First, data from the 2003 IRAR
are self-reported and might result in reporting bias.
receive and process vaccination data within 30 days of vaccination, access information from the registry at the time of patient encounter, and produce reminder and recall notifications) reflected no increase in implementation at the state level, compared with six standards from the 2001 IRAR (5).
Data from the 2002 IRAR are self-reported and might result in reporting bias, although site visits to certain immunization registries have shown high concordance with IRAR data (5).
Because 2002 IRAR data are self-reported by immunization program managers, efforts are under way to validate responses using data from the National Immunization Survey (NIS), a random-digit-dialed telephone survey of vaccine providers for children aged 19-35 months that estimates vaccination coverage for all 50 states and 28 urban areas (7,8).
Editorial Note: The findings in this report indicate the continuation of a trend identified previously in IRAR surveys (4,5).
Because CY 2001 IRAR data indicated that some encounter-based registries are approaching or have reached the 95% participation goal, participants from all 51 grantee registries, both population-based and encounter-based, were included in participation rate estimates.
The 32 grantees also reported that an average of 56% of public vaccination provider sites and 41% of private provider sites in their catchment areas participated in the registry during the 6 months preceding completion of the CY 2000 IRAR.
CY 2000 IRAR data indicate that certain grantees might have the capacity to use registry data to support these program attributes.
The 32 grantees also reported that an average of 74% of public vaccination provider sites and 44% of private provider sites participated in a population-based registry during the 6 months preceding completion of the 2000 IRAR.
First, because IRAR 2000 relied on self-reported information, some bias is expected.
Editorial Note: The 1999 IRAR represents the first attempt to quantify and evaluate state-based and community-based immunization registry development in the United States.
First, because the IRAR relies on self-reported data, some bias is expected.
