Abstract:

Sepsis in the neonatal intensive care unit (NICU) remains one of the most significant causes of morbidity and mortality. Multidrug resistant organisms (MDRO) are emerging as important pathogens causing neonatal sepsis in the NICU. Episodes of blood culture-proven sepsis for patients (0 to 90 days) in the NICU at our institution from Jan 2012 through Dec 2015 were retrospectively reviewed. 68 episodes of sepsis (ages 0-54 d, median 7 d; 34 female; 81% premature) were caused by gram-negative bacteria (n=42; 62%), gram-positive bacteria (n=21; 31%), or Candida species (n=5; 7%). The most common organisms isolated were Acinetobacter baumannii (27%), Klebsiella pneumoniae (22%), coagulase-negative Staphylococcus (CoNS) (18%), group B Streptococcus (10%) and E. coli (6%). Compared to non-MDRO cases (n=15; 29%, excluding CoNS and Candida), MDRO (n=36; 71%) were associated with higher mortality (58% vs. 13%, p=0.005) and more delay in providing targeted antimicrobial therapy (61% vs. 13%, p=0.004). Sepsis due to the most resistant organisms (A. baumannii and K. pneumoniae Carbapenemase (KPC)-producing bacteria, n=20; 39%) was associated with higher mortality, higher rates of leukopenia and thrombocytopenia (p=0.001, 0.02, 0.04; respectively), and significantly associated with exposure to a carbapenem and vancomycin before onset of sepsis (cases exposed=16/20; 80%, p<0.001, median days of exposure=10 (3-17)). MDRO are the most common causative pathogens of sepsis at our NICU, and are associated with higher mortality compared to non-MDRO. Previous exposure to a carbapenem and vancomycin was associated with sepsis caused by the most resistant organisms.
