What this research studies

Researchers will use national Medicare data to compare access, quality, and use of care between Medicare Advantage (MA) plans and Traditional Medicare (TM). They will examine whether these differences vary for people with different incomes, races, and other demographic characteristics. The team will identify MA plans that consistently deliver better outcomes for different types of beneficiaries. They will also create and test patient-reported questionnaires to measure how consistent and reliable care feels to enrollees.

Who could benefit from this research

Good fit: Medicare beneficiaries—especially older adults enrolled in Medicare Advantage or Traditional Medicare and those from diverse income and demographic groups—would be the focus for surveys or data analyses.

Not a fit: People who are not enrolled in Medicare (for example, younger adults with only private insurance) are unlikely to be affected directly by this project.

Why it matters

Potential benefit: If successful, this work could help people on Medicare choose plans that provide better access and quality and inform policy changes to improve care across Medicare.

How similar studies have performed: Prior research has compared MA and TM with mixed results, and developing validated patient-reported measures for plan performance is a more recent effort.
