When is alcohol-based antiseptic appropriate for hand hygiene?

Alcohol-based antiseptics are appropriate for hand hygiene primarily before and after patient contact because they are effective in reducing the number of microorganisms on the skin, which is essential in preventing the spread of infections in healthcare settings. This practice supports the objective of maintaining a sterile field and protecting both patients and healthcare workers from potential infections.

Alcohol-based antiseptics work well in many situations; however, they are not effective when hands are visibly dirty or soiled with organic material, such as blood or dirt. In such cases, soap and water are necessary to remove these contaminants. Similarly, after using the restroom or following exposure to spore-producing organisms (such as Clostridium difficile), handwashing with soap and water is recommended over alcohol-based antiseptics to ensure complete elimination of pathogens.
