Tracking Medicine

John Wennberg is a medical doctor and researcher who has spent much of the last half century analyzing the practice of medicine across the United States.

He has used Medicare patients’ treatment records to show that health delivery is often more dependent on the supply of providers and facilities in an area than the expected demand for such treatment of the area population.

He and his associates have also shown that more intensive treatment generally does not result in better care and sometimes leads to more adverse outcomes.
