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:

• InterSystems is focused on interoperability:  we prioritize interoperability through standards such as HL7, IHE, DICOM, and ISO. In our experience, no single standard addresses all the needs of complex healthcare data. Thus, we recommend that any implementation of OpenEHR be evaluated in conjunction with these standards and an analysis of which of

I would like to learn about the binary and document reference FHIR Resources. For the PDF data stored in those resources. But I think Binary Resource for the Document PDF stored in FHIR, so this resource is best for it. So sometimes Large PDF 15-page (~35md) data converts into base64 then data length is ~50 lac charecters length of base64binary data. this data store in Binary Resource on data field https://www.hl7.org/fhir/R4/binary.html follow this url this resource used in my case. so it's support the 50 lac charecter of the base64 length? This resource can be Insert into IRIS?

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:

You can browse the whole file here.

In the screenshot above, notice how we only get details of the superclass that is part of the app (AuditHistory). The primary superclass, %Library.SerialObject, is shown faded and with no details of what BankDetails inherits from it.

With another tweak to the Doxyfile we can show full inheritance detail in a 586-pag

⏯ Reintroducing the Operational Data Store

The healthcare technology market is in strong evolution. Gartner's wave chart for healthcare technologies demonstrates what these technologies are, very well reflected by healthcare.digital. I call this HealthTech See:

These technologies can use InterSystems technologies (ISC Health Tech), see:

Consent Management uses InterSystems Healthshare Stack to do MPI and consent management, see:

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. 

First, I would like to establish that this is an extension of the already established documentation on importing and exporting SQL data found here: https://docs.intersystems.com/iris20241/csp/docbook/DocBook.UI.Page.cls?KEY=GSQL_impexp#GSQL_impexp_import

We currently have Business Operation that we built to use the EnsLib.SQL.OutboundAdapter so we can make Microsoft SQL Server Stored Procedure calls. The BO is attached to a Java Gateway Service.

Some of our MS SQL Databases have moved from being OnPrem to Azure Cloud. We have started seeing where we are receiving errors on the BO saying that we cannot connect to the Azure Database, but we never receive a Disconnect from the Azure Database.

Once this happens it seems that the Java Gateway still thinks the connection is opened, and we have to Stop/Start the Java Gateway to get the connection to

Hi Everyone,

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

1. I might have different patients with the same business identifier
2. Each patient (logical) might have several resources like Observations, Conditions and Tasks (there are other type but they are not part of the issue)
3. Tasks are a representation of something called "Morbidity", it's a presumed illness but not a validated condition
   1. Tasks are created according to observations and/or conditions and the task hold a reference to those resources
   2. A resource such as Observation /

If you want to raise an arbitrary custom error in a TRY block, you can pass an exception with a throw as follows. In the following example, a custom error is raised if Stcount is less than 1.

Class User.Test
{

ClassMethod ExceptionTest()
 {
    try
    {
      // : some codesif (Stcount<1) {
          throw##class(%Exception.General).%New("User-defined error", "5001", "location", "Data at location error")
          // User-created errors are 5001 and above

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.

I am trying to help another group within our organization access a SQL Table that I have created to populate Epic Department Data within our environment and came across the ability to use SQL Seach REST Interface using iKnow.

However, I am having issues trying to get it to work via POSTMAN before I hand off the solution...

the POST URL... https://<servername>/api/iKnow/latest/TESTCLIN/table/osuwmc_Epic_Clarity.DepartmentMaster/search

where osuwmc_Epic_Clarity.DepartmentMaster is the table

In the body...

{"query":SELECT ID, Abbr, Name, ExternalName, PhoneNumber, ApptPhone, FaxNumber, Address1,

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. The docs take you step-by-step (though this comment may be helpful to those of you just getting started).One thing I would highlight, purely for aesthetic purposes, is how to syntactically name your function such that you can call it with hyphens.

Professional Grade FHIR® to OMOP Transformation

Lets zero in on the use of the word professional and put it into some context.  It was written by industry experts who wrapped it up in a fee based service with support and some guardrails around flexible options to contribute to its behavior.  I feel its an important distinction to either an open or home grown solution (though it may do the same thing) to consider it to scale or provide mission critical value on the other side of it. The OHDSI community has an entire competency around the subject of ETL to the OMOP database,  WhiteRabbit for

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.

Mirroring only synchronizes database files.

To synchronize other files required for your application (CSP files, images, documents, etc.) between the two servers that make up the mirror set follow one of the approaches:

1. Place those files on a shared disk by introducing a NAS or similar device
2. Or use file sync software to synchronize files between two servers.

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;

In InterSystems IRIS, you can create linked tables using commands, instead of using System Explorer > SQL > Wizard > Linked Tables in the Management Portal:

To create a linked table, use the CreateLinkedTable method of the %SYSTEM.SQL.Schema class. See the class reference for details.

To execute it, follow these steps:

set sc = $SYSTEM.SQL.Schema.CreateLinkedTable("<dsn>","<Schema>","<Table>","<primaryKeys>","<localClass>","<localTable>","")

/// 1st argument: dsn - SQL Gateway connection name/// 2nd argument: Schema - Source schema name/// 3rd argument: Table -

⏯️ 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.

InterSystems IRIS interoperability production development involves using or writing various types of components. They include services (which handle incoming data), processes (which deal with the data flow and logic), and operations (which manage outgoing data or requests). Messages flowing through those components constantly require being adapted to consuming applications. Therefore,Data transformations are by far the most common component in interoperability productions.

In the early stages of data transformation development, thetest tool from the Management Portal becomes quite handy.

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.

ClassMethod CheckPDMProviderType(pInput As%String) As%Boolean
{
    set ExtDisplay = ""
 		&sql(SELECT SecurityGroup_k INTO :ExtDisplay

InterSystems FAQ rubric

There is data, such as execution log data, that you do not want to return to its previous state even if a rollback occurs during a transaction. The above requirement can be met by placing that data in the IRISTEMP database, which will not be rolled back.

Temporary Globals and the IRISTEMP Database

By mapping the table entities you do not want to roll back to this database, you can retain the information after the rollback.

However, the contents of this database will be cleared when IRIS is restarted, so if you want to keep it permanently, you will need to copy it to a
