About 6.9 million Americans aged 65 and older live with Alzheimer's disease and related dementias (AD/ADRD). People living with dementia (PLWD) are hospitalized and visit emergency departments more often than they need to, and this gap is larger for low-income, rural, and racial and ethnic minority groups.

What they work on
- Identify people living with dementia who receive care from nurse practitioners serving as main or ancillary primary care providers, by correcting Medicare claims for incident-to billing and applying the Primary Care Provider Identification Algorithm (PCP-IA).
- Compare the sociodemographic and racial and ethnic composition of dementia patients across the two nurse practitioner primary care models, using 2023 Medicare data covering all beneficiaries.
- Determine how each nurse practitioner care model affects all-cause and preventable hospitalizations and emergency department visits among people living with dementia, using multilevel statistical models.
- Evaluate which nurse practitioner primary care model reduces racial and ethnic disparities in hospital and emergency department use among older adults with Alzheimer's disease and related dementias.
More about the research
Good primary care can help, but there are not enough physicians. Nurse practitioners (NPs), the fastest-growing part of the primary care workforce, emphasize care coordination and screening for social needs. This project asks how NP-led primary care affects outcomes and health disparities among older adults with dementia.
Why it matters
Older adults with dementia, especially those who are low-income, rural or from racial and ethnic minority groups, face high rates of avoidable hospital and emergency visits. Showing which nurse practitioner primary care models reduce these visits and narrow disparities could guide health systems and policymakers in using the growing NP workforce, and lay the groundwork for larger studies of NP care for people with dementia.
