Abstract

Use of direct-acting oral anticoagulants for patients with nonvalvular atrial fibrillation (NVAF) in skilled nursing facilities (SNFs) is increasing. Rivaroxaban is commonly used in this setting as an alternative to warfarin, based on comparable or increased efficacy in preventing stroke and a similar or lower risk of major bleeding. The aim of this study was to compare healthcare resource utilization (HCRU) and costs between NVAF patients receiving rivaroxaban or warfarin in SNFs. This retrospective study examined de-identified claims from Optum® Clinformatics® Extended Data Mart (1 January 2013-31 December 2017). Eligible patients had an AF diagnosis, were prescribed rivaroxaban or warfarin during an SNF stay, and had one or more such prescriptions filled in the 6 months preceding the stay. Patients were excluded if they received another oral anticoagulant or had evidence of valvular heart disease, mitral stenosis, or organ/tissue transplant. HCRU, mean number of events, and all-cause healthcare costs during the index SNF stay were reported. Results were also reported on a per-patient-per-month (PPPM) basis. Exploratory analyses at different time periods were also conducted. Overall, 4423 rivaroxaban patients and 22,796 warfa...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
