The German Electronical Reporting System for Infection Protection (DEMIS) places the highest demands on flexibility int the definition of reports and their content. This is the only way the public health service will be able to respond appropriately and, above all quickly to outbreaks in the future. Through the consistent and coordinated use of HL7 FHIR (Fast Healthcare Interoperability Resources) and CTS2 (Common Terminology Service), the DEMIS pilot study was able to show that it is possible to comprehensively address the requirements with existing approaches.
