Clinicians on FHIR

Last week we held our first New Zealand ‘Clinicians on FHIR‘ seminar at the HINZ conference in Rotorua. This was really important for me, as it was the first ‘public outing’ of a seminar format that I’d like to see could be repeated wherever Clinicians are getting their first taste of FHIR, and showing how they can participate more fully in FHIR based Interoperability projects.

We had around 30 attendees and excellent participation – especially as the event was a combination of presentations and practical exercises. Thanks to John Fountain for presenting the clinical perspective. Talking to participants after the event was also very positive, with some good suggestions for improvement of the seminar.

Using a FHIR Observation

These are some notes written by Lloyd, Grahame & Eric about using Observation in practice. I’ve copied this directly, here so I always know where to find it. You should refer to the source for the most recent version.

FHIR Versions and Conformance URLs

As you probably know, there are a number of ‘conformance’ resources in FHIR that have a unique ‘canonical’ Url that identifies them globally. Other resources that need to refer to them can do so by addressing them by that URL – for example when a profile (Core or Derived) binds a coded element to a ValueSet, it does so via that URL – as does a Profile referencing an Extension Definition (both Profile and Extension Definition are StructureDefinition resources).

Looking at the definition of the Url in the spec:

For StructureDefinition:

An absolute URI that is used to identify this structure definition when it is referenced in a specification, model, design or an instance. This SHALL be a URL, SHOULD be globally unique, and SHOULD be an address at which this structure definition is (or will be) published. The URL SHOULD include the major version of the structure definition.

For ValueSet

An absolute URI that is used to identify this value set when it is referenced in a specification, model, design or an instance. This SHALL be a URL, SHOULD be globally unique, and SHOULD be an address at which this value set is (or will be) published. The URL SHOULD include the major version of the value set.

So how do you accomplish this across different versions of FHIR?

Creating documents in clinFHIR 

I did a demo of clinFHIR for the Clinicians on FHIR group that will be meeting at the Working Group Meeting next week, and completely forgot to talk about creating/viewing documents in clinFHIR using the scenario builder. This is functionality that has been around for a while, and allows you to create a FHIR document by adding a Composition resource to the scenario, and then linking up the other resource to it.

So I thought I’d do a post on it!

FHIR Core Extensions

A really short post to record how to download the core extensions in the spec (This came up in a FHIR Chat today). They can be found at:

This is particularly useful if you are setting up your own FHIR server and want to pre-load them with the code definitions in the spec. Just download from the link above, remove the id from the bundle, change the bundle type to ‘batch’ and POST to the root of the server.

Thanks Lloyd!

 

Creating Clinical and Analysis models

As you may know, one of the things that excites me about FHIR is the potential that it has to involve the clinician in the design of health IT systems (and I’m using ‘clinician’ in the widest sense – doctor, nurse allied health etc – anyone who delivers care to a patient).

So far a lot of my thoughts have been theory rather than practice, so it is great to try these ideas out on a real project – the reporting of Adverse Drug Reactions (ADR) by a clinician to a central service – such as a National EHR!

Using the clinFHIR query tool

I’ve been in China recently (attending the CHIMA conference and presenting on FHIR in a number of events), and while there I had a bit of spare time, so decided to give the clinFHIR query tool a bit of attention (I also needed it for the workshop I gave).

The query tool has been there for quite a while, but it’s been rather basic and a bit klunky, so a facelift was overdue! Read more of this post
