CDC hand-hygiene guidance reaffirms that consistent hand hygiene at the recommended moments remains one of the most effective ways to prevent healthcare-associated infections. The guidance covers when to use alcohol-based hand rub versus soap and water (for example, with certain spore-forming organisms or visibly soiled hands).
The clinical point is reliability at the key moments — before patient contact, before a clean/aseptic task, after body-fluid exposure risk, after patient contact, and after contact with patient surroundings. Adherence tends to slip during busy periods, which is exactly when transmission risk rises.
Why this matters on shift
Healthcare-associated infections cause real harm and are often transmitted on hands. Reliable hand hygiene at each moment is a simple, high-impact action every nurse controls — and one that protects patients, colleagues, and the nurse.
