In any case, if there is bias, it will almost Paris 160 years ago, was greatly impressed by the value of certainly be in the direction of minimising the true the autopsy in advancing knowledge and in teaching. The autopsy rate. Parisian example led to postmortem examination of the of majority patients dying in hospital in the UK, in other Results and Comments European countries and in America. During the past quarter of a century, however, the hospital autopsy rate Table 1 shows that, of the 1,000 patients, 471 had an has fallen[l,2] and differences of opinion about the value autopsy, 260 (26 per cent) as part of routine hospital of the procedure[3-15] have led the Royal College of practice and 211 (21.1 per cent) at the request of the Pathologists to set up an enquiry into the matter.

The article sets out some information collected by the Medical autopsy rate of 47.1 per cent is much higher than the Services which was established the Study Group, by national rate (England about 27.3 per cent in 1975 and Royal College of Physicians in 1977, its terms of reference Scotland 23 per cent in 1974[ 1,2]) and this is thought to being to improve patient care in any way possible by be because all the 1,000 patients studied were under 50 means of medical audit. years of age.

The probable explanation is that all patients who had died, between the ages of one and 50 the Grampian deaths took place in the teaching hospital years, during 1978 and 1979. In addition, they were while the comparable hospitals in the Mersey and West requested to send a personal confidential comment on the Midlands Regions made virtually no contribution to our case, where appropriate, and in many instances they were study, almost all their cases coming from the District kind enough to give supplementary information and General Hospitals. The higher rate in the West Midlands clarify doubtful issues. In a number of cases coroners also as compared with the Mersey Region is due to the greater supplied copies of relevant reports. The total number of number of coroners' autopsies in the West Midlands, case notes received was 1,290, and here are the first 1,000 probably reflecting different attitudes by coroners in the considered from the point of view of autopsies.
