Abstract
There have been two waves of equity-based investment in physician practices. Both used a combination of public and private sources but in different mixes. The first investment wave, in the 1990s, was led by public equity and physician practice management companies, with less involvement by private equity (PE). The second investment wave followed the Affordable Care Act and was led by PE firms. It has generated concerns of wasteful spending, less cost-effective care, and initiatives harmful to patient welfare. This article compares the two waves and asks if they are parallel in important ways. It describes the similarities in the players, driving forces, acquisition dynamics, spurs to consolidation, types of equity involved, models to organize physicians, and levels of market penetration achieved. The article then tackles three unresolved issues: Does PE investment differ from other investment vehicles in concerning ways? Does PE possess capabilities that other investment vehicles lack and confer competitive advantage? Does physician practice investment offer opportunities for supernormal profits? It then discusses ongoing trends that may disrupt PE and curtail its practice investment. It concludes that past may be prologue, that is, what happened during the 1990s may well repeat, suggesting the PE threat is overblown.
