BACKGROUND: Bacteremia is a serious clinical condition that often precedes or accompanies sepsis and septic shock, which remain leading causes of hospital mortality worldwide. Understanding the epidemiology of bacteremia—including antimicrobial resistance patterns—and treatment principles is critical for improving outcomes in patients with chronic critical illness and severe brain injury.
AIM: This study aimed to determine the profile of bacteremia in patients with severe brain injury in predominantly chronic critical illness admitted to intensive care units from 2018 to 2024 and their antibiotic susceptibility; to identify common resistance mechanisms of leading pathogens; and to formulate recommendations for optimizing antimicrobial therapy in this population.
METHODS: The study included patients with severe brain injury in predominantly chronic critical illness who developed clinically significant bacteremia. Microorganisms were identified, and antibiotic susceptibility was determined using the BD Phoenix 100 automated analyzer. Susceptibility interpretation followed EUCAST criteria.
RESULTS: Among 292 patients in predominantly chronic critical illness, the top ten bacteremia pathogens were primarily Gram-negative organisms, including Klebsiella pneumoniae (40.11%), Pseudomonas aeruginosa (6.22%), Proteus/ Providencia spp. (5.94%), Acinetobacter baumannii (5.37%), Serratia marcescens (4.24%), Escherichia coli (3.10%), and Enterobacter cloacae (1.69%). During this period, high carbapenem resistance was observed in Klebsiella pneumoniae (84.29%) and Pseudomonas aeruginosa (61.90%). Among Gram-positive organisms, coagulase-negative staphylococci predominated (21.47%).
CONCLUSION: Gram-negative bacteria with high levels of antibiotic resistance, including carbapenem-resistant Klebsiella pneumoniae and Pseudomonas aeruginosa, were the predominant pathogens in bacteremia among patients with chronic critical illness in intensive care units. Establishing effective empirical antimicrobial therapy protocols requires analysis of local antibiotic susceptibility data.
