Doctor misdiagnoses are common

Many Americans will be diagnosed incorrectly at least once in their lifetimes. That is the troubling finding made in a newly issued report by the Institute of Medicine (IOM). The report found that diagnostic errors are by far the most pervasive in medicine, outranking medication mistakes.

An estimated 12 million patients are misdiagnosed in the United States each year. A major part of the problem is a lack of communication, according to the report.
