterans (age ≥ 18 years) diagnosed with opioid use disorder and treated with buprenorphine or buprenorphine/naloxone within the VHA system were included in this study. We excluded those receiving buprenorphine patches, those with documentation of a metastatic tumor diagnosis within 2 years prior to buprenorphine initiation, and those without geographical information on rurality.

PRINCIPAL FINDINGS

A total of 28,791 Veterans were included in the study. Within the overall study sample, 56.3% (n = 16,206) of Veterans previously had at least one outpatient encounter with their initial buprenorphine provider, and 24.9% (n = 7174) of Veterans previously had at least one prescription from that provider in the 2 years preceding buprenorphine initiation. There was no significant or clinically meaningful association between therapeutic relationship history and treatment retention when defined as visit history (aHR: 0.99; 95% CI: 0.96, 1.02) or medication history (aHR: 1.03; 95% CI: 1.00, 1.07).

CONCLUSIONS

Veterans initiating buprenorphine frequently did not have a therapeutic history with their initial buprenorphine provider, but this relationship was not associated with treatment retention. Future work should investigate how the quality of Veteran-provider therapeutic relationships influences opioid use dependence management and whether eliminating training requirements for providers might affect access to buprenorphine, and subsequently, treatment initiation and retention.

'Not at all what I had expected': Discontinuing treatment with extended-release naltrexone (XR-NTX): A qualitative study

BACKGROUND

Extended-release naltrexone (XR-NTX), an opioid antagonist, has demonstrated equal treatment outcomes, in terms of safety, opioid use, and retention, to the recommended OMT medication buprenorphine. However, premature discontinuation of XR-NTX treatment is still common and poorly understood. Research on patient experiences of XR-NTX treatment is limited. We sought to explore participants' experiences with discontinuation of treatment with XR-NTX, particularly motivation for XR-NTX, experiences of initiation and treatment, and rationale for leaving treatment.

METHODS

We conducted qualitative, semi-structured interviews with participants from a clinical trial of XR-NTX. The study participants (N = 13) included seven women and six men with opioid dependence, who had received a minimum of one and maximum of four injections of XR-NTX. The study team analyzed transcribed interviews, employing thematic analysis with a critical realist approach.

FINDINGS

The research team identified three themes, and we present them as a chronological narrative: theme 1: Entering treatment - I thought I knew what I was going into; theme 2: Life with XR-NTX - I had something in me that I didn't want; and theme 3: Leaving treatment - I want to go somewhere in life. Patients' unfulfilled expectations of how XR-NTX would lead to a better life were central to decisions about discontinuation, including unexpected physical, emotional, or mental reactions as well as a lack of expected effects, notably some described an opioid effect from buprenorphine. A few participants ended treatment because they had reached their treatment goal, but most expressed disappointment about not achieving this goal. Some also expressed renewed acceptance of OMT. The participants' motivation for abstinence from illegal substances generally remained.

CONCLUSION

Our findings emphasize that a dynamic understanding of discontinuation of treatment is necessary to achieve a long-term approach to recovery: the field should understand discontinuation as a feature of typical treatment trajectories, and discontinuation can be followed by re-initiation of treatment.

Methadone and suboxone® mentions on twitter: thematic and sentiment analysis

BACKGROUND

According to the latest medical evidence, Methadone and buprenorphine-naloxone (Suboxone®) are effective treatments for opioid use disorder (OUD). While the evidence basis for the use of these medications is favorable, less is known about the perceptions of the general public about them.

OBJECTIVE

This study aimed to use Twitter to assess the public perceptions about methadone and buprenorphine-naloxone, and to compare their discussion contents based on themes/topics, subthemes, and sentiment.

METHODS

We conducted a descriptive analysis of a small and automatic analysis of a large volume of microposts ("tweets") that mentioned "methadone" or "suboxone". In the manual analysis, we categorized the tweets into themes and subthemes, as well as by sentiment and personal experience, and compared the information posted about these two medications. We performed automatic topic modeling and sentiment analysis over large volumes of posts and compared the outputs to those from the manual analyses.

RESULTS

We manually analyzed 900 tweets, most of which related to access (15.3% for methadone; 14.3% for buprenorphine-naloxone), stigma (17.0%; 15.5%), and OUD treatment (12.8%; 15.6%). Only a small proportion of tweets (16.4% for Suboxone® and 9.3% for methadone) expressed positive sentiments about the medications, with few tweets describing personal experiences. Tweets mentioning both medications primarily discussed MOUD broadly, rather than comparing the two medications directly. Automatic topic modeling revealed topics from the larger dataset that corresponded closely to the manually identified themes, but sentiment analysis did not reveal any notable differences in chatter regarding the two medications.

CONCLUSIONS

Twitter content about methadone and Suboxone® is similar, with the same major themes and similar sub-themes. Despite the proven effectiveness of these medications, there was little dialogue related to their benefits or efficacy in the treatment of OUD. Perceptions of these medications may contribute to their underutilization in combatting OUDs.

Qualitative characterizations of misinformed disclosure reactions to medications for opioid use disorders and their consequences

INTRODUCTION

Methadone and buprenorphine/naloxone medications are among the most effective treatment options for opioid use disorders, yet many people remain misinformed about their benefits and hold negative perceptions about the use of medications to treat opioid use disorders. Such perceptions, especially negative perceptions based on misinformation, may be especially harmful or stigmatizing within the context of disclosure (i.e., telling another about one's opioid use disorder history or treatment), inhibiting important recovery outcomes and sources of social support.

METHODS

Therefore, using the Disclosure Process Model as a framework, the current study seeks to characterize and compare participants' perceptions of stigmatizing reactions to their disclosures of MOUD use that stem from misinformation about methadone or buprenorphine/naloxone. Participants included people who are actively receiving MOUD as treatment.

RESULTS

Results suggest that participants (N = 52) receiving both types of medications experienced similar stigmatizing reactions to disclosures. Participants also reported treatment consequences of misinformed reactions to their disclosure, such as dropping out of support groups (e.g., Narcotics Anonymous) or prematurely ending their medication use. Further, the paper provides participants' recommendations for avoiding or managing misinformed disclosure reactions.

CONCLUSIONS

Short-term intervention efforts may promote strategies to manage misinformation, equipping individuals to respond to misinformation surrounding their medication use. Long-term interventions may target misinformation about methadone and buprenorphine/naloxone medications to increase health literacy, reduce stigma, and combat cultural ambivalence within communities, as well as promote recovery among people receiving medications for opioid use disorder.

Buprenorphine Naloxone and Extended Release Injectable Naltrexone for the Treatment of Opioid Use Disorder Among a Veteran Patient Sample: A Retrospective Chart Review

Previous research has demonstrated the effectiveness of both extended-release injectable naltrexone (XR-NTX) and buprenorphine/naloxone (BUP-NX) in the treatment of opioid use disorder (OUD). However, studies using real-world samples with multiple medical and psychiatric comorbidities are lacking. The study's primary aims were to: (1) compare clinical presentations in an inclusive sample of OUD-diagnosed US military veterans receiving XR-NTX and BUP-NX, and (2) investigate differences in 90-day treatment outcomes between these two groups. Methods: The medical records of 79 patients receiving medications to treat OUD in a VA hospital's addiction outpatient treatment program were reviewed retrospectively. The analysis included all veterans who initiated medication treatment during the study period. Differences between medication groups on co-occurring diagnoses, treatment retention, and related outcomes were examined. Results: The two groups were similar in medical and psychiatric comorbidity, although the BUP-NX group were more likely to have a pain diagnosis. No statistically significant differences in retention or toxicology results were found between the two groups over the 90-day study period. The rate of positive urine screens for the BUP-NX group was 19.2% for opiates and 13.5% for other illicit substances, and 3.7% and 11.1% respectively for the XR- NTX group. Conclusion: There was no evidence that 90-days outcomes differed for veterans based on medication received, and there were more similarities than differences in clinical characteristics. Additional research is needed, including larger sample size and prospective randomized control trial to evaluate VA patients' treatment outcomes receiving BUP-NX or XR-NTX for OUD.

Plausibility of patient-centred care in high-intensity methadone treatment: reflections of providers and patients

Background

Patients with opioid use disorder (OUD) often have complex health care needs. Methadone is one of the medications for opioid use disorder (MOUD) used in the management of OUDs. Highly restrictive methadone treatment—which requires patient compliance with many rules of care—often results in low retention, especially if there is inadequate support from healthcare providers (HCPs). Nevertheless, HCPs should strive to offer patient-centred care (PCC) as it is deemed the gold standard to care. Such an approach can encourage patients to be actively involved in their care, ultimately increasing retention and yielding positive treatment outcomes.

Methods

In this secondary analysis, we aimed to explore how HCPs were applying the principles of PCC when caring for patients with OUD in a highly restrictive, biomedical and paternalistic setting. We applied Mead and Bower’s PCC framework in the secondary analysis of 40 in-depth, semi-structured interviews with both HCPs and patients.

Results

We present how PCC's concepts of; (a) biopsychosocial perspective; (b) patient as a person; (c) sharing power and responsibility; (d) therapeutic alliance and (e) doctor as a person—are applied in a methadone treatment program. We identified both opportunities and barriers to providing PCC in these settings.

Conclusion

In a highly restrictive methadone treatment program, full implementation of PCC is not possible. However, implementation of some aspects of PCC are possible to improve patient empowerment and engagement with care, possibly leading to increase in retention and better treatment outcomes.

Rapid buprenorphine microdosing for opioid use disorder in a hospitalized patient receiving very high doses of full agonist opioids for acute pain management: Titration, implementation barriers, and strategies to overcomes

Background: Conventional buprenorphine inductions for OUD are clinically useful but require patients to experience mild to moderate opioid withdrawal symptoms to avoid precipitated withdrawal. This may be intolerable/unreasonable for some, which may have precluded successful buprenorphine treatment in the past. Microdosing buprenorphine, allowing for full agonist opioid overlap, has emerged as a clinically useful strategy for those unable to complete conventional buprenorphine induction. However, many questions remain such as preclusions regarding the amount of full agonist opioid overlap, speed of buprenorphine microdose titration, and overcoming implementation barriers in U.S. hospitals. Case presentation: A female between the ages of 30 and 40 with severe OUD admitted to the hospital for IDU-related osteomyelitis wished to begin buprenorphine for OUD. Her hospitalization was subject to premature discharge at any time due to competing interests of potential foreclosure on her home, so buprenorphine needed to be started rapidly for safety and improved outcomes. Due to her significant acute pain requirements managed with full agonist opioids, it was unreasonable to consider conventional buprenorphine induction. Buprenorphine microdose strategy was employed at more rapid titration and previously described in the literature, starting at 1 mg TDD on day 1, 3 mg TDD on day 2, and 8 mg TDD on day 3 with full agonist opioid overlap starting at 1,944 MME tapered down to 473 MME. The patient prematurely left the hospital, at which time buprenorphine 8 mg TDD was held at this dose for days 3-8 while full agonist opioid was tapered from 473 MME to 117 MME. BUP was then further titrated to 8 mg TID. This patient tolerated buprenorphine microdosing well, without any treatment-emergent opioid symptoms or worsening of baseline symptoms. Discussion: This case demonstrates the success of buprenorphine microdose induction despite very high doses of full agonist opioid overlap and demonstrates the ability to titrate buprenorphine microdoses faster than originally described. Strategies to overcoming implementation barriers are also discussed.

Strategies to improve implementation of medications for opioid use disorder reported by veterans involved in the legal system: A qualitative study

BACKGROUND

Veterans involved in the legal system have a high risk of overdose mortality but limited utilization of medications for opioid use disorder (MOUD). To increase the use of MOUD in Veterans Health Administration (VHA) facilities and reduce overdose mortality, the VHA should incorporate strategies identified by legal-involved veterans to improve quality of care and ensure that their patients' experiences are integrated into care delivery. This study aims to determine strategies to increase use of MOUD from the perspective of legal-involved veterans with a history of opioid use or opioid use disorder (OUD).

METHODS

Between February 2018 and March 2019, we conducted semistructured interviews with 18 veterans with a history of opioid use or OUD and legal involvement (15 men and 3 women; mean age 41, standard deviation 13, range 28-61). Veterans were from 9 geographically dispersed United States VHA facilities. The study analyzed verbatim transcripts using the framework method. The primary focus was themes that represented legal-involved veteran-identified strategies to improve the use of MOUD.

RESULTS

The 18 veterans interviewed had legal involvement directly related to their opioid use and most (n = 15; 83%) had previously used MOUD. Veteran-identified strategies to improve access to and use of MOUD included: (1) VHA should provide transportation or telehealth services; (2) legal agencies should increase access to MOUD during incarceration; (3) the VHA should reduce physician turnover; (4) the VHA should improve physician education to deliver compassionate, patient-centered treatment; (5) the VHA should improve veteran education about MOUD; and (6) the VHA should provide social support opportunities to veterans.

CONCLUSIONS

Legal-involved veterans provided strategies that can inform and expand MOUD to better meet their needs and the treatment needs of all patients with OUD. The VHA should consider incorporating these strategies into care, and should evaluate their impact on patients' experience, initiation of and retention on medications, and overdose rates.

Barriers and Facilitators to the Use of Medications for Opioid Use Disorder: a Rapid Review

BACKGROUND

Despite evidence that medications to treat opioid use disorder (OUD) are effective, most people who could benefit from this treatment do not receive it. This rapid review synthesizes evidence on current barriers and facilitators to buprenorphine/naloxone and naltrexone at the patient, provider, and system levels to inform future interventions aimed at expanding treatment.

METHODS

We systematically searched numerous bibliographic databases through May 2020 and selected studies published since 2014. Study selection, data abstraction, coding of barriers and facilitators, and quality assessment were first completed by one reviewer and checked by a second.

RESULTS

We included 40 studies of buprenorphine (5 also discussed naltrexone). Four types of patient and provider-level barriers to OUD medication use emerged-stigma related to OUD medications, treatment experiences and beliefs (positive or negative), logistical issues (time and costs as well as insurance and regulatory requirements), and knowledge (high or low) of OUD and the role of medications. Stigma was the most common barrier among patients, while logistical issues were the most common barriers among providers. Facilitators for both patients and providers included peer supports. Most administrator-identified or system-level barriers and facilitators fit into the category of logistical issues. We have moderate confidence in buprenorphine findings but low confidence in naltrexone findings due to the small number of studies.

DISCUSSION

Stigma, treatment experiences, logistical issues, and knowledge gaps are the main barriers associated with low utilization of OUD medications. These barriers can overlap and mutually reinforce each other, but given that, it is plausible that reducing one barrier may lead to reductions in others. The highest priority for future research is to evaluate interventions to reduce stigma. Other priorities for future research include better identification of barriers and facilitators for specific populations, such as those with OUD related to prescription opioids, and for naltrexone use.

Perceptions and preferences for long-acting injectable and implantable medications in comparison to short-acting medications for opioid use disorders

Aim

Treatment for opioid use disorders has recently evolved to include long-acting injectable and implantable formulations of medications for opioid use disorder (MOUD). Incorporating patient preferences into treatment for substance use disorders is associated with increased motivation and treatment satisfaction. This study sought to assess treatment preferences for long-acting injectable and implantable MOUD as compared to short-acting formulations among individuals with OUD.

Methods

We conducted qualitative, semi-structured telephone interviews with forty adults recruited from across the United States through Craigslist advertisements and flyers posted in treatment programs. Eligible participants scored a two or greater on the heroin or opioid pain reliever sections of the Tobacco, Alcohol, Prescription Medications, and Other Substances (TAPS) Tool, indicative of a past-year OUD. Interviews were transcribed, coded, and thematically analyzed.

Results

Twenty-four participants (60%) currently or previously had been prescribed MOUD. Sixteen participants (40%) expressed general opposition to MOUD, citing concerns that MOUD is purely financial gain for pharmaceutical companies and/or a "band aid" solution replacing one drug with another, rather than a path to abstinence. Some participants expressed personal preference for long-acting injectable (n = 16/40: 40%) and implantable formulations (n = 12/40: 30%) over short-acting formulations. About half of the participants were not willing to use injectables (n = 19/40: 48%) or implantables (n = 22/40: 55%), preferring short-acting formulations. Mixed evaluations of long- and short-acting MOUD focused on considerations of medication-related beliefs (privacy, concern over an embedded foreign body), the medication-related burden (convenience, provision of structure and support, medication administration, potential side effects), and medication-taking practices (potential for non-prescribed use, control over dosage, and duration of treatment).

Conclusions

Though many participants personally prefer short-acting to long-acting MOUD, some were open to including long-acting formulations in the range of options for those with OUD. Participants felt long-acting formulations may reduce medication-related burden and the risk of diversion. Conversely, participants expressed concern about invasive administration and loss of control over their treatment. Results suggest support for expanded access to a variety of formulations of MOUD. The use of shared decision making may also help patients select the formulation best aligned with their experiences, values, and treatment goals.
