Hand Hygiene

OVERVIEW

  • Hand hygiene is endorsed by the WHO as the single most important element of strategies to preventing healthcare associated infection (HAI)
  • It is the responsibility of every healthcare worker (HCW)
  • The recommendations on this page are based on those of Hand Hygiene Australia

REQUIREMENTS FOR TRANSMISSION OF INFECTIOUS AGENTS BY HAND

  • Organisms are present on the patient’s skin, or have been shed onto inanimate objects immediately surrounding the patient
  • Organisms must be transferred to the hands of the HCWs
  • Organisms must be capable of surviving for at least several minutes on HCWs’ hands
  • Hand washing or hand rubbing by the HCW must be inadequate or entirely omitted, or the agent used for hand hygiene inappropriate
  • The contaminated hand or hands of the caregiver must come into direct contact with another patient or with an inanimate object that will come into direct contact with the patient

TARGETS

Hand hygiene targets prevention of the following:

  • cross-colonisation of patients
  • endogenous and exogenous infection in patients
  • infection in HCWs
  • cross-colonisation of the healthcare environment including HCWs

WHEN

The timing of hand hygiene episodes is more important than their frequency.

Hand hygiene must be performed before and after every episode of patient contact. This includes the ‘5 moments of hand hygiene’:

  • before touching a patient
  • before a procedure
  • after a procedure or body substance exposure risk
  • after touching a patient
  • after touching a patient’s surroundings

Hand Hygiene must be performed:

  • on entering the patient zone from the healthcare zone (this includes after closing the screens as they are potentially contaminated)
  • between touching the patient and touching the critical sites on the same patient (e.g. IV site and drain sites)
  • before leaving the patient zone

-> Any equipment brought into the patient zone should be cleaned before and after each patient use eg. stethoscope, BP cuff, tourniquet etc.

Hand hygiene must also be performed:

  • after removal of gloves
  • before/ after work
  • before/ after eating/ drinking
  • before/ after using a keyboard
  • after visiting an infected area
  • after toileting
  • after wiping/ blowing nose

HOW

For all routine hand hygiene practices in healthcare settings, use alcohol-based hand rubs that :

  • contain between 60% and 80% v/v ethanol or equivalent
  •  meet the requirements of the EN1500 standard (a different standard is used in North America)

If hands are visibly soiled:

  •  use soap and water

If  known or suspected Clostridium difficile and non-enveloped viruses (e.g. norovirus):

  •  use soap and water if gloves have not been worn
  • After washing, hands should be dried thoroughly with single-use towels

GLOVES

Gloves are indicated to:

  • Reduce the risk of contamination of HCWs hands with blood and other body fluids
  • Prevent the transmission of infectious microorganisms via the healthcare workers hands to the environment, to the patient, as well as from one patient to another

Wearing gloves does not replace the need for hand hygiene

  • perform hand hygiene before and after glove use

Change gloves:

  • Between episodes of care for different patients, to prevent transmission of infectious material
  • During the care of a single patient, to prevent cross-contamination of body sites
  • If the patient interaction involves touching portable computer keyboards or other mobile equipment that is transported from room to room
  • Sterile gloves must be used for surgical ANTT (‘aseptic, no touch technique’) procedures and contact with sterile sites

BARRIERS TO HAND HYGIENE

HCWs must not wear artificial nails or extenders when having direct contact with patients and natural nails should be kept short (<0.4cm long)

  • Artificial, painted and chipped nails can harbour microbes and are linked to outbreaks

Avoid the wearing of hand and wrist jewellery

  • they can be heavily colonised and are usually not removed for hand hygiene

Skin care

  • Provide HCWs with hand lotions or creams to minimise the occurrence of irritant contact dermatitis associated with hand antisepsis or hand washing
  • Provide alternative hand hygiene products for HCWs with confirmed allergies or adverse reactions to standard products used in the healthcare setting
