Abstract
BACKGROUND AND OBJECTIVES: In this study, coroner's autopsy reports were used to validate results obtained from respiratory virus screening of swabs rather than tissue collected during autopsy in cases of adult death of unknown cause. STUDY DESIGN: Coroner's autopsy samples collected for respiratory virus screening between October 2010 and February 2011, were identified. Autopsy reports were requested from cases positive for a virus. Each report was reviewed to correlate findings at autopsy with the virology result and to determine whether the virus found was listed as a contributing factor in the death. RESULTS: Sixty-four coroner's autopsy cases were identified and a respiratory virus was found in 25 cases. Influenza A(H1N1)pdm09 virus was found most frequently, then RSV and influenza B with a dual influenza A and B infection and a parainfluenza type 1. Where multiple sites were swabbed, the virus was detected in all sites. Autopsy reports for 12 cases were obtained each reporting findings consistent with respiratory infection. Influenza A was always listed as a contributing factor in the death whereas RSV was listed once and influenza B was omitted in one case. The quality of the reports was variable and full histology was less likely to be performed in the elderly. CONCLUSIONS: While coroner's reports supported the use of swabbing rather than tissue collection, the lack of consistency and omission of the virology findings as contributing factors to death means that the burden of viruses on mortality statistics will remain under-estimated particularly in the elderly.
