so why all the fuss about hand hygiene
So Why All the Fuss About Hand Hygiene?
  • Most common mode of transmission of pathogens is via hands!
  • Infections acquired in healthcare
  • Spread of antimicrobial resistance

CDC

nosocomial infections
Nosocomial Infections
  • 2 million/year in US
  • 80,000 deaths/yr (IHI)
  • Heavy colonization of patients
    • Intact skin as well
    • Environmental surfaces
      • 106 squames shed daily
      • Enterococcus and Staph aureus resist dessication
  • HCW hands easily contaminate even after “clean” procedures

data for efficacy of hand hygiene
Data for efficacy of hand hygiene
  • Semmelweiss et al
  • 1960s prospective, controlled trial
    • sponsored by the National Institutes of Health and the Office of the Surgeon General
    • demonstrated that infants cared for by nurses who did not wash their hands after handling an index infant colonized with S. aureus acquired the organism more often and more rapidly than did infants cared for by nurses who used hexachlorophene to clean their hands between infant contacts

factors affecting hand hygiene compliance
Factors affecting hand hygiene compliance
  • Outbreak investigations have indicated an association between infections and understaffing or overcrowding
  • association was consistently linked with poor adherence to hand hygiene.
self reported factors for poor adherence with hand hygiene
Self-Reported Factors for Poor Adherence with Hand Hygiene
  • Handwashing agents cause irritation and dryness
  • Sinks are inconveniently located/lack of sinks
  • Lack of soap and paper towels
  • Too busy/insufficient time
  • Understaffing/overcrowding
  • Patient needs take priority
  • Low risk of acquiring infection from patients

a.k.a excuses

physician compliance
Physician compliance
  • Consistently, physicians score lower than other healthcare workers
  • Robert Weinstein (ID at Rush) Ann Intern Med. 2004 Jul 6;141(1):65-6
    • “..after more than 150 years of prodding, cajoling, educating, observing and surveying physicians, hand hygiene adherence rates remain disgracefully low…
handwashing guidelines
Handwashing Guidelines
  • As early as 1961, USPHS produced videos about hand washing
    • Wash hands for 1-2 minutes before and after each patient contact.
    • Antiseptics discouraged.
  • 1975 CDC guidelines
  • 1985 CDC guidelines
  • 1988 APIC guidelines-start suggesting ABHG
  • 1995 HICPAC
  • 1996 HICPAC
handwashing guidelines1
Handwashing Guidelines
  • CDC
    • Guidelines for Hand Hygiene in Healthcare settings (2002)
    • Forms basis for PHD policies
  • WHO
    • Guidelines on Hand Hygiene for Health Care (draft)
regulation
Regulation
  • Multiple regulatory agencies have added hand hygiene to their list of goals
    • IHI
      • The 100,000 Lives Campaign
        • initiative to engage U.S. hospitals in a commitment to implement changes in care proven to improve patient care and prevent avoidable deaths (zero tolerance).
      • Endorsed by CDC, APIC, and SHEA
      • Component of the central line bundle
    • JACHO patient safety goal #7- Reduce Hospital Acquired Infections
      • Comply with CDC guidelines
      • Manage as sentinel events all identified cases of unanticipated death or major permanent loss of function associated with a health care-associated infection.
ihi campaign
IHI campaign
  • 4 components
    • Demonstrate knowledge
    • Demonstrate competence
    • Enable employees (provide equipment)
    • Monitor compliance and provide feedback
      • Random observations
      • Record % time all 3 components followed
        • Wash before
        • Wash after
        • Proper glove use
  • Goals of zero incidence
ihi tips
IHI tips
  • Empower nursing to enforce use of a central line checklist
  • Include hand hygiene as part of your checklist for central line placement.
  • Keep soap/alcohol-based handwashing dispensers prominently placed and make universal precautions equipment, such as gloves, only available near hand sanitation equipment.
  • Post signs at the entry and exits to the patient room as reminders.
  • Initiate a campaign using posters including photos of celebrated hospital doctors/employees recommending handwashing.
  • Create an environment where reminding each other about handwashing is encouraged.
jcaho speak up
JCAHO Speak up
  • Speak up if you have questions or concerns, and if you don't understand, ask again. It's your body and you have a right to know.
  • Pay attention to the care you are receiving. Make sure you're getting the right treatments and medications by the right health care professionals. Don't assume anything.
  • Educate yourself about your diagnosis, the medical tests you are undergoing, and your treatment plan.
  • Ask a trusted family member or friend to be your advocate.
  • Know what medications you take and why you take them. Medication errors are the most common health care errors.
  • Use a hospital, clinic, surgery center, or other type of health care organization that has undergone a rigorous on-site evaluation against established state-of-the-art quality and safety standards, such as that provided by Joint Commission.
  • Participate in all decisions about your treatment. You are the center of the health care team.

partners in your care
Partners in Your Care
  • Program designed at Penn to encourage patients to speak up
  • Focus on patient, not healthcare worker
  • Studies in Europe reported 40-50% improvement in HH compliance

indications for hand hygiene
Indications for Hand Hygiene
  • If hands are not visibly soiled, use an alcohol-based handrub for routinely decontaminating hands.
  • When hands are visibly soiled, wash with non-antimicrobial or antimicrobial soap and water.

specific indications for hand hygiene
Specific Indications for Hand Hygiene
  • Before:
    • Patient contact
    • Donning gloves when inserting a CVC
    • Inserting urinary catheters, peripheral vascular catheters, or other invasive devices
  • After:
    • Contact with a patient’s skin
    • Contact with body fluids or excretions, non-intact skin, wound dressings
    • Removing gloves

Recovery of VRE from Hands and Environmental Surfaces

  • Up to 41% of healthcare worker’s hands sampled (after patient care and before hand hygiene) were positive for VRE1
  • VRE were recovered from a number of environmental surfaces in patient rooms
  • VRE survived on a countertop for up to 7 days2

fingernails and artificial nails
Fingernails and Artificial Nails
  • Natural nail tips should be kept to ¼ inch in length
  • Artificial nails should not be worn when having direct contact with high-risk patients (e.g., ICU, OR)

Avoid wearing artificial nails, keep natural nails <1/4 inch if caring for high risk patients (ICU, OR)

Edel et. al, Nursing Research 1998: 47;54-59

what about gloves
What about gloves?
  • Do increase patient protection
  • Protects HCW from BBP exposure
  • Proper use essential
    • Change between patients
    • Change between sites
  • Not a substitute for hand hygiene!
    • Micropunctures in gloves can allow contamination
    • Glove removal risks contamination
what about cdiff
What about cdiff?
  • None of the agents used in antiseptic handwash or antiseptic hand-rub preparations are reliably sporicidal against Clostridium spp. or Bacillus spp.
  • controversial
  • Current PHD policy is to use soap and water in known cdiff patients (sign on ABHG dispenser)
influence of role models and hospital design on hand hygiene of healthcare workers
Influence of Role Models and Hospital Design on Hand Hygiene of Healthcare Workers

Lankford, et al Emerg Infect Dis 2003 Feb

  • assessed the effect of medical staff role models and the number of sinks on hand-hygiene compliance before and after construction of a new hospital designed for increased access to handwashing sinks.
  • 721 hand-hygiene opportunities
  • Hand-hygiene compliance was significantly better in the old hospital (161/304; 53%) compared to the new hospital (97/417; 23.3%) (p<0.001).
  • Health-care workers in a room with a senior medical staff person or peer who did not wash hands were significantly less likely to wash their own hands (odds ratio 0.2; confidence interval 0.1 to 0.5); p<0.001).
  • health-care worker hand-hygiene compliance is influenced significantly by the behavior of other health-care workers
  • increased number of hand-washing sinks did not increase hand-hygiene compliance.

IS PRIMARY!

Protect patients…protect healthcare personnel…

promote quality healthcare!
