Use a private equity (PE) health care tracker to find leads, not to settle ownership by itself. Check what the tracker counts and when its data apply, then trace the provider through its operating entity and parent companies and verify important links against public records. Brown University’s tracker is designed to show state-level investment trends from 2015–2023; the Private Equity Stakeholder Project’s July 2026 tracker is a list of hospitals it identifies as PE-owned. They answer different questions.
What can a health care PE tracker tell you?
A tracker can help you locate reported investments, compare activity across places or time, and identify providers for further investigation. It cannot automatically establish who owns a particular hospital or practice today. Some tools count historical transactions, some estimate clinician affiliations, and others present a snapshot of facilities classified as currently PE-owned.

Before using an entry, note the tracker’s sector, geography, date range, definition of PE involvement, unit counted, and update date. Also check how it treats exits, joint ventures, real estate, and system-level deals. A result is meaningful only within those boundaries.
Which tracker should you use?
| Resource | What it covers | Best suited to | Important scope limit |
|---|---|---|---|
| Brown University Private Equity State Tracker | Healthcare PE investment trends across all 50 US states from 2015–2023. Physician-practice investment data draw on PitchBook, Medicare Data on Provider Practice and Specialty (MD-PPAS), and manual review. Hospital acquisition data for 2015–2023 are based on the public dataset by Kim and colleagues. | Exploring historical, state-level investment trends and estimated provider affiliations. | Its hospital investment component excludes psychiatric, rehabilitation, and long-term acute-care settings; it is not a complete current ownership register. |
| Private Equity Stakeholder Project (PESP) Private Equity Hospital Tracker | A hospital ownership list described in a July 20, 2026 release. PESP estimated approximately 447 PE-owned US hospitals in that release. | Finding hospitals PESP classifies as PE-owned in its July 2026 snapshot. | PESP describes the list as approximate. Its count and classifications belong to that release and can change. |
Use Brown for trends, not a current-owner verdict
Brown links investment information to 2023 MD-PPAS data to estimate physician affiliations and uses the AHRQ Compendium of US Health Systems for hospital affiliations. An affiliation result indicates a link in the tracker’s data; it should not be read as a complete legal ownership history.
#1 Best Overall
Brown notes that healthcare PE transactions are not subject to systematic reporting or disclosure requirements, so smaller unreported transactions may be absent. Medicare data omit some specialties and non-physician providers. The tracker also excludes certain staffing-firm arrangements and lacks systematic information on exits and deal structures such as management-services organizations (MSOs), leveraged buyouts, and joint ventures. Those limitations affect what an affiliation or trend result can establish.
Use PESP as a dated hospital list
PESP’s definition includes traditional buyouts and growth or expansion capital, as well as hospitals operated through more complex arrangements such as joint ventures with nonprofit or academic health systems. The July 2026 tracker added fields for joint ventures and REIT ownership of hospital real estate. In that release, PESP estimated that 21.4% of its PE-owned hospitals were held through joint ventures with nonprofit systems, and that at least 136 of the 447 listed hospitals—30.4%—had real estate owned by REITs. These are PESP’s estimates for its stated release, not permanent counts.
Rank #2
PESP says it identified hospitals using news searches and PitchBook and also consulted CMS Hospital All Owners Information. It found CMS ownership data useful for clues but generally insufficient on their own to trace PE ownership. Its facility-counting rules have changed over time; for example, the project describes consolidating multiple CMS identifiers at one location when the same owner applies.
How do you investigate a provider from a tracker entry?
- Capture the entry and its context. Record the provider or facility name as shown, state, tracker name, update or release date, classification, and any cited transaction or owner. Save the relevant notes about inclusion rules and facility counting.
- Identify the care site and operating entity. Match the public-facing hospital or practice to its legal operating entity. Names can differ, so look for identifiers and legal names in state business filings, CMS records, or other public records relevant to the provider.
- Trace the parent chain backward. Follow the operating entity to its parent, platform company, management company, holding companies, and fund vehicles where records allow. A sponsor name in a tracker may be one link in the chain rather than the direct legal owner of the care site.
- Check primary public records. Relevant records can include SEC Form ADV, SEC Form D, state business filings, and federal or state court records. Review what each document actually establishes: a filing may identify an adviser, fund, entity, or relationship without proving every link in a facility’s ownership chain.
- Use announcements and reports as corroboration. M&A announcements and public pension reports may help establish timing or a fund relationship. A public-record ownership methodology cautions against relying on those sources alone to establish ownership.
- Reconcile identities and dates. Check whether a transaction refers to a whole health system, a subsidiary, or individual facilities; compare facility identifiers and acquisition or exit dates. If the legal chain or match is not established by cited records, label the result unverified rather than calling the provider independent or PE-owned.
Why do tracker counts and deal histories differ?
Healthcare transactions are not systematically disclosed, and data providers may record the same activity at different levels. One database might describe a system acquisition, another list each hospital, and another omit a facility or categorize the transaction differently. Duplicate deals and inconsistent facility identifiers can therefore alter both totals and conclusions.
Rank #3
A 2026 study by Kim and colleagues combined six commercial databases—Irving Levin Associates, PitchBook, Preqin, Capital IQ, FactSet, and SDC Platinum—and reconciled duplicates, matched targets to AHA and CMS identifiers, manually reviewed uncertain matches, and checked deal and exit dates. For short-term acute-care hospitals over 2000–2024, the study identified 141 unique PE deals involving 555 unique hospitals, or 721 hospital-deal observations. These are results from that study’s constructed dataset, not an estimate of all health care PE activity or a count directly comparable to PESP’s July 2026 ownership snapshot.
How should you compare two trackers?
- Population: Does it cover acute-care hospitals, other hospital types, physician practices, clinicians, or a specific specialty?
- Investment definition: Does PE mean buyouts only, or does it include growth capital, joint ventures, or other financial relationships?
- Time basis: Is the result a transaction history or a current ownership snapshot? Are exited or sold entities still shown as affiliated?
- Unit of analysis: Is the tracker counting deals, systems, facilities, practices, clinicians, or ownership links?
- Matching method: How does it handle system-level acquisitions, duplicates, facility identifiers, and manual review?
- Evidence and refresh date: Which filings, commercial databases, CMS records, announcements, or archived websites support entries, and when was the list last updated?
- Uncertainty: Does the publisher explain omissions, corrections, or changes to classification and counting rules?
Do not add a current-ownership count to a historical deal count or clinician-affiliation estimate and present the sum as one measure. Their populations, dates, and units may be different.
Rank #4
How should you report what you found?
For a statement about a specific hospital or practice, cite the underlying filing or ownership record when available. Use the tracker as evidence of its own compilation, method, date, or estimate—not as a substitute for the underlying record. If a tracker is the only evidence you can find, attribute the classification to that tracker and give its release date.
Keep the qualification attached to any figure. For example, say that PESP’s July 20, 2026 release estimated approximately 447 PE-owned US hospitals; do not turn that into a timeless count. Brown asks users who download its data to cite the tracker. Where no public record establishes the ownership chain, say that ownership remains unverified based on the records you found.
