Autopsies improve the accuracy and significance of mortality statistics by providing precise, evidence-based documentation of the disease processes present at the time of death.1

Rather than relying on clinical estimates, which may be subject to error, the detailed examination of a body allows physicians to correlate clinical findings with anatomical reality. By confirming the specific causes and mechanisms of death, autopsies ensure that statistical data reflects the true nature of health outcomes within a population. Furthermore, these examinations often serve as the initial indicator of emerging contagions or epidemics, allowing for more reliable public health tracking and data collection.1
