The Hirslanden Group uses two different methods to assess infections. The Hospital Infection Surveillance System (HISS) is used in ICUs, whilst SwissNoso is used on general wards. As the largest database on nosocomial infections in the world, HISS offers the best possible opportunities for comparison. Meanwhile, SwissNoso offers a national benchmark.

Device­associated infections in the intensive care unit includes the number of septic conditions associated with central venous catheters, the number of urinary tract infections in connection with urinary catheters, and the number of cases of pneumonia in connection with mechanical ventilation.

As a result of a change in definition by the German National Reference Center for Surveillance of Nosocomial Infections (NRZ), pneumonia and bronchitis, urinary tract infections and sepsis will be measured with and without devices from 2017. In order to monitor infections, hygiene inspections are made twice a year at all Hirslanden hospitals by the German Consulting Centre for Hospital Epidemiology and Infection Control (BZH) based in Freiburg im Breisgau.
