In my three-part series on why we know so little about ACOs, I presented three arguments:
- We have no useful information on what ACOs do for patients;
- that’s because the definition of “ACO” is not a definition but an expression of hope; and
- the ACO’s useless definition is due to dysfunctional habits of thought within the managed care movement that have spread throughout the health policy community.
Judging from the comments from THCB readers, there is no disagreement about points 1 and 3. With one exception (David Introcaso), no one took issue with point 2 either. Introcaso agreed with point 1 (we have no useful information on ACOs), but he argued that the ACO has been well defined by CMS regulations, and CMS, not the amorphous definition of “ACO,” is the reason researchers have failed to produce useful information on ACOs.
Another reply by Michael Millenson did not challenge any of the three points I made. Millenson’s point was that people outside the managed care movement use manipulative labels so what’s the problem?
I’ll reply first to Introcaso’s post, and then Millenson’s. I’ll close with a plea for more focus on specific solutions to specific problems and less tolerance for the unnecessarily abstract diagnoses and prescriptions (such as ACOs) celebrated today by far too many health policy analysts.
Summary of Introcaso’s comment and my response
I want to state at the outset I agree wholeheartedly with Introcaso’s statement that something is very wrong at CMS. I don’t agree with his rationale, but his characterization of CMS as an obfuscator is correct.


Donald Trump is leading the Republican delegate count and has the best chance of becoming the Republican nominee and, just maybe, even President. In February, we at THCB 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. Fittingly, that
Approximately 12 million Americans utilize some type of home health care every year. From home health aides visiting the infirmed in their homes, to physical therapy services to aide in recovery, to medical equipment being used to treat the chronically ill, home health has been a critical component of care management for decades.
Healthcare options are changing dramatically. Technological and market developments give people the power to take control of their own health and wellness, now more than ever before. Companies are constantly creating new consumer applications that seek to solve problems across the full spectrum of the healthcare lifecycle. These products include everything from contact lenses that measure blood glucose levels to an application that lets me chat with a psychiatrist at a moment’s notice. But despite recognizing the added convenience and personalization, I’m surprised by how frequently I ignore the sheer variety of products at my disposal in favor of doing things the old-fashioned way. Just this past week, I had to schedule my yearly checkup. Instead of booking my appointment through a service like ZocDoc or DocASAP, I instinctively grabbed my phone and tried to call a doctor. Why?
