[Quality management in regional anesthesia using the example of a Regional Anesthesia Surveillance System (RASS)].

Regional anesthesia and regional analgesia techniques with or without a continuous catheter are frequently utilized in all areas of modern anesthesiology. There are individual and economic benefits but also risks involved with those techniques. While the incidence of severe complications is rare and preventive action not always possible, the consequences can be detrimental especially with hematoma or abscess formation associated with central neuraxial blocks. Therefore, it is important to create national and international databases with large case numbers utilizing standardized definitions of complications in order to allow realistic risk assessment and early discovery of potential dangers and preventive actions. This article shows the integration of standardized codes from the Regional Anesthesia Surveillance System with a software tool to allow high-quality data acquisition and the building of a foundation for national and international data collection and analysis as well as for feedback of institutional data for individual process optimization as part of a quality management system.
