The ORBIT bleeding score: a simple bedside score to assess bleeding risk in atrial fibrillation.
The researchers sought to develop and validate a novel bleeding risk score using routinely available clinical information to predict major bleeding in a large, community-based in atrial fibrillation (AF) population. They concluded that their five-element ORBIT bleeding risk score had better ability to predict major bleeding in AF patients when compared with HAS-BLED and ATRIA risk scores.

Effect of the 2014 atrial fibrillation guideline revisions on the proportion of patients recommended for oral anticoagulation.
Researchers assessed the potential effect of a new guideline for atrial fibrillation (AF) by comparing the proportion of patients with AF recommended for oral anticoagulation (OAC) under the 2011 and 2014 guidelines. They found that two-thirds of patients with AF who were previously not recommended for OAC are newly recommended under the 2014 guideline. They advised future studies evaluating longitudinal changes in anticoagulation treatment patterns and outcomes among patients reclassified by the new guidelines.

Effectiveness and safety of dabigatran and warfarin in real-world US patients with non-valvular atrial fibrillation: a retrospective cohort study.
The researchers compared the effectiveness and safety of the new oral anticoagulant, dabigatran, with warfarin in clinical practice among a large nationally representative retrospective cohort of commercially insured patients in the United States. They found that compared with warfarin, dabigatran was associated with a lower risk of ischemic stroke or systemic embolism, hemorrhagic stroke, and acute myocardial infarction.

Physician practices regarding contraindications to oral anticoagulation in atrial fibrillation: findings from the Outcomes Registry for Better Informed Treatment of Atrial Fibrillation (ORBIT-AF) registry.
This study describes the frequencies of and factors associated with oral anticoagulation (OAC) contraindications in clinical practice for patients with atrial fibrillation (AF). Contraindications to OAC therapy among patients with AF are common but subjective. Many patients with reported contraindications were receiving OAC, suggesting that the perceived benefits outweighed the potential harm posed by the relative contraindication.
