Evaluation of Vancomycin Resistant Enterecoccal Infections

Abstract

Objective:In recent years, vancomycin-resistant enterococcus (VRE) infections are among the common nosocomial infection factors, especially in intensive care units (ICU). In our study, it was aimed to evaluate the resistance rates of enterococci, which are isolated as a hospital infection (HI).Materials and Methods:The source and resistance rates of HIs due to enterococci were investigated retrospectively in patients hospitalized in Konya Training and Research Hospital in five years. ICU follow-up forms, National Hospital Infections Surveillance data were taken into consideration in determining these patients. HIs; “Centers for Disease Control and Prevention” was defined according to diagnostic criteria, all samples were evaluated by conventional culture methods.Results:6.24% (177) of the factors in all nosocomial infections (2,835) recorded in our hospital were linked to enterococcal spp. 54.8% (97) of the infections were in ICU and 45.2% (80) were in the services. 57.63% (102) of enterococci reproduced in the urine, 27.11% (48) in the blood, 13.56% (24) in the swab cultures of the wound. VRE was the cause of 7 of the patients who were accepted nosocomial infections due to enterococci. The VRE rate is 0.24% among all (2,835) nosocomial infections and among nosocomial infections due to enterococci; It was found to be 3.4%. All VREs were detected as Enterococcus feacium (100%). The most common risk factors in patients were advanced age, urinary and central venous catheters, acute kidney injury or chronic kidney failure. The use of glycopeptides before VRE infection was 42.85%, and 100% of patients had previously used 3rd generation cephalosporins.Conclusion:The more important the isolation, correct identification and determination of antibiotic susceptibility in the infections caused by enterococci, the more vital it is to monitor the antibiotic susceptibility profiles for these bacteria.
