How the ACO REACH program might change care for people with Alzheimer's and related dementias

The Impact of the ACO REACH Program on Health Outcomes for Patients with Alzheimer's Disease and Related Dementias

NIH-funded research Washington University · NIH-11308703

This project compares a new Medicare payment model called ACO REACH with other Medicare arrangements to see whether people with Alzheimer's disease and related dementias get better care and health outcomes.

What this research studies

The researchers will use national Medicare data to compare beneficiaries in REACH ACOs, beneficiaries in the older MSSP ACOs, and beneficiaries not in any ACO. They will track outcomes important to people with dementia such as hospital visits, use of home-based services, and overall health service use. The team will also look at which specific care redesigns (for example, home-care waivers or global payments) ACOs implement and whether those changes help dementia patients. Washington University investigators will apply implementation science methods to link what ACOs do to what happens to patients.

Who could benefit from this research

Good fit: Ideal candidates are Medicare beneficiaries living with Alzheimer's disease or related dementias who receive care within Medicare programs, particularly those attributed to an Accountable Care Organization.

Not a fit: People who are not on Medicare (for example, younger individuals with early-onset dementia or those covered only by private insurance) or who receive care entirely outside ACO arrangements may not see direct benefits from this work.

Why it matters

Potential benefit: If successful, the findings could guide Medicare and health systems to adopt payment and care changes that reduce hospitalizations and increase home-based support for people with Alzheimer's and related dementias.

How similar studies have performed: Prior research on earlier ACO models has produced mixed results for older adults, and the REACH program is new, so its effects on dementia patients are largely untested.
