PsA Digital Phenotyping and Inflammation Drivers Study

PsA Digital Phenotyping and Inflammation Drivers Study

The goal of this observational study is to develop and internally validate a machine learning model for detecting flare using a digital biomarker and a machine learning model for predicting flare, in patients with psoriatic arthritis. The main questions it aims to answer are:

• In patients with psoriatic arthritis, is a digital biomarker capable of detecting a flare as compared to clinical defined flare by the rheumatologist?
• In patients with psoriatic arthritis, what factors trigger a psoriatic arthritis flare ?

Participants will be requested to:

• Install app on their phone
• Use a smartwatch
• Complete questionnaires
• Collect biological material

Inclusion Criteria:

• Diagnosed with PsA
• Age 18 years or older and competent
• Using a smartphone
