An extensive literature documents substantial rates of missed diagnoses that are discovered at autopsy, including diagnoses that likely affected issue (1-4) Physicians generally have attributed these findings to selection bias. With the national autopsy rate for nonforensic deaths having fallen to roughly 5 percent (5) physicians may petition autopsy precisely in those cases likely to reveal important novel diagnoses.

In answer to a request by the association of American Pathologists and supplyed by the Agency for Healthcare Research and Quality, we systematically reviewed the literature to assess time inclines in autopsy-detected diagnostic errors and to specifically address the question of whether clinical selection bias explains the persistent error rates that are reported flat in contemporary autopsy series. (6)

We reviewed more than 200 studies of autopsy-detected errors in clinical diagnosis, (6) 53 of which met prespecified inclusion criteria. (12) Discrepancies between clinical and autopsy diagnoses were defined as "major errors" when a clinically missed diagnosis involved a principal underlying disease or primary cause of death; and they were defined as "class I errors" when the patient might have survived to hospital discharge if antemortem diagnosis had occurred

The 53 studies included any that spanned a 40-year period (1959 to 1999) and reported major and class I error rates of 235 percent (range, 41 to 498 percent) and 90 percent (range, naught to 20.7 percent), respectively. Despite steady declines in major and class I error rates, typical U institutions in the year 2000 observ a major error rate ranging from 84 to 244 percent based upon autopsy rates ranging from 100 percent (the extrapolated farthest at which clinical selection is eliminated) to 5 percent (roughly the national average). The same range of autopsy rates would make class I error rates of 41 to 67 percent (7)

Although we used the confine "error" (in keeping with the security of the autopsy literature), the discrepancies between clinical and autopsy findings combine loyal errors with difficult cases. forward the other hand, it is worth noting that these error rates do not include les dramatic if it be not that potentially important missed diagnoses, nor do they address delayed diagnosis. Diagnoses exposeed at any time before death were considered as clinically recognized even if earlier detection would have improved outcome

These findings have important implications, especially for primary care physicians, who are most numerous likely to be caring for patients at the completion of life. Autopsy remains a diagnostic gold standard; failure to establish a cause of death is estimated to be les than 5 percent in adult deaths. (6)

With regard to inpatient deaths, it is tempting to assume that the barrage of sophisticated diagnostic standards readily available in contemporary hospitals obviates the ne for autopsy. However, hospitalized patients accounted for the overwhelming majority of patients in the studies included in our analysis. Moreover, clinicians have merely a modest ability to identify inpatient deaths in which autopsy will or will not yield important novel information. (6) With regard to outpatient deaths, the importance of autopsy is presumably greater, smooth in cases of apparently clear-cut rapid cardiac death. (8)

Physicians may worry about the possibility of malpractice claims, moreover the existing literature suggests that autopsy helps physicians more oftentimes than not. (6) In fact, we establish no reported case of malpractice action initiated solely onward the basis of unexpected diagnostic errors or complications bring to lighted at autopsy. In a newly come study assessing the role of autopsy information in malpractice cases, it was build that defendant physicians usually were exonerated, and observance of the standard of care was imagineed more important in determining medical negligence than accuracy of clinical diagnosis. (9)

Although family members of a deceased patient sometimes worry about the potential issue of autopsy on funeral arrangements, it has virtually no result on any aspect of a funeral. With appropriate notification to the pathologist, autopsy can be complet within 24 to 48 hours, and incisions forward the face and head are difficult to find even by the trained student creating no problems for open-casket ceremonies. Unfortunately, the same issue of which clinicians in community practice ne to remain aware is cost--in an regions, families must pay for nonforensic autopsies. on a level in such regions, though, academic center perform independent autopsies and may accept referrals from other hospitals, because dwindling autopsy rates have made it difficult for pathology programs to provide access to sufficient cases for trainees.

Many physicians be wrought up uncomfortable recommending autopsy to family members, (10) presumably because of lack of experience because autopsy rates have fallen to of that kind low levels. (5) Criteria for autopsy referral are determined according to the county or state. At the hospital even each hospital is required to include autopsy criteria as part of its policy. As with advance directives and selections for end-of-life care, autopsy discussions are generally les difficult than physicians initially imagine and can be rewarding, as patients expres feelings about their illness and goals of care for the time they have left
