Abstract

Paediatricians recognize that using the time-dependant community-acquired versus hospital-acquired bloodstream infection (BSI) dichotomy to guide empiric treatment no longer distinguishes between causative pathogens due to the emergence of healthcare-associated BSI. However, paediatric epidemiological evidence of the aetiology of BSI in relation to hospital-admission in England is lacking. For 12 common BSI-causing pathogens in England, timing of laboratory reports of positive paediatric (3 months-5 years) bacterial blood isolates were linked to in-patient hospital data and plotted in relation to hospital-admission. The majority of linked pathogens (88.6%) were isolated <2 days after hospital admission, including pathogens widely regarded as hospital-acquired: Enterococcus spp. (67.2%)and Klebsiella spp. (88.9%). Neisseria meningitidis, Streptococcus pneumoniae, group A streptococcus and Salmonella spp. were unlikely to cause hospital-acquired BSI. Pathogens commonly associated with hospital-acquired BSI are being isolated <2 days after hospital admission alongside pathogens commonly associated with community-acquired BSI. We confirm that timing of blood samples alone does not differentiate between bacterial pathogens. Additional factors including clinical patient characteristics and healthcare-contact should be considered to help predict the causative pathogen and guide empiric antibiotic therapy.
