Which technique is effective for preventing vascular access infection?

Swabbing the access site with disinfectant before each use is an effective technique for preventing vascular access infection because it reduces the number of pathogens present on the skin surface at the site where the access will occur. This is critical in creating a sterile environment, as microorganisms introduced during access can lead to serious infections. The use of a disinfectant, such as alcohol or chlorhexidine, helps to significantly minimize the risk of bacterial colonization and entry into the bloodstream.

Proper skin antisepsis is a cornerstone of infection prevention in procedures involving vascular access, as it disrupts the potential for pathogens to enter the vascular system. Regularly applying this practice before each use ensures that any transient or resident flora are adequately controlled, thereby directly contributing to patient safety and reducing the risks associated with vascular access procedures.
