How can you prevent catheter-related bloodstream infections (CRBSIs)?

The prevention of catheter-related bloodstream infections (CRBSIs) predominantly hinges on the application of proper insertion techniques and the maintenance of sterile conditions. This includes aspects such as performing hand hygiene before and after procedures, using sterile equipment, applying antiseptic solutions to the insertion site, and ensuring that the catheter is inserted using appropriate practices to minimize contamination during the process. Furthermore, maintaining the sterility of the catheter during its use, including secure dressing over the insertion site, helps reduce the risk of microbial entry.

While other strategies may seem relevant in the context of IV therapy, they are less effective in directly preventing CRBSIs. The use of broad-spectrum antibiotics before insertion does not prevent the risk of infections that might emerge from improper sterile technique. Frequent dressing changes could potentially increase the risk of introducing pathogens to the site if not performed under sterile conditions. Limiting patient mobility may not be a practical or necessary approach, as it does not directly correlate to preventing infections and may hinder patient comfort and mobility without a clear benefit. Therefore, focusing on proper insertion techniques and maintaining sterility is the most established and effective method for preventing CRBSIs.
