Background:Pseudomonas aeruginosa, is the third etiologic agent of healthcare associated infections, and the most frequent pathogen in ventilator-associated pneumonia (VAP). In critical care units is associated with high mortality, long hospital stay, and high healthcare-associated costs. We evaluated the effectiveness of filter placement in the water taps in critical care units to prevent the occurrence of healthcare-associated infections (HAIa) by Pseudomonas aeruginosa. Methods: This experimental study was both cross-over and open-label in nature. We included patients admitted for >24 hours in critical care units over 24 months. The study was divided into 4 periods of 6 months each. We divided the study into 2 groups: patients in units with filters and patients in units without filters. We compared the incidence density of P. aeruginosa HAIs (number of cases divided by the number of person days) according the ECDC definition of case criteria between the groups. The 2 test was used, and the magnitude of the association was calculated as a rate ratio with a 95% confidence interval, adjusted using a Poisson regression model. Results: Overall, 1,132 patients were included in the study: 595 in units with water tap filters and 537 in units without water tap filters. HAI incidence among patients in units with water tap filters was 5.3 per 1,000 person days stay; without water tap filters, HAI incidence was 4.7 per 1,000 person days stay (HR, 0.94; 95% CI, 0.47–1.90). Conclusions: The preliminary results of this study indicate a a lower incidence of P. aeruginosa HAIs in units with filters placed in water taps than in units without filters.Disclosures: NoneFunding: None

Abstract Background Multidrug-resistant Enterobacteriaceae (Ent) and Pseudomonas aeruginosa (Pae) are involved in a considerable number of healthcare-associated infections, thus representing a therapeutic challenge. Ceftolozane–tazobactam (C/T) is a combination of a novel cephalosporin with a known β-lactamase inhibitor. Ceftolozane has high affinity for penicillin-binding proteins, improved outer membrane permeability, increased stability against efflux and enhanced stability against chromosomal AmpC β-lactamases compared with other β-lactam antibiotics. This agent is not active against carbapenemases. We evaluated the in vitro activity of C/T against clinical isolates of Ent and Pae collected from 2016- 2017 and compared it to the activity of broad-spectrum antimicrobial agents. Methods 1.644 Ent and Pae non-duplicate clinical isolates were collected in 13 medical centers located in 12 Colombian cities. Minimum inhibitory concentrations (MIC) were performed by broth microdilution and interpreted according to current CLSI guidelines. Isolates tested included 813 Escherichia coli (Eco), 441 Klebsiella pneumoniae (Kpn), 82 Enterobacter spp., (Enb); 60 Serratia marcescens (Sma) and 248 Pae. Comparator agents were ceftriaxone (CRO), cefotaxime (CTX), ceftazidime (CAZ), cefepime (FEP), piperacillin/tazobactam (TZP), ertapenem (ETP), imipenem (IMI), meropenem (MEM). Results Susceptibilities to C/T and comparators of 4 Ent species and Pae are shown in Table 1. Compared with other β-lactams such as CRO, CAZ, TZP, and FEP, C/T had considerably higher susceptibility rates against ESBL, non-carbapenem-resistant (CR) Eco and Kpn isolates. C/T MIC50/90 were: Eco (≤1/≤1); Kpn (≤1/128); Enb (≤1/64); Sma (≤1/≥256); Pae (≤1/≥256). In the case of P.aeruginosa despite the high resistance rates observed in the study, C/T had the best susceptibility, even higher than the carbapenems. Conclusion Overall, C/T demonstrated higher in vitro activity than currently available cephalosporins and TZP when tested against Ent and Pae. C/T provides an important treatment option against infections caused by non-carbapenemase producing Gram-negative pathogens. Further studies are warranted to identify an emerging mechanism of resistance in Colombia. Disclosures All authors: No reported disclosures.

Abstract Background Pseudomonas aeruginosa has recently shown to be one of the most important strains of bacteria and alert pathogens in Europe among Intensive Care Unit patients that provide serious therapeutic problems because of its multidrug resistance. Methods The purpose of this microbiological study was data analysis of device associated- healthcare associated infections (DA-HAIs) in an ICU in terms of the incidents of P.aeruginosa strain infections and its susceptibility within an 8.5-year observation. Results Among 919 isolated strains responsible for 799 DA-HAIs (17,62 ± 1,98/1000 patient-days) in 4010 ICU patients P.aeruginosa was the pathogen in 108/799 (13.52%) cases. Incidence rate (density) of: VAP/1000 MV- days, UTI /1000 UC- days and CLA-BSI/1000 CL- days were 11,15 ± 2.5, 6.82 ± 0.81, 2.35 ± 1.54.respectivelly. P.aeruginosa was the pathogen most frequently responsible for VAP 69/108 (63.88%). Mean frequency of VAP, UTI and CLA-BSI with P.aeruginosa etiology was 69/493 (14.28%), 32/299 (11.1%) and 7/127 (5.77%) respectively. The mean density of P.aeruginosa infection amounted to 2.43/1000 patient-days. The decrease was observed in the total number of DA-HAIs caused by the P.aeruginosa from 15.75% and 3.23/1000 patient-days in 2011 to 5.0% and 1.17/1000 in 2016 (p = 0.0104, p = 0.0348). Starting from 2016 to 2019 incidence and density of P.aeruginosa DA-HAIs increased to 12.33% and 2.63/1000 (p = 0.1388, p = 0.0818). P.aeruginosa was susceptible to ceftazidime, cefepime, amikacin, meropenem, ciprofloxacin, colistin, in 55.55, 58.33, 70.37, 53.73, 50, and 100% respectively. MDR characterised it in 40% in 2011 and 66.7% in 2019, (p = 0.177). Conclusions The study revealed a changeable prevalence of P. aeruginosa strain infections; however their frequency was never highest in our ICU patients as it presented in the last years in Europe. The study showed a significant decrease in 2016 and increase in 2019, a nearly 3-fold increase of P.aeruginosa infections among Gram-negative strain infections, and a 2-fold increase of the P.aeruginosa DA-HAIs frequency between 2016 and 2019 as well as an increased resistance. Microbiological analysis of DA-HAIs in each hospital should be a standard method used in hospital infection control and antibiotic policy. In the case of P.aeruginosa, in order to minimize transmission, preventive infection methods should be assessed mainly in case of VAP.

Epidemiological Characteristics

SUMMARY INTRODUCTION Healthcare associated infections (HAI) are the most frequent complication of hospitalized patients. The aim of this study was to describe the clinical and epidemiological characteristics of critically ill post-surgical patients with a diagnosis of healthcare associated infections, after a pattern of sedoanalgesia of at least 4 days. METHODS All patients over 18 years of age with a unit admission of more than 4 days were consecutively selected. The study population was the one affected by surgical pathology where sedation was based as analgesic the opioid remifentanil for at least 96 hours in continuous perfusion. Patients who died during admission to the unit and those with combined analgesia (peripheral or neuroaxial blocks) were excluded. Data analysis was performed using the statistical package Stata version 7.0. RESULTS The patients admitted to the Post-Surgical Critical Care Unit (PCU) during study were 1789 and the population eligible was comprised of 102 patients. 56.86% of patients suffered IACS. The most frequent IACS was pneumonia associated with mechanical ventilation (30.96 per 1000 days of mechanical ventilation), Pseudomonas aeruginosa being the most frequently isolated germ. The germs with the greatest involvement in multiple drug resistance (MDROs) were enterobacteria, mainly Klebsiella pneumoniae resistant to extended-spectrum beta-lactamases (ESBL). CONCLUSIONS Pneumonia associated with mechanical ventilation is the most prevalent HAI and Pseudomonas aeruginosa is the main etiological agent. The groups of antibiotics most frequently used were cephalosporin and aminoglycosides. It is necessary to implement the prevention strategies of the different HAI, since most of them are avoidable.
