Multicenter Study
Prescribing of oral anticoagulants in the emergency department and subsequent long-term use by older adults with atrial fibrillation.
Patients with atrial fibrillation frequently seek emergency care. Rates of guideline-concordant oral anticoagulant therapy for stroke prevention are suboptimal in the community. We assessed the association between prescribing of oral anticoagulants in the emergency department (relative to referral to a longitudinal care provider for treatment initiation) and long-term use of oral anticoagulants. ⋯ In patients with atrial fibrillation who were eligible for stroke prevention, prescribing an oral anticoagulant in the emergency department was associated with substantially higher long-term use of oral anticoagulants compared with deferring to the longitudinal care provider to initiate this therapy. Physicians working in the emergency department should consider initiating oral anticoagulation in eligible patients who are being discharged to home.
