Sensibilité des codes diagnostiques saisis dans le cadre du programme de médicalisation des systèmes d'information pour l'identification des cas de maladie thrombo-embolique veineuse

Abstract : Objective: To estimate the sensitivity of ICD-10 hospital discharge diagnosis codes for identifying deep vein thrombosis (DVT) and pulmonary embolism (PE). Study design and Setting: We compared predefined ICD-10 discharge diagnosis codes with the diagnoses that were prospectively recorded for 1375 patients with suspected DVT or PE who were enrolled at 25 hospitals in France. Sensitivity was calculated as the percentage of patients identified by predefined ICD-10 codes among positive cases of acute symptomatic DVT or PE confirmed by objective testing. Results: The sensitivity of ICD-10 codes was 58.0% (159/274; 95% confidence interval [95% CI], 51.9-64.1) for isolated DVT and 88.9% (297/334; 95% CI, 85.6-92.2) for PE. Depending on the hospital, the median values for sensitivity were 57.7% for DVT (interquartile range, 48.6-66.7; intracluster correlation coefficient, 0.02; P=0.31) and 88.9% for PE (interquartile range, 83.3-96.3; intracluster correlation coefficient, 0.11; P=0.03). The sensitivity of ICD-10 codes was lower for surgical patients and for patients who developed PE or DVT while hospitalized. Conclusions: ICD-10 discharge diagnosis codes yield satisfactory sensitivity for identifying objectively confirmed PE. A substantial proportion of DVT cases are missed when using hospital discharge data for complication screening or research purposes.
