Racial/ethnic disparities in the use of medications for opioid use disorder (MOUD) and their effects on residential drug treatment outcomes in the US

Knowledge, experiences, and perceptions of medications for opioid use disorder among Black Kentuckians

BACKGROUND

Opioid overdoses have continued to increase at higher rates among Black Americans compared to people from other racial groups. Despite demonstrated effectiveness of MOUD in reducing risk of opioid overdose, Black Americans face decreased access to and uptake of MOUD. The current study aimed to examine the knowledge, perceptions, and experiences with MOUD among a sample of Black adults who use prescription opioids nonmedically in order to inform tailored efforts to improve MOUD uptake.

METHODS

Data were derived from a larger study assessing cultural and structural influences on drug use and drug treatment among people who use prescription opioids nonmedically. Semi-structured qualitative interviews were conducted with 34 Black men and women across four generational cohorts: born 1955-1969; 1970-1979; 1980-1994; and 1995-2001. Participant responses were analyzed using thematic analysis.

RESULTS

Nearly half of participants (44.1%) reported no knowledge or experience with MOUD. Among participants who had any knowledge about MOUD, four major themes regarding their perceptions emerged: MOUD Helps with Recovery; Not Needed for Level of Drug Use; Side Effects and Withdrawal; Equivalence with Illicit Drug Use. The majority reported negative perceptions of MOUD (52.6%), and the youngest cohort (born 1995-2001) had a higher proportion of negative perceptions (80%) relative to other age cohorts (born 1980-1994: 50%; 1970-1979: 75%; 1955-1969: 16.6%).

DISCUSSION

Findings indicate a significant knowledge gap and clear points of intervention for improving MOUD uptake. Interventions to improve communication of health information in ways that are culturally relevant and tailored by age group can be used in conjunction with efforts to improve MOUD access among Black individuals who use opioids nonmedically.

Correlates of Current Methamphetamine Use and Opioid Co-Use Among Latina Women in a Low-Income Community

Using data from Proyecto SALTO, a 15-year follow-up study of a cohort of Mexican American women in a low-income community in San Antonio, Texas, this study examines emerging patterns of current methamphetamine (MA) use, including opioid co-use, among this understudied population. A bivariate analysis compared individuals with and without current MA use and identified sociodemographic correlates and co-occurring mental health and substance use. A secondary analysis compared those with current MA use, opioid use, and concurrent MA and opioid use. Nineteen percent of the sample had current MA use. MA use was associated with having a lower income (OR = 7.04-1.93, SE = 1.59-5.46), residential instability (OR = 5.19, SE = 1.99), and suicidal ideation (OR = 2.62, SE = 0.93). Participants with MA use had more than four times the odds of using opioids than those without MA use. Women with concurrent MA and opioid use differed in sociodemographics and behavioral risks compared to those with only MA or only opioid use. These findings explore the social, mental health, and structural inequities that exacerbate risks and harms associated with high-risk substance use among marginalized Latino populations. Prevention and intervention strategies should adopt a holistic approach that considers and addresses polysubstance use, mental health, and the sociocultural contexts in which individuals live.

Worsening trends in the frequency of methamphetamine and other stimulant use between treatment admission and discharge

BACKGROUND

Treatment for methamphetamine and other stimulants can be effective but treatment attrition and continued use are very high. Abstinence is the conventional outcome used to evaluate treatment success, but defining treatment success in this way misses opportunities to promote improved health even when abstinence is not achieved. Reducing methamphetamine and stimulant use without abstinence is associated with many positive outcomes. However, little is known about drug use patterns during treatment or trends in use over time.

METHODS

We used the Treatment Episode Dataset-Discharges (TEDS-D) to identify treatment episodes that had a stimulant drug indicated as the primary substance of use (2017-2021; N=251,841; methamphetamine, cocaine, other amphetamines, or other stimulants). Our outcome was the change in the frequency of drug use between admission and discharge (decreased use with abstinence, decreased use without abstinence, increased use). We used multiple logistic regression to model a change in drug use frequency, predicted by year, stimulant type, and their interaction.

RESULTS

Nearly two-thirds of the sample (60 %) had methamphetamine indicated as the primary stimulant of use. There was a decrease in the predicted rate of abstinence over time and worsening trends were strongest among those using methamphetamine. Daily and periodic drug use at both admission and discharge (no change in use) became worse over time, particularly for those using methamphetamine.

CONCLUSION

Treatment outcomes worsened over time and declined fastest among those reporting methamphetamine. Abstinence was rare and most treatment clients did not change their drug use behavior. We recommend a renewed focus on evidence-based harm reduction while the nation's treatment systems continue grappling with the stimulant crises.

Latine perspectives on the impact of family, perceptions of medication, health systems, incarceration, and housing on accessing opioid agonist therapy: A thematic analysis

INTRODUCTION

Opioid-related overdose deaths rates among Latine individuals are increasing rapidly and, in Massachusetts, have exceeded rates among non-Hispanic White individuals. Yet Latine individuals are less likely to receive opioid agonist therapies (OAT) methadone and buprenorphine, which have been demonstrated to prevent opioid deaths. Amid climbing Latine overdose rates, we lack qualitative data from Spanish-speaking people who use opioids about their views on and access to OAT. In this paper, we sought to assess variables affecting Latine individuals' initiation of OAT.

METHODS

We conducted 21 semi-structured interviews - half in Spanish - with Latine-identifying individuals recruited from four locations-three residential treatment sites and one city shelter-in Boston offering services to people who use drugs. We utilized thematic analysis to identify barriers and facilitators to starting and continuing OAT.

RESULTS

The following themes - which cut across individual-, interpersonal-, and systems-level variables - emerged as core considerations shaping Latine participants' OAT engagement: (1) family, (2) medication desirability and accessibility, (3) health care resources, (4) housing stability, and (5) incarceration. First, family members were prominent interpersonal influences on participants' treatment decisions. For some participants, family introduced participants to opioids at young ages and later supported them in recovery. Second, engagement with OAT was shaped by individual-level opinions on the medications as well as by systems-level experiences with trying to access the medications. Participants identified benefits and drawbacks of methadone versus buprenorphine, with greater access difficulties for methadone. Third, the health care setting in Boston provided notable systems-level facilitators to OAT access, including outreach workers, Medicaid, and Spanish-speaking providers. Fourth, housing instability impeded some from accessing OAT while motivating others to initiate the medications. Finally, incarceration created systems-level barriers to OAT engagement. Most participants had been incarcerated in jail or prison but did not have access to OAT during incarceration or during their transition back to the community.

CONCLUSIONS

Approaches to increase OAT engagement among Latine individuals should consider integrating family into recovery pathways, tailoring information in Spanish, developing bilingual/bicultural staffing, ensuring supportive insurance coverage systems, addressing housing needs, and making OAT available for individuals involved in the legal system.

Evidence-based treatment for opioid use disorder is widely unavailable and often discouraged by providers of residential substance use services in North Carolina

INTRODUCTION

Opioid agonist treatment (OAT) is the only treatment for opioid use disorder (OUD) proven to reduce overdose mortality, yet access to this evidence-based treatment remains poor. The purpose of this cross-sectional audit study was to assess OAT availability at residential substance use services in North Carolina.

METHODS

We conducted a state-wide inventory of residential substance use service providers in North Carolina and subsequently called all providers identified, posing as uninsured persons who use heroin, seeking treatment services. Program characteristics, as reported in phone calls, were systematically recorded. We used Fisher's exact tests to assess what program characteristics were associated with OAT availability and with staff making discouraging comments about OAT. We used unsupervised agglomerative clustering to identify facilities with similar characteristics.

RESULTS

Of the 94 treatment providers identified, we successfully contacted and collected data from 66. Of those, only 7 (10.6 %) provide OAT on site; an additional 9 (13.6 %) allow OAT through an outside or community-based prescriber. Only 8 (12.1 %) providers were licensed to provide residential substance use treatment. Staff from 33 (50.0 %) providers made negative, discouraging, or stigmatizing remarks about OAT-for example, that OAT substitutes one addiction for another or does not constitute "true recovery." OAT availability was positively associated with a provider holding a state license for any substance use-related service (41.9 % vs 8.6 %, p = 0.002) and offering 12-step programming (36.1 % vs. 10/0 %, p = 0.020). OAT availability was negatively associated with faith-based programming (6.1 % vs 42.4 %, p = 0.001), dress codes (5.3 % vs 50.0 %, p < 0.001), and mandates that residents work in a provider-owned and -operated commercial enterprise (5.0 % vs 32.6 %, p = 0.026). Cluster analysis revealed that the most common (n = 21) type of service provider in North Carolina is an unlicensed, faith-based organization that prohibits OAT, imposes a dress code, and mandates that residents work, often in provider-owned and -operated commercial enterprises.

CONCLUSION

Evidence-based treatments for OUD are largely unavailable at providers of residential substance use services in North Carolina. The prohibition of OAT occurs most often among providers who are unlicensed and impose labor and/or 12-step mandates on residents. Changes to state licensure requirements and exemptions may help improve OAT availability.

Supporting positive parenting among pregnant people in recovery from opioid use disorder: Introducing family check‐up–prenatal

Opioid use disorder (OUD) among pregnant people has increased dramatically during the opioid epidemic, affecting a significant number of families with young children. Parents with OUD commonly face significant challenges as they are often balancing the stress of caring for young children with maintaining recovery and co-occurring psychosocial challenges (e.g., mental health, low social support). Toward designing interventions to address parenting needs among parents with OUD, we conducted a mixed-methods study to understand the acceptability of receiving parenting support prenatally among pregnant people with OUD residing in the United States. Semi-structured interviews were conducted among 18 pregnant and early postpartum people recruited from a substance use treatment program specializing in the care of pregnant and parenting populations. Among all participants, a prenatal parenting program that comprehensively addresses recovery, parenting, and wellbeing was found to be widely acceptable. Regarding content most desirable within a parenting intervention, participants indicated an interest in breastfeeding, caring for newborns with in-utero opioid exposure, parent-infant bonding, infant soothing techniques, their own wellbeing/mental health, and parenting skills. We introduce a prenatal adaptation of the well-established Family Check-up parenting intervention as a novel, prenatal intervention to prevent negative outcomes for caregivers in recovery and their children.

Racial and Ethnic Disparities in Take-Home Methadone Use for Medicare Beneficiaries With Opioid Use Disorder

This cross-sectional study examines racial and ethnic disparities in take-home methadone use among Medicare beneficiaries with opioid use disorder following the Substance Abuse and Mental Health Services Administration’s policy change in March 2020.

Are gaps in rates of retention on buprenorphine for treatment of opioid use disorder closing among veterans across different races and ethnicities? A retrospective cohort study

INTRODUCTION

The U.S. Veterans Health Administration has undertaken several initiatives to improve veterans' access to and retention on buprenorphine because it prevents overdose and reduces drug-related morbidity. We aimed to determine whether improvements in retention duration over time was equitable across veterans of different races and ethnicities.

METHODS

This retrospective cohort study was conducted among veterans who initiated buprenorphine from federal fiscal years (FY) 2006 to 2020 after diagnosis of opioid use disorder. Using an accelerated failure time model, we estimated the association between time to buprenorphine discontinuation and FY of initiation, race and ethnicity, and other control covariates. We followed veterans from buprenorphine initiation until they discontinued or had a censoring event. We then estimated the predicted median days retained on buprenorphine, the average marginal effect of initiating in a later FY, the same measure by race and ethnicity, the incremental effect of the various racial and ethnic identities in contrast to non-Hispanic White, and the total change in the size of the gap over the 15 years of the study between veterans with a minoritized racial or ethnic identity compared to non-Hispanic White veterans.

RESULTS

Most of the 31,797 veterans in the sample were non-Hispanic White (74.5 %), from urban areas (83.5 %), male (92.0 %), and had significant comorbidities, most frequently anxiety disorders (51.0 %) and depression (63.0 %). Overall, 49.8 % of veterans were retained at least 180 days. The average marginal effect of FY was 7.0 days [95%CI:5.3, 8.8] but was significantly smaller among veterans identifying as Black or African American [3.2 days; 95%CI:2.4, 4.1] or Asian [3.6 days; 95%CI:1.6, 5.7] compared to veterans who identify as non-Hispanic White [7.9 days; 95%CI:5.9, 9.9]. Additional measures of change were significant for veterans identifying as Hispanic White or with two or more races.

CONCLUSION

Although buprenorphine retention in OUD treatment improved for all veterans over the 15-year study period, veterans from most minoritized racial and ethnic groups fell further behind as gains in duration on therapy accrued primarily to non-Hispanic White veterans. Targeted interventions addressing specific challenges experienced by veterans with minoritized identities are needed to close gaps in retention on buprenorphine.

The effect of a pilot brief educational intervention on preferences regarding treatments for opioid use disorder

Purpose

Negative perceptions around medications for opioid use disorder (MOUD) amongst the public could deter patients with opioid use disorder (OUD) from engaging with MOUD. Thus, we evaluated whether a brief intervention could improve preferences for MOUD in people who may or may not use opioids.

Methods

We employed a pre-post design to assess the effect of a brief educational intervention on preferences for methadone, buprenorphine, naltrexone, and non-medication treatment in an online sample of US adults stratified by race, who may or may not use opioids. Respondents ranked their preferences in OUD treatment before and after watching four one-minute educational videos about treatment options. Changes in treatment preferences were analyzed using Bhapkar's test and post hoc McNemar's tests. A binary logistic generalized estimating equation (GEE) assessed factors associated with preference between treatments.

Results

The sample had 530 responses. 194 identified as White, 173 Black, 163 Latinx. Treatment preferences changed significantly towards MOUD (p<.001). This effect was driven by changes toward buprenorphine (OR=2.38; p<.001) and away from non-medication treatment (OR=0.20; p<.001). There was no significant difference in effect by race/ethnicity. People with lower opioid familiarity were significantly more likely to change their preferences towards MOUD following the intervention.

Conclusion

Respondent preferences for MOUD increased following the intervention suggesting that brief educational interventions can change treatment preferences towards MOUD. These findings offer insights into perceptions of OUD treatment in a racially stratified sample and serve as a foundation for future educational materials that target MOUD preferences in the general public.

Access to medications for opioid use disorder for formerly incarcerated individuals during community reentry: a mini narrative review

Medications for opioid use disorder (MOUD) are especially important for formerly incarcerated individuals with opioid use disorder (OUD) and can reduce the risk of re-arrest and overdose during community reentry. Unfortunately, few formerly incarcerated individuals are able to access MOUD within the community, missing a critical tool for rehabilitation. A mini narrative review was conducted to highlight the published work that has been done to improve access to MOUD for formerly incarcerated individuals during reentry. The results yielded 15 records describing intervention evaluations, program descriptions, and research in progress. Most work is ongoing, showing promise that researchers have identified the importance of this problem. However additional research should be done to include other stakeholders and address the limitations of existing interventions and programs. Continued efforts can help ensure that formerly incarcerated individuals can safely and successfully reintegrate into society.

Racial/ethnic inequality in homelessness and drug overdose deaths in US States

PURPOSE

This study examined whether state-level racial disproportionality in homelessness is associated with racial disproportionality in overdose mortality.

METHODS

Counts of individuals experiencing homelessness (2015-2017; by state and racial/ethnic group) were obtained from the US Department of Housing and Urban Development; population estimates and counts of drug overdose deaths (2018-2021; by state and racial/ethnic group) were obtained from the National Center for Health Statistics. Homelessness and overdose mortality disproportionality scores were calculated to indicate the extent to which each racial group was over- or under- represented among those experiencing homelessness, or among overdose deaths, respectively (relative to each racial group's proportional share in the general population). For each racial group examined, ordinary least squares regression models with robust standard errors (SEs) examined associations between state-level disproportionality in homelessness and disproportionality in overdose mortality, adjusting for percent aged 18-64 and US Census Region, as well as disproportionality in educational attainment and unemployment.

RESULTS

State-level racial disproportionality in homelessness was significantly and positively associated with racial disproportionality in overdose mortality for Black (b = 0.16 [SE = 0.05]; p < .01), American Indian/Alaska Native (b = 0.71 [SE = 0.23]; p < .01), and Hispanic populations (b = 0.17 [SE = 0.05]; p < .01), in models adjusting for region and percent aged 18-64. The significant positive associations in these three populations persisted after adjusting for educational attainment disproportionality, yet the association was no longer significant in the Black population after adjusting for unemployment disproportionality.

CONCLUSION

States with the highest levels of racial/ethnic minority overrepresentation in homelessness generally also had relatively higher levels of racial/ethnic minority overrepresentation in overdose deaths.

Strategies to Improve Patient-Centered Care for Drug Use-Associated Infective Endocarditis: JACC Focus Seminar 2/4

Drug use-associated infective endocarditis (DUA-IE) is a major cause of illness and death for people with substance use disorder (SUD). Investigations to date have largely focused on advancing the care of patients with DUA-IE and included drug use disorder treatment, decisions about surgery, and choice of antibiotics during the period of hospitalization. Transitions from hospital to outpatient care are relatively unstudied and frequently a key factor of uncontrolled infection, continued substance use, and death. In this paper, we review the evidence supporting cross-disciplinary care for people with DUA-IE and highlight domains that need further clinician, institutional, and research investment in clinicians and institutions. We highlight best practices for treating people with DUA-IE, with a focus on addressing health disparities, meeting health-related social needs, and policy changes that can support care for people with DUA-IE in the hospital and when transitioning to the community.

Mobile treatment for opioid use disorder: Implementation of community-based, same-day medication access interventions

BACKGROUND

Medications for Opioid Use Disorder (MOUD) are lifesaving, but <20 % of individuals in the US who could benefit receive them. As part of the NIH-supported HEALing Communities Study (HCS), coalitions in several communities in Massachusetts and Ohio implemented mobile MOUD programs to overcome barriers to MOUD receipt. We defined mobile MOUD programs as units that provide same-day access to MOUD at remote sites. We aimed to (1) document the design and organizational structure of mobile programs providing same-day or next-day MOUD, and (2) explore the barriers and facilitators to implementation as well as the successes and challenges of ongoing operation.

METHODS

Program staff from five programs in two states (n = 11) participated in semi-structured interviews. Two authors conducted thematic analysis of the transcripts based on the domains of the social-ecological model and the semi-structured interview guide.

RESULTS

Mobile MOUD units sought to improve immediate access to MOUD ("Our answer is pretty much always, 'Yes, we'll get you started right here, right now,'"), advance equity ("making sure that we have staff who speak other languages, who are on the unit and have some resources that are in different languages,"), and decrease opioid overdose deaths. Salient program characteristics included diverse staff, including staff with lived experience of substance use ("She just had that personal knowledge of where we should be going"). Mobile units offered harm reduction services, broad medical services (in particular, wound care), and connection to transportation programs and incorporated consistency in service provision and telemedicine access. Implementation facilitators included trusting relationships with partner organizations (particularly pharmacies and correctional facilities), nuanced understanding of local politics, advertising, protocol flexibility, and on-unit prescriber hours. Barriers included unclear licensing requirements, staffing shortages and competing priorities for staff, funding challenges due to inconsistency in grant funding and low reimbursement ("It's not really possible that billing in and of itself is going to be able to sustain it"), and community stigma toward addiction services generally.

CONCLUSIONS

Despite organizational, community, and policy barriers, participants described mobile MOUD units as an innovative way to expand access to life-saving medications, promote equity in MOUD treatment, and overcome stigma.

Opioid Overdose Hospitalizations During COVID-19: The Experience of Pennsylvania

Objective

The COVID-19 pandemic placed extreme burden on hospitals, while opioid overdose is another challenging public health issue. This study aimed to examine the trends and outcomes of opioid overdose hospitalizations in Pennsylvania during 2018 to 2021.

Design

We identified opioid overdose hospitalizations in the state of Pennsylvania using the state-wide hospital discharge database (PHC4) 2018 to 2021. We examined the number of opioid overdose hospitalizations, the corresponding mortality and discharges against medical advice comparing the pre-COVID period (2018-2019) and the COVID period (2020-2021). We also assessed what patient and hospital characteristics were associated with in-hospital death or leaving against medical advice.

Results

A total of 13 446 opioid-related hospitalizations were identified in 2018 to 2021. Compared to pre-pandemic, a higher percentage of cases involving synthetics (17.0%vs 10.3%, P < .0001) were observed during COVID. After controlling for covariates, there was no significant difference in opioid overdose in-hospital deaths in the years 2020 to 2021 compared to 2018 to 2019 (OR = 0.846, 95% CI: 0.71-1.01, P = .065). The COVID period was significantly associated with more leaving against medical advice compared to years 2018 to 2019 (OR = 1.265, 95% CI: 1.11-1.44, P = .0003). Compared to commercial insurance, Medicaid insurance was associated with higher odds of both in-hospital death (OR = 1.383, 95% CI: 1.06-1.81, P = .0176) and leaving against medical advice (OR = 1.903, 95% CI: 1.56-2.33, P < .0001).

Conclusion

There were no substantial changes in the number of overall opioid overdose cases and deaths at hospitals following the outbreak of COVID-19 in Pennsylvania. This observation suggests that an increased number of patients may have succumbed to overdoses outside of hospital settings, possibly due to a higher severity of overdoses. Further, we found that patients were more likely to leave against medical advice during the COVID-19 pandemic.

Disparities in fatal and non-fatal opioid-involved overdoses among middle-aged non-Hispanic Black Men and Women

The gap in fatal opioid overdose rates has been closing between non-Hispanic Black and non-Hispanic White individuals. The rising opioid-involved mortality rates among non-Hispanic Black adults has been identified by SAMHSA as a critical public health issue. However, further research is needed that utilizes comprehensive surveillance data on both fatal and non-fatal opioid-involved overdoses to better assess the changing trends and evaluate factors contributing to changing disparities. We conducted an analysis of medical examiner and hospital data for years 2016-2021 from the largest county in Illinois (Cook) to (1) evaluate disparities in non-fatal and fatal opioid-involved overdoses between middle-aged non-Hispanic Black adults and Black adults of other age groups stratified by sex, (2) to assess if disparities exist across middle-aged adults of different race-ethnicities specifically non-Hispanic White and Hispanic-Latino adults, and (3) evaluate factors contributing to the disparities. Fatal opioid overdose rates among middle-aged Black men 45-64 years old were on average 5.3 times higher than Black men of other age groups, and 6.2 times higher than middle-aged non-Black men. Similarly, fatal opioid overdose rates among middle-aged Black women were on average 5.0 times higher than Black women of other age groups, and 4.9 times higher than middle-aged non-Black women. Hospital utilization rates for opioid-involved overdoses showed similar disparities between age groups and race-ethnicities. Findings indicate that stark disparities in rates of opioid-involved overdoses among middle-aged Black men and women are likely attributed to exposure to more lethal opioids, drug variability in local markets, differences in concurrent drug exposures, and lower access to harm reduction, emergent and preventative health services.

Opioid-Related Trends in Active Duty Service Members During the Coronavirus Disease 2019 Pandemic

INTRODUCTION

The USA is experiencing an opioid epidemic. Active duty service members (ADSMs) are at risk for opioid use disorder (OUD). The Coronavirus disease 2019 (COVID-19) pandemic has disrupted health care and introduced additional stressors.

METHODS

The Military Healthcare System Data Repository was used to evaluate changes in diagnosis of OUD, medications for OUD (MOUD), opioid overdose (OD), and opioid rescue medication. ADSMs ages 18-45 years enrolled in the Military Healthcare System between February 2019 and April 2022 were included. Joinpoint Trend Analysis Software calculated the average monthly percent change over the study period, whereas Poisson regression compared outcomes over three COVID-19 periods: Pre-lockdown (pre-COVID-19 period 0) (February 2019-February 2020), early pandemic until ADSM vaccination initiation (COVID-19 period 1 [CP1]) (March 2020-November 2020), and late pandemic post-vaccination initiation (COVID-19 period 2 [CP2]) (December 2020-April 2022).

RESULTS

A total of 1.86 million eligible ADSMs received care over the study period. Diagnoses of OUD decreased 1.4% monthly, MOUD decreased 0.6% monthly, diagnoses of opioid OD did not change, and opioid rescue medication increased 8.5% monthly.Diagnoses of OUD decreased in both COVID-19 time periods: CP1 and CP2: Rate ratio (RR) = 0.74 (95% CI, 0.68-0.79) and RR = 0.72 (95% CI, 0.67-0.76), respectively. MOUD decreased in both CP1 and CP2: RR = 0.77 (95% CI, 0.68-0.88) and RR = 0.86 (95% CI, 0.78-0.96), respectively. Adjusted rates for diagnoses of opioid OD did not vary in either COVID-19 time period. Opioid rescue medication prescriptions increased in CP1 and CP2: RR = 1.09 (95% CI, 1.02-1.15) and RR = 6.02 (95% CI, 5.77-6.28), respectively.

CONCLUSIONS

Rates of OUD and MOUD decreased, whereas rates of opioid rescue medication increased during the study period. Opioid OD rates did not significantly change in this study. Changes in the DoD policy may be affecting rates with greater effect than COVID-19 pandemic effects.

Inequities in the treatment of opioid use disorder: A scoping review

BACKGROUND

Given the lack of access to evidenced-based OUD treatment and the corresponding overdose crisis, researchers must evaluate and report health care inequities involving the treatment of OUD. Additionally, clinicians should be aware of these inequities in the treatment of patients.

METHODS

We carried out a scoping review of the literature regarding health inequities in treatment for OUD in July 2022. The study team retrieved articles published between 2016 and 2021 from MEDLINE and Ovid Embase. After authors received training, screening and data extraction were performed in masked, duplicate fashion. The team screened a total of 3673 titles and abstracts, followed by 172 articles for full-text review. The inequities that we examined were race/ethnicity, sex or gender, income, under-resourced/rural, occupational status, education level, and LGBTQ+. We used Stata 17.0 (StataCorp, LLC, College Station, TX) to summarize data and statistics of the studies within our sample.

RESULTS

A total of 44 studies evaluating inequities in OUD treatment met inclusion criteria. The most common inequity that studies examined was race/ethnicity (34/44 [77.27 %] studies), followed by under-resourced/rural (19/44 [43.18 %] studies), and sex or gender (18/44 [40.91 %] studies). LGBTQ+ (0/44 [0.0 %] studies) was not reported in the included studies. Our results indicate that many historically marginalized populations experience inequities related to access and outcomes in OUD treatment. The included studies in our scoping review occasionally demonstrated inconsistent findings.

CONCLUSIONS

Gaps exist within the literature on health inequities in treatment for OUD. The most examined inequities were race/ethnicity, under-resourced/rural and sex or gender, while studies did not examine LGBTQ+ status. Future research should aim to advance and supplement literature investigating health inequities in OUD treatment to ensure inclusive, patient-centered care.

Racial Inequality in Receipt of Medications for Opioid Use Disorder

BACKGROUND

Since 2010, Black persons in the United States have had a greater increase in opioid overdose-related mortality than other groups, but national-level evidence characterizing racial and ethnic disparities in the use of medications for opioid use disorder (OUD) is limited.

METHODS

We used Medicare claims data from the 2016-2019 period for a random 40% sample of fee-for-service beneficiaries who were Black, Hispanic, or White; were eligible for Medicare owing to disability; and had an index event related to OUD (nonfatal overdose treated in an emergency department or inpatient setting, hospitalization with injection drug use-related infection, or inpatient or residential rehabilitation or detoxification care). We measured the receipt of medications to treat OUD (buprenorphine, naltrexone, and naloxone), the receipt of high-risk medications (opioid analgesics and benzodiazepines), and health care utilization, all in the 180 days after the index event. We estimated differences in outcomes according to race and ethnic group with adjustment for beneficiary age, sex, index event, count of chronic coexisting conditions, and state of residence.

RESULTS

We identified 25,904 OUD-related index events among 23,370 beneficiaries, with 3937 events (15.2%) occurring among Black patients, 2105 (8.1%) among Hispanic patients, and 19,862 (76.7%) among White patients. In the 180 days after the index event, patients received buprenorphine after 12.7% of events among Black patients, after 18.7% of those among Hispanic patients, and after 23.3% of those among White patients; patients received naloxone after 14.4%, 20.7%, and 22.9%, respectively; and patients received benzodiazepines after 23.4%, 29.6%, and 37.1%, respectively. Racial differences in the receipt of medications to treat OUD did not change appreciably from 2016 to 2019 (buprenorphine receipt: after 9.1% of index events among Black patients vs. 21.6% of those among White patients in 2016, and after 14.1% vs. 25.5% in 2019). In all study groups, patients had multiple ambulatory visits in the 180 days after the index event (mean number of visits, 6.6 after events among Black patients, 6.7 after events among Hispanic patients, and 7.6 after events among White patients).

CONCLUSIONS

Racial and ethnic differences in the receipt of medications to treat OUD after an index event related to this disorder among patients with disability were substantial and did not change over time. The high incidence of ambulatory visits in all groups showed that disparities persisted despite frequent health care contact.

The interaction of race and age in methadone treatment retention outcomes: A single-center analysis

OBJECTIVES

Early treatment drop-out is due to the unique interplay of the individual and their context, and is associated with overdose death. The objective of this project was to determine if age or race is associated with 6-month treatment retention outcome differences at a single-center opioid treatment program.

METHODS

The study team performed a retrospective administrative database study from January 2014 to January 2017 using admission data with age and race as predictors of 6-month treatment retention outcomes.

RESULTS

Of the 457 admissions, 114 were under the age of 30; however, only 4 % of these young adults were Black, Indigenous, and/or People of Color (BIPOC). While retention for BIPOC patients (62 %) was slightly higher than for White patients (57 %), this difference did not reach traditional levels of significance.

CONCLUSIONS

Once BIPOC enter treatment, their treatment retention is similar to their White counterparts. Young adult BIPOC were less represented in the admission data, but treatment retention across racial groups was similar. An urgent need exists to determine the barriers and facilitators to treatment access among BIPOC young adults.

Community-, network-, and individual-level predictors of uptake of medication for opioid use disorder among young people who inject drugs and their networks: A multilevel analysis

BACKGROUND

Opioid use has been increasing at alarming rates over the past 15 years, yet uptake of medication for opioid use disorder (MOUD) remains low. Much of the research on individual characteristics predicting MOUD uptake is equivocal, and there is a dearth of research on setting-level and network-level characteristics that predict MOUD uptake. Towards a more holistic, multilevel understanding, we explore individual-level, network-level, and community-level characteristics associated with MOUD uptake.

METHODS

Baseline data from a longitudinal study of young people who inject drugs and their injection and support network members living in Chicago (N = 165) was used to conduct cross-sectional multilevel logistic regression analyses to examine associations between MOUD uptake and a set of potential predictors at the individual-, network-, and community-levels that were chosen based on theoretical relevance or support from previous empirical studies.

RESULTS

Stigma at both the individual and community levels was significantly associated with MOUD uptake (though in different directions). Greater individual-level stigma was associated with a higher likelihood of MOUD uptake, while having a more normatively stigmatizing community environment was associated with a lower likelihood of MOUD uptake. Using heroin and cocaine simultaneously and having a larger support network were associated with a greater likelihood of MOUD uptake.

CONCLUSIONS

The present study's holistic, multilevel approach identified three individual-level characteristics, one network-level characteristic, and one community-level characteristic associated with MOUD uptake. However, more research is needed examining multilevel predictors, to help with developing interventions addressing barriers to MOUD use at multiple levels of influence.

An evaluation of the association between specific post-overdose care services in emergency departments and subsequent treatment engagement

Objective

The objective of this study was to estimate the association between receipt of specific post-overdose care services in the emergency department (ED) and subsequent engagement in treatment for opioid use disorder (OUD) after discharge.

Methods

This was a retrospective cohort study of Rhode Island residents treated at 1 of 4 EDs for opioid overdose who were not engaged in OUD treatment and were discharged home (May 2016-April 2021). Electronic health record data were used to identify ED services received, and state administrative data were used to define subsequent engagement in OUD treatment within 30 days. Multivariable conditional logistic regression was used to estimate the association between ED services received and subsequent treatment engagement.

Results

Overall, 1008 people not engaged in OUD treatment were treated at study EDs for opioid overdose and discharged home, of whom 146 (14%) subsequently engaged in OUD treatment within 30 days. Most patients were aged 25 to 44 years (59%) and non-Hispanic White (69%). Receipt of behavioral counseling in the ED (adjusted odds ratio [aOR] = 1.79, 95% confidence interval [CI] = 1.18-2.71) and initiation of buprenorphine treatment in/from the ED (aOR = 5.86, 95% CI = 2.70-12.71) were associated with treatment engagement. Receipt of a take-home naloxone kit or naloxone prescription and referral to treatment at discharge were not associated with treatment engagement. Overall, 49% of patients received behavioral counseling in the ED, and 3% initiated buprenorphine in/from the ED.

Conclusion

Strategies for increasing provision of behavioral counseling and initiation of buprenorphine in the ED may be useful for improving subsequent engagement in OUD treatment after discharge.

Estimating the impact of the COVID-19 pandemic on rising trends in drug overdose mortality in the United States, 2018-2021

PURPOSE

During the COVID-19 pandemic, social and economic disruption such as social isolation, job and income losses, and increased psychological distress, may have contributed to the increase in drug-overdose mortality. This study aims to measure the impact of the pandemic on monthly trends in drug-overdose mortality in the United States.

METHODS

We used the 2018-2020 final and 2021 provisional monthly deaths from the National Vital Statistics System and monthly population estimates from the Census Bureau to compute monthly mortality rates by age, sex, and race/ethnicity. We use log-linear regression models to estimate monthly percent increases in mortality rates from January 2018 through November 2021.

RESULTS

The age-adjusted drug-overdose mortality rate among individuals aged older than or equal to 15 years increased by 30% between 2019 (70,459 deaths) and 2020 (91,536 deaths). During January 2018-November 2021, the monthly drug-overdose mortality rate increased by 2.05% per month for Blacks, 2.25% for American Indians/Alaska Natives, 1.96% for Hispanics, 1.33% for Asian/Pacific Islanders, and 0.96% for non-Hispanic Whites. Average monthly increases in mortality were most marked among those aged 15-24 and 35-44 years.

CONCLUSIONS

The COVID-19 pandemic had a substantial impact on the rising trends in drug-overdose mortality during the peak months in 2020 and 2021.

Outpatient follow-up and use of medications for opioid use disorder after residential treatment among Medicaid enrollees in 10 states

BACKGROUND

Follow-up after residential treatment is considered best practice in supporting patients with opioid use disorder (OUD) in their recovery. Yet, little is known about rates of follow-up after discharge. The objective of this analysis was to measure rates of follow-up and use of medications for OUD (MOUD) after residential treatment among Medicaid enrollees in 10 states, and to understand the enrollee and episode characteristics that are associated with both outcomes.

METHODS

Using a distributed research network to analyze Medicaid claims data, we estimated the likelihood of 4 outcomes occurring within 7 and 30 days post-discharge from residential treatment for OUD using multinomial logit regression: no follow-up or MOUD, follow-up visit only, MOUD only, or both follow-up and MOUD. We used meta-analysis techniques to pool state-specific estimates into global estimates.

RESULTS

We identified 90,639 episodes of residential treatment for OUD for 69,017 enrollees from 2018 to 2019. We found that 62.5% and 46.9% of episodes did not receive any follow-up or MOUD at 7 days and 30 days, respectively. In adjusted analyses, co-occurring mental health conditions, longer lengths of stay, prior receipt of MOUD or behavioral health counseling, and a recent ED visit for OUD were associated with a greater likelihood of receiving follow-up treatment including MOUD after discharge.

CONCLUSIONS

Forty-seven percent of residential treatment episodes for Medicaid enrollees are not followed by an outpatient visit or MOUD, and thus are not following best practices.

"Can we get a Black rehabilitation center"? Factors impacting the treatment experiences of Black people who use opioids

INTRODUCTION

With opioid overdose rates doubling in the state of Kentucky over the last year, the opioid crisis is having a deadly impact on the state. Among Black individuals in particular, overdose rates have increased by nearly a third. As such, we must examine ways to effectively intervene to reduce deaths among this underrepresented population.

METHOD

The current study utilized a thematic analysis to examine factors influencing treatment perceptions and experiences among a sample of 39 Black adults with a recent history of opioid use.

RESULTS

The primary themes highlighted in the study included "autonomous accessibility," "provider characteristics," and "relational support," which are aligned with Self-Determination Theory.

CONCLUSIONS

We discuss how these themes relate to treatment initiation, engagement, and completion and discuss implications of this research in treatment for Black adults. Specifically, we discuss treatment considerations among Black adults who use prescription opioids such as ensuring autonomy and a collaborative approach to treatment, especially in mandated treatment, with strategies such as motivational interviewing. Further, we discuss the importance of nonjudgmental providers, gauging client preferences for racially, ethnically, and gender matched providers; and we assess support networks among clients and how these networks can be integrated or utilized in treatment planning.

Improving Research on Racial Disparities in Access to Medications to Treat Opioid Use Disorders

OBJECTIVES

The aims of the study are to review the current research on the association between access to medications for opioid use disorders (MOUD) and race, to identify gaps in research methods, and to propose new approaches to end racialized disparities in access to MOUD.

METHODS

We conducted a literature review of English language peer-reviewed published literature from 2010 to 2021 to identify research studies examining the association between race and use of, or access to, MOUD.

RESULTS

We reviewed 21 studies related to access to MOUD for Black and White populations. Of the 21 studies, 16 found that Black individuals had lower use of, or access to, MOUD than White individuals, 2 found the opposite among patients in specialty addiction treatment, 1 found that the difference changed over time, and 2 found that distance to opioid treatment programs was shorter for Black residents than for White residents.

CONCLUSIONS

To improve future research, we recommend that researchers (1) be clearer on how race is conceptualized and interpreted; (2) explicitly evaluate the intersection of race and other factors that may influence access such as income, insurance status, and geography; (3) use measures of perceived racism, unconscious bias, and self-identified race; (4) collect narratives to better understand why race is associated with lower MOUD access and identify solutions; and (5) evaluate the effect of policies, programs, and clinical training on reducing racial disparities. A multitude of studies find that Black individuals have lower access to MOUD. Researchers must now identify effective solutions for reducing these disparities.

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

AIMS

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Engaging Disability Rights Law to Address the Distinct Harms at the Intersection of Race and Disability for People with Substance Use Disorder

This article examines the unique disadvantages experienced by Black people and other people of color with substance use disorder in health care, and argues that an intersectional approach to enforcing disability rights laws offer an opportunity to ameliorate some of the harms of oppression to this population.

Epigenetic and Genetic Factors Associated With Opioid Use Disorder: Are These Relevant to African American Populations

In the United States, the number of people suffering from opioid use disorder has skyrocketed in all populations. Nevertheless, observations of racial disparities amongst opioid overdose deaths have recently been described. Opioid use disorder is characterized by compulsive drug consumption followed by periods of withdrawal and recurrent relapses while patients are participating in treatment programs. Similar to other rewarding substances, exposure to opioid drugs is accompanied by epigenetic changes in the brain. In addition, genetic factors that are understudied in some racial groups may also impact the clinical manifestations of opioid use disorder. These studies are important because genetic factors and epigenetic alterations may also influence responses to pharmacological therapeutic approaches. Thus, this mini-review seeks to briefly summarize what is known about the genetic bases of opioid use disorder in African Americans.
