HL7® FHIR® and SNOMED CT® Implementation Workshop

Return to eHealthNews.nz home page

This year’s HL7NZ mid-year event will focus on practical concerns with regard to the adoption of the critical HL7® FHIR® and SNOMED CT® standards in the NZ Health & Disability Sector.

The event is being held on Wednesday 19 June 2019 at the Novotel Auckland Airport and will consist of two separate streams, one of which is an HL7® FHIR® Connectathon lead by HL7NZ chair emeritus and co-chair FHIR management group David Hay.

Hay said that the Ministry of Health is working on exposing access to the NHI & HPI services through FHIR interfaces.

“This is a critical first step in establishing the digital healthcare ecosystem and it’s great that the Ministry is working with HL7 New Zealand on this work,” he said.

“So, as part of our mid-year event this year, HL7 New Zealand is planning to hold a Connectathon as one of the tracks, themed on what you will need to know to use these interfaces. The Connectathon is targeted at implementers (we’ll be looking at code at times), and will be a combination of presentations and practical exercises.

“The goal is that by the end of the day you’ll have enough information to start planning the development needed to access these services once they are available (and to participate in testing if you wish).”

The Connectathon will start with a presentation that reviews FHIR RESTful queries, and also the wire structure of the FHIR responses – resources, extensions and bundles – as well as the responsibilities of a FHIR client. It will look at the NHI/NHI resource structures in some detail, as well as touching on terminology interaction.

It will then move on to security, and spend some time on the widely used OAuth2/OpenID Connect (the standards that SMART is based on). This will be a general discussion (though technically detailed) as the details of how this will be deployed by the NHI project are still under development.

After that comes the practical part of the day – retrieving Patients from the NHI via FHIR (or, at least, an example server that exposes the planned interface) – with sample data conforming to the NHI specification which will be released shortly, as well as interaction with HPI services.

The Server will expose test data through both a secure and an insecure endpoint.  In addition to all that, there will also be FHIR experts present happy to talk about other questions.
