Key result
Among 245 patients presenting to the emergency department with new-onset atrial fibrillation who were indicated for anticoagulation, 46.5% were discharged without initiating therapy.
Why the study?
Patients with AF have an increased risk of stroke and systemic thromboembolism, and the study assessed how many patients with new-onset AF are appropriately initiated on oral anticoagulation during an ED visit.
What percentage of patients with new-onset atrial fibrillation indicated for oral anticoagulation are discharged from the emergency department without it?
Observational (n=380)
What percentage of patients with new-onset atrial fibrillation indicated for oral anticoagulation are discharged from the emergency department without it?
A significant proportion (46.5%) of patients with new-onset atrial fibrillation who are indicated for anticoagulation are discharged from the emergency department without being prescribed it, highlighting a gap in care.
May indicate underuse of indicated AC in ED new-onset AF; leaves open whether targeted interventions improve uptake.
Patients with atrial fibrillation (AF) have an increased risk of stroke and systemic thromboembolism. Diagnosis of AF is commonly encountered in the emergency department (ED). The purpose of this study was to assess the number of patients with new-onset AF appropriately initiated on oral anticoagulation (AC) during their ED encounter. This retrospective analysis included patients discharged from the ED from July 2016 to July 2021 with a new diagnosis of AF. Patients were excluded if they were on AC before admission. The major endpoint was to identify the percentage of patients discharged from the ED without initiating AC. Minor endpoints included the average CHA2DS2-VASc scores and the reason for not initiating AC. A total of 380 patients were included in the final analysis. Of the 245 patients found to be indicated for AC, only 131 patients (53.5%) were initiated on AC and 114 patients (46.5%) were discharged without initiating AC. Almost half of the patients who presented to the ED with a new diagnosis of AF and indicated for AC were discharged without AC.

Habeeb et al. (2023) conducted an observational in New-onset atrial fibrillation (n=380). Oral anticoagulation initiation vs. Discharge without initiating oral anticoagulation was evaluated on Percentage of patients discharged from the ED without initiating oral anticoagulation. Among 245 patients presenting to the emergency department with new-onset atrial fibrillation who were indicated for anticoagulation, 46.5% were discharged without initiating therapy.
