Fast Healthcare Interoperability Resources (FHIR, pronounced "fire") is a draft standard describing data formats and elements (known as "resources") and an application programming interface (API) for exchanging electronic health records

Official site

My IRIS instance is connected to a Postgres database using SQL Gateway and linked tables.
One of these tables is projected to the Patient class. I want to select a record from this table by ID and convert it to a FHIR resource using the %ExistsId and %OpenId methods.
I noticed that if I call these two methods from the console, the record is always found.

Error importing XSD

I'm attempting to import all the FHIR XSD files provided by http://hl7.org/fhir but get the immediate and unhelpful error message:

I've tried different versions of EOLs to no avail. Any idea what this error could mean?

Here's the XSD I'm trying to import:

<?xml version="1.0" encoding="UTF-8"?>

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?

I need to create a JWT to connect to EPIC FHIRserver sandbox.

https://fhir.epic.com/Documentation?docId=oauth2&section=BackendOAuth2Guide

You will generate a one-time use JSON Web Token (JWT) to authenticate your app to the authorization server and obtain an access token that can be used to authenticate your app's web service calls. There are several libraries for creating JWTs. See jwt.io for some examples.

I'm playing with some anayltic queries against FHIR server tables. The HSFHIR_X0002_S_Patient.addressCity table contains a lot of cities which names contain german charachers such as ä, ö and ü.

The following query works fine:

select value from HSFHIR_X0002_S_Patient.addressCity

But this one converts city names to uppercase, and characters with umlauts are lost, so instead of "Köln" or "München" I see KOLN and MUNCHEN:

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.

I am trying to use IRIS for Health as a Facade for an external FHIR Server, where IRIS provides the proper authentication.
The client authenticates using a bearer token obtained from the IRIS OAuth2 server via a jwt client assertion.
The IRIS endpoint, however, returns a 401 as soon as I remove the Unauthenticated access

Is there w way to make this work through configuration?

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.

As I begin our adventure into using an External FHIR Repository, I wanted to see what opinions people have about a design Idea I was working on.

I want to create a way that my Team has the ability to send a Message Type, and the system knows from that Message Type which FHIR queries to execute and return the Response back to the user, sort of like a FHIR Query Hub. Does this sound reasonable?

Using the FHIR DEMO, I have pieced together how to make a FHIR Request using OAuth against an External FHIR Repository. When I execute the Patient search (HS.FHIRServer.Interop.Request), I get a HS.FHIRServer.Interop.Response that has a Quick Stream ID, which I then use to convert the Quick Stream to a JSON Dynamic Object. if I do a trace on the Raw JSON Object, I am able to pull out single elements, however I want to pull the raw JSON into a defined Class Structure.

I'm running into an intermittent issue with some of our Custom Operations/Processes as a result of some large FHIR R4 Binaries. Essentially we get a response from an AthenaHealth FHIR endpoint that appears to be too large to be processed using the IRIS Built In Functions for FHIR:

I've replicated it on the command line here using a file (binary.json) that has the response from the FHIR Endpoint. Not sharing full contents due to PHI concerns.

Hello Community,

I'm a beginner and currently working on a project to convert CCDA files to FHIR using InterSystems IRIS. I have developed a web form to upload CCDA files, and I'm attempting to convert the uploaded CCDA files to FHIR. However, I am encountering an issue where the conversion process results in an empty entry.
Here's the Output it displays on HTML page:

Up until recently, I have been toying around with REST/FHIR capabilities but only internally. Now I have a request to make REST API calls outside of our Network.

I am using an RSA 4096 key, because Microsoft Active Directory Services which generates the signed certificate could not handle the Elliptical Key (ECC) when I put the request in.

IRIS for UNIX (Red Hat Enterprise Linux 8 for x86-64) 2024.1 (Build 267_2U) Tue Apr 30 2024 16:06:39 EDT [HealthConnect:7.2.0-1.r1]

I have a use case where Epic is sending an A60 Allergy transaction is set at the Patient level, but we have a system called VIBE which needs the ADT at an Encounter level instead. Currently we store ADT information in a MS SQL database for years, and we are querying it to get the latest Account Number to insert into the ADT^A60 for VIBE.

Hello everyone,

Recently, I've been working on a Business Process that processes a large JSON FHIR message containing up to 50k requests in an array within the JSON.

Currently, the code imports the JSON as a dynamic object from the original message stream, obtains an iterator from it, and processes each request one at a time in a loop.

I'm trying to complete Inferno Service Base URL test for FHIR endpoint and I thought it wanted host.com/fhir/r4/.well-known/smart-configuration but I get header error below. Am I using the wrong Service Base URL List or am I missing something? I'm running 2021.2 HealthShare

ERROR <HSFHIRErr>InvalidAcceptSpec: No valid Accept data found (Accept header or _format parameter)

I am trying to work with the FHIR Object Model where I convert an incoming HL7v2 to SDA then FHIR. From here I would like to be able to process the FHIR Object by deserializing it to a Bundle object using the following code my problem is I keep on getting an error which is not explaining much about what is wrong with what I am doing any help will be appreciated thanks.

I am attempting to make a FHIR call against the Epic Repository through Intersystems. I have setup a Service client per Create FHIR REST Client | InterSystems Developer Community | Business

but I have set it up using OAuth and HTTPS.

I have verified that the OAuth works by executing it manually via a Terminal to verify I get a response. Of course, when I do it is writing to the ISCLOG
