BACKGROUND:
In CY2001, 12 state/district registries used their data to assess school vaccination coverage. Immunization registries may be a useful tool to estimate school vaccination coverage levels if the school districts and registries contain complete records and exchange data.
OBJECTIVE:
Compare the vaccination histories housed in school records with data in immunization registries in school districts for data accuracy and completeness.
METHOD:
Schools were selected randomly from a defined metropolitan area in Phoenix, AZ and San Antonio, TX. Staff from health departments pulled the school records for each kindergartener in the 2002-2003 class and recorded demographic and immunization information. 599 records from AZ and 851 records from TX were analyzed. School record data were matched with data in immunization information systems. Data were analyzed using SAS version 8.2.
RESULT:
Preliminary analyses indicate that 85.8% of the children in the AZ school records were matched to the registry compared to 76.2% in San Antonio. For children who were located in both school and registry data, 95.1% in AZ and 85.6% in TX were up-to-date on immunizations required for school entry using solely school data. When only registry data was used, 31.9% in AZ and 74.8% in TX were up-to-date. Only 1.0% in AZ and 2.5% in TX were up-to-date in the registry data, but not school data.
CONCLUSION:
Registries were more likely to have missing vaccinations and doses than the school record. Examination of specific vaccines may identify some potential areas to improve data quality.
LEARNING OBJECTIVES:
Compare the data quality of school record and immunization registry vaccination histories
