New interactive tool tracks private equity investments in U.S. health care

New interactive tool maps the presence of private equity in the American medical sector, offering a detailed

Released officially on Tuesday, September 8, a new interactive digital instrument provides the general public, journalists, researchers, and policymakers with a granular analysis of private equity investments in United States health care. The project was conceived by researchers at the Center for Advancing Health Policy through Research at Brown University. Named the „Private Equity State Tracker,”this resource monitors the evolution of over 6,000 financial transactions carried out by private investors in health care. It covers all 50 states during the period spanning from 2015 to 2023. The included data reflects simple acquisitions alongside takeovers of independent physician-run clinics and entire hospitals.

Yashaswini Singh, an assistant professor of health services, policy, and practice at Brown University who significantly contributed to developing this tool, emphasizes that the platform addresses an essential need in the current landscape. Because private equity transactions are inherently confidential and lack strict regulatory oversight, they often remain invisible to the public. Consequently, researchers and decision-makers have had to rely on costly commercial databases and intensive manual research efforts to reconstruct where these capital flows concentrate.

Singh explained that the fundamental goal of the tracker is to shift the discussion away from ideological debates—which center on whether private equity is beneficial or harmful—toward an approach grounded in concrete evidence. The objective is to address the corporatization of the health care system as a complex and unified phenomenon. She warns that viewing private equity in isolation risks missing the bigger picture. There is a danger of regulating a single channel of corporatization while others expand unnoticed, occupying the space left behind.

Platform users can explore private equity transactions filtered by state, county, and zip code, observing how financial activity changes over time. Furthermore, they can analyze investments according to medical specialties, such as general practice, orthopedics, or oncology, to better understand the footprint of private investors in medical provider markets.

Aggregated data reveals interesting correlations. For example, the tracker indicates that in states where a higher number of doctors work directly for hospitals, private equity involvement tends to be lower. In contrast, in states where the proportion of hospital-employed physicians is smaller, the presence of investment funds is more pronounced. Yashaswini Singh gave the example of Indiana, where the majority of oncologists are employees of hospitals and integrated health systems. This structure reduces opportunities for private equity firms to buy individual practices from independent physicians.

The contrast is evident in Texas, where fewer than half of oncologists are affiliated with hospital institutions. In this context, private equity-backed entities have managed to employ approximately a third of independent physicians, demonstrating a more aggressive penetration of the local market.

Although the project was initially designed to help policymakers, the tool is free and open to all user categories, including researchers, journalists, and interested citizens. The underlying data drives the tracker and can be downloaded for further analysis. The Brown University team developed this project with financial support from the Commonwealth Fund and in close collaboration with the National Academy for State Health Policy. The researchers acknowledge that while the instrument is comprehensive, it may not capture every single private equity investment in U. S. health care. Still, it provides a solid starting point for identifying broader patterns and trends regarding where and how private equity firms invest.

Singh and her colleagues at the Center for Advancing Health Policy through Research believe that the increased transparency offered by this tool will help both decision-makers and the public better understand dynamics within their own states, especially when considering new policies regarding ownership and consolidation in the medical sector.

„In the current year, I have testified before six state legislatures debating policies designed to manage the corporatization of health care,”Singh shared. She noted a surprisingly consistent aspect across all these debates: both lawmakers and citizens were genuinely astonished by the sheer scale of private equity presence within their respective state health systems.
