Figure 2: Comparison of median length of stay (LOS) in (A) intensive care unit (ICU), (B) general ward prior to ICU, and (C) general ward after discharge from ICU, in ventilated patients with single cultures of Acinetobacter baumannii alone and those with entirely negative respiratory cultures. NEG= negative cultures (n=95); TOTAL= all A. baumannii cases (n=43); A= cases resistant to β-lactam/-lactamase antibiotics (n=27); B= resistant to aminoglycosides (n=22); C= resistant to 3rd generation cephalosporins (n=13); D= resistant to cefepime (n=22); E= resistant to carbopenams (n=19). Bar = median; * = p<0.05; ** = p<0.01; *** = p<0.001.
