Validation of a score for predicting fatal bleeding in patients receiving anticoagulation for venous thromboembolism.

Background: The only available score to assess the risk for fatal bleeding in patients with venous thromboembolism (VTE) has not been validated yet.

Methods: We used the RIETE database to validate the risk-score for fatal bleeding within the first 3 months of anticoagulation in a new cohort of patients recruited after the end of the former study. Accuracy was measured using the ROC curve analysis.
