© IFIC:2008 Hand Hygiene BASIC CONCEPTS OF INFECTION CONTROL International Federation of Infection Control © IFIC:2008 Objectives Skin flora Impact of hand hygiene (HH) in healthcare-associated infections (HAI) Techniques of HH Compliance Recommendations © IFIC:2008 Background Personal hygiene and environmental cleaning associated with less illness and death Ignaz Semmelweis (1846) demonstrated that washing hands with antiseptic solution reduced mortality due to puerperal endometritis Other researchers demonstrated that healthcare workers (HCWs) can transmit infections through contaminated hands © IFIC:2008 Background Hands are the most frequent route of transmission for pathogens in healthcare settings There have been changes in hand hygiene based on rationale or evidence (mainly products) The main problem is how to improve compliance Compliance is generally low Compliance averages 40%-60% Combined strategies to improve compliance Education Supervision Alcohol based products © IFIC:2008 Skin Flora Transient Superficial layers of the skin Often acquired by HCWs during contact with patients Easily transmitted by contact Most frequently associated with HAI Resident Lives permanently in the deeper layers of the skin (epidermis) More resistant to removal Unlikely to be associated with infections (except in surgery) © IFIC:2008 Skin Flora Hands of HCWs may become colonised or infected with pathogens (e.g., S. aureus, Gram-negative bacilli, or yeast) Transmitted like transient flora - constitutes a serious danger within hospitals Damaged or diseased skin allows multiplication of flora Most dangerous of all situations HCWs with uncovered skin lesions should not have direct contact with patients © IFIC:2008 Techniques for Washing and Decontamination Fingernails, nail polish and artificial nails Nails must be kept short and clean Chipped nail polish support adhesion of microorganisms Artificial nails implicated in outbreaks and should be avoided Jewelry Rings, bracelets and wrist watches may not be worn Skin underneath jewelry and watches more heavily colonised Impossible to clean skin adequately when covered by jewelry Rings and watches make donning gloves difficult © IFIC:2008 Washing and Decontamination Gloves Use for the chosen task Remove immediately after task Reduce the risk of transmission of HAI from the hands of personnel by 70-80 % Protects HCWs hands from patient’s flora and infectious body fluids Do not provide total protection or replace hand hygiene Microorganisms can contaminate the HCWs hands via small defects in the gloves or during glove removal Hand hygiene always must occur after glove removal © IFIC:2008 Hand Hygiene Technique Soap and water Rub – covering all surfaces of hands and fingers Rinse with water Dry with disposable towel Use towel to turn off faucet © IFIC:2008 Hand Hygiene Technique Alcohol-based hand rub Apply sufficient volume to the palm of one hand and rub hands together Cover all surfaces and fingers, rub until hands are dry Covering the whole surface of the hands is important © IFIC:2008 Improving Compliance Have a clear written policy Should be followed by all HCWs Easy access to hand hygiene facilities On-going promotion campaigns to increase awareness of all staff including the executive level Monitor technique and provide performance feedback Careful selection of products Staff will not use products damaging to their skin or difficult to use © IFIC:2008 Basic Recommendations If hands not visibly soiled, use an alcohol-based hand rub for routine antisepsis Wash hands before starting work, entering the operating room, eating, after using a restroom and when hands are visibly soiled Keep nails shorts and clean Do not wear artificial fingernails, nail polish or jewelry Do not wash or disinfect gloves between uses on different patients © IFIC:2008 Basic Recommendations Multiple-use cloth towels not recommended Liquid soaps in dispensers preferred Do not add soap to a partially empty liquid soap dispenser Hand hygiene products should have low irritancy Ask personnel for input regarding the tolerance of any products For surgical scrub - preferably use an alcoholbased hand rub © IFIC:2008 Basic Recommendations Use hand lotions frequently to minimize irritant contact dermatitis Encourage personnel to report any adverse event related to a hand hygiene product to the infection control person and to the Occupational Health Department © IFIC:2008 Surgical Hand-Scrub When using an alcohol-based product, pre-wash with soap once a day before starting surgery and when hands are soiled (glove perforation) or sweaty Brushes are not necessary and can be a source of contamination Hand washing immediately prior to every rub does not improve its efficacy Scrub for 1-5 minutes according to the manufacturer’s recommendation After application, rub till hands are dry © IFIC:2008 Improving Hand Hygiene Educate personnel continuously Administrative support and financial resources Readily available alcohol-based hand rub Provide HCWs with alcohol-based handrub in individual pocket-sized containers © IFIC:2008 Improving Hand Hygiene Provide HCWs with hand lotions or creams especially in critical areas Provide diagrams on how to use a rub Monitor HCWs' adherence with local recommendations and provide feedback Evaluate adherence to hand hygiene using a performance indicator © IFIC:2008 Key Points Hand hygiene is the most important way to prevent HAIs Long nails, polish, rings, bracelets and wrist watches should not be worn All personnel should follow hand hygiene guidelines Alcoholic hand rub is a safe method to reduce skin flora © IFIC:2008 Key Points Alcoholic hand rub can replace handwashing and surgical scrub if hands are not visibly soiled Gloves should only be worn for specific tasks Continuous education and regular audits can improve hand hygiene compliance © IFIC:2008 References and Further Reading Centers for Disease Control and Prevention (CDC).
