Electronic Warning System for Atrial Fibrillation

Completed

Phase N/A Results N/A

Trial Description

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.

Outcomes

Type Measure Time Frame Safety Issue
Primary Rate of initiation of adequate measures to prevent stroke (prescription) by physician in charge End of hospital stay (expected average duration of 1 week) No
Secondary Time interval from alert to filling out CHA2DS2VASC Score through alert system by physician in charge During hospital stay (expected average duration of 1 week) No
Secondary Time interval from filling out CHA2DS2VASC Score through alert system to initiation of adequate stroke preventive measures by physician in charge During hospital stay (expected average duration of 1 week) No
Secondary Rate of ignored alerts (no evaluation of CHA2DS2VASC Score and no initiation of adequate measures to prevent stroke (prescription)) by physician in charge End of hospital stay (expected average duration of 1 week) No
Secondary Rate of correct evaluation of the CHA2DS2VASC Score by physician in charge End of hospital stay (expected average duration of 1 week) No
Primary Rate of initiation of adequate measures to prevent stroke (oral anticoagulant prescription) by physician in charge End of hospital stay (expected average duration of 1 week) No
Secondary Use of the CHA2DS2VASc score calculation tool by the physician in charge During hospital stay (expected average duration of 1 week) No
Secondary Rate of correct evaluation of the CHA2DS2VASC Score through the calculation tool by physician in charge End of hospital stay (expected average duration of 1 week) No
