Arizona Takes Lead in Developing Capacity for Immunization Information Exchange

Arizona has one of the country's highest managed care penetration rates and a relatively consolidated managed care market. To capitalize on this environment, ASIIS decided to develop the capacity and technical assistance for MCOs to connect to the ASIIS Authorization Gateway and use Health Level Seven (HL7), a coding standard approved by the American National Standards Institute, for exchanging immunization information.

To achieve the vision of a nationwide system of immunization registries, all immunization registries ultimately must be able to exchange information with one another. HL7 standards enable that exchange.

The Center for Disease Control and Prevention's National Immunization Program has included the ability to exchange information using HL7 among the 13 functional requirements of a fully operational registry.

ASIIS was one of two All Kids Count projects that were able to communicate immunization information using the HL7 standard by June 2000.
