Fully automated algorithm developed for CRBSI, CLABSI and intensive care unit (ICU) onset BSI detection for patients in the ICU. 1. List of common commensals from the CDC NHSN. 2. Only short term central vascular catheters are considered. 3. Specimens included : respiratory samples, urinary samples, central nervous system samples, abdominal samples, bone and joints samples. 4. This rule applies only to true pathogens and not to common commensal (even if classified as true pathogen on step 3). ICU: intensive care unit; BSI: bloodstream infection; CVC: central vascular catheter; CLABSI: central line associated Bloodstream Infection; CRBSI: Catheter related bloodstream infection; CC: common commensals
