Using Machine Learning to Delineate Patterns in Patient Journeys


Slowing the progression to psoriatic arthritis among patients with psoriasis is crucial to prevent irreversible joint damages. Besides several risk factors, little is known about the complex patterns of psoriasis progression. We will present how we used longitudinal electronic health records and machine learning to uncover hidden patterns in psoriasis patient journey.
