The role of central venous catheters in confirmed paediatric bloodstream infections


Virano, S., Scolfaro, C., Garazzino, S., De Intinis, C., Ghisetti, V., Raffaldi, I., Calitri, C. and Tovo, P.A. (2015) Medical care related laboratory-confirmed bloodstream infections in paediatrics. Le Infezioni in Medicina. 23(2), p.117-24.


The aim of this survey was to describe the incidence, epidemiology, microbiology, risk factors and outcome of medical care related laboratory-confirmed bloodstream infections (LCBIs) observed during a twelve-month prospective study in a Paediatric Teaching Hospital in Turin, Italy. Inclusion criteria were clinical signs of sepsis and positivity of one or more of the following tests: blood culture, polymerase chain reaction for bacterial and fungal DNA on blood, and culture on intravascular device tips. In all, 140 episodes of sepsis were documented in 131 children: 37 (26.4%) were healthcare outpatient-associated, 91 (65.0%) healthcare-associated and 12 (8.6%) community-acquired. The overall incidence of healthcare-associated LCBIs was 13.6/1,000 hospitalized patients and incidence density 1.4/1,000 inpatient days. The overall mortality was 3.9%. Forty-seven (36.7%) episodes involved newborns and 107 (83.6%) episodes were observed in children with an indwelling central venous catheter. Coagulase-negative staphylococci (26.8%), Staphylococcus aureus (15.2%), Escherichia coli (8.7%) and Candida spp. (7.2%) were responsible for the majority of cases. 9.5% of S. aureus isolates were methicillin-resistant and 6.5% of Gram negatives were extended-spectrum beta-lactamase-producing. Incidence and epidemiology of medical care related LCBIs were similar to the existing literature data. LCBIs caused by antibiotic-resistant microorganisms were fewer and mortality rate was lower. Most of the LCBIs recorded involved newborns and oncological children.
