. Resume-objectifs,

, La contamination d'hémoculture aux urgences pédiatriques est fréquente avec des facteurs de risque bien définis et un impact économique et thérapeutique important. L'objectif de notre

, Pour cela nous avons réalisé une étude rétrospective observationnelle chez tous les enfants ayant eu au moins une hémoculture prélevée aux urgences pédiatriques du CHU de Bordeaux en 2017 dont le résultat était positif

, Les contaminants les plus fréquents étaient les staphylocoques et streptocoques. La majorité des patients ayant une hémoculture contaminée avaient une infection respiratoire, et après réception du résultat de l'hémoculture, 31% étaient hospitalisés plus de 48 heures et 24% avaient une antibiothérapie prolongée. En comparaison avec les patients présentant une bactériémie, les patients ayant une hémoculture contaminée présentaient moins d'antécédent médical, une fièvre et une CRP moins élevées et il n, Parmi les 2068 hémocultures prélevées aux urgences pédiatriques en 2017, 91 étaient positives avec 23 bactériémies (1,1%) et 68 contaminations (3,3%)

, Notre étude souligne l'impact négatif des hémocultures contaminées aux urgences pédiatriques et la nécessité d'améliorer leur prescription et réalisation. Nous avons créé un protocole de prescription d'hémocultures aux urgences pédiatriques du CHU de Bordeaux que nous allons mettre en place et dont nous évaluerons l'efficacité
