title: The forensic pathology of nonagenarians and centenarians: do they die of old age? (The Auckland experience).
abstract: The aim of this study is to provide awareness of the common causes of death and their associated trends in the very aged. Forensic autopsies on patients aged >90 years were reviewed. The study lasted from January 1, 1988 to December 11, 1998 and was done in Auckland, New Zealand, the population of which is 1.3 million. Cases were divided into natural or unnatural deaths. Of the total of 319 cases, 272 (85%) deaths were natural. Of those, only 13 (5%) were "written off" as being attributed to old age or senile debility. The most common causes of death were ischemic heart disease (IHD), 74 cases (23%); bronchopneumonia, 37 cases (12%); fractures, 28 cases (9%); acute myocardial infarction, 25 cases (8%); cerebrovascular accident, 19 cases (6%); and ruptured aneurysm, 17 cases (5%); 61 (19%) deaths were multifactorial. Fractures, either as the primary cause of death or as a complicating factor, accounted for 29 cases, third only to IHD and bronchopneumonia. Forty-seven deaths (15%) were unnatural; of those, 43 were accidents, 3 were suicides, and 1 was a homicide. From these results it is clear that the very elderly succumb to disease; they do not often die of old age.
