RA App Overestimates Active Disease

Self-reported joint counts showed modest agreement with physician assessments and tended to overestimate active disease in a community-based study

A study led by Dr. Swamy Venuturupalli of Cedars-Sinai Medical Center assessed a smartphone-based app for joint self-assessment in 100 rheumatoid arthritis patients. It found that while patient-reported joint counts had high positive predictive value for identifying low disease activity, they overestimated joint involvement compared to physician evaluations. The app's ability to detect active disease was limited. The modest agreement between patients and physicians highlights challenges in distinguishing pain from tenderness and reflects real-world complexities in patient care.
