Using OpenEHR with InterSystems IRIS

Occasionally. we get questions about using OpenEHR with InterSystems. Typically, these discussions focus on why and how an organization wants to implement OpenEHR in building applications. Here’s a brief guide:

A benefit of using Doxygenerate is that Doxygen does more than just HTML output. Tweak the Doxyfile that tells Doxygen what to do and you can easily create a PDF. Our example MARINA application yielded a 524-page PDF. Here's what page 94 looks like:

Hi Community,

I have been walking through this with a few team members and as such I thought there might be others out there who could use it, especially if you work with HL7 & Ensemble/HealthConnect/HealthShare and never venture out past the Interoperability section.

Hi Everyone,

So after @Ariel Glikman posted a custom operation example, I'm stuck on another dilemma, and here it is:

FHIR Server

A FHIR Server is a software application that implements the FHIR (Fast Healthcare Interoperability Resources) standard, enabling healthcare systems to store, access, exchange, and manage healthcare data in a standardized manner.

Intersystems IRIS can store and retrieve the following FHIR resources:

• Resource Repository – IRIS Native FHIR server can effortlessly store the FHIR bundles/resources directly in the FHIR repository.
• FHIR Facade - the FHIR facade layer is a software architecture pattern used to expose a FHIR-compliant API on top of an existing one (often non-FHIR). It also streamlines the healthcare data system, including an electronic health record (EHR), legacy database, or HL7 v2 message store, without requiring the migration of all data into a FHIR-native system.

What is FHIR?

Fast Healthcare Interoperability Resources (FHIR) is a standardized framework created by HL7 International to facilitate the exchange of healthcare data in a flexible, developer-friendly, and modern way. It leverages contemporary web technologies to ensure seamless integration and communication across various healthcare systems.

Often times when working with FHIR data, for example with IRIS For Health, you'll find it useful to create a custom FHIR operation. The FHIR Standard comes with a set of defined operations (such as $everything) but a custom operation comes in handy when you need to create some extra functionality that goes beyond the set of standard FHIR operations.

We have a task that runs objectscript code to load data into a linked external table. After upgrading from 2024.1 to 2025.1, the load is throwing an error, with error code -400, and no error message. The data DOES get loaded into the external table in its entirety, so with no meaningful error message, its hard to determine what the issue is. The result is the same with and without the USING clause, so don't let that confuse you. We have logs of this statement succeeding before upgrade, and were able to get this statement to work in our production environment, which is still on version 2

..Contains(source.{ORCgrp(x1).OBRuniongrp.NTEi2(x2):Comment(x3)},"(")&&..Matches(source.{ORCgrp(x1).OBRuniongrp.NTEi2(x2):Comment(x3)},"^[A-Z][0-9][0-9]$")

I want to do this to match strings such as X98. Community AI tells me this is correct but I get an error in testing. Specifically, this is the part causing the error;
..Matches(source.{ORCgrp(x1).OBRuniongrp.NTEi2(x2):Comment(x3)},"^[A-Z][0-9][0-9]$")

What do I need to change?

I created a Custom Search Table that extends EnsLib.HL7.Search Table. I saved, compiled, and rebuilt the index however when I go into Message Search to try to use the Search Table, within the conditions the proper fields are not showing up that was defined. It is showing the fields from EnsLib.HL7.SearchTable. I did a build index on both EnsLib.HL7.SearchTable and OSU.HL7.SearchTable.

⏯️ Health Evolve: Transforming Unstructured Data

Did you know that 80% of healthcare data is stuck in unstructured formats such as fax? If you take a walk down to Mass General in Boston, you'll literally see a state-of-the-art MRI machine next to a fax machine. Healthcare keeps building incredible new technology but can't let go of legacy technology. We call this the "legacy modernization paradox". This short film follows a care manager at Blue Plan who spends her days doing chart reviews, reading faxes line-by-line, struggling to provide her members the care they need. Everything changes when Blue Plan pilots InterSystems Health Evolve, a solution that transforms her faxes into machine-readable FHIR data ready for AI and analysis. To access our fully working Text-to-FHIR prototype, visit HealthEvolve.de.

I had a need for a Filter, but did not want to recreate the wheel by creating another Data Lookup Table, so instead I created a Linked Table that points to a MS SQL Table outside of IRIS.

Once I had the Linked Table, I created a Class Method Function that would query the Linked Table and return a 1 if a result came back.

IAM - InterSystems API Manager is a great tool for monitoring your traffic. If you are trying to use it in your Kubernetes cluster you may have tried doing a deployment similar to this one:
