Changes in incidence and etiology of early-onset neonatal infections 1997-2017 - a retrospective cohort study in western Sweden.

ABSTRACT: BACKGROUND:The objective of the study was to evaluate data on early-onset neonatal invasive infections in western Sweden for the period 1997-2017. To identify changes in incidence, etiology and mortality and compare to previous studies from the same area starting from 1975. METHODS:Observational epidemiological, retrospective study on infants 0-6?days of age with a positive culture in blood and/or cerebrospinal fluid between 1997 and 2017. A comparison was made of the incidence between 2008 and 2017 compared to 1997-2007. Changes in the incidence of infections due to Group B streptococci, Staphylococcus aureus and aerobic Gram-negative rods were assessed from 1975. RESULTS:The total incidence, including both recognized pathogens and commensals as causative agents, was 1.1/1000 live births. The incidence declined from 1.4/1000 LB in 1997-2007 to 0.9/1000 LB in 2008-2017 but the case-fatality rate remained unchanged, (8/119 vs 7/90), at 7%. Among the 209 patients identified during 1997-2017 with sepsis or meningitis the most common organisms were Group B streptococci (40%, 84/209), S. aureus (16%, 33/209) and E. coli (9%, 18/209). The incidence of Group B streptococci infections went from 0.9/1000 live births 1987-1996 to 0.45/1000 live births 1997-2017 and all cases were within 72?h. The proportion of extremely preterm infants (
