#FHIR

I am still trying to understand and come up with a use case to use FHIR as an enhancement to our existing HL7 messages. Does anyone have an example of taking a FHIR response and transforming it into a SDA?

How does the workflow go? Does it go through 1 BP?

Thanks

Hi colleages!

This is very easy to setup a FHIR server in InterSystems IRIS for Health.

It could be even one IPM command with this package:

USER>zpm "install fhir-server"

But which FHIR portal could you recommend to use?

I used to work with this one, which is very easy to install too:

USER>zpm "install fhir-portal"

but it doesn't work at the moment and I'm not sure if its main contributors @José Pereira and @Henrique Dias plan to support it.

What do you use? What do you recommend? Ideally installable with IPM package manager. Thanks!

I finally figured out how to get JWT token using set x = ##class(%SYS.OAuth2.Authorization).GetAccessTokenClient("medbank","openid fhirUser",.prop,.err).

I also found iris-fhir-client app on Open Exchange. I registered Epic sandbox server, but I cannot list resources. I suspect I need to integrate authorization / authentication. How do I do this with irisfhirclient py?

Hello All,

Having a recent project to create a FHIR repository, I want to know (as looking at the code) if HealthShare FHIR implementaton supports subscriptions?. I know it records the subscriptions ok, BUT does it handle sending the subscription out (based on the tags) to an endpoint (i.e. when a new FHIR request commits data that would trigger the subscription) ?, I'm 50% it doesn't, but would rather find out for sure before shoe horning something in.

Regards

Hello everyone,

I am working with InterSystems IRIS and seeking guidance on how to perform specific tasks related to the FHIR SQL Builder using commands or code, rather than the graphical user interface (GUI). The specific tasks I am trying to accomplish are:

Hello,

We are preparing for the MIT hackathon and noticed that when using the cloud services for FHIR, there isn't enough or any Patient data to test the FHIR APIs. Which sample patients can we use?

Hello Greetings-

I am exploring on converting HL7 to FHIR.

1. I saw there are built in DTLs “FHIR.FromSDA” and “FHIR.ToSDA” to convert SDA -> FHIR and FHIR -> SDA. Similarly Do Intersystems have DTLs for HL7 -> FHIR and FHIR -> HL7?

2. The reason why I am asking is, I see in HSLIB namespace HS->GateWay->HL7->HL7toSDA3 and HS->GateWay->SDA3->SDA3toHL7 DTLs. Like-wise I am trying to locate HL7 -> FHIR and FHIR -> HL7. Please help me to locate them

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).FromJSON(stream,"vR4")

Working on a project where I'm needing to make FHIR calls from my HealthConnect Interop production to Epic.

My issue is I'm not able to construct a valid JWT for the OAuth token retrieval that Epic will accept. I have the below code where I'm able to create a valid header and payload that I'm base64URL encoding and then trying to sign with my .pem private key file. However, Epic is not liking the signature portion of my JWT.

Im playing whack a mole importing an IG (which is a fairly typical exercise with fhir packages) through FHIR packages, and getting at some parts I cant seem to work around with some store errors...

Im getting MAXSTRING on `hl7.terminology.r4`:

Cures Act USCDI/ C-CDAv21 certification. I am looking for SDA3 examples for Newman-Bates-Kid/registry settings/advices on how to learn / whatever is helpful. InterSystems xsl files are clean but I am not working very often with xsl. I am mainly looking at Provenance and Clinical Notes, the 2 last errors we have. InterSystems documentation, so far I know, is very poor: only classes and some pages. Support has a small knowledge about SDA3 -> C-CDAv21 even if they try very hard to help.

I have an interoperability production that functions as a FHIR proxy. I have a need to add an HTTP Header value to the outbound request. I've subclassed HS.FHIRServer.Interop.HTTPOperation, but I cannot find a way to add an HTTP Header to the request. The HTTP class used in HS.FHIRServer.Interop.HTTPOperation is HS.FHIRServer.RestClient.HTTP. That RestClient class does not seem to expose or allow modification of the actual HttpRequest.

Hi

While configuring FHIR Server I could not find "Health > FHIR Configuration > Server Configuration" option. I am using InterSystems IRIS community edition on my local PC.

Thanks

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?
