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
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:
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.
To achieve optimized AI performance, robust explainability, adaptability, and efficiency in healthcare solutions, InterSystems IRIS serves as the core foundation for a project within the x-rAI multi-agentic framework. This article provides an in-depth look at how InterSystems IRIS empowers the development of a real-time health data analytics platform, enabling advanced analytics and actionable insights. The solution leverages the strengths of InterSystems IRIS, including dynamic SQL, native vector search capabilities, distributed caching (ECP), and FHIR interoperability. This innovative approach directly aligns with the contest themes of "Using Dynamic SQL & Embedded SQL," "GenAI, Vector Search," and "FHIR, EHR," showcasing a practical application of InterSystems IRIS in a critical healthcare context.

When we create a FHIR repository in IRIS, we have an endpoint to access information, create new resources, etc. But there are some resources in FHIR that probably we wont have in our repository, for example, Binary resource (this resource returns a document, like PDF for example).
I have created an example that when a Binary resource is requested, FHIR endpoint returns a response, like it exists in the repository.

FHIR repositories, applications and servers typically serve clinical data in small quantities, whether to return data about a patient, their medications, vaccines, allergies, among other information. However, it is common for a large amount of data in FHIR/JSON format to be requested to be used to load into Data Lakes, identifying study cohorts, population health, or transferring data from one EHR to another. To meet these business scenarios that require large extractions and loads of data, it is recommended to use the FHIR Bulk Data Access feature provided by HL7 institution.
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?
My main goal of this article was to prove the use of InterSystems IRIS for Health for REST FHIR interoperability between multiple applications. In this use case, some initiating application makes a REST call to IRIS for Health (which is merely a passthrough for REST calls) to retrieve FHIR data from an Oracle Health R4 FHIR repository. Ideally, it simplifies the syntax for calling the Oracle Health APIs.
Easy to use HL7v2 to FHIR, CDA to FHIR, FHIR to HL7v2 as a Service.
The aim of this project is to provide an REST API that can convert easily various health formats.
Post the desire format in the REST body, get the answer in the new format.
Everytime I try to send a POST FHIR bundle I'm getting the following response: 404 Not Found. I'm not really sure why, although it works fine with a GET!
This is an example:
Response:
It might be something related to request path but not really sure.
While working with GET request I encountered this situation where FHIR Server return a responseStatusHTTP "HTTP/1.1 200 200" instead of "HTTP/1.1 200 OK" (as highlighted in the attached screenshot).
Although the response code seems valid, these bundles have a total value of 0.
Could anyone clarify what "200 200" signifies in this context? Is there an issue with my setup, or does this indicate a specific condition related to the empty bundle search?
You may have noticed that to configure a mirror for InterSystems IRIS for Health™ and HealthShare® Health Connect there is a special requirement. I wanted to go through it step by step in this article.
I'm attempting to build a fairly complicated object graph, with nested objects and collections, in order to create a FHIR bundle.
In its most basic form there is a <bundle></bundle> element that represents the root, and there can be a number of nested <entry></entry> child elements.
I'm trying to customize error handling in the overriden HS.FHIRServer.Storage.JsonAdvSQL.Interactions::Search method. It is clear how to add to the resultset a valid FHIR resource (pseudocode):
I am trying to work with Epic on FHIR. Epic's documentation stated, your application makes a HTTP POST request to the authorization server's OAuth 2.0 token endpoint to obtain access token.
Set tSC = ##class(%SYS.OAuth2.Authorization).GetAccessTokenClient(pClient,pScopes,.prop,.err) returns
ERROR #9761: No key in provided JWKS for alg ES512 and kid
I check this /csp/sys/oauth2/OAuth2.JWTServer.cls?client_name=medbank and I see this:
Over the past couple of months, I have been working on the SMART on FHIR EHR Launch to test the capabilities of IRIS for Health using two open-source apps from CSIRO: SMART-EHR-Launcher and SMART Forms App. This journey has been incredibly interesting, and I’m truly grateful for the opportunity to work on this task and explore more of IRIS for Health’s potential.
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.
An extension “extends” or enhances a FHIR resource or a data element in a custom way. The extension can be added to the root of a resource, such as “Patient.ethnicity” in US Core profile, and they can be added to individual elements such as HumanName, Address or Identifier.
Did you know that you can also add an extension to a primitive data type?
Primitives usually store a single item and are the most basic element in FHIR. For example: "Keren", false, 1234, 12/08/2024 etc.
For example, the patient resources might look like this:

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?
