Eggimann P, et al. - Researchers assessed rates of catheter (central venous and arterial)-associated bloodstream infection, expressed as incidence density rates per 1,000 catheter-days measured as part of a surveillance program, in relation to incrementally introducing chlorhexidine (CHG) dressings (sponge or gel) in addition to an ongoing catheter bundle in this real-world data study. They compared infection rates over time by using Poisson regression models. A sustained 11-year attenuation of all catheter-related bloodstream infections was evident in relation to the addition of chlorhexidine dressings to all CVC and arterial lines to an ongoing catheter bundle. In line with current guidance, systematic use of CHG dressings on all catheters of intensive care unit patients was supported.
