Fig 1. Trends in neonatal hospital-acquired bloodstream infection (HA-BSI) rate, pathogen yield and blood culture contamination rate (2009–2018).

Fig 1

*HA-BSI rate calculated using number of HA-BSI episodes over total inpatient-days multiplied by 1000, from 2009–2018. HA-BSI comparisons made using Poisson regression. Pathogen yield and blood culture contamination rate calculated as number of pathogen-containing and contaminant-containing blood cultures respectively, as a proportion of all blood cultures submitted from 2009–2018; compared using a χ2 test for linear trend. Two-sided p-values were used.
