  • What is the comfort zone, and why extend the season?
    • Current state of influenza disease in U.S.
    • Current state of influenza vaccine supply
    • Highlights of the 2007 ACIP recommendations
    • Materials available from CDC
what is the comfort zone
What is the Comfort Zone?
  • Fallacy: Vaccination season ends after National Influenza Vaccination Week
  • The job is NOT done!
why extend the season
Why Extend the Season?
  • Burden of Influenza Disease
    • Infections – 15-60 million
    • Total deaths – 36,000
    • Total hospitalizations – 200,000
    • Pediatric deaths – 56 – 154
    • Pediatric hospitalizations 20,000

Why Extend the Season?
  • Burden of influenza disease
  • It is early in influenza season
  • There are still persons at risk for influenza complications as yet unvaccinated
  • There are still people who are at risk for transmitting influenza to others, as yet unvaccinated
at risk of influenza complications
At-Risk of Influenza Complications

Groups Recommended to Receive Vaccine:

  • Children aged 6–59 months
  • All persons aged >50 years
  • Household contacts (including children) and caregivers of infants younger than 6 months
  • Children and adolescents on long-term aspirin therapy
  • Pregnant women
  • Adults and children who have chronic diseases
  • Immunosuppressed adults and children
  • Adults and children with conditions that can compromise respiratory function, handling of respiratory secretions, or increase risk of aspiration
  • Residents of nursing homes and other chronic-care facilities.

At risk but cannot receive vaccine:

  • Infants younger than 6 months

  • Healthcare providers
  • Healthy household contacts (including children) and caregivers of:
    • Children birth-59 months of age, adults >50 years
    • Children and adults with medical conditions that put them at increased risk for severe complications from influenza

Emphasizing the Permissive Component of the Seasonal Recommendations

Vaccination is recommended for persons, including school-age children, who want to reduce the likelihood of becoming ill with influenza or transmitting influenza to othersshould they become infected.

why is it so important to vaccinate healthcare providers hcp
Why is it so Important to Vaccinate Healthcare Providers (HCP)?
  • HCP contact infected materials from patients
  • HCP have direct contact with HR patients every day
  • Transmission of disease seen in many different healthcare settings
  • HCP immunity is key to infection prevention and control programs
which hcp need vaccination
Which HCP Need Vaccination?
  • Includes physicians, nurses, nursing assistants, therapists, technicians, EMTs, dental, pharmacists, laboratory personnel, autopsy, students, trainees, contract staff, persons potentially exposed to infectious agents that can be transmitted to and from HCP.
  • Settings include hospitals, nursing homes, skilled nursing facilities, physicians’ offices, urgent care centers, outpatient clinics, home healthcare, and emergency medical services

...unvaccinated healthcare workers can be the index case for influenza in a facility, potentially posing a threat to high-risk patients and other workers.

May 2004,32(3)

why don t healthcare providers get vaccinated
Why Don’t Healthcare Providers get Vaccinated?

There are many reason, including:

  • Insufficient time, inconvenient
  • Belief that vaccine doesn’t work
  • Belief that you can get the flu from the flu vaccine
  • Concerns about adverse events
  • Perception of low risk of influenza disease
  • Misperceptions about risk of transmission to high risk patients
  • Avoidance of all medications
  • Fear of needles
strategies for improving hcp vaccination rates
Strategies for Improving HCP Vaccination Rates
  • Education and campaigns
  • Improved access to vaccine
  • Vaccination clinics
    • Mobile carts
    • Access during all work shifts
  • Institutional role models
  • Measurement and feedback
practice based influenza vaccination
Practice Based Influenza Vaccination
  • Standing Orders: Make the process as easy as possible, let the front office initiate the question about status, and the vaccine can be delivered as soon as possible. This has great utility for all vaccines and avoids missed opportunities.
  • Educate Staff: They must believe in the utility of vaccination even if just from a financial viability standpoint.
practice based influenza vaccination1
Practice Based Influenza Vaccination
  • Utilize influenza immunization as a Preventive visit. Payers often compensate for preventive health visits and thus an E & M code can be attached with proper documentation.
  • Update other Vaccines at the same time, Meningococcal vaccine, Tdap, Pneumovax, Zoster etc. can all be given concomitantly

Practice Based Influenza Vaccination
  • Other preventive screening can be addressed at the same time, i.e. cancer screening, colon breast, cervical and prostate…
  • In general, influenza vaccine lasts through June 30. Vaccination anytime (from start of vaccination season through June 30) may provide at least some coverage

Practice Based Influenza Vaccination
  • Above all be sure that all staff have received vaccine, as they will be able to counter the many myths about ‘flu’
  • Be familiar with the very few real contraindications and use vaccine liberally during acute visits.
  • Virtually every patient can be linked to a target population (especially Household, close contacts)
the changing paradigm
The Changing Paradigm…
  • We must:
    • Push to better immunize direct contacts of the vulnerable
    • Support advances in vaccine production technology and expansion of current capacity
    • Adapt messages about the timing of vaccination to take vaccine production/distribution into account
      • For BOTH providers AND the public
      • Messages about timing of vaccination must take supply and distribution into account as well as disease epidemiology
        • Begin vaccinating as soon as doses become available
        • October distribution is variable—so providers planning clinics and persons seeking vaccination must take this into account
        • Vaccination activities must continue throughout all of November and then cross Thanksgiving into December and beyond
    • Broaden the vaccination season [again!]
it is medically relevant to immunize throughout the entire season

at all times we should
At All Times, We Should…
  • Work to immunize until vaccine runs out
    • In accordance with ACIP recommendations
    • Move toward universal influenza recommendation
    • HCW Immunization must be improved
      • Not only patient safety issue but also role modeling
    • Improve communications to providers and public on the complexities of influenza vaccine production and if supply issues arise
