Definition:This standard is for the storage and exchange of immunization data to provide an organized and streamlined means of communicating between Federal partners by offering a real-time means of transferring information regarding immunization encounters, vaccine events, patient records and other immunization related information important to immunization registries. For immunization registry terminology, the CHI standard is the use of CVX (clinical vaccine formulation) and MVX (manufacturer) codes from Health Level Seven (HL7). Also, the CHI designated messaging standard for exchange of immunization data is HL7 2.3.1, and future versions, as defined by Centers for Disease Control and Prevention (CDC) in the Implementation Guide for Immunization Data Transactions using Version 2.3.1 of the Health Level Seven (HL7) Standard Protocol Implementation Guide Version 2.1 (September 2002) available at: http://www.cdc.gov/nip/registry. Usability gaps noted were: Currently, there are minimal gaps within the messaging standard. It matches current data needs with respect to immunization registries. Gaps related to terminology exist, as they do not harmonize with product information standards that are currently under development. Data needs will evolve potentially requiring more robust clinical content from a standard vocabulary. Additional research needs to be done to assess those future data needs, and whether the specific reference terminologies could address those issues.
