gloves do not replace hand hygiene

After touching your face or hair

After using the rest room – must use soap
and water!

Standard Precautions – Surface Disinfection


When to Clean Equipment:

Wipe down re-useable equipment after each
patient use

Clean High touch objects daily such as

What to Use:

Germicidal wipe such as CaviWipes. Alert: be
sure to wear gloves with use.

Infection Prevention
Standard Precautions – Injection Safety
Injection Safety Guidelines From CDC

Never administer medications from the same syringe to
more than one patient, even if the needle is changed.

After a syringe or needle has been used to enter or connect
to a patient’s IV it is contaminated and should not be used
on another patient or to enter a medication vial.

Never enter a vial with a used syringe or needle.

Do not use medications packaged as single-dose vials for
more than one patient.

Assign medications packaged as multi-dose vials to a single
patient whenever possible.

Do not use bags or bottles of intravenous solution as a
common source of supply for more than one patient.

Follow proper infection control practices during the
preparation and administration of injected medications.
Infection Prevention
Hospital Influenza Plan – Your Role
1.
Use respiratory etiquette education (Cough
and/or sneeze into your sleeve)
2.
Practice Hand Hygiene.
3.
Get Influenza vaccinations for seasonal flu
(October to March)

Vaccinated students must wear colored
plastic tag identifier.

Unvaccinated staff:

Sign a Declination form as required by
state law and Cal/OSHA

During flu season (October to March),
wear a surgical mask if within six feet
of a patient .
Infection Prevention
Hospital Influenza Plan – Your Role
Stay Home if Sick:

Vomiting

Diarrhea related to
Gastroenteritis

Sore throat with fever

Fever of 100 or higher and
cough

Draining wound and/or open
wound infection for staff that
provide direct patient care
Section 2
TRANSMISSION-BASED
PRECAUTIONS
Infection Prevention
Transmission Based Precautions
Personal Protective
Equipment
 Health care workers wear PPE in patient’s
room
 Patient wears PPE when outside the room
 Staff and volunteers are NOT to wear PPE
(including gloves) in the hallway unless
providing critical care during transport
 Tie BOTH neck and waist ties on the gown
 PPE is disposed in regular trash unless
grossly contaminated with a patient’s body
fluids
Wrong!
Infection Prevention
Transmission Based Precautions
How to Put
On PPE
Alert:
Both neck and
waist of gown
must be tied.
Infection Prevention
Transmission Based Precautions
How to
Remove PPE
Alert:
Do NOT Wear
PPE outside
the Patient
Room
Infection Prevention
Transmission Based Precautions
Contact Precautions:
(example diseases: MRSA, VRE,
Scabies, Lice)

Wear Personal Protective
Equipment: gloves, gowns upon
entry to patient room; remove before
leaving the room: PPE NOT required
in arc of the door
Infection Prevention
Transmission Based Precautions
Droplet Precautions:
(example diseases: Influenza,
Bacterial Meningitis)

Wear Personal Protective
Equipment: mask upon entry to
patient room; remove before leaving
the room

N95 or PAPR for high hazard
procedures
N95 Mask
PAPR
Infection Prevention
Transmission Based Precautions
Airborne Precautions:
(example diseases: TB, Novel or
Unknown Disease)

Wear Personal Protective Equipment:

N95 mask- must be fit tested

PAPR* for high hazard procedures
such as Bronchoscopy, suctioning,
SVN etc.
* PAPR = Powered Air Purifying Respirator
N95 Mask
PAPR
Infection Prevention
Other Measures
 No food or drink in patient care areas (includes
nurses’ station)
 Food and drink items must be covered when carried
through hospital hallways
 Hand hygiene before entering a patient room every
time
 Educate patients, family, and visitors about hand
hygiene (entering and exiting)
 Clean up! – examples: wrappers on floor, spilled
beverages in pantry
Infection Prevention

Infection Prevention
Communicable Diseases
Superbugs” live on surfaces…also known as Multidrug Resistant
Organisms (MDROs). Note the survival rates for each.

MRSA Survival (Methacillin

Resistant Staph Aureus)


Formica surfaces = 14 days

S. aureus (MRSA) can remain
virulent and capable of causing an
infection for 10 days after
exposure to dry surfaces
VRE Survival (Vancomycin Resistant
ESBL – Extended Spectrum Beta
Lactamase


Clostridium Difficile
Survival (Not a MDRO but “Other Organism
of Concern”)



About Pulmonary tuberculosis (TB)

A contagious bacterial infection that mainly
involves the lungs. State of California has a high
incidence

Annual testing (TB skin Test) for exposure is
required
Student are not allowed to provide
care of patients in Airborne Isolation
Precautions.
