Evaluation of patients who were followed with bacteremia in intensive care unit

Abstract

Purpose: In this study, the microorganisms isolated from the blood cultures of the patients who are hospitalized in the general intensive care unit (ICU) of our hospital were evaluated retrospectively and it was aimed to obtain the guiding data for the appropriate empirical treatment selection. Materials and Methods: Species distribution and antimicrobial susceptibility of 163 microorganisms, isolated from blood cultures of 152 inpatients aged 18 years and older were evaluated retrospectively. Blood cultures were taken during the febrile period of inpatients who stayed in clinic were incubated in blood culture media in BACTEC automated blood culture system. Results: Of these microorganisms found, 68\% (n=111) were Gram positive bacteria, 25\% (n=40) were Gram negative bacteria, and 7\% (n=12) were fungi. The most common microorganisms were coagulase negative staphylococcus (CoNS), Escherichia coli and Candida spp. Of the Gram negative agents isolated from blood cultures, 7\% (n=12) were Escherichia coli, 6\% (n=9) were Klebsiella spp., 5\% (n=8) were Pseudomonas spp., 4\% (n=6) were Acinetobacter spp. Extended Spectrum Beta Lactamase (ESBL) was detected 75\% (n=9) of E.coli, and 78\% (n=6) of Klebsiella spp. isolate. Conclusion: Epidemiological information about species distribution and antibiotic resistance of the isolated infectious agents and will contribute to the determination of their antibiotic usage and to decrease the morbidity and mortality rates.
