Electronic Warning System for Atrial Fibrillation

Not Applicable

Completed

• Conditions: Atrial Fibrillation
• Interventions: Other: Electronic warning alert

• Registration Number: NCT02455102
• Lead Sponsor: Insel Gruppe AG, University Hospital Bern

Brief Summary

The aim of this randomized controlled study is to evaluate whether a newly designed electronic warning system will increase the initiation rate of adequate stroke preventive measures in patients with atrial fibrillation.

Detailed Description

A large proportion of patients with atrial fibrillation do not receive stroke prevention therapy in line with the guidelines, in spite of the presence of an increased risk of stroke. It will be investigated whether an electronic alert to physicians, whose patients with atrial fibrillation do not receive stroke preventive measures, will increase the rate of adequate stroke preventive measures as compared to a control group of patients without an electronic alert. The electronic alerts will be sent if patients with atrial fibrillation but without adequate stroke preventive measures receive in-patient treatment at the University Hospital Bern. The electronic alert system includes a feature that helps the physicians in charge to evaluate the CHA2DS2VASC Score. At the end of the hospital stay medical discharge letters will be reviewed for initiation of adequate stroke preventive measures.
