Résumé
More than 160,000 central-line-associated bloodstream infections (CLABSIs) are estimated for Europe each year, leading to about 25,000 deaths. To characterize the contamination of administration sets in suspected CLABSI cases in the intensive care unit (ICU). In ICU patients (from February 2017 to February 2018) with suspected CLABSI, all sampled central venous catheters (CVCs) were examined in four segments (from CVC tip to connected tubing systems) for contamination. A risk factor analysis using binary logistic regression was performed. Fifty-two consecutively sampled CVCs with 1004 elements were analysed with 45 elements being positive for at least one micro-organism (4.48%). There was a significant association with the duration of catheterization (P = 0.038, N = 50) with a daily increase of contamination risk by 11.5% (odds ratio: 1.115). The mean number of CVC manipulations was 40 within 72 h (standard deviation: 20.5), with no association with contamination risk (P = 0.381). The contamination risk of the CVC segments decreased from proximal to distal. Non-replaceable components of the CVC had a high risk (14 times higher; P = 0.01). A significant positive correlation was detected between positive tip cultures and microbial growth in the administration set (r(49) = 0.437; P = 0.001). Although only a minority of CLABSI-suspect patients had positive blood cultures, the contamination rate of CVCs and administration set was high, possibly indicating a relevant underreporting. The finding of identical species in adjacent segments underlines the role of upward or downward spread of micro-organisms within the tubes; therefore, aseptic tasks should be emphasized.

BACKGROUND
BACKGROUND

AIM
OBJECTIVE
To characterize the contamination of administration sets in suspected CLABSI cases in the intensive care unit (ICU).
METHODS
METHODS
In ICU patients (from February 2017 to February 2018) with suspected CLABSI, all sampled central venous catheters (CVCs) were examined in four segments (from CVC tip to connected tubing systems) for contamination. A risk factor analysis using binary logistic regression was performed.
FINDINGS
RESULTS
Fifty-two consecutively sampled CVCs with 1004 elements were analysed with 45 elements being positive for at least one micro-organism (4.48%). There was a significant association with the duration of catheterization (P = 0.038, N = 50) with a daily increase of contamination risk by 11.5% (odds ratio: 1.115). The mean number of CVC manipulations was 40 within 72 h (standard deviation: 20.5), with no association with contamination risk (P = 0.381). The contamination risk of the CVC segments decreased from proximal to distal. Non-replaceable components of the CVC had a high risk (14 times higher; P = 0.01). A significant positive correlation was detected between positive tip cultures and microbial growth in the administration set (r(49) = 0.437; P = 0.001).
CONCLUSION
CONCLUSIONS
Although only a minority of CLABSI-suspect patients had positive blood cultures, the contamination rate of CVCs and administration set was high, possibly indicating a relevant underreporting. The finding of identical species in adjacent segments underlines the role of upward or downward spread of micro-organisms within the tubes; therefore, aseptic tasks should be emphasized.
