Opioid relapse and MOUD outcomes following civil commitment for opioid use

The aim of this study was to estimate how ongoing stimulant use affects return to illicit opioid use after initiation onto medication for opioid use disorder (MOUD). This was a secondary analysis of pooled data from two clinical trials comparing buprenorphine (BUP-NX) and extended-release naltrexone (XR-NTX). Thirteen opioid treatment programs and HIV clinics across 10 states in the United States from 2014 to 2019 took part in this study. A total of 528 participants who initiated MOUD as part of trial participation were included. Nearly half (49%) were between 30 and 49 years of age, 69% were male and 66% were non-Hispanic White. The primary outcome was first self-reported day of non-prescribed opioid use following MOUD initiation, and the exposure of interest was daily stimulant use (methamphetamine, amphetamines or cocaine). Both were defined using time-line follow-back. Among participants reporting at least 1day of illicit opioid use, we also examined relapse to ongoing use, defined as (1) 7days of continuous opioid use or (2) 4 consecutive weeks with self-reported opioid use, one or more positive urine drug screens (UDS) for opioids or one or more missing UDS. Forty-seven per cent of participants reported stimulant use following MOUD initiation, 58% returned to illicit opioid use and 66% of those relapsed to ongoing use. Stimulant use was strongly associated with increased risk of misusing opioids after MOUD initiation when measured daily [adjusted hazard ratio (aHR) = 9.23, 95% confidence interval (CI) = 6.80-12.50, P < 0.001] and over a 7-day period (aHR = 1.27 for each additional day, CI = 1.18-1.37, P < 0.001). Using stimulants weekly or more often was associated with increased likelihood of relapse to ongoing opioid use compared with less than weekly or no stimulant use (adjusted odds ratio = 2.30, CI = 1.05-5.39, P = 0.044). People initiated on medication for opioid use disorder who subsequently use stimulants appear to be more likely to return to and continue using non-prescribed opioids compared with those without stimulant use. The association appears to be stronger among patients who initiate buprenorphine compared with those who initiate extended-release naltrexone.

Medication for opioid use disorder (MOUD) improves treatment retention and reduces illicit opioid use. A-CHESS is an evidence-based smartphone intervention shown to improve addiction-related behaviors. The authors tested the efficacy of MOUD alone versus MOUD plus A-CHESS to determine whether the combination further improved outcomes. In an unblinded parallel-group randomized controlled trial, 414 participants recruited from outpatient programs were assigned in a 1:1 ratio to receive either MOUD alone or MOUD+A-CHESS for 16 months and were followed for an additional 8 months. All participants were on methadone, buprenorphine, or injectable naltrexone. The primary outcome was abstinence from illicit opioid use; secondary outcomes were treatment retention, health services use, other substance use, and quality of life; moderators were MOUD type, gender, withdrawal symptom severity, pain severity, and loneliness. Data sources were surveys comprising multiple validated scales, as well as urine screens, every 4 months. There was no difference in abstinence between participants in the MOUD+A-CHESS and MOUD-alone arms across time (odds ratio=1.10, 95% CI=0.90-1.33). However, abstinence was moderated by withdrawal symptom severity (odds ratio=0.95, 95% CI=0.91-1.00) and MOUD type (odds ratio=0.57, 95% CI=0.34-0.97). Among participants without withdrawal symptoms, abstinence rates were higher over time for those in the MOUD+A-CHESS arm than for those in the MOUD-alone arm (odds ratio=1.30, 95% CI=1.01-1.67). Among participants taking methadone, those in the MOUD+A-CHESS arm were more likely to be abstinent over time (b=0.28, SE=0.09) than those in the MOUD-alone arm (b=0.06, SE=0.08), although the two groups did not differ significantly from each other(∆b=0.22, SE=0.11). MOUD+A-CHESS was also associated with greater meeting attendance (odds ratio=1.25, 95% CI=1.05-1.49) and decreased emergency department and urgent care use (odds ratio=0.88, 95% CI=0.78-0.99). Overall, MOUD+A-CHESS did not improve abstinence relative to MOUD alone. However, MOUD+A-CHESS may provide benefits for subsets of patients and may impact treatment utilization.

This article is one of a series coordinated by APA’s Council on Consultation-Liaison Psychiatry and the Academy of Consultation-Liaison Psychiatry.The prevalence, morbidity, mortality, and costs of opioid use disorder have dramatically increased over the past 20 years. While there are several effective and evidence-based medications for opioid use disorder (MOUD), less than 20% of Americans with opioid use disorder receive MOUD. The inpatient general hospital setting represents a critical point of access to MOUD, given the significant medical comorbidities of patients with opioid use disorder and the increased time to engage patients in treatment, better monitoring capabilities, and opportunities to reduce the monetary impact of the disorder on the health care system.Psychiatrists are an integral part of the hospital treatment team. However, they are often excluded for many reasons, including stigma toward opioid use disorder, lack of consultation-liaison (C-L) psychiatry services, and discomfort with managing opioid use disorder.To help address this care gap, APA’s Council on C-L Psychiatry, in collaboration with the Council on Addiction Psychiatry, convened a multispecialty expert workgroup to prepare a resource document related to the medication treatment of patients with opioid use disorder. The workgroup discussed several barriers to medication treatment and factors limiting the involvement of psychiatrists in the treatment of opioid and other substance use disorders in the inpatient hospital setting. Among the barriers they identified were stigma associated with substance use disorders (SUD) and a knowledge gap among psychiatrists regarding SUD treatment. The workgroup then created a resource document that seeks to address these barriers and guide general psychiatrists.The document includes an overview of OUD and its management in adults, explores the pharmacology of MOUD, describes barriers to care and specialty-specific concerns, and provides approaches to reducing stigma. The resource document also compares current medications to treat patients with opioid use disorder (naltrexone, buprenorphine, and methadone), walks psychiatrists through the medications’ initiation and titration in the general hospital setting, and provides recommendations on how to transition patients taking these medications from inpatient to outpatient settings.The resource guide is designed to educate and empower psychiatrists to take a larger role in MOUD in the general hospital setting to save more lives at reduced cost. Psychiatrists are in a strong position to oversee the use of MOUD in hospital settings and are best equipped to lead MOUD treatment and reduce stigma, given our relative expertise in the area of SUDs, comorbid psychiatric illnesses, and harm reduction strategies. As such, it is important that psychiatrists stay up to date on evidence-based MOUD and work with other specialties to promote psychiatric involvement in the care of those with opioid use disorder in the general hospital setting. ■Resource Document on the Treatment of Opioid Use Disorder in the General HospitalAbhisek Chandan Khandai, M.D., is a consultation-liaison psychiatry attending at UT Southwestern Medical Center and a member of APA’s Committee on Consultation-Liaison Psychiatry.Josie Francois, M.D., is a first-year psychiatry resident at Brigham and Women’s Hospital.

Medication for opioid use disorder (MOUD) is the criterion standard treatment for opioid use disorder (OUD), but nationally representative studies of MOUD use in the US are lacking. To estimate MOUD use rates and identify associations between MOUD and individual characteristics among people who may have needed treatment for OUD. Cross-sectional, nationally representative study using the 2019 National Survey on Drug Use and Health in the US. Participants included community-based, noninstitutionalized adolescent and adult respondents identified as individuals who may benefit from MOUD, defined as (1) meeting criteria for a past-year OUD, (2) reporting past-year MOUD use, or (3) receiving past-year specialty treatment for opioid use in the last or current treatment episode. The main outcomes were treatment with MOUD compared with non-MOUD services and no treatment. Associations with sociodemographic characteristics (eg, age, race and ethnicity, sex, income, and urbanicity); substance use disorders; and past-year health care or criminal legal system contacts were analyzed. Multinomial logistic regression was used to compare characteristics of people receiving MOUD with those receiving non-MOUD services or no treatment. Models accounted for predisposing, enabling, and need characteristics. In the weighted sample of 2 206 169 people who may have needed OUD treatment (55.5% male; 8.0% Hispanic; 9.9% non-Hispanic Black; 74.6% non-Hispanic White; and 7.5% categorized as non-Hispanic other, with other including 2.7% Asian, 0.9% Native American or Alaska Native, 0.2% Native Hawaiian or Pacific Islander, and 3.8% multiracial), 55.1% were aged 35 years or older, 53.7% were publicly insured, 52.2% lived in a large metropolitan area, 56.8% had past-year prescription OUD, and 80.0% had 1 or more co-occurring substance use disorders (percentages are weighted). Only 27.8% of people needing OUD treatment received MOUD in the past year. Notably, no adolescents (aged 12-17 years) and only 13.2% of adults 50 years and older reported past-year MOUD use. Among adults, the likelihood of past-year MOUD receipt vs no treatment was lower for people aged 50 years and older vs 18 to 25 years (adjusted relative risk ratio [aRRR], 0.14; 95% CI, 0.05-0.41) or with middle or higher income (eg, $50 000-$74 999 vs $0-$19 999; aRRR, 0.18; 95% CI, 0.07-0.44). Compared with receiving non-MOUD services, receipt of MOUD was more likely among adults with at least some college (vs high school or less; aRRR, 2.94; 95% CI, 1.33-6.51) and less likely in small metropolitan areas (vs large metropolitan areas, aRRR, 0.41; 95% CI, 0.19-0.93). While contacts with the health care system (85.0%) and criminal legal system (60.5%) were common, most people encountering these systems did not report receiving MOUD (29.5% and 39.1%, respectively). In this cross-sectional study, MOUD uptake was low among people who could have benefited from treatment, especially adolescents and older adults. The high prevalence of health care and criminal legal system contacts suggests that there are critical gaps in care delivery or linkage and that cross-system integrated interventions are warranted.

Stigma is described as highly relevant to the treatment context for opioid use disorder (OUD) partly because it is known to influence providers' treatment decisions and care provision. However, further study is needed to directly test the salience of stigmatizing views for healthcare decision-making among providers, and particularly those including medication for opioid use disorder (MOUD). This study assessed whether stigma toward illicit opioid use was associated with a willingness to provide or refer patients for MOUD treatment among a sample of healthcare providers. It also evaluated variation in stigmatizing views as a function of familiarity with OUD and MOUD and provider type. Structural equation modeling was utilized to evaluate the antecedents and healthcare decision-making consequences associated with stigma based on survey data from a sample of 144 clinicians participating in a buprenorphine waiver training program (30% female). Providers who have less familiarity with OUD and MOUD and those who are medical students or residents are significantly more likely to endorse stigmatizing views of illicit opioid use. In turn, greater stigma is significantly associated with a lesser willingness to provide treatment or refer patients to MOUD treatment. Further consideration of stigma is recommended in future research to improve clinical practice and increase the implementation of MOUD treatment.

Risks of returning to opioid use at treatment entry and early in opioid use disorder treatment: Role of non-opioid substances

Background: In Colombia, the rapid rise of illicit opioid use has become a major public health concern. Medications for opioid use disorder (MOUD) are well established and effective. However, access to MOUD remains suboptimal in this country. This paper aims to understand barriers to accessing MOUD in Colombia to inform the integration of this treatment modality in health systems. Methods: This study is a cross-sectional survey among persons with opioid use disorder (OUD) not enrolled in MMT in four Colombian cities with high known OUD prevalence. Survey domains consisted of the Barriers to Treatment Inventory, attitudes pertaining to MOUD treatments, and perceptions regarding interventions to ease access to Methadone. Results: A total of 84 subjects completed the survey. The most commonly endorsed barriers were related to admission difficulties, including concerns with “too many steps to get into treatment” (84.3%), experiencing withdrawal symptoms (78.1%), being placed on waiting lists (48.2%), and cost (44.6%). Nearly all participants were receptive to Methadone dispensation in primary care (96.4%) or mobile vans (91.6%). Conclusions: Findings from this study highlight persistent barriers to linking with MOUD among adults with OUD in Colombia requiring increased outpatient treatment programs, flexible methadone dosing, and administrative and financial support for patients.

PurposeThis study aims to examine the relationship between medication for opioid use disorder (MOUD) among pregnant individuals, referral source, mental health, political affiliation and substance use policies in all 50 states in the USA.Design/methodology/approachThis study describes MOUD receipt among pregnant people with an opioid use disorder (OUD) in 2018. The authors explored sociodemographic differences in MOUD receipt, referrals and co-occurring mental health disorders. The authors included a comparison of MOUD receipt among states that have varying substance use policies and examined the impact of these policies and the political affiliation on MOUD. The authors used multilevel binary logistic regression to examine effects of individual and state-level characteristics on MOUD.FindingsAmong 8,790 pregnant admissions with OUD, the majority who received MOUD occurred in the Northeast region (71.52%), and 14.99% were referred by the criminal justice system (n = 1,318). Of those who were self-referred, 66.39% received MOUD, while only 30.8% of referrals from the criminal justice system received MOUD. Those referred from the criminal justice system or who had a co-occurring mental health disorder were least likely to receive MOUD. The multilevel model showed that while policies were not a significant predictor, a state’s political affiliation was a significant predictor of MOUD.Research limitations/implicationsThe study has some methodological limitations; a state-level analysis, even when considering the individual factors, may not provide sufficient description of community-level or other social factors that may influence MOUD receipt. This study adds to the growing literature on the ineffectiveness of prenatal substance use policies designed specifically to increase the use of MOUD. If such policies are consistently assessed as not contributing to substantial increase in MOUD among pregnant women over time, it is imperative to investigate potential mechanisms in these policies that may not facilitate MOUD access the way they are intended to.Practical implicationsFindings from this study aid in understanding the impact that a political affiliation may have on treatment access; states that leaned more Democratic were more likely to have higher rates of MOUD, and this finding can lead to research that focuses on how and why this contributes to greater treatment utilization. This study provides estimates of underutilization at a state level and the mechanisms that act as barriers, which is a stronger assessment of how state-specific policies and practices are performing in addressing prenatal substance use and a necessary step in implementing changes that can improve the links between pregnant women and MOUD.Originality/valueTo the best of the authors’ knowledge, this is the first study to explore individual-level factors that include mental health and referral sources to treatment that lead to MOUD use in the context of state-level policy and political environments. Most studies estimate national-level rates of treatment use only, which can be useful, but what is necessary is to understand what mechanisms are at work that vary by state. This study also found that while substance use policies were designed to increase MOUD for pregnant women, this was not as prominent a predictor as other factors, like mental health, being referred from the criminal justice system, and living in a state with more Democratic-leaning affiliations.
