A population-based examination of trends and disparities in medication treatment for opioid use disorders among Medicaid enrollees

Diversity inclusion in United States opioid pharmacological treatment trials: A systematic review

Pharmacological treatments for opioid use disorders (OUDs) may have mixed efficacy across diverse groups, i.e., sex/gender, race/ethnicity, and socioeconomic status (SES). The present systematic review aims to examine how diverse groups have been included in U.S. randomized clinical trials examining pharmacological treatments (i.e., methadone, buprenorphine, or naltrexone) for OUDs. PubMed was systematically searched according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The initial search yielded 567 articles. After exclusion of ineligible articles, 50 remained for the present review. Of the included articles, 14.0% (n = 7) reported both full (i.e., accounting for all participants) sex/gender and race/ethnicity information; only two of those articles also included information about any SES indicators. Moreover, only 22.0% (n = 11) reported full sex/gender information, and 42.0% (n = 21) reported full racial/ethnic information. Furthermore, only 10.0% (n = 5) reported that their lack of subgroup analyses or diverse samples was a limitation to their studies. Particularly underrepresented were American Indian/Alaska Native (AI/AN), Asian, Native Hawaiian/Other Pacific Islander (NH/OPI), and multiracial individuals. These results also varied by medication type; Black individuals were underrepresented in buprenorphine randomized controlled trials (RCTs) but were well represented in RCTs for methadone and/or naltrexone. In conclusion, it is critical that all people receive efficacious pharmacological care for OUDs given the ongoing opioid epidemic. Findings from the present review, however, support that participants from diverse or marginalized backgrounds are underrepresented in treatment trials, despite being at increased risk for disparities related to OUDs. Suggestions for future research are advanced. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Trends in visits to substance use disorder treatment facilities in 2020

OBJECTIVE

To describe weekly changes in the number of substance use disorder treatment (SUDT) facility visits in 2020 compared to 2019 using cell phone location data.

METHODS

We calculated the percentage weekly change in visits to SUDT facilities from the week of January 5 through the week of October 11, 2020, relative to the week of January 6 through the week of October 13, 2019. We stratified facilities by county COVID-19 incidence per 10,000 residents in each week and by 2018 fatal drug overdose rate. Finally, we conducted a multivariable linear regression analysis examining percent change in visits per week as a function of county-level COVID-19 tercile, a series of calendar month indicators, and the interaction of county-level COVID-19 tercile and month. We repeated the regression analysis replacing COVID-19 tercile with overdose tercile.

RESULTS

Beginning the eleventh week of 2020, the number of visits to SUDT facilities declined substantially, reaching a nadir of 48% of 2019 visits in early July. In contrast to January, there were significantly fewer visits in 2020 compared to 2019 in all subsequent months (p < 0.01 in all months). Multivariable regression results found that facilities in the tercile of counties experiencing the most COVID-19 cases had a significantly greater reduction in the number of SUDT visits in 2020 for the months of June through August than facilities in counties with the fewest COVID-19 rates (p < 0.05). The study found no statistically significant difference in the change in the number of visits by facilities in counties with historically different overdose rates.

DISCUSSION

Our findings support the hypothesis that a reduction has occurred in the average weekly number of visits to SUDT facilities. The size of the effect differs based on the number of COVID-19 cases but not on historical overdose rate.

Addressing Racial And Ethnic Disparities In The Use Of Medications For Opioid Use Disorder

Social discourse about the opioid crisis in the US has focused on White populations, even though opioid-related deaths have grown at a higher rate among people of color than among non-Hispanic White people in recent years. Medications for opioid use disorder (OUD) are the gold standard for treating OUD and preventing overdose but are underused among people with OUD, with disproportionately low treatment initiation and retention among people of color. Methadone, which is highly stigmatized and has a more burdensome treatment regimen, is the predominant medication for OUD available to people of color. To address disparities in the initiation and retention of treatment using medication for OUD, policy makers should consider strategies such as Medicaid expansion, increased grant funding for federally qualified health centers to provide buprenorphine treatment, retention of temporary telehealth policies that allow remote buprenorphine induction, and regulatory changes to allow methadone treatment in office-based practices.

Financial sustainability of payment models for office-based opioid treatment in outpatient clinics

BACKGROUND

Office-Based Opioid Treatment (OBOT) is a delivery model which seeks to make medications for opioid use disorder (MOUD), particularly buprenorphine, widely available in general medical clinics and offices. Despite evidence supporting its effectiveness and cost-effectiveness, uptake of the OBOT model has been relatively slow. One important barrier to faster diffusion of OBOT may be the financial challenges facing clinics that could adopt it.

METHODS

We review key features and variants of the OBOT model, then discuss different approaches that have been used to fund it, and the findings from previous economic analyses of OBOT's impact on organizational finances. We conclude by discussing the implications of these analyses for the financial sustainability of the OBOT delivery model.

RESULTS

Like other novel services, OBOT poses challenges for providers due to its reliance on services which are 'non-billable' in a fee-for-service environment. A variety of approaches exist for covering the non-billable costs, but which approaches are feasible depends on local payer policies. The scale of the challenges varies with clinic size, organizational affiliations and the policies of the state where the clinic operates. Small clinics in a purely fee-for-service environment may be particularly challenged in pursuing OBOT, given the need to fund a dedicated staff and extra administrative work. The current pandemic may pose both opportunities and challenges for the sustainability of OBOT, with expanded access to telemedicine, but also uncertainty about the durability of the expansion.

CONCLUSION

The reimbursement environment for OBOT delivery varies widely around the US, and is evolving as Medicare (and possibly other payers) introduce alternative payment approaches. Clinics considering adoption of OBOT are well advised to thoroughly investigate these issues as they make their decision. In addition, payers will need to rethink how they pay for OBOT to make it sustainable.

Who stays in medication treatment for opioid use disorder? A national study of outpatient specialty treatment settings

BACKGROUND

Maintenance treatments with medications for opioid use disorder (MOUD) are highly effective at reducing overdose risk while patients remain in care. However, few patients initiate medication and retention remains a critical challenge across settings. Much remains to be learned about individual and structural factors that influence successful retention, especially among populations dispensed MOUD in outpatient settings.

METHODS

We examined individual and structural characteristics associated with MOUD treatment retention among a national sample of adults seeking MOUD treatment in outpatient substance use treatment settings using the 2017 Treatment Episode Dataset-Discharges (TEDS-D). The study assessed predictors of retention in MOUD using multivariate logistic regression and accelerated time failure models.

RESULTS

Of 130,300 episodes of MOUD treatment in outpatient settings, 36% involved a duration of care greater than six months. The strongest risk factors for treatment discontinuation by six months included being of younger age, ages 18-29 ((OR):0.52 [95%CI:0.50-0.54]) or 30-39 (OR:0.57 [95%CI:0.55-0.59); experiencing homelessness (OR: 0.70 [95%CI:0.66-0.73]); co-using methamphetamine (OR:0.48 [95%CI:0.45-0.51]); and being referred to treatment by a criminal justice source (OR:0.55 [95%CI:0.52-0.59) or by a school, employer, or community source (OR:0.71 [95%CI:0.66-0.76).

CONCLUSIONS

Improving retention in treatment is a pivotal stage in the OUD cascade of care and is critical to reducing overdose deaths. Efforts should prioritize interventions to improve retention among patients who are both prescribed and dispended MOUD, especially youth, people experiencing homelessness, polysubstance users, and people referred to care by the justice system who have especially short stays in care.

Growing racial/ethnic disparities in buprenorphine distribution in the United States, 2007-2017

OBJECTIVE

To assess whether per capita buprenorphine distribution varies by regional racial/ethnic composition, Medicaid expansion status, and time period.

METHODS

Our unit of analysis -- three-digit ZIP codes ("ZIP3s") -- was classified into quintiles based on percentage of White residents. A weighted linear regression model of buprenorphine distribution -- including White resident quintile, waivered prescriber rate, overdose rate, sociodemographic factors, and year fixed effects -- was estimated using national buprenorphine distribution data from 2007 to 2017. We report predictive margins of the buprenorphine distribution rate by quintile, as well as average marginal effects of waivered prescriber rate on buprenorphine distribution rate for each quintile. Analyses were stratified by Medicaid expansion status and time period (2007-2010, 2011-2014, 2015-2017).

RESULTS

Buprenorphine distribution increased nationally during 2007-2017, yet growth was disproportionately greater for ZIP3s with higher percentages of White residents. Medicaid expansion states exhibited significant differences in buprenorphine distribution across ZIP3 quintiles during 2007-2010, the magnitude of which increased across time periods. Non-expansion states exhibited significant quintile differences during 2011-2014 and 2015-2017. The average marginal effect of increasing the waivered prescriber rate on the distribution rate was consistently smaller in ZIP3s with lower percentages of White residents, particularly in expansion states.

CONCLUSIONS

We find ecological evidence consistent with racial/ethnic disparities in buprenorphine distribution. Our finding that increasing the waivered prescriber rate had differential effects by ZIP3 racial/ethnic composition suggest that broad initiatives to increase the number of waivered prescribers are likely insufficient to achieve equitable buprenorphine access. Rather, targeted and tailored policy efforts are warranted.

Opioid use disorder and COVID-19: Implications for policy and practice

ABSTRACT

Preliminary data suggest that opioid-related overdose deaths have increased subsequent to COVID-19. Despite national support for expanding the role of physician assistants (PAs) and NPs in serving patients with opioid use disorder, these clinicians are held to complex and stringent regulatory barriers. COVID-19 triggered significant changes from regulatory and federal agencies, yet disparate policies and regulations persist between physicians and PAs and NPs. The dual epidemics of COVID-19 and opioid use disorder highlight the inadequate infrastructure required to support patients, communities, and clinicians, and may serve as the catalyst for eliminating barriers to care.

Postpartum Treatment for Substance Use Disorder Among Mothers of Infants with Neonatal Abstinence Syndrome and Prenatal Substance Exposure

Background: Little is known about rates of substance use disorder (SUD) treatment for women in dyads affected by substance use in the immediate postpartum period. This study's objectives were to (1) identify characteristics of mothers of infants with neonatal abstinence syndrome (NAS) and/or prenatal substance exposure (PSE) who did or did not receive SUD treatment in the first 60 days postpartum and (2) describe timing of treatment receipt. Methods: This descriptive study examined linked mother-infant dyads using Medicaid data from Louisiana, Massachusetts, and Wisconsin for 2006-2009. Dyads were included if the infant had NAS and/or PSE. Descriptive statistics on sociodemographic characteristics, prenatal SUD, mental health conditions, Medicaid enrollment, and health care utilization were reported for women who did and did not receive SUD treatment in the first 60 days postpartum. The distribution of each variable was compared using chi-square tests. The timing of first postpartum treatment in weeks since delivery was examined. Results: Among Medicaid-insured women whose infants had in utero substance exposure, 15% received any postpartum SUD treatment. Fewer than half were diagnosed with SUD prenatally. Of those who received postpartum SUD treatment, 68% had received prenatal treatment. No association was observed between postpartum SUD treatment receipt and months of Medicaid enrollment in the year before delivery, prenatal visits, or postpartum visit attendance. Conclusions: Most women who likely need postpartum SUD treatment did not receive it and multipronged solutions are needed. These findings provide a useful baseline for evaluations of policies aimed at improving maternal health.

Self-reported Health Diagnoses and Demographic Correlates With Kratom Use: Results From an Online Survey

OBJECTIVES

To determine whether diagnosed pre-existing health conditions correlate with Kratom demographics and use patterns.

METHODS

A cross-sectional, anonymous US national online survey was conducted among 8049 Kratom users in October, 2016 to obtain demographic, health, and Kratom use pattern information.

RESULTS

People who use Kratom to mitigate illicit drug dependence self-reported less pain and better overall health than individuals who used Kratom for acute/chronic pain. Self-reported improvements in pre-existing mental health symptoms (attention deficit and hyperactivity disorder/attention deficit disorder, anxiety, bipolar disorder, post-traumatic stress disorder, and depression) attributed to Kratom use were greater than those related to somatic symptoms (back pain, rheumatoid arthritis, acute pain, chronic pain, fibromyalgia). Demographic variables, including female sex, older age, employment status, and insurance coverage correlated with increased likelihood of Kratom use.

CONCLUSIONS

Kratom use may serve as a self-treatment strategy for a diverse population of patients with pre-existing health diagnoses. Healthcare providers need to be engaging with patients to address safety concerns and potential limitations of its use in clinical practice for specific health conditions.

Quality of Buprenorphine Care for Insured Adults With Opioid Use Disorder

AIM

The aim of this study was to characterize quality of buprenorphine care for opioid use disorder (OUD) by quantifying buprenorphine initiation, engagement, and maintenance for individuals in a large, diverse, real-world cohort in the United States.

DESIGN

This was a retrospective cohort analysis.

SETTING

OUD treatment in the outpatient setting.

PARTICIPANTS

A total of 45,210 commercially insured and Medicare Advantage (MA) enrollees 18 years or older in the OptumLabs Data Warehouse with an index diagnosis of OUD between January 1, 2018 and December 31, 2018.

INTERVENTIONS

Treatment with buprenorphine.

MEASUREMENTS

We calculated 6 measures of buprenorphine treatment quality. We conducted survival analyses to characterize treatment duration and logistic regressions to evaluate the association between clinical and sociodemographic characteristics and quality.

FINDINGS

Of 45,210 eligible individuals with OUD, ∼1 in 10 (n=4600, 10.2%) initiated buprenorphine within 365 days following diagnosis (Measure #1) and 2850 individuals (6.3%) initiated buprenorphine within 14 days of diagnosis (Measure #2). Of individuals initiating treatment within 14 days of diagnosis, 1769 (62.1%) had 2 or more buprenorphine claims within 34 days of initiation (Measure #3). Of the 4600 individuals who received buprenorphine, 2300 (50.0%) were maintained in care with 180 days or more of covered buprenorphine treatment during 365 days after diagnosis (Measure #4). Finally, of the 4600 individuals who received buprenorphine, 2543 (55.3%) did not fill any other concurrent opioid analgesic (Measure #5) and 2951 (64.2%) did not fill any concurrent benzodiazepine (Measure #6). Quality was generally lower for individuals with MA compared with commercial coverage and among Hispanic and Black adults compared with White adults.

CONCLUSION

Widespread gaps exist in quality of buprenorphine treatment initiation, engagement, and maintenance among commercially insured and MA enrollees with OUD.

Buprenorphine use and disparities in access among emergency department patients with opioid use disorder: A cross-sectional study

BACKGROUND

Buprenorphine, a partial mu-opioid agonist and kappa-opioid antagonist, is an approved treatment for opioid use disorder (OUD). Studies demonstrate that buprenorphine decreases cravings for other opioids, effectively ameliorates withdrawal symptoms, and decreases opioid overdose and mortality. However, buprenorphine remains under-utilized. Despite its low potential for misuse, research has reported wide use of non-prescribed buprenorphine, seemingly for its effectiveness in treating withdrawal and helping to maintain sobriety. We designed our study to describe patient experiences with both prescribed and non-prescribed buprenorphine usage and to identify potential disparities in buprenorphine access within a high-risk population of patients with OUD.

METHODS

This was a cross-sectional study conducted in the emergency department (ED) of a large inner-city university hospital from January 15, 2015, through April 30, 2018. Patients were eligible to participate in the study if they presented with opioid intoxication or after an opioid overdose and were 18 years of age or older. Research assistants administered surveys after the ED team deemed an eligible patient to be clinically sober.

RESULTS

The study enrolled 423 patients. Most patients in this study were white (59.8%) and male (77.5%), with a mean age of 37.5 years. A majority of patients (58.4%) had Medicaid insurance. Of those, 15.8% had previously been on medication for opioid use disorder (MOUD) with methadone, and 16.3% received outpatient buprenorphine. Most (72.8%, 95% CI 68.6-77.0%) respondents reported having used buprenorphine at one point. Of the participants reporting prior buprenorphine use, 15.5% had either traded, shared, or sold their buprenorphine in the past. Patients who obtained non-prescribed buprenorphine generally purchased it from a dealer, took only 8 mg at a time, and paid $10 per dose. Of those patients with a history of using buprenorphine, only 3.2% reported taking buprenorphine for euphoric effects, though 45.5% of participants declined to provide a specific reason for using the drug. Patients younger than 40 were more likely than those older than 40 to have taken buprenorphine in the past (81% vs 60%, p < 0.001). Further, white patients were more likely than nonwhite patients to have both used (42% vs 31%) and been prescribed buprenorphine (46% vs 25%, p < 0.001).

DISCUSSION

Familiarity with buprenorphine is high among patients with OUD, and our data show that there is a strong demand among these patients for access to legal buprenorphine-based treatment programs. However, a variety of issues hamper access to this medication. Most patients in our study reported having been to an in-patient detox or rehabilitation program, yet only 16% of patients participated in a buprenorphine-based program. Furthermore, less than half of patients surveyed (37%) received a prescription for buprenorphine, and few participants reported taking buprenorphine for euphoric effects. Our findings suggest that a major barrier exists in legally obtaining buprenorphine for treatment of OUD, and that there appear to be racial and other disparities in buprenorphine prescribing, further limiting access to patients. Buprenorphine access needs to be expanded to satisfy the unmet need for appropriate treatment of those struggling with OUD, with particular attention to older and nonwhite patients.

Use of buprenorphine for those with employer-sponsored insurance during the initial phase of the COVID-19 pandemic

OBJECTIVE

To quantify weekly rates of use of buprenorphine for those with employer-based insurance and whether the rate differs based on county-level measures of race, historical fatal drug overdose rate, and COVID-19 case rate.

METHODS

We used 2020 pharmaceutical claims for 4.8 million adults from a privately insured population to examine changes in the use of buprenorphine to treat opioid use disorder in 2020 during the onset of the COVID-19 pandemic. We quantified variation by examining changes in use rates across counties based on their fatal drug overdose rate in 2018, number of COVID-19 cases per capita, and percent nonwhite.

RESULTS

Weekly use of buprenorphine was relatively stable between the first week of January (0.6 per 10,000 enrollees, 95%CI = 0.2 to 1.1) and the last week of August (0.8 per 10,000 enrollees, 95%CI = 0.4 to 1.3). We did not find evidence of any consistent change in use of buprenorphine by county-level terciles for COVID-19 rate as of August 31, 2020, age-adjusted fatal drug overdose rate, and percent nonwhite. Use was consistently higher for counties in the highest tercile of county age-adjusted fatal drug overdose rate when compared to counties in the lowest tercile of county age-adjusted fatal drug overdose rate.

DISCUSSION

Our results provide early evidence that new federal- and state-level policies may have steadied the rate of using buprenorphine for those with employer-based insurance during the pandemic.

Racial/ethnic differences in prescription opioid misuse and heroin use among a national sample, 1999-2018

OBJECTIVE

To characterize racial/ethnic differences in past-year prescription opioid misuse and heroin use.

METHODS

Data on 1,117,086 individuals age 12 and older were from the 1999-2018 National Survey on Drug Use and Health. We compared relative prevalences across 6 racial/ethnic groups for prescription opioid misuse analyses and 4 racial/ethnic groups for heroin analyses. Unadjusted and gender- and age-adjusted prevalences are reported for 5 time periods (1999-2002, 2003-2006, 2007-2010, 2011-2014, 2015-2018). Survey-weighted Poisson regression models with robust variance were used to estimate risk ratios by race/ethnicity and to test for time trends.

RESULTS

Prescription opioid misuse was significantly higher among non-Hispanic White individuals than among Black, Hispanic, and Asian individuals across all time periods, yet was highest among Native American individuals in every time period. The relative difference between White and both Hispanic and Asian individuals significantly widened over time, whereas the gap between Black and White individuals significantly decreased. Early in the study period, heroin use was highest among Black and Hispanic individuals. Heroin use among White individuals first surpassed all other groups in 2007-2010 and continued to steadily increase, more than doubling from 1999-2002 to 2015-2018.

CONCLUSIONS

While heroin use has risen among all racial/ethnic groups, the demographics of heroin use have changed significantly in the past two decades such that prevalence is now highest among White individuals. Opioid prevention and treatment initiatives should both be informed by the changing demographics of heroin use and seek to reduce opioid-related harms and expand treatment access equitably for all racial/ethnic groups.

Addressing racial & socioeconomic disparities in access to medications for opioid use disorder amid COVID-19

•

Pre-COVID-19, stark racial disparities characterized the landscape of access to medications for opioid use disorder, especially buprenorphine

•

Telemedicine uptake provides flexibility for patients on buprenorphine but considerable risks remain for those on methadone

•

Lifting the X-waiver requirement would increase buprenorphine access by increasing the pool of buprenorphine prescribers

•

Patients should be offered both buprenorphine and methadone as treatment options when clinically indicated

•

With COVID-19, methadone should be delivered to patients’ homes, and eventually accessible in community pharmacies

Barriers to accessing opioid agonist therapy in pregnancy

BACKGROUND

The incidence of opioid use disorder during pregnancy has risen dramatically in the last couple of decades. Despite the safety and efficacy of treatment for opioid use during pregnancy, pregnant women often cannot access treatment.

OBJECTIVE

This study aimed to determine the availability of opioid agonist therapy to pregnant women in Missouri and Illinois and to compare different markers of treatment accessibility between opioid treatment programs and buprenorphine providers and between rural and urban practices.

STUDY DESIGN

Buprenorphine providers and opioid treatment programs in Missouri and Illinois were identified using the Substance Abuse and Mental Health Services Administration website. A phone audit was conducted to evaluate barriers to care, including whether clinics accepted new patients, pregnant patients, and insurance, and the time to the first appointment and appointment cost. Rural-urban commuting area codes and practice ZIP codes were used to determine whether practice location was rural or urban. Provider specialty was determined from state licensing databases.

RESULTS

There were 1363 buprenorphine providers and 98 opioid treatment programs listed. Clinics were clustered around metropolitan areas, and only 13% of buprenorphine providers (183 of 1363) and 5% of opioid treatment programs (5 of 98) were in rural areas. Despite 3 contact attempts for each clinic, we were unable to reach 42% of buprenorphine providers (401 of 965) and 14% of opioid treatment programs (14 of 98). Of those reached, 40% of buprenorphine providers (223 of 564) and 80% of opioid treatment programs (67 of 84) were accepting new pregnant patients (P=.01). Buprenorphine providers required more contact attempts (>2 attempts in 34% vs 15%; P<.0001) and had longer wait times for the first appointment (>7 days in 27% vs 4%; P=.002) than opioid treatment programs. Buprenorphine providers in urban areas required more attempts to reach (>2 attempts in 36% vs 24%; P=.03) and were less likely to accept Medicaid than those in rural areas (52% vs 74%; P=.008). More than 23% of buprenorphine provider listings (238 of 1038) contained incorrect information, whereas no opioid treatment program listing had incorrect information. Most buprenorphine providers were in primary care or psychiatry, whereas <5% of buprenorphine providers (43 of 1363) were obstetrician-gynecologists.

CONCLUSION

This is the first phone audit to evaluate access to opioid agonist therapy for pregnant women. Only a minority of buprenorphine providers offered care for this patient population, and a large proportion required multiple contact attempts and wait times of >7 days. Opioid treatment programs were more responsive and accepting of new pregnant patients but comprised a minority of clinics and were predominately located in urban areas. There is an urgent need for improved reliability of contact information for opioid agonist providers, timely intake and acceptance for treatment of pregnant patients, and overall improved access to clinics that are challenged by geographic and insurance status barriers.

Improving Research Quality to Achieve Mental Health Equity

Inequities and the resulting disparities that exist in mental health for a variety of socially disadvantaged groups have roots in the history and ongoing processes of medical and mental health research, as well as in persisting implicit bias in our society and health care system. The inclusion of historically excluded communities in the research to practice pipeline is vital to ensuring that treatments and interventions are developed to increase equity in mental health. A research framework is proposed based on the integration of community-based participatory research and human-centered design as an avenue for removing inequities and barriers in mental health.

The opioid crisis: a contextual, social-ecological framework

The prevalence of opioid use and misuse has provoked a staggering number of deaths over the past two and a half decades. Much attention has focused on individual risks according to various characteristics and experiences. However, broader social and contextual domains are also essential contributors to the opioid crisis such as interpersonal relationships and the conditions of the community and society that people live in. Despite efforts to tackle the issue, the rates of opioid misuse and non-fatal and fatal overdose remain high. Many call for a broad public health approach, but articulation of what such a strategy could entail has not been fully realised. In order to improve the awareness surrounding opioid misuse, we developed a social-ecological framework that helps conceptualise the multivariable risk factors of opioid misuse and facilitates reviewing them in individual, interpersonal, communal and societal levels. Our framework illustrates the multi-layer complexity of the opioid crisis that more completely captures the crisis as a multidimensional issue requiring a broader and integrated approach to prevention and treatment.

Attitudes toward opioid use disorder medications: Results from a U.S. national study of individuals who resolved a substance use problem

The attitudes of individuals who receive, provide, or influence opioid use disorder (OUD) medication services, also called stakeholders, may enhance or hinder their dissemination and adoption. Individuals who have resolved a significant alcohol or other drug (AOD) problem are a group of key stakeholders whose OUD medication attitudes are not well understood empirically. This group subsumes, but is not limited to, individuals who identify as being "in recovery." Analyses leveraged the National Recovery Study, a geo-demographically representative survey of U.S. adults who resolved a significant AOD problem (N = 1,946). We examined the prevalence of positive, neutral, and negative attitudes toward agonists, such as buprenorphine/naloxone and methadone, and antagonists, such as oral and extended-release depot injection naltrexone. Single-predictor logistic regression models tested for demographic, clinical, and recovery-related correlates of these attitudes and, for those significant at the .1 level, multivariable-predictor logistic regression models tested unique associations between these correlates and attitudes. Results showed that participants were equally likely to hold positive (21.4 [18.9-24.0]%) and negative agonist (23.8 [21.2-26.7]%) attitudes but significantly more likely to hold negative (30.3 [27.4-33.3]%) than positive antagonist attitudes (18.0 [15.9-20.4]%). Neutral attitudes were most commonly endorsed for both agonists (54.8 [51.6-57.9]%) and antagonists (51.7 [48.5-54.8]%). For agonists, more recent AOD problem resolution was a unique predictor of positive attitude, whereas Black and Hispanic races/ethnicities, compared with White, were unique predictors of negative attitude. For antagonists, older age group (45-59 and 60 + vs. 18-29 years), lifetime opioid antagonist medication prescription, and past 90-day non-12-step mutual-help attendance were unique predictors of positive attitude, whereas greater spirituality was a unique predictor of negative attitude. This population-level study of U.S. adults who resolved an AOD problem showed that agonist attitudes may be more positive than anecdotal evidence suggests. Certain characteristics and experiences, however, highlight a greater likelihood of negative attitudes, suggesting these factors may be potential barriers to OUD medication adoption.

Place, poverty and prescriptions: a cross-sectional study using Area Deprivation Index to assess opioid use and drug-poisoning mortality in the USA from 2012 to 2017

OBJECTIVE

To identify the relationships between county-level area deprivation and patterns of both opioid prescriptions and drug-poisoning mortality.

DESIGN, SETTING AND PARTICIPANTS

For this retrospective cross-sectional study, we used the IQVIA Xponent data to capture opioid prescriptions and Centres for Disease Control and Prevention National Vital Statistics System to assess drug-poisoning mortality. The Area Deprivation Index (ADI) is a composite measure of social determinants of health comprised of 17 US census indicators, spanning four socioeconomic domains. For all US counties with available opioid prescription (2712 counties) and drug-poisoning mortality (3133 counties) data between 2012 and 2017, we used negative binomial regression to examine the association between quintiles of county-level ADI and the rates of opioid prescriptions and drug-poisoning mortality adjusted for year, age, race and sex.

PRIMARY OUTCOME MEASURES

County-level opioid prescription fills and drug-poisoning mortality.

RESULTS

Between 2012 and 2017, overall rates of opioid prescriptions decreased from 96.6 to 72.2 per 100 people, while the rates of drug-poisoning mortality increased from 14.3 to 22.8 per 100 000 people. Opioid prescription and drug-poisoning mortality rates were consistently higher with greater levels of deprivation. The risk of filling an opioid prescription was 72% higher, and the risk of drug-poisoning mortality was 36% higher, for most deprived compared with the least deprived counties (both p<0.001).

DISCUSSION

Counties with greater area-level deprivation have higher rates of filled opioid prescriptions and drug-poisoning mortality. Although opioid prescription rates declined across all ADI quintiles, the rates of drug-poisoning mortality continued to rise proportionately in each ADI quintile. This underscores the need for individualised and targeted interventions that consider the deprivation of communities where people live.

Medication for opioid use disorder treatment and specialty outpatient substance use treatment outcomes: Differences in retention and completion among opioid-related discharges in 2016

Opioid medication treatment access is a public health priority aimed to improve opioid use treatment outcomes. However, Medicaid does not cover all forms of MOUD, particularly methadone, in many states. We examined associations between medication for opioid use disorder (MOUD) plans and substance use treatment discharge reason (e.g., completed treatment, dropped out of treatment) as well as treatment retention (i.e., length of stay), and estimated whether these relationships were modified by state Medicaid methadone coverage. Data from the 2016 Treatment Episode Data Set for Discharges (TEDS-D) included 152,196 opioid-related treatment episodes from 47 states using relative risk regression with state clustering. Discharges involving MOUD had higher treatment retention for >180 days (aRR: 1.60, 95% CI: 1.29, 1.99) and >365 days (aRR: 2.64, 95% CI: 2.00, 3.49) but lower treatment completion (aRR: 0.46, 95% CI: 0.38, 0.57). There was no evidence that state Medicaid methadone coverage modified any of these relationships. Focusing on treatment completion alone may obscure health benefits associated with longer MOUD treatment retention.

Dual mental health diagnoses predict the receipt of medication-assisted opioid treatment: Associations moderated by state Medicaid expansion status, race/ethnicity and gender, and year

BACKGROUND

Mental health diagnoses (MHD) are common among those with opioid use disorders (OUD). Methadone/buprenorphine are effective medication-assisted treatment (MAT) strategies; however, treatment receipt is low among those with dual MHDs. Medicaid expansions have broadly increased access to OUD and mental health services over time, but MAT uptake may vary depending on multiple factors, including MHD status, state Medicaid expansion decisions, and race/ethnicity and gender. Examining clinical and policy approaches to promoting MAT uptake may improve services among marginalized groups.

METHODS

MAT treatment discharges were identified using the Treatment Episodes Dataset-Discharges (TEDS-D; 2014-2017) (n = 1,400,808). We used multivariate logistic regression to model MAT receipt using interactions and adjusted for several potential confounders.

RESULTS

Nearly one-third of OUD treatment discharges received MAT. Dual MHDs in both expansion and non-expansion states were positively associated with MAT uptake over time. Dual MHDs were negatively associated with MAT receipt only among American Indian/Alaska Native women residing in Medicaid expansion states (aOR = 0.58, 95 % CI = 0.52-0.66, p < 0.0001).

CONCLUSION

Disparities in MAT utilization are nuanced and vary widely depending on dual MHD status, Medicaid expansion, and race/ethnicity/gender. Medicaid is beneficial but not a universal treatment panacea. Clinical decisions to initiate MAT are dependent on multiple factors and should be tailored to meet the needs of high-risk, historically disadvantaged clients.

Association of Racial/Ethnic Segregation With Treatment Capacity for Opioid Use Disorder in Counties in the United States

IMPORTANCE

Treatment with methadone or buprenorphine is the current standard of care for opioid use disorder. Given the paucity of research identifying which patients will respond best to which medication, both medications should be accessible to all patients so that patients can determine which works best for them. However, given differences in the historical contexts of their initial implementation, access to each of these medications may vary along racial/ethnic lines.

OBJECTIVE

To examine the extent to which capacity to provide methadone and buprenorphine vary with measures of racial/ethnic segregation.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study included all counties and county-equivalent divisions in the US in 2016. Data on racial/ethnic population distribution were derived from the American Community Survey, and data on locations of facilities providing methadone and buprenorphine were obtained from Substance Abuse and Mental Health Services Administration databases. Data were analyzed from August 22, 2018, to September 11, 2019.

EXPOSURES

Two county-level measures of racial/ethnic segregation, including dissimilarity (representing the proportion of African American or Hispanic/Latino residents who would need to move census tracts to achieve a uniform spatial distribution of the population by race/ethnicity) and interaction (representing the probability that an African American or Hispanic/Latino resident will interact with a white resident and vice versa, assuming random mixing across census tracts).

MAIN OUTCOMES AND MEASURES

County-level capacity to provide methadone or buprenorphine, defined as the number of facilities providing a medication per 100 000 population.

RESULTS

Among 3142 US counties, there were 1698 facilities providing methadone (0.6 facilities per 100 000 population) and 18 868 facilities providing buprenorphine (5.9 facilities per 100 000 population). Each 1% decrease in probability of interaction of an African American resident with a white resident was associated with 0.6 more facilities providing methadone per 100 000 population. Similarly, each 1% decrease in probability of interaction of a Hispanic/Latino resident with a white resident was associated with 0.3 more facilities providing methadone per 100 000 population. Each 1% decrease in the probability of interaction of a white resident with an African American resident was associated with 8.17 more facilities providing buprenorphine per 100 000 population. Similarly, each 1% decrease in the probability of interaction of a white resident with a Hispanic/Latino resident was associated with 1.61 more facilities providing buprenorphine per 100 000 population.

CONCLUSIONS AND RELEVANCE

These findings suggest that the racial/ethnic composition of a community was associated with which medications residents would likely be able to access when seeking treatment for opioid use disorder. Reforms to existing regulations governing the provisions of these medications are needed to ensure that both medications are equally accessible to all.

Availability of Medications for the Treatment of Alcohol and Opioid Use Disorder in the USA

Despite high mortality rates due to opioid overdose and excessive alcohol consumption, medications for the treatment of alcohol and opioid use disorder have not been widely used in the USA. This paper provides an overview of the literature on the availability of alcohol and opioid used disorder medications in the specialty substance use disorder treatment system, other treatment settings and systems, and among providers with a federal waiver to prescribe buprenorphine. We also present the most current data on the availability of alcohol and opioid use disorder medications in the USA. These estimates show steady growth in availability of opioid use disorder medications over the past decade and a decline in availability of alcohol use disorder medications. However, overall use of medications in the USA remains low. In 2017, only 16.3% of specialty treatment programs offered any single medication for alcohol use disorder treatment and 35.5% offered any single medication for opioid use disorder treatment. Availability of buprenorphine-waivered providers has increased significantly since 2002. However, geographic disparities in access to buprenorphine remain. Some of the most promising strategies to increase availability of alcohol and opioid use disorder medications include the following: incorporating substance use disorder training in healthcare education programs, educating the substance use disorder workforce about the benefits of medication treatment, reducing stigma surrounding the use of medications, implementing medications in primary care settings, implementing integrated care models, revising regulations on methadone and buprenorphine, improving health insurance coverage of medications, and developing novel medications for the treatment of substance use disorder.

Do electronic health record prompts increase take-home naloxone administration for emergency department patients after an opioid overdose?

BACKGROUND AND AIMS

Distribution of take-home naloxone (THN) to emergency department (ED) patients who have survived an opioid overdose (OD) could reduce future opioid mortality, but is not commonly performed. We examined whether electronic health record (EHR) prompts provided to ED physicians when discharging a patient after an OD could improve THN distribution.

DESIGN

Interrupted time-series analysis to compare the percentage of OD patients who received THN during the 11 months before and after implementation of an EHR prompt on 18 June 2017.

SETTING AND PARTICIPANTS

A total of 3492 adult patients with diagnoses of OD discharged from nine EDs in a single health system in Western Pennsylvania from July 2016 to April 2018.

INTERVENTION AND COMPARATOR

The EHR prompt was triggered by the presence of specific terms in the nurse's initial assessment note. The EHR displayed a pop-up window during the ED physician discharge process asking the physician to consider prescribing or providing naloxone to the patient. The comparator was 'no EHR prompt'.

MEASUREMENTS

Measurements were based on standard criteria from ICD diagnostic codes and chief complaint keywords.

FINDINGS

In July 2016, 16.3% [95% confidence interval (CI) = 14.0, 18.5] of OD patients received THN, which decreased every month through June 2017 by 1.2% (P < 0.0001, 95% CI = 0.8,1.7). For each month post-EHR prompt there was an increase of 2.8% of OD patients receiving THN (P < 0.001, 95% CI = 2.0, 3.5). No increases occurred in the ED with the highest pre-EHR prompt THN distribution. Rates of THN distribution varied by patient age and race prior to, but not after, implementation of EHR prompts.

CONCLUSIONS

Electronic health record prompts are associated with increased take-home naloxone distribution for emergency department patients discharged after opioid overdoses.

Who receives naloxone from emergency medical services? Characteristics of calls and recent trends

Background: With the rapid rise in opioid overdose-related deaths, state policy makers have expanded policies to increase the use of naloxone by emergency medical services (EMS). However, little is known about changes in EMS naloxone administration in the context of continued worsening of the opioid crisis and efforts to increase use of naloxone. This study examines trends in patient demographics and EMS response characteristics over time and by county urbanicity. Methods: We used data from the 2013-2016 National EMS Information System to examine trends in patient demographics and EMS response characteristics for 911-initiated incidents that resulted in EMS naloxone administration. We also assessed temporal, regional, and urban-rural variation in per capita rates of EMS naloxone administrations compared with per capita rates of opioid-related overdose deaths. Results: From 2013 to 2016, naloxone administrations increasingly involved young adults and occurred in public settings. Particularly in urban counties, there were modest but significant increases in the percentage of individuals who refused subsequent treatment, were treated and released, and received multiple administrations of naloxone before and after arrival of EMS personnel. Over the 4-year period, EMS naloxone administrations per capita increased at a faster rate than opioid-related overdose deaths across urban, suburban, and rural counties. Although national rates of naloxone administration were consistently higher in suburban counties, these trends varied across U.S. Census Regions, with the highest rates of suburban administration occurring in the South. Conclusions: Naloxone administration rates increased more quickly than opioid deaths across all levels of county urbanicity, but increases in the percentage of individuals requiring multiple doses and refusing subsequent care require further attention.

How Might Maternal Poverty Impact the Course of Neonatal Opioid Withdrawal Syndrome?

: Neonatal Opioid Withdrawal Syndrome (NOWS) is an increasing problem in the midst of the current opioid epidemic, frequently associated with pharmacologic treatment and prolonged hospitalizations. NOWS is a highly variable condition with many clinical and genetic variables contributing to the clinical course. Social variables such as maternal poverty remain understudied. In this commentary, we review one of the first studies of the association between maternal poverty and infant hospital length of stay in infants with NOWS. This has important implications for designing population level interventions to improve NOWS outcomes.

Medication-Assisted Treatment Use Among Pregnant Women With Opioid Use Disorder

OBJECTIVE

To evaluate temporal trends in medication-assisted treatment use among pregnant women with opioid use disorder.

METHODS

We conducted a retrospective cohort study using Pennsylvania Medicaid administrative data. Trends in medication-assisted treatment use, opioid pharmacotherapy (methadone and buprenorphine) and behavioral health counselling, were calculated using pharmacy records and procedure codes. Cochrane-Armitage tests evaluated linear trends in characteristics of pregnant women using methadone compared with buprenorphine.

RESULTS

In total, we evaluated 12,587 pregnancies among 10,741 women with opioid use disorder who had a live birth between 2009 and 2015. Across all years, 44.1% of pregnant women received no opioid pharmacotherapy, 27.1% used buprenorphine, and 28.8% methadone. Fewer than half of women had any behavioral health counseling during pregnancy. The adjusted prevalence of methadone use declined from 31.6% (95% CI 29.3-33.9%) in 2009 to 25.2% (95% CI 23.3-27.1%) in 2015, whereas the adjusted prevalence of buprenorphine use increased from 15.8% (95% CI 13.9-17.8%) to 30.9% (95% CI 28.8-33.0%). Greater increases in buprenorphine use were found in geographic regions with large metropolitan centers, such as the Southwest (plus 24.9%) and the Southeast (plus 12.0%), compared with largely rural regions, such as the New West (plus 5.2%). In 2015, the adjusted number of behavioral health counseling visits during pregnancy was 3.4 (95% CI 2.6-4.1) among women using buprenorphine, 4.0 (95% CI 3.3-4.7) among women who did not use pharmacotherapy, and 6.4 (95% CI 4.9-7.9) among women using methadone.

CONCLUSION

Buprenorphine use among Medicaid-enrolled pregnant women with opioid use disorder increased significantly over time, with a small concurrent decline in methadone use. Behavioral health counseling use was low, but highest among women using methadone.

The Affordable Care Act In The Heart Of The Opioid Crisis: Evidence From West Virginia

West Virginia is at the epicenter of a national opioid crisis, with a 2016 fatal opioid overdose rate of 43.4 per 100,000 population-more than triple the US average. We used claims data for 2014-16 to examine trends in treatment for opioid use disorder (OUD) among people enrolled in the West Virginia Medicaid expansion program under the Affordable Care Act. Expanding Medicaid could provide services to populations that may previously have had limited access to OUD treatment. We thus sought to understand trends over time in OUD diagnosis and treatment, especially with medications. About 5.5 percent of all enrollees were diagnosed with OUD per year, and the monthly prevalence of OUD diagnoses nearly tripled during this three-year period. The ratio of people filling buprenorphine to the number diagnosed with OUD was around one-third in early 2014, increasing to more than 75 percent by late 2016. Mean annual duration of filled buprenorphine increased from 161 days in 2014 to 185 days in 2016, and most people filling buprenorphine also received counseling and drug testing during the study period. The growing use of medication treatment for OUD in the West Virginia Medicaid expansion population provides an opportunity to reduce overdose deaths.
