Brief Summary

This study will assess the benefits of using a mobile health application designed for shared decision aid in anticoagulation therapy in patients with Atrial Fibrillation (AF). The aim is to improve their treatment adherence and time in therapeutic International Normalized Ratio (INR) range. The results of this study have the potential to lead to a sustainable and resource-efficient strategy for better prevent thromboembolic events in patients with atrial fibrillation.

Detailed Description

Atrial Fibrillation is a common disease, with important burden on morbidity and mortality and a challenging management. Its incidence and healthcare costs have increased over the decades. One of the most important features of this arrhythmia is its stroke risk, which can be reduced with the use of anticoagulants. Deciding about anticoagulation therapy is complicated due to frequent competing comorbidities and potential harms of the therapy itself. To achieve better outcomes in preventing stroke, it is paramount that decisions about atrial fibrillation treatment be shared between providers and patients.

Mobile health is empowering individuals to assume a more active role in monitoring and managing their chronic conditions and therapeutic regimens. Also, health professionals are being provided with fast and point-of-care information, which can facilitate decision-making.

Therefore, this study will investigate the effects of an mHealth application idealized to aid shared decision and improve anticoagulation care in atrial fibrillation.

Adults with atrial fibrillation will be recruited from anticoagulation outpatient clinics and Basic Health Units and randomized to either (1) an intervention group in which the mHealth application will be used during the consultations or (2) a control group receiving the usual care with anticoagulation.

It is hypothesized that the intervention group will achieve better anticoagulation outcomes.

Conditions

Atrial Fibrillation; Anticoagulants; Circulating, Hemorrhagic Disorder

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: SINGLE

Study Groups

MATCh AFib

Participants assigned to the intervention group will have the support of the MATCh AFib application during the consultations with their physician and receive individual text messaging targeting knowledge about atrial fibrillation, medication adherence and monitoring during months 1-3.

Group Type: EXPERIMENTAL

MATCh AFib application

Intervention Type: BEHAVIORAL

The application comprehends five steps: (1) An educational video about how AF can cause stroke; (2) A calculator of risk scores (CHA2DS2-VASc, HAS-BLED and SAMe-TT2R2); (3) A screen with pictograms to allow better understanding of the scores by patients and to demonstrate how much each anticoagulant can decrease stroke risk or increase bleeding risk; (4) A summary about types of medications available, and (5) An output formulary in which the physician can register patient's contact to continue receiving information about atrial fibrillation and anticoagulation through SMS. Physicians can save patient's history of INR tests and previous doses of anticoagulation prescribed and also use a calculator to adjust the dose.

Standard Care

Participants assigned to the control group will complete measures at each time point and maintain care as usual (i.e., medical treatment, INR monitoring and consultations with their physician without mHealth support)

Group Type: NO_INTERVENTION

No interventions assigned to this group
