4.11 QUERIES FOR IMMUNIZATION RECORDS (QRF SEGMENTS)

The VXQ, VXX, and VXR messages defined below incorporate the QRF segment defined at 2.10.5. QRF-5-other query subject filter is a locally defined filter for use between two systems which mutually agree on a definition. For transferring vaccination administration data, QRF-5 should be structured as shown in Figure 4-20 to transmit up to ten separate search "keys". These search keys are only used to identify one patient’s immunization record. The message provides for a wide variety of "identifying" keys including mother’s and/or father’s name and other identifiers; in some cases such information will be needed to identify a specific patient in the immunization database.

The format of each of the possible "search keys" is given below, and listed in a more structured form in Figure 4-20. These keys are transmitted as strings separated by repeat delimiters. The position of the components within QRF-5-other QRY subject filter is significant. The requester sends values for all the components that are known.

Components: <patient social security number>~<patient birth date>~<patient birth state>~<patient birth registration number>~<patient medicaid number>~<mother's name last^first^middle>~<mother's maiden name>~<mother's Social Security number>~father's name last^first^middle>~<father's Social Security number>.
