Medicaid-covered alcohol and drug treatment use among people with intellectual disabilities: evidence of disparities.

Slayter (2010) looked at Medicaid records. The goal was to see how many people with intellectual disabilities get drug or alcohol treatment.

The study compared people with ID to other Medicaid clients. It used billing codes to spot who entered substance-use care.

People with ID were far less likely to start treatment. The gap was large even when they had the same insurance.

In plain words, having ID acted like an extra wall between clients and help.

van Duijvenbode et al. (2015) later showed why the wall exists. Their review found almost no ID-friendly screening tools or programs.

Luteijn et al. (2020) added that zero studies test combined PTSD and addiction care for this group. Together these papers say the gap is still wide.

Hall et al. (2007) used the same Medicaid trick. They saw low primary-care use by adults with ID, echoing the access theme.

Bassett-Gunter et al. (2017) gave a bright spot. Simple questionnaires plus staff reports catch drug use as well as lab tests. So we can spot the need even if services are missing.

If you serve adults with ID, expect extra steps to place them in substance-use care. Start early, loop in caregivers, and track authorizations. Push payers for plain-language programs and flexible funding. Your advocacy can turn insurance on paper into real treatment in the chair.
