The overall goal is to improve outcomes among patients with atrial fibrillation (AF) by preventing stroke. The investigators propose to implement an automated algorithm using electronic medical record (EMR) data to alert physicians in a large primary care practice network at the Massachusetts General Hospital (MGH) of their patients with AF and elevated stroke risk that are not taking an anticoagulant for stroke prevention. The investigators hypothesize that interventions to notify physicians of such individuals may prompt reassessment for the need for anticoagulation, and thereby increase guideline-indicated anticoagulation rates. Additionally, in a survey component, physicians will characterize reasons for not pursuing anticoagulation in AF patients at elevated risk for stroke.
The overall goal is to improve outcomes among patients with atrial fibrillation (AF) by preventing stroke. The investigators propose to implement an automated algorithm using electronic medical record (EMR) data to alert physicians in a large primary care practice network at the Massachusetts General Hospital (MGH) of their patients with AF and elevated stroke risk that are not taking an anticoagulant for stroke prevention. Using a medical record algorithm, there are an estimated 2,000 to 3,000 such patients in the primary care practices at MGH. The investigators hypothesize that interventions to notify physicians of such individuals may prompt reassessment for the need for anticoagulation, and thereby increase guideline-indicated anticoagulation rates.
The investigators define the following three Specific Aims to address the primary study hypothesis:
Specific Aim 1: Implement an automated alerting system within the EMR to notify primary care physicians (PCPs) of patients with AF at elevated stroke risk that are not being treated with anticoagulants. To maximize efficiency of the effort, the alert will not require a concurrent clinic visit, but rather will occur with existing data aggregated from the medical record independent of any clinical encounter.
Specific Aim 2: Test whether the alerting system increases the rate of anticoagulation at 3 months after implementation.
Specific Aim 3: Characterize the reasons for not pursuing anticoagulation in AF patients at elevated risk for stroke.
Specific Aim 4: Assess how PCPs want to be alerted about anticoagulation status in the future and what types of support they find helpful

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Baseline alert | Experimental | For patients randomly selected for the baseline alert arm, their physicians will be alerted via email that a patient(s) under their care has atrial fibrillation, is at high risk of stroke, and is not currently anticoagulated. Physicians will also be asked to complete a survey related to anticoagulation for each patient and will be provided with educational resources and consultation services. |
|
| 3-month alert arm | No Intervention | For patients randomly selected for the 3-month alert arm, their physicians will not be notified during the 3-month study follow-up period. Instead, PCPs will be sent alerts after 3-months via email for these patients. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Baseline alert | Other | PCP notification at baseline that patient has atrial fibrillation, high stroke risk, and is not anticoagulated. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Proportion of patients taking an anticoagulant | Difference in the proportion of patients with AF at high risk of stroke taking an anticoagulant at 3-months in the baseline alert arm , compared to the proportion taking an anticoagulant at 3-months in the 3-month alert arm | 3-months |
| Measure | Description | Time Frame |
|---|---|---|
| Proportion of patients taking direct oral anticoagulants vs. warfarin | Difference in the proportion of patients with AF at high risk of stroke taking an anticoagulant at 3-months in the baseline alert arm , compared to the proportion taking an anticoagulant at 3-months in the 3-month alert arm, stratified by type of anticoagulant (direct oral anticoagulants vs. warfarin) | 3-months |
