Which practice helps prevent cross-contamination during wound care?

• A. Hand hygiene before and after
• B. Sharing dressings between patients
• C. Reusing contaminated equipment
• D. Skipping PPE

Answer: (A)

Hand hygiene before and after wound care is the key practice for preventing cross-contamination. Hands are the main vehicle for transferring bacteria and other pathogens between patients and between the wound and the environment. Cleaning hands with soap and water or an appropriate antiseptic rub before touching a wound and after completing care or removing gloves dramatically reduces the chance of introducing infection to a patient or acquiring pathogens yourself. Other options would increase risk: sharing dressings can spread organisms between patients; reusing contaminated equipment can transfer microbes; skipping PPE removes a vital barrier that protects both patient and caregiver from exposure.
