Study to Evaluate the Use of Direct Oral Anticoagulants in UK Clinical Practice For Patients With a First Stroke Attributable to Nonvalvular Atrial Fibrillation

A Descriptive Non-interventional Study to Evaluate the Use of Direct Oral Anticoagulants in UK Clinical Practice for Patients With a First Stroke Attributable to Nonvalvular Atrial Fibrillation

National Institute of Health and Care Excellence (NICE) guidance recommends anticoagulation for stroke prevention in high risk patients with nonvalvular atrial fibrillation (AF).

Early evidence suggest that patients with atrial fibrillation (AF) who do not receive anticoagulation are more likely to experience a stroke. However, the characteristics of patients experiencing a first AF-related stroke in real-world settings, who have not been receiving anticoagulation, have not been well documented.

It is unclear how the direct anti-FXa oral anticoagulants have been used within real world practice since the introduction of edoxaban in 2015.

Visão geral do estudo

Descrição detalhada

This non-interventional study will focus specifically on the patient characteristics, management pathways, and patient reported experiences associated with real world use of three direct anti-FXa oral anticoagulants (DOAC) commonly used within United Kingdom clinical practice; apixaban, rivaroxaban and edoxaban.

The primary objective will describe the demographics, clinical characteristics and medical history of patients presenting with a first ischaemic stroke with AF who have not received anticoagulation (for any reason) in the 12 months prior to stroke, by type of anticoagulant treatment subsequently prescribed for secondary prophylaxis of stroke.

Secondary objectives of the study will describe management pathways of patients initiated on DOACs (apixaban, edoxaban or rivaroxaban) for secondary prophylaxis of stroke, including timing and reasons for any dose changes or treatment switches to alternative anticoagulants; describe hospital resource use and clinical assessments associated with DOAC treatment for secondary prophylaxis of stroke; describe real world patient-reported adherence to DOACs for secondary prophylaxis of stroke; and describe patient experience and treatment satisfaction for patients receiving DOAC therapy for secondary prophylaxis of stroke.

População do estudo

For the wider retrospective study (Group 1 patients), potentially eligible participants will be identified by members of the direct care team from local department databases. Eligible participants will be selected in consecutive chronological order by the direct care team according to the date of stroke diagnosis until the required sample size or the center-specific recruitment target is reached, over a one-year recruitment period.

The first 50 eligible and consenting participants initiated on either apixaban, edoxaban or rivaroxaban at any of the study centers during the 28 month recruitment period will also be included in the prospective component of the study.

  • Participants aged 18 years or over at time of first stroke

For group 2 patients:

* Participants initiated on apixaban, edoxaban or rivaroxaban after their first stroke

Exclusion Criteria:
