Description of intervention(s) / exposure
The aim of this study is to characterise hospital based health care resource utilisation in a cohort of individuals with atrial fibrillation. The cohort of individuals comprises of participants who presented to the emergency departments of three hospitals over a one year period (2013-2014) primarily due to atrial fibrillation. Emergency department presentations and hospital admissions over an approximate four year follow up period (ranging from 2013-2018) will be recorded with a view towards characterising reasons for re-presentations to the emergency department and hospital admissions. This information will be obtained retrospectively by electronic medical review. The management of atrial fibrillation will be explored including the use of rate and rhythm control therapies and appropriate use of oral anticoagulation to reduce stroke risk. Factors predictive of re-presentation and hospitalisation will be examined.

Outcomes
Primary outcome [1] 308129 0
The primary outcome measure will be to characterise reasons for emergency department re-presentations and/or hospital admissions in a cohort of individuals with AF. These will be characterised as related to: 1: atrial fibrillation 2: other cardiovascular causes 3: all other causes. This is a composite endpoint. Data will be collected by retrospective electronic medial review.
Timepoint [1] 308129 0
Over an approximate four year follow up time period. This time period ranges from 2013-2018.
Primary outcome [2] 308172 0
To determine factors predictive of re-hospitalisation for atrial fibrillation
Timepoint [2] 308172 0
Over an approximate four year follow up period (ranging from 2013-2018).
Secondary outcome [1] 354148 0
To determine hospital based management of atrial fibrillation, including the use of rate and rhythm control strategies, and the appropriate use of oral anticoagulation to reduce stroke risk.
Timepoint [1] 354148 0
Over an approximate four year follow up period (ranging from 2013-2018).

Statistical methods / analysis
The study sample consists of all individuals presenting to the emergency department of participating hospitals (for the HELP AF study) over a one year period. All individuals with a principal diagnosis of atrial fibrillation were eligible for inclusion. Descriptive analyses will be used to examine reasons for emergency department re-presentations and admissions over the follow up period. A logistic regression model will be used to examine factors predictive of re-presentation or admission to hospital. Descriptive analyses will be employed to examine the use of rate and rhythm control therapies and appropriate use of oral anticoagulation.

Summary
Brief summary
The aim of this study is to examine reasons for re-presentation to emergency departments or admissions to hospital in a cohort of individuals with atrial fibrillation (AF). The use of treatment for AF, including rate and rhythm controlling strategies, and blood thinning medications (anticoagulation) to reduce the risk of stroke will also be explored. Factors associated with emergency department re-presentations and/or hospital admissions will also be examined.
