The Childhood Arthritis & Rheumatology Research Alliance Consensus Treatment Plans: Towards Comparative Effectiveness in the Pediatric Rheumatic Diseases.

The pediatric rheumatic diseases are a heterogeneous group of rare diseases, posing a number of challenges for the use of traditional clinical and translational research approaches. Innovative comparative effectiveness approaches are needed to efficiently study treatment approaches and disease outcomes. The Childhood Arthritis and Rheumatology Research Alliance (CARRA) developed the consensus treatment plan (CTP) approach as a comparative effectiveness tool for research in pediatric rheumatology. CTPs are treatment strategies, developed by consensus methods among CARRA members, intended to reduce variation in treatment approaches, standardize outcome measurements, and allow for comparison of the effectiveness of different approaches with the goal of improving disease outcomes. To date, CTPs have been published for 7 different diseases and disease manifestations. The approach has been successfully piloted for juvenile localized scleroderma, systemic onset juvenile idiopathic arthritis (JIA), polyarticular JIA, dermatomyositis, and lupus nephritis. Large-scale studies are underway for systemic JIA and polyarticular JIA, with the CARRA patient registry serving as the data collection platform. These studies have been designed with stakeholder involvement, including active input from CARRA providers, patients, and parents, with the goal of increasing the feasibility and ensuring the relevance of the outcomes. These studies include ancillary biospecimen collection intended to support additional translational and mechanistic studies. Data from these ongoing CTP studies will provide more information on the ability of this approach to identify effective treatment strategies and improve outcomes for the pediatric rheumatic diseases.
