Progress in immunization information systems - United States- 2010.

Immunization information systems (IIS) are confidential-

computerized- population-based systems that collect and consolidate

vaccination data from vaccination providers and provide important

tools for designing and sustaining effective immunization

strategies at the provider and immunization program levels. These

tools include clinical decision support- vaccination coverage

reports- interoperability with electronic health record systems-

vaccine inventory management- and the ability to generate reminder

and recall messages. In 2010- based on strong evidence of

effectiveness- the Task Force on Community Preventive Services

recommended IIS use as a means of increasing vaccination rates. A

Healthy People 2020 target (IID-18) is to increase to 95% the

proportion of children aged <6 years whose immunization records

are in fully operational- population-based IIS. To monitor progress

toward program goals- CDC annually surveys 56 immunization program

grantees (50 states- five cities- and the District of Columbia)

using the IIS Annual Report (IISAR). Results from the 2010 IISAR

(completed by 54 grantees) indicate that 82% (18.8 million) of U.S.

children aged <6 years participated in IIS- as defined by having

at least two recorded vaccinations- an increase from 78% (18.0

million) in 2009. Among 52 grantees who responded to questions

about the Vaccine Tracking System (VTrckS)- CDC\'s new national

vaccine ordering and inventory management system for publicly

purchased vaccine- 38 (73%) indicated their intention to use the

IIS in their state or city to interface with VTrckS. Use of IIS to

interface with VTrckS might provide additional incentive for

vaccination providers to participate in IIS and enhance IIS utility

by supporting efficient and effective methods for providers to

order vaccine and track inventory and by promoting greater

accountability of publicly purchased vaccine.
