The trend toward investor ownership is part of a broader national shift in health-care consolidation, said Hayden Rooke-Ley, a senior fellow at Brown University’s School of Public Health. Over the last decade, large non-hospital retailers such as Amazon and Walgreens, along with insurance conglomerates, have restructured to own or manage medical practices, drug distributors and wholesalers.

On October 6, 2025, California Governor Gavin Newsom signed SB 351, aimed at limiting the involvement of private equity groups and hedge funds in health care practices.

In the first half of 2025, states enacted numerous laws to strengthen their health care markets. These new laws address several recurring policy issues affecting states across the country, including skyrocketing health care costs, increased consolidation in the healthcare sector, and the heightened penetration of private equity in health care systems.

A bipartisan group of lawmakers has introduced legislation to stop Medicare Advantage insurers from collecting billions in federal payments for veterans who primarily receive care through the VA. Sparked by a Wall Street Journal investigation—supported by data from Brown University researchers—the bill aims to close a loophole that enabled an estimated $44 billion in excess payments from 2018 to 2021.

Several states are adopting hospital price caps to curb rising healthcare costs, citing limited success from other reforms. Supporters see savings, while hospitals warn of revenue loss and service cuts. See what CAHPR's Roslyn Murray, Ph.D. has to say.

On Wednesday, the state House passed Senate Bill 951, the latest effort to expand Oregon’s prohibitions on corporate ownership in local care providers.

This news video features Dr. Andrew Ryan, Director of CAHPR, discussing his study on Rhode Island’s hospital affordability standards, which led to significant hospital price and premium reductions—saving $1,000 per fully insured member by 2022.

This article reports on a study by CAHPR researchers that found that Rhode Island’s 2010 hospital price growth cap significantly reduced hospital prices and lowered premiums for fully insured health plans by $1,000 per member annually by 2022. However, the policy had limited impact on the self-insured market due to federal ERISA regulations, and the resulting hospital revenue losses have raised concerns about financial sustainability and care quality.

A Nevada bill aims to cap hospital fees for the Public Employees’ Benefits Program to reduce costs, drawing on Oregon's model, which researcher Roslyn Murray of Brown University studied and found led to significant savings without shifting costs to private insurers.

This news article highlights the study led by Dr. Roslyn Murray on potential savings achieved by capping state employee health plans while discussing how rising health care costs are squeezing state dollars.

This article talks about the analysis conducted by CAHPR researchers who find that routine medical care costs four times more in New York’s outpatient hospital facilities than in doctor’s offices, largely due to added facility fees. Economist Christopher Whaley and other experts have long highlighted such pricing disparities, fueling legislative efforts like the proposed Fair Pricing Act to cap these costs.

Gloria Sachdev has spent years challenging high hospital prices in Indiana, successfully pushing for healthcare cost transparency and legislative reforms. Her efforts, have led to a national report on hospital pricing and significant policy changes in the state.

This article covers a Brown University study, published in Health Affairs, which found that the Colorado Option lowered average marketplace premiums by $101 per month since 2020, while exchange premiums nationally rose by 10%.

This article talks about two conflicting studies on the Colorado Option emerged—one, funded by the insurance industry, found only 2% of plans met the 10% premium reduction goal, while another, by Brown University researchers and backed by the Commonwealth Fund, highlighted it as a model, estimating $100 lower premiums than similar states without a public option.

This article covers criticisms from Colorado’s Health Care Future, which argues that the program has failed to lower premiums, harmed competition, and reduced consumer choices, while the state cites a Brown University analysis showing it provides affordable coverage and limits premium increases driven by rising hospital and provider costs.

Jared Perkins, Director of Health Policy Strategy at CAHPR discusses bridging the gap between academia and policymakers, the challenges of navigating health policy under a shifting political climate, and the importance of aligning research with legislative priorities.

The article discusses the proposed merger of Oregon Health & Science University (OHSU) and Legacy Health, which has drawn significant criticism for potentially violating federal antitrust standards. Advocates argue the merger would lead to excessive market consolidation in Oregon, controlling a majority of hospitals in key regions and potentially driving up healthcare costs without improving access or quality.

This news article covers the study led by CAHPR researchers who found that state employee health plans could save over $7 billion annually by capping hospital payments at 200% of Medicare rates. The findings suggest that such caps could ease budgetary pressures while minimizing disruptions to hospital operations.

This news article offers continued coverage on the impact of hospital payment caps and the potential for nationwide savings, based on the Health Affairs study led CAHPR researchers at the Brown University School of Public Health.

This news article provides continued coverage of the study by CAHPR researchers on hospital payment caps, and it's potential for saving billions without harming hospital finances.

The article examines California’s failed attempt to regulate private equity investments in healthcare through AB 3129, which proposed stricter transaction oversight and protections against corporate control of medical practices. It critiques the bill’s limited scope, exemptions, and political challenges while positioning it as a case study for future state-level reforms in addressing healthcare consolidation.

The article written by CAHPR researchers, emphasizes the opportunity for Congress, in its final weeks of the 118th session, to advance healthcare affordability and transparency through the Lower Costs, More Transparency Act (LCMT) and the Health Care PRICE Transparency Act 2.0

This article outlines six key points about Oregon's regulatory review of the OHSU-Legacy merger. Hayden Rooke-Ley's critique of the OHSU-Legacy merger, emphasizing how OHSU's broad market definition may obscure significant anticompetitive risks, presenting a critical test for Oregon's Health Care Market Oversight program.

This article examines the Oregon Health Authority's comprehensive review of the proposed merger between OHSU and Legacy Health, highlighting key concerns about market concentration, potential cost increases, and the future of health care access and competition in the region.

This article explores the study done by Brown researchers on the imapct of Oregon's hospital payment cap and how other US states have an opportunity to implement similar control measures to achieve health savings.

This issue brief provides key lessons for other states interested in hospital payment caps. These include setting caps above Medicare rates but below typical state plan prices to maintain provider participation, exempting small and rural hospitals to protect vulnerable facilities, and legislating payment caps to ensure long-term stability. Oregon’s approach offers valuable insights for states seeking to control health care spending while ensuring access to care.

State Treasurer Folwell's recent report with insights from Christopher Whaley unveils startling findings: North Carolina's 340B hospitals have been overcharging the state, shedding light on critical financial discrepancies in healthcare funding.

This article discusses Oregon's successful experiment in implementing price caps on hospital services, saving $107.5 million in two years, suggesting a viable solution for states battling soaring healthcare costs.
