20.500.12556/DiRROS-15121 The effects of topical antibiotics on eradication and acquisition of third-generation cephalosporin and carbapenem-resistant Gram-negative bacteria in ICU patients : ǂa ǂpost hoc analysis from a multicentre cluster-randomized trial Objectives: The aim was to quantify the effects of selective digestive tract decontamination (SDD) consisting of a mouth paste and gastro-enteral suspension, selective oropharyngeal decontamination with a mouth paste (SOD) and 1-2% chlorhexidine (CHX) mouthwash on eradication and acquisition of carriage of third-generation cephalosporin-resistant Enterobacterales (3GCR-E) and carbapenem-resistant Gram-negative bacteria (CR-GNB) in Intensive Care Unit (ICU) patients. Methods: This was a nested cohort study within a cluster-randomized cross-over trial in six European countries and 13 ICUs with 8665 patients. Eradication and acquisition during ICU stay of 3GCR-E and CRGNB were investigated separately in the rectum and respiratory tract for the three interventions and compared with standard care (SC) using Cox-regression competing events analyses. Results: Adjusted cause specific hazard ratios (CSHR) for eradication of rectal carriage for SDD were 1.76 (95% CI 1.31-2.36) for 3GCR-E and 3.17 (95% CI 1.60-6.29) for CR-GNB compared with SC. For the respiratory tract, adjusted CSHR for eradication of 3GCR-E were 1.47 (0.98-2.20) for SDD and 1.38 (0.92-2.06) for SOD compared with SC, and for eradication of CR-GNB these were 0.77 (0.41-1.45) for SDD and 0.81 (0.44-1.51) for SOD, compared with SC. Adjusted CSHRs for acquisition of rectal carriage during SDD (compared with SC) were 0.51 (0.40-0.64) for 3GCR-E and of 0.56 (0.40-0.78) for CR-GNB. Adjusted CSHRs for acquiring respiratory tract carriage with 3GCR-E compared with SC were 0.38 (0.28-0.50) for SDD and 0.55 (0.42-0.71) for SOD, and for CR-GNB 0.46 (0.33-0.64) during SDD and 0.60 (0.44-0.81) during SOD, respectively. SOD was not associated with eradication or acquisition of 3GCR-E and CR-GNB in the rectum. Conclusions: Among mechanically ventilated ICU patients, SDD was associated with more eradication and less acquisition of 3GCR-E and CR-GNB in the rectum than SC. SDD and SOD were associated with less acquisition of both 3GCR-E and CR-GNB than SC in the respiratory tract. intensive care units -- analysis -- epidemiology bacterial drug resistance anti-infective agents -- therapeutic use decontamination beta-lactamases Gram-negative bacteria gastrointestinal tract -- microbiology -- drug therapy cohort studies colonization ESBL digestive tract enote intenzivne terapije -- analiza -- epidemiologija bakterijska odpornost na zdravila sredstva proti okužbam -- terapevtska raba dekontaminacija beta-laktamaze Gramnegativne bakterije gastrointestinalni trakt -- mikrobiologija -- terapija z zdravili kohortne študije kolonizacija ESBL prebavni trakt true false true Elsevier Angleški jezik Ni določen © 2019 European Society of Clinical Microbiology and Infectious Disease Neznano 2022-05-27 13:11:36 2022-05-27 13:11:37 2022-08-21 03:35:25 0000-00-00 00:00:00 2020 0 Velika Britanija 0 Sodelavca pri raziskavi iz Slovenije: Viktorija Tomič, Franc Šifrer; Nasl. z nasl. zaslona; Opis vira z dne 15. 1. 2020; str. 485-491 iss. 4 Vol. 26 Apr. 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 579 1469-0691 10.1016/j.cmi.2019.08.001 2048615537 https://www.clinicalmicrobiologyandinfection.com/action/showPdf?pii=S1198-743X%2819%2930440-9 1 https://dirros.openscience.si/Dokument.php?lang=slv&id=19759 Univerzitetna klinika za pljučne bolezni in alergijo Golnik 0 0 0
