WORKING GROUP NAME: PATIENT OUTCOMES IN LONGITUDINAL OBSERVATIONAL STUDIES (POLOS)

We define critical outcomes as those which are important to patients and essential to their well-being. These outcomes can occur throughout the course of the diseases and should be evaluated in prospective longitudinal observational studies (PLOS). The goal of our group is to identify critical long-term outcome domains and sub-domains for long-term studies in patients with rheumatoid arthritis (RA).
