Hand Hygiene and Health Care-Associated Infections
Clint Pollack, MD, Quality Director
Children’s Hospital Central California
The impact of HCAI
HCAI can cause:
■ more serious illness
■ prolongation of stay in a health-care facility
■ long-term disability
■ excess deaths
■ high additional financial burden
■ high personal costs on patients and their families

LACK OF HAND
HYGIENE
Prevention of HCAI
■ At least 50% of HCAI could be prevented!
■ Most solutions are simple and not resource-demanding
Hand transmission
■ Hands are the most common vehicle to transmit health care-associated pathogens
The 5 Moments for Hand Hygiene
How to clean your hands
■ Handrubbing with alcohol-based handrub is the preferred routine method of hand hygiene if handsare not visibly soiled
■ Handwashing with soap and water – essential when when hands are visibly dirty or visibly soiled (following visible exposure to body fluids)1
1 If exposure to spore forming organisms e.g. Clostridium difficile is strongly suspected or proven, including during outbreaks – clean hands using soap and water
To effectively reduce the
growth of germs on hands,
handrubbing must be
performed by following all of
the illustrated steps.
This takes only 20–30
seconds!
How to handrub
How to handwash
To effectively reduce the
growth of germs on hands,
handwashing
must last 40–60 seconds
and should be performed by
following all of the illustrated
steps.
Hand hygiene and glove use
■ The use of gloves does not replace the need to clean your hands!
Adequate handwashing with water and soap requires 40–60 seconds
Average time usually adopted by health-care workers: <10 seconds
Alcohol-based handrubbing: 20–30 seconds
Time constraint = major obstacle for hand hygiene
Pop-QuizWhat are the 5 moments for hand hygiene?
1. Before touching a patient
2. After touching a patient
3. Before a procedure
4. After a body-fluid exposure risk
5. After touching patient surroundings
Summary
■ HCAI places a serious disease burden and significant economic impact on patients and health-care systems
■ Appropriate hand hygiene – the simple task of cleaning hands at the right times and in the right way – saves lives
■ There are 5 indications (moments) for hand hygiene in health care
■ Global compliance with the “My 5 Moments for Hand Hygiene” approach is universally sub-optimal
■ CHCC has implemented an action plan to improve hand hygiene and reduce infection
■ Your support and compliance with the initiatives is essential to save lives in our facility
