Causes of death in geriatric patients: a cross-cultural study.
BACKGROUND
The elderly are living longer and causes of death are shifting. At the same time, autopsy rate is at, or near, its lowest in history, compounded by an even lower interest in geriatric autopsies. Thus, the prevalent cause of death in this age group remains poorly studied.


METHODS
In a retrospective study, the autopsy protocols of 440 70-year-old or older patients from the Houston Veterans Affairs Hospital and 321 80-year-old or older patients from the II*Institute of Pathology in Prague (Czech Republic) were reviewed in order to establish a correct cause of death. The autopsy diagnosis was correlated with the prosectors' description of pathological findings in the protocol. In questionable cases or discrepancies, the patient's clinical chart and/or the histological autopsy slides were also reviewed.


RESULTS
The distribution of death by infections and cardiac disorders each accounted for one-third of all deaths. Congestive heart failure prevailed in the over 80-year-olds, and myocardial infarcts prevailed in the younger patients. The number of deaths due to malignancy dropped from 25% in those 70-79 years old to about 10% in the elder patients. Central nervous system disorders were frequent as an underlying disease, but were not common as a cause of death. The findings were similar in both series, thus supporting their accuracy.


CONCLUSIONS
Our findings bring into question the accuracy of reported causes of death in the elderly. With increasing age, differences appear in the levels of mortality and morbidity for various disease categories. This study underlines the need for more baseline data for older people which can be obtained only by more and well-performed autopsies.
