Immunization Registry Sentinel Sites

1
Immunization Registry Sentinel Sites

• 2nd Quarter 2005 Data

2
Definition of a Sentinel Site

• A population-based registry that contains a
  population of children in a geographic area with
  complete vaccination histories so that changes in
  coverage can be rapidly detected and monitored

3
Purpose of the Sentinel Sites

• Timely detection of changes in coverage
• Determine if news events affect coverage of
  specific vaccine
• Ensure data quality of registry data
• Evaluate vaccine supply issues
• Evaluate implementation of new ACIP and NVAC
  recommendations
• Demonstrate the Usefulness of Registries

4
Types of Sentinel Sites

• Capacity-building sites
• Evaluation sites primarily working to meet data
  quality Immunization Registry Certification
  Standards and provide support for routine
  analysis of immunization registry data
• Implementation sites
• Evaluation sites that accurately assess trends in
  vaccination coverage for all children in study
  population and provide data for public health
  decision making

5
Criteria for Site Selection

• Capacity-building Sites
• Population of gt10,000 childrenlt6 years of age
• 75 vaccine data submitted and processed within
  30 days of vaccine administration
• gt95 private and public provider participation
• gt95 child participation for children lt6 years of
  age
• Population-based registry

6
Criteria for Site Selection

• Implementation Sites
• 200,000 children 18 years of age with at least
  50,000 children lt6 years of age
• 75 vaccine data submitted and processed within
  30 days of vaccine administration
• gt95 private and public provider participation
• gt95 child participation for children lt6 years of
  age
• Population-based registry
• Registry database with 5 duplicate records and
  a robust de-duplication algorithm that adheres to
  a minimum of 90 sensitivity and 100 specificty
• Registry database contains all core NVAC data
  elements

Timeliness

• GOAL Have all data captured in registry within
  30 days of immunization
• Query For the children in your sentinel group
  who are lt6 years of age as of May 15, 2005 (born
  between May 16, 1999 - May 15, 2005), please
  report the number of vaccine doses that are
  reported to the registry within the time frame
  specified in the table. Please exclude shot
  history data shot history data would
  artificially inflate the number of records
  classified in the categories gt 30 days. Restrict
  the search to children aged lt6 years who have
  been vaccinated within the past three months
  (February 16, 2005 - May 15, 2005)

Vaccination Coverage

• Describe vaccination coverage by age group and
  antigen
• Compare vaccination series data with data from
  past quarters and the 2004 National Immunization
  Survey (NIS) point estimate
• NIS provides estimates of vaccination coverage
  among children ages 19-35 months
• NOTE NIS data are not directly comparable to
  2005 sentinel site quarterly reports because of
  differences in population and time frame.
