SOLO/Flx questionnaire prototype

Atrial Fibrillation Risk Questionnaire

This app reports only a HIGH or LOW risk comment. It does not display a percentage chance, numerical risk estimate, or risk score.

Report format: only questions answered “Yes” are listed, followed by the High/Low comment.
Privacy: calculations occur only in this browser; the app does not transmit or store patient answers.

Questionnaire

The Yes/No wording follows the supplied Word document.

1aHave you been diagnosed with atrial fibrillation?

1bAre you currently in AFib?

1cHave you been treated with medication or ablation for AFib?

2aHave you been told you have high blood pressure?

2bAre you being treated for high blood pressure?

3aHave you been told you have sleep apnea?

3bAre you being treated for sleep apnea?

4Are you currently smoking?

5Are you male?

6aDo you drink 7–14 alcoholic beverages a week?

6bDo you drink 15 or more alcoholic beverages a week?

7Have you been diagnosed as having a myocardial infarction (heart attack)?

8Have you been diagnosed with heart failure or congestive heart disease?

Atrial Fibrillation Risk Questionnaire Report

Positive “Yes” responses

Body mass index

Blood pressure analysis

BMI alone cannot diagnose cachexia, and one blood-pressure reading cannot diagnose hypertension. The classifications are screening comments for clinical review.

Method and sources

The AF calculation remains hidden; the report adds BMI and blood-pressure interpretation.

How the High/Low label is assigned

A “Yes” response indicating prior diagnosis of AF, current AF, or treatment for AF produces a High AF pre-test probability comment.

For people without prior/current/treated AF, the label follows the published HARMS₂‑AF framework: hypertension, age, BMI, male sex, sleep apnea, smoking, and alcohol are combined internally. The published high-risk threshold is used, but the app does not show the score or a percentage.

Positive Yes responses appear in the report. BMI is calculated from entered height and weight; obesity is defined at BMI ≥30 kg/m² for the HARMS₂‑AF framework. The report also describes normal weight, overweight/not obese, and a low-BMI range that may warrant assessment for cachexia. Blood pressure is categorized using standard adult ACC/AHA ranges; a single reading is not treated as a diagnosis. Ethnicity, belt size, and exercise remain in the questionnaire because they were requested, but they are not added to the report unless a validated calculation requires them.
