Implementing FHIR Profiles on IRIS

What is a FHIR Profile?

A FHIR profile is a collection of rules and constraints used to customize and refine a base Fast Healthcare Interoperability Resources (FHIR) resource. Profiling is a vital process that adapts the base FHIR resource standard to satisfy the unique requirements of a specific use case, geographic region, medical institution, or clinical workflow.

While the base FHIR specification provides generic, flexible definitions for resources (such as Patient, Observation, or Medication), profiles transform these generic resources into more precise ones. This ensures consistent and interoperable data exchange tailored for a particular community or implementation.

FHIR is designed to cover various healthcare scenarios globally. Profiles allow implementers to adapt this general platform without losing the benefits of standardization.

New to using Analytics and using Dashboards. We have this Report, SQL Query that lists out the Activity per Data Source in Health Share Provider Directory. Instead of running it as a report, because it takes a while to run, was wondering if there is a way to do this as a Dashboard instead.

How can I take the SQL from this report and create a Dashboard instead?

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:

InterSystems IRIS is built on an architecture that separates the logical organization of data (namespaces) from its physical storage location (databases). Understanding this separation and the distinction between Namespaces and Databases is crucial for effective data management, security, and especially, high-performance data sharing.

In this article, I will discuss these foundational components and provide a practical guide on leveraging global mappings to share native data structures (globals) across different logical environments.

Databases: Physical Reality

A database represents the physical reality of where the data is stored on the disk. First and foremost, it’s a file in a file system called IRIS.dat (e.g., <Install folder>\mgr\user\IRIS.DAT). The maximum size of this file is 32TB. It is the container for all the actual data and the code. Databases are managed by the IRIS kernel, which handles caching, journaling, and transaction logging at the physical file level.

When you install InterSystems IRIS DBMS, the following databases are installed automatically:

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.

HealthShare - FHIR gateway

I'm new to HealthShare. I've installed a demo using the HS.Util.Installer helper, now I'm playing with its FHIR Gateway (which is the HSFHIR namespace). When I try to create a new resource of type Patient using HTTP POST, HealthShare responses with

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.

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?

The Power of Indexing in Database Tables

When working with databases, most developers understand the concept of an index and why it's used: to speed up data retrieval. But the real impact of indexing often becomes clear only when you compare scenarios with and without it.

Do you Know what Happens Without an Index?
Imagine a table with three columns: Name, Age, and MobileNumber.

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
