Disparities in Treatment for Alcohol Use Disorder Among All of Us Participants

The authors examined racial/ethnic and socioeconomic disparities in receiving treatment for alcohol use disorder (AUD).

A retrospective cohort study was conducted that included adults (≥18 years) with AUD from the All of Us Controlled Tier database v7. Outcomes were lifetime receipt of FDA-approved medications (disulfiram, acamprosate, and naltrexone), psychotherapy (individual, family, and group-based session), and combination treatment (medication and psychotherapy). The study examined treatment receipt by race/ethnicity (non-Hispanic White, non-Hispanic Black, Hispanic, other), insurance (private, Medicare, Medicare and Medicaid, Medicaid, Veteran Affairs [VA], none), income (<$10K, $10-<$50K, $50-$100K, >$100K), and area deprivation index (ADI) quintiles. Multivariable logistic and multinomial logistic regressions were used to assess the association between patient characteristics and treatment receipt.

The cohort consisted of 18,692 patients (mean age=57.1 years; 60.7% were male; 47.1% were non-Hispanic White). Almost 70% received no treatment, 11.4% received medication, 24.0% received psychotherapy, and 4.9% received combination treatment. In adjusted analysis, non-Hispanic Black (aOR=0.78, 95% CI=0.69-0.89) and Hispanic (aOR=0.75, 95% CI=0.64-0.88) individuals were less likely to receive medication than non-Hispanic White counterparts. There was no association between race/ethnicity and receipt of psychotherapy or combination treatment. Compared with private insurance, dual eligibility was associated with less use of medication, Medicare and Medicaid with less use of medication and combination treatment, and VA and no insurance with more use of psychotherapy and combination treatment. Higher income and lower ADI were positively associated with all treatment types.

There are disparities in AUD treatment by race/ethnicity, socioeconomic status, and insurance. Systematic approaches are required to improve equitable access to effective treatment.
