A growing share of US healthcare delivery

Private equity acquisitions in US healthcare have grown rapidly over the past two decades. The deal volume has accelerated sharply since 2010. PE now owns or controls a meaningful share of:

• US emergency room staffing (through firms like the now-bankrupt Envision and TeamHealth)
• Anesthesia, radiology, and other hospital-based specialty groups
• Roughly 8% of US nursing homes (and a much larger share of regional chains)
• A growing share of physician practices in dermatology, ophthalmology, gastroenterology, urology, and oncology
• Significant portions of dialysis clinics, dental chains, autism services, and behavioral health
• A small but rising number of full hospital systems

The total estimated PE-owned share of US healthcare delivery is debated; conservative estimates put it at 5-10%, while higher estimates include indirect ownership through portfolio companies and reach 15%+.

Why PE finds healthcare attractive

Healthcare has several features that match the private-equity business model unusually well:

• Stable cash flow. Healthcare demand is not very cyclical. Acute care, in particular, is something patients consume regardless of economic conditions.
• Heavily reimbursed by third parties. Most healthcare bills are paid by insurers or government programs, not patients directly. This makes price discrimination and aggressive billing less visible to the end consumer than in retail markets.
• Fragmented physician markets. Most US physician groups are small. Acquiring and rolling them up into larger entities can produce immediate scale economies and negotiating leverage with insurers.
• Real-estate value separate from operations. Hospitals, nursing homes, and clinics often own valuable real estate. Sale-leaseback transactions can extract that real-estate value while leaving the operations encumbered with rent obligations.
• Surprise billing and out-of-network leverage. Until the 2020 No Surprises Act, hospital-based specialty groups (ER physicians, anesthesiologists) could charge high out-of-network rates because patients had no realistic ability to choose them. PE-owned staffing firms exploited this aggressively.

What the empirical record shows

The clinical and financial consequences of PE ownership in healthcare have now been studied across many sub-sectors. The findings are remarkably consistent:

• Nursing homes: Studies of PE-acquired nursing homes show measurable increases in mortality (one large study estimated a 10% increase) and decreases in nurse staffing.
• Hospitals: Studies of PE-acquired hospitals show increases in adverse events, increases in costs to Medicare, and worse outcomes on standard measures.
• ER staffing: PE-owned ER staffing firms were central to the surprise-billing crisis pre-2020, and to subsequent EMTALA-compliance issues.
• Dialysis: Quality measures vary by chain, but several PE-acquired chains have faced significant federal enforcement actions.
• Physician practices: Acquired practices typically see prices rise (insurers pay more per visit) without corresponding quality improvements; pressure on physicians to see more patients per hour increases.

The picture is not uniformly negative — some PE acquirers have invested meaningfully in modernization and have improved operations. But the pattern is consistent enough that it cannot be dismissed as outliers.

The financial architecture

The PE business model in healthcare relies on a few standard moves:

1. Leveraged buyout. Acquire the target with substantial debt, much of it loaded onto the target’s balance sheet.
2. Real-estate sale-leaseback. Sell the underlying real estate to a REIT or affiliated entity, lease it back at high rates. Pulls cash out immediately; encumbers operations with permanent rent obligations.
3. Dividend recapitalization. Issue additional debt at the target to fund a dividend back to the PE owner. Pulls more cash out; encumbers operations further.
4. Cost cuts. Reduce staffing, shift labor mix toward lower-cost categories, reduce equipment and maintenance spending.
5. Volume expansion. Add lucrative service lines, increase patient throughput, optimize billing.
6. Exit. Sell to another PE firm (a “secondary buyout”) or to a strategic buyer in 5-7 years.

Each of these moves, separately, has been used in non-healthcare industries for decades. The combination, when applied to healthcare delivery, has consequences that the broader business literature did not anticipate — because the consumers of healthcare (patients) cannot price-shop, walk away, or substitute as freely as consumers in most markets.

The regulatory options

The reform agenda for PE in healthcare has been crystallizing over the past several years:

Disclosure. The most basic reform is requiring disclosure of PE ownership of healthcare entities. Currently, ownership is often opaque — a nursing home’s actual owner may be obscured behind multiple layers of LLCs and trusts. A few states have begun requiring disclosure; federal proposals would extend this to Medicare-participating providers.

Notice and review of acquisitions. Several state AG offices have begun reviewing PE acquisitions of hospitals and nursing homes. California’s SB 977 (proposed) would require state AG approval of healthcare-system acquisitions above a size threshold. Similar bills are pending in other states.

Restrictions on real-estate sale-leasebacks. Some proposals would limit a healthcare facility’s ability to sell its real estate and lease it back from an affiliated entity at above-market rates.

Mandatory minimum staffing ratios with enforcement teeth. Federal nursing-home staffing rules (finalized in 2024) are an example, though they face industry pushback and litigation.

Joint and several liability for PE owners. The Stop Wall Street Looting Act (federal) would make PE firms jointly and severally liable for portfolio-company debts in bankruptcy, removing the bankruptcy-as-exit option.

Cooling-off periods. Restrictions on PE-acquired hospital sales within a defined period after acquisition.

What to watch

• Federal nursing-home staffing rule implementation and litigation. Outcome will shape the most basic care-quality regulation.
• State-level acquisition-review legislation. Several states are advancing meaningful frameworks; outcomes vary.
• PE-owned ER staffing chain bankruptcies. Envision’s 2023 bankruptcy created precedent that other restructurings will follow; the resolution patterns are worth watching.
• CMS reimbursement reform. Site-neutral payment reform would reduce the incentive for hospital-system roll-ups.
• Federal disclosure proposals. Any rule requiring disclosure of beneficial ownership of healthcare entities would shift the information asymmetry materially.

Bottom line

Private equity in healthcare is not a fringe phenomenon. It is a meaningful and growing share of how Americans receive care, and the empirical record on its effects is sufficient to justify substantial regulatory response. The reforms above are not anti-investment; they are aimed at the specific financial and clinical patterns that produce predictable harms. The status quo — opaque ownership, aggressive financial extraction, weak accountability for clinical outcomes — is not a market failure that will self-correct. It is a regulatory failure that the public has the tools to fix.
