Services Provided in Spanish in Substance Use Disorder Treatment Facilities: Limited Access in Communities with...

Substance use disorder (SUD) is increasing among primary Spanish-speaking populations, and treatment use is disproportionately low. Patient-provider Spanish language concordance is associated with SUD treatment initiation and better outcomes. Recent geographic shifts within primary Spanish-speaking populations are important considerations in identifying gaps in SUD service delivery in Spanish. This national epidemiologic study used the Mental Health and Addiction Treatment Tracking Repository (2022; N = 9336 facilities) and US census data to pinpoint the location of SUD treatment facilities that offer services in Spanish, and used multilevel models to determine whether access to Spanish services is keeping up with the influx of primary Spanish-speaking populations in new areas that have not historically had a large Spanish language presence. Twenty-two percent of SUD treatment facilities provided services in Spanish. For every 10% increase in the percentage of a census tract speaking Spanish, the odds of SUD treatment facilities offering services in Spanish increased by 30% (aOR = 1.03, 95% CI = 1.02-1.04, p < 0.0001), indicating that Spanish language services were more common in places where people who speak Spanish already live. In contrast, the study team identified no association between the availability of Spanish services and increases in community-level Spanish between 2010 and 2022 (aOR = 1.00, 95% CI = 0.99-1.01, p = 0.87), indicating that access to services is not keeping up with demand as populations move and the Spanish language grows in new areas. SUD treatment services are lagging behind as the location of where primary Spanish-speaking families choose to live changes. Local health policies and ambitious interventions are needed that target the unique needs of SUD treatment clients who speak Spanish.
