All of a hospital’s cases of methicillin-resistant Staphylococcus aureus (MRSA) are recorded in MRSA-KISS, which also calculates relevant reference data. MRSA frequency pro 1000 patient days is calculated. Whether the infection was acquired in-hospital or outside is taken into account. Data used for analysis are usually recorded by every hospital, for example the number of patient-days, so surveillance does not represent an increase in workload. 

Participation is possible for every hospital, independent of interest in participating other KISS components. Data must be recorded for the entire hospital, however. Data collection includes only stationary patients, i.e., no outpatient procedures like dialysis are taken into account. Data are to be summarised once per calendar year (no data for individual patients) and are to be entered in the MRSA data collection form on webKess, where evaluation takes place. The data of all participating hospitals are summarised and made available as reference data.

Hospitals interested in taking part in MRSA-KISS must first download the most recent report from this Web site and collect data according to the CDC diagnosis definitions.

In the sub-component MRSA-REHA, MRSA data are collected analogically to MRSA-KISS from rehabilitation facilities.
