Five billion medical claims will be analyzed by Health Care Cost Institute team to find a way out of unsustainable spiral of health care costs

For the first time, data from four of the largest U.S. health insurers, Aetna, Humana, Kaiser Permanente and UnitedHealth Group, plus government data from Medicare Fee For Service and Medicare Advantage will be analyzed (after being stripped of patient IDs) by a research team headed by Carnegie Mellon University professor Martin Gaynor.

The data includes information on more than 5,000 hospitals, a million health care providers and more than $1,000,000,000,000 in health care spending over the last decade.
