The Private Equity
Healthcare Machine

The private equity model in healthcare follows a predictable sequence: acquire a healthcare system using leveraged debt — meaning the target itself is responsible for repaying the acquisition loan. Cut staffing and operating costs to generate cash flow for debt service. Extract management fees, dividend recapitalizations, and sale-leaseback arrangements that strip assets from the operating entity. Then exit — selling to another PE firm, a strategic acquirer, or the public — before the compounding liabilities become someone else's visible problem.

This model is structurally incompatible with high-quality healthcare. Patient safety requires adequate staffing, long-term capital investment, and clinical decision-making insulated from quarterly extraction pressure. PE ownership delivers the opposite: debt obligations that demand cash extraction, staffing ratios designed for margin rather than safety, and a finite ownership horizon that penalizes long-term investment.

The peer-reviewed medical literature has now documented this pattern with clinical precision. A December 2023 study in JAMA — by Sneha Kannan, Joseph Dov Bruch, and Zirui Song — examined patient outcomes at hospitals before and after PE acquisition, comparing them to non-PE hospitals over the same period. The findings were unambiguous: PE acquisition causes measurable patient harm.

The JAMA 2023 study is the landmark peer-reviewed assessment of PE's clinical impact. The findings: hospitals acquired by PE firms saw a 25% relative increase in hospital-acquired adverse events compared to non-PE hospitals, controlling for hospital characteristics and market conditions. Broken down by type:

• +27%Increase in patient falls. Falls cause fractures, head injuries, and prolonged hospital stays. They are primarily a staffing-ratio outcome — fewer nurses means fewer eyes on at-risk patients.
• +38%Increase in central-line-associated bloodstream infections (CLABSIs). These are largely preventable with adherence to evidence-based protocols and adequate staffing. They carry a mortality rate of roughly 10–25%.
• +100%Increase in surgical site infections — a doubling. Surgical site infections extend stays, require additional procedures, and kill patients. They are strongly associated with staffing levels and sterile technique compliance.

The study also found that PE hospitals performed 8% fewer surgical procedures after acquisition — consistent with the model of cutting lower-margin services while extracting from higher-margin ones. Fewer procedures, worse outcomes on the ones that did occur.

This is not correlation. The study used difference-in-differences methodology comparing outcomes at PE-acquired hospitals before and after acquisition to matched non-PE hospitals over the same period — the standard design for isolating a causal effect. The authors' conclusion: PE acquisition of hospitals "was associated with increased adverse events and worse patient outcomes."

Hospitals are visible. Nursing homes are not. PE's penetration of the nursing home sector predates its hospital push by a decade — and the death toll has been accumulating longer.

A 2021 study published in the NBER — examining 18,000 nursing homes over 17 years — found a 10% higher mortality rate at PE-owned facilities compared to non-PE nursing homes. The researchers estimated this translated to 20,150 additional deaths attributable to PE ownership over the study period.

The mechanism was documented: PE acquisition was followed by a 1.4% reduction in total staffing and a 3% drop in direct care staff hours — nursing, hygiene, infection management, monitoring. Simultaneously, residents at PE facilities were 11.1% more likely to have a preventable emergency department visit and 11.1% more likely to be preventably hospitalized.

Preventable hospitalizations from nursing homes are a standard indicator of inadequate baseline care. The numbers indicate that PE-owned nursing homes were providing less care per resident — generating the margin to service acquisition debt — and that residents were paying for it with their health and lives.

Steward Health Care was the largest private for-profit hospital operator in the United States. It was also a private equity vehicle — Cerberus Capital Management acquired it in 2010 and executed a sale-leaseback of Steward's hospital buildings to Medical Properties Trust, a real estate investment trust. The deal stripped Steward of its own physical assets, leaving it paying rent on the hospitals it ran.

By 2024, Steward owed $9 billion in total liabilities, of which $6.6 billion were long-term rent obligations — the legacy of that sale-leaseback. On May 6, 2024, Steward filed Chapter 11 bankruptcy. It operated 33 hospitals in 8 states with approximately 33,000 employees.

The consequences were immediate and human: five hospitals permanently closed, including Carney Hospital in Dorchester, Massachusetts — a community hospital serving one of Boston's lowest-income neighborhoods — and Nashoba Valley Medical Center. Approximately 2,400 workers were laid off. Patients who had been receiving ongoing care were abruptly discharged or transferred.

The hospitals that didn't close were sold, mostly to nonprofit health systems — the public sector absorbing the wreckage of private extraction. The PE firms had already exited. The communities stayed. This is not an anomaly. Steward is the template made visible: a private equity firm buys a hospital system, extracts value through debt, fees, and sale-leasebacks, and leaves the community holding the liability when the model collapses.

Envision Healthcare was the largest physician staffing group in the United States — employing emergency medicine physicians, anesthesiologists, and neonatologists embedded in hospitals across the country. KKR acquired Envision in 2018 for $10 billion, loading the acquisition cost onto Envision's balance sheet.

Envision was KKR's vehicle for the surprise billing business: PE-owned physician staffing groups systematically placed out-of-network doctors in in-network hospitals, then billed patients at rates insurance companies wouldn't cover — generating the margin to service acquisition debt. Congress passed the No Surprises Act in 2020, effective 2022, largely as a response to this practice. The No Surprises Act eliminated the model.

Envision filed Chapter 11 bankruptcy on May 15, 2023, with approximately $7.7 billion in debt. The company eliminated more than $7 billion in debt through the bankruptcy process. KKR no longer owns Envision. The company that KKR leveraged into insolvency continues to operate under new ownership, smaller and stripped of its debt — but also of the investment KKR extracted during the five years it held it.

The pattern is consistent with Steward: acquisition via leveraged buyout, extraction during the holding period, bankruptcy when the model collapses, exit before the wreckage is visible. KKR's investors received their returns before Envision filed. The doctors, the patients, and the hospitals that had relied on Envision's staffing were left sorting out the aftermath.
