InterSystems IRIS for Health™ is the world’s first and only data platform engineered specifically for the rapid development of healthcare applications to manage the world’s most critical data. It includes powerful out-of-the-box features: transaction processing and analytics, an extensible healthcare data model, FHIR-based solution development, support for healthcare interoperability standards, and more. All enabling developers to realize value and build breakthrough applications, fast. Learn more.

Hi noble devs!

Just building a simple frontend->JSON->IRIS backend story, and figured that IRIS while importing via %JSON.Adaptor wants JSON fields to match property names, meaning even should match the case. Like:

{ name: "John", 

surname: "Doe"}

will have issues while saving the dynamic object to a class Sample.Person with:

0 15
0 115

If both fields are numeric and the result of subtraction of field1-field2 is positive, only then put the result is a data field.

I am doing this within an Iris DTL.

I don't find any functions like IsNumeric(). Once I get that, I can test if field1>0 and field2>0, do the subtraction, and test if diff>0.

I just need a function to determine if they are numeric, rather than some cumbersome way like a regex where the only characters are 0-9.

I see functions in documentation but don't see them used at tests, only in WRITE statements.

Thanks,

Hello,

First of all: thanks for your help, and thank you for your time.

Thanks for your time.

We have the following situation:

We are in a BPL, and we have defined 4 <call> asynchronous as follows:

First one name: "Enviar a Proceso NEGRIN"

The second one, named as: "Enviar a Proceso HUNSC"

Is anyone using DICOM Interoperability in IRIS for Health configured in Mirror?

I'm asking because I'm not sure how to handle where the DICOM messages are stored.

For some reason DICOM use the filesystem to store raw messages, the directory used can be configured in the StorageLocation production settings, obviously this is a big issue if/when a mirror failover occur.

Unfortunately in IRIS it's not possible to change the DICOM storage from file stream to global stream.

Has anyone came across this issue?

Namespace vs database

I'm confused about the differences between a namespace and a database.

I understand that a database is a single IRIS.DATA file in a directory in the os hosting IRIS.

What is the difference between a namespace and a database?

Can I write data into a database without specifying a namespace?
If so how do I write to a particlar DB in objectscript?

Does a database have to be in a namespace?
Can a database be in more than one namespace?

Can a namespace have only one 'routine' database and only one 'data' database?

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?

Hello everyone! This is my first post into the developer community and one that I hope is fairly simple to answer. In our environment we currently have 3 different Test environments for testing before migrating code to our Prod environment. Currently we are working on establishing a source control method using Git in house which has been a bit of a struggle. We have also had developers that had used different test and migration methods in the past which has caused some issues with keeping the different test environment in sync.

I am receiving the garbled text due to incorrect encoding or decoding. I tried to use the $zconvert function to convert it into the normal text but failed to do that. Can anybody suggest what I have to use to convert that into normal text?

Example: Garbled text that I am getting is "canââ¬â¢t , theyââ¬â¢re".

I am receiving a FHIR response bundle back with a resource of patient. Using fromDao, I attempted to take the stream and put it into FHIRModel.R4.Patient but it is not mapping correctly. When I attempt to take FHIRModel.R4.Patient and write it out using toString(), all I am seeing is the resource

{"resourceType":"Patient"}

so the response is not mapping correctly to FHIRModel.R4.Patient. How have others handled this? Do I need to translate it to an SDA since it does fit the model format?

Hi,

My HL7 interface in production is outputting messages to a HL7 File Operation and a EnsLib.HL7.Operation.HTTPOperation. There is no errors in the File Operation, but the HL7 HTTPOperation is giving ERROR #5911: Character Set 'iso-8859-4' not installed, unable to perform character set translation. Both the HL7 File Operation and HL7 HTTP Operation are using latin1 for Default Char Encoding.

What is ERROR #5911 about? Is something missing in the IRIS installation?

How to create a signed JWT

I need to create a JWT to connect to EPIC FHIRserver sandbox.

https://fhir.epic.com/Documentation?docId=oauth2&section=BackendOAuth2Guide

You will generate a one-time use JSON Web Token (JWT) to authenticate your app to the authorization server and obtain an access token that can be used to authenticate your app's web service calls. There are several libraries for creating JWTs. See jwt.io for some examples.

I am trying to get the value of a Submit button on a CSP object page.

<input type="Submit" value="Assign" name="action" id="action">

I tried getting it thru $GET(%Request.Data("action")), but it throws an Undefined error. Isnt $GET supposed to handle it if its undefined anyway?

How do I get the "value" of the button pushed when the form is set to POST?

Hello, Does the NodeJs package work when running a node js file on windows (nodejs for windows)? I've added the package by running npm install <package location folder>

I have the following index.js file, but when running from node (windows) I get the following error. Does the NodeJs package build the output files when the package is added or does it just assume linux as the underlying os?

Error: Cannot find module './bin/winx64/irisnative.node'
