In the bucolic Upper Connecticut River Valley in New Hampshire an academic medical center is working to rewrite the book on healthcare with the help of predictive analytics, wearable devices and the cloud. "It's important to think about healthcare being on the precipice of what I think of as an industrial revolution," says Dr. Jim Weinstein, president and CEO of Dartmouth-Hitchcock Health System, a nonprofit academic health system that serves a patient population of 1.2 million people in New England. "The current system is not sustainable. It costs too much, is too diffuse and not efficient."
