[Prevention and nursing care of central line-associated bloodstream infections in critically ill patients].

Catheter-related bloodstream infections are associated with significantly increased morbidity, mortality, and expenditures. Such infections are a serious threat to patient safety in the intensive care unit. This review describes the latest protocols related to preventing and treating central venous catheter-associated bloodstream infections in critically ill patients. According to 2011 Center for Disease Control (CDC) guidelines and central line care bundles by the institute for healthcare improvement (IHI), prevention measures for catheter-related bloodstream infections include the following: hand hygiene, maximal barrier precautions insertion, chlorhexidine skin antisepsis, optimal catheter site selection, proper catheter maintenance, insertion site care, and daily review of line necessity, with prompt removal of unnecessary lines. These are important and effective infection prevention measures. Guidelines and care bundles also recommend organizing care modules based on unit characteristics; integrating resources and empirical measures; education and training to promote comprehensive implementation; and auditing and monitoring to ensure staff continue to follow procedures. Effectively preventing central venous catheter-related bloodstream infections can enhance care quality and move healthcare closer to achieving the goal of zero tolerance.
