Which of the following is false regarding handwashing?

• A. Alcohol-based hand gel can be used in place of soap and water on hands that are visibly dirty
• B. Soap and water must be used when hands are visibly dirty
• C. Alcohol-based hand gel is recommended for routine hygiene when hands are not visibly dirty
• D. Hand hygiene should be performed before and after patient contact

Answer: (A)

The main idea here is when to use soap and water versus an alcohol-based hand gel in clinical practice. Alcohol-based hand rub is great for quick, routine hygiene when hands are not visibly dirty because it rapidly reduces most microbes with a simple rub. But when hands are visibly dirty or contaminated, washing with soap and water is required because the physical removal of soil and microbes by rinsing is more effective than sanitizer alone. So, the statement about using alcohol-based gel in place of soap and water on hands that are visibly dirty is false. In dirty conditions, soap and water must be used. The other guidelines are correct: use soap and water whenever hands are visibly dirty; use alcohol-based hand gel for routine hygiene when hands are not visibly dirty; and perform hand hygiene before and after patient contact to prevent cross-contamination. In dental radiology, this means washing hands before patient contact and after glove removal, and using hand gel between patients when hands aren’t visibly soiled.
