Short-term dialysis catheter versus central venous catheter infections in ICU patients: a post hoc analysis of individual data of 4 multi-centric randomized trials

Résumé

PURPOSE: Little is known on catheter-related infections associated with short-term dialysis catheters (DC). Recommendations for infection prevention are mostly derived from those related to central venous catheters (CVC). A comparison of infectious risk of DCs and CVCs would be instrumental for improving infection control prevention strategies. This study aimed to describe differences in infectious risk between DC and CVC. METHODS: We used individual data from 4 multicenter randomized controlled trials in intensive care units (ICUs) that evaluated various prevention strategies regarding colonization, major catheter-related infections (MCRI) and catheter-related bloodstream infections (CR-BSI). We selected only catheters with non-chlorhexidine gluconate impregnated dressings. A marginal Cox model for clustered data was used for the evaluation of the daily hazard rate for catheter-tip colonization, MCRI and CR-BSI. RESULTS: We included 3029 patients and 4148 catheters (31,547 catheter-days) which comprised 1872 DCs and 2276 CVCs. After adjustment on confounders, we identified an increased risk in DC compared to CVC for colonization (HR 1.45, 95% CI 1.03-2.04, p = 0.04) and for MCRI (HR 2.97, 95% CI 1.03-8.51, p = 0.04) in the first 7 days of catheter maintenance. The daily hazard rate for colonization and MCRI was generally higher for DC in the first catheter-days, whereas it was similar between DC and CVC for longer catheterizations. CONCLUSIONS: The daily risk of colonization and MCRI was significantly higher in DC compared to CVC within the first 7 days of catheter maintenance. Targeted prevention strategies for DC should mostly focus on the period following the insertion.
