[1..1] [M] classCode (CS { CNE: RoleClass } )

[0..1] addr (AD)

Model Attribute Description

The HL7 attribute addr uses an address for the person who has a relationship with the patient.

The HL7 attribute addr allows structured and unstructured addresses to be carried. Only structured addresses are recommended to be used.

Implementation in XML Instance

There are a number of forms of structured address. The three shown here are the recommended formats for patient addresses, they are listed in no particular order.

The XML element addr is populated as follows:

When using the structured address in the style of PDS the XML element addr shall contain five XML elements streetAddressLine:

  • The first XML element streetAddressLine shall contain the premises name
  • The second XML element streetAddressLine shall contain the number and thoroughfare
  • The third XML element streetAddressLine shall contain the locality
  • The fourth XML element streetAddressLine shall contain the post town
  • The fifth XML element streetAddressLine shall contain the county

The first XML element streetAddressLine or the second XML element streetAddressLine and the fourth XML element streetAddressLine are mandatory to be populated.

  • The XML element postalCode can be used to carry a postcode
  • The XML element addressKey can be used to carry a PAF key

When using the fully structured address format then the XML element addr shall be populated as follows:

  • The XML element houseNumber shall contain the house/building number or name
  • The XML element streetName shall contain the street name
  • The XML element city shall contain the city name
  • The XML element county shall contain the county
  • The XML element country shall contain the country name
  • The XML element postalCode shall contain the postcode
  • The XML element addressKey shall contain the address key

Note that unpopulated XML elements should not be present.

Alternatively the structured address may contain just a series of XML elements streetAddressLine populated in the correct order to render as a postal address with as much information as available included.

  • The first XML element streetAddressLine shall contain the first address line
  • The second XML element streetAddressLine shall contain the second address line
  • The third XML element streetAddressLine shall contain the third address line
  • and so on ....

Note that unpopulated XML elements should not be present.
