The Effect of a Case-finding App on the Detection Rate of Atrial Fibrillation in Primary Care Patients
The Effect of a Case-finding App on the Detection Rate of Atrial Fibrillation Compared With Opportunistic Screening in Primary Care Patients: Protocol for a Cluster Randomized Trial
Atrial fibrillation is a cardiac arrhythmia commonly encountered in a primary care setting. Current screening is limited to pulse palpation and ECG confirmation when an irregular pulse is found. Paroxysmal atrial fibrillation will, however, still be difficult to pick up. With the advent of smartphones, screening could be more cost-efficient by making use of simple applications, lowering the need for intensive screening to discover (paroxysmal) atrial fibrillation.
This cluster randomized trial will examine the effect of using a smartphone-based application such as FibriCheck® on the detection rate of atrial fibrillation in a Flemish general practice population. This study will be conducted in 22 primary care practices across the Flanders region of Belgium and will last 12 months. Patients above 65 years of age will be divided in control and intervention groups on the practice level. The control group will be subjected to standard opportunistic screening only, while the intervention group will be prescribed the FibriCheck® app on top of this opportunistic screening. The difference in detection rate between control and intervention groups will be calculated at the end of the study.
The investigators will use the online platform INTEGO for pseudonymized data collection and analysis, and risk calculation.
Smartphone applications might offer a way to cost-effectively screen for (paroxysmal) atrial fibrillation in a primary care setting. This could open the door for the update of future screening guidelines.

Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- The patient is 65 years or older.
- The patient has an electronic medical record (EMR) in the practice. This EMR contains all the patient information, for instance regarding medical history and medication and is managed by the general practitioner.
- If the patient will be prescribed the FibriCheck® app, he/she signs the relevant patient consent form
Exclusion Criteria:
- The patient has already been diagnosed with AF.
- The patient is already under anticoagulant therapy.
- The patient has a pacemaker. Active pacing during measurements influences the results obtained with the FibriCheck® app (26).
- The patient is unable to use the FibriCheck® application independently due to cognitive disorders, functional limitations, visual impairments…

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
No Intervention: Control group
In every cluster designated as a control group, patients aged 65 or older will be selected according to the inclusion criteria.
The difference here is that patients will be given the standard opportunistic screening instead: pulse palpation and a 12-lead ECG when an irregular rhythm is found.
This is current best practice.

|
Active Comparator: Intervention group
In every cluster designated as an intervention group, patients aged 65 or older will be selected according to the inclusion criteria.
Within this group, high-risk patients will be identified using the CHARGE-AF score, and will be prescribed the FibriCheck® app.
|
FibriCheck is a smartphone application that measures hearth rhythm using the phone's built-in camera.
It is able to detect aberrant rhythms, such as atrial fibrillation.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Detection rate of AF in patients 65 years and older
Time Frame: 4 weeks for each participant
|
The detection rate of AF in both the control and intervention group will be calculated after 4 weeks.
A significant difference in both groups will be noted.
Compared with previous studies of similar design (32-34), we will realistically assume a 2-fold increase in the detection rate of AF in the intervention group to be significant.
|
4 weeks for each participant

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Thromboembolic complications
Time Frame: 12 months
|
We will track incidence of transient ischemic attack or ischemic stroke during the study period, in addition to the eventual difference between both study populations.
|
12 months
|
Death
Time Frame: 12 months
|
We will keep track of all-cause mortality during the study period, as well as difference in mortality between control and intervention populations.
|
12 months
|
Compliance
Time Frame: 12 months
|
We will keep track of patient compliance during the study period (e.g.
minimum number of measurements with FibriCheck®).
