Private Equity Hospital Buyouts Linked to Higher ER Deaths, Staffing Cuts

Using national Medicare claims with cost reports, researchers tie post‑buyout staffing reductions to higher transfers and deaths.

Overview

  • A peer‑reviewed study in Annals of Internal Medicine finds emergency department mortality rose 13.4% after acquisitions compared with matched non‑acquired hospitals.
  • The increase equates to about seven additional deaths per 10,000 emergency visits from a baseline of 52 per 10,000.
  • Salary expenditures fell by 18.2% in emergency departments and 15.9% in intensive care units, with reductions in average full‑time staff at acquired hospitals as controls increased staffing.
  • Patient transfers to other acute care hospitals rose 4.2% from baseline in emergency departments and 10.2% in intensive care units, while ICU length of stay declined by 4.7%.
  • Researchers used difference‑in‑differences analyses of RAND‑collated cost reports (2007–2019) and 100% Medicare Fee‑for‑Service claims (2009–2019) for hospitals acquired between 2010 and 2017, with funding from NIH and AHRQ.
