Prévention des septicémies nosocomiales sur cathéters veineux centraux dans une unité de réanimation néonatale : impact d'une procédure d'information

Abstract

Objective Few studies have evaluated the impact of an information and prevention process specifically aimed at neonatalogists and nurses working in a neonatal intensive care unit (NICU) towards the prophylaxis of nosocomial bloodstream infections. Our objective was first to analyze nosocomial infections within our unit, and secondly to evaluate the impact of a monthly report providing information related to the number and characteristics of such infections. Participants and methods A prospective study was performed in the NICU of Angers University Hospital during 2 six-month periods. All cases of nosocomial bloodstream infections and their characteristics were analyzed. We then published a nosocomial infections report every month during the second period, in order to inform the medical staff and nurses of the results. The impact of the information and prevention process was evaluated by comparing the results between the 2 periods. We also assessed the staff's interest by questionnaire. Results Two hundred and fifty-four (first period) and 240 (second period) patients were included. A decrease in the specific incidence rate and density of catheter related bloodstream infections was observed between the 2 periods, especially for preterms with a birth weight < 1000 g and gestational age < 28 SA ( P < 0.01). Coagulase negative Staphylococcus was identified in 82.3% and 62.5% of cases respectively. 54% of the members of staff expressed their concerns related to the findings and were very interested to read about the observations made during the study. Conclusion This original process seems to be both effective and inexpensive, and can be easily reproduced to decrease the frequency of bloodstream infections in NICU. However, its long-term impact still needs to be evaluated.
