“…5 At the time of admission into the ICU, a higher Acute Physiology and Chronic Health Evaluation II or Sequential Organ Failure Assessment score, clinical presentation with septic shock or severe sepsis, multiple comorbidities (>2), and receiving inadequate antimicrobial therapy in the first 48 hours are all generally considered to be the predictors of mortality after BSI that occur in medical or ICU wards. [6][7][8][9] Bacterial resistance to many antimicrobial classes, which is often encountered in the ICU environment, is nowadays a major concern for the clinician because it might be associated with increased length of hospital stay, worse outcomes, and difficulty of treatment. 10,11 In particular, according to a recent consensus statement issued by an international panel of experts, a multidrug-resistant (MDR) pattern can be defined as nonsusceptibility to at least 1 agent in !3 antimicrobial categories, whereas an extremely drugresistant pattern is defined as nonsusceptibility to at least 1 agent in all but 2 antimicrobial categories.…”
