Potentially Inappropriate Medication Use Among Patients With Dementia in Traditional Medicare and Medicare Advantage
Eli Raver, Jeah Kyoungrae Jung, Caroline Carlin, Roger D Feldman, Sheldon M. Retchin, Wendy Xu. Medical Care, 2025-05-19
Topic: Risk, prevention and care in population studies
MA-PD enrollees had significantly lower utilization of PIMs than standalone PDP enrollees: a 0.7 percentage-point [95% CI: 0.5, 0.8] lower prevalence of potentially harmful drug-disease interactions in older adults with dementia; a 3.1 percentage-point [2.6, 3.5] lower prevalence of potentially harmful drug-disease interactions in older adults with dementia and a history of falls; and a 0.5 percentage-point [0.4, 0.6] lower prevalence of high-risk medications in older adults. MA-PD enrollees with dementia experienced consistently lower prevalence of PIM use than those in PDP. As Medicare advantage enrollment continues to grow, it will be increasingly important to identify and leverage the features of MA-PD plans that promote safe medication prescribing for Medicare beneficiaries with dementia.

Key findings
- MA-PD enrollees had significantly lower utilization of PIMs than standalone PDP enrollees: a 0.7 percentage-point [95% CI: 0.5, 0.8] lower prevalence of potentially harmful drug-disease interactions in older adults with dementia; a 3.1 percentage-point [2.6, 3.5] lower prevalence of potentially harmful drug-disease interactions in older adults with dementia and a history of falls; and a 0.5 percentage-point [0.4, 0.6] lower prevalence of high-risk medications in older adults.
- MA-PD enrollees with dementia experienced consistently lower prevalence of PIM use than those in PDP.
- As Medicare advantage enrollment continues to grow, it will be increasingly important to identify and leverage the features of MA-PD plans that promote safe medication prescribing for Medicare beneficiaries with dementia.
Why it matters
This study compared use of potentially inappropriate medications between Medicare Advantage and standalone prescription drug plan enrollees with dementia. It found Medicare Advantage enrollees had lower use of these medications, which is about safer prescribing rather than treating, curing or preventing Alzheimer's disease.
