Bir devlet hastanesinde 2013-2018 döneminde Acinetobacter enfeksiyonlarında antibiyotik duyarlılığı ve çoğul antibiyotik direnci.

Objective: In this study, it was aimed to investigate the change of antibiotic susceptibility of Acinetobacter baumannii strains over the years and to help develop antibiotic use policy by determining the multiple antibiotic resistance rate. Methods: Acinetobacter species isolated from various clinical samples sent to Necip FazılCity Hospital Microbiology Laboratory between January 2013 and December 2018 were included. Vitek 2 Compact (bioMérieux-SE, France) automated systems were used for the identification and antibiotic susceptibility of the isolates. Results: Acinetobacter isolates were isolated at the most from tracheal aspirate samples (n=73; 35%) and samples sent from Anesthesia and Reanimation intensive care unit(n=160; 68%). The distribution of antibiotic sensitivity percentages (%) was given as yearly, three-year averages for 2013-2015, 2016-2018, and the total average for 2013-2018. In the study period, the highest sensitivity was determined to colistin at 97% and the lowest to ceftriaxone at 5%. When the antibiotic sensitivity rates of A. baumannii are evaluated roughly; In the period of 2016-2018, compared to 2013-2015, there was a decrease in sensitivity to amikacin, ampicillin-sulbactam, cefepime, ceftriaxone, colistin and tigecycline, while sensitivity to other antibiotics was observed. Multiple antibiotic resistance was examined in a total of 237 A. baumannii isolated. Multidrug resistant (MDR) resistance was 92%, Extensively Drug Resistant (XDR) resistance was 84% and Pan Drug Resistant(PDR) resistance was 3%. Conclusion: It is observed that resistance against some antibiotics has increased in A. baumannii over the years, and resistance to some antibiotics has decreased. It seems that our XDR resistance rate is very high. Our PDR resistance rate is higher than that of America, but lower than many European countries. In the other hand our result is lower than the average of Turkey. [ABSTRACT FROM AUTHOR]
