The Center for Diagnostic Excellence at Johns Hopkins University estimates that 12 million Americans have their health conditions misdiagnosed each year. Center researchers also note that errors in diagnosing patients’ cause harm to around 4 million people annually. Anywhere from 40,000 to 80,000 patients die in U.S. hospitals every year because the cause of their life-threatening health condition was either not correctly diagnosed at all or not diagnosed in a timely manner.
