We all think we know what good medicine looks like: smart doctors, stethoscopes, imaging machines, high-tech tests, and the best prescriptions and procedures money can buy. But that picture is vastly incomplete. In this eye-opening book, physician Rishi Manchanda says that our health may depend even more on our social and environmental settings than it does on our most cutting-edge medical care. Manchanda argues that that the future of our health care depends on growing a new generation of health care practitioners. We need doctors who look upstream for the sources of our problems, rather than simply go for quick-hit symptomatic relief. These upstreamists, as he calls them, are doctors and nurses on the frontlines of medicine who see that health (like sickness) is more than a chemical equation that can be balanced with pills and procedures administered within clinic walls. They see that health begins in our everyday lives, in the places where we live, work, eat, and play. If our high-cost, sick-care system is to become a high-value, health care system, the upstreamists will show us the way.
