2
Pretest (True or False)
  • Influenza is easily spread by touching
    contaminated door knobs
  • Vaccine always prevents influenza
  • You can get influenza from vaccine
  • Influenza vaccine is made from influenza virus
    grown in live chicken eggs
  • Influenza can be prevented by wearing a mask
  • The Avian flu pandemic will spread to us in the
    next year or two

3
Objectives
  • Understand
  • how influenza spreads
  • the consequences of influenza
  • Learn how to
  • Keep from getting influenza
  • How to reduce influenza transmissibility
  • About outbreak control strategies
  • Pandemic influenza, and how to prepare as part of
    infection control in long-term care settings

4
Influenza is a Contagious Disease
  • Influenza occurs normally in aquatic birds
  • Waterfowl are the natural reservoir
  • Epidemic and pandemic influenza must spread from
    person to person
  • Influenza is spread by droplet aerosol
  • Coughing and sneezing are the most efficient way
    to spread influenza

5
Wartime and Influenza 1918
  • Grouping people close together
  • For extended periods
  • Whether sick or well
  • Global travel
  • PANDEMICS

6
Influenza Transmission
  • Depends on
  • hang time
  • Amount of virus in each droplet
  • Number of droplets inhaled
  • Immunity in person inhaling infected droplets
  • Number of droplets inhaled relates to distance
    from source of infected person coughing or
    sneezing
  • Clothing, bedding, hands, knobs make inefficient
    sources for influenza transmission

7
Influenza in LTC
  • We looked at 104 cases of influenza in a large
    LTC facility. Attack rate was
  • 18 overall
  • 14 in those living in rooms alone
  • 21 in those paired, but only one was able to
    leave on their own
  • 35 in those paired but both stuck there
  • 75 in those paired, married, living in the same
    room
  • Limit spread by spacing ill from not ill
  • 6 feet or more would be ideal

8
Wheres Influenza in LTC from?
  • STAFF
  • Most staff are not vaccinated (
  • Almost all residents are (90)
  • Most resident cases get infected by staff
  • Best and most cost-effective approach to reduce
    influenza in nursing homes is to vaccinate staff
    (more than 80 to make this work reliably)
  • Visitors
  • Can also bring in influenza. Less than 10
    vaccinated
  • Reduce visitors during influenza season

9
Policies for Influenza Reduction
  • Before influenza arrives Vaccination
  • Vaccinate staff (aim for 80)
  • Those with direct patient contact and children
    are the highest priority
  • Those with children will likely get influenza
    from their children
  • Vaccinate residents (aim for 97)
  • Offer vaccine for frequent visitors (sitters,
    family, temps)
  • Once Influenza is there change environmental
  • Vaccinate? And STEP UP SURVEILLANCE
  • Reduce group activities and mixing between wards
  • Separate ill from not ill screen visitors
  • Send ill staff home for at least a week unless
    getting antiviral (treat with Tamiflu or Relenza
    for five days)
  • Antivirals (chemoprophylaxis exposed residents)

10
DIAGNOSIS Is it a cold or the FLU?
11
Influenza The Way To Think About It
12
Cytokine response
  • Influenza infection is localized within the
    respiratory tract, but the release of cytokines
    produces a systemic response
  • Systemic symptoms caused by cytokines include
    myalgia, malaise, and fever
  • People with less cytokine are less symptomatic
  • Old people produce less cytokine
  • Old people have fewer symptoms
  • Less fever
  • Less myalgia

13
Vaccination, even poor match, reduces fever
(inflammation)

Zanamivir vs. rimantadineDistribution of
Influenza Cases
16
Influenza Treatments
  • Adamantanes, rimantadine (Fluvirin, ) and
    amantadine (Symmetrel, )
  • Effective against influenza A, but not B, and not
    in 2006!
  • Resistance develops rapidly
  • Zanamivir (Relenza, inhaled, ) and oseltamivir
    (Tamiflu, ) are neuraminidase inhibitors,
  • Effective against influenza A and B
  • Resistance is rare (.3 in Japan for oseltamivir
    0 as of yet for zanamivir)
  • All treatments begin in 48 hours of onset, for 5
    days, twice daily (less for renal insufficiency
    except zanamivir)
  • Chemoprophylaxis is
  • half the dose for 10 to 14 days (7 days past the
    last new case in the building)

17
Other approaches
  • Hand washing
  • Covering your mouth
  • The Artic Hut experiment
  • Facial tissues
  • Antiviral facial tissues
  • Masks for general use
  • Cough into sleeve, not hand
  • Segregation
  • The roommate story
  • Hang time
  • Doors as barriers
  • Surfaces steel, Formica and pillow cases

Pandemic What to Anticipate
  • No idea!
  • Dont know when it will arrive, only that it will
  • Dont know the severity
  • Might be mild, seasonal epidemic (Category 1)
  • Might be severe, Spanish Flu (Category 4 or 5)
  • 1-3 million dead, 20-50 of population ill
  • Society would shut down food delivery, utilities
    and telephone, grocery stores, schools,
    transportation, etc. likely for many weeks (12?)
    staff home sick!
  • If it occurs in the next year or two, there will
    be a scramble for vaccine
  • LTC residents and staff likely low on the
    priority list

21
Strategic National Stockpile Goals
HHS stockpile contains 4 million doses against
A/H5N1/Vietnam-2004 strain First FDA A/H5 vaccine
approved 4/17/07, for ages 18-64 years of
age Federal stockpile already has 31 million
courses stockpile enough for 25 of US Source
Adapted from HHS Pandemic Planning Update II
6/26/06 Implementation Plan for the National
Strategy for Pandemic Influenza
22
Pandemic Influenza Special Considerations
  • Pandemic influenza, when it arrives will it has
    the potential to be the equivalent of a
    long-lasting disaster (think hurricane, but for
    2-3 months)
  • Disaster preparedness plans is an appropriate
    context for LTC facilities
  • Water, canned foods, hygiene and cleaning
    supplies, infection control supplies,
    incontinence products, blankets, sleeping bags,
    tents, battery-operated radio and lanterns,
    flashlights, body bags
  • Consider storage for stockpile, pharmacy

23
How to Plan
  • Consider what would be essential if no supplier
    is available for critical services for 6-8 weeks
  • Think incrementally--the first two weeks then
    for four weeks, etc.
  • Part of an all-hazards disaster plan
  • Infection control, staffing, communications,
    supply lines
  • Internal assessment of current preparedness
  • Staff knowledge
  • Infection control and airborne disease, vendor
    agreements, other critical operations (e.g.,
    food, pharmacy)
  • How would staff function with 40 absenteeism?

24
How to Plan What about?
  • Hands-on care
  • Incontinence, transfers, repositioning, feeding
  • Contingency for volunteers (family, retired,
    community, non-clinical, housekeepers, sales)
  • Pilot concept locally
  • Training materials for new staff roles videos,
    manuals
  • Determine sources, gather

25
How to Plan What about?
  • Absenteeism 30-40?
  • Due to employee illness, family illness, school
    closures and child care, fear of workplace
    infection
  • Prioritize care by acuity and resident self-help
  • Onsite housing for staff and family?
  • Hands-on care
  • Incontinence, transfers, repositioning, feeding
  • Contingency for volunteers (family, retired,
    community, non-clinical, housekeepers, sales)
  • Pilot concept locally
  • Training materials for new staff roles videos,
    manuals
  • Determine sources, gather
  • Develop regulatory exceptions at state and
    federal levels

26
How to Plan What about?
  • Medications
  • Can doses be skipped or drugs held?
  • triage plan for high and low priority medicines
    by resident, sharing medications,
    physician/pharmacy advice access (to extend
  • Develop regulatory exceptions at state and
    federal levels
  • Scope of practice, documentation
  • Antiviral priorities
  • Staff vs. residents (utilitarian vs. libertarian
    ethics)
  • Vaccine priorities
  • Who gets first incoming doses
  • Refrigeration, expiration dates
  • Needles, syringes and similar supplies

27
First Steps
  • Check out
  • http//pandemicflu.gov/plan/healthcare/longtermcar
    echecklist.html
  • 24 major planning steps, with 54 subordinate
    tasks
  • HCANJ, AHCA, OHCA efforts and recommendations
  • Multidisciplinary team/planning committee to
    address disaster and pandemic planning
  • Develop contacts with local, regional and state
    emergency preparedness groups, including
    bioterrorism/communicable disease coordinators
  • Areas hospital contacts to strategize
    hospitalization and facility resource sharing
  • Develop a written pandemic influenza plan,
    incorporating local/regional/state plans

www.hhs.gov/pandemicflu/plan/
28
Steps Pandemic Plan Elements
  • Surveillance residents, staff, visitors
  • Communications
  • Education personnel, residents, family members
  • Infection control for managing residents, staff
    and visitors with pandemic influenza
  • Occupational health for dealing with staff
    absences and other issues
  • Vaccine and antiviral use
  • Surge capacity

wws/hhs.gov/pandemicflu/plan/sup10.html
29
Surge Capacity
  • Contingency staffing (prioritizing critical from
    non-essential services by resident health status,
    functional limitations, disabilities and
    essential facility operations)
  • Estimate how many supplies needed in stockpile
    (masks, gloves, hand hygiene, IV pumps, etc.)
  • Address likely supply shortages, and alternative
    channels for procuring needed resources.
  • Strategies to help increase hospital bed capacity
    in community
  • Managing need for post mortem care, disposition
    of deceased
  • Area in facility that might be used as a
    temporary morgue

30
Participate!
  • If LTC is not represented at the planning steps
    for the community, others will make the decisions
  • How to handle quarantine
  • Where to send supplies, food and how much
  • How to allocate beds and services
  • How to reallocate staff
  • Dont wait to be contacted engage
  • Reach across state lines
  • Let law enforcement know

Summary of the Community Mitigation Strategy by
Pandemic Severity
http//www.pandemicflu.gov/plan/community/commitig
ation.html
32
Posttest (True or False)
  • Influenza is spread by small droplet aerosol
  • Epidemic and pandemic influenza is spread from
    person-to-person
  • Vaccines really dont work, can give you the
    flu!
  • My doctor can look down my throat and diagnose
    (or exclude) influenza just by looking!
  • Influenza always causes a cough/sneeze and a
    fever
  • Tamiflu and Relenza can treat influenza if it is
    started within the first 2 days of symptom onset
  • Separating residents for meals and activities can
    reduce spread of influenza between them
  • Pandemic planning includes training outside of
    scope of practice

33
Summary
  • Influenza causes respiratory disease
  • Influenza is spread between people via air
  • Separating ill people from others reduces spread
  • Influenza is contagious from a few days (in
    young) to up to a week or more (in old)
  • Vaccination can prevent influenza or reduce
    symptoms from influenza
  • Vaccinated people spread influenza to others less
    easily because they dont make as much virus, and
    dont cough and sneeze
  • Pandemic planning is important locally, and
    should be part of larger disaster preparedness

Please, Lord, enough already!
