Anti-Hypertensive Medication Use and Factors Related to Adherence Among Adults With Intellectual and Developmental Disabilities.

Chezan et al. (2019) looked at Medicaid records for adults with intellectual or developmental disabilities who also have high blood pressure. They wanted to know how many of these adults take their blood pressure medicine as prescribed and what helps them stick with it.

Only about half of the adults filled enough prescriptions to count as adherent. People living in supervised homes, those with a Medicaid waiver, and anyone who saw their primary care doctor often were more likely to keep taking the pills.

Ono (1998) seems to tell the opposite story: Japanese adults with ID who lived in group homes and took antipsychotics showed more behavior problems, not less. The difference is the drug class—C et al. tracked blood-pressure pills while Y tracked antipsychotics—so the setting helps with one med type but may signal extra needs with another.

Heald et al. (2020) adds that psychotropic use in Australian adults with ID keeps rising, driven by challenging behavior. Together the papers show that where someone lives matters, but the reason for the prescription matters too.

Yamaki et al. (2018) found that shifting these adults to Medicaid Managed Care did not save money, so the extra doctor visits that boost adherence in C et al. are still worth paying for.

If you serve adults with IDD, pair every new blood-pressure script with a plan for supervised dosing and regular primary-care follow-ups. Flag anyone who lives alone or rarely sees a doctor—these are the clients most likely to skip doses and land in the ER later.
