Which step is involved in the technique for hand sanitization as per 797?

Using an alcohol-based hand rub is a critical step in the hand sanitization technique as outlined in USP Chapter <797>, which provides guidelines for compounding sterile preparations. Alcohol-based hand rubs contain a significant percentage of alcohol, which is effective in rapidly reducing the number of germs on the skin. This method is preferred in many healthcare settings because it is not only efficient in killing bacteria and viruses, but it also requires less time compared to traditional handwashing.

The operational guidelines in USP <797> emphasize that proper hand hygiene is essential to prevent contamination in sterile compounding. The use of an alcohol-based hand rub is specifically recommended for sanitizing hands in situations where there is no visible dirt or soil, making it a convenient option for healthcare professionals working in sterile environments.

While scrubbing with soap, rinsing with water, and applying hand lotion may be relevant in other contexts of hygiene or skin care, they do not specifically align with the hand sanitization protocols prescribed in <797> for sterile compounding situations. Hand sanitization focuses specifically on the rapid and effective reduction of microbial load, which is best achieved through the use of an alcohol-based solution.
