Background/Aim. Ventilator-associated pneumonia (VAP) incidence, causative pathogens, and resistance patterns are different among countries and intensive care units (ICUs). In Europe, resistant organisms have progressively increased in the last decade. However, there is a lack of data from Serbian ICUs. The aims of this study were to evaluate etiology and antimicrobial resistance for pathogens causing VAP in ICU patients, to examine whether there were differences among pathogens in early-onset and late-onset VAP and to identify mortality in patients with VAP after 30 and 60 days of hospitalization. Methods. A retrospective cohort study was conducted in the respiratory ICU and all adult patients diagnosed with VAP from 2009 to 2014 were included. Results. Gram negative organisms were the major pathogens (80.3%). The most commonly isolated was Acinetobacter spp (59.8%). There was a statistically significant increase in the incidence of infection with Klebsiella pneumoniae (8.9% vs 25.6%; p = 0.019). Extensively drugresistant strains (XDR) were the most common (78.7%). Lateonset VAP was developed in 81.1% of patients without differences among pathogens in comparison with early-onset VAP. Acinetobacter spp was susceptible to tigecycline and colistin with a significant increase in resistance to ampicillin/sulbactam (30.2% vs 58.6%; p = 0.01). Resistance rate of Pseudomonas aeruginosa and Klebsiella pneumoniae to carbapenems was 38% and 11%, respectively. In methicillin-resistant Staphylococcus aureus no resistance was observed against vancomycin and linezolid. There was no difference in mortality rate between patients with earlyonset and late-onset VAP after 30 and 60 days of hospitalization. Conclusion. Gram negative organisms were the primary cause of bacterial VAP of which the most common was the XDR strain of Acinetobacter spp. Patients with early- and late-onset VAP had the same pathogens. There was no difference in mortality between this two group of patients during 60 days of hospitalization.

• Background Ventilator-associated pneumonia accounts for 47% of infections in patients in intensive care units. Adherence to the best nursing practices recommended in the 2003 guidelines for the prevention of ventilator-associated pneumonia from the Centers for Disease Control and Prevention should reduce the risk of ventilator-associated pneumonia. • Objective To evaluate the extent to which nurses working in intensive care units implement best practices when managing adult patients receiving mechanical ventilation. • Methods Nurses attending education seminars in the United States completed a 29-item questionnaire about the type and frequency of care provided. • Results Twelve hundred nurses completed the questionnaire. Most (82%) reported compliance with hand-washing guidelines, 75% reported wearing gloves, half reported elevating the head of the bed, a third reported performing subglottic suctioning, and half reported having an oral care protocol in their hospital. Nurses in hospitals with an oral care protocol reported better compliance with hand washing and maintaining head-of-bed elevation, were more likely to regularly provide oral care, and were more familiar with rates of ventilator-associated pneumonia and the organisms involved than were nurses working in hospitals without such protocols. • Conclusions The guidelines for the prevention of ventilator-associated pneumonia from the Centers for Disease Control and Prevention are not consistently or uniformly implemented. Practices of nurses employed in hospitals with oral care protocols are more often congruent with the guidelines than are practices of nurses employed in hospitals without such protocols. Significant reductions in rates of ventilator-associated pneumonia may be achieved by broader implementation of oral care protocols.

Objective.Surveillance for ventilator-associated pneumonia (VAP) using standard Centers for Disease Control and Prevention (CDC) criteria is labor intensive and involves many subjective assessments. We sought to improve the efficiency and objectivity of VAP surveillance by adapting the CDC criteria to make them amenable to evaluation with electronic data.Design.Prospective comparison of the accuracy of VAP surveillance by use of an algorithm with responses to prospective queries made to intensive care physicians. CDC criteria for VAP were used as a reference standard to evaluate the algorithm and clinicians' reports.Setting.Three surgical intensive care units and 2 medical intensive care units at an academic hospital.Methods.A total of 459 consecutive patients who received mechanical ventilation for a total of 2,540 days underwent surveillance by both methods during consecutive 3-month periods. Electronic surveillance criteria were chosen to mirror the CDC definition. Quantitative thresholds were substituted for qualitative criteria. Purely subjective criteria were eliminated. Increases in ventilator-control settings were taken to indicate worsening oxygenation. Semiquantitative Gram stain of pulmonary secretion samples was used to assess whether there was sputum purulence.Results.The algorithm applied to electronic data detected 20 patients with possible VAP. All cases of VAP were confirmed in accordance with standard CDC criteria (100% positive predictive value). Prospective survey of clinicians detected 33 patients with possible VAP. Seventeen of the 33 possible cases were confirmed (52% positive predictive value). Overall, 21 cases of confirmed VAP were identified by either method. The algorithm identified 20 (95%) of 21 known cases, whereas the survey of clinicians identified 17 (81%) of 21 cases.Conclusions.Surveillance for VAP using electronic data is feasible and has high positive predictive value for cases that meet CDC criteria. Further validation of this method is warranted.
