Our country urgently needs research on the impact of “accountable care organizations” on cost and quality. The ACO has been the establishment’s great hope for health care reform since the concept was invented at the November 9, 2006 meeting of the Medicare Payment Advisory Commission. If ACOs are not going to work, we need to know sooner rather than later.
Although it’s been almost a decade since the ACO concept was invented and six years since Congress endorsed it, we know remarkably little about ACOs. What little reliable research we have was done on CMS’s ACO programs, but even that research is woefully incomplete. As for the ACOs set up by state Medicaid agencies and insurance companies, we know almost nothing.
Yes, I know, we have a few dozen papers telling us where ACOs are starting up, whether physicians or hospitals are “leading” them, and whether their managers tells pollsters they can “monitor care across the continuum” and “have programs in place to reduce hospital admissions,” etc. But we have no idea what ACOs do for patients that non-ACO providers do not do.
There are two reasons for this information vacuum. The first is the definition of the ACO. ACO proponents have never defined the ACO; they have told us only what they hope ACOs will do (they tell us they want ACOs to “hold providers accountable”). The second problem is the cavalier attitude toward evidence with which ACO proponents and analysts approach ACO research. Until the US health policy community addresses these problems, the dearth of useful research on ACOs will continue.
In this comment, I will describe these twin problems – the amorphous, aspiration-based definition of ACO, and the casual attitude toward evidence exhibited by ACO proponents and analysts. In Part II of this series I will illustrate these problems with a report on ACOs financed by the Robert Wood Johnson Foundation.

Donald Trump is leading in the polls and could become the Republican nominee and maybe even President. He has not been specific on healthcare. I asked Scottish-Canadian-Californian healthcare futurist Ian Morrison to conduct an interview with Trump, figuring that Morrison would have an in with Trump given Trump’s praise for Scottish and Canadian healthcare. Not entirely coincidentally Ian is my old boss & mentor and will be a keynote speaker at
