Swissnoso is dedicated to the reduction of nosocomial infections and multi-resistant germs. For the monitoring and prevention of healthcare-associated infections, various modules are available. A key element of the monitoring modules is the regular delivery of module-specific data to Swissnoso.

The purpose of this implementation guide is to specify the exchange format for data transmission within the framework of the Swissnoso CAUTI Surveillance module based on the FHIR® standard from HL7®.

The CAUTI Surveillance module, which has been available to all Swiss acute care hospitals since January 2022, is used to monitor symptomatic CAUTI as well as catheter use as an indicator of the frequency of CAUTI and non-infectious complications of urinary catheterization. Optionally, hospitals may also record the indication for urinary catheterization. Mandated by the Federal Office of Public Health (FOPH), Swissnoso established the module in 2021 based on the pilot program “progress! Safe urinary catheterization” that Patient Safety Switzerland and Swissnoso conducted together from 2015 to 2018.
