The importance of colonization pressure in multi-resistant Acinetobacter baumannii acquisition in a Greek intensive care unit
Critical Care, 06/14/2012
Arvaniti K et al. – Acquisition of multi–resistant A. baumannii in intensive care unit (ICU) patients is strongly correlated to colonization pressure. High levels of colonization pressure and more than two carriers per week independently increase acquisition risk. Patient–related factors, such as infection at admission and long hospitalization before ICU, can identify imported A. baumannii carriers. Medical patients with extended administration of antibiotics and long duration of mechanical ventilation in the ICU were the most vulnerable to acquisition.
