Many clinicians are unaware of these events, which may come to have wide-ranging detrimental effects. One possible cause is the lack of training of junior medical staff in obtaining consent for postmortem examination, though other factors are also important.
KEY WORDS: audit, autopsy, decline, diagnostic errors, post-mortem examination IntroductionPost-mortem examinations (PMs) have been important in the development of modern medicine, their value having been recognised for about two centuries. 1 PMs of hospital patients should continue to be valuable in clinical governance by providing an independent means of checking the accuracy and completeness of ante-mortem diagnoses and an assessment of the effects of treatment. Indeed, a programme of well-conducted clinical PMs forms the heart of a method of quality assessment of medical diagnostics. 2 Additional benefits include: a greater understanding of disease and its management; the description of new diseases or the effects of new treatments; 3 the retention of tissue and organs for teaching and research; the training of medical students, 4 junior doctors and histopathologists; 3 and continuing professional development of clinical consultants. They also increase awareness of the multiplicity of conditions which many patients (particularly the elderly) have and of the level of uncertainty -'necessary fallibility' -in medical practice. [4][5][6] Moreover, the greater understanding following PM may also be beneficial for the family, 7 something that should not be overlooked when the recently bereaved are counselled by clinicians. This is particularly the case in pregnancy loss and possible inheritable disease, where there may be important implications for other family members.It has long been recognised that the clinical (consented) PM is in decline 1,5,[8][9][10][11][12] and, if not dead, then terminally ill. 13 In Britain, this decline appeared to start in the 1950s 8,12,14 and has continued ever since. There are, however, few recent data to support this contention, and the effects of the publicity following events in Bristol and Liverpool have not been explored. Here we describe the recent consented PM rate for patients dying in the Norfolk and Norwich University Hospital NHS Trust (NNUH), which has 989 beds and serves a population of at least half a million, and the nature of the consent given. We also explore clinicians' opinions about the numbers of PMs they request and how they obtain the necessary consent.
Methods
Review of the numbers and extent of consented post-mortem examinationsWe examined the records of the mortuary and Department of Histopathology for the period 1 January 1996 to 31 December 2003 to determine the number of adults dying in NNUH, the number undergoing consented PM, and the extent of the examination permitted by that consent. From these data we derived the clinical PM rate (number of consented PMs divided by the number of deaths, expressed as a percentage). The number of stillbirths and perinatal deaths, the number of consented PMs undert...
