New alert system aims to prevent strokes in half a million heart patients
NCT ID NCT05236556
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a computer alert in doctors' charts can help more atrial fibrillation patients get blood thinners to prevent strokes. About 5,094 patients and their doctors are involved. The alert fires during visits if a patient has high stroke risk but isn't on blood thinners, nudging the doctor to prescribe them.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Best practice advisory (BPA) alert system
- What this could lead to
- If successful, this could increase the number of atrial fibrillation patients who get blood thinners, reducing their stroke risk.
- What could go wrong
- This is a behavioral intervention, not a new drug, so its impact may be modest. The trial is large but relies on doctors following alerts, which may not always happen.

Inclusion Criteria: * Providers caring for patients aged 18 years and older with international classification of disease 10th revision (ICD-10) diagnostic code consistent with atrial fibrillation (AF) or atrial flutter who had a visit with a primary care provider or cardiovascular medicine specialist in the previous one year with the diagnosis of AF present as an active diagnosis in the electronic health record (EHR). * Patients aged 18 years and older with ICD-10 diagnostic code consistent with AF or atrial flutter who had a visit with a primary care provider or cardiovascular medicine specialist in the previous one year with the diagnosis of AF present as an active diagnosis in the EHR. Exclusion Criteria: * Left atrial appendage closure * Hospice status * Providers who do not care for patients aged 18 years and older with ICD-10 diagnostic code consistent with AF or atrial flutter who had a visit with a primary care provider or cardiovascular medicine specialist in the previous one year with the diagnosis of AF present as an active diagnosis in the EHR. * Patients under the age of 18; patients without a ICD-10 diagnostic code consistent with AF or atrial flutter who had a visit with a primary care provider or cardiovascular medicine specialist in the previous one year with the diagnosis of AF present as an active diagnosis in the EHR. Patients will also be excluded from this study if they are known to be pregnant or a prisoner.
