Geographic variation in availability of opioid treatment programs across U.S. communities

Methadone for Opioid Use Disorder (OUD) treatment is only dispensed at Opioid Treatment Programs (OTPs). Little is known about the geographic variation in OTP availability and community characteristics associated with the availability across smaller geographic communities in the U.S. To (1) describe geographic distribution of OTPs and (2) examine OTP availability by community characteristics in the contiguous U.S. at Zip Code Area Tabulation (ZCTA) level. Logistic regression was used to examine community characteristics associated with OTP availability (N = 30,367). Chi-square and t-tests were conducted to examine statistically significant differences in OTP availability. Maps and descriptive statistics were used to examine geographic variation in OTP availability. Only 5% (1,417) of ZCTAs had at least one OTP for a total of 1,682 OTPs. Rural ZCTAs had 50% lower odds of having an OTP compared to urban ZCTAs [AOR 0.5; (95% CI: 0.41-0.60)]. ZCTAs in the lowest income quartile had higher odds of having an OTP compared to ZCTAs in the highest income quartile [AOR 3.4; (95% CI: 2.71-4.18)]. Further, ZCTAs with OTPs had a higher proportion of minority residents [Black: 17.5% vs. 7.2%; Hispanic: 19.2% vs. 9%] and a lower proportion of White residents [55.1% vs. 78.2%]. Nationally, OTPs are extremely scarce with notable regional and urban-rural disparities. Potential solutions to address these disparities are discussed.

Implementation and analysis of a multifaceted intervention for alcohol use disorder from a single academic urban emergency department

BACKGROUND

From 2006 to 2014, alcohol-related visits to the emergency department (ED) increased by 76% in the United States, highlighting the need for improved ED-driven interventions addressing alcohol use disorder (AUD). Naltrexone is an FDA-approved medication for AUD shown to decrease craving and self-administration of alcohol. While oral naltrexone and extended-release naltrexone have been long utilized in primary care and inpatient hospital settings, the use of naltrexone in the ED is limited.

METHODS

This study implemented and analyzed a multifaceted intervention regarding ED naltrexone prescribing at a large safety net, academic, urban hospital. A baseline assessment of preintervention conditions and perspectives on naltrexone prescribing was conducted through a chart review and standardized interviews with ED providers, respectively. The interview results guided design of interventions that addressed identified barriers. These included provider education, prescribing aids, and zero-cost naltrexone tablets supplied by the ED pharmacy to patients upon discharge.

RESULTS

Between September 1, 2019, and August 31, 2020, of 753 unique patients who had a primary diagnosis or chief complaint containing the word "alcohol," only five (0.66%) were prescribed naltrexone. ED providers identified lack of training regarding naltrexone, lack of a prescribing protocol, and limited patient and provider education materials as barriers to prescribing naltrexone. Following the intervention, among 278 eligible patients, 11 oral naltrexone prescriptions were written (3.96%) between April 13, 2021, and August 1, 2021. This represents a sixfold increase over the preintervention period.

CONCLUSIONS

An intervention to increase ED oral naltrexone prescriptions for AUD was successfully implemented, addressing lack of provider education, lack of prescribing resources, and patient barriers to accessing prescribed medications. Longer-term follow-up is needed to assess the efficacy and sustainability of these interventions. Nevertheless, ED clinicians are well positioned to initiate naltrexone prescriptions for patients presenting with AUD.

The Lived Experiences of Pregnant and Parenting Women in Recovery Toward Medication Treatment for Opioid Use Disorder

BACKGROUND

Maternal misuse of prescription opioids and illicit drugs such as, heroin and non-pharmaceutical fentanyl analogs has increased in the last 2 decades and one in 5 women reported misuse of opioids. Medications for opioid use disorder (MOUD) are recommended for treating pregnant women with opioid use disorder (OUD). MOUD is effective in reducing cravings and negative outcomes, yet treatment is underutilized and varies in integration and intensity of resources across health systems. Exploring perceptions of MOUD delivery among pregnant/parenting women promises to uncover and address the underlying challenges to treatment, a perspective that may be different for providers and stakeholders. Therefore, our main purpose is to elicit patients' experiences and perceptions of MOUD, associated access to treatment, and availability of supportive resources during pregnancy/postpartum to inform OUD treatment.

METHODS

Through a qualitative research approach we gathered data from individual interviews/focus group discussions for this pilot study. Pregnant and postpartum parenting women (n = 17) responded to questions related to perceptions of MOUD, access to treatment, and availability of social and psychosocial resources. Data were collected, transcribed, and coded (by consensus) and emerging themes were analyzed using grounded theory methodology.

RESULTS

Emerging themes revealed positive uptake and perceptions of MOUD, continuing gaps in knowledge, negative impact of stigmatization, and limited access to programs and resources. Supportive relationships from family, peers, healthcare providers and child welfare staff, and co-located services were perceived as positive motivators to recovery.

CONCLUSIONS

Through the unique lenses of women with lived experience, this study revealed several themes that can be transformative for women. Overall perceptions of MOUD were positive and likely to facilitate uptake and promote positive recovery outcomes. Bridging knowledge gaps will reduce anxieties, fears about neonatal opioid withdrawal syndrome and adverse maternal outcomes. Additionally, a deeper understanding of stigmatization and relationships can inform an integrated patient-centered approach to OUD treatment.

Herba Epimedii and Increased Opioid Cravings While on Buprenorphine: A Case Report

Herba Epimedii, commonly known as yin yang huo, inyokaku, and horny goat weed, is a traditional Chinese herbal medicine utilized for treating osteoporosis and enhancing libido. Studies conducted in vitro have demonstrated that Herba Epimedii interacts with the enzyme cytochrome P450 3A4 (CYP3A4). This interaction poses a potential risk for drug-drug interactions, particularly with medications metabolized by CYP3A4, such as buprenorphine. This paper presents a case of a patient experiencing exacerbated opioid cravings following the initiation of Herba Epimedii. This is the first reported case supporting this interaction, emphasizing the necessity of screening for alternative medicines in patients undergoing medication-assisted treatments for opioid use disorder.

Comorbidity of Lifetime History of Abuse and Trauma With Opioid Use Disorder: Implications for Nursing Assessment and Care

BACKGROUND

Opioid use disorder (OUD) is a public health crisis and is challenging to treat. Previous research has shown correlations between OUD, abuse/trauma, and chronic pain.

AIMS

The purpose of this study was to investigate history of lifetime sexual, physical, and/or emotional abuse among participants in a medication-assisted treatment (MAT) program for OUD, and to investigate associations between abuse history and chronic pain.

METHODS

This is a secondary analysis of intake data from a 2-year, nonexperimental cohort treatment program of patients with OUD in rural Colorado. De-identified data were provided by 476 adult MAT patients using the Adult Addiction Severity Index (ASI-6). The ASI-6 includes three yes/no questions about history of abuse (emotional, physical, and sexual), with separate scoring for "past 30 days" and "lifetime" abuse.

RESULTS

Lifetime history among MAT program for OUD patients was 23% for sexual abuse, 43% for physical abuse, and 58% for emotional abuse. History of physical abuse was significantly associated with having a chronic pain diagnosis, χ2 = 4.49, p = .03, and also with higher reported pain levels, t(460) = 2.71, p = .007.

CONCLUSION

Lifetime history of physical abuse was associated with OUD and chronic pain, yet standard pain assessments do not assess these factors. In health care settings, the implementation of standardized trauma-informed screening tools, prompt recognition of abuse/trauma history, and adjunct psychological interventions may reduce stigma, reduce opioid use escalation, and help patients overcome OUD.

Prior authorization restrictions on medications for opioid use disorder: trends in state laws from 2005 to 2019

RESEARCH OBJECTIVE

Medications for opioid use disorder (MOUDs) - including methadone, buprenorphine, and naltrexone - are the most effective treatments for opioid use disorder (OUD). Historically, insurers have required prior authorization for MOUD, but prior authorization is often reported as a key barrier to MOUD prescribing. Some states have passed laws prohibiting MOUD prior authorization requirements. We sought to identify the frequency of MOUD prior authorization prohibitions in state laws and to categorize types of prohibitions.

METHODS

We searched for regulations and statutes present in all U.S. states and Washington DC between 2005 and 2019 using MOUD-related terms in Westlaw legal software. In qualitative software, we coded laws discussing MOUD prior authorization using template analysis - a mixed deductive/inductive approach. Finally, we used coded laws to identify frequencies of states with prior authorization prohibitions, including changes over time.

RESULTS

No states had laws prohibiting MOUD prior authorization between 2005 and 2015, with the first prohibition appearing in 2016. By 2019, fifteen states had MOUD prior authorization prohibitions. States varied significantly in their approach to prohibiting MOUD prior authorization. In 2019, it was more common for states to have MOUD prior authorization prohibitions applying to all insurers (n = 10 states) than to only Medicaid (n = 7 states) or only non-Medicaid insurers (n = 1 state). In 2019, general prior authorization prohibitions (n = 10 states) were more common than prohibitions only applicable to medications on the formulary, prohibitions only applicable to medications on the preferred drug list, prohibitions only applicable during the first 5 days of treatment, and prohibitions only applicable during the first 30 days of treatment.

CONCLUSIONS

The number of states with an MOUD prior authorization law prohibition increased in recent years. Such laws could help expand access to life-saving OUD treatments by making it easier for clinicians to prescribe MOUD.KEY MESSAGESNo states had MOUD prior authorization prohibitions between 2005 and 2015 in state statutes or regulations, and only one state had such a prohibition in 2016.By 2019, fifteen states had an MOUD prior authorization prohibition law.States varied significantly in their approach to prohibiting MOUD prior authorization, including with respect to the insurer type, duration of the prohibition, and applicable medication.

Waiting times disparities for medication-assisted therapy among opioid use disorder treatment population in the United States

Opioid use disorder (OUD) treatment has been described as beneficial in reducing the burden of OUD and its related complications. Thus far, there is a paucity of literature on the time-to-treatment differences from the period of seeking treatment to when the patient starts treatment. Hence, it is deemed a form of barrier to the accessibility of OUD treatment programs. We aim to study the relationship between accessibility for medication-assisted treatment and the disparity concerning days waiting to enter OUD treatment. The treatment episode data set (TEDS) was utilized for this study. The full sample of 2018 TEDS-D (N = 382,547) is representative of OUD patients that utilized SUD treatment facilities within the 50 states of the United States. Univariate and multivariable logistic analysis of the independent variables, and other covariates with the dependent variables were explored to estimate the adjusted odds ratio relationship. Medication-assisted opioid therapy use among respondents was significantly different with waiting 1-7 days [AOR = 1.321 (95% CI = 1.248-1.400)] and >7 days [AOR = 0.729 (95% CI = 0.665-0.799)] to enter OUD treatment compared to waiting for less than a day. Among adults seeking OUD treatment admissions, our study showed that waiting times vary with MAT use as there was early entry compared to >1week wait time. Similarly, significant associations were reported across different sociodemographic attributes except for biological sex.

Association between body mass index and treatment completion in extended-release naltrexone-treated patients with opioid dependence

Background

Excessive consumption of opioids is associated with impaired metabolic function including increased body mass index (BMI). Opioid antagonist naltrexone (NTX) is an effective treatment for opioid use disorder (OUD) that has the potential to mitigate such metabolic disturbances. Understanding the relationship between treatment adherence and BMI in NTX-treated OUD patients may provide valuable insights into optimizing clinical outcomes.

Methods

Patients with opioid dependence were offered up to three monthly injections of extended-release (XR) NTX. Treatment completers (n = 41) were defined as those who had received all three XR-NTX injections, and non-completers (n = 20) as those missing at least one injection. Logistic regression was performed to examine the association between pre-treatment BMI and treatment completion.

Results

BMI was positively associated with treatment completion. This association remained significant after adjusting for potentially confounding variables.

Conclusion

Our findings suggest that baseline BMI may serve as a potential predictor of XR-NTX treatment adherence in patients with OUD and could help healthcare providers and policy makers alike in developing strategies to improve retention and tailor interventions for specific patient subgroups.

The Lived Experience of Medication for Opioid Use Disorder: Qualitative Metasynthesis

PURPOSE OF THE STUDY

Buprenorphine and methadone, when used as maintenance therapy in opioid use disorder (OUD), can significantly reduce the risk of death after an opioid overdose. Despite the many benefits, medication for OUD (MOUD) remains controversial and underutilized. The aim of this study was to (a) identify studies that explicate the lived experience of MOUD, (b) conduct a methodologically sound critical quality assessment, (c) conduct a metasynthesis of identified qualitative studies, and (d) analyze the results through the lenses of critical social justice, feminist standpoint, and social theories to inform a more culturally responsive, effective, and holistic approach to treatment to increase the utilization of and receptivity to MOUD in the treatment of OUDs.

DESIGN AND METHODS

Metasynthesis is the deliberate process of synthesizing data from multiple qualitative studies to create a new interpretation of previously published research. Our metasynthesis focused on forming a new interpretation of the lived experience of MOUD. Of the 292 studies identified, eight met inclusion criteria. The overall quality of the studies was variable. The study population included adults aged ≥ 18 years with OUD or dependency.

RESULTS

Metasynthesis produced three overarching themes: (a) The duplexity of MOUD creates ambivalence in how a person experiences MOUD; (b) the structure of treatment and systemic influences matter, and (c) MOUD as a stepping-stone with multiple meanings in recovery.

IMPLICATIONS

Understanding experiential dualities allows professionals to see from other perspectives and can inform interventions and treatment structures as well as serve as a backdrop for social change. The synthesized new meaning of MOUD was an ambivalent experience influenced by intersectionality.

A Bayesian Spatio-temporal Model to Optimize Allocation of Buprenorphine in North Carolina

The opioid epidemic is an ongoing public health crisis. In North Carolina, overdose deaths due to illicit opioid overdose have sharply increased over the last 5-7 years. Buprenorphine is a U.S. Food and Drug Administration approved medication for treatment of opioid use disorder and is obtained by prescription. Prior to January 2023, providers had to obtain a waiver and were limited in the number of patients that they could prescribe buprenorphine. Thus, identifying counties where increasing buprenorphine would yield the greatest overall reduction in overdose death can help policymakers target certain geographical regions to inform an effective public health response. We propose a Bayesian spatiotemporal model that relates yearly, county-level changes in illicit opioid overdose death rates to changes in buprenorphine prescriptions. We use our model to forecast the statewide count and rate of illicit opioid overdose deaths in future years, and we use nonlinear constrained optimization to identify the optimal buprenorphine increase in each county under a set of constraints on available resources. Our model estimates a negative relationship between death rate and increasing buprenorphine after accounting for other covariates, and our identified optimal single-year allocation strategy is estimated to reduce opioid overdose deaths by over 5.

Body Mass Index Trends among a Cohort of Subjects Enrolled in Medication-Assisted Treatment Programmes for Opioid Use Disorder: Racial/Ethnic, Gender, and Age Differences

Introduction

Opioid use disorder (OUD) and obesity are two pressing public health concerns in the United States (US). However, the relationship between these two epidemics has not been well-studied. Our study aims to describe the prevalence rates of obesity in individuals with OUD from a cohort study and compare that to the expected prevalence that would be observed based upon New Jersey state and US population survey data. Additionally, we sought to study whether Body Mass Index (BMI) distribution in this cohort varied by race/ethnicity, gender, and age.

Methods

Our subjects (N=151) are part of a drug user cohort study of persons enrolled in medication-assisted treatment (MAT) programmes in New Jersey. Using the New Jersey Behavioral Risk Factor Survey (NJBRFS) and the National Health Interview Survey (NHIS), we generated expected BMI distributions based on race/ethnicity, age, and sex. Expected rates were compared to observed BMI. Standardized prevalence ratios were calculated, and 95% confidence intervals were constructed.

Results

Among females, obesity was more prevalent in those with OUD than in the general US population. Among persons ≤50 years old, overweight and obesity were more prevalent in those with OUD than in NJBRFS. Persons who did not inject drugs were more likely to be overweight. The prevalence of underweight was significantly higher among Black non-Hispanic minorities, males, older subjects (aged 66-85), and persons who inject drugs.

Conclusion

In our study, the trends in BMI vary based on race/ethnicity, gender and age in these patients with OUD. These varying trends highlight the need for tailored screening and prevention strategies. Primary care providers should be aware that their patients with OUD have multiple health problems that need to be addressed beyond their OUD condition itself. Providers are in a pivotal role to screen and implement interventions to improve their health outcomes.

Lessening the Impact of Opioid Misuse at a Federally Qualified Health Center in New York: Outcomes of an Integrated Workforce Training Program

The COVID-19 pandemic has placed an unprecedented burden on patients, health care providers, and communities and has been particularly challenging for medically underserved populations impacted by the social determinants of health, as well as people with co-occurring mental health and substance use risks. This case study examines outcomes and lessons learned from a multisite low-threshold medication-assisted treatment (MAT) program at a federally qualified health center in partnership with a large suburban public university in New York to integrate and train Health Resources & Services Administration Behavioral Health Workforce Education and Training-funded graduate student trainees in social work and nursing in screening, brief intervention, and referral to treatment and patient care coordination, including social determinants of health and medical and behavioral comorbidities. The MAT program for the treatment of opioid use disorder has a low threshold for entry that is accessible and affordable, reduces barriers to care, and uses a harm reduction approach. Outcome data showed an average 70% retention rate in the MAT program and reductions in substance use. And, while more than 73% of patients reported being somewhat or definitely impacted by the pandemic, most patients endorsed the effectiveness of telemedicine and telebehavioral health, such that 86% indicated the pandemic did not affect the quality of their health care. The main implementation lessons learned were the importance of increasing the capacity of primary care and health care centers to deliver integrated care, using cross-disciplinary practicum experiences to enhance trainee competencies, and addressing the social determinants of health among populations with social vulnerabilities and chronic medical conditions.

Assessing Sustainability of State-Led Action Plans for the Opioid Use Disorder, Maternal Outcomes, and Neonatal Abstinence Syndrome Initiative Learning Community, 2018-2021

Objective(s): The opioid crisis affects the health and health care of pregnant and postpartum people and infants prenatally exposed to substances. A Learning Community (LC) among 15 states was implemented to improve services for these populations. States drafted action plans with goals, strategies, and activities. Materials and Methods: Qualitative data from action plans were analyzed to assess how reported activities aligned with focus areas each year. Year 2 focus areas were compared with year 1 to identify shifts or expansion of activities. States self-assessed progress at the LC closing meeting, reported goal completion, barriers and facilitators affecting goal completion, and sustainment strategies. Results: In year 2, many states included activities focused on access to and coordination of quality services (13 of 15 states) and provider awareness and training (11 of 15). Among 12 states participating in both years of the LC, 11 expanded activities to include at least one additional focus area, adding activities in financing and coverage of services (n = 6); consumer awareness and education (n = 5); or ethical, legal, and social considerations (n = 4). Of the 39 goals developed by states, 54% were completed, and of those not completed, 94% had ongoing activities. Barriers to goal completion included competing priorities and pandemic-related constraints, whereas facilitators involving use of the LC as a forum for information-sharing and leadership-supported goal completion. Sustainability strategies were continued provider training and partnership with Perinatal Quality Collaboratives. Conclusion: State LC participation supported sustainment of activities to improve health and health care for pregnant and postpartum people with opioid use disorder and infants prenatally exposed to substances.

Medication-Assisted Treatment in Problem-solving Courts: A National Survey of State and Local Court Coordinators

Problem-solving courts (PSCs) are a critical part of a societal effort to mitigate the opioid epidemic's devastating consequences. This paper reports on a national survey of PSCs (N = 42 state-wide court coordinators; N = 849 local court coordinators) and examines the structural factors that could explain the likelihood of a local PSC authorizing medication-assisted treatment (MAT) and MAT utilization. Results of the analyses indicate that MAT availability at the county level was a significant predictor of the likelihood of local courts authorizing MAT. The court's location in a Medicaid expansion state was also a significant predictor of local courts allowing buprenorphine and methadone, but not naltrexone. Problem-solving courts are in the early stages of supporting the use of medications, even when funding is available through Medicaid expansion policies. Adoption and use of treatment innovations like MAT are affected by coordinators' perceptions of MAT as well as structural factors such as the availability of the medications in the community and funding resources. The study has important implications for researchers, policymakers, and practitioners.

The development and validation of the pandemic medication-assisted treatment questionnaire for the assessment of pandemic crises impact on medication management and administration for patients with opioid use disorders

Pandemic and the globally applied restriction measures mainly affect vulnerable population groups, such as patients with opioid use disorders. Towards inhibiting SARS-Cov-2 spread, the medication-assisted treatment (MAT) programs follow strategies targeting the reduction of in-person psychosocial interventions and an increase of take-home doses. However, there is no available instrument to examine the impact of such modifications on diverse health aspects of patients under MAT. The aim of this study was to develop and validate the PANdemic Medication-Assisted Treatment Questionnaire (PANMAT/Q) to address the pandemic effect on the management and administration of MAT. In total, 463 patients under ΜΑΤ participated. Our findings indicate that PANMAT/Q has been successfully validated exerting reliability and validity. It can be completed within approximately 5 min, and its implementation in research settings is advocated. PANMAT/Q could serve as a useful tool to identify the needs of patients under MAT being at high risk of relapse and overdose.

The Effects of Opioid Use during Pregnancy on Infant Health and Well-Being

In this study, we estimate the first causal effects of in utero opioid exposure on infant health at birth and child protective services reports. We employ maternal fixed-effects models using linked administrative data capturing 259,723 infants born to 176,224 mothers enrolled in Medicaid between 2010 and 2019. Our preferred specifications suggest that neonatal abstinence syndrome and NICU admission bear strong associations with prenatal opioid exposure, concentrated on illicit and medication assisted treatment (MAT) exposure in the first and third trimesters. We find that prenatal opioid exposure is associated with increased CPS reports, low birth weight, preterm birth, and small for gestational age, though these measures are less sensitive with respect to the timing of exposure. While we detect relatively smaller effects of non-MAT prescription opioid exposure on NAS, NICU admission, low birthweight, these effects are not trivial, suggesting that medical professionals should consider balancing the potential for adverse side effects of infants with the benefits of pain management for pregnant women.

Outcomes of a Quality Improvement Project: Screening for Adverse Childhood Experiences in Medication-Assisted Treatment

BACKGROUND

Adverse childhood experiences (ACEs) are traumatic childhood events that alter biopsychological markers of the human body, causing significant damaging lifelong effects and increasing health risk behavior, including substance use disorder (SUD).

OBJECTIVE

This project evaluated an ACE screening tool in medication-assisted treatment (MAT) patients at a federally qualified healthcare center (FQHC) via a handheld patient tablet.

METHODS

All MAT patients received the 10-question Kaiser Permanente ACE screening tool; 192 patients (N) (98 men and 94 women) completed the ACE screening. Age and gender demographics were collected. Pre- and post-ACE screening behavioral health (BH) referral rates were measured utilizing electronic health record (EHR) reports. After 3 months, post-ACE screening BH referral rates were compared to pre-ACE screening rates from the same 3 months of the previous year.

RESULTS

Post-ACE screening increased BH referrals by 29.76%, a statistically significant finding (z < .00001).

CONCLUSION

Screening for ACEs in MAT clinics is an effective trauma-informed intervention to increase BH referrals.

IMPLICATIONS FOR NURSING

Using technology to incorporate ACE screening in MAT is feasible and provides a deeper understanding of a patient's mental health and trauma history.

Opioid Use Disorder Education for Students and the Future of Opioid Overdose Treatment

Opioid use disorder (OUD) is a major public health concern in the United States. The opioid crisis has taken hundreds of thousands of lives in the past 20 years, and it is predicted to take millions more. With the rising death tolls, it is essential that health care providers are able to use proper tools to treat OUD efficiently and effectively through medication-assisted treatment (MAT), particularly buprenorphine. Despite changes to buprenorphine regulations making it more accessible, clinicians have been slow to use buprenorphine to treat OUD. We believe that training student clinicians in evidence-based MAT and buprenorphine practices will address the training and competence barriers that hinder clinicians from prescribing buprenorphine to treat OUD. Students are in an ideal position to receive and benefit from this training and influence the medical community to better treat OUD.

Review of medication-assisted treatment for opioid use disorder

CONTEXT

The American opioid epidemic has necessitated the search for safe and effective means of treatment for opioid use disorder (OUD). Medication-assisted treatment (MAT) encompasses select medications that are proven effective treatments for OUD. Understanding the mechanisms of action, indications, and implementation of MAT is paramount to increasing its availability to all individuals struggling with opioid addiction.

OBJECTIVES

This review is based on an educational series that aims to educate healthcare providers and ancillary healthcare members on the use of MAT for the treatment of OUD.

METHODS

The database PubMed was utilized to retrieve articles discussing the implementation of MAT. Boolean operators and Medical Subject Headings (MeSHs) were applied including: MAT and primary care, MAT and telehealth, methadone, buprenorphine, naltrexone, MAT and osteopathic, MAT and group therapy, and MAT and COVID-19.

RESULTS

Three medications have been approved for the treatment of OUD: methadone, naltrexone, and buprenorphine. Identifying ways to better treat and manage OUD and to combat stigmatization are paramount to dismantling barriers that have made treatment less accessible. Studies suggest that primary care providers are well positioned to provide MAT to their patients, particularly in rural settings. However, no study has compared outcomes of different MAT models of care, and more research is required to guide future efforts in expanding the role of MAT in primary care settings.

CONCLUSIONS

The coronavirus disease 2019 (COVID-19) pandemic has led to changes in the way MAT care is managed. Patients require a novel point-of-care approach to obtain care. This review will define the components of MAT, consider the impact of MAT in the primary care setting, and identify barriers to effective MAT. Increasing the availability of MAT treatment will allow for greater access to comprehensive treatment and will set the standard for accessibility of novel OUD treatment in the future.

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.

Barriers and Facilitators to DATA Waivered Providers Prescribing Buprenorphine: A Qualitative Analysis Applying the Theory of Planned Behavior

Background: Provider beliefs about the treatment of people with addiction may influence their prescribing behavior. Objective: This study applied the Theory of Planned Behavior (TPB), to identify the salient beliefs of Drug Addiction Treatment Act of 2000 (DATA 2000) waivered providers, concerning prescribing buprenorphine to patients with Opioid Use Disorder (OUD). Methods: Texas buprenorphine providers participated in one of four online focus group discussions conducted in fall 2019. The focus group discussion were audio recorded and the total length was between 60-90 minutes. Thematic analysis was conducted to identify emerging themes and to categorize the behavioral, normative, and control beliefs related to buprenorphine prescribing. Results: Of the 14 total participants, 57% of the participants were male and annually treated between zero to sixty patients with buprenorphine. The codes generated were represented in thematic maps, specifying the positive or negative aspects of buprenorphine prescribing. Results indicate that providers' primary motivation to prescribe buprenorphine was, implementation of a whole-patient approach through collaboration with behavioral health providers, in the provision of medications for opioid use disorder (MOUD). Providers primary normative belief was the recognition of key members of the medical community and patients' families and friends as influential groups. Providers' control beliefs focused on their ability to use buprenorphine in different practice settings. Conclusion: These results indicate that buprenorphine access may be expanded by increasing support for DATA waivered providers from other parts of the healthcare system such as behavioral health providers and pharmacists. Implications for clinical practice and future research will be discussed.

Suboxone: History, controversy, and open questions

There are more than 200 opioid overdose deaths each day in the US. In combating this epidemic we look to available treatment tools. Here, we find only three medications approved by the Food and Drug Administration (FDA) for the treatment of opioid use disorder. Of the three, buprenorphine is of particular importance due to its reduced overdose potential as a partial opioid agonist. Evidence supports its clinical equivalence to its full agonist cousin methadone, and suggests that it is better slated for long-term treatment of opioid use disorder compared to the non-selective opioid antagonist naltrexone. Buprenorphine is most popularized within Suboxone, a medication which also contains the non-selective opioid antagonist naloxone. The naloxone has no additional effect when the drug is taken as instructed, as it is intended to prevent diversion in those that would attempt to inject the medication. While Suboxone is regarded by some as the future of medical treatment, others have expressed concerns. This review aims to explore the history, controversy, and open questions that surround buprenorphine and its most prescribed variation, Suboxone. These include its pharmacological, legislative, and social history, alternative indications, efficacy as a treatment of opioid use disorder, and more. Armed with this information, the reader will have a more in-depth and holistic understanding of the medication's place in their community.

Buprenorphine Dosage and Urine Quantitative Buprenorphine, Norbuprenorphine, and Creatinine Levels in an Office-Based Opioid Treatment Program

BACKGROUND

Treatment progress is routinely monitored by urine testing in patients with opioid use disorder (OUD) undergoing buprenorphine medication-assisted treatment (MAT). However, interpretation of urine test results could be challenging. This retrospective study aims to examine the results of quantitative buprenorphine, norbuprenorphine, and creatinine levels in urine testing in relation to sublingual buprenorphine dosage to facilitate an accurate interpretation of urine testing results.

METHODS

We reviewed the medical charts of 41 consecutive patients, who were residing in halfway houses where their medication intake was closely monitored and who had enrolled in an office-based MAT program at an urban clinic between July 2018 and June 2019. The patients' urine testing results were reviewed, and demographic variables were recorded. We focused on the patients treated with 8-, 12-, or 16-mg/day of buprenorphine, examining their urine buprenorphine, norbuprenorphine, and creatinine levels. Analysis of variance tested the statistical association between the dosage and urine testing results on the norbuprenorphine-to-creatinine ratio.

RESULTS

A total of 240 urine samples from 41 patients were included for this study. The 41 patients received a mean buprenorphine dose of 10.5 ± 3.7 mg/day (range, 4-20 mg/day). Then, this study examined the distribution of the 240 urine samples and then focused on 184 urine samples that came from the 33 patients who were treated with 8-, 12-, and 16-mg/day of buprenorphine, the 3 most common dosages. All of the 184 urine samples had a creatinine level of >20 mg/dL and buprenorphine-to-norbuprenorphine ratio <50:1. The average norbuprenorphine-to-creatinine ratio in the 8 mg/day dosage group was 3.85 ± 2.24 × 10^-4 (n = 66; range, 0.44-11.12). The respective ratios in the 12- and 16-mg dosage groups were 5.64 ± 3.40 × 10^-4 (n = 83; range, 1.55-22.72) and 6.23 ± 4.92 × 10^-4 (n = 35; range, 1.37-27.12). The 3 dosage groups differed significantly in the mean ratios (P < .01), except when the 12- and 16-mg dosage groups were compared (P = .58). The results of this study thus suggest that prescribers should pay attention to the following features: (1) unexpected substance(s) in urine testing, (2) creatinine level under 20 mg/dL, (3) buprenorphine-to-creatinine ratio over 50:1, (4) buprenorphine dosage over 24 mg/day, and (5) norbuprenorphine-to-creatinine ratio consistently under 0.5 × 10^-4 in patients treated with 8 mg/day or 1.5 × 10^-4 in patients treated with 12 mg/day or more.

CONCLUSION

This study suggested parameters for interpreting quantitative urine test results in relation to buprenorphine intake dose in office-based opioid treatment programs.

Eight-hour medication-assisted treatment waiver training for opioid use disorder: integration into medical school curriculum

Background: The opioid epidemic is a growing problem in the USA. Use of medication-assisted treatment (MAT) has been effective in treating patients with opioid use disorders (OUD) and maintaining sobriety; however, there is a significant shortage of physicians formally trained in MAT. Objective: Wayne State University School of Medicine integrated the 8-hour MAT waiver training into its Internal Medicine clerkship curriculum. The objectives of integrating this into the curriculum were to (1) introduce opioid use education during students' Internal Medicine clerkship and (2) assess whether the curriculum prepares students to feel more comfortable evaluating and treating patients with OUD. Design: MAT training specifically for medical students was provided free online by the Providers Clinical Support System (PCSS). All students on the Internal Medicine clerkship were required to complete the training. A 7-question pre-survey and post-survey assessed students' comfort in evaluating and treating OUD. Significant changes were assessed with a paired McNemar Bowker Test. Results: Medical students (n = 141) completed the pre-survey and post-survey. After the MAT training, students' perspective of their clinical knowledge about OUD, familiarity with MAT, and likelihood to utilize MAT for their patients significantly differed, with increased proportions of medical students in agreement across 6 of 7 pre-post survey items (p <.0001). Conclusions: Online MAT waiver training is a low-cost (free) way to introduce MAT education into the undergraduate clinical curriculum. Upon completing of the training, medical students self-reported improvements in their knowledge and attitudes about OUD and the different treatment options. Our hope is that MAT waiver training will allow for graduation of medical students who are ready to care for patients with OUD during residency and as practitioners upon completion of their residency.

Physician-Perceived Barriers to Treating Opioid Use Disorder in the Emergency Department

Objective We aimed to assess physicians' perceptions of barriers to starting medication-assisted treatment (MAT) in the Emergency Department (ED), views of the utility of MAT, and abilities to link patients with opioid use disorder (OUD) to MAT programs in their respective communities. Methods This was a cross-sectional survey study of American emergency medicine (EM) physicians with a self-administered online survey via SurveyMonkey (Survey Monkey, San Mateo, California). The survey was emailed to the Council of Residency Directors in Emergency Medicine (CORD) listserv and HCA Healthcare affiliated EM residency programs' listservs. Attendings and residents of all post-graduate years participated. Questions assessed perceptions of barriers to starting OUD patients on MAT, knowledge of the X-waiver, and knowledge of MAT details. Statistics were performed with JMP software (SAS Institute Inc., Cary, NC) using the two-tailed Z-test for proportions. Results There were 98 responses, with 33% female, 55% resident physicians, and an overall 17% response rate. Residents were more eager to start OUD patients on MAT (71% vs 52%, p=0.04) than attendings but were less familiar with the X-waiver (38% vs 73%, p=0.001) or where community outpatient MAT facilities were (21% vs 43%, p=0.02). Conclusion Barriers in the ED were identified as a shortage of qualified prescribers, the lengthy X-waiver process, and the poor availability of outpatient MAT resources. EM residents showed more willingness to prescribe MAT but lacked a core understanding of the process. This shows an area of improvement for residency training as well as advocacy among attendings.

Get waivered remote: Nationwide, remote DEA-x waiver course in response to COVID-19

Problem

As of 2020, less than 5% of physicians in the United States have a drug enforcement administration-X waiver to prescribe buprenorphine. The coronavirus-2019 pandemic restricted in-person gatherings, including traditional drug enforcement administration-X waiver courses. As a result, in-person conferences have needed to adopt remote formats. Many programs identified a gap between educational delivery and the faculty skills required to deliver content remotely.

Approach

To address the need for high-quality remote learning, Get Waivered designed and implemented a novel experience for clinicians, called Get Waivered Remote. An educational session was live-streamed via Zoom™. To foster interactivity, like in-person didactic conferences, participants were polled to facilitate discussion among presenters, learners, and facilitators during the broadcast

Outcomes

The RE-AIM framework was used for evaluation. Our program had a Reach encompassing 814 users that participated during the live-streamed event; Effectiveness with 73.79% reporting being somewhat familiar or very familiar with the practice of opioid dependency treatment with approved buprenorphine medications; Adoption with 95.15% reporting a favorable experience and 92.23% reporting it was similar or more enjoyable than their usual teaching; Implementation with 450 messages sent by 281 users to engage with presenters and other learners via Zoom chat in real time.

Next steps

Get Waivered Remote provides a proof-of-concept that a broadcast with a concurrent, interactive remote learning platform is feasible, low cost, and simple to execute. Further study is required to assess the ability of our group to maintain this innovation and also to measure its impact on the treatment of opioid use disorder.

Association between Participation in Counseling and Retention in a Buprenorphine-Assisted Treatment Program for People Experiencing Homelessness with Opioid Use Disorder

The opioid epidemic is a public health crisis that disproportionately affects our unsheltered neighbors. Because medication-assisted treatment (MAT) is effective for preventing deaths from drug overdose and retention is associated with better health outcomes, there is a clear need for more research on factors impacting retention in care. This retrospective cohort analysis examines the relationship between attendance in counseling and retention on buprenorphine for three or more months for individuals experiencing homelessness being treated at a Federally Qualified Health Center (FQHC) and Public Health Service Act §330(h) Health Care for the Homeless Program grantee in San Diego County, California. The cohort included 306 adults experiencing homelessness who had at least one prescription for buprenorphine and participated in a MAT program between 2017 and 2019. The sample included 64.4% men, almost exclusively white, and 35% lived in a place not meant for human habitation. Of the sample, 97 patients were retained at 3 months and 209 were not. Results from a logistic regression model showed that counseling appointments were positively associated with retention at three months (OR = 1.57, p < 0.001). Findings from this study inform future MAT program design components for people experiencing homelessness.

A Personalized, Interactive, Cognitive Behavioral Therapy-Based Digital Therapeutic (MODIA) for Adjunctive Treatment of Opioid Use Disorder: Development Study

BACKGROUND

Opioid use disorder (OUD) is characterized by the inability to control opioid use despite attempts to stop use and negative consequences to oneself and others. The burden of opioid misuse and OUD is a national crisis in the United States with substantial public health, social, and economic implications. Although medication-assisted treatment (MAT) has demonstrated efficacy in the management of OUD, access to effective counseling and psychosocial support is a limiting factor and a significant problem for many patients and physicians. Digital therapeutics are an innovative class of interventions that help prevent, manage, or treat diseases by delivering therapy using software programs. These applications can circumvent barriers to uptake, improve treatment adherence, and enable broad delivery of evidence-based management strategies to meet service gaps. However, few digital therapeutics specifically targeting OUD are available, and additional options are needed.

OBJECTIVE

To this end, we describe the development of the novel digital therapeutic MODIA.

METHODS

MODIA was developed by an international, multidisciplinary team that aims to provide effective, accessible, and sustainable management for patients with OUD. Although MODIA is aligned with principles of cognitive behavioral therapy, it was not designed to present any 1 specific treatment and uses a broad range of evidence-based behavior change techniques drawn from cognitive behavioral therapy, mindfulness, acceptance and commitment therapy, and motivational interviewing.

RESULTS

MODIA uses proprietary software that dynamically tailors content to the users' responses. The MODIA program comprises 24 modules or "chats" that patients are instructed to work through independently. Patient responses dictate subsequent content, creating a "simulated dialogue" experience between the patient and program. MODIA also includes brief motivational text messages that are sent regularly to prompt patients to use the program and help them transfer therapeutic techniques into their daily routines. Thus, MODIA offers individuals with OUD a custom-tailored, interactive digital psychotherapy intervention that maximizes the personal relevance and emotional impact of the interaction.

CONCLUSIONS

As part of a clinician-supervised MAT program, MODIA will allow more patients to begin psychotherapy concurrently with opioid maintenance treatment. We expect access to MODIA will improve the OUD management experience and provide sustainable positive outcomes for patients.

Medicolegal Considerations in the Management of Opioid Use Disorder With Buprenorphine in the Correctional Setting

Buprenorphine-based medication-assisted treatment is a long-term strategy for individuals with opioid use disorder (OUD), a condition observed at disproportionate rates among incarcerated populations. Individuals with OUD are also at higher risk of overdose and death upon community reentry, necessitating effective interventions and care modalities targeted at this high-risk population. As support for buprenorphine in correctional health care increases, so do concerns surrounding personal liability for prescribers. This article seeks to identify problematic events related to prescribing buprenorphine to incarcerated individuals, clarify medicolegal implications, and provide recommendations for safe prescribing and administration within this unique setting.

Stigmatization of medications for opioid use disorder in 12-step support groups and participant responses

Background: 12-step groups are the most common approach to managing opioid use disorder (OUD) in the U.S. Medications for OUD (MOUD) are the most effective tool for preventing opioid misuse and relapse. Previous research has identified stigma of MOUD in 12-step groups. Objectives: We sought to identify how MOUD stigma is operationalized in 12-step groups and to identify responses to stigma. Methods: We recruited individuals with both MOUD experience and 12-step group experience from three syringe exchange programs in the U.S. using snowball sampling. We conducted individual telephone semi-structured interviews during 2018 and 2019. We coded data in Dedoose software and conducted thematic analysis using iterative categorization. Results: We recruited 30 individuals meeting our inclusion criteria. The following stigma operationalization methods were identified: prohibiting people using MOUD from speaking at meetings; encouraging shortened duration of MOUD treatment; refusing to sponsor people using MOUD; and refusing to let people using MOUD claim recovery time. Responses to stigma included the following: feeling shame; feeling anger; shopping around for different groups, leaving the group, or forming a new group; not revealing MOUD utilization or only telling a sponsor; speaking out on behalf of MOUD; and using cognitive approaches to avoid stigma internalization. Cognitive approaches included believing that anti-MOUD stigma is contrary to 12-step principles; disregarding statements as inaccurate based on one's experience of MOUD benefits; and accepting that all groups of humans have some ignorant people. Conclusion: Healthcare systems should help address MOUD stigma experienced by patients in 12-step groups, such as by offering non-12-step alternative groups and encouraging MOUD healthcare providers to prepare patients for potential stigma they may face. Some stigma response options, like shopping around for different groups, may not be feasible in rural areas or for participants newer to recovery.

Therapeutic Approaches to Opioid Use Disorder: What is the Current Standard of Care?

Opioid use disorder is a frequent cause of suffering to communities worldwide. Therapeutic approaches to opioid use disorder include screening, appropriate assessment and diagnosis, consideration of level of care, acute management of overdose or withdrawal, treatment with medications, psychotherapeutic approaches, and community support. People who struggle with addiction to opioids often suffer deeply from direct and indirect consequences of use. Subsequently, it is critical that all medical providers understand the appropriate treatment options for opioid use disorder. This paper provides a comprehensive overview of the therapeutic options available for treatment of this chronic disease.

Perceived Ability to Treat Opioid Use Disorder in West Virginia

INTRODUCTION

Medication-assisted treatment (MAT) is an evidence-based therapy for opioid use disorder (OUD) that has not been fully implemented in rural areas due to patient, provider, and logistical barriers. Limited information is available on provider perceptions of barriers to MAT in rural Central Appalachia which has very high rates of OUD compared to the rest the United States.

PURPOSE

Determine perceived barriers for potential prescribers to using MAT, including buprenorphine, as part of treatment for OUD in West Virginia.

METHODS

A 30-question, anonymous survey was sent to physicians, physician assistants and advanced practice registered nurses using an online link. Link was distributed through the WV Medicaid provider list, professional association and institutional contact lists, and social media. Comparisons were made by provider waivered or non-waivered status.

RESULTS

Overall, 84% of waivered providers (n = 77) and only 8% of non-waivered providers (n = 341) indicated ever prescribing a form of MAT for OUD; 73% percent of waivered providers were currently prescribing MAT and accepting new patients with OUD. Only 4% of non-waivered providers were currently prescribing MAT and 21% were currently accepting new patients with OUD. Lack of available mental health and psychosocial support services and concerns about diversion or misuse of medication were the top perceived barriers to implementing MAT programs.

IMPLICATIONS

Implementing strategies to improve access to behavioral health care including telehealth and apps, provider training and addressing stigma around OUD treatment were identified as priorities that would help increase providers' willingness to prescribe medications for OUD treatment.

Covid19 impact screening of patients undergoing medication treatment for opioid use disorder

BACKGROUND

Populations with addiction are considered at-risk for both medical and financial effects of the COVID19 outbreak. Patients receiving medication treatment for opioid use disorder (MOUD) were screened to assess need, vulnerability factors and potential clinical impact of the pandemic for referral and allocation of resources. Methods: A 31-item quality improvement survey of COVID19-related factors (e.g. engagement in social distancing, food and financial security) and clinical benchmarks of anxiety, craving, and treatment response was administered between March 24 and April 29, 2020. Anonymized data were compiled for study. Frequencies and means were evaluated for gender, age and financial effects on anxiety and craving ratings. Results: A total of 200 (N = 117 male; N = 80 female; N = 1 transgender) patients (age 42 ± 13 years) were screened. Medical risk factors known to predict severe COVID19 reactions reported in 33% of patients did not contribute significantly to distress. While 95% of patients reported stable food and housing, personal financial and employment instability reported in 40% of patients was associated with significantly increased anxiety and craving rating, particularly for women. Conclusions: Financial ramifications of the COVID19 pandemic were the most salient concerns reported by patients engaged in MOUD in the early phases of the outbreak, particularly for women.

Healthcare Access and Utilization Among Persons Who Inject Drugs in Medicaid Expansion and Nonexpansion States: 22 United States Cities, 2018

BACKGROUND

Medicaid expansion under the Affordable Care Act increased insurance coverage, access to healthcare, and substance use disorder treatment, for many Americans. We assessed differences in healthcare access and utilization among persons who inject drugs (PWID) by state Medicaid expansion status.

METHODS

In 2018, PWID were interviewed in 22 US cities for National HIV Behavioral Surveillance. We analyzed data from PWID aged 18-64 years who reported illicit use of opioids (n = 9957) in the past 12 months. Poisson regression models with robust standard errors were used to estimate adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs) were used to examine differences by Medicaid expansion status in indicators of healthcare access and utilization.

RESULTS

Persons who inject drugs in Medicaid expansion states were more likely to have insurance (87% vs 36%; aPR, 2.3; 95% CI, 2.0-2.6), a usual source of healthcare (53% vs 34%; aPR, 1.5; 95% CI, 1.3-1.9), and have used medication-assisted treatment (61% vs 36%; aPR, 1.4; 95% CI, 1.1-1.7), and they were less likely to have an unmet need for care (21% vs 39%; aPR, 0.6; 95% CI, 0.4-0.7) than those in nonexpansion states.

CONCLUSIONS

Low insurance coverage, healthcare access, and medication-assisted treatment utilization among PWID in some areas could hinder efforts to end the intertwined human immunodeficiency virus and opioid overdose epidemics.

Assessment of the impact of an opioid-specific education series on rates of medication-assisted treatment for opioid use disorder in veterans

PURPOSE

The impact of a focused inpatient educational intervention on rates of medication-assisted therapy (MAT) for veterans with opioid use disorder (OUD) was evaluated.

METHODS

A retrospective cohort analysis compared rates of MAT, along with rates of OUD-related emergency department (ED) visits and/or hospital admission within 1 year, between veterans with a diagnosis of OUD who completed inpatient rehabilitation prior to implementation of a series of group sessions designed to engage intrinsic motivation to change behavior surrounding opioid abuse and provide education about MAT (the control group) and those who completed rehabilitation after implementation of the education program (the intervention group). A post hoc, multivariate analysis was performed to evaluate possible predictors of MAT use and ED and/or hospital readmission, including completion of the opioid series, gender, age (>45 years), race, and specific prior substance(s) of abuse.

RESULTS

One hundred fifty-eight patients were included: 95 in the control group and 63 in the intervention group. Rates of MAT were 25% (24 of 95 veterans) and 75% (47 of 63 veterans) in control and intervention groups, respectively (P < 0.01). Gender, completion of the opioid series, prior heroin use, and marijuana use met prespecified significance criteria for inclusion in multivariate regression modeling of association with MAT utilization, with participation in the opioid series (odds ratio [OR], 9.56; 95% confidence interval [CI], 4.36-20.96) and prior heroin use (OR, 3.26; 95% CI, 1.18-9.01) found to be significant predictors of MAT utilization on multivariate analysis. Opioid series participation and MAT use were independently associated with decreased rates of OUD-related ED visits and/or hospital admission (hazard ratios of 0.16 [95% CI, 0.06-0.44] and 0.32 [95% CI, 0.14-0.77], respectively) within 1 year after rehabilitation completion.

CONCLUSION

Focused OUD-related education in a substance abuse program for veterans with OUD increased rates of MAT and was associated with a decrease in OUD-related ED visits and/or hospital admission within 1 year.

Disparities in Access to Opioid Treatment Programs and Office-Based Buprenorphine Treatment Across the Rural-Urban and Area Deprivation Continua: A US Nationwide Small Area Analysis

OBJECTIVES

To measure access to opioid treatment programs (OTPs) and office-based buprenorphine treatment (OBBTs) at the smallest geographic unit for which the Census Bureau publishes demographic and socioeconomic data (ie, block group) and to explore disparities in access to treatment across the rural-urban and area deprivation continua across the United States.

METHODS

Access to OTPs and OBBTs at the block group in 2019 was quantified using an innovative 2-step floating catchment area technique that accounts for the supply of treatment facilities relative to the population size, proximity of facilities relative to the location of population in block groups, and time as a barrier within catchments. Block groups were stratified into tertiles based on the rural-urban continuum codes (metropolitan, micropolitan, small town, or rural) and area deprivation index (least-deprived, middle-deprived, most-deprived). The Integrated Nested Laplace Approximation approach was used for statistical analysis.

RESULTS

Across the United States, 3329 block groups corresponding to 2 915 949 adults lacked access to OTPs within a 2-hour drive of their community and 130 block groups corresponding to 86 605 adults did not have access to OBBTs. Disparities in access to treatment were observed across the urban-rural and area deprivation continua including (1) lowest mean access score to OBBTs were found among most-deprived small towns, and (2) lower mean access score to OTPs were found among micropolitan and small towns.

CONCLUSIONS

The results of this study revealed disparities in access to medication-assisted treatment. The findings call for creative initiatives and local and regional policies to develop to mitigate access problems.

Does a Rural Community-Based Intervention Improve Knowledge and Attitudes of Opioid Use Disorder and Medication-Assisted Treatment? A Report From the IT MATTTRs Study

Purpose

Understanding knowledge of and attitudes toward medication‐assisted treatment (MAT) for opioid use disorder (OUD) is important to changing the conversation about this devastating public health problem. While several studies report clinician knowledge and attitudes and training, less is known about community member perspectives. As part of the Implementing Technology and Medication Assisted Treatment Team Training in Rural Colorado study (IT MATTTRs), this study describes the implementation of community‐based interventions developed by rural community members and researchers to increase awareness and promote positive attitudes toward MAT for OUD and explores changes in community members’ OUD and MAT knowledge and beliefs.

Methods

Using the Boot Camp Translation process, the High Plains Research Network and Colorado Research Network MAT Advisory Councils developed multicomponent interventions on MAT for OUD. Baseline and postintervention surveys were administered using venue‐based sampling of community members in rural communities.

Findings

Surveys were completed by 789 community members at baseline and 798 at postintervention. Nearly half (49%) reported exposure to at least 1 intervention product. Greater exposure to intervention materials was associated with beliefs that using opioids to get high in rural communities is a problem (P < .0001), that opioid addiction is a chronic disease (P = .0032), and that OUD can be treated locally (P = .0003).

Conclusions

Partnering with local community members resulted in the successful development and implementation of community‐based interventions, exposure to which was associated with OUD knowledge and beliefs. Locally created interventions should be included in comprehensive approaches to stem the OUD epidemic.

Ketamine-facilitated behavioral treatment for cannabis use disorder: A proof of concept study

BACKGROUND

Sub-anesthetic ketamine infusions may benefit a range of psychiatric conditions, including alcohol and cocaine use disorders. Currently, there are no effective pharmacological treatments for cannabis use disorder.

OBJECTIVES

The objective of this uncontrolled proof of concept trial was to test the feasibility, tolerability, and potential therapeutic effects of integrating ketamine infusions with a behavioral platform of motivational enhancement therapy and mindfulness-based relapse prevention in treating cannabis use disorder (CUD).

METHODS

Eight cannabis-dependent individuals (four female, four male) receiving motivational enhancement therapy and mindfulness-based relapse prevention behavioral treatments completed this single-blind outpatient 6-week study. Participants received either one or two infusions of ketamine (0.71 mg/kg [infusion 1]; 1.41 mg/kg [infusion 2] for non-responders) during the study. Participants self-reported cannabis use (Timeline Follow-Back) and underwent an assessment of confidence in abstaining from using cannabis (Drug-Taking Confidence Questionnaire) at predetermined time points throughout the study.

RESULTS

Ketamine infusions were well-tolerated and there were no adverse events. Frequency of cannabis use decreased significantly from baseline (B = 5.1, s.e = 0.7) to the week following the first infusion (B = 0.8, s.e = 0.412), and remained reduced at the end of the study (B = 0.5, s.e = 0.3). Participants' confidence in their ability to abstain from cannabis in potentially triggering situations increased significantly from baseline to the end of study.

CONCLUSIONS

These findings suggest that combining ketamine with behavioral therapy is feasible,tolerable, and potentially helpful, in treating cannabis-dependent individuals.

Overcoming Barriers: Individual Experiences Obtaining Medication-Assisted Treatment for Opioid Use Disorder

Medication-assisted treatment (MAT) for opioid use disorder (OUD) is accessed half as often in rural versus urban areas in the United States. To better understand this disparity, we used a qualitative descriptive approach to explore the experiences of individuals with OUD seeking MAT in rural New Mexico. Guided interviews were conducted with 20 participants. The frameworks of critical social theory, intersectionality theory, and the brain opioid theory of social attachment were used to guide data analysis and interpretation. Thematic content analysis derived five major themes which identified novel barriers and facilitators to MAT success, including a perceived gender disparity in obtaining MAT, challenges in building a recovery-oriented support system, and the importance of navigating a new normal social identity. This deeper knowledge of the experiences and perspectives of rural individuals with OUD could serve to address the rural-urban MAT disparity, leading to enhanced recovery capacity and transformative policies.

The interaction of neonatal abstinence syndrome and opioid use disorder treatment availability for women insured by medicaid

OBJECTIVE

This paper will discuss the process of mapping opioid use disorder (OUD) treatment resources for pregnant women and discuss the intersection between treatment resources and rates of neonatal abstinence syndrome (NAS).

DESIGN

A resource manual was developed through a systematic process with stakeholders across Illinois. Resources were mapped by county and overlaid with county rates of NAS, using hospital discharge data.

RESULTS

Across Illinois, 89 treatment resources were identified for pregnant women insured by Medicaid. Resources were concentrated in 36% of Illinois' counties. Counties with limited treatment resources generally had high rates of NAS. Sixty-six percent of NAS cases among rural Illinois residents had no OUD treatment resources in their county. Rural counties had less access to medication-assisted treatment (MAT), the standard of care for treatment of OUD, compared with other counties across the state.

CONCLUSIONS

Efforts to increase OUD treatment options for pregnant women insured by Medicaid should concentrate on geographic areas with limited access and high need.

Organizational Facilitators and Barriers to Medication for Opioid Use Disorder Capacity Expansion and Use

Medication for opioid use disorder (MOUD) is a key strategy for addressing the opioid use disorder crisis, yet gaps in MOUD provision impede this strategy's benefits. The research reported here sought to understand what distinguishes low- and high-performing organizations in building and using capacity to provide MOUD. As part of a mixed methods MOUD implementation trial, semi-structured telephone interviews were conducted with personnel from low- and high-performing MOUD-providing organizations. Seventeen individuals from 17 organizations were interviewed. Findings demonstrate the importance of individual, organization, and community-level factors in supporting the building and use of MOUD capacity. Low- and high-performing organizations showed different patterns of facilitators and barriers during the implementation process. The key difference between low- and high-performing organizations was the level of organizational functioning. A better understanding of an organization's assets and deficits at the individual, organizational, and community levels would allow decision-makers to tailor their approaches to MOUD implementation.

Rates of prescription orders for United States active duty service members diagnosed with alcohol use disorder

BACKGROUND

Alcohol-use disorders (AUD) pose a significant challenge for the United States (US) military. The US Department of Defense has strongly recommended several medications for use in the treatment of patients with diagnosed AUD. This study assessed the prescription of medications for active duty service members (ADSMs) diagnosed with AUD in the US Military Health System (MHS). Methods: Rates of prescription orders were retrospectively examined from 2010 to 2017 among ADSMs with an incident diagnosis of moderate-to-severe AUD. The rate of prescription orders was defined as the proportion of ADSMs with an ICD-9 or ICD-10 diagnosis code of alcohol dependence who received an order for acamprosate, disulfiram, naltrexone, and/or topiramate at a military treatment facility in the year following their incident diagnosis. Results: ADSMs receiving an order for at least one medication in the year following their incident AUD diagnosis increased from 8.8% in 2010 to 16.2% in 2017 (RR = 1.84, 95% CI, 1.76, 1.93). Oral naltrexone was ordered most frequently among this patient population, while injectable naltrexone, a medication option meant to ease and improve adherence, was ordered for a smaller proportion of patients. Conclusions: Most ADSMs who might benefit from prescriptions for AUD are not receiving them as part of their treatment despite strong clinical evidence and Department of Defense policy support for their use among this cohort.

Psychosis and Comorbid Opioid Use Disorder: Characteristics and Outcomes in Opioid Substitution Therapy

Background and Objectives

Substance use disorders are highly prevalent among individuals with psychotic disorders and are associated with negative outcomes. This study aims to explore differences in characteristics and treatment outcomes for individuals with psychotic disorders when compared with individuals with other nonpsychotic psychiatric disorders enrolled in treatment for opioid use disorder (OUD).

Methods

Data were collected from a prospective cohort study of 415 individuals enrolled in outpatient methadone maintenance treatment (MMT). Psychiatric comorbidity was assessed using the Mini-International Neuropsychiatric Interview. Participants were followed for 12 months. Participant characteristics associated with having a psychotic disorder versus another nonpsychotic psychiatric disorder were explored by logistic regression analysis.

Results

Altogether, 37 individuals (9%) with a psychotic disorder were identified. Having a psychotic disorder was associated with less opioid-positive urine drug screens (odds ratio [OR] = 0.97, 95% confidence interval [CI] = 0.95, 0.99, P = .046). Twelve-month retention in treatment was not associated with psychotic disorder group status (OR = 0.73, 95% CI = 0.3, 1.77, P = .485). Participants with psychotic disorders were more likely to be prescribed antidepressants (OR = 2.12, 95% CI = 1.06, 4.22, P = .033), antipsychotics (OR = 3.57, 95% CI = 1.74, 7.32, P = .001), mood stabilizers (OR = 6.61, 95% CI = 1.51, 28.97, P = .012), and benzodiazepines (OR = 2.22, 95% CI = 1.11, 4.43, P = .024).

Discussion and Conclusions

This study contributes to the sparse literature on outcomes of individuals with psychotic disorders and OUD-receiving MMT. Rates of retention in treatment and opioid use are encouraging and contrast to the widely held belief that these individuals do more poorly in treatment. Higher rates of coprescription of sedating and QTc-prolonging medications in this group may pose unique safety concerns.

San Bernardino County Youth Opioid Response: Improving Access to Evidence-Based Medical Treatment for Opioid Use Disorder

Opioid use disorder (OUD) and related overdose deaths have become a crisis of epidemic proportions in the United States. In 2018, over 10 million people age 12 years or older misused opioids.Substance use is also correlated with increased physical and mental health disorders, and developmental challenges among youths. Medication-assisted treatment (MAT) has been reported to reduce mortality, opioid use, and human immunodeficiency virus and hepatitis C virus transmission while increasing treatment retention in adults. The San Bernardino County Youth Opioid Response (SBCYOR) program was formed to explore best practices for youths at risk of opioid use disorders and/or overdose. SBCYOR is a coalition of professionals in healthcare, behavioral health, public education, law enforcement, emergency medical services (EMS) agencies, and juvenile detention centers throughout San Bernardino County, California. SBCYOR focuses on high-risk and addicted individuals between the ages of 12 to 24 years in San Bernardino County’s correctional system. It utilizes a strategy of collaboration, prevention, risk mitigation, medication, psychological treatment, and community outreach. This study aimed to evaluate the implementation and progress of SBCYOR.

A review of the pharmacogenomics of buprenorphine for the treatment of opioid use disorder

As the opioid epidemic continues to grow across the United States, the number of patients requiring treatment for opioid use disorder continues to climb. Although medication-assisted treatment presents a highly effective tool that can help address this epidemic, its use has been limited. Nonetheless, with easier dosing protocols (compared to the more complex dosing required of methadone due to its long and variable half-life) and fewer prescribing limitations (may be prescribed outside the setting of federally approved clinics), the increase in buprenorphine use in the United States has been dramatic in recent years. Despite buprenorphine's demonstrated efficacy, patient-specific factors can alter the response to the medications, which may lead to treatment failure in some patients. Clinical characteristics (sex, concurrent medications, and mental health comorbidities) as well as social determinants of health (housing status, involvement with the criminal justice system, and socioeconomic status) may impact treatment outcomes. Furthermore, a growing body of data suggests that genetic variations can alter pharmacological effects and influence therapeutic response. This review will cover the available pharmacogenomic data for the use of buprenorphine in the management of opioid use disorders. Pharmacogenomic determinants that affect opioid receptors, the dopaminergic system, metabolism of buprenorphine, and adverse events are discussed. Although much of the existing data comes from observational studies, clinical research is ongoing. Nevertheless, the development of pharmacogenomic-guided strategies has the potential to reduce opioid misuse, improve clinical outcomes, and save healthcare resources.

Buprenorphine-naloxone use in pregnancy: a systematic review and metaanalysis

OBJECTIVE

The goal of this systematic review and metaanalysis is to compare pregnancy outcomes between pregnant women undergoing treatment for opioid use disorder with buprenorphine-naloxone and those undergoing treatment for opioid use disorder with other forms of medication-assisted treatment.

STUDY DESIGN

PubMed, Embase, PsycINFO, Cochrane Clinical Trials, and Web of Science were searched to identify studies assessing the relationship between maternal buprenorphine-naloxone use and pregnancy outcomes. Outcomes assessed included neonatal abstinence syndrome diagnosis and treatment, neonatal intensive care unit admission, length of neonatal hospital stay, delivery complications, mode of delivery, labor analgesia, illicit drug use, medication-assisted treatment dosage, gestational age at delivery, breastfeeding status, miscarriage, congenital anomalies, intrauterine fetal demise, birthweight, head circumference, length, and Apgar scores.

RESULTS

Overall, 5 studies comprising 6 study groups met the inclusion criteria. Of the 1875 mother-baby dyads available for analysis, medications prescribed as part of the medication-assisted treatment included buprenorphine-naloxone, buprenorphine alone, methadone, or long-acting opioids. There were no serious adverse maternal or neonatal outcomes associated with maternal buprenorphine-naloxone use reported among any of the studies. Women prescribed with buprenorphine-naloxone for delivered neonates who were less likely to require treatment for neonatal abstinence syndrome were compared with pregnant women prescribed with other opioid agonist medications. Of the remaining outcomes assessed, metaanalysis did not detect any statistically significant differences when comparing the groups of women using buprenorphine-naloxone with the groups of women prescribed with other medications as part of the medication-assisted treatment.

CONCLUSION

Pregnant women undergoing treatment for opioid use disorder with buprenorphine-naloxone do not experience significantly different pregnancy outcomes than women undergoing treatment with other forms of opioid agonist medication-assisted therapy.

Perceptions of extended-release buprenorphine injections for opioid use disorder among people who regularly use opioids in Australia

AIMS

To examine perceptions of extended-release (XR) buprenorphine injections among people who regularly use opioids in Australia.

DESIGN

Cross-sectional survey prior to implementation. XR-buprenorphine was registered in Australia in November 2018.

SETTING

Sydney, Melbourne and Hobart. Participants A total of 402 people who regularly use opioids interviewed December 2017 to March 2018.

MEASUREMENTS

Primary outcome concerned the proportion of participants who believed XR-buprenorphine would be a good treatment option for them, preferred weekly versus monthly injections and perceived advantages/disadvantages of XR-buprenorphine. Independent variables concerned the demographic characteristics and features of current opioid agonist treatment (OAT; medication-type, dose, prescriber/dosing setting, unsupervised doses, out-of-pocket expenses and travel distance).

FINDINGS

Sixty-eight per cent [95% confidence interval (CI) = 63-73%] believed XR-buprenorphine was a good treatment option for them. They were more likely to report being younger [26-35 versus > 55 years; odds ratio (OR) = 3.16, 95% CI = 1.12-8.89; P = 0.029], being female (OR = 1.67, 95% CI = 1.04-2.69; P = 0.034), < 10 years school education (OR = 1.87, 95% CI = 1.12-3.12; P = 0.016) and past-month heroin (OR = 1.81, 95% CI = 1.15-2.85; P = 0.006) and methamphetamine use (OR = 1.90, 95% CI = 1.20-3.01; P = 0.006). Fifty-four per cent reported no preference for weekly versus monthly injections, 7% preferred weekly and 39% preferred monthly. Among OAT recipients (n = 255), believing XR-buprenorphine was a good treatment option was associated with shorter treatment episodes (1-2 versus ≥ 2 years; OR = 3.93, 95% CI = 1.26-12.22; P = 0.018), fewer unsupervised doses (≤ 8 doses past-month versus no take-aways; OR = 0.50; 95% CI = 0.27-0.93; P = 0.028) and longer travel distance (≥ 5 versus < 5 km; OR = 2.10, 95% CI = 1.20-3.65; P = 0.009). Sixty-nine per cent reported 'no problems or concerns' with potential differences in availability, flexibility and location of XR-buprenorphine.

CONCLUSIONS

Among regular opioid users in Australia, perceptions of extended-release buprenorphine as a good treatment option are associated with being female, recent illicit drug use and factors relating to the (in)convenience of current opioid agonist treatment.

Continuous Epidural Hydromorphone Infusion for Post-Cesarean Delivery Analgesia in a Patient on Methadone Maintenance Therapy: A Case Report

The prevalence of opioid use disorder (OUD) in the United States has more than quadrupled over the past two decades. This patient population presents a number of challenges to clinicians, including difficult pain management after surgical procedures due to the development of opioid tolerance. Significantly greater opioid consumption and pain scores after cesarean delivery have been reported in patients with OUD compared to other obstetric patients. A multi-modal analgesic regimen is generally recommended, but there are few well-established pain management strategies after cesarean delivery specific to patients with OUD. We present the case of a patient with OUD maintained on daily methadone that received a continuous epidural hydromorphone infusion for post-cesarean analgesia, a technique not previously reported in obstetric patients and only rarely described for patients undergoing other surgical procedures. The patient received epidural anesthesia for cesarean delivery, and after surgery, the epidural catheter was left in place for the epidural hydromorphone infusion, initiated at 140 mcg/hr and continued for approximately 40 hrs. This strategy reduced her average daily oral opioid consumption by 97%, reduced self-reported pain scores, shortened the length of hospitalization and improved ability to ambulate compared to her previous cesarean delivery. The use of continuous epidural hydromorphone infusion was effective in this case, and this analgesic technique may also be applicable to other types of surgical procedures with the potential for significant post-operative pain, particularly in patients with OUD.
