Topic: Address: no fixed address

Brett Esler (Apr 18 2017 at 04:13):

Would there be any good advice on how to represents 'no fixed address' using Address datatype? Would like to make a positive assertion that a persion has no fixed address

Grahame Grieve (Apr 18 2017 at 05:16):

typically, NFPOA in the first line of the address

Alexander Henket (Apr 18 2017 at 05:23):

I do not know what NFPOA means, but I'd expect that systems here would populate a phys and/or postal address and may or may not mark that temp. Explicitly asserting "no fixed address" is something I think we do not do.

Grahame Grieve (Apr 18 2017 at 09:35):

NFPOA = No Fixed Place of Abode. I think about 1% of the patients I dealt with had this status

Brett Esler (Apr 18 2017 at 22:08):

thanks was looking for a more assertive way of doing this - this is very common is some nursing and outreach programs (e.g. homeless persons program). Am thinking of some kind of flag or coding extension on Address to indicate this.

Sarah Gaunt (Oct 31 2019 at 21:08):

@Brett Esler did you ever add a flag or extension for this - looking to do the same thing would like to re-use if possible...

Hi @Sarah Gaunt this is our STU3 profile in AU Base - will also appear in R4 version soon http://build.fhir.org/ig/hl7au/au-fhir-base-stu3/StructureDefinition-au-address.html - includes a no fixed address flag (extension); we decided to constrain text content and force address to be physical when set; we still allow suburb, state, country and postalcode etc to allow for things like no fixed address - west melbourne

Thanks @Brett Esler

We are facing the same issue. What was the rational to use a boolean extension over nullFlavor extension? In my mind the latter may provide better granularity.

Richard Townley-O'Neill (Dec 20 2019 at 06:06):

No fixed address is different to any of the null flavours relevant to address: no information, not known, not asked, not applicable, etc. are all in meaning different.
