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
Hi Developers,
We are happy to announce the new InterSystems online programming contest:
🏆 InterSystems Programming Contest: AI Agents for FHIR🏆
Duration: May 25 - June 14, 2026
Prize pool: $12,000
Healthcare billing isn’t a pipeline. It’s a conversation about trust.
Every day, millions of clinical transactions flow from doctors’ keyboards to insurance ledgers. Standard health IT systems are built to count these transactions. They store them. They organize them.
They route them. But standard systems don't notice them.
We’ve built faster and faster databases to process claims, but we forgot to ask: Does this claim make sense?
Because we don’t ask in real-time, we’ve accepted a compromise. We pay first, wait six months, and then hire forensic auditors to find the mistakes.
Hi all,
It's me again 😁. In the pervious article Writing a REST api service for exporting the generated FHIR bundle in JSON, we actually generated a resource DocumentReference, with the content data encoded in Base64

Question!! Is it possible to write a REST service for decoding it? Because I am very curious what is the message data talking about🤔🤔🤔
OK, Let's start!
1. Create a new utility class datagen.utli.decodefhirjson.cls for decoding the data inside the DocumentReference
ClassExtends%RegisteredObject2. Write a Python function decodebase64docref to
a. loop through the FHIR bundle

Hi Community,

👉 Can FHIR also serve as input for operational management? 👈

In my previous article, I introduced the FHIR Data Explorer, a proof-of-concept application that connects InterSystems IRIS, Python, and Ollama to enable semantic search and visualization over healthcare data in FHIR format, a project currently participating in the InterSystems External Language Contest.
In this follow-up, we’ll see how I integrated Ollama for generating patient history summaries directly from structured FHIR data stored in IRIS, using lightweight local language models (LLMs) such as Llama 3.2:1B or Gemma 2:2B.
The goal was to build a completely local AI pipeline that can extract, format, and narrate patient histories while keeping data private and under full control.
All patient data used in this demo comes from FHIR bundles, which were parsed and loaded into IRIS via the IRIStool module. This approach makes it straightforward to query, transform, and vectorize healthcare data using familiar pandas operations in Python. If you’re curious about how I built this integration, check out my previous article Building a FHIR Vector Repository with InterSystems IRIS and Python through the IRIStool module.
Both IRIStool and FHIR Data Explorer are available on the InterSystems Open Exchange — and part of my contest submissions. If you find them useful, please consider voting for them!

Hi Community,
In traditional InterSystems SQL, I can use the %NOINDEX keyword during a bulk INSERT to improve performance and then run BUILD INDEX %ALL afterward to populate the indices.
I am looking to implement a similar strategy for an InterSystems FHIR Server.
%NOINDEX)?Thank you!
You may notice when upgrading to IRIS For Health from 2024.1 to 2024.2+ (2025.1, 2026.1, etc.) that where you were previously accessing your FHIR Portal you are now receiving Not Found.
In a previous article, I presented the IRIStool module, which seamlessly integrates the pandas Python library with the IRIS database. Now, I'm explaining how we can use IRIStool to leverage InterSystems IRIS as a foundation for intelligent, semantic search over healthcare data in FHIR format.
This article covers what I did to create the database for another of my projects, the FHIR Data Explorer. Both projects are candidates in the current InterSystems contest, so please vote for them if you find them useful.
You can find them at the Open Exchange:

I’m excited to share the project I’ve submitted to the current InterSystems .Net, Java, Python, and JavaScript Contest — it’s called FHIR Data Explorer with Hybrid Search and AI Summaries, and you can find it on the InterSystems Open Exchange and on my GitHub page.

In v2026.1 we introduced support for a more robust and real-life secure authorization for your FHIR endpoints.
This is achieved by using SMART on FHIR v2 fine-grained scopes.

Hi,
I'm pretty sure I'm not the first one to encounter this, so please share your solution
I'm trying to load a package with 2 dependencies, one of them has 5 dependencies..
is there a better tool / script / wizard for that?
I am working on setting up OAUTH with FHIR and Microsoft Entra. I have configured the Client and configured it in the FHIR Server successfully. However, I get 401 when authenticating with a token. Looking at ^ISCLOG I see:
^ISCLOG("Data",9,0)="accessToken=<jwt token>, scope=, aud="
^ISCLOG("Data",10)=$lb(3,"OAuth2","[OAuth2.ServerDefinition:ValidateJWT]","171430","%SYS","2026-04-28 17:41:25.305549397","OAuth2.ServerDefinition.1","","zwKKakZZZx2")
^ISCLOG("Data",10,0)="JWT valid? sc=1"
^ISCLOG("Data",11)=$lb(3,"HSFHIRServer","[HS.FHIRServer.
In v2026.2 (currently available as a Developer Preview), we are adding a feature that can help in a FHIR Endpoint SMART/OAuth authorization - more out-of-the-box flexibility in audience value validation.
Hi, Community!
Are you gathering data for clinical research? See how InterSystems OMOP can help streamline your data preparation:
A very important feature for HL7 FHIR has been introduced with the release of v2026.1 - the support for SMART on FHIR v2 fine-grained granular Scopes.
This enables you to be much stricter and more accurate in the access you provide to the data in your FHIR repository.
Part of this new support is to refuse requests that don't match the scopes, but an even more interesting ability is to filter the results according to the provided scopes.
The 2026.1 release of InterSystems IRIS® data platform, InterSystems IRIS® for Health, and InterSystems Health Connect™ is now Generally Available (GA). This is an Extended Maintenance (EM) release.

Hi Community,
An error occurs during the analysis process in the FHIR SQL Builder. How can I identify the exact cause of the error?
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##class%NewIf I change the response code to 422, the calling app doesn't get the OperationOutcome. Instead I get
The custom error module does not recognize this error.
Do I need to implement a custom error?
FHIR (Fast Healthcare Interoperability Resources) is the modern standard for storing and exchanging clinical data. But once your data is in a FHIR server, how do you actually explore it? FHIR data is stored as JSON — powerful, but not practical to read directly. I wanted a tool where you could click on a patient, see their conditions, medications, lab results, and more — in a clean, readable format. So I built the FHIR Patient Viewer.
The app runs entirely in Docker and connects directly to an InterSystems IRIS for Health FHIR server.
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.
Earlier this year, I set about creating kit to introduce young techy folk at a Health Tech hackathon to using InterSystems IRIS for health, particularly focusing on using FHIR and vector search.
I wanted to publish this to the developer community because the tutorials included in the kit make a great introduction to using FHIR and to building a basic RAG system in IRIS.
