#FHIR

I'm using this service to create a FHIR facade. 
I want to return OperationOutcome to the calling application when I detect an error. 
My code at present is :

set quickStreamOut=##class(HS.SDA3.QuickStream).%New()

set operationOutcome = ##class(HS.FHIR.DTL.vR4.Model.Resource.OperationOutcome).%New()

s issue = ##class(HS.FHIR.DTL.vR4.Model.Element.OperationOutcome.issue).%New()

s issue.severity = "error"

s issue.code = "exception"

s issue.details = ##class(HS.FHIR.DTL.vR4.Model.Datatype.CodeableConcept).%New()

try {

s issue.details.text = exception.

I thought I knew how to return a Response from a Business Process back to the Source Config Name, but I guess not. 

I am working on a Proof of Concept, that the Request Message Class would determine a "Route" within a Business Process to make a FHIR call (search, read) to our External FHIR repository, and return back the HS.FHIR.DTL.vR4.Model.Resource.xxxxxxx as a Response to the Source Config Name.

I have the FHIR part working, however now that I have the data in the form of HS.FHIR.DTL.vR4.Model.Resource.

Hi,
I need to create a bundle of synthetic data in order to populate FHIR servers (not mine).

Can I use a predefined ids, or is it possible the one of the servers will not allow using my IDs and replace them with it's automatic numbering?

Currently in the health connect code, we are using Epic FHIR API Patient.Create, code return 200 or 201 status values, we process the message based on this return values.

Now I need to use Epic FHIR Patient.$match API, need to check FHIR Error code 4101 for this API. I looked for FHIR statndard return code, but this this seems not standard code, please advice how can I check 4101 value?

Needs some help with FHIR return code 200 or 201 when processing HL7 messages in HealthConnect.

Issue:

1. If FHIR code is 200 or 201, HealthConnect keep processing HL7 messages

2. If FHIR code is NOT 200 or 201, HealthConnect keep suspend the HL7 messages in the messages queue, then keep processing NEXT subsequent HL7 messages in the TEXT file if the FHIR code is 200 or 201

3. I am also using following "Reply Code Actions" in Operation settings (:?R=S,:?E=S,:~=S,:?A=C,:*=S,:I?=W,:T?=C)

Please advice if I have a "if condition check" for FHIR codes 200 or 201, what "Reply Code Actions" I should use?

I have been struggling sometime with trying to take a FHIR Bundle Response, extract the "entry.resourceType", extract the MRN and Name from the Patient FHIR Response...

Going through learning.intersystems.com, it suggested that I try using fhirPathAPI to parse and search my response for certain values, however I am not sure my syntax is correct. Using the AI code, it suggested to set my tree = "Bundle.entry.resource.resourceType"

ClassMethod Transform(source As HS.FHIRServer.Interop.Response, target As osuwmc.Epic.FHIR.DataStructures.

I was wondering if anyone had a way to automate creating the Query String for a FHIR Request?

Using HS.FHIRServer.Interop.Request in my development I have to specify the following...

I was wondering.... if my source had variable number of fields if there was a way to automate the build for the QueryString when doing a Patient Search?

I am trying to replicate a way to use FHIR as a way to query the EMR instead of using a MS SQL Stored Procedure that is populated via HL7 ADT to query.

I'm new to HealthShare. I've installed a demo using the HS.Util.Installer helper, now I'm playing with its FHIR Gateway (which is the HSFHIR namespace). When I try to create a new resource of type Patient using HTTP POST, HealthShare responses with

{
  "resourceType": "OperationOutcome",
  "issue": [
    {
      "severity": "error",
      "code": "not-supported",
      "diagnostics": "<HSFHIRErr>InteractionNotSupported",
      "details": {
        "text": "Interaction 'create' is not supported for resource type 'Patient'.

I built a BP, that every time that a message is received from a BS, it executes 

 set isAuth=##class(%SYS.OAuth2.AccessToken).IsAuthorized("EpicFHIRPOC",,,.accessToken,.idtoken,.responseProperties,.error)
 if 'isAuth {
        set tSC=##class(%SYS.OAuth2.Authorization).GetAccessTokenClient("EpicFHIRPOC", "*",, .error)        
         set isAuth=##class(%SYS.OAuth2.AccessToken).IsAuthorized("EpicFHIRPOC",,,.accessToken,.idtoken,.responseProperties,.error)
    }

To save time, I was thinking of just creating a BS that goes out and gets the Authorization Token every hour.

As I am iterating through the FHIR JSON Response from a Patient Search, I am running into an issue where the extracted values are not being popualted into the Response object that I have created. If I do a $$$LOGINFO on them they will show up in the Object log, however if I try the following for example I get an error.

set target.MRN = identifier.value

Here is my Ens.DataTransform

Class osuwmc.Epic.FHIR.DTL.

I am trying to centralize our FHIR queries into a single BP object that would send the FHIR query to the EMR, interpret the response into a %Persistent structure that could be sent back to the requestor. In theory it seemed like it would work but I am running into an issue..

"Warning on Message body 5@osuwmc.Epic.FHIR.DataStructures.PatientSearch.Record'

Hi, 
Our production FHIR server is populated by several processes from several sources, 
some of those sources send test data or wrong data (by mistake or as part of an integration test), 
the data is consumed by our BI every 15 minutes.
when I mark a resource as test (using meta security) BI knows to update it on their system.
everything is fine up to here (except that there is test data in Prod)
my problem is that if someone send the same patient again it will recreate the patient without the security tag.
any thoughts?
 

Hi,

Does IRIS have any support for paginating FHIR searches other than the standard next/prev links as defined in the FHIR spec?  For instance, some servers support an _offset or _skip parameter to allow for jumping to specific pages in a result set.  

Hi,

I'm using the iris for health community edition and I cannot seem to get the FHIR server configuration UI to show up.  I was able to create a FHIR server programaticlly but none of the user interface features that the installation guide talks about are available.  Once I was created the server I was able to see a Bulk FHIR Coordinator in the management portal, ut that's it.  Are the UI features not available in the community edition or do they need to be enabled somehow? 

This is the guide that I am using   https://docs.intersystems.com/irisforhealth20251/csp/docbook/DocBook.UI.Page.cls?

I have a quite complex FHIR Implementation Guide (IG) which is based on several other FHIR IGs. It's likely the versions of IGs conflict with each other.
From what I understand, I would need to load in all the other FHIR IG's first? 
I don't actually need FHIR profiles to be in our FHIR Repository - I'm just after terminology and the examples for our test system.
Is it possible to load a FHIR IG just as data? (I think I mean here, ignore the FHIR profiles and dependencies between them)

Hi,

  We have some concerns on how to implement FHIR, do we do facade?, how do we get resources?, what is a resource?, is a resource "Patient" or an instance of a patient?, How can we have a FHIR repository AND send the patient details to healthshare MPI?

  Has anyone correctly created a FHIR server that has custom methods?, handles "normal" methods and forwards onto Healthshare MPI , processing the response and creates a accurate FHIR response back to the calling system.

Hi Everyone,
Please suggest/share best practices and sample questions that would help me to secure InterSystems HL7 specialist Certification.

Dear InterSystems-Maintainer Team,

I am currently conducting a comparative evaluation of FHIR clients as part of my
bachelor thesis in health informatics. One of my evaluation criteria is the response
time to support inquiries.

Therefore, I would like to kindly ask the following question as part of my analysis:
How can I read and write custom FHIR extensions using your client library?

If available, could you point me to any documentation or examples?

Many thanks for your time and support!

Kind regards,
Rüya Gökoglu

I am making a FHIR request against Epic, in when I get the Response back using "fromDao" I am extracting the stream into HS.FHIRModel.R4.Patient. However, the patient's name comes back as name within a list that references HS.FHIRModel.R4.SeqOfHumanName.

• How do I extract the name from HS.FHIRModel.R4.SeqOfHumanName?
• Do I have to then do another "fromDao" to pull the list into string format?
• How do I navigate around the lists that are in a FHIRModel response, to extract the string values?

So I have been working in Healthcare Interops for about a month now and in IRIS. I am looking to implement SMART on FHIR and I am currently working to make an endpoint that works as the discovery endpoint. It is a custom dispatch class and unauthenticated is selected for access. I am trying to make a simple get request from Postman to test that the proper JSON is sent, but I receive a 403 Forbidden error. It is reaching IRIS it seems so I know its not a reverse proxy error. Here is an example of my custom Dispatch Class.

I am receiving a FHIR response bundle back with a resource of patient. Using fromDao, I attempted to take the stream and put it into FHIRModel.R4.Patient but it is not mapping correctly. When I attempt to take FHIRModel.R4.Patient and write it out using toString(), all I am seeing is the resource

{"resourceType":"Patient"}

so the response is not mapping correctly to FHIRModel.R4.Patient. How have others handled this? Do I need to translate it to an SDA since it does fit the model format?

I have created a new docker stack with webgateway and IRIS for Health 2025.1. I have mapped the posts of wegateway like this:

• 8743:443
• 8780:80

I can access IRIS portal through 8743 without problems.

I also have created a FHIR repository, and I'm able to access it through 8743 port.

I have a web application, in another server with another domain, that connects to this FHIR repository. I have configured in FHIR endpoint the allowed origin to the domain of this application.

Hello Developers,

I have MacBook Pro M3 and I'm new to the IRIS for Health setup / installation with all pre-requisite / requirements so someone could please help me with detailed instructions on how to setup IRIS for Health (HL7 & FHIR) from scratch along with SQL Server? I have Windows 11 installed in parallel desktop if that's required and complete installation / setup is not possible on MacBook.

Thank you in advance.

Hi guys,

I am looking for a way to search for FHIR Encounter resources from an InterSystems FHIR server where there period.start is before or after a certain time. I can´t get my head around which would be a correct way to do this since docs and FHIR spec is not clear to me which fields can be used for searching with wich prefixes.

In my local InterSystems FHIR server I have a set of Encounter ressources, each set with a period.start and (possibly) a period.end. I´d like to retrieve all Encounters with a start date time prior to a given datetime. I did a little testing with URL parameters.

I'm experimenting with FHIR bulk data load using NDJSONs, so far the import is running smoothly, but when I'm trying to perform a request of kind /Patient or /Procedure I'm getting back the following error:

{
    "resourceType": "OperationOutcome",
    "issue": [
        {
            "severity": "error",
            "code": "too-costly",
            "diagnostics": "<HSFHIRErr>SearchTooCostly",
            "details": {
                "text": "Search selects more than maximum allowed number of results (1000).

Hello,

I'm trying to POST a Location resource to a FHIR Server, but I get this error:
{
    "errors": [
        {
            "code": 5002,
            "domain": "%ObjectErrors",
            "error": "ERRORE #5002: Errore di Cach�: <PROTECT>zNewInteractionsInstance+1^HS.FHIRServer.Storage.Json.InteractionsStrategy.1",
            "id": "ObjectScriptError",
            "params": [
                "<PROTECT>zNewInteractionsInstance+1^HS.FHIRServer.Storage.Json.InteractionsStrategy.1"
            ]
        }
    ],
    "summary": "ERRORE #5002: Errore di Cach�: <PROTECT>zNewInteractionsInstance+1^HS.

I'm working on FHIR project and using this code to convert an incoming request to FHIR 

Method OnRequest(request As HS.FHIRServer.Interop.Request, Output response As HS.FHIRServer.Interop.Response) As %Status

{

    #dim tSC As %Status = $$$OK

    Try {

        // Process incoming request

        set stream = ##class(HS.SDA3.QuickStream).%OpenId(request.QuickStreamId)

        set bundle = ##class(HS.FHIR.DTL.vR4.Model.Resource.Bundle).

I have a scenario where I send a GET request to a broker and receive a FHIR response. When I attempted to use the built-in InterSystems functions to convert this FHIR response into SDA, the transformation failed—likely because it is not a standard FHIR request.

How should I handle this situation? Is there a recommended approach to processing FHIR responses in this context?

Additionally, if I manage to convert the FHIR response into a request format, I noticed that the broker sends a Task resource.
