In the US, trends in hospitalization rates among pediatric bloodstream infections (BSIs) vary by pathogen and regionally, while overall BSI hospitalization rates did not significantly decline from 2009‒2016, a new study found. Researchers conducted a retrospective cohort study from 2009‒2016 utilizing demographic and microbiology data on inpatients aged <19 years using the Premier Healthcare Database. Hospitalization rate was the number of BSI-positive encounters per 1,000 admissions. They found:
- Among 1,809,751 inpatients encounters from 162 US hospitals, 5,340 (0.30%) had a positive BSI, with community-acquired infections (CAIs) the most common.
- BSI patients were more often aged 1‒5 years and had a complex chronic condition or central line compared to non-BSI patients.
- BSI hospitalization rate declined non-significantly over time.
- Among pathogens, E. coli, methicillin-sensitive Staphylococcus aureus, and Group A Streptococcus significantly increased for non-neonates.
