Classifying Self-Reported Rheumatoid Arthritis Flares Using Daily Patient-Generated Data From a Smartphone App: Exploratory Analysis Applying Machine Learning Approaches

Classifying Self-Reported Rheumatoid Arthritis Flares Using Daily Patient-Generated Data From a Smartphone App: Exploratory Analysis Applying Machine Learning Approaches

We treated each weekly flare report as a binary outcome. It was left up to the patient to decide what was classified as a flare. Weeks with an unanswered (missing) flare question are not included in this analysis. To fit a binary classification model, it was necessary to extract a “feature vector” or list of predictors from the sequence of daily symptom data that were mapped to each weekly flare report. The 7 days up to and including each flare report were treated as the exposure period.

Living With Inflammatory Bowel Disease: Protocol for a Longitudinal Study of Factors Associated With Symptom Exacerbations

Living With Inflammatory Bowel Disease: Protocol for a Longitudinal Study of Factors Associated With Symptom Exacerbations

There has been little research exploring the causes of the development or worsening of IBD-related symptoms and what exactly it means when a patient reports a “flare.” Persons with IBD often attribute symptom exacerbation to changes in diet and stress, although there is currently little understanding of which dietary or psychological factors play a role.
