Bleeding risk calculators - HAS-BLED (atrial fibrillation) and IMPROVE (VTE prophylaxis for inpatients) Important notes: • No bleeding risk tools have been validated for VTE treatment, only for prophylaxis and atrial fibrillation • Observational studies suggest net clinical benefit of anticoagulation even with very high bleeding risk • No RCTs exist demonstrating benefit of withholding anticoagulation based on high bleeding risk #HASBLED #IMPROVE #Bleeding #Risk #Scores #Calculators #Anticoagulation #Factors #Hematology #Diagnosis
