As per recent study, conducted at Massachusetts General Hospital, Boston USA, the major diagnostic discrepancies / errors are up to 20-30% of cases, suggesting that the working or final clinical diagnosis may be wrong in as many as one in five patients overall.
Diagnostic errors are estimated to account for 40,000–80,000 deaths annually in U.S. hospitals alone. These figures only partially account for patients whose ambulatory misdiagnoses lead to death, and they do not include nonlethal disability, which may be just as common as death.
