This article provides a review of German emergency registries which follow the overall objective of quality improvement in emergency care. The various registry projects are briefly presented and compared with regard to their objectives and specific field of emergency care. The aim is to create a basis for future registry projects with reference to aspects of methodology, data sources, and scope. The results show that none of the projects cover the whole emergency care chain in a comprehensive way, i.e., across the prehospital and clinical sector. This reveals the need for the establishment of a registry that spans over a broader range of the care chain, in order to analyse the patient- or case-based data along the complete emergency care process.
