Stream: finnish PHR
Topic: Finnish, swedish and general/"unknown" id
Lauri Karppinen (Feb 21 2019 at 06:54):
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
Example of what I'm trying to figure out:
"identifier": [
{
"type": {
"coding": [
{
"system": "?",
"code": "?"
}
]
},
"system": "?",
"value": "111111-111C"
}
],

I got reply from Sweden on FHIR that ("system": "urn:oid:1.2.752.129.2.1.3.1") would be used for swedish id. So I need something similar for Finnish SSN.
Lauri Karppinen (Feb 21 2019 at 09:10):
Could this be one to be used for finnish id: urn:oid:1.2.246.21? This was found from: https://esuomi.fi/suomi-fi-services/suomi-fi-e-identification/14247-2/?lang=en . Actually I used this system already for my implementation, but now I'm trying to fix mistakes and bugs during my implementation.

If you're asking this in relation to Kanta PHR, we don't actually store Finnish social security numbers in the Patient resources, we use uuids/pseudonyms as the identifiers (that are mapped to SSN in the PHR platform during the authorization code flow). For the Kanta PHR Sandbox without authorization functionality, we have published these instructions for creating Patients in the Sandbox environment https://www.kanta.fi/documents/20143/91486/Creating+a+Patient+resource+at+the+sandbox+environment+without+an+authorization+functionality.pdf/de51b2c7-edee-febd-570d-2d3e24e776be (this can be found on this website https://www.kanta.fi/en/system-developers/sandbox-environments).

But @Lauri Karppinen I can confirm the oid urn:oid:1.2.246.21 is the right one to use for this purpose. At least very widely used in various implementations in Finland.
Mikael Rinnetmäki (Feb 26 2019 at 09:41):
Regarding properly identifying the patients in Kanta PHR, the discussion (https://chat.fhir.org/#narrow/stream/179222-finnish-PHR/topic/Identifying.20the.20Patient/near/154005154) is still going on...
Latest proposal is a mechanism for an app to verify whether a known pseudonym and a known SSN do in fact match.
Lauri Karppinen (Feb 26 2019 at 12:48):
Thanks for the answer! It seemed like the right code to use. I will need to figure some workaround while waiting...
