Key Takeaways
- • Brown University's Center for Advancing Health Policy through Research launched an interactive Private Equity State Tracker on September 8, 2026, mapping over 6,000 private equity investments in U.S. health care across all 50 states from 2015 to 2023.
- • The tool enables granular analysis by state, county, ZIP code, and physician specialty (primary care, orthopedics, oncology, etc.), addressing a critical information gap caused by lack of regulatory disclosure requirements for private equity transactions.
- • Data reveals inverse relationship between private equity activity and hospital employment of physicians: states with higher physician employment by hospitals show lower private equity involvement, and vice versa.
- • The tracker shifts focus from ideological debate toward evidence-based policymaking on health care corporatization by providing researchers, policymakers, journalists, and the public with transparent access to previously opaque deal data.
Summary
Brown University researchers have launched a comprehensive interactive mapping tool designed to illuminate private equity's expanding footprint in U.S. health care. The Private Equity State Tracker, developed by the university's Center for Advancing Health Policy through Research and released September 8, 2026, catalogs more than 6,000 private equity acquisitions and investments spanning the full 15-year period from 2015 to 2023 across all 50 states, encompassing physician practice acquisitions and hospital transactions.
The tool addresses a structural information asymmetry that has long hindered evidence-based policy discussions. Private equity deals remain largely undisclosed due to their private nature and the absence of comprehensive regulatory oversight, forcing researchers and policymakers to rely on fragmented commercial databases and labor-intensive manual analysis. Yashaswini Singh, an assistant professor of health services, policy and practice at Brown and a developer of the tracker, emphasized that the initiative aims to pivot conversations away from ideological positioning and toward data-driven analysis of health care consolidation more broadly. "If you only look at private equity in isolation, you miss that bigger picture, and you risk regulating one channel of corporatization while the other expands to fill the gap," Singh noted.
The platform's granular design allows users to filter transactions by geographic level (state, county, ZIP code) and medical specialty, revealing patterns across physician markets. Early data demonstrates a notable inverse correlation: states where larger proportions of physicians are employed directly by hospitals exhibit lower private equity acquisition activity, while states with lower hospital-employed physician rates show elevated private equity involvement. This pattern suggests private equity may serve as an alternative consolidation mechanism where hospital integration lags.
