Chain of Infection
Chain of Infection
Becoming Infected Depends on 3 Variables
• Condition or health of susceptible host
• Virulence (strength) of the germ
• Amount of inoculum – how much did you
get?
Breaking the Chain: OSHA
• OSHA = Occupational Safety and Health
Administration
• Purpose: Regulate employers so your
workplace is SAFE
– Bloodborne Pathogen Standard
• GHS
– Exposure Control Plan
– Exposure Category I, II, III

– Any disease-producing
– Vaginal secretions
microorganism (germ) in
– Semen
the form of viruses or
– Wound Exudate
bacteria.

Peritoneal fluid
Synovial fluid
Any body fluid with visible blood

Modes of Transmission
Modes of Transmission:
Vector & Common Vehicle
• Vector
– Carried by plant or animal
• Common Vehicle
– Common carrier for the
germs, such as people, food,
animals, and contaminated
instruments
Modes of Transmission:
Contact
• Direct Contact
– Person-to-person spread
– Actual physical contact between source &
susceptible host
• Indirect Contact
– Susceptible host comes in contact
contaminated object
– Germ that is spread is on the item and
comes in contact with susceptible host
Modes of Transmission:
Contact
• Diseases spread by contact
– Antibiotic-resistant organisms
• MRSA
• VRE
• Pediculosis (lice)
• Scabies
Modes of Transmission:
Contact
• Private Room
• Gloves
• Gowns
• Use dedicated equipment
OR clean equipment
before leaving the room
Modes of Transmission:
Contact
• MUST wash your hands
with SOAP & WATER
• Private Room
• Gloves
• Gowns
• Use dedicated equipment
OR clean equipment
before leaving the room
Modes of Transmission:
Contact
X represents VRE culture positive sites
~ Contaminated surfaces increase cross-transmission ~
Abstract: The Risk of Hand and Glove Contamination after Contact with a
VRE (+) Patient Environment. Hayden M, ICAAC, 2001, Chicago, IL.
Modes of Transmission:
Contact
Transportation of the Patient
• Place a clean gown on the patient
• Use clean linens to cover patient / stretcher for
•
•
•
transport
Ensure all drainage is contained
Assist patient to perform hand hygiene
Wear gloves and gowns as indicated to assist
the patient onto a stretcher or wheelchair
If you are assisting with the transport of the patient, after you have moved the
patient to the stretcher, remove your PPE and clean your hands before leaving the
room.
Modes of Transmission:
Contact
Transportation of the Patient
• Additional steps are required if drainage can
NOT be contained
– 2 persons are required to transport the patient
– The one who has contact with the patient/bed may
wear PPE
– The other person is to open doors, push elevator
buttons and does NOT wear PPE
Modes of Transmission:
Droplet
• Large particles that rapidly settle out on flat
surfaces, like tables or trays
• Germs travel quickly through air (3 ft or less)
• Transmission involves contact with your eyes,
nose, or mouth
Modes of Transmission:
Droplet
• Disease spread by droplets
– Diphtheria
– Bacterial meningitis
– Mumps
– Rubella
Modes of Transmission:
Droplet
• Private Room
• Facial Protection
within 3 feet of the
patient
Modes of Transmission:
Airborne
• Contained within droplet or dust particles
• Suspended in air for extended period
– May spread through air ducts
• May involve varying distances between source
and susceptible host
Modes of Transmission:
Airborne
• Disease Spread by Airborne transmission
– Pulmonary tuberculosis
– Measles
Modes of Transmission:
Airborne
• Negative Pressure
Private Room
• N95 respirator or
PAPR hood
• Keep door closed at
ALL times
Pulmonary Tuberculosis
• Caused by Mycobacterium tuberculosis
• Symptoms:
–
–
–
–
–
–
–
Fatigue
Fever
Lethargy
Weakness
Night sweats
Weight loss
Persistent productive cough
Pulmonary Tuberculosis
• Outpatients presenting with cough
– Assess patient for symptoms
– If patient has cough & 2 or more symptoms:
• Immediately mask the patient
• Place in negative pressure room (if available) or private
room with the door closed
• If patient leaves the room, he needs to wear a mask
• MD to assess ASAP
– If MD suspects pulmonary TB:
• Notify Admitting Office to locate negative pressure room
• Patient wear mask during transport
• Inpatients assessed to have signs & symptoms of TB
– Place patient on Airborne Precautions
– Notify Infection Prevention Department
Modes of Transmission:
Multiple
• There are multiple diseases that can be
spread by more than one route of
transmission
– Pertussis (contact & droplet)
– RSV (contact & droplet)
– Chicken pox / disseminated herpes zoster
(contact & airborne)
Modes of Transmission:
Multiple
• Follow the sign for
correct PPE usage
• Clean your hands
BEFORE and AFTER
the removal of PPE
Break the Chain:
Communication of Expanded Precautions
• Initiating Expanded Precautions
– RN’s
– MD’s
– Infection Prevention Team
• If someone other than Infection Prevention
initiates precautions, they need to call the
Infection Prevention Department
Break the Chain:
Communication of Expanded Precautions
• Nursing Responsibilities
– Sign on door
– Sticker on front of chart
– Sticker in MD progress notes
• Include organism and site
– Educate patient/family
– Document patient/family education
– Document precautions every 24 hours
Break the Chain:
Communication of Expanded Precautions
• Discontinuing Precautions
– ONLY done by the Infection Prevention Team
– If an MD writes an order to discontinue
precautions, Infection Prevention MUST be
consulted to determine if precautions can be
discontinued
Continuum of Care
(Related to Antibiotic Resistance)
• The type of precautions required and extent of
the level of care a patient receives changes as
they move through the healthcare system
Ambulatory Care /
Physician Practice /
Outpatient Treatment
Acute Care
Long Term Care /
Subacute /
Rehab /
Home Care
Continuum of Care
(Related to Antibiotic Resistance)
Patient’s risk of contact transmission changes
related to:
•
•
•
•
Number of invasive devices
Activity level
Bowel/bladder control
Existence of body fluid drainage
Continuum of Care
(Related to Antibiotic Resistance)
• The level of precautions needed for a patient will
change related to the varying levels of risk

Standard Precautions
Break the Chain:
Standard Precautions
GHS considers all blood, body substances and nonintact skin potentially infectious.
To minimize exposure follow:
• Work practice controls
– Hand hygiene
• Engineering controls
– PPE
These Controls and Barriers are STANDARD
PRECAUTIONS and are practiced AT ALL TIMES for
ALL PATIENTS and in ALL SITUATIONS.
Break the Chain:
Standard Precautions
• Treat every patient as if infectious.
• Wear Barriers appropriate for care being given.
For Example:
– Wear gloves when likely to touch body substances,
mucous membranes or non-intact skin.
– Wear gown when clothing is likely to become
soiled.
– Wear facial protection when likely to be splashed
with body fluids.
Break the Chain:
Standard Precautions
• Not sure what PPE is required for a
procedure in order to protect yourself?
– Section 8 of the Infection Prevention Manual
has a table that lists minimum requirements of
PPE
– The list is not all-inclusive, so use
professional judgment to assess the need for
additional barrier precautions

Break the Chain:
Hand Hygiene
• How?

all over surfaces
of both hands
and allow to dry.
Break the Chain:
Hand Hygiene
When MUST you wash your hands with
soap and water?
• When your hands are visibly soiled
• When your hands are visibly contaminated
with blood and body fluids
• Before eating
• After using the restroom
• If the patient has a spore forming bacteria
such as C. difficile or Anthrax
Break the Chain:
Hand Hygiene
When CAN you use an alcohol-based hand
rub?

• AFTER having direct contact with a patient or the
patient’s skin
• AFTER having contact with body fluids, wounds, or
broken skin if your hands are NOT visibly soiled
• AFTER touching equipment or furniture near the
patient
• BEFORE and AFTER removing gloves

Infectious Waste
Classification of infectious waste and
recommendations for proper handling are found in
Section 8 of the Infection Prevention Manual
– Expanded precautions patients
• Waste from room of a patient in expanded precautions is handled
the same as for ALL patients
– Reusable Equipment / Trays
• DO NOT place reusable equipment/trays in red biohazard bags
• Use clear biohazard labeled bags
– Linen
• All linen is considered infectious
Break the Chain:
Infectious Waste
• Management of spills
– Follow procedure for management of spills found in
Section 8 of the Infection Prevention Manual
– Follow standard precautions when managing spills of
blood/body fluid
– Spill kits are available in the Omnicell and soiled utility
rooms
– Use shovel/scrapper if sharp objects. Use disposable
towels to clean up. Dispose of in biohazard container.
