Which action is the most important to prevent the spread of infection in dialysis settings?

• A. Sterilize dialyzers before use
• B. Wear gloves at all times
• C. Use antibiotics prophylactically
• D. Perform hand hygiene

Answer: (D)

Preventing infection spread in a dialysis setting hinges on interrupting transmission at the point of contact. Hand hygiene directly stops pathogens from moving between patients, equipment, and surfaces. Washing with soap and water or using an alcohol-based hand rub before touching a patient, after patient contact, after removing gloves, and after exposure to blood or body fluids dramatically reduces the chance of transferring microbes. Gloves are important as a barrier, but they don’t replace hand hygiene because gloves can have small tears and can become contaminated during use; hand hygiene is required before putting gloves on and after taking them off. While sterilizing equipment and avoiding unnecessary antibiotic use matter for overall infection control, they don’t have the universal, day-to-day impact that proper hand hygiene does. In short, good hand hygiene is the most effective, consistently applicable measure to prevent infection spread in dialysis care.
