VAP due to multidrug-resistant (MDR) bacteria is a frequent infection among patients in ICUs.Patient characteristics and mortality in mono- and polybacterial cases of VAP may differ.A single-centre, retrospective 3-year study was conducted in the four ICUs of a Lithuanian referral university hospital, Radiator aiming to compare both the clinical features and the 60-day ICU all-cause mortality of monobacterial and polybacterial MDR Klebsiella spp.VAP episodes.Of the 86 MDR Klebsiella spp.
VAP episodes analyzed, 50 (58.1%) were polybacterial.The 60-day mortality was higher (p Klebsiella Iced Tea Spoons spp.(46.4 vs.
17.6%).The ICU mortality (44.0 vs.22.
5%) was also higher in the polybacterial episodes.The monobacterial MDR Klebsiella spp.VAP was associated (p p Klebsiella spp.VAP had distinct demographic and clinical characteristics compared to monobacterial, and was associated with poorer outcomes.
