From: Practices and intravascular catheter infection during on- and off-hours in critically ill patients
Adjusted MCRI, CRBSI and colonization hazard risk for off-hours in CVCs and ACs. CI: confidence interval. MCRI: major catheter-related bloodstream infection. CRBSI: catheter-related bloodstream infection. CVC: central venous catheter. AC: arterial catheter. A hazard ratio (HR) > 1 indicated an increased risk for off-hours compared to on-hours. Adjustment variables were the following: gender, SAPS II, insertion site, experience of the operator, skin antisepsis, CHG-impregnated dressings, time from ICU admission to catheter insertion, mechanical ventilation and vasopressor at insertion
