[DUPLICATE] Progress in immunization information systems --- United States- 2009.

An

immunization information system (IIS) is a confidential-

computerized- population-based system that collects and

consolidates vaccination data from vaccine providers and provides

tools for designing and sustaining effective immunization

strategies at the provider and program levels. Among the

capabilities of an IIS are the capacity to inform vaccine providers

of upcoming patient vaccination needs/ generate vaccination

coverage reports- patient reminders- or recalls for past due

vaccinations/ and interoperate with electronic health record (EHR)

systems. In 2010- the Task Force on Community Preventive Services

recommended that immunization information systems be used to

increase vaccination coverage after showing strong evidence of

their effectiveness. A Healthy People 2020 objective is to increase

to 95% the percentage of children aged <6 years whose

immunization records are housed in a fully operational IIS. To

assess IIS progress toward meeting the Healthy People objective-

CDC analyzed data from the 2009 Immunization Information Systems

Annual Report (IISAR) survey (completed by 53 of 56 federal

grantees with IIS sites)- which indicated that 77% of all U.S.

children aged <6 years participated in an IIS- an increase from

75% in 2008. In addition- 59% of grantees reported being able to

send and receive vaccination data using Health Level Seven (HL7)

messaging standards- and 73% reported that some vaccine providers

with EHR systems in their geographic area were providing

vaccination data directly to an IIS from EHRs. Enhancing IIS and

EHR with standards such as HL7 will provide greater consistency in

data exchange and likely help to improve the quality and timeliness

of IIS data.
