Hand hygiene in health care:
● Nurses move patient to patient and room to room while providing care and
working in a patient care environment. This movement provides
opportunities for the transmission of organisms on hand.
Hand hygiene:
● Most effective way to prevent spread of organisms
● Transient VS resident microbes
● Transient: just passing through. Unable to remain in the body for extended
period of time
● Resident: the “residents”. Life-long member of the body’s normal microbial
community
● Hand hygiene w/ alcohol- based hand rub kills organisms in seconds
● Hand hygiene w/ soap and water removes organisms
2 Methods:
● Alcohol- based hand rub is the preferred method for cleaning hands. It’s
better than washing hands. (when hands are not visibly soiled)
● Handwashing w/ soap and water must be done when hands are visibly soiled
● Clean hands for a minimum of 15 seconds
When to perform hand hygiene?
● Before preparing, handling, serving or eating food
● After personal body functions
● Before putting on and after taking off gloves
4 Moments for hand hygiene:
1. Before initial patient/ patient environment contact

● Mode of transmission
○ How the pathogen travels
○ contact/ droplet/ airborne
