Autopsy in elderly psychiatric inpatients: a retrospective review of autopsy findings of deceased elderly psychiatric inpatients in north Cheshire 1980-1996.

In this 17-year review of death certificates of elderly inpatients of a large psychiatric hospital in North Cheshire, the frequency, trend and value of performing autopsies were examined. Details of death certificates were compared with certificates issued after post-mortem examination to see whether an autopsy yielded any additional or relevant information about conditions that are not directly related to death but might well be of importance to public health. The rate of post-mortem examination, at 9.5% of total hospital deaths, did not show any significant trend over most of the review period. The vast majority of autopsies examined had been requested by the coroner and not by the clinicians. The review showed that an autopsy may be of some value in providing more information regarding any underlying causes of death in elderly psychiatric patients, but has no value in ensuring higher rate of the recording of conditions such as dementia, in particular Alzheimer's disease. Selective hospital autopsy in elderly psychiatric patients to verify, neuropathologically, the clinical diagnosis of Alzheimer's disease, will improve our diagnostic accuracy and provide valid statistics to be used in estimating prevalence, trends, risk factors and for use in all aspects of future research into Alzheimer's disease.
