Hello.

I have a channel in Mirth Connect that receives V2 ADT, transforms into FHIR JSON and persists in HAPI FHIR.

The transformed resource is this:

{

"resourceType": "MessageHeader",

"source": {

"name": "NES"

},

"destination": [

{

"name": "openEMR"

}

],

"date": [

{

"resourceType": "Patient",

"gender": "M",

"birthDate": "1985-01-01",

"identifier": [

{

"use": "usual",

"type": {

"coding": [

{

"system": "http://hl7.org/fhir/v2/0203",

"code": "MR"

}

]

},

"value": "123456789"

}

],

"name": [

{

"family": [

"HOUSE"

],

"given": [

"GREGORY"

],

"text": "GREGORY HOUSE"

}

]

}

]

}

When I receive the message through Mirth, the error occurs:

ER7Serializer error

ERROR MESSAGE: Error converting XML to ER7

But when I use the POST through postman the resource is created: 201 (with some errors because the resource is not complete, it is a test at the moment)

{

"resourceType": "OperationOutcome",

"text": {

"status": "generated",

"div": "<div xmlns = \" http: //www.w3.org/1999/xhtml \ "> <h1> Operation Outcome <table border = \" 0 \ "> <tr> </ Successfully created resource & quot; MessageHeader / 420097 / _history / 1 & quot; in 1ms <td style = \ "font-weight: bold; \"> INFORMATION </ td> \ n \ t \ t \ t \ t \ t \ t \ t \ t \ \ n \ t \ t \ t \ t <td style = \ "font-weight: bold; \"> ERROR </ td> \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ <td> </ td> <td> <td> <td> <td> <td> t </ t> \ n \ t \ t \ t <tt> t <td style = \ "font-weight: bold; \"> ERROR </ td> \ n \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ n \ t \ t \ t \ t \ t \ t <td> <pre> Profile http://hl7.org/fhir/StructureDefinition/MessageHeader, Element 'MessageHeader.event': minimum required = 1, but only found </ Td> </ td> </ td> </ td> </ td> <td> <td> </ td> </ td> <td> <td class = \ "font-weight: </ td> \ n \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t <td> <pre> Profile http://hl7.org/fhir/StructureDefinition/MessageHeader, Element 'MessageHeader.timestamp': minimum required = 1, but only found 0 </ pre \ n \ t \ t \ t \ t \ t \ t \ t \ t \ t \ \ n \ t \ t \ t \ t <td style = \ "font-weight: bold; \"> ERROR </ td> \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ <td> <pre> Profile http://hl7.org/fhir/StructureDefinition/MessageHeader, Element 'MessageHeader.destination.endpoint': minimum required = 1, but only found 0 </ pre> </ td> \ n \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ n <td style = \ "font-weight: bold; \"> ERROR \ n \ t \ t \ t \ t \ t <td> [MessageHeader.source] </ td> \ n \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ t \ : //hl7.org/fhir/StructureDefinition/MessageHeader, Element 'MessageHeader.source.endpoint': minimum required = 1, but only found 0 </ pre> </ td> \ n \ t \ t \ t \ t \ \ n \ t \ t \ t \ t \ t \ t \ t \

"issue": [

{

"severity": "information"

"code": "informational",

"diagnostics": "Successfully created resource \"MessageHeader/420097/_history/1\" in 1ms"

What I need is to persist the patient on the FHIR server ....

If a FHIR server does not support the MessageHeader feature, can I insert only the patient?

Tks,

Paulo

Your resource looks invalid. Patient looks as though it’s in the date part of message header.

I would have expected to see both resources within a bundle resource

Hi Kevin. Thanks for the feedback.

I generated the Patient resource in conformance to spec and everything worked fine.

Cheers
