An autopsy, the medical examination of a deceased person, may confirm
clinical findings, provide more complete information to describe cause of
death, or uncover conditions not recognized clinically prior to death (1). Two
types are performed in the United States: a) hospital or clinical autopsies,
which family or physicians request to clarify cause of death or assess care,
and b) medicolegal autopsies, which legal officials order to further investigate
the circumstances surrounding a death (2). The autopsy rate, or percentage
of deaths that received this final assessment, was stable from the 1950s until
the beginning of the 1970s, when the autopsy rate began to decrease (3). This
report uses mortality data from the National Vital Statistics System (NVSS)
over a 35-year period to examine changes in the autopsy rate and in the
distribution of those autopsied by age and cause. Variation in autopsy patterns
has implications for which deaths may have a more complete and conclusive
cause-of-death determination.
