Baseline Evaluation of Causative Agents and Their Susceptibility Patterns of Late-Onset Blood Stream İnfections İn A Nıcu; Gram-Negative Domination
Öz
Background Blood stream infections (BSI) are the most common hospital-acquired infections in neonatal intensive care units (NICU). Despite the improvement of medical capabilities with neonatal care, diagnosis of BSI in neonates is still problematic. Blood cultures are main confi rmatory tool for neonates with clinical signs and symptoms of BSI. They are also useful for determination of pathogen and their antimicrobial susceptibilities for surveillance purposes. In this retrospective study, we aim to determine the causative bacteria of late-onset neonatal sepsis and their antimicrobial susceptibilities to create a baseline data for active surveillance and empiric antimicrobial regimens.
Materials and Methods: The study was conducted at NICU during three-year period from opening date 2013 to 2015. We retrospectively evaluated the blood cultures of the neonates with the proven diagnosis of late-onset blood stream infection.
Results: Total number of 1245 blood culture samples of 516 neonates with suspected blood stream infection was evaluated during the three-year study period. Among 516 neonate included in the study, 35 of them (6.8%) suffered BSI. Causative agent of BSI was reported in 2.8% (n=35) of all the samples. When the results of the blood cultures were evaluated through the years, we did not determine any signifi cant difference (p>0.05). Gram-negative bacteria caused late-onset neonatal sepsis cases (88.9%) more commonly than gram positive ones (17.1%). K. pneumoniae was identifi ed as the most predominant bacterium (45.7%), followed by E. cloaca (11.4%) and other enteric bacilli. Coagulase negative staphylococci and Enterococcus faecalis were the Gram-positives determined in 17.1% of the cases. Carbapenems for the Gram-negative bacteria and glycopeptides for the Gram-positive bacteria were the most susceptible antimicrobials as expected.
Discussion and Conclusion: The study was conducted at NICU during three-year period from opening date 2013 to 2015. We retrospectively evaluated the blood cultures of the neonates with the proven diagnosis of late-onset blood stream infection.
