Who could benefit from this research

Could help

Ideal candidates are Medicare beneficiaries with chronic diseases who receive primary care from practices that have been acquired by private equity firms or from similar non-PE practices for comparison.

Less likely to help

Patients treated at PE-acquired practices without measurable changes in utilization or quality within the study period may see no direct benefit.

What this research studies

Researchers will link data from private equity ownership of primary care practices with Medicare claim and encounter data from 2016–2024 to compare patients treated before and after PE acquisitions. Using a quasi-experimental event-study design, they will look at changes in utilization, quality, and costs among beneficiaries seen at PE-acquired practices versus similar non-PE practices. The focus is on Traditional Medicare and Medicare Advantage populations, with attention to chronic disease management and potential overuse or wasteful services. Results could reveal how ownership structures influence care delivery for millions of Medicare beneficiaries.

Why it matters

Potential benefit: If successful, the study could inform policy and provider strategies to safeguard high-quality, cost-effective care for Medicare patients with chronic diseases.

How similar studies have gone: Previous studies in other settings show higher prices and spending with PE ownership, but effects on primary care and Medicare outcomes are not yet clear.
