Death certificates are important because morbidity and mortality stati
stics often come from death-certification data. These statistics are v
ital in developing approaches to disease treatment and strategies for
increasing longevity. It is often the primary care physician who is re
sponsible for completing the death certificate, for explaining the cau
se of death to the family and, if appropriate, for referring some case
s to the medical examiner. The primary care physician should have an e
xplicit understanding of how to determine the cause and manner of deat
h and should use succinct, clear language in completing the death cert
ificate, When doubt exists or an external cause of death is a possibil
ity, the coroner or the medical examiner is the appropriate public hea
lth official to contact.
