What about diagnostic errors?

In this posting, Robert Wachter, MD, who writes the blog Wachter's World, questions why there's so much buzz out there about medical errors while diagnostic errors go on everyday with little notice. He says that someday we may reach a point when all pneumonia patients receive antibiotics and heart patients are given aspirin in a timely manner, but if the doctors giving those orders are wrong in their diagnosis, we really won't have made any advances in patient safety.
