The Federal Trade Commission recently held a day-long workshop focusing on Accountable Care Organizations. ACOs will vertically integrate hospitals and doctors and, in the process, achieve what previous incarnations of vertical integration could not. Let’s forget about whether ACOs will actually fulfill the dream of efficient healthcare delivery and focus on the FTC angle – will the creation of ACOs require the creation of provider market power and should he FTC therefore look the other way?
Many health economists have documented the perils of provider market power. Some of my own research has been instrumental in turning the tide against providers, whose monopolizing tendencies used to get a free pass from the courts. But as policy makers move ACOs to the fore, providers are hoping to sweep antitrust under the rug.
The latest salvo comes from the AHA, which last week released a study challenging two recent studies of hospital market power and then strains to connect their findings to ACOs. The AHA report goes a bit overboard in its criticism of these studies. One study consists of little more than anecdotes and should not be criticized for being anything else. The other study is more complex and the criticism is equally complex, mostly along the lines of “if you had measured things slightly differently, your results would have been slightly different.” The AHA report would have readers believe that these two studies represent the entire body of knowledge about hospital mergers. Having summarily dismissed them, the argument against FTC enforcement would seem complete.
