Topic: not US SSN
Lauri Karppinen (Feb 21 2019 at 07:00):
Hi. What type.coding and/or system I would need to use to present Finnish/Swedish/"uknown" id in identifier of Patient resource? There are only US SSN and different state drivers licences in FHIR speck: https://www.hl7.org/fhir/identifier-registry.html
I already sended this question to #Sweden on FHIR and #finnish PHR . But I will post it here too because I'm thinking that someone must have done something like this outside of US? How it should be done?
Example of what I'm trying to figure out:
"identifier": [
{
"type": {
"coding": [
{
"system": "?",
"code": "?"
}
]
},
"system": "?",
"value": "111111-111C"
}
],

Could the identifier even be used like this?
"identifier": [
{
"type": {
"text": "Finnish ID"
},
"value": "19811218-9876"
}
],
Identifier is extensible: https://www.hl7.org/fhir/datatypes.html#Identifier
and in here ( https://www.hl7.org/fhir/terminologies.html#extensible) its' said that "If there is no applicable concept in value set (based on human review), an alternate concept (either system/code pair, or text) may be used instead." https://www.hl7.org/fhir/terminologies.html#extensible
So would this be valid FHIR way to present these social security numbers? Just changing the text to Finnish/Swedish/Uknown?

Each country will need to determine the 'system' values for all of their "common public identifiers" - i.e. identifiers that tend to be captured in multiple places as opposed to only being captured by the system that assigns them. This will include provider license numbers, citizen identifiers, insurance identifiers, etc. The NamingSystem resource can provide a way of sharing and looking up these systems once they have URLs assigned. (You can also register them with HL7 if you wish.)

Without that, you can certainly follow your last example, but that's not going to be terribly computable. You could easily get a match between a drivers license and a provider license, as an example.

Australian identifiers are used in profiles of HL7 AU. For example, see http://build.fhir.org/ig/hl7au/au-fhir-base/StructureDefinition-au-patient.html

Patient.identifier has been sliced to demonstrate how to represent various national identifiers.
