About this study

This retrospective and prospective study is to investigate the incidence of Carbapenemase-producing bacteria (CPB) at the University Hospital Basel, the time to detection of CPB and to initiation of infection control measures, the risk factors associated with carriage of CPB, type and duration of previously administrated antibiotic medication, antibiotic treatment, as well as to assess the outcomes of the affected patients.

Being tested
data collection for demographic data, data collection for clinical data, data collection for treatment data, data collection for microbiological data
Keywords
Carbapenemase-producing Klebsiella pneumoniae, antibiotic resistancy, infections with Carbapenemase-producing Bacteria (CPB), Carbapenemase-producing Bacteria
