Incidence of Atrial Fibrillation in Adults Aged ≥ 65AF-StrokeNCT03004859
Opportunistic Screening in Pharmacies for Atrial Fibrillation in Seniors (>65 Years)
An observational study of Incidence of Atrial Fibrillation in Adults Aged ≥ 65, run by RWTH Aachen University at 1 site in Germany.
Trial summary
Atrial fibrillation (AF) is the most common arrhythmia in Germany and is associated with an increased risk of thromboembolic stroke. The risk to suffer from AF increases with age. Early detection of AF and anticoagulation seem the most effective way of preventing ischaemic stroke in patients at risk. Read more about this study

About this study
Official title: Eine Beobachtungsstudie Zur Erfassung Von (Asymptomatischem)Vorhofflimmern Mittels Eines Gelegenheitsscreenings älteren Menschen ab 65 Jahren
Atrial fibrillation (AF) is the most common arrhythmia in Germany and is associated with an increased risk of thromboembolic stroke. The risk to suffer from AF increases with age. Early detection of AF and anticoagulation seem the most effective way of preventing ischaemic stroke in patients at risk. The guidelines of the European Society of Cardiology recommend opportunistic screening for AF by pulse check at each general practitioner visit for all patients aged 65 years or older.
The objective of this study was to test whether an opportunistic AF screening with a hand-held diagnostic tool in a German pharmacy setting is useful in detecting unknown AF among people in the age of 65 and older. Besides a pulse palpation with a hand-held ECG-stick the screening in the pharmacies also includes a questionnaire related to demographics and medical history of the subject as well as several questions concerning the stroke risk stratification (CHA₂DS₂-VASc). Every subject with a positive test result (indication on AF) is insistently asked to make an appointment with his or her general practitioner. The subject receives an information letter for his or her general practitioner that adverts to the positive screening result and the necessity of further diagnostic Investigation.
In order to assess the incidence of unknown AF as well as accomplish the secondary objectives of this study, two follow-ups by means of telephone interviews are performed. First, all subjects with a positive test result are called 8 weeks after the screening in the pharmacies was conducted. The subject is asked several questions concerning personal data/demographics, the stroke risk (CHA₂DS₂-VASc), the medical history regarding to dyspnea and stroke, the bleeding risk (HAS-Bled), the medication, the device, diagnostic, the therapy, the Intervention and the mace. 12 months after the screening in the pharmacies was performed, all participating subjects were called. The list of questions is similar to the one that is used during the first telephone interviews after eight weeks.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Adults ≥ 65 with a positive test result | Adults ≥ 65 that are got a positive test result were asked to visit their general practitioner and are called for an interview two times, 8 weeks and 12 months after the screening in the pharmacy. The results of the data collection and screening in the pharmacies as well as of the two telephone interviews are compared to the results of the adults ≥ 65 with a negative test result. | |
| Adults ≥ 65 with a negative test result | Adults ≥ 65 that are got a negative test result are called for an interview 12 months after the screening in the pharmacy. The results of the data collection and screening in the pharmacy as well as of the telephone interview are compared to the results of the adults ≥ 65 with a positive test result. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of newly detected atrial fibrillation in adults from the age of 65 by means of an opportunistic screening with an ECG hand-held diagnostic tool in a pharmacy setting
The data is going to be collected in a screening period of two weeks in an urban pharmacy setting and a screening period of two weeks of data collection in a more rural pharmacy setting
Measured: 12 months
Secondary outcomes (2)
The subject's behavior change regarding diagnosis and therapy from the ECG measurement at pharmacy at 8 weeks and 12 months.
The subject's behavior change is measured by means of a questionnaire, compiled by the research team. The questionnaire is used during the telephone interviews 8 eight weeks and 12 months. The questionnaire includes questions related to personal data/demographics, the stroke risk (CHA₂DS₂-VASc), the medical history regarding to dyspnea and stroke, the bleeding risk (HAS-Bled), the medication, the device, diagnostic, the therapy, the Intervention and the mace.
Measured: 8 weeks and 12 Months
Identification and description of new therapeutic measures.
Measured: 12 Months

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Atrial fibrillation (AF) is the most common arrhythmia in Germany and is associated with an increased risk of thromboembolic stroke. The risk to suffer from AF increases with age. Early detection of AF and anticoagulation seem the most effective way of preventing ischaemic stroke in patients at risk. The guidelines of the European Society of Cardiology recommend opportunistic screening for AF by pulse check at each general practitioner visit for all patients aged 65 years or older.
The objective of this study was to test whether an opportunistic AF screening with a hand-held diagnostic tool in a German pharmacy setting is useful in detecting unknown AF among people in the age of 65 and older. Besides a pulse palpation with a hand-held ECG-stick the screening in the pharmacies also includes a questionnaire related to demographics and medical history of the subject as well as several questions concerning the stroke risk stratification (CHA₂DS₂-VASc). Every subject with a positive test result (indication on AF) is insistently asked to make an appointment with his or her general practitioner. The subject receives an information letter for his or her general practitioner that adverts to the positive screening result and the necessity of further diagnostic Investigation.
In order to assess the incidence of unknown AF as well as accomplish the secondary objectives of this study, two follow-ups by means of telephone interviews are performed.

Questions about this trial
What is this clinical trial studying?
An observational study of Incidence of Atrial Fibrillation in Adults Aged ≥ 65, run by RWTH Aachen University at 1 site in Germany.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 11 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of newly detected atrial fibrillation in adults from the age of 65 by means of an opportunistic screening with an ECG hand-held diagnostic tool in a pharmacy setting (time frame: 12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03004859, which also lists 18 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Mar 2020; AzTrials last refreshed its copy on 7 Nov 2026.
