Innovations in Quality Improvement of Intravascular Catheter-Related Bloodstream Infections

AbstractPurpose of reviewSignificant reductions in catheter-related bloodstream infections (CRBSI) have occurred in the United States. Reductions in CRBSIs are attributed to the widespread implementation of the practice-based measures and innovations in the diagnosis, treatment, and prevention of CRBSI.Recent findingsDiagnosis of CRBSI historically required removal of the central venous catheter (CVC) for catheter tip culture. Removing the CVC for CRBSI diagnosis predisposes many patients to potential life-threatening complications. Advances in diagnostic techniques such as culturing catheter hubs, catheter entry site cultures, applying differential time to positivity, molecular diagnostics, biomarkers, and innovative approaches like biosensors on the CVC lumen may provide an alternative to CVC removal. Removal of the CVC is common for the treatment of CRBSI; however, antimicrobial lock therapy is increasingly used as a CVC salvage method. Implementation of newer technology such as antimicrobial coated catheters, chlorhexidine-impregnated dressings, and antiseptic port protectors are crucial for the prevention of CRBSIs. Increasing evidence also support newer sutureless CVC securement devices prevent CRBSIs.SummaryCRBSI remains a significant clinical problem despite advances made in the diagnosis, management, and prevention. Molecular techniques are increasingly being used for pathogen identification in CRBSI, but the optimal diagnostic test remains debatable. Increasing expe...
