Interventions to Improve Emergency Department-Related Transitions in Care for Adult Patients With Atrial Fibrillation and Flutter

Presentation, Treatment and Long-Term Outcomes of a Multidisciplinary Acute Atrial Fibrillation Pathway: A 12-Month Follow-Up Study

AIM

Atrial fibrillation/flutter (AF/AFL) is associated with high rates of emergency department (ED) visits and acute hospitalisation. A recently established multidisciplinary acute AF treatment pathway seeks to avoid hospital admissions by early discharge of haemodynamically stable, low risk patients from the ED with next-working-day return to a ward-based AF clinic for further assessment. We conducted a preliminary analysis of the clinical outcomes of this pathway.

METHODS

We retrospectively reviewed clinical records of all patients assessed at the AF clinic at Christchurch Hospital over a 12-month period. Data related to presentation, patient characteristics, treatment, and 12-month outcomes were analysed.

RESULTS

A total of 143 patients (median age 65, interquartile range: 57-74 years, 59% male, 87% European) were assessed. Of these, 87 (60.8%) presented with their first episode of AF/AFL. Spontaneous cardioversion occurred in 41% at ED discharge, and this increased to 73% at AF clinic review. Electrical cardioversion was subsequently performed in 16 patients (11.2%), and 16 (11.2%) ultimately required hospital admission (eight to facilitate electrical cardioversion). At a median of 1 day, 83.9% were discharged from the AF clinic in sinus rhythm. During 12-month follow-up, there were 25 AF-related hospitalisations (20 patients, 14%) and one patient underwent electrical cardioversion; additionally, one patient had had a stroke and eight had bleeding complications giving a combined outcome rate of 6.3%.

CONCLUSION

Utilising a rate-control strategy with ED discharge and early return to a dedicated AF clinic can safely prevent the majority of hospitalisations, avert unnecessary procedures, and facilitate longitudinal care.
