The misdiagnosis crisis

This story starts off with a little boy in Georgia who, unlike me, actually managed to see a doctor on a Saturday. It didn’t help:

The doctors on weekend duty ordered blood tests, which showed that the boy had leukemia. There were a few things about his condition that didn’t add up, like the light brown spots on the skin, but the doctors still scheduled a strong course of chemotherapy to start on Monday afternoon. Time, after all, was their enemy. [...]

What the doctors didn’t know was that the boy had a rare form of the disease that chemotherapy does not cure. It makes the symptoms go away for a month or so, but then they return. Worst of all, each round of chemotherapy would bring a serious risk of death, since he was already so weak.

With all the tools available to modern medicine - the blood tests and M.R.I.’s and endoscopes - you might think that misdiagnosis has become a rare thing. But you would be wrong. Studies of autopsies have shown that doctors seriously misdiagnose fatal illnesses about 20 percent of the time. So millions of patients are being treated for the wrong disease.

As shocking as that is, the more astonishing fact may be that the rate has not really changed since the 1930’s. ”No improvement!” was how an article in the normally exclamation-free Journal of the American Medical Association summarized the situation.
