What evidence-based practice helps prevent Catheter-Related Blood Stream Infection (CRBSI)?

The best choice to prevent Catheter-Related Blood Stream Infection (CRBSI) is the removal of the central line when it is no longer necessary. This is based on evidence that the longer a catheter is in place, the higher the risk of infection. Therefore, timely removal of central lines can significantly reduce the chances of developing CRBSI, as it eliminates the potential entry point for pathogens.

While other practices listed may play a role in infection control, they do not specifically address the inherent risk associated with the duration of catheter use. Using sterilized needles is important for preventing introduction of bacteria, but it doesn’t directly relate to the continued presence of a catheter. Placement of a catheter at the femoral site can actually be associated with a higher risk of infection compared to other sites like the subclavian or internal jugular veins. Regular cleaning of the catheter site with alcohol is an essential practice for maintaining hygiene around the catheter, but it cannot override the risk introduced by leaving an unnecessary central line in place for an extended period. Hence, the proactive approach of removing the catheter when it is no longer needed stands out as the most effective evidence-based practice for preventing CRBSI.
