## Immunization Registry Sentinel Sites 

- 2nd Quarter 2005 Data

## 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**

## 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**

## 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**

## Criteria for Site Selection

**Capacity-building Sites**
**Population of ****>****10,000 children****<6 years of age**
**≥****75% vaccine data submitted and processed within 30 days of vaccine administration**
**>95% private and public provider participation**
**>95% child participation for children ****<6 years of age**
**Population-based registry**

## Criteria for Site Selection

**Implementation Sites**
**≥****200,000 children ≤18 years of age with at least 50,000 children ****<6 years of age**
**≥****75% vaccine data submitted and processed within 30 days of vaccine administration**
**>95% private and public provider participation**
**>95% child participation for children ****<6 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 <6 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 > 30 days. Restrict the search to children aged <6 years who have been vaccinated within the past three months (February 16, 2005 - May 15, 2005) ]**

## Timeliness of Registry Data

**Notes:**
The sentinel sites are also evaluated on the timeliness of their data. All sites should aim to have all vaccination data in the study area captured in the registry within 30 days of vaccine administration.

The sites were asked,”For the children in your sentinel group who are <6 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 > 30 days. Restrict the search to children aged <6 years who have been vaccinated within the past three months (February 16, 2005 - May 15, 2005).”

Sites provided data quality plans on how they will use NIP funds to meet or maintain this standard. 

## 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.**
