    Hand Hygiene

    Hand hygiene is the most important part of practice for health care workers and is the single most effective way to stop the spread of infections; failure to properly perform hand hygiene is the leading cause of HAIs and the spread of multi-drug-resistant organisms (MDROs) (BC Centre for Disease Control, 2014; WHO, 2009a). Hand hygiene is a general term used to describe any action of hand cleaning and refers to the removal or destruction of soil, oil, or organic material, as well as the removal of microbial contamination acquired by contact with patients or the environment. Hand hygiene may be performed using an alcohol-based hand rub (ABHR) or soap and water. A surgical hand scrub is also a method of hand hygiene (WHO, 2009a).

    To break the chain of infection, there are five key moments at which to perform hand hygiene when working in health care, as outlined in Checklist 2 and illustrated in Figure 1.1.

    Checklist 2: Five Key Moments in Hand Hygiene

    Disclaimer: Always review and follow your hospital policy regarding this specific skill.
    Safety considerations:
    • If contact dermatitis occurs, use soap and water for hand hygiene.
    • Instruct patients and family on the importance of hand hygiene, proper technique, and ways to incorporate routines into everyday practice.
    • Certain practices can increase the risk of skin irritation and should be avoided. For example, washing hands regularly with soap and water immediately before or after using an alcohol-based product is not only unnecessary but may lead to dermatitis.
    • Always wash hands whenever in doubt.

    Safety Alert: Factors that Reduce Hand Hygiene Effectiveness

    • Jewellery: Rings and bracelets increase microbial count on hands. Rings also increase the risk of torn or pierced gloves. Jewellery should not be worn during patient care (Longtin, Sax, Allegranzi, Schneider, & Pittet, 2011). All jewellery must be removed. In an instance where a bracelet may not be removed due to religious reasons, the bracelet may be pushed as high as possible above the wrist before performing hand hygiene.
    • Skin integrity: The condition of the hands can influence the effectiveness of hand hygiene, and proper skin care is essential for infection control (Bissett, 2007). Skin cracks, dermatitis, or cuts can trap bacteria and may place patients at an increased risk (CDC, 2007). Inspect hands for cuts and open sores, and cuticles for tears. Open cuts, sores, or abrasions should be covered prior to starting work. Use barrier creams and lotion after patient care to keep skin healthy and hydrated.
    • Artificial nails and nail extenders: Artificial nails and nail extenders increase the viral load of bacteria up to nine times compared with bacteria found on hands. Extenders or artificial nails are not recommended for health care workers (Kennedy, 2013).
    • Nail length: Nails should be a maximum of 1/4-inch long and should not extend past the end of the finger (Patrick & Van Wicklin, 2012). Most microbes on hands come from under the fingernails. Subungual areas (under the fingernails) can harbour higher concentrations of microorganisms (Kennedy, 2013). In addition, long nails are harder to clean and may lead to more frequent puncture in gloves from the thumb and forefinger (Patrick & Van Wicklin, 2012).
    • Nail polish: Nail polish should be freshly applied and be free from chips or cracks. Studies have shown that chipped nail polish and polish older than four days can harbour microorganisms (Patrick & Van Wicklin, 2012).
    • Water temperature and products: Warm water removes less protective oils than hot water, whereas hot water increases the likelihood of skin damage (WHO, 2009a). To prevent contamination, products must be dispensed in a disposable pump container that is not topped up. An adequate amount of soap is required to dissolve fatty materials and oils from hands as water alone is not sufficient to clean soiled hands (WHO, 2009a).

    How to Wash Hands: Types of Hand Hygiene

    Two types of hand hygiene are commonly used in the health care setting: hand hygiene with an alcohol-based hand rub (see Figure 1.2) and hand hygiene with soap and water.

    DSC_1581-150x150.jpg

    Figure 1.2 Alcohol-based hand rub

    Alcohol-based hand rub (ABHR) is a product containing 60% to 90% alcohol concentration and is recommended for hand hygiene in health care settings (CDC, 2012). ABHR is the preferred method of hand hygiene and is more effective than washing hands with soap and water (WHO, 2009a). ABHRs:

    • Kill the majority of germs (including viruses) from hands
    • Require less time to use than soap and water (20 to 30 seconds)
    • Are easy to use and have high levels of availability at the point of care
    • Provide better skin tolerability

    See Checklist 3 for the steps to take when washing hands with ABHR.

    Checklist 3: Hand Hygiene with ABHR

    Disclaimer: Always review and follow your hospital policy regarding this specific skill.
    Safety considerations:
    • Do not use in combination with soap and water. This practice may increase skin irritation.
    • Use ABHR that contains emollients (oils) to help reduce skin irritation and overdrying.
    • Allow hands to dry completely before initiating tasks or applying clean or sterile gloves.
    • ABHR may be used for all five moments in hand hygiene (see Checklist 2) as long as hands are not contaminated or visibly soiled.
    • DO NOT use ABHR if patient is suspected to have or confirmed with Clostridium difficile, norovirus, or Bacillus anthracis. ABHR will not kill spore-forming pathogens.
    Steps

    Hand Hygiene with Soap and Water

    Hand hygiene with water requires soap to dissolve fatty materials and facilitate their subsequent flushing with water. Soap must be rubbed on all surfaces of both hands followed by thorough rinsing and drying, Water alone is not suitable for cleaning soiled hands (WHO, 2009a). The entire procedure should last 40 to 60 seconds and should use soap approved by the health agency. See the steps in Checklist 4.

    Checklist 4: Hand Hygiene with Soap and Water

    Disclaimer: Always review and follow your hospital policy regarding this specific skill.
    Safety considerations:
    • Always wash hands with soap and water if hands are visibly dirty or soiled.
    • When working with patients where Clostridium difficile (CDI), norovirus, or Bacillus anthracis is suspected or confirmed, soap and water must be used. CDI can remain dormant on surfaces for long periods of time.
    • Always use soap and water if hands are exposed to blood or body fluids.
    • Multi-step rubbing techniques using soap and water are required to promote coverage of all surfaces on hands. Friction and rubbing are required to remove oil and debris from hands.

    Non-sterile (Clean) Gloves

    Both hand hygiene and clean glove use are strategies to prevent transmission of infections through hand contact. In the context of patient care, it makes sense to think of glove use and hand hygiene as complementary strategies to prevent transmission of pathogens. Gloves are critical to prevent the transmission of organisms when hand hygiene alone is not enough in an outbreak such as Clostridium difficile or the norovirus, or when a patient has a suspected or known pathogen. Studies have shown that gloves reduce transmission of microbes from the hands of health care workers (PIDAC, 2012).

    Non-sterile gloves are single use and should be applied:

    • Before an aseptic procedure
    • When anticipating contact with blood or body fluid, non-intact skin, secretions, excretions, mucous membranes, or equipment/environmental surfaces contaminated with the above blood or body fluids
    • When in contact with a patient or patient equipment/environment during additional precautions

    Non-sterile gloves should be removed:

    • If gloves are damaged and integrity is compromised
    • When contact with blood, body fluid, non-intact skin, or mucous membranes has ended
    • When contact with a single patient and that patient’s surrounding or a contaminated body site on a patient has ended
    • When there is an indication for hand hygiene

    See Checklist 5 for steps on how to apply non-sterile gloves.

    Checklist 5: Applying Non-Sterile Gloves

    Disclaimer: Always review and follow your hospital policy regarding this specific skill.
    Safety considerations:
    • Hands must be clean and dry before putting on gloves. Gloves do not replace the need for hand hygiene.
    • Hand hygiene must be performed every time gloves are removed. Gloves are not completely free of leaks or 100% tear-proof, and hands may become contaminated when gloves are removed.
    • Gloves are for single patient use and must be removed after caring for one patient. Reuse of gloves has been associated with transmission of antibiotic-resistant organisms.
    • Change or remove gloves if moving from a contaminated site to a non-contaminated site on the same person or if touching the environment.
    • Wear gloves that fit properly. Different sizes are available.
    • Gloves must be removed immediately and discarded in a waste bin after the activity for which they were used and before exiting a patient’s environment.
    • Gloves are not required for health care activities where contact is limited to intact skin, such as taking blood pressure.
    • Indiscriminate or improper glove use (e.g., wearing gloves all the time) has been linked to transmission of pathogens.
    • Gloves should fit snugly around wrists and hands for use with a gown to provide a better skin barrier.

    Latex Allergies and Non-sterile (Clean) Glove Use

    A latex allergy is a reaction to the proteins in natural rubber latex (American Academy of Allergy, Asthma and Immunology, 2014). When people come in contact with latex, an allergic reaction may occur. Most reactions are mild (asthma-like symptoms or contact dermatitis), but there are some rare severe cases (reactions). Many hospitals have moved away from using latex gloves, but latex is commonly used in many health care products such as IV tubing, urinary catheters, syringes, dressings, and bandages. People at risk for developing a latex allergy are:

    • Health care workers and others who frequently wear latex gloves
    • People who have had many surgeries (10+)
    • People who are often exposed to natural rubber latex
    • People with other allergies, such as hay fever (allergic rhinitis), or allergies to certain foods

    Note that powdered latex gloves have also been associated with latex allergies. If an allergy to latex exists, the best treatment is to avoid latex and use a medical alert bracelet to inform others of the allergy (PIDAC, 2012).

    Critical Thinking Exercises

    1. Name four factors that decrease the effectiveness of hand hygiene.
    2. What are two ways to reduce or prevent skin irritation with hand hygiene or non-sterile (clean) glove use?
