Receipt Of Medications For Opioid Use Disorder Research Articles

Negative affect-associated drug refusal self-efficacy, illicit opioid use, and medication use following short-term inpatient opioid withdrawal management

IntroductionPersons with opioid use disorder (OUD) are prone to frequent relapse following brief inpatient medically managed withdrawal. This longitudinal, naturalistic study examines associations among illicit opioid use, use of medication for opioid use disorder (MOUD), and one's confidence in the ability to resist drug use in the face of negative emotions (i.e., negative affect–associated drug refusal self-efficacy). MethodParticipants were 220 adults with OUD who recently completed a short-term inpatient program and the study followed for 6 months. At baseline, participants reported demographics, illicit opioid use, recent engagement with MOUD, and negative affect–associated drug refusal self-efficacy. At follow-up (1 week and 1-, 3-, and 6-months following discharge), participants reported illicit opioid use and MOUD. ResultsParticipants averaged 30.7 years of age, 63.2% were male, and 84.1% were white. Both illicit opioid use and rates of MOUD increased during the 6-month follow-up period, although only 34.1% received MOUD. At baseline, participants reported less than 50% self-confidence to resist using opioids during negative emotional states. Baseline negative affect–associated drug refusal self-efficacy inversely predicted illicit opioid use (p = .01) at follow-up but was not associated with follow-up MOUD. ConclusionAmong persons with OUD, lower confidence to resist using opioids in negative emotional states predicts greater use of illicit opioids in the months following medically managed withdrawal, even with receipt of MOUD.

1007. Criminal Justice Involvement Negatively Impacts Engagement in Treatments for HIV and Opioid Use Disorder in Vietnam

BackgroundPeople living with HIV (PLWH) and opioid use disorder (OUD) commonly experience criminal justice involvement (CJI). We sought to estimate the impact of CJI on 1) HIV care engagement, 2) antiretroviral therapy (ART) prescription rates, and 3) receipt of medications for opioid use disorder (MOUD), among PLWH and OUD in Vietnam.MethodsParticipants were PLWH enrolled in a 12-month MOUD treatment trial of HIV clinic-based buprenorphine vs. methadone referral in Vietnam. We compared those with CJI (arrest, incarceration, or compulsory “06” drug rehabilitation) during the first 9 months of the study to those with no CJI. To ensure participants with CJI had the opportunity to re-engage in treatment, only those who were released before their 9-month study visit were included; participants still incarcerated at 9 months were excluded. Logistic regression models estimated the association between CJI and HIV care engagement (≥ 1 visit), ART prescription, and receipt of MOUD between 9 and 12 months, controlling for demographics, substance use, past CJI, and HIV history.ResultsAt baseline, 234 of 281 participants (83.6%) had a history of arrest/incarceration, and 172 (61.2%) reported prior 06 detention. During their first 9 months of study participation, 14 participants (5.0%) were arrested and 14 participants (5.0%) were sent to compulsory 06 rehabilitation. Being arrested (OR=0.04, 95% CI= (0.007, 0.25)), sent to compulsory 06 rehabilitation (OR=0.08, 95% CI= (0.02, 0.38)), or either (OR=0.07, 95% CI= (0.02, 0.24)), were negatively associated with receipt of MOUD. CJI involvement was also negatively associated with HIV clinic engagement after release (OR=0.20, 95% CI= (0.05, 0.84)). A similar negative association was noted for ART prescription, though it did not reach statistical significance (OR=0.17, 95% CI= (0.03, 1.22)).ConclusionArrest, incarceration, and compulsory 06 rehabilitation negatively impact HIV and OUD care among people with HIV and OUD in Vietnam. Policies that decrease incarceration, and the impacts of incarceration, for people with OUD and HIV may improve care outcomes in Vietnam and elsewhere.Disclosures P Todd Korthuis, MD, MPH, Alkermes & Indivior (Other Financial or Material Support, Dr. Korthuis serves at principal investigator for NIH-funded studies that accept donated study medicine from Indivior (buprenorphine) and Alkermes (extended-release naltrexone).)

Treatment for opioid use disorder in the Florida medicaid population: Using a cascade of care model to evaluate quality

ABSTRACT Background: A cascade of care (CoC) model may improve understanding of gaps in addiction treatment availability and quality over current single measure methods. Despite increased funding, opioid overdose rates remain high. Therefore, it is critical to understand where the health-care system is failing to provide appropriate care for people with opioid use disorder (OUD) diagnoses, and to assess disparities in receipt of medication for OUD (MOUD). Objective: Using a CoC framework, assess treatment quality and outcomes for OUD in the Florida Medicaid population in 2017/2018 by demographics and primary vs. secondary diagnosis. Methods: Data from Florida Medicaid claims for 2017 and 2018 were used to calculate the number of enrollees who were diagnosed, began MOUD, were retained on medication for a minimum of 180 days, and who died. Results: Only 28% of those diagnosed with OUD began treatment with an FDA approved MOUD (buprenorphine, methadone, or injectable naltrexone). Once on medication, 38% of newly diagnosed enrollees were retained in treatment for180 days. Those who remained on MOUD for 180 days had a hazard ratio of death of 0.226 (95% CI = 0.174 to 0.294) compared to those that did not initiate MOUD, a reduction in mortality from 10% without MOUD to 2% with MOUD. Conclusions: Initiating medication after OUD diagnosis offers the greatest opportunity for intervention toreduce overdose deaths, though efforts to increase retention are also warranted. Analyzing claims data with CoC identifies system functioning for specific populations, and suggests policies and clinical pathways to target for improvement.

Racial and Ethnic Disparities in Maternal and Infant Outcomes Among Opioid-Exposed Mother-Infant Dyads in Massachusetts (2017-2019).

Objectives. To examine the extent to which differences in medication for opioid use disorder (MOUD) in pregnancy and infant neonatal opioid withdrawal syndrome (NOWS) outcomes are associated with maternal race/ethnicity.Methods. We performed a secondary analysis of a statewide quality improvement database of opioid-exposed deliveries from January 2017 to April 2019 from 24 hospitals in Massachusetts. We used multivariable mixed-effects logistic regression to model the association between maternal race/ethnicity (non-Hispanic White, non-Hispanic Black, or Hispanic) and prenatal receipt of MOUD, NOWS severity, early intervention referral, and biological parental custody at discharge.Results. Among 1710 deliveries to women with opioid use disorder, 89.3% (n = 1527) were non-Hispanic White. In adjusted models, non-Hispanic Black women (AOR = 0.34; 95% confidence interval [CI] = 0.18, 0.66) and Hispanic women (AOR = 0.43; 95% CI = 0.27, 0.68) were less likely to receive MOUD during pregnancy compared with non-Hispanic White women. We found no statistically significant associations between maternal race/ethnicity and infant outcomes.Conclusions. We identified significant racial/ethnic differences in MOUD prenatal receipt that persisted in adjusted models. Research should focus on the perspectives and treatment experiences of non-Hispanic Black and Hispanic women to ensure equitable care for all mother-infant dyads.

Association of Treatment With Medications for Opioid Use Disorder With Mortality After Hospitalization for Injection Drug Use–Associated Infective Endocarditis

Although hospitalizations for injection drug use-associated infective endocarditis (IDU-IE) have increased during the opioid crisis, utilization of and mortality associated with receipt of medication for opioid use disorder (MOUD) after discharge from the hospital among patients with IDU-IE are unknown. To assess the proportion of patients receiving MOUD after hospitalization for IDU-IE and the association of MOUD receipt with mortality. This retrospective cohort study used a population registry with person-level medical claims, prescription monitoring program, mortality, and substance use treatment data from Massachusetts between January 1, 2011, and December 31, 2015; IDU-IE-related discharges between July 1, 2011, and June, 30, 2015, were analyzed. All Massachusetts residents aged 18 to 64 years with a first hospitalization for IDU-IE were included; IDU-IE was defined as any hospitalization with a diagnosis of endocarditis and at least 1 claim in the prior 6 months for OUD, drug use, or hepatitis C and with 2-month survival after hospital discharge. Data were analyzed from November 11, 2018, to June 23, 2020. Receipt of MOUD, defined as any treatment with methadone, buprenorphine, or naltrexone, within 3 months after hospital discharge excluding discharge month for IDU-IE. The main outcome was all-cause mortality. The proportion of patients who received MOUD in the 3 months after hospital discharge was calculated. Multivariable Cox proportional hazard regression models were used to examine the association of MOUD receipt with mortality, adjusting for sex, age, medical and psychiatric comorbidities, and homelessness. In the secondary analysis, receipt of MOUD was considered as a monthly time-varying exposure. Of 679 individuals with IDU-IE, 413 (60.8%) were male, the mean (SD) age was 39.2 (12.1) years, 298 (43.9%) were aged 18 to 34 years, 419 (72.3) had mental illness, and 209 (30.8) experienced homelessness. A total of 134 individuals (19.7%) received MOUD in the 3 months before hospitalization and 165 (24.3%) in the 3 months after hospital discharge. Of those who received MOUD after discharge, 112 (67.9%) received buprenorphine. The crude mortality rate was 9.2 deaths per 100 person-years. MOUD receipt within 3 months after discharge was not associated with reduced mortality (adjusted hazard ratio, 1.29; 95% CI, 0.61-2.72); however, MOUD receipt was associated with reduced mortality in the month that MOUD was received (adjusted hazard ratio, 0.30; 95% CI, 0.10-0.89). In this cohort study, receipt of MOUD was associated with reduced mortality after hospitalization for injection drug use-associated endocarditis only in the month it was received. Efforts to improve MOUD initiation and retention after IDU-IE hospitalization may be beneficial.

Associations Between Polysubstance Use Patterns and Receipt of Medications for Opioid Use Disorder Among Adults in Treatment for Opioid Use Disorder.

Objective:To examine trends in polysubstance use among adults in treatment for opioid use disorder (OUD) and estimate associations between polysubstance use patterns and receipt of medications for OUD (MOUD).Methods:We conducted a cross-sectional longitudinal analysis of treatment admissions for opioid use from 1992 to 2017 using the Treatment Episodes Data Set-Admissions (N = 9,440,157). We used multiple logistic regression to examine co-use patterns and estimate associations between receipt of MOUD and polysubstance use categories (opioid only, any methamphetamine, any cocaine, any alcohol, any benzodiazepine).Results:Between 1992 and 2017, treatment admissions involving opioid/cocaine (−17.2 percentage points [PP]) and opioid/alcohol co-use (−12.5 PP) decreased while opioid/methamphetamine (10.1 PP) and opioid/benzodiazepine co-use (5.6 PP) increased. In 2016 to 2017, receipt of medications for OUD was significantly higher for those who used opioids only (38.5%; 95% confidence interval [CI] 38.4–38.6) compared with individuals who used opioids with cocaine (35.7%; 95% CI 35.6–35.9), methamphetamine (23.9%; 95% CI 23.7–24.2), alcohol (25.0%; 95% CI 24.8–25.2), or benzodiazepines (34.6%; 95% CI 34.3–34.9). If those who co-used opioids with other substances received MOUD at the same rate as those who used opioids only, 47,400 additional people would have received MOUD between 2016 and 2017.Conclusions:Opioid/methamphetamine and opioid/benzodiazepine increased substantially between 1992 and 2017. Co-use of other substances with opioids was associated with significantly lower receipt of MOUD. Treatment facilities should increase access to MOUD for individuals who co-use opioids with other substances. This change would extend evidence-based treatment to thousands of individuals and save lives.

Medications for Opioid use Disorder Associated With Less Against Medical Advice Discharge Among Persons Who Inject Drugs Hospitalized With an Invasive Infection.

To identify the incidence, characteristics, and factors associated with against medical advice (AMA) discharge among hospitalized patients with opioid use disorder (OUD) and injection related infections (eg, endocarditis, osteomyelitis, epidural abscesses). This retrospective cohort study evaluated adults with OUD admitted to an academic medical center from January 1, 2016 to January 7, 2019 for an invasive injection related infection. Multivariable logistic regression was used to determine independent factors associated with AMA discharge. Among 262 adults admitted with serious injection related infections and comorbid OUD, 138 received inpatient medications for opioid use disorder (MOUD). Univariate analysis showed a decreased odds ratio (OR) of AMA discharge when patients received MOUD inpatient (OR 0.55; 95% CI 0.34-0.91.). Adjusting for covariates associated with social determinants of health and other substance use, inpatient receipt of MOUD was associated with a decreased risk of AMA discharge (adjusted OR 0.49; 95% CI 0.028-0.84). Among patients with OUD and serious injection related infections, inpatient initiation of MOUD is associated with decreased risk of AMA discharge.

Medications for opioid use disorder among pregnant women referred by criminal justice agencies before and after Medicaid expansion: A retrospective study of admissions to treatment centers in the United States.

Criminal justice involvement is common among pregnant women with opioid use disorder (OUD). Medications for OUD improve pregnancy-related outcomes, but trends in treatment data among justice-involved pregnant women are limited. We sought to examine trends in medications for OUD among pregnant women referred to treatment by criminal justice agencies and other sources before and after the Affordable Care Act's Medicaid expansion. We conducted a serial, cross-sectional analysis using 1992-2017 data from pregnant women admitted to treatment facilities for OUD using a national survey of substance use treatment facilities in the United States (N = 131,838). We used multiple logistic regression and difference-in-differences methods to assess trends in medications for OUD by referral source. Women in the sample were predominantly aged 18-29 (63.3%), white non-Hispanic, high school graduates, and not employed. Over the study period, 26.3% (95% CI 25.7-27.0) of pregnant women referred by criminal justice agencies received medications for OUD, which was significantly less than those with individual referrals (adjusted rate ratio [ARR] 0.45, 95% CI 0.43-0.46; P < 0.001) or those referred from other sources (ARR 0.51, 95% CI 0.50-0.53; P < 0.001). Among pregnant women referred by criminal justice agencies, receipt of medications for OUD increased significantly more in states that expanded Medicaid (n = 32) compared with nonexpansion states (n = 18) (adjusted difference-in-differences: 12.0 percentage points, 95% CI 1.0-23.0; P = 0.03). Limitations of this study include encounters that are at treatment centers only and that do not encompass buprenorphine prescribed in ambulatory care settings, prisons, or jails. Pregnant women with OUD referred by criminal justice agencies received evidence-based treatment at lower rates than women referred through other sources. Improving access to medications for OUD for pregnant women referred by criminal justice agencies could provide public health benefits to mothers, infants, and communities. Medicaid expansion is a potential mechanism for expanding access to evidence-based treatment for pregnant women in the US.

Outcomes Associated With Medications for Opioid Use Disorder Among Persons Hospitalized for Infective Endocarditis.

Endocarditis, once predominately found in older adults, is increasingly common among younger persons who inject drugs. Untreated opioid use disorder (OUD) complicates endocarditis management. We aimed to determine if rates of overdose and rehospitalization differ between persons with OUD with endocarditis who are initiated on medications for OUD (MOUDs) within 30 days of hospital discharge and those who are not. We performed a retrospective cohort study using a large commercial health insurance claims database of persons ≥18 years between July 1, 2010, and June 30, 2016. Primary outcomes included opioid-related overdoses and 1-year all-cause rehospitalization. We calculated incidence rates for the primary outcomes and developed Cox hazards models to predict time from discharge to each primary outcome as a function of receipt of MOUDs. The cohort included 768 individuals (mean age 39 years, 51% male). Only 5.7% of people received MOUDs in the 30 days following hospitalization. The opioid-related overdose rate among those who did receive MOUDs in the 30 days following hospitalization was lower than among those who did not (5.8 per 100 person-years [95% confidence interval [CI], 5.1-6.4] vs 7.3 per 100-person years [95% CI, 7.1-7.5], respectively). The rate of 1-year rehospitalization among those who received MOUDs was also lower than those who did not (162.0 per 100 person-years [95% CI, 157.4-166.6] vs 255.4 per 100 person-years [95% CI, 254.0-256.8], respectively). In the Cox hazards models, the receipt of MOUDs was not associated with either of the outcomes. MOUD receipt following endocarditis may improve important health-related outcomes in commercially insured persons with OUD.
