I came across this piece on the Healthcare Blog penned by Kip Sullivan, Esq, critiquing this article posted in Health Affairs last May ‘Bending The Spending Curve By Altering Care Delivery Patterns: The Role Of Care Management Within A Pioneer ACO‘. Sullivan raises valid points as the the legitimacy of claiming or inferring statistically insignificant results as a meaningful contribution of the subject ACO (a Partners Health sponsored venture) to ‘bending the cost curve’.
Sullivan un-bundles his argument effectively and raises issues for the industry writ large – including participating ACOs, their sponsors, the regulatory crew at both CMS and CMMI – and even the health policy press covering the sector.
- Is it ethical for health policy researchers to claim that a Medicare ACO reduced “spending” by 2 percent if the reduction was not statistically significant?
- Is it ethical for them to do so if they made no effort to measure the cost to the ACO of generating the alleged 2 percent savings nor the cost to Medicare of giving half the savings to the ACO?
- Does it matter that the researchers work for the flagship hospital within the ACO that was the subject of their study?
- Does it matter that the ACO and the flagship hospital are part of a huge hospital-clinic chain that claims its numerous acquisitions over the last quarter-century constitute not mere empire-building but rather “clinical integration” that will lower costs, and the paper lends credence to that argument?
- Is it ethical for editors to publish such a paper? Is it ethical to do so with a title on the cover that shouts, “How one ACO bent the cost curve”?
These questions were raised by the publication of a paper by John Hsu et al. about the Pioneer ACO run by Partners HealthCare System, a large Boston hospital-clinic chain, in the May 2017 edition of Health Affairs. Of the eight authors of the paper, all but two teach at Harvard Medical School and all but two are employed by Massachusetts General Hospital (MGH), Partners’ flagship hospital and Harvard’s largest teaching hospital. 
Partners has been on a buying and ….
As someone who’s been in this dance since the mid 70s (PSROs, HSAs, HMOs, IPAs, PPOs, EPOs & all derivative plays) launched into Medicare risk via TEFRA (the Tax Equity and Fiscal Accountability Act) which introduced us to ‘Medicare Choice’ the for-runner of Medicare Advantage, I can say Sullivan’s critique of fully ‘burdening‘ ALL transformational efforts is rarely – if ever – factored into the volume to value pivot ‘investment calculus‘ of the effects of the intervention (in this case a Pioneer ACO) on the national spend.
It should be noted, the entire managed care industry can be assessed a gigantic collective FAIL for that matter as well. Since managed care penetrated ‘mainstream medicine‘ principally via extension of the HMO model typically on an IPA (independent practice association) chassis (vs. group or staff models) with the exception of a brief period in the 90s premiums continue their relentless upward march; while most payors continue to write commercial business only via an enterprise and industry wide cost shifting (risk transfer) charade. The tacit admission that there is no there there in the prevailing health insurance industry zeitgeist. They’ve proven they can NOT manage clinical risk, period.
So Kip, you might want to go a little lighter on those on the front lines trying to tame the ‘rapacious appetite’ of our ‘healthcare borg‘!
