After an extended development and test phase, a first version of the Momo system (analysis, monitoring, and reporting of microorganisms and antimicrobial resistance patterns) could be transferred into routine use at the infection control department of the Vienna General Hospital. To apply it, data from the microbiology department had to be accessed. Using Momo, the infection control team is able to generate almost any kind of retrospective report on the occurrence of microorganisms and antimicrobial resistance patterns based on the hospital data.
