BroadSea - Core OHDSI Walkthrough with InterSystems OMOP

Hi everyone,

I'm currently seeking a new position related to InterSystems technologies. My major skill is app integration and data flow development on the InterSystems IRIS platform (Interoperability). I develop high-load, mission-critical software. My coding background on Cache ObjectScript includes hundreds of data flows, thousands of Production business hosts, dozens of APIs, and other solutions on InterSystems IRIS. I worked to integrate such applications as SAP S/4HANA, Oracle Siebel, SAP Commerce Cloud, many custom apps, and all that can be integrated. I have also gained experience in various areas, including SQL, Java, Docker, IRIS administration, Apache Kafka, and Flutter (Dart).

My problem was separating HL7 messages by message type.  I had to create multiple File Operations.  So I with custom code I am able to use 1 File Adapter for 1 interface and multiple message types.  I did experiment pulling the MSH 4 out of the raw content to further access dynamic information, but that may open a need for more robust error checking / lookup default actions.

Using the recommended naming convention of "To_FILE_<IntegrationName>"

I decided to use a generic file name and path in the default settings.

I created a custom class that extended the EnsLib.File.

I used to mannually test objectscript code in InterSystems Studio.  Does anyone know how to do this is VS Code?

We are excited to announce the general availability of JediSoft IRISsync®, our new synchronization and comparison solution built on InterSystems IRIS technology.  IRISsync makes it easy to synchronize and compare IRIS instances.

IRISsync was voted runner-up in the "Most Likely to Use" category at InterSystems READY 2025 Demos and Drinks.

A huge thanks to everyone who supported us — we’re thrilled to see IRISsync resonating with the InterSystems user community!

IRISsync provides clear visibility into differences between environments.

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.

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.

Hi,

Is there any way to recover management portal _system user password?

Hi Community,

The new video from Global Summit 2019 is available on InterSystems Developers YouTube:

⏯ 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?

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.

Hi Everyone,

So after @Ariel.

InterSystems FAQ rubric

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 codes
      if (Stcount<1) {
          throw ##class(%Exception.General).%New("User-defined error", "5001", "location", "Data at location error")
          // User-created errors are 5001 and above
      }
    }
    catch ex
    {
      write "Errors #", ex.Code, ": ", ex.Name, " : ", ex.

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

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.

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.

InterSystems FAQ rubric

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.

..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?

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 = $SYSTEMSQL.Schema.

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.
