Relocation of KPC-positive patients among different hospital wards. Relocation has been analyzed in the two periods of time: Jan 2009-Jun 2010 and Jul 2010-Dec 2011. Percentage of MDR isolates (including KPC-positive strains) were calculated on the total number of KPC-positive patients (29 and 160 for the first and second period of analysis, respectively). The first number describes MDR percentages of patients that newly acquired MDR organisms in the indicated hospital units; the second number refers to the absolute number of patients. The third bracketed number describes the percentage of patients found with MDR isolates (both newly and previously acquired) over the total number of KPC-positive patients hospitalized in the indicated ward. Abbreviations are: ICU = Intensive Care Unit; MU = Medical Unit; SU = Surgical Unit; LTCU = Long Term Care Unit; MDR = multi-drug-resistance.
