#InterSystems IRIS for Health

EHR (Electronic Health Record) systems are modeled in a proprietary format/structure and are not based on market models such as FHIR or HL7. Some of these systems can interoperate data in a proprietary format for FHIR and other market models, but others can not. InterSystems has two platforms that can interoperate proprietary formats for market ones: InterSystems HealthShare Connect and InterSystems IRIS for Health.

Hello All, 

I'm trying to sign some custom JWT with x.509 certs but running into a problem with the signed JWT containing some information I need in the JOSE header.

Is there a way to get the "X5C:[]" header included in the signed JTW? IS this as easy as setting something like the following

Set JOSE("x5c") = "public key"

Thanks

John

Hi all,

I am trying to start the production after creating the business components in code, but I don't seem to be able to do so

Hi Community,

Watch this video to learn how the upcoming Healthcare Action Engine will combine event detection, complex logic, and a notification framework to improve synchronous and asynchronous notifications:

It is clear how to get the request header value with a specific name:

Class My.RestController Extends %CSP.REST
{

ClassMethod processRequest() As %Status
{
    #dim request as %CSP.Request 
    set request = %request
    set h = ##class(%REST.Impl).%GetHeader("...")
    ...    
    return $$$OK
}

But I can't figure out how to enumerate ALL the request headers (and also get all values).

Let's say you have Python including variable-length arguments methods. How can you call it from ObjectScript? 

def test1(*args):
  return sum(args)
  
def test2(**kwargs):
  a1 = kwargs.get("a1",None)
  a2 = kwargs.get("a2",None)
  return a1+a2

You can call this "a.py" from ObjectScript as below.  For **kwargs argument, create Dynamic Object in ObjectScript and put it into methods with <variablename>... (3 dots) format. 

    set a=##class(%SYS.Python).Import("a")
    write a.test1(1,2,3)   ;; 6
    set req={}
    set req.a1=10
    set req.a2=20
    write a.

InterSystems has corrected a defect that can cause corruption of databases and journal files on AIX systems with IBM POWER8 or later POWER processors. This defect can be triggered only when database or journal encryption is in use.

Hello InterSystems HL7 Community,

InterSystems Certification is developing a certification exam for InterSystems HL7 interface specialists and, if you match the exam candidate description given below, we would like you to beta test the exam. The dates the exam will be available for beta testing are March 28 - April 30, 2023. Interested beta testers should sign up now by emailing certification@intersystems.com (see below for more details). 

Note: The InterSystems HL7 Interface Specialist certification exam is version 2.

A common need for our customers is to configure both HealthShare HealthConnect and IRIS in high availability mode.

It's common for other integration engines on the market to be advertised as having "high availability" configurations, but that's not really true. In general, these solutions work with external databases and therefore, if these are not configured in high availability, when a database crash occurs or the connection to it is lost, the entire integration tool it becomes unusable.

I am trying to finish build for moving to IRIS HealthShare Health Connect 2022.1 from HealthShare Health Connect 2018.1.3. I am currently using Delegated Authentication using an AD group to match up to the Role in IRIS. The Role has access to everything but the HS Resources because we don't really use the HS Resources for anything. We are mainly using IRIS for the Interoperability Engine. 

When I run System Administration --> Security --> Security Advisor, I am getting the following error.... "

I'm always on the lookout for tools that make the development and testing of my interfaces more efficient. A couple of years ago I came across HL7 Spy, from Inner Harbour Software. It quickly became my go-to tool for running message comparison reports for interface engine migrations, message statistics gathering, and troubleshooting message receipt and delivery. It also offered enhanced functionality for things like fetching messages via sftp that other tools don't provide.

I've recently been working with HL7 Spy's author, Jon Reis, to enable support for fetching messages directly from the Ensemble message store. Its SQL Loader feature now has native Caché/IRIS support, and I've contributed a small server-side class to support the extraction of messages using it.

InterSystems is pleased to announce the 2023.1 release of InterSystems IRIS Data Platform, InterSystems IRIS for Health, HealthShare Health Connect, and InterSystems IRIS Studio are now Generally Available (GA).

2023.1 is an Extended Maintenance (EM) release. Many updates and enhancements have been added in 2023.1.

There are also brand-new capabilities, such as production-ready support for Columnar Storage, ability to use Bulk FHIR, and support to MacOS 13 Ventura

Hi Developers,

Enjoy watching the new video on InterSystems Developers YouTube:

⏯ Health Connect Cloud @ Global Summit 2022

Overview

Cross-Skilling from IRIS objectScript to Python it becomes clear there are some fascinating differences in syntax.

One of these areas was how Python returns Tuples from a method with automatic unpacking.

Effectively this presents as a method that returns multiple values. What an awesome invention :)

out1, out2 = some_function(in1, in2)

ObjectScript has an alternative approach with ByRef and Output parameters.

Do ##class(some_class).SomeMethod(.inAndOut1, in2, .out2)

Where:

• inAndOut1 is ByRef
• out2 is Output

The leading dot (".") in front of the variable name passes ByRef and for Output.

Hi all,

I'm trying to use LOAD DATA to insert 11k (11,377) rows of data. LOAD BULK DATA is not available for the version of IRIS I am using.

After calling LOAD DATA it says only 5,500 rows has been inserted. The LOAD DATA docs says any error rows are skipped and a count of skipped rows can be found in %SQL_Diag.Result however there are no results here. There are no errors in the xDBC error log either.

Why have over half the rows been skipped?

Hello,

I have Iris4Health community version (using for some development) running in a docker container and trying to enable TLS/SSL/HTTPS in the container. I have created the SSL cert chain (root ca/web site cert) via open SSL have the http.conf and http-local.conf file loaded on a durable volume. I have  also loaded the root CA in the trusted root cert store on the device that is connecting.

After inspecting the logs it looks like apache has loaded the certs and is listening on the correct port, but I am unable to connect to the mgmt portal via SSL.

InterSystems FAQ rubric

In this article, we will introduce how to deal with the situation: "I accidentally deleted a global!"

Backup files and journals are used to recover specific globals that have been accidentally deleted. Restoration is performed by specifying conditions and restoring journal records using the ^ZJRNFILT utility In this way, you can apply a point-in-time backup of the database up to and including deleting a specific global for journal records that contain deletions.

InterSystems is pleased to announce that the extended maintenance release of InterSystems IRIS, InterSystems IRIS for Health, and HealthShare Health Connect 2022.1.3 is now available. This release provides a few selected features and bug fixes for the previous 2022.1.x releases.

You can find additional information about what has changed on these pages:

• InterSystems IRIS
• InterSystems IRIS for Health
• HealthShare Health Connect

Please share your feedback through the Developer Community so we can build a better product together.

In our previous article we saw how to capture DICOM type files located in a folder in our server and how we could send them to a PACS software (in our case the ORTHANC open source solution) for storage and consultation. Well, in this article we are going to deal with the opposite movement.

In our example, we are going to configure our IRIS for Health production to receive images sent from our PACS via TCP/IP. To do this, we must include a Business Service of the standard EnsLib.DICOM.Service.TCP class that will allow us to configure receptions.

The ID of the last updated record can be obtained using the SQL function LAST_IDENTITY().
* This function can be used with embedded SQL or ODBC but not with Dynamic SQL, SQL Shell, or the Management Portal's SQL interface.

Here's an example of usage with simple Embedded SQL:

InterSystems has corrected a defect that can result in Enterprise Cache Protocol (ECP) client instability under rare conditions.

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

Impacted versions are 2022.1.x, 2022.2, and 2022.3:

InterSystems HealthShare®

The issue can only occur on ECP client systems. When this issue is triggered, processes may experience a <SYSTEM> or <DATABASE> error.

Welcome community members to a new article! this time we are going to test the interoperability capabilities of IRIS for Health to work with DICOM files.

Let's go to configure a short workshop using Docker. You'll find at the end of the article the URL to access to GitHub if you want to make it run in your own computer.

Previously to any configuration we are going to explain what is DICOM:

• DICOM is the acronym of Digital Imaging and Communication in Medicine and it's a images and medic data transmission standard.

InterSystems announces its fifth developer preview, as part of the developer preview program for the 2023.1 release.

The issue can be triggered when SQL Runtime Plan Choice (RTPC) is enabled (the default) and the query contains a "truth value" WHERE ? = ?

I've been working for some days in the connectivity between NodeJS client applications and IRIS as server using web sockets.

You can get all the information in relation to the web socket connections using IRIS as a client or as a server from this URL: https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cl…

For this example we are going to configure an asynchronous server, that would be really usefull to create a subscription manager for our productions.

I have tried to parse the output of this call:

https://fhir.loinc.org/CodeSystem/$lookup?system=http://loinc.org&code=28890-2

and I don't know what's the right class to use. 

I need to extract:

* different components of the LOINC code

* Component

* FSN

* LCN

Is there a nice class that I can use to extract the different components?

In this article, I am trying to walk through my deploying step of IAM on my EC2(ubuntu).

Hi folks!

Playing with InterSystems FHIR server. 

You can easily install it in IRIS for Health using FHIR template:

zpm "install fhir-server"

NB! For now the IPM command mentioned above works for a namespace called FHIRSERVER only.

I have a FHIR server in a local docker container with endpoint:

localhost:52773/fhir/r4
