Diagnostic advances v the value of the autopsy. 1912-1980

Abstract

Between 1912 and 1980, many English language publications analyzed the correlation between clinicians' diagnoses and postmortem examinations. Surprisingly, the percentage of cases with undiagnosed principal underlying diseases or primary causes of death has not diminished during this period. The autopsy's unvarying percentage yield does not indicate a lack of progress, however, since bacterial pneumonia, hepatic cirrhosis, and common tumors were missed routinely in earlier eras but were rarely missed after 1970. Pulmonary embolism remains commonly missed, but the striking recent finding is the emergence of fungal and other systemic infections that were rarely noted in prior eras. Progress in diagnosis and treatment may allow patients to live longer and new or obscure diseases may develop that will often be missed clinically. An appropriately high autopsy rate will be required if medical progress is to continue.
