For this analysis invasive isolates (blood and cerebrospinal fluid) tested against the corresponding antibiotic (category) were considered only. If multiple antibiotics within the same antibiotic category were tested, the most resistant result was selected. In case of multiple isolates, the first isolate per patient, microorganism and calendar year was included only. Results are reported as delivered by laboratories. Isolates are linked to the regions via hospital identifiers. Since isolates that are not assigned to a hospital covered by ANRESIS (‘NA’) are also taken into account when calculating the nationwide N, it is possible that the nationwide N is greater than the sum of the individual regions. The following extrapolation procedure was used to calculate incidences:  Each hospital was classified as covered or not covered in the ANRESIS database in each year. Using this data, a coverage rate based on hospital patient days was calculated for each linguistic region (Latin vs. German-speaking) and hospital type (university vs. non-university) and year. These coverage rates were then applied to count data obtained from the hospitals participating in ANRESIS to obtain a national count. The population data used in the denominator was obtained from the Swiss Federal Statistical Office. Statistics may be influenced by the changing number of laboratories participating.
