Development of consensus best treatment plans for new-onset systemic juvenile idiopathic arthritis

Purpose Currently, there is significant variability in the therapeutic approaches to new onset systemic Juvenile Idiopathic Arthritis (sJIA), as evidenced by surveys using case presentations administered to Childhood Arthritis and Rheumatology Research Alliance (CARRA) members. Understanding the comparative effectiveness of these diverse therapeutic approaches would likely result in better health outcomes. We therefore aimed to derive consensus based treatment plans, standardized assessment intervals and data collection plans for clinical use to facilitate comparative effectiveness studies for new-onset sJIA. Eligible patients may be enrolled into any of the treatment plans at the treating physician’s discretion.
