Private-equity firms accelerated their acquisitions of doctors' practices between 2013 and 2016, according to a new JAMA study.

Why it matters: "Private equity firms expect greater than 20% annual returns, and these financial incentives may conflict with the need for longer-term investments in practice stability, physician recruitment, quality, and safety," the author writes.

  • "There may be additional pressures to increase revenue streams (eg, elective procedures and ancillary services), direct more referrals internally, and rely on lower-cost clinicians," she adds.

By the numbers: 355 physician practices were acquired by private-equity firms over the time period, a small portion of total practices. But industry reports suggest that the growth kept up in 2017 and 2018.

  • The most commonly acquired medical groups were anesthesiology, multi-specialty practices and emergency medicine.

Between the lines: The role of private equity in health care has fallen under heavier scrutiny recently, as Congress examines the billing practices of physician groups that are frequently private equity-owned.

  • Private equity might have made things worse for itself when it became involved in the surprise billing debate via physician staffing firms that it backs.
  • These groups have poured millions of dollars into ads urging Congress not to pass a surprise billing solution that'd be more costly to providers.

The U.S. has already celebrated Easter, graduations and so much more during the coronavirus pandemic, and now it can add July 4 to the list.

The state of play: Axios' Stef Kight writes public parades and fireworks displays around much of the country are being canceled to prevent mass gatherings where the virus could spread. Hot-dog contests and concerts will play to empty stands and virtual audiences — all while American pride treads an all-time low.
