The Affordable Care Act is transforming more than health insurance. In hospitals around the country, the legislation could transform the way doctors and nurses actually care for patients. Part of the law is designed to rein in the nation's exploding health care costs by creating hundreds of little experiments that test new ways for hospitals to save money. One example: At Summa Akron City Hospital in Akron, Ohio, doctors are preparing for a new way of doing business. Michael Firstenberg, a heart surgeon at the hospital, says there's something a little funny about the way he gets paid.
