Edward Norton (Michigan) et al. find Medicare Shared Savings Program may not be working as well as thought

“As the Medicare system seeks to improve the care of older adults while also keeping costs from growing too fast, a new University of Michigan study suggests that one major effort may not be having as much of an impact as hoped.
A new analysis of data from the Medicare Shared Savings Program finds that high-cost physicians and high-cost patients dropping out of the program accounted for much of the savings reported from 2008 to 2014.”
