Hand Hygiene
Janet Weber, RDH, MEd
Why Is Hand Hygiene Important?

Hands are the most common mode of
pathogen transmission



Hand washing is an extremely important step in
overall infection control
Hand washing significantly removes the bacterial
flora on the skin
Hand washing protects you and your patient from
the bacterial flora (from each other) from
becoming skin residents

HAND WASHING BEFORE
AND AFTER CONTACT
WITH EACH PATIENT IS THE
SINGLE MOST IMPORTANT
MEANS OF PREVENTING
THE SPREAD OF
INFECTION



Hands should be washed with hand soap OR
Alcohol base rubs may be used if hands are not visibly soiled.
Studies show that using an alcohol rub for a minimum of 10
seconds can be more effective in removing the bacterial flora
on the hands than hand washing.
Antibacterial hand soaps are not necessarily recommended
due the drying effect it has on the skin when used frequently.
Cracking (open surface) can lead to surface infections on the
hands.
Hand Hygiene Definitions:
Hand washing
Washing hands with plain soap and water

Antiseptic hand wash
Washing hands with water and soap or other detergents containing
an antiseptic agent

Alcohol-based hand rub
Rubbing hands with an alcohol-containing preparation (used after
hand washing)

Surgical antisepsis
Hand washing with antiseptic soap or alcohol-based handrub
before operations by surgical personnel (Antiseptic preparations
for surgical hand hygiene should have persistent (long-lasting)
antimicrobial activity)
When to Wash:



Visibly dirty
After touching contaminated objects with
bare hands
Before and after patient treatment
(before glove placement and after glove
removal)
 Optional use of alcohol based hand
rub is acceptable if hands are not
visibly soiled
Hand washing before and after contact with each
patient is the single most important hygiene
measure for reducing or preventing the spread of
infection
Rings and Jewelry

Hand jewelry should not be worn as
it may tear gloves and harbor
bacteria

Studies have demonstrated that skin
underneath rings is more heavily
colonized than comparable areas of
skin on fingers without rings
 the
more rings worn, the greater
concentration of organisms
Studies have demonstrated that skin underneath
rings is more heavily colonized than comparable
areas of skin on fingers without rings. The more
rings worn, the greater concentration of
organisms
Fingernails



Can affect the integrity of gloves
Can also harbor bacteria
Keep fingernails SHORT!
Avoid artificial nails
 Avoid chipped nail polish

Technique

Initial scrub- 30 seconds

Interlace fingers during scrub

Create friction while washing
Hand washing
Initially (when first preparing
for the clinic session)- hands must
be washed with antiseptic hand
wash for a minimum of 30 seconds.
 It is extremely important at this time to focus on
technique!

 Interlace
fingers
 Clean under nails and around cuticles
Hand Hygiene Technique Routine Dental
Procedures

Hand washing
 Wet
hands with cool or lukewarm water, apply soap, rub
hands together for at least 15 seconds
 Rinse and dry with disposable towel
 Use towel to turn off faucet

Hand rubs
 Apply
to palm of one hand, rub hands
together covering all surfaces until dry
 Volume:
 Based
on manufacturer’s instructions
Guideline for Hand Hygiene in Health-care Settings. MMWR 2002; vol. 51, no. RR-16.
Technique (continued)



Be sure not to touch ANYTHING after washing
Watch, when rinsing, that rinse water does not
touch non clean areas and then contaminate the
clean area
Dry hands thoroughly to prevent drying and
cracking
Wash hands (or use and alcohol based rub)
before glove placement and after glove
removal.

Hand Protection
Gloves
 Minimize
the risk of acquiring infections from patients
 Prevent
microbial flora from being transmitted from
dental health care providers to patients
 Reduce
contamination of the hands of dental health
providers by microbial flora that can be transmitted from
patient to patient
 Are
not a substitute for hand washing!
Latex Hypersensitivity

Mild to Moderate
 Contact
Dermatitis – Localized Rash
 Non
Allergic type – Skin Dry & Itchy
 Allergic Type IV: Delayed reactionappears over time 12-48 hrs

Moderate to Severe Hypersensitivity
 Allergic
Type I
 Immediate
hypersensitivity – may include runny
nose, itchy eyes, hives, ‘burning’ skin
 Severe reactions effect respiratory system
Irritant Contact Dermatitis:
Irritant Contact Dermatitis: Most common reaction to latex products. Dry,
itchy, irritated areas on the skin, usually the hands. Not a true allergy.
Allergic Contact Dermatitis:
Results from exposure
to chemicals added to
latex during
harvesting, processing
or manufacturing.
Rash usually begins
24- 48 hours after
contact and may
progress to oozing
skin blisters.
Latex allergy can be
acquired over time.
Latex Allergy (Type 1 or immediate):
The most
serious of
the reactions
that usually
begins within
minutes of
exposure to
latex, can
occur hours
later with a
variety of
symptoms.
Incidence of latex reaction
In Summary:


Hand washing

Wet hands with cool or lukewarm water, apply soap, rub
hands together for at least 15 seconds

Rinse and dry with disposable towel

Use towel to turn off faucet
Hand rubs

Apply to palm of one hand, rub hands
together covering all surfaces until dry

Volume:
 Based
on manufacturer’s instructions

Wear gloves when contacting blood, saliva, and
mucous membranes

Remove gloves immediately torn, cut or punctured

Remove gloves after patient care

Do not wash, disinfect or sterilize
gloves for reuse
Recommendations for Gloving:

Wear gloves when contact with blood, saliva, and mucous
membranes is possible

Remove gloves immediately that are torn, cut or punctured

Remove gloves after patient care

Do not wash, disinfect or sterilize gloves for reuse
Types of Procedural Gloves”
Patient Procedure
Surgical
Housekeeping
Housekeeping
Gloves
Look closely at the gloves
you choose!
Vinyl gloves used to clean
the operatory look very
similar to the latex gloves.
It is hard to tell the
difference between them.
(Vinyl is thicker to the feel).
Types of Patient Procedure Gloves:
Nitril
Latex
A Balancing Act: Which to choose?
Glove Fit:




Should be available in
a variety of sizes and
types
May causes hand
fatigue if gloves don’t
fit correctly
Glove integrity may be
compromised
Injury is more likely to
occur do to an ill fitting
glove
Example of Gloves that are too TIGHT
Will cause fatigue as fingers try to flex
Pulls too tightly across the palm.
Will cause fatigue at thumb joint.
Example of Gloves that are too LOOSE
Gloves that are too large pose a danger as excess
glove material can catch on something and tear.
Tactile sensitivity during procedures is greatly
reduced as well.
Example of Gloves that are JUST RIGHT!
