Which statement accurately describes hand hygiene’s role in infection control?

• A. It is the most effective method to prevent infection by cleansing hands to remove pathogens
• B. It is only necessary when hands are visibly dirty
• C. It should be avoided when gloves are available
• D. It is primarily for cosmetic reasons

Answer: (A)

Hand hygiene is the single most effective infection prevention measure. Thoroughly cleansing the hands removes and reduces the number of pathogens that can be transmitted to patients, healthcare workers, and the surrounding environment. Because hands are the primary vehicle for spreading infections, routine, proper hand hygiene dramatically lowers the risk of healthcare-associated infections and outbreaks.

It should be done before touching a patient to protect them from germs you may carry, and after touching a patient or their surroundings to prevent spreading contaminants to others. It is also essential after removing gloves, since gloves can be punctured or become contaminated during care, and hand hygiene helps ensure any pathogens on gloves don’t transfer to you or to other patients.

It is not only performed when hands are visibly dirty, and gloves do not replace the need for hand hygiene. In many situations, an alcohol-based hand rub is used for quick decontamination, but soap and water is required when hands are visibly dirty or when exposure to certain organisms (like C. difficile) necessitates thorough removal of contaminants.
