The use of histology in 638 coronial post-mortem examinations of adults: an audit.
An audit was performed to determine the effectiveness of histological sampling of forensic post-mortem cases based on a review of three years' data, which comprised 638 adult autopsy cases. During the study period organs and tissues that appeared macroscopically normal and abnormal were extensively sampled. Histology was regarded as in some way contributory (providing, altering or confirming a cause of death) 53% of the time. The use of histology provided the cause of death in 49 (24%) of the 203 cases not given a cause of death after the completion of the macroscopic examination. When an interim cause of death had been supplied following the completion of the gross examination it was changed in 4.8% of cases, but there were no changes of the manner of death. The majority of the histological diagnoses or discrepancies involved the lungs and the heart. All diagnoses relevant to determining the cause of death would have been made if samples had been taken only from the left ventricle, right ventricle, coronary arteries, lungs, kidneys and brain with any tissue or organ that appeared abnormal macroscopically. A macroscopically identified abnormality that appeared to have been responsible for death was not sampled in 20 cases; consequently, more attention will be paid to sampling macroscopically abnormal tissues. As a result of this audit histology sampling practice has been revised and will be re-audited in the future.
