Introduction
Many studies of infection prevention measures (ICM) appear proving a reduction of methicillin-resistant Staphylococcus aureus (MRSA) - colonisation or - infection rates. Infection control personal has to decide if ICM should be introduced in their hospital. Here we give an example how an infection prevention potential (IPP) could be calculated for MRSA patients in a 500-bed tertiary care hospital under a given MRSA-screening, contact isolation precaution and active surveillance program.
