Official title
Using N-of-1 Experiments to Answer Patient Generated Research Questions
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The I-STOP-Afib study will test the comparative effectiveness of using N-of-1 trials vs. symptom surveillance alone to reduce Atrial Fibrillation (AF) episode frequency and severity and improve quality of life for AF patients. The study will involve randomizing almost 500 paroxysmal AF patients to either AF episode tracking versus engaging in testing the relationship between participant-selected triggers and AF episodes utilizing a mobile-app based N-of-1 study design. Both groups will complete a validated survey to assess AF severity, essentially a measure of quality of life while living with AF, before and after a 3 month testing period.
