What technique is essential for preventing catheter-related bloodstream infections (CRBSIs)?

The essential technique for preventing catheter-related bloodstream infections (CRBSIs) is strict adherence to aseptic technique during insertion and maintenance. This practice is crucial because CRBSIs often occur when pathogens are introduced into the bloodstream during the insertion of the catheter or when the catheter is accessed for use.

Aseptic technique involves a series of specific practices and procedures performed to minimize contamination by pathogens. This includes proper hand hygiene, the use of sterile equipment, appropriate skin antisepsis at the insertion site, and maintenance of a sterile environment throughout the entire duration the catheter is in place. These measures are particularly important given that any breach in sterile technique can provide an entry point for bacteria, leading to potentially severe infections.

In contrast, the other choices, while related to vascular access care, do not address the fundamental preventive strategy as effectively. For example, frequent catheter changes may not significantly reduce infection rates if aseptic technique is not consistently applied. Using larger gauge needles can be relevant to the size of the catheter and vein used but does not directly relate to infection prevention. Reducing the number of vascular access attempts can help minimize tissue trauma and potential infection, but it is not a replacement for stringent aseptic practices. Thus, the primary focus on aseptic technique is integral
