According to Eisenberg (Medical Care 2002):
“Although physicians’ professional fees represent only one fifth of health care expenditures, they are responsible far decisions that govern the way that as much as 90% of each health care dollar is used.”
One way to change behavior is to give physician feedback. Here’s how to do it right:
“…the simple transmission of feedback to physicians may alter behavior, but when it is provided in an impersonal manner (such as form letters), it is often considered to be offensive and threatening. Feedback is most successful when offered face-to-face by a respected member of the medical professional community, when it is individualized for the physician, and when it represents current or at least recent data.”
