Background: Recent Japanese epidemiology of neonatal sepsis and its predominant pathogens has not been reported. It is also unknown whether there are center differences in the incidence of neonatal sepsis, including early-onset sepsis (EOS) and late-onset sepsis (LOS) in Japan. Objectives: To investigate the morbidity and characteristics of neonatal sepsis in recent years and the differences in the incidence of sepsis among Japanese neonatal care units. Methods: We retrospectively collected the data of newborn infants with culture-proven sepsis that occurred in five Japanese centers of perinatal care from 2006 to 2008. The incidence of sepsis was calculated, including EOS and LOS, and compared among centers. Results: Morbidity from sepsis occurred in 51/6,894 (0.74%) infants. The incidence of EOS and LOS was 0.13 and 0.61%, respectively. The incidence of total sepsis and LOS in infants <1,000 g of birth weight was significantly higher than that in infants who weighed >1,000 g at birth, whereas there were no significant differences in the incidence of EOS between the different birth weights. Methicillin-resistant Staphylococcus aureus was the most common pathogen involved in morbidity and mortality of neonatal sepsis. Significant center differences were observed in the incidence of LOS, but not EOS. Conclusions: The majority of culture-proven neonatal sepsis is LOS, which differs among centers, especially in infants who weigh <1,000 g at birth in Japan. We consider that it is important to control nosocomial infection in newborn care units to further reduce the morbidity of neonatal sepsis in Japan.
