MedPage Today (7/13, Neale) reported that "a score based on five clinical variables performs well for predicting the risk of warfarin-associated hemorrhage in patients with atrial fibrillation," according to a study published in the Journal of the American College of Cardiology. Investigators found that "the model, which included anemia, severe renal disease, an age of 75 or older, prior hemorrhage, and hypertension, outperformed six other published and validated risk scores." The investigators reported that "the rate of warfarin-associated major hemorrhage ranged from 0.4% per 100 patient-years in the low-risk group to 5.8% in the high-risk group."
