Support for references in typeFilters when using $export

[Patrick Palacin]

Hi guys,

as stated here the $export endpoint on Patient is not yet implemented:

https://smilecdr.com/docs/bulk/fhir_bulk_export.html

Nevertheless, we want to offer our doctors/evaluators to export records of a single patient with a given set of related resources. I tried to implement it via the system-level $export endpoint, but using references with the typeFilters doesnt seem to work:

curl --location --request POST 'http://localhost:8080/fhir/$export' \

--header 'Content-Type: application/json' \

--header 'Prefer: respond-async' \

--header 'Authorization: JWT XXXX' \

--data-raw '{

"resourceType": "Parameters",

"parameter": [

{

"name": "_type",

"valueString": "Patient,Observation,MedicationUsage,DiagnosticReport"

},

{

"name": "_outputFormat",

"valueString": "application/fhir+ndjson"

},

{

"name": "_typeFilter",

"valueString": "Patient?_id=517f2f9a-885a-11ea-9e44-327dcc10d7f6"

},

{

"name": "_typeFilter",

"valueString": "Observation?subject=Patient/517f2f9a-885a-11ea-9e44-327dcc10d7f6"

},

{

"name": "_typeFilter",

"valueString": "MedicationUsage?subject=Patient/517f2f9a-885a-11ea-9e44-327dcc10d7f6"

},

{

"name": "_typeFilter",

"valueString": "DiagnosticReport?subject=Patient/517f2f9a-885a-11ea-9e44-327dcc10d7f6"

}

]

}'

Unfortunately the created files contain all Observation, MedicationUsage and DiagnosticReports, not only limited to the ones for the Patient I requested.

Does anybody run into the same problem or has an idea how to solve it?

I am glad sharing our solution as soon as I found one.

Best

Patrick
