Description
Summary:Background. There is a paucity of data on the aetiology of neonatal sepsis in sub-Saharan Africa. Objectives. To investigate the incidence, aetiology and outcomes of physician- diagnosed sepsis in hospitalised neonates who had previously been discharged home after delivery in Soweto, South Africa. Methods. A retrospective review using data abstracted from clinical and laboratory databases identified physician-diagnosed sepsis cases in neonates admitted to the general paediatric wards at Chris Hani Baragwanath Academic Hospital from January 2015 to September 2016. Neonates with physician-diagnosed sepsis were categorised into two groups based on putative pathogens recovered from blood and/or cerebrospinal fluid specimens: (i) culture-confirmed sepsis; and (ii) culture- negative sepsis. Results. Of 1 826 neonatal admissions, 1 025 (56.2%) had physician-diagnosed sepsis: 166 (16.2%) with culture-confirmed sepsis and 859 (83.8%) with culture-negative neonatal sepsis. The commonest pathogens causing culture-confirmed neonatal sepsis were Streptococcus viridans (n=53; 26.5%), S. agalactiae (n=38; 19.0%), and Staphylococcus aureus (n=25; 12.5%). The case fatality rates for culture-confirmed sepsis and culture-negative sepsis were 10.8% (18/166) and 2.6% (22/859), respectively. The odds of death occurring during hospitalisation was 10-fold (95% confidence interval 3.7 - 26.9) higher in neonates with culture-confirmed sepsis compared with culture-negative sepsis. Conclusions. In our setting, physician-diagnosed sepsis represents a huge disease burden in previously healthy neonates hospitalised from home. Most sepsis cases were attributed to S. viridans, S. agalactiae and S. aureus.
