Introduction: Post-mortem examinations may result in considerable distress to the bereaved family. This audit was undertaken to examine whether computerised tomography (CT) scanning prior to death might reduce the need for post-mortems without compromising the accuracy of recording the cause of death.
Subjects and methods: The case notes of 100 consecutive patients who had a coroner's post-mortem, because the cause of death was unknown, were reviewed by four senior clinicians. Along with the likely cause of death, the clinicians gave their opinion as to whether a CT scan would have enabled certification of death without the need for a post-mortem. Concordance between the post-mortem findings and the clinical events surrounding death was explored.
Results: It would have been possible to perform a pre-mortem CT scan on 90 of the 100 patients. A pre-mortem CT scan would have given the cause of death in 59 (66%) of these. In 30 patients, the cause of death established by the post-mortem was at variance with the clinical events surrounding death and clinically relevant information, such as recent surgery, was not recorded on the death certificates of 26 patients.
Conclusions: The use of a pre-mortem CT scan and involvement of senior clinicians in the process of establishing cause of death will improve the accuracy and may obviate the need for a post-mortem in some patients. However, if a post-mortem is needed, the clinical notes should always be available for the pathologists and a senior member of the patient's team should attend the post-mortem to help accurate death certification.
