Assessment of misdiagnosis in small animal intensive care patients using the Modified Goldman criteria

Abstract

AbstractThe postmortem examination can be used as a means of quality control for clinical diagnoses. A retrospective study on 300 dogs and cats that had been admitted to a small animal intensive care unit was performed comparing the clinical and postmortem findings, using the Modified Goldman criteria. All patient files were reevaluated for clinical diagnoses and all postmortem material was reevaluated for pathological diagnoses. After this, the Modified Goldman criteria were applied to score the discrepancies between them, and factors associated with the occurrence of an undiagnosed major unexpected finding were analyzed. The postmortem examination revealed additional findings in 65% of the cases. Major discrepancies, defined as those affecting treatment and possibly outcome of the patient, were present in 21.3% of the cases. The most frequently missed diagnoses detected at necropsy were pneumonia of various etiologies, meningitis/meningoencephalitis, myocarditis and generalized vasculitis. A shorter ICU stay was associated with increased odds of a major discrepancy. Conditions affecting the urinary or gastrointestinal system were negatively associated with major discrepancy.
