What this research studies
If you've had a stroke, researchers will use Medicare and linked health records to follow what happens to people over 1, 5, and 10 years. They will combine Medicare fee-for-service and Medicare Advantage data from 2017–2024 with an existing patient-linked surveillance database to track repeat strokes and other outcomes. The team will examine patterns by age, race, geography, and other factors to find disparities in who gets recurrent strokes and long-term disability. This is an observational analysis of existing records rather than a treatment trial, so no extra clinic visits or new medications are involved.
Who could benefit from this research
Good fit: Older adults (typically 65 and up) who have had an ischemic stroke and are captured in Medicare records are the main group this work applies to.
Not a fit: People under 65, those without Medicare coverage, or individuals whose strokes are not recorded in the linked databases are unlikely to be included or directly benefit.
Why it matters
Potential benefit: If successful, the findings could help clinicians and health systems identify older patients at high risk for repeat strokes and design better follow-up and prevention programs.
How similar studies have performed: Past studies have documented disparities in recurrent stroke, but combining fee-for-service and Medicare Advantage records for long-term 1-, 5-, and 10-year outcomes is a more comprehensive and relatively new approach.
