Objective: In recent years, the prevalence of health care-associated infections (HAIs) has increased as a result of the spread of invasive procedures and immunosuppressive therapies. Bloodstream infections (BSIs) are important causes of mortality and morbidity among HAIs and enterococci are among the most common organisms responsible for these infections The most frequent two species are Enterococcus faecium and E. faecalis causing BSIs due to enterococci. The aim of this study was to retrospectively investigate E. faecium and E. faecalis BSIs that developed in various clinics of Samsun Training and Research Hospital between January 2014 and November 2018.
Methods: BSIs developed during the study period were analyzed retrospectively. Enterococcal BSIs were recorded, and comparisons were made. Surveillance data and automation system of our hospital were used for data collection.
Results: A total of 138 enterococcal BSIs were detected during the study period. 76.7% of them were due to E. faecium and they were most frequently detected in the intensive care unit (ICU) patients. Most commonly defined ones among enterococcal BSIs were related to central venous catheters (CVCs). E. faecium BSIs were found to be higher in males in a statistically significant level. The 30-day mortality showed no statistically significant difference between BSIs due to both species. Three E. faecium and four E. faecalis strains were resistant to teicoplanin and vancomycin. Although ampicillin resistance is higher in E. faecium, difference between two species was not statistically significant. Infective endocarditis (IE) was detected in 3 (9.1%) patients in the E. faecium group and 8 (8.3%) patients in E. faecalis group. All patients with IE had CVC-related BSIs.
Conclusions: Increased antibiotic resistance in E. faecalis and E. faecium results in important problems especially in CVC-related BSIs developing in the ICUs. In addition, these infections may be accompanied by IE and patients should be evaluated in detail in this regard.
