On Tuesday, the newspapers discussed an article in Health Affiars that showed that while costs had declined, there is no evidnece that the ACA is a factor. While I agree that there is no defnitive evidence that the ACA is a factor, I think there is a very reasonable possibility that it is. The White House agrees that the ACA is a factor.

Some provisions that could make a difference: Pay for performance, Hospital readmission penalties, more emphasis on accountable care organizations, other integration initiatives (e.g. in post-acute care), 80% requirement on medical underwriting, and expansion of community health centers. In Medicare: more preventive services in Medicare and closing the donut hole. The creation of the exchanges is another factor as the insurance companies are likely to have lowered costs to be competitive in the marketplaces.
