Hand hygiene is essential for nurses to reduce the transmission of microorganisms, hospital-acquired infections, and the risk of exposure to infectious diseases. While handwashing with soap and water is crucial, especially when hands are visibly soiled, alcohol-based hand rubs or sanitizers offer a convenient and effective alternative. Alcohol-based products are recommended when hands are not visibly soiled, killing both good and bad germs, although good germs quickly return. This method is also less irritating to the skin and reduces the risk of bacteria transmission. However, studies have shown that alcohol-based rubs may be ineffective against certain spores, such as C. difficile, in which case soap and water remain the preferred option. Ultimately, both handwashing techniques are essential for nurses to maintain a safe and hygienic environment for themselves and their patients.
Characteristics of mechanical hand washing vs. alcohol-based hand washing for nurses:
| Characteristics | Values |
|---|---|
| Effectiveness against germs | Alcohol-based hand washing is effective against most germs, including good and bad germs, whereas mechanical hand washing may be preferred when hands are visibly soiled or contaminated with specific infections like C. diff. |
| Skin irritation | Alcohol-based hand washing can be less irritating and drying to the skin than mechanical hand washing. |
| Technique | Mechanical hand washing involves using soap and running water for at least 15-20 seconds, ensuring all surfaces of the hands and fingers are covered. Alcohol-based hand washing involves applying the recommended amount of product (3-5 mL) and rubbing vigorously for about 20 seconds until hands are dry. |
| Accessibility | Mechanical hand washing requires access to soap and running water, while alcohol-based hand washing can be used when soap and water are not available. |
| Cost-effectiveness | Mechanical hand washing is the most cost-effective way to prevent the transmission of infections. |

Alcohol-based hand sanitizers are recommended when hands are not visibly soiled
Alcohol-based hand sanitizers are a convenient and effective way to maintain hand hygiene, especially when hands are not visibly soiled. They are widely recommended by organizations like the CDC and WHO, particularly in healthcare settings, to prevent the transmission of microorganisms, hospital-acquired infections, and the risk of exposure to infectious diseases.
In healthcare environments, alcohol-based hand rubs are often used as a substitute for handwashing due to their convenience and ease of use. They do not require water or hand drying, making them a popular choice for healthcare professionals striving for a safer environment. Additionally, alcohol-based sanitizers are less irritating and drying to the skin than frequent handwashing with soap and water. This is particularly important in healthcare settings, where skin irritation is common due to frequent handwashing, glove use, and exposure to water, soap, and disinfectants.
However, it is important to note that alcohol-based hand rubs may not be effective against certain pathogens or biological materials, especially when hands are heavily contaminated. In such cases, antimicrobial soaps are recommended as they can be more effective than alcohol-based sanitizers. Additionally, handwashing with soap and water is crucial before donning sterile gloves, as alcohol-based products alone may not sufficiently clean the hands and forearms.
Overall, alcohol-based hand sanitizers are a recommended and convenient option for hand hygiene when hands are not visibly soiled. However, when hands are visibly dirty or heavily contaminated, handwashing with soap and water is the preferred method to ensure proper cleaning and the removal of germs, dirt, and grime.

Handwashing with soap and water is recommended when hands are visibly soiled
Hand hygiene is paramount in reducing the transmission of microorganisms, hospital-acquired infections, and the risk of exposure to infectious diseases. According to the CDC, hand hygiene involves cleansing hands with soap and water, antiseptic hand washes, or alcohol-based hand rubs.
When hands are visibly soiled, the CDC and WHO guidelines recommend handwashing with soap and water for at least 15 to 20 seconds. It is important to use a vigorous motion to create friction and ensure that all surfaces of the hands and fingers are covered. Warm water should be used, and hands should be kept lower than the elbows to prevent cross-contamination from water running back. After washing, hands should be patted dry, and proper techniques should be followed to avoid recontamination, such as using a towel to turn off the faucet.
In healthcare settings, handwashing with soap and water is crucial when hands are contaminated with blood or other bodily fluids. It is also essential before eating, after using the restroom, and when there has been potential exposure to specific pathogens, such as Clostridium difficile, Norovirus, or Bacillus anthracis.
While alcohol-based hand rubs are effective at killing germs, they are recommended for hand hygiene when hands are not visibly soiled. These products kill both good and bad germs, but the good germs quickly return to the hands. Additionally, alcohol-based rubs should not be used when hands are visibly soiled as they may not effectively remove all contaminants.

Handwashing with soap and water is more effective at removing C. difficile spores
Hand hygiene is essential in healthcare settings to prevent the transmission of microorganisms, hospital-acquired infections, and the risk of exposure to infectious diseases. While alcohol-based hand sanitizers are convenient and effective at killing most germs, they may not be sufficient for all types of pathogens.
Clostridium difficile (C. diff) is a challenging bacterium to eliminate. It can cause watery diarrhea, stomach cramps, fever, and potentially life-threatening complications. C. diff forms a tough shell, known as a spore, allowing it to survive as it passes through the stomach's acids. This protective spore makes it more challenging to eradicate than other bacteria.
Several studies have found alcohol-based hand rubs to be ineffective at removing or inactivating C. diff spores from contaminated hands compared to handwashing with soap and water. Handwashing with soap and water is, therefore, the recommended method to prevent the spread of C. diff. The mechanical action of rubbing the hands together and the chemical action of the soap combine to dislodge and remove the spores from the skin.
It is important to note that handwashing with soap and water is generally recommended when hands are visibly soiled, contaminated with blood or other bodily fluids, or after using the toilet. In healthcare settings, this is crucial to prevent the spread of C. diff and other pathogens. Handwashing with soap and water is also essential when caring for patients with C. diff infections, especially during outbreaks of diarrhoea, as it helps to manage the spread of the disease.
While alcohol-based hand rubs are less effective against C. diff spores, they are still an essential component of hand hygiene in healthcare settings. They are more convenient and quicker to use than handwashing, and they are effective at killing most germs, including the non-spore form of C. diff. Therefore, alcohol-based hand rubs remain the preferred method for routine hand hygiene in healthcare settings, while handwashing with soap and water is reserved for specific situations, such as visible soiling or suspected exposure to spore-forming pathogens.

Handwashing with soap and water is more drying and irritating to the skin
Alcohol-based hand sanitisers are quick and effective at killing both good and bad germs, but the good germs quickly return to the hands. Handwashing with soap and water, on the other hand, can be more time-consuming and requires a specific technique to ensure proper hand hygiene. The CDC recommends washing hands with soap and water for at least 15 to 20 seconds, ensuring that all surfaces of the hands and fingers are covered. This vigorous motion creates friction, which is essential for effective handwashing. However, this process can strip the skin of its natural oils, leading to dryness and irritation, especially with frequent washing.
In addition, hot water should be avoided when washing hands, as it can further contribute to skin dryness and irritation. Patting hands dry instead of rubbing them can also help reduce skin irritation. Healthcare workers are advised to use hand lotions to prevent and alleviate skin dryness caused by frequent handwashing.
While alcohol-based hand sanitisers are generally gentler on the skin, they may not be suitable for all situations. For example, the CDC and WHO guidelines recommend handwashing with soap and water when hands are visibly soiled, as alcohol-based hand rubs are ineffective at removing certain types of spores and contamination.
Overall, while handwashing with soap and water is more drying and irritating to the skin, it is still an essential practice in healthcare settings to prevent the transmission of infections and ensure patient safety.

Handwashing with soap and water is more time-consuming and less convenient
Alcohol-based hand sanitizers are quick and easy to use, requiring just a few seconds to rub the product onto the hands and allow it to dry. In contrast, handwashing with soap and water involves multiple steps, including wetting the hands, lathering with soap, scrubbing for at least 15 to 20 seconds, and drying. This process can take significantly longer, especially when considering the need to locate a sink, access running water, and ensure proper technique to avoid cross-contamination.
For nurses and other healthcare providers, time is often critical, and the convenience of alcohol-based sanitizers cannot be overstated. Sanitizers can be used at a moment's notice, without interrupting their workflow or requiring them to move to a different location. This is especially important in fast-paced medical environments, such as emergency rooms or intensive care units, where every second counts.
Additionally, handwashing with soap and water may not always be feasible in certain healthcare settings. For example, nurses working in community or home-based care may not always have immediate access to a sink or clean water. In such cases, carrying a small bottle of hand sanitizer provides a practical and efficient solution for maintaining hand hygiene.
While handwashing with soap and water is crucial in certain situations, such as when hands are visibly soiled or contaminated with blood or bodily fluids, alcohol-based hand sanitizers offer a faster and more convenient alternative for routine hand hygiene, helping nurses maintain high standards of cleanliness and infection control.
