Prevention of central line–associated bloodstream infections relies on a bundle that combines several proven practices to stop infection at multiple points in the line’s life. The elements listed—aseptic hand hygiene, chlorhexidine skin antisepsis, maximal barrier precautions during insertion, proper line maintenance, and daily assessment for removal—work together to reduce infection risk. Aseptic hand hygiene lowers the chance of transferring pathogens to the catheter site; chlorhexidine for skin antisepsis decreases the skin’s microbial load where the line enters; maximal barrier precautions create a sterile field during insertion to prevent introduction of organisms; proper line maintenance includes meticulous dressing care, hub disinfection before access, and routine line care to keep the surface and connections clean; and daily assessment for removal ensures the line isn’t kept in place longer than needed, cutting down the dwell time that can allow infection to develop. Together, these practices address insertion, care, and timely removal—the key stages where infections can start. Sterile technique alone misses ongoing maintenance and timely removal, so it’s not sufficient by itself. Routine antibiotic prophylaxis for all patients is not recommended because it hasn’t shown consistent benefit and can promote resistance and other harms. No intervention would obviously fail to reduce infection risk.
