SAFER study


The SAFER Trial – Screening for Atrial Fibrillation with ECG to Reduce stroke

Claremont is taking part in a programme of research investigating screening to detect atrial fibrillation, a heart condition responsible for one in ten stroke

Aim of the Study

To answer the question: is screening for Atrial Fibrillation effective and cost effective in reducing stroke and other key outcomes compared to current practice?

Can I take part?

We will identify patients who are likely to be eligible to take part. We are looking for patients who are:

Aged 70 or over

Not currently taking blood thinning (anticoagulant) medication

Important notes:

You can still take part if you are taking aspirin or clopidogrel. These are anti-platelet medications not anticoagulant medication – they thin the blood in a different way.

If you think you already have AF you can still take part in the trial so long as you are not currently taking blood thinning (anticoagulation) medication like rivaroxaban, edoxaban, apixaban, warfarin. All other medication is okay.

But, what does the trial entail?

We have sent out invitations to people who may be eligible to explain more about the study. Those people may have returned a consent form to say they are happy to take part. They will then be sent a hand held device. They will be shown how to use this daily for three weeks to pick up a heart tracing. This si then sent back to the study team and the participant and GP practice are informed of the result. If Atrial fibrillation is found the GP will contact the participant to discuss things further.

This study is closed to recruitment but many of our patients are currently taking part in it.
