InterSystems IRIS is a Complete Data Platform
InterSystems IRIS gives you everything you need to capture, share, understand, and act upon your organization’s most valuable asset – your data.
As a complete platform, InterSystems IRIS eliminates the need to integrate multiple development technologies. Applications require less code, fewer system resources, and less maintenance.

My intention is to show how simple it is to generate a lookup table taking into account the information received in our HL7 messaging. The HL7 message lookup table provided by IRIS is certainly sufficient for most of the searches we want to perform, but we always have that special field in our HIS, LIS, RIS, etc. that we'd like to search by. But that's in a segment outside of that lookup table. That field forces us to generate a specific search using the expanded search criteria.

Hi all,

We're developing a medical appointment app that connects doctors' schedules to an appointment provider.

The provider is returning us the appointment in the following format:

Thu Jul 03 08:20:00 CEST 2025

It means, 03 july 2025 at 08:20:00 Central European Summer Time (UTC+2)

But we need the following format:

2025-07-03 08:20:00+02:00

Is there any option to convert zone time code (CEST) to a UTC+x ?

How to convert zone time code (CEST, CET, ET, EDT, etc..) in its zone time in UTC (UTC+2, UTC+1, UTC-5, etc..) ?

I have created a New Database/Namespace within our TEST environment on both the Primary and Backup of the mirror. When I go to create the database/namespace on the DR node I am getting "Cannot open file '/ensemble/TEST/iris.cpf_...." while the cpf file that it references does not exist. Anyone have any clue to why this might be happening?

I am making a FHIR request against Epic, in when I get the Response back using "fromDao" I am extracting the stream into HS.FHIRModel.R4.Patient. However, the patient's name comes back as name within a list that references HS.FHIRModel.R4.SeqOfHumanName.

  • How do I extract the name from HS.FHIRModel.R4.SeqOfHumanName?
  • Do I have to then do another "fromDao" to pull the list into string format?
  • How do I navigate around the lists that are in a FHIRModel response, to extract the string values?

Thank you community for translating an earlier article into Portuguese.
Am returning the favor with a new release of Pattern Match Workbench demo app.

Added support for Portuguese.

The labels, buttons, feedback messages and help-text for user interface are updated.

Pattern Descriptions can be requested for the new language.

I was wondering if anyone had a way to automate creating the Query String for a FHIR Request?

Using HS.FHIRServer.Interop.Request in my development I have to specify the following...

I was wondering.... if my source had variable number of fields if there was a way to automate the build for the QueryString when doing a Patient Search?

In IRIS, every time a request need to be processed, a specific IRIS process (IRISDB.EXE) need to be assigned to handle that request.

If there is no spare IRIS process at that time, process will need to be created (and later destroyed). On some Windows systems (especially with security/antimalware solutions being active) creating new processes can be slow, which can results in delays during peak times (due to inrush of requests).
