NCT05898165

Brief Summary

The purpose of this study is to trial a new intervention - risk-guided AF screening using an EHR-based risk score and remote ECG monitoring process - and to characterise individuals at elevated predicted AF risk.

Outcome Measures

Primary Outcomes (3)

  • To determine whether detection rates of AF during ECG monitoring are higher amongst participants identified as higher risk of AF, compared with those identified as lower risk

    Rate ratio of AF detection rates during ECG monitoring in participants identified as higher risk by FIND-AF compared with participants identified as lower risk

    6 months

  • To determine whether detection rates of AF during ECG monitoring are higher amongst participants identified as higher risk of AF, compared with those identified as lower risk

    Rate ratio of AF detection rates during ECG monitoring in participants identified as higher risk by FIND-AF compared with participants identified as lower risk

    5 years

  • To determine whether detection rates of AF during ECG monitoring are higher amongst participants identified as higher risk of AF, compared with those identified as lower risk

    Rate ratio of AF detection rates during ECG monitoring in participants identified as higher risk by FIND-AF compared with participants identified as lower risk

    10 years

Secondary Outcomes (3)

  • To determine, of participants who are detected as having AF during ECG monitoring, the proportion who subsequently receive oral anticoagulation prescription

    6 months

  • To determine, of participants who are detected as having AF during ECG monitoring, the proportion who subsequently receive oral anticoagulation prescription

    5 years

  • To determine, of participants who are detected as having AF during ECG monitoring, the proportion who subsequently receive oral anticoagulation prescription

    10 years

Other Outcomes (16)

  • To determine the AF detection rates amongst participants who are identified as higher risk and lower risk, including in the periods outside of ECG monitoring to determine the incremental yield that is achieved by ECG monitoring over routine care

    6 months

  • To determine how diagnostic yield, C statistic/AUROC, NPV, PPV, sensitivity and specificity, varies at different cut off points of the FIND-AF risk score

    6 months

  • To determine the C statistic/AUROC, NPV, PPV, sensitivity and specificity for alternative approaches to guide systematic AF screening in participants who receive ECG monitoring:

Eligibility Criteria

Age30 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients aged \>30 will be invited to screening in primary care from information present in their electronic health record (EHR) and their FIND-AF score. They will be given Zenicor ECG devices for up to period of 3 week during which they will be asked to record 4 daily ECG recordings. Those patients who are higher risk for AF based on their FIND-AF score, will be reviewed further for multi-modal phenotyping. Patient with new AF detected will be managed by their primary care clinicians.

You may qualify if:

  • Age at enrolment ≥30 years
  • Men with CHA2DS2VASC ≥ 2 and women with a CHA2DS2VASC ≥ 3

You may not qualify if:

  • Known diagnosis of AF
  • On anticoagulation therapy
  • On the palliative care register
  • Unable to give written informed consent for participation in the study
  • Unable to adhere to the study requirements
