Recent Techniques for Diagnosing Central Venous Catheter-related Bloodstream Infections in Children
Evaluation of Recent Techniques for Diagnosing Central Venous Catheter-related Bloodstream Infections in Critically Ill Children

Removal of a central venous catheter (CVC) is often useful to prove its responsibility in a bloodstream infection. To avoid unnecessary removal of CVC, some catheter-spearing diagnostic methods have been recently developed. The aim of the study is to evaluate three catheter-spearing diagnostic methods in critically ill children: 1) the measurement of the differential time to positivity between a blood culture drawn from a peripherical vein and another one drawn through the CVC; 2) the exam of a blood sample drawn for the CVC and stained by acridine orange leucocyte cytospin test; 3) the semi-quantitative skin culture of the area around the insertion site of the CVC.

Samples for the three techniques described above will be collected from the children admitted in Pediatric Intensive Care Unit with a CVC for more than 48 hours and with clinical or biological signs of systemic infection. Any investigation required to determine the origin of the infection will be performed, according to physician's judgement. If the CVC is removed or changed on a guide wire, a quantitative culture of the distal segment will be performed.

All the patients with a bloodstream infection and sampled according to the protocol will be included for statistical analysis. The physician and an independent medical expert will analyse if the bloodstream infection is CVC-related or not, according to the reference standard, by analysis of the clinical and bacteriological data, blinded towards the three studied techniques. The most optimal threshold will be determined and the sensibility, the specificity, the positive and negative predictable value of the three techniques will be calculated. Then sensibility of these three techniques will be compared.
