Who could benefit from this research

Could help

Ideal candidates include researchers and clinicians studying aging, ADRD, and health disparities who need rich CMS data to examine real-world care patterns.

Less likely to help

Patients who do not participate in any direct data collection will not be affected; this grant does not involve enrolling individuals in a trial.

What this research studies

This grant supports a data core that collects and enhances Medicare and Medicaid records, making them accessible to researchers. It will add Medicare Advantage and Medicaid data and improve measures of ADRD symptoms, dementia stages, and cognitive impairment. The project also aims to identify race, ethnicity, and caregiver links to better understand health disparities in older adults. Researchers will collaborate with other cores to implement advanced algorithms and ADRD measurements within the CMS data infrastructure. The work focuses on enabling high-quality studies that could inform better care for older patients with dementia and related conditions.

Why it matters

Potential benefit: If successful, this data resource could clarify how dementia care varies across populations and support studies that improve diagnosis, treatment patterns, and equity for older adults.

How similar studies have gone: Previous data cores have shown that linked claims data can yield valuable insights into dementia care and disparities when augmented with advanced measurements.
