Distribution of chlorhexidine and octenidine MIC for all ICU-attributable bacterial isolates from clinical samples with Staphylococcus aureus (A), coagulase-negative staphylococci (B), Escherichia coli (C), Klebsiella spp. (D) and Pseudomonas aeruginosa (E). MIC were reported as estimated minimal inhibitory concentrations (est. MIC) in [μg/ml] derived from the respective extraction solutions. ICU-attributable bacterial isolates from clinical samples were collected prior to (baseline, light grey bars) and at the end of the intervention period (dark grey bars) applying 2%-chlorhexidine impregnated cloths (chlorhexidine group), 0.08% octenidine wash mitts (octenidine group) or water and soap (routine care = control).
