Bleeding rates in Veterans Affairs patients with atrial fibrillation who switch from warfarin to dabigatran.
This study evaluated the relative risks of any, gastrointestinal, intracranial, and other bleeding for Veterans Affairs patients who switched to dabigatran after at least 6 months on warfarin. It found that among veterans with atrial fibrillation who switched to dabigatran, dabigatran increased the risk of gastrointestinal hemorrhage by 54% and was not associated with rates of other bleeding or death.

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.

Prescribing warfarin at discharge for heart failure patients: findings from the Get With The Guidelines-Heart Failure Registry
The researchers used data from a heart failure (HF) registry to determine the prevalence and variation, as well as patient characteristics, in warfarin prescription among real-world HF population. They found that warfarin was prescribed at discharge for more than 1 out of 10 patients hospitalized for HF without evident indications or contraindications for anticoagulation.
