Dr. Kevin Powell is concerned about the amount of money wasted in health care in the U.S. ($750 billion in 2009):
I recall a TV series where in each episode a patient arrives at the hospital emergency department and a brilliant young intern rattles off a litany of tests before examining the patient. It makes a good action script but bad medical care.
And he wonders about the risks and costs of CT scans for head injuries in children:
Given recently published data on the risks of radiation, is a head CT of a child who bumped his head really indicated “just to be on the safe side” or is it harmful defensive medicine?
