Hi community,

A few weeks ago I published an API accelerator call Memoria, Is a very simple way to minimize the time and network traffic to and end-point, I hope could be useful.

Hello, good morning, thank you so much for reading this question. ☺️🙂👍

We are developing a code to get information about our Production's items: services, processes and operations.

We know we can get various configurations of a given item: Category, Port, Enabled...

But we wonder how we could get the date time of the last mesage (most recent) received in an item.

To give a code snippet a small section of the code we have developed (and tested), it looks like:

[...]

For i=1:1:tProduction.Items.Count() {
    #dim item as Ens.Config.Item
    set item = tProduction.

Description

Is anyone using DICOM Interoperability in IRIS for Health configured in Mirror?

I'm asking because I'm not sure how to handle where the DICOM messages are stored.

For some reason DICOM use the filesystem to store raw messages, the directory used can be configured in the StorageLocation production settings, obviously this is a big issue if/when a mirror failover occur.

Unfortunately in IRIS it's not possible to change the DICOM storage from file stream to global stream.

Has anyone came across this issue?

Hello Everyone,

The Certification team of InterSystems Learning Services is developing two new HealthShare Unified Care Record certification exams, and we are reaching out to our community for feedback that will help us evaluate and establish the contents of the exams.  Please note that these exams will replace our HealthShare Unified Care Record Technical Specialist exam that we plan to retire in January 2026. Certifications earned in this technology before the exam’s retirement will remain valid for five years from the date of achievement.

How do I provide my input?

IRIS and Ensemble are designed to act as an ESB/EAI. This mean they are build to process lots of small messages.

But some times, in real life we have to use them as ETL. The down side is not that they can't do so, but it can take a long time to process millions of row at once.

To improve performance, I have created a new SQLOutboundAdaptor who only works with JDBC.

BatchSqlOutboundAdapter

Extend EnsLib.SQL.OutboundAdapter to add batch batch and fetch support on JDBC connection.

Benchmark

Benchmarks released on Postgres 11.2 with 1 000 000 rows fetched and 100 000 rows inserted on 2 columns.

You know that feeling when you get your blood test results and it all looks like Greek? That's the problem FHIRInsight is here to solve. It started with the idea that medical data shouldn't be scary or confusing – it should be something we can all use. Blood tests are incredibly common for checking our health, but let's be honest, understanding them is tough for most folks, and sometimes even for medical staff who don't specialize in lab work. FHIRInsight wants to make that whole process easier and the information more actionable.

Hi Developers!

We are happy to present the bonuses page for the applications submitted to the FHIR and Digital Health Interoperability Contest 2025!

See the results below.

IRIS supports CCDA and FHIR transformations out-of-the-box, yet the ability to access and view those features requires considerable setup time and product knowledge. The IRIS Interop DevTools application was designed to bridge that gap, allowing implementers to immediately jump in and view the built-in transformation capabilities of the product.

Hi Community,
In this article, I will introduce my application iris-fhir-bridge 
IRIS-FHIR-Bridge is a robust interoperability engine built on InterSystems IRIS for Health, designed to transform healthcare data across multiple formats into FHIR and vice versa. It leverages the InterSystems FHIR Object Model (HS.FHIRModel.R4.*) to enable smooth data standardization and exchange across modern and legacy healthcare systems.

Profiling CCD Documents with LEAD North’s CCD Data Profiler
Ever opened a CCD and been greeted by a wall of tangled XML? You’re not alone. Despite being a core format for clinical data exchange, CCD's are notoriously dense, verbose, and unfriendly to the human eye. For developers and analysts trying to validate their structure or extract meaningful insights, navigating these documents can feel more like archaeology than engineering.

Let me introduce you to FHIRCraft, a lightweight tool to generate synthetic FHIR resources.

Now, you might be thinking:
“But wait — doesn’t Synthea already do that, and with tons of resources?”
Exactly — and that’s precisely why I created this app.

FHIRCraft is designed to generate simpler, smaller, and more focused FHIR resources. Unlike Synthea, it doesn’t aim to simulate entire patient histories or clinical workflows. Instead, it helps when you’re just getting started with FHIR — when you want to test things incrementally, or explore how specific resources behave in isolation.

Hi Developers,

We are happy to announce the new InterSystems online programming contest dedicated to all things health-related:

🏆 InterSystems FHIR and Digital Health Interoperability Contest 🏆

Duration: May 12 - June 1, 2025

Prize pool: $12,000

After we rolled out a new cointainer based on containers.intersystems.com/intersystems/irishealth:2023.1 this week, we suddenly noticed that our FHIR Repository started responding with an Error 500. This turns out to be caused by PROTECT violations on the new HSSYSLOCALTEMP namespace and database used by this version of the IRIS for Health FHIR components.

The trick to solve that is to add the "%DB_HSSYSLOCALTEMP" to the Web Application(s) that handle FHIR Requests. You can script that by running the following Class method in the namespace(s) that define these Web Applications:

do ##class(HS.

We’re issuing a point release for InterSystems IRIS, IRIS for Health, and Health Connect 2025.1 — version 2025.1.0.225.1 — to address a critical interoperability issue affecting users who leverage System Default Setting enabled business hosts.

What’s the issue?
In certain configurations where a Business Host is marked as System Default Setting enabled, applying new settings via the UI may incorrectly indicate that changes were applied, even though the necessary restart did not occur.

I'm creating a Business Process that:

1. Transforms one object into another using DTL
2. Sends this object to an operation
3. Transform the object obtained in first point into another one using DTL
4. Sends the second object to an operation

The Business Process is created with BPL, and objects are stored in BP context. When I execute this Process, in the 3rd point the object obtained in first transformation doesn't exist. It's empty.

In the previous article we have reviewed how to install our EMPI in standalone, so we are ready to start the basic configuration of our EMPI.

First of all we have to do an initial basic configuration, we can access to the configuration from the Configuration menu of our Registry.

Selecting that option will allow to us to edit the basic configuration table of the Registry:

In this menu we have to add the following parameters and update the value of one of them:

Business Process is adding control characters.

Input HL7 shows no control characters in Notepad ++

Hi Developers!

Hi,

I've been working on a very basic Interoperability production in my computer. I followed one of the examples in the courses and created a TEST.FileRouterRoutingRule, but when trying to edit this rule, it takes me to the Rule Editor Login Page, where I can't get in (Not even with the _SYSTEM credentials) - Is this functionality unavailable in the community edition?

The amazing Iris-nator has arrived in town.

He knows what you think, with just a few questions he is able to guess the character you have thought of.

Do you dare?

One of the challenges of creating a DICOM message is how to implement putting data in the correct place. Part of it is by inserting the data in the specific DICOM tags, while the other is to insert binary data such as a picture - In this article I will explain both.

To create a DICOM message, you can either use the  EnsLib.DICOM.File class (to create a DICOM file) or the  EnsLib.DICOM.Document class (to create a message that can be sent to PACS directly). In either case, the SetValueAt method will allow you to add your data to the DICOM tags.

Has anybody tried to extend the Menu on Management Portal? I like to add a new page or a dashboard that will be created soon to the Management Portal and allow others to use it also. I understand there are risks that I could lose things during an upgrade. I am okay with that. Does InterSystems support such an effort?

The InterSystems IRIS is a great data platform and it is met the current features required by the market. In this article, you see the top 10:

Note: this list was updated because many features are added to IRIS in last 3 years (thanks @Kristina.

Hi all,

I can't find the list of business host setting sections and (crucially) how to refer to them in the SETTINGS parameter, as marked in purple here:

Parameter SETTINGS = "MySetting:Basic";

Does anyone know where this list lives?

I added extra OBX segments and I need to renumber OBX 4 so they are sequential.

For my hundredth article on the Developer Community, I wanted to present something practical, so here's a comprehensive implementation of the GPG Interoperability Adapter for InterSystems IRIS.

Every so often, I would encounter a request for some GPG support, so I had several code samples written for a while, and I thought to combine all of them and add missing GPG functionality for a fairly complete coverage. That said, this Business Operation primarily covers data actions, skipping management actions such as key generation, export, and retrieval as they are usually one-off and performed manually anyways. However, this implementation does support key imports for obvious reasons. Well, let's get into it.

One of the pain points for maintaining HL7 interfaces is the need to run a reliable regression test upon deployment to new environments and after upgrades. The %UnitTest class allows unit tests to be created and packaged alongside interface code. Test data can also be maintained within the unit test class, allowing for quick and easily repeatable smoke-testing and regression testing.

##Resources:

• Standard %UnitTest class
