Clinical Trial Summary

In the RedStroke study, the effect of a smartphone application in detecting Atrial Fibrillation (AF) will be assessed in a double-blind randomised controlled multicenter trial. Outpatients with an elevated risk for atrial fibrillation will be randomized to an intervention arm (app group) and to a standard-of-care arm (control group). Both groups will have the app installed on their private smartphones and will be asked to perform a predefined measurement protocol. All patients will continue their prior therapy with their general practitioner and obtain every medical treatment indicated. This study will not cause any restrictions on the usual treatment of the study patients.

The only difference between the two groups will be, that patients in the app group will be informed by their local PI, if the recordings of the app indicate AF (and obtain a 14 day Holter ECG for AF verification), whereas the patients in the "usual care" group will obtain the read out of the app at the end of the study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Prevalence of Atrial Fibrillation	Prevalence of Atrial Fibrillation confirmed by ECG in the app group compared with the standard care group	6 months
Secondary	Costs related to the AF screening	Health care resource utilization data related to AF diagnosis will be collected for all patients during the study. To evaluate the clinical consequences associated with screening, additional endpoints include the initiation of AF-related therapies including anticoagulants, antiarrhythmic agents or hospitalizations with a primary diagnosis of AF. As a general measure of health care utilization, hospitalization for any cause will also be evaluated.	6 months
Secondary	Compliance of patients using the app	Number of patients who regularly use the app according to study instructions	6 months
