The summary of a study by National Bureau of Economic Research: The past two decades have seen a rapid increase in Private Equity (PE) investment in healthcare, a sector in which intensive government subsidy and market frictions could lead high-powered for-profit incentives to be misaligned with the social goal of affordable, quality care. This paper studies [PDF] the effects of PE ownership on patient welfare at nursing homes. With administrative patient-level data, we use a within-facility differences-in-differences design to address non-random targeting of facilities. We use an instrumental variables strategy to control for the selection of patients into nursing homes.

Our estimates show that PE ownership increases the short-term mortality of Medicare patients by 10%, implying 20,150 lives lost due to PE ownership over our twelve-year sample period. This is accompanied by declines in other measures of patient well-being, such as lower mobility, while taxpayer spending per patient episode increases by 11%. We observe operational changes that help to explain these effects, including declines in nursing staff and compliance with standards. Finally, we document a systematic shift in operating costs post-acquisition toward non-patient care items such as monitoring fees, interest, and lease payments.
