Observational Study of Pediatric Rheumatic and Immunologic Diseases in China: The CAPRID Registry

Pediatric rheumatic and immunologic diseases severely impact the health of children and adolescents. Chinese Alliance of Pediatric Rheumatic & Immunologic Diseases (CAPRID) was founded in 2022 to form a national collaboration for high-quality data-driven multi-center pediatric rheumatology and immunology research in China. The CAPRID Registry is an observational, multi-center, longitudinal registry for Chinese pediatric patients with rheumatic and immunologic diseases to explore the clinical phenotypes, diagnoses, complications, real-world drug safety, therapeutic efficacy, adverse events, critical illness and outcomes of Chinese pediatric patients with rheumatic and immunologic diseases.

Hospital-based databases are established and standardized with Observational Medical Outcomes Partnership (OMOP) Common Data Model (CDM) for routine data collection. A web-based registry website is established with standardized electronic case report forms to register patients from CAPRID centers. A mobile application is created to allow long-term follow up and patient-reported outcome collection. The data captured in this registry reflects a "real world" situation with no intervention done outside the routine clinical practice. Treatment plans are determined by the investigator.
