Abstract
Objectives: Autopsy plays an essential role in detecting diagnostic errors and the findings from autopsies have the potential to reduce future errors. However, there are few reports from Japan on diagnostic errors based on autopsy diagnoses. This study aimed to detail diagnostic errors in autopsy reports in Japan.
Methods: This descriptive study utilized the case report abstract database of the Japanese Society of Internal Medicine chapter meetings. Autopsy cases from 2002 to 2022 were included. We defined diagnostic errors as discrepancies in the primary cause of death between autopsy and clinical diagnosis. Diagnostic error cases were also categorized according to the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10). To observe trends, a chi-square test was conducted by dividing the 20 years of data into four groups.
Results: Among 1,213 autopsied cases, diagnostic errors occurred in 435 cases (35.9 %; 95 % confidence interval, 33.2-38.6 %). The most frequent category of autopsy-detected diagnostic error cases was neoplasms (147, 33.8 %), followed by infections (131, 30.1 %), and cardiovascular diseases (49, 11.3 %). Over the 20 years, the incidence of diagnostic errors neither increased nor decreased.
Conclusions: Diagnostic errors detected in 35.8 % of autopsy cases in Japan. Autopsy is an important quality indicator for identifying diagnostic error.
期刊介绍:
Diagnosis focuses on how diagnosis can be advanced, how it is taught, and how and why it can fail, leading to diagnostic errors. The journal welcomes both fundamental and applied works, improvement initiatives, opinions, and debates to encourage new thinking on improving this critical aspect of healthcare quality. Topics: -Factors that promote diagnostic quality and safety -Clinical reasoning -Diagnostic errors in medicine -The factors that contribute to diagnostic error: human factors, cognitive issues, and system-related breakdowns -Improving the value of diagnosis – eliminating waste and unnecessary testing -How culture and removing blame promote awareness of diagnostic errors -Training and education related to clinical reasoning and diagnostic skills -Advances in laboratory testing and imaging that improve diagnostic capability -Local, national and international initiatives to reduce diagnostic error
