Channelling Bob Dylan? Not quite! But it is interesting to see some emerging HL7 and openEHR activity, at least in this little part of the world – Australia and New Zealand 🙂
Maybe this is a model for the rest of the world – at least food for thought!
For too many long years there appears to have been a palpable barrier between the HL7 and openEHR communities. Some individuals have managed to bridge it, but there has definitely been a reluctance to engage at organisational level. It stems from before my time; I suspect vocal personalities with strong, diverging opinions were at the root. To some, it is a little like a religious argument – where “only my way is the right way”!
Be that as it may – the barrier appears to be softening and became evident to me for the first time back in January last year as I attended the HL7 meeting in Sydney. A full day openEHR workshop was presented by a diverse group of Australian companies plus NEHTA experts; Bob Dolin in attendance, amongst others. Keith Boone tweeted his initial impression of the openEHR approach after I demonstrated our tooling and then blogged about it. My thoughts were captured in my Adventures of a clinician in HL7 post.
Fast forward to 2012…
You may have seen some announcements from New Zealand. Firstly, publication in April of the Health Information Exchange Architecture Building Blocks where they specified “2.3.2 The data definitions of the Content Model shall be formulated as openEHR archetypes” within the “10040.2 HIE Content Model, a framework for the creation of a common set of logical data definitions” document.
And secondly: HL7 New Zealand and the openEHR Foundation signed a Statement of Collaboration – also announced April 2012. Now there’s a headline that might have been a surprise to many – HL7 NZ & openEHR clearly intending to work closely together!
Only last Thursday Hugh Leslie & I participated in a seminar, “Bringing the Electronic Health Record to Life,” organised by HL7 NZ, Health Informatics New Zealand (HINZ) and the University of Auckland. Prof Ed Hammond, ‘the father of HL7’, keynoted the meeting: “EHR – The Killer App”. In the afternoon mini-tutorials, David Hay presented on FHIR, and Hugh, I and Koray Atalag presented a little about our openEHR work, including clinical knowledge governance and clinician engagement. Koray (a HL7 NZ member and openEHR localisation program coordinator) announced within the meeting that HL7 NZ is the likely organisation to auspice a NZ chapter of openEHR. Now that definitely has to start to change the openEHR/HL7 dynamic somewhat, even if HL7 NZ is a relatively small international affiliate 🙂. The HL7 NZ leadership, to their absolute credit, are certainly not being constrained by any traditional ‘turf wars’.
The following day, last Friday, Hugh and I presented a full day workshop on openEHR, again sponsored by HL7 NZ, HINZ and the University of Auckland. As I understand it, this was the first opportunity for the openEHR approach to be socialised with the broader healthIT community in NZ; about 25 in attendance including members of the HL7 NZ Board, vendors, and regional and HealthIT Board reps. The focus was on how openEHR could support the creation of a range of technical artefacts to meet NZ’s requirements for CDA messaging (and beyond), generated from a cohesive and governed pool of clinical content models.
Interestingly we had a surprise attendee for the workshop – Ed Hammond joined us for the whole day. I won’t presume to guess what Ed has taken away from the day, although he did offer up a comment to the group about the value of exploring use of archetype content directly within CDA.
Post workshop one of the attendees tweeted:
“At #HINZ #openEHR talks last 2 days. openEHR is a fantastic foundation for practical action. Left knowing steps I will take. How cools that!”
And of course, there is an HL7 AU meeting in Sydney early next week entitled “FHIR? CIMI? openEHR? What’s the Future of eHealth & mHealth Standards?” The agenda:
- Keynote: Ed Hammond (again) – “FHIR, CIMI and openEHR – What’s the Future for eHealth Standards?”. [It will be very interesting to hear his opinion after last week’s openEHR exposure.]
- Grahame Grieve: “FHIR – What is it? Why has it suddenly become so popular?”
- Hugh Leslie: “Recent developments in openEHR and CDA”, and
- I’ll be reporting on the CIMI project.
It would be an interesting day to be a fly on the wall! 2 HL7-ers and 2 openEHR-ers addressing an HL7 meeting – all exploring alternatives to the current approaches!
So, keep your eye on the space where HL7 intersects with openEHR – might be some interesting developments.
Within the openEHR community, and definitely within Ocean Informatics where I work, we are certainly finding that significant interest is being certainly generated from many sources about the process of using standardised and governed openEHR clinical content as a means to generate range of technical artefacts, including CDA. The New Zealand national interest and activity is evident, as outlined above. And in addition:
- In Australia, NEHTA has piloted the use of clinician-reviewed archetypes from the NEHTA Clinical Knowledge Manager as the start point for generating a number of the PCEHR technical specifications. This work is ongoing and being extended.
- CIMI, the initiative that grew out of HL7 but is now independent, is seeking to develop an internationally agreed approach to clinical modelling and generation of multiple technical outputs. It has already agreed to utilise openEHR ADL 1.5 as its modelling formalism and is using the openEHR Reference Model as the starting point for developing a CIMI Reference Model. We watch this progress with interest.
- And Brazil’s national program has recently reconfirmed its intention to commence using openEHR.
Whether the final solution is openEHR or CIMI or even something else, I think that the advent of standardised clinical models as the common starting point for generation of a range of technical outputs is upon us. Ignore it at your peril. And specifically, I would suggest that HL7 International should be considering very seriously how to embrace this new approach.
Sticking with the quasi-gospel theme, maybe it is now a bit more like Curtis Mayfield’s “People Get Ready“:
People get ready
There’s a train a-coming
You don’t need no baggage
Just a-get on board
Let’s leave our baggage behind, get on the ‘train’ together to collaborate and create something that transcends any health IT domain turf war! Don’t get left behind…
