In addition to warfarin, there are four non-vitamin K antagonist oral anticoagulants (NOACs) available for stroke prevention in non valvular atrial fibrillation (NVAF). There are limited data on the comparative risks of major bleeding among newly anticoagulated NVAF patients who initiate warfarin, apixaban, dabigatran, or rivaroxaban, when used in 'real(More)
This retrospective analysis investigated the impact of baseline clinical characteristics, including atrial fibrillation (AF), on hospital discharge status (to home or continuing care), mortality, length of hospital stay, and treatment costs in patients hospitalized for stroke. The analysis included adult patients hospitalized with a primary diagnosis of(More)
PURPOSE This study evaluated the effects of concomitant pravastatin and paroxetine use on the incidence of Type 2 Diabetes Mellitus (T2DM). METHODS A new-user retrospective cohort design was employed using data selected from US health insurance claims databases (OptumInsight and MarketScan) between July 1, 2002, and December 31, 2009. Patients included(More)
BACKGROUND Limited data are available about the real-world safety of non-vitamin K antagonist oral anticoagulants (NOACs). OBJECTIVES To compare the major bleeding risk among newly anticoagulated non-valvular atrial fibrillation (NVAF) patients initiating apixaban, warfarin, dabigatran or rivaroxaban in the United States. METHODS AND RESULTS A(More)
OBJECTIVES To identify factors associated with all-cause discontinuation (patient discontinued on their own or physician discontinuation) of oral anticoagulants (OACs) among nonvalvular atrial fibrillation (NVAF) patients. STUDY DESIGN Retrospective cohort study. METHODS We analyzed the MarketScan claims database from October 2009 to July 2012. Adult(More)

The ARISTOTLE trial showed a risk reduction of stroke/systemic embolism (SE) and major bleeding in non-valvular atrial fibrillation (NVAF) patients treated with apixaban compared to warfarin. This retrospective study used four large US claims databases (MarketScan, PharMetrics, Optum, and Humana) of NVAF patients newly initiating apixaban or warfarin from(More)
AIM While bleeding is a well-known complication of warfarin use and is thought to be a contributory cause of treatment discontinuation, studies quantifying this association are limited. The objective of this study was to quantify the association between bleeding events and subsequent warfarin discontinuation in patients with nonvalvular atrial fibrillation(More)
BACKGROUND Prophylaxis for venous thromboembolism after total knee replacement (TKR) is standard of care. Two enoxaparin regimens are approved for thromboprophylaxis, one in the United States (30 mg twice daily [bid]) and another in the rest of the world (40 mg once daily [qd]). Data on frequency of utilization of these 2 regimens at discharge from US(More)
