Fast Healthcare Interoperability Resources (FHIR, pronounced "fire") is a draft standard describing data formats and elements (known as "resources") and an application programming interface (API) for exchanging electronic health records

Official site

Hi Developers,

We'd like to highlight some outstanding projects created during the European Healthcare Hackathon 2023 in Prague.

Participants were presented with nine real-world healthcare challenges by IKEM and AstraZeneca.
InterSystems introduced to the participants an opportunity to use the FHIR repository and perform FHIR availability into their solutions by providing FHIR cloud services on AWS.

Meet the winners of our challenge:

1st place Čarodějové (PathoSync)

"The PathoSync software is a solid base for complex pathologist platforms. With the use of custom mapping, any laboratory can project their data into FHIR7 standard, which soon will be mandatory worldwide. This makes the digitalization process smoother. The connection with InterSystems assures quality and implements many healthcare features. Furthermore, the GDPR norms are strictly followed using the FHIR server based in Europe, so the usage of software follows the European standards."

Sometimes we need to convert FHIR message to HL7 V2, e.g. to register a patient to the PACS system.
In this article, I will explain the steps to achieve the desired by using IRIS FHIR Server production.

Below are the steps we need to follow:

  1. Make sure FHIRServer production is started.
  2. Register Business Service with FHIRServer endpoint.
  3. Define Business Processes to convert FHIR message to SDA and then Convert SDA to HL7 v2.
  4. Post JSON resource to FHIRServer endpoint and get HL7 V2 response.

Let's review the steps in detail.

Step 1. Make sure FHIRServer production is started

Open the production page and make sure Production is started. In the next step, we need to make sure business service HS.FHIRServer.Interop.Service is registered with FHIRServer

Introduction

I recently participated in a fantastically organized hands-on by @Patrick Jamieson in which an Angular application was configured together with an IRIS FHIR server following the protocols defined by SMART On FHIR and I found it really interesting, so I decided to develop my own Angular application and thus take advantage of what I learned to publish it in the Community.

SMART On FHIR

Let's see what Google tells us about SMART On FHIR:

What changes are to be made while customizing a FHIR server package when adding a new field. As provided in the documentation, we have a sample JSON package of favorite color and it is added in the table, but when we are adding a new field 'Insurance', it does not imports the package and says package already exists. We have three files of JSON

1) Package.JSON

2) SearchParameter.JSON

3) StructureDefination.JSON

What should we have to change for adding new field.

FHIR Profile Validation Issues

Hello Community,

I've created my FHIR patient profile and POST into FHIR endpoint in Intersystems FHIR Server. 

http:localhost:52773/fhirr4/StructureDefinition

I use the profile url into my Patient resource without the meet the profile requirements.

http:localhost:52773/fhirr4/Paient

The resource is stored successfully in the FHIR Server instead of a FHIR exception.

Why the resource doesn't validate with the mentioned profile?

Hi,

I have a scenario where I recognize that I have a duplicate patient in FHIR , both have a different set of data attached to them (Specimens / Observations / Conditions) and I want to transfer all the data from patient X to patient Y, and maybe mark patient X as not relevant or delete it IDK yet.

since Patch currently supports only single patch,

"The Conditional Patch query identified more than one resource."

Background

In 2021, I participated as an InterSystems mentor in a hackathon, where a newcomer to FHIR asked me if there was a tool to transform generic JSON data containing basic patient information into FHIR format. I informed her that I didn't know anything like that, unfortunately.

But that idea stays in my mind...

Several months later, in 2022, I came up with an idea to experiment: to train a named entity recognition (NER) to identify FHIR elements into generic texts. The training involved synthetic FHIR data generated by Synthea and the spaCy Python library.

What is clinFHIR?

clinFHIR is a web application that has been developed pretty much over the same time as FHIR has.

Originally developed to help clinicians visualize FHIR (hence the ‘clin’ in the name) it has become more widely used by the FHIR community for learning FHIR and assisting with design. It is maintained by David Hay - one of the FHIR Management Group co-chairs with support from InterSystems, which is much appreciated!

There are 4 modules that may be of interest to participants in the upcoming Interoperability contest.

  • The Patient viewer for looking at an individual patients records
  • Server Query which makes RESTful API calls against a FHIR server displaying the result in different formats
  • Bundle Visualizer which will display the contents of a bundle
  • Graph Builder which allows you to build graphs of interconnected resources.

I’ve created a longer post on google docs that goes into a little more details of these modules, with links to other resources such as my blog and the R4 Specification and R5 FHIR specification. I’ll be enhancing that over time - feel free to comment.

A note with regard to FHIR versions. The latest version is R5 (release 5), though many in the community still use R4. In most cases, if you're not sure then use R4. If you're not sure which version a FHIR Server supports, examine its CapabilityStatement which you can get from the server endpoint [host]/metadata

I should also point out that clinFHIR doesn’t currently use SSL. It is on the roadmap, but there are a few issues to work through. The consequence of this is that if you enter ‘clinfhir.com' into the browser, it may not find it. You sometimes have to specify http://clinfhir.com/ .

If you need further assistance, I would alway recommend using the FHIR chat, and if your question / comment / suggestion is related to clinFHIR then there’s a specific stream there.

Overview

In our previous post, we discussed the motivation for developing a chatbot agent with access to FHIR resources. In this post, we will dive into the high-level design aspects of integrating a Streamlit-based chat interface with a Java SpringBoot backend, and enabling a LangChain agent with access to FHIR (Fast Healthcare Interoperability Resources) via APIs.

Mind map your FHIR patient data

According Wikipedia a mind map is a diagram used to visually organize information into a hierarchy, showing relationships among pieces of the whole. It is often created around a single concept, drawn as an image in the center of a blank page, to which associated representations of ideas such as images, words and parts of words are added. Major ideas are connected directly to the central concept, and other ideas branch out from those major ideas.

Hello everyone,

I am working with InterSystems IRIS and seeking guidance on how to perform specific tasks related to the FHIR SQL Builder using commands or code, rather than the graphical user interface (GUI). The specific tasks I am trying to accomplish are:

Hi Community,

I would like to know how I can query a list of patients that were revoked on HealthShare for the month of April and May.

Messages are sent using FHIR and a revoke is handled with active:false as seen below. A non-revocation will have active: true on the patient resource.

I wanted to check SQL tables but I am not sure which one to check if so. Please advise on how to go about getting this report.

Regards,

Get familiar with FHIR

🔥 Curious about the FHIR standard that everyone's talking about?

📚 Read on for a brief introduction, then try a brand-new learning path to get more in-depth knowledge!

The HL7® FHIR® standard has revolutionized the way healthcare developers take on the challenges of data interoperability. FHIR allows healthcare systems to exchange information seamlessly, and patient data can be consolidated in real time, regardless of where it's stored.

I created this application considering how to convert images such as prescription forms into FHIR messages

It recognizes the text in the image through OCR technology and extracts it, which is then transformed into fhir messages through AI (LLA language model).

Finally, sending the message to the fhir server of IntereSystems can verify whether the message meets the fhir requirements. If approved, it can be viewed on the select page.
