DRS100: Dressings and Dressing Changes for VADs

1. Why the dressing is a clinical intervention
The dressing is the sterile barrier between the patient's bloodstream and the outside environment. It performs three jobs simultaneously: it protects the insertion site from extraluminal microbial contamination, it secures the device to prevent micromotion and dislodgement, and it permits surveillance of the site. A dressing that is lifted at the edges, damp, or visibly soiled is not a minor housekeeping issue — it is an open pathway for skin flora to migrate along the catheter tract toward the bloodstream.
Extraluminal microbial migration from the skin is the dominant mechanism of catheter-related infection in the first 7–10 days after insertion, which is precisely why insertion-site skin antisepsis and dressing integrity carry such weight in every CLABSI-prevention bundle. A large share of the microorganisms that cause short-term catheter-related bloodstream infection originate at the skin insertion site. The dressing, therefore, is one of the highest-yield infection-control tools at the bedside.
The dressing is infection control, securement, and monitoring in one. If any of those three functions is compromised, the dressing has failed and must be replaced regardless of the calendar.
