#InterSystems IRIS for Health

12

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.

I have been struggling sometime with trying to take a FHIR Bundle Response, extract the "entry.resourceType", extract the MRN and Name from the Patient FHIR Response...

Going through learning.intersystems.com, it suggested that I try using fhirPathAPI to parse and search my response for certain values, however I am not sure my syntax is correct. Using the AI code, it suggested to set my tree = "Bundle.entry.resource.resourceType"

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?

Using a WSDL and the SOAP wizard I created a WebServiceClient, and Operation to send an encoded message to a Vendor. But the vendor is now sending back an HL7 in the SOAP response.

I tried updating the Operation to Extend EnsLib.HL7.Operation.ReplyStandard, but still use the EnsLib.SOAP.OutboundAdapter. When I did this it broke my Operation and would not compile with the following error...

I am looking for a way to capture Data Quality issues with the Source data that is populating HealthShare Provider Directory. 1 way is to use Managed Alerts, but since it could be multiple Providers and different messages it seems silly to alert on every message that has the error. Instead, I was thinking of using the Workflow Engine so it could populate a Worklist for someone to review and work.

Looking over the Demo.Workflow Engine example, I am not comprehending on how to send a task to the Workflow manager to populate the worklist from a DTL.

When working with InterSystems Interoperability (Iris / Health Connect / Ensemble), configuration data is often spread across many production items: services, processes, operations, adapters, and their settings.

A common operational or security need is to answer questions like:

Here is what is currently used.

..CurrentDateTime("%Y%m%d%H%M%S")

The format is not the issue.

I need to make it our current time as it is five hours ahead.

How can I access the header property of either of these.

Or, if I can't do that, subtract five hours or the equivalent time in seconds.

example, if I receive 20201224161922, how can I make it 20201224111922?

Thanks,

Jonathan

Embeddedpy-bridge: A Toolkit for Embedded Python

Overview

Embedded Python is a game-changer for InterSystems IRIS, offering access to the vast Python ecosystem directly within the database. However, bridging the gap between ObjectScript and Python can sometimes feel like translating between two different worlds.

Sometimes it is more convenient, more efficient, and more secure, to limit FHIR Searches per pre-defined "Lists" of Resources.

Since v2025.1 we support several List-related features in our FHIR Server.

I will highlight these here, and provide some samples.

Hi,
Our production FHIR server is populated by several processes from several sources,
some of those sources send test data or wrong data (by mistake or as part of an integration test),
the data is consumed by our BI every 15 minutes.
when I mark a resource as test (using meta security) BI knows to update it on their system.
everything is fine up to here (except that there is test data in Prod)
my problem is that if someone send the same patient again it will recreate the patient without the security tag.
any thoughts?

InterSystems API Manager (IAM) is a core component of the InterSystems IRIS Data Platform, offering centralized API management with a strong emphasis on security. IAM simplifies the entire API lifecycle, from creation to retirement, and provides a developer portal for easy API discovery and integration. Access control features allow administrators to define precise permissions, and IAM seamlessly integrates with the IRIS Data Platform, enhancing data management and integration capabilities.

Features of IAM include:

You send an HTTP request and get back an HTTP error but with an HTML error page which you didn't expect... what's happening?... 🤔

Specifically for example, perhaps you tried to READ a FHIR Resource (e.g. /Patient/123) and you get back a 404 error page, even though with other Patient IDs, you get back the Resource payload, so "the page" definitely does exist... why should you be getting a 404 error page? 🙄

XDBC memory leaks

I have a business service that actively reads data from a remote Postgres database. OnProcessInput opens a XDBC (actually JDBC) connection, executes an SQL query, fetches several thousand rows, iterates the resultset, and closes the connection. On each iteration I also need to update each source row in the remote database using PreparedStatement.

In other words, in every OnProcessInput call I have a long running SELECT statement and several thousands small UPDATE statements.

The problems I'm facing are:

Looking at my database I see I have a very big ^rINDEXSQL global? Why is that? 😬

In the Management Portal SQL page, under "SQL Statements" I see a 'Clean stale' button - what does this do? 🤔

In the list of Statements some have a 'Location' value and some don't? How is that? 🤨

In this article, we will discuss all the debugging tools included in the Microsoft Visual Studio Code IDE.

What will be covered:

  • Breakpoints
  • Watch window
  • Call Stack

Let's start by learning about debugging requirements!

Prerequisites

There are two plugins (extensions) for debugging ObjectScript:

The first is part of the InterSystems ObjectScript Extension Pack. The second is Serenji, a standalone plugin that provides an editor, file manager, and debugging functionality. Both plugins can be installed from the plugin store. To activate key functionality, Serenji requires a license. For this article, we'll use the InterSystems ObjectScript Extension Pack to reduce the learning curve. After you've mastered the basics, you can consider purchasing a paid license for Serenji.

I am experimenting with OpenTelemetry and recently connected all IRIS instances to telemetry servers.
I'm not interested in emitting custom metrics since IRIS does it fine, regarding tracing - we can use %Trace classes to emit custom traces, but what about logging?

I see that IRIS is able to send system log messages to the OpenTelemetry servers:

An extension “extends” or enhances a FHIR resource or a data element in a custom way. The extension can be added to the root of a resource, such as “Patient.ethnicity” in US Core profile, and they can be added to individual elements such as HumanName, Address or Identifier.

Did you know that you can also add an extension to a primitive data type?

Primitives usually store a single item and are the most basic element in FHIR. For example: "Keren", false, 1234, 12/08/2024 etc.

For example, the patient resources might look like this:

I want to extract data from IRIS (Health Share Provider Directory) and write the data out to a file that I can use within an external system. Using EnsLib.SQL.Service.GenericService do I need to supply Credentials if I am querying IRIS locally? I have always used JDBC to connect externally when creating Services and Operations to read/write SQL data from external Databases, but never internally. Normally I would just use sql or code to pull the data within a Process or DTC. But in this case, I want the Service to drive the workflow, and query the data from Local Tables
