Number of microbiological samples	T0 number = 1456	T1 number = 1456	T2 number = 1456
MDRO	23 (1.5)	14 (0.96)*	2 (0.13)*
ESBL	12 (0.82)	14 (0.96)	2 (0.13)*
MRSA	4 (0.27)	0 (0)	0 (0)
IRAB	6 (0.41)	0 (0)	0 (0)
Resistant P. aeruginosa	1 (0)	0 (0)	0 (0)

Data are numbers (%). ESBL, extended spectrum β-lactamase producing Gram negative bacilli; IRAB, impipenem resistant Acinetobacter baumannii; MDRO, multidrug-resistant organisms; MRSA, methicillin resistant Staphylococcus aureus. *P = 0.004 versus T0, <0.001 versus T1, <0.001 versus T1, respectively. P >0.2 for all other comparisons.
