The autopsy and vital statistics.

Vital statistics in the United States are collected through a decentralized, cooperative system of various levels of government administrated by the National Center for Health Statistics. Although registration of all deaths is virtually complete and demographic items are accurate, the reliability of cause of death data is hampered by the current state of medical knowledge, the incompleteness of information available at the time of death, the way in which physicians complete death certificates, and the system of classification of underlying cause. The need for quality assurance in national cause of death statistics can be met in large part by connecting the autopsy to the mainstream of vital statistics. Through case by case individual linkage of death certificates and autopsies in designated demographic and/or geographic areas, a representative, continuously collected, population-based system of aggregated autopsy data would be created. Demographic and clinical selection bias should be checked and adjusted through traditional methods of epidemiologic standardization. Such a use of autopsy information could further pathology's goals of understanding disease and improving the public health.
