The healthcare equation

By Robert Bazell, NBC News Chief science correspondent

Almost no one talks about health care reform without mentioning  the need to contain costs. Tonight we begin a two-part series about a collection of experiments run by Duke University that set out to rein in the price of medicine by actually improving care for patients with private insurance, those enrolled in the state's Medicaid program, and those with no insurance at all. You can get descriptions of the various programs here: http://communityhealth.mc.duke.edu/quicklinks.
