Racial And Ethnic Disparities In Buprenorphine Receipt Among Medicare Beneficiaries, 2015-19.

We examined Medicare Part D claims from the period 2015-19 to identify state and national racial and ethnic disparities in buprenorphine receipt among Medicare disability beneficiaries with diagnosed opioid use disorder or opioid overdose. Racial and ethnic disparities in buprenorphine use remained persistently high during the study period, especially for Black beneficiaries, suggesting the need for targeted interventions and policies.

Typology of laws restricting access to methadone treatment in the United States: A latent class analysis.

BACKGROUND: In the United States, methadone treatment for opioid use disorder is only available at opioid treatment programs (OTPs). In addition to federal regulations, states can enact laws which shape access to OTPs. We aimed to define classes of states according to restrictiveness of state OTP laws and examine population characteristics associated with class membership. METHODS: A set of laws was extracted from a database of statutes and regulations governing OTPs in 49 states and the District of Columbia as of June 2021. Latent class analysis of laws was used to estimate the probability of class membership for each state. Class-weighted multinomial logistic regression analysis assessed state-level correlates of class membership and adjusted Relative Risk Ratio (aRRR) and 95% confidence intervals (95%CI) were generated. RESULTS: States (n = 50) were assigned to three classes; Class 1) High restrictiveness on patient experience, low restrictiveness on access to service (n = 13); Class 2) Medium restrictiveness on patient experience, high restrictiveness on access to service (n = 14); Class 3) Low restrictiveness on patient experience, low restrictiveness on access to service (n = 23). States with a higher probability of membership in Classes with higher restrictiveness had higher rates of unemployment (Class 1 vs Class 3, aRRR:1.24; 95%CI:1.06-1.45), and Black residents (Class 2 vs Class 3, aRRR:1.10; 95%CI:1.04-1.15), and lower likelihood of Medicaid coverage of methadone (Class 1 vs Class 3, aRRR:0.25; 95%CI:0.07-0.88). States with a higher probability of membership in Classes with higher restrictiveness also had higher rates of potential indicators for opioid use disorder treatment need, including rates of opioid dispensing (Class 1 vs Class 3, aRRR:1.06; 95%CI:1.02-1.10, Class 2 vs Class 3, aRRR:1.07; 95%CI:1.03-1.11) and HIV diagnoses attributed to injection (Class 1 vs Class 3, aRRR:3.92; 95%CI:1.25-12.22). CONCLUSIONS: States with indicators of greater potential need for opioid use disorder treatment have the most restrictions, raising concerns about unmet treatment need.

Substance Use, Service Provision, Access & Utilization among Foreign-Born Communities in the United States: A Mixed Methods Study.

BACKGROUND: The prevalence of substance use among the foreign-born has gained increasing attention. Cumulative migration stressors - including historical trauma, violence, family separation, and poverty - present challenges to human service systems wherein services may not adequately meet the needs of these groups. Objectives: This study explores the challenges and realities of substance use, substance use service provision, and delivery of services among the increasingly diverse immigrant population using multiple perspectives. This study is based on data from a larger mixed methods study that assessed the human service landscape pertaining to the immigrant population in a mid-western region of the United States. Methods: This transformative mixed methods study used a community based participatory research approach. Data were collected from human service providers (HSPs), informal service providers, and local community leaders through surveys (n = 64), in-depth interviews (n = 23), and six focus group discussions (n = 48). A weaving approach was used to integrate findings from quantitative and qualitative data. Results: Participants recognize substance use as an issue that needs immediate attention among increasingly diverse immigrant communities. Community members and human service organizations identified several emergent themes including patterns and occurrence of substance use, barriers to care, and proposed system changes. Conclusions: Given that only 28% of responding organizations list substance use as part of their core services, the need for organizational collaborations with a focus on culturally responsive evidence-based services is proposed.
