Comparison between clinical and autopsy diagnoses in a cardiology hospital

Background: A few recent studies have evaluated diagnostic accuracy by comparison between clinical and autopsy diagnoses in a hospital specialising in cardiology. Methods: 406 consecutive autopsy cases during 2 years were studied. Patients were aged 47.4±28.4 years; 236 (58.1%) were men and 170 (41.9%) women. Diagnostic comparison was categorised in classes I to V (I, II, III and IV: discrepancy in decreasing order of importance regarding therapy and prognosis; V: concordance). Categorisation was ranked on the basis of the highest degree of discrepancy. Statistical analysis was performed with the Χ 2 test and stepwise logistic regression. Results: Each age increase of 10 years added 16.2% to the risk of the diagnostic comparison to be categorised in classes I and II (major discrepancy) in comparison to classes III, IV and V (OR 1.16, 95% CI 1.07 to 1.27, p Conclusion: Age and hospital ward influenced the distribution of diagnostic discrepancy or concordance between clinical and autopsy diagnoses. The lower discrepancy rate for myocardial infarction and infective endocarditis may be related to the fact that the study was carried out in a specialist hospital.
