“Dr. Wennberg is an epidemiologist who noticed in the 1960s that enormous variation existed in the ways that physicians practiced medicine,” the Times notes. “For instance, in one Vermont town, about 70 percent of all children were having their tonsils removed by the time they reached adolescence. In another town nearby, only about 20 percent of children had the procedure.
“There were no differences in the children in these two places. Tonsillitis was not more common in one town, and the children were no more or less healthy before or after the procedure. The doctors just seemed to have very different attitudes toward how to take care of tonsils. And when Dr. Wennberg started presenting his data to the doctors in the first town, they changed their practice.”
