The National Immunization Survey (NIS)

• Already heard what the NIS now does
• Planned expansions
• Urban areas beyond the current 28
• Age ranges besides 19-35 months
• Special purpose sub-surveys

Urban Areas in the Current NIS
4
Urban Areas

• The NIS has, from 1994 2004, surveyed 50 states
  and 28 selected urban areas
• Areas selected based on conditions prevailing in
  1994
• Immunization coverage for urban areas not on this
  list can only be estimated as part of larger area

5
Urban Areas, continued

• Example
• Suppose we wanted coverage for Denver, CO in 2002
• Have 2002 coverage for CO
• Number of children in Denver in 2002 too small
  for reliable estimate
• Can only give coverage for Denver by combining
  multiple years of data (this must be done with
  caution)

6
Urban Areas, continued

• Would like to add new urban areas beyond existing
  28
• have no resources
• Starting in 2005, plan to monitor certain urban
  areas every other year
• Use freed-up resources to monitor new urban areas
  on off years

7
Urban Areas, continued

• Current plans
• Rotated in Denver, Las Vegas, St. Louis, San
  Bernadino, Oakland (2005, 2007, 2009)
• Rotated out Boston, Indianapolis, Miami, San
  Diego, San Jose (will return 2006, 2008, 2010)
• Other urban areas might be rotated in/out in
  other years
• Discussions with NACCHO on this matter are
  ongoing

8
Other Age Groups

• NIS core mission produce state, urban, and
  national estimates of coverage for 19-35 month
  old children
• NIS is moving toward producing national level
  estimates of coverage for other age ranges as
  well
• Estimates by state or large race/ethnicity groups
  is a goal

9
Other Age Groups, continued

• Additional age ranges
• Adults aged 65 years (2003, 2004)
• Adults aged 50-64 years (2004)
• Adolescents aged 13-15 years (2004)
• Hope to continue these surveys in future years

10
Special Purpose Supplements (Topical Modules)

• Subsamples of NIS survey can be asked
  special-purpose questions
• insurance status day care and breast feeding
  attitudes and beliefs (2001, 2002)
• vaccine safety vaccine shortage (2003)
• vaccine safety vaccine shortage and childhood
  influenza (2004)

11
Special Purpose Supplements, continued

• The 2004 NIS survey of adults aged 65 years
  includes questions to assess cancer screening
  (done in partnership with the National Cancer
  Institute).
• Although no plans exist, similar partnerings
  might occur in the future.

Conclusion

• Historically NIS provided immunization coverage
  for 19-35 month old children in a fixed group of
  geographic areas
• Vision for the future NIS provides immunization
  (and occasionally other public health) related
  data for many age ranges, for many geographic
  areas
