Registries in allergy: Structure, target groups, and key findings of allergy-focused registries in Germany

Abstract

In allergology, clinical registries fill knowledge gaps of epidemiology, mechanisms of allergic diseases, and real-world treatment outcomes. Considering the continuous rise of allergic diseases worldwide, registries become increasingly important for the optimization and harmonization of patient care. In the current review, we present four ongoing allergy-focused registries initiated in Germany. We conducted a focused literature search and discussed their structure, main purposes, and findings. Registries included are the "Information Network of Departments of Dermatology", the "European Anaphylaxis Registry", the "GAN Severe Asthma Registry", and "TREATgermany". Despite differences in scope and operation, all registries gather harmonized real-world data that is indispensable for evidence-based decision making in clinical practice and ultimately improves patient care in allergology.
