Post-Mortem Examination as a Quality Improvement Instrument.

BACKGROUND

Autopsies are considered an important quality assurance instrument in medicine, yet autopsy rates in many countries have been declining for many years. The proper role of the post-mortem examination in modern medicine is a matter deserving of study.

METHODS

This review is based on a selective search of the literature for publications on the role of autopsies as a quality assurance instrument.

RESULTS

Multiple studies have revealed substantial rates of discrepancy between pre- and post-mortem diagnoses, with reported rates lying in the range of 10% to 40%. The frequen- cy of so-called Goldman I erroneous diagnoses, i.e., those that are determined at autopsy and might have influenced the patient's survival, ranges from 2.4% to 10.7%. It can be as- sumed that the rate of serious diagnostic errors revealed by autopsy would fall if autopsy rates were to rise. Independently of the above-mentioned studies, a large-scale study of data from the period 1988-2008 revealed a decline in the rate of Goldman I erroneous diagnoses by more than half. The qualitative effects of autopsies, however, are difficult to measure. At present, imaging studies and minimally invasive or endoscopic diagnostic procedures can be performed post mortem as well, but the available studies show that these methods do not yet suffice to enable a coherent pathogenetic classification of disease processes.

CONCLUSION

Autopsies should still be performed in the interest of quality assurance in medicine. Uniform standards in the performance and reporting of autopsies could lead to im- provement in the use of the data acquired through them.
