In this issue of JAMA Internal Medicine, La Forgia et al1 describe the prices paid for anesthesia services before and after health care facilities (hospital outpatient departments and ambulatory surgical centers) either contracted with or were owned by a physician management company (PMC), half of which had received private equity funding. Private equity firms typically invest in businesses for 3 to 7 years with the expectation of 20% to 30% returns.2 Not surprisingly, at facilities involved with PMCs, allowed charges increased by an average of 16.5%. The subset of facilities involved with private equity–backed PMCs saw allowed charges increase by 26.0%.1
