Here's a visual display, courtesy of your DMCB, of the payouts for each of the five years to each of the participating clinics:
As you can see, four out of the ten, Billings ($0), Everett ($129,000, barely registering on the graph), Forsyth ($0), Middlesex ($0) didn't do very well for any of the years. Dartmouth hit a $6 million jackpot only in Year 2, Park Nicolette hit $5 million in Year 5, Geisinger had modestly successful Years 2 and 3. The only institutions with any consistency were Marshfield, St. Johns and Michigan.
1) assuming these results are generalizable, there is a 40% chance that an organization participating in a shared savings arrangement with CMS will come away practically empty handed, 30% of the participating organizations will have some good and and more bad years, there is 10% chance that an organization can get a huge amount of money and that this will work as intended only 20% of the time;
3) even if there is "savings," we don't know if the millions of those shared savings are greater than the millions in investments that each of the clinics had to make. That key information on "return on investment" remains conspicuously absent;
