#InterSystems IRIS for Health

I am available to engage on projects as an Iris Healthcare Consultant, leveraging over 20 years of extensive experience in IT architecture with a special focus on Intersystems IRIS and Health Share solutions.

My expertise includes leading critical NHS projects in the UK as well as  building SaaS solution designed to enhance revenue cycle management and facilitate integration between hospitals and doctors in the US.

In the last article we presented the architecture of our SMART On FHIR project, so it's time to get down to business and start configuring all the elements that we are going to need.

We will first start with Auth0.

AUTH0 configuration

We will start by creating an Auth0 account with a valid email, once registered we will have to create our first application, and we will do it from the menu on the left:

In our example, the application will be of the Single Page Web Application type as it is an application developed in Angular 16. We select this option and click Create.

I am trying to create a HS.FHIR.DTL.vR4.Model.Resource.Encounter message based on a conversion of HS.FHIRServer.Interop.Response QuickStream to a JSON %Dynamic Object. 

When I try to send the HS.FHIR.DTL.vR4.Model.Resource.Encounter onto the Router

1. it is not showing up as a Defined Message Class to Route the message back to the SourceConfigName of the Request message that initialized the FHIR query
2. I keep getting "ERROR <Ens>ErrBPTerminated: Terminating BP EPIC.FHIR.Process # due to error: ERROR #5002: ObjectScript error: <SUBSCRIPT>%SaveData+29 ^Ens.MessageHeader.1 ^Ens.

I have this response, which is a FHIR location resource in a bundle. I would like to load the entry(0).resource into a context property defined as HS.FHIR.DTL.vR4.Model.Resource.Location so I can use it as a source in a DTL.  Any help would be greatly appreciated.  Thanks. 

{"entry":[{"fullUrl":"https://dev-api.hosp.org/idkl/fhir/r4/v1/Location/ATH-1375-PRV-a-1375.D…","resource":{"extension":[{"url":"https://api.hosp.org/idkl/extensions/StructureDefinition/is-messaging-e…","valueBoolean":true}],"id":"ATH-1375-PRV-a-1375.

When running a sql insert query with CONVERT('datetime', '2023-12-12 11:27:00',120) in an insert statement into a table this works on one server and not the other. 

i.e.

In message bank how do you search within XML? XML is imported on message bank so that side is ok as can see it like below

On source system message viewer finds message

On Message bank it doesn't 

More basic queries using the MessageHeader will work so the filters do work just must not be using the right one (if it is possible) to query the XML message 

I have this code and I need to send 

Set tRequest= ##class(Testing.Messages.GatewayCreateFacilityRequest).%New()

Set tRequest.facilityCode ="VINUSE"

 Set tResponse = ##class(Testing.Messages.GatewayCreateFacilityResponse).%New()

need to send a request to a new server:

Server: ECR10 

Namespace: ECR

Business Service: Healthix.Common.Verato.Gateway.Service.HubQueryService

set tResponse = ##class(Testing.Gateway.Service.HubQueryService).%New().CreateFacility(tRequest)

How do I add code to send it to the ECR10 server?

I thought I knew how to return a Response from a Business Process back to the Source Config Name, but I guess not. 

I am working on a Proof of Concept, that the Request Message Class would determine a "Route" within a Business Process to make a FHIR call (search, read) to our External FHIR repository, and return back the HS.FHIR.DTL.vR4.Model.Resource.xxxxxxx as a Response to the Source Config Name.

I have the FHIR part working, however now that I have the data in the form of HS.FHIR.DTL.vR4.Model.Resource.

Instead of building a BP to execute stored procedures just to insert the data, I figured I would give Linked Stored Procedures a try since all I need to do is insert the data. I have proved in our MS SQL Development environment that it is possible, so I through I could just repoint the Linked Stored Procedure 

set hdbc=$$GetJConnection^%apiGTW("xxxxx")

to the test environment. But when I made the changed in VSCode and compiled the Stored Procedure disappeared from the SQL view in the Management Portal.

So can we not simply update the connection string to point to a different MS SQL Connection?

I have a requirement where in I had to read a HL7 message string ( which is a String )
from a SQL TBL to my Business Service.
and I need to convert that string to EnsLib.HL7.Message format and traverse through the PID segment.

I need  some inputs please.

I have challenged to create a bot application using Azure Bot that can retrieve and post data to IRIS for Health.

A patient's data has already been registered in the FHIR repository of IRIS for Health.

The patient's MRN is 1001. His name is Taro Yamada. (in Japanese :山田 太郎)

This bot can post new pulse oximeter readings as an observation resource linked to the patient.

For practical reasons, it may be desirable that after a Linux server restart, the IRIS instance is automatically started. 

Below you will find the steps to follow to automate the startup of IRIS during a reboot of the Linux server, via systemd :

1. Create an iris.service file in /etc/systemd/system/iris.service containing the following information

[Unit]
Description=InterSystems IRIS Data Platform
After=network.

The following code downloads https://www.intersystems.com/assets/intersystems-logo.png and saves the file as c:\temp\test.png.

You need to define an SSL configuration called SSLTEST before executing this code

ClassMethod download() As %Status
{
    Set sc = $$$OK
    Set httprequest=##class(%Net.HttpRequest).%New()
    set httprequest.Port = 443
    set httprequest.Https = 1
    set httprequest.SSLConfiguration = "SSLTEST"
    Set httprequest.Server="www.intersystems.com"
    Do httprequest.Get("/assets/intersystems-logo.png")
    Set httpresponse=httprequest.

Hi,

Can we write message in the messages.log file ?

Thanks

I've been trying unsuccessfully to use a parameter function within a routing rule. I can see the function %GetParameter available in the WYSIWIG rule editor, but I cannot seem to get the inputs for it correct, e.g.

Which gives the error

I have also tried unsuccessfully in code

Is what I am doing possible, and I have a syntax issue? Or is getting a parameter like this not something that can be done in a class of type Ens.Rule.Definition
Thanks

InterSystems IRIS Adaptive Analytics version 2024.1.3 is now available from the InterSystems Software Distribution  page.  This release includes AtScale 2024.1.3, and an updated User Defined Aggregate Function (UDAF) file.  This release includes and the following new modeling and BI capabilities:

• Formatting of calculation output based on on the field input rather than just the format defined on the calculation.  This is particularly useful for calculations that can't have a standard output format, such as year-over-year growth in dollars, euros, or time.

Hey,

since our instance of iris is just utilized during working hours, I would like to simply copy all data via FTP from the server to a NAS during the night.

Are there reasons against this approach?

Are there batch examples of how to stop and start the database?

Thank you in advance!

Accessing an Azure cloud storage to upload/download blobs is quite easy using the designated %Net.Cloud.Storage.Client class API methods, or using the EnsLib.CloudStorage.* inbound/outbound adaptors.

Note that you'll need to have the %JavaServer External Language Server up and running to use the cloud storage API or adaptors, since they both use the PEX framework using the Java Server.

I am leveraging the cloud storage adaptor to upload objects to an S3 bucket.  I now need to add Tags to the object, but I don't see any mechanism within IRIS to allow adding of Tags.

Is that functionality currently available?

Wondering if gherkin (or even cucumber) can be used with IRIS software for testing?

Temporary globals stored in the IRISTEMP/CACHETEMP databases are used when a process does not need to store data indefinitely, but requires the powerful performance of globals. The IRISTEMP/CACHETEMP databases are not journaled, so using temporary globals does not create journal files.

The system uses the IRISTEMP/CACHETEMP databases for temporary storage and are available to users for the same.

For more information about temporary globals and the IRISTEMP database, see the following document:

Alert: Database Corruption with Multi-Volume Databases after Truncation

InterSystems has corrected a defect that can cause database corruption or <DISKHARD> errors with multi-volume databases under extremely rare circumstances. Only databases that have been truncated are at risk.

The defect exists in the following products and any InterSystems offerings based on them:

• InterSystems IRIS® – 2024.1, 2024.1.1, and 2024.2
• InterSystems IRIS® for Health – 2024.1, 2024.1.1, and 2024.2
• HealthShare® Health Connect – 2024.1, 2024.1.1, and 2024.

Hi fellows,

How can I query all Patient SDA from a Regestry and export to file? Exist some table when I can query all Patient?

To export, I found the class HS.SDA3.QuickXML and method ToQuickXMLStream, but I can't find a table where query all Patient, by update date for example.

Thanks in advanced!

The first developer preview of InterSystems IRIS 2024.3 and InterSystems IRIS for Health 2024.3 has been posted to the WRC developer preview site.  Containers can be found on our container registry and are tagged latest-preview.

This is a very early build in the release cycle and there aren’t any “highlight” worthy features that are complete.  They’ll start to arrive in future preview releases.

Initial documentation can be found at these links below.

Hello,

I have a slight issue that's causing me some inconvenience when using the rule editor within Microsoft Edge (Version 126.0.2592.81).

Whenever I try to load up any ruleset, the ruleset displays an unhappy face like this:

This has only recently started, when opening up the rule editor in another browser e.g. Chrome, the problem disappears.

I've tried to remedy the situation by resetting Edge, Updating Edge Version, Clearing Cache/Cookies etc. but nothing seems to fix it.

I'm trying to use the EnsLib.SQL.Operation.GenericOperation component in a production to read a column from a Redshift table that is set up as VARCHAR(65535) and am getting the following error.  

An error was received : ERROR #5023: Remote Gateway Error: JDBC Gateway getClob(0,1) errorRemote JDBC error: Cannot convert the column of type VARCHAR to requested type long..

The query I'm using is a simple 'SELECT column_name FROM table_name'.

I was looking for an easier way to build the FHIR Query String, given the Record Map request that is passed into the DTL.

I built this Function, but when I run a message through it, my Query String that is passed back into the DTL is a Reference Pointer and not the String I am looking for.

What is wrong in this snippet??

Have a question about the new Rule Editor within 2024.1... How are you able to edit the Target, it shows greyed out and when I click on the field it does not allow me to edit the field.

I would like to understand before I give my team a presentation tomorrow about if we should upgrade or not. Thanks

A nice feature that we recently added to version 2.12.6 of the VS Code ObjectScript extension is controlled by this new setting:

objectscript.serverSourceControl.respectEditableStatus

When set true in JSON, or checked in the Settings Editor, a server-side file will be read-only if the source control class for the namespace reports that it is not editable.

This option may be of particular interest to users of our Deltanji source control product, particularly when used in combination with the Deltanji extension for VS Code.
