Consecutive autopsies on an internal medicine service

Clinical and needle autopsy correlation evaluation in a tertiary care teaching hospital: a prospective study of 50 cases from the emergency department

With gradual fall in autopsy all over the world in recent years, the present study aimed to assess the accuracy of clinical diagnosis and efficacy of needle autopsy from the emergency department. Fifty deceased patients, who died in the emergency department during a period of 1 year, were subjected to needle autopsy of the major viscera, using spring-loaded automated biopsy gun, and the findings were correlated with clinical diagnosis. The deceased patients were in the age range of 12 to 80 years (mean [SD], 50.48 [18.41] years). The tissues yielded from various organs were as follows: lungs, 90%; liver, 82%; kidney, 48%; heart, 28%; spleen, 22%; and pancreas, 18%. Before death, 86 clinical diagnoses were recorded, of which 21 (24%) (eg, metabolic encephalopathy, cardiac arrhythmia, diabetic ketoacidosis) were impossible to verify on needle autopsy. A total of 48 new diagnoses, missed by physicians, were revealed by needle autopsy. The most frequently missed diagnoses were liver fatty change (19 patients) and pneumonitis (11 patients). Other frequently missed diagnoses were chronic hepatitis (3 patients) and cancer (2 patients: 1 lung squamous cell carcinoma and 1 lung adenocarcinoma). Major diagnostic errors (Goldman classes I and II) were noted in 16 (32%) of 50 cases. Needle autopsy can be a better alternative in the absence of conventional autopsy.

High rate of discordance between clinical and autopsy diagnoses in blood and marrow transplantation

We analyzed autopsies performed in a Canadian blood and marrow transplantation (BMT) program. We aimed to assess variables that predict the performance of an autopsy, whether rates of autopsy are changing, and the rate of discordance between clinical and autopsy diagnoses. All deceased adult patients from January 1990 to December 2004 were reviewed. Autopsy rates were compared to a large teaching hospital. Of 476 myeloablative BMT patients, 225 died and 48 (27%) underwent autopsy. Autopsy was more likely in patients dying: <100 days post-BMT, in the intensive care unit, after allografting, and on weekends. Autopsy rates among BMT patients declined during the three time periods (1990-1994, 1995-1999, 2000-2004). The autopsy rate at the teaching hospital showed a similar downward temporal trend. Major and minor disagreements at autopsy were present in 16 (34%) and 14 (30%) of cases, respectively. There was no change in discordance rates over time. Thus, despite advances in diagnostic procedures, high levels of disagreement between clinical and autopsy diagnoses for BMT patients persist as autopsy rates decline. We recommend that the autopsy regains its role as a valuable investigation. This may become especially relevant in an era where patients with medical comorbidities are undergoing reduced-intensity BMT.

Use of autopsy in general surgery: a comparison of practice and opinion

OBJECTIVE

To examine current practice regarding autopsy requests and assess consultant opinion regarding the role of autopsy in a general surgical department.

METHODS

One hundred deaths that occurred in a teaching hospital general surgical department, over a 2-year period, were randomly selected. After review of the hospital notes, a brief summary of each admission was distributed to all 13 consultant general surgeons in the department. Surgeons were asked to comment whether each case should have been discussed with the coroner, whether a coroner's autopsy should have been carried out, whether a hospital post-mortem examination should have been carried out and whether it would be appropriate to complete a death certificate without a post-mortem examination. Surgeon responses were compared with actual outcomes, and both were analysed for predictors of variation in practice.

RESULTS

The majority of patients were elderly (median age 79 years, 49% >80 years), were admitted acutely (92%) and did not undergo an operation (73%). Thirty-three patients died of cardiac or respiratory causes. Patients who had undergone a recent operation were more likely to be referred to the coroner (P < 0.001) and more likely to undergo coroner's autopsy (P = 0.011). Older patients and those admitted from a rest home were less likely to be referred to the coroner (P < 0.001 and 0.02, respectively) or undergo coroner's autopsy (P = 0.002 and 0.011, respectively). The survey predicted more referrals to the coroner (44 vs 30, P = 0.001) and more hospital autopsies (21 vs 2, P < 0.001) and that the treating doctor would complete the certificate of death less often than actually happened (79 vs 91, P = 0.004). The survey suggested that surgeons were more likely to complete the certificate of death in patients with active malignancy (P = 0.01), but this was not observed in practice.

CONCLUSIONS

General surgeons consider autopsy to be necessary more often than that is taking place in practice in our institution. The continued decline in autopsy rates may compromise the safety and quality of the service provided by general surgeons and result in a gap in the education of surgeons and trainees.

Reversing the slow death of the clinical necropsy: developing the post of the Pathology Liaison Nurse

The adult clinical necropsy has been declining for many years and is nearing extinction in many hospitals. In Norwich, to prevent this from occurring, a Pathology Liaison Nurse (PLN) was appointed, resulting in a modest reversal of the trend. In 2005, the number of adult clinical necropsies increased to 58 (clinical necropsy rate = 2.4%) from its nadir of 34 (clinical necropsy rate = 1.4%) in 2003. Moreover, consent is now much more likely to be full and to allow histopathological and other studies. The PLN ensures that consent is properly and fully obtained, in line with current legislation. She also plays an important role in arranging for feedback to be given by clinicians to the families after the examination, and in teaching and training Trust staff about death, bereavement, and related matters. This paper describes how the role of PLN was established and evaluated, and gives details of the current state of the adult clinical necropsy in Norwich.
