With the diagnosis and treatment optimization board, the Society for Pediatric and Adolescent Rheumatology (GKJR) has developed a new format for expert-based discussion of rare and complex diseases. So far, 32 cases, predominantly from the areas of hyperinflammation, systemic lupus erythematosus, myositis and nonbacterial osteomyelitis, could be discussed in 8 conferences. The digital format enabled a high number of participants and the involvement of national and international experts.
