The revised Geneva score is a fully standardized clinical decision rule (CDR) in the diagnostic workup of patients with suspected pulmonary embolism (PE). The variables of the decision rule have different weights, which could lead to miscalculations in an acute setting. We have validated a simplified version of the revised Geneva score.

Data from 1049 patients from 2 large prospective diagnostic trials that included patients with suspected PE were used and combined to validate the simplified revised Geneva score. We constructed the simplified CDR by attributing 1 point to each item of the original CDR and compared the diagnostic accuracy of the 2 versions by a receiver operating characteristic curve analysis. We also assessed the clinical utility of the simplified CDR by evaluating the safety of ruling out PE on the basis of the combination of either a low-intermediate clinical probability (using a …
