When should you perform hand hygiene with alcohol-based hand rub instead of soap and water?

• A. When hands are not visibly dirty or soiled and no C. difficile risk
• B. When hands are visibly dirty
• C. After using the restroom
• D. After patient contact

Answer: (A)

Alcohol-based hand rub is preferred for hand hygiene when hands are not visibly dirty and there’s no risk of C. difficile, because it quickly and effectively reduces most pathogens with less time and effort than washing. The scenario described matches that: hands are clean to the eye and there’s no exposure to C. difficile spores. If hands are visibly dirty or soiled, soap and water should be used since mechanical washing removes dirt and spores more reliably than an alcohol rub. C. difficile spores are resistant to alcohol, so in settings where spore risk exists, soap and water is the safer choice. After restroom use or after patient contact, you apply the same idea: use soap and water if hands are dirty or spore risk is present; otherwise, an alcohol-based rub is acceptable for routine decontamination when hands are clean.
