Oil & water: research & standards

The world of clinical modelling is exciting, relatively new and most definitely evolving. I have been modelling archetypes for over 8 years, yet each archetype presents a new challenge and often the need to apply my previous experience and clinical knowledge in order to tease out the best way to represent the clinical data. I am still learning from each archetype. And we are still definitely in the very early phases of understanding the requirements for appropriate governance and quality assurance. If I had been able to discern and document the ‘recipe’, then I would be the author of a best-selling ‘archetype cookbook’ by now. Unfortunately it is just not that easy. This is not a mature area of knowledge.

I think clinical knowledge modellers are predominantly still researchers.

In around 2009 a new work item around Detailed Clinical Models was proposed within ISO. I was nominated as an expert. I tried to contribute. Originally it was targeting publication as an International Standard but this was reduced to an International Specification in mid-development, following ballot feedback from national member bodies. This work has had a somewhat tortuous gestation, but only last week the DCM specification has finally been approved for publication – likely to be available in early 2014. Unfortunately I don’t think that it represents a common, much less consensus, view that represents the broad clinical modelling environment. I am neither pleased nor proud of the result.

From my point of view, development of an International Specification (much less the original International Standard) has been a very large step too far, way too fast. It will not be reviewed or revised for a number of years and so, on publication next year, the content will be locked down for a relatively long period of time, whilst the knowledge domain continues to grown and evolve.

Don’t misunderstand me – I’m not knocking the standards development process. Where there are well established processes and a chance of consensus amongst parties being achieved we have a great starting point for a standard, and the potential for ongoing engagement and refinement into the future. But…

A standards organisation is NOT the place to conduct research. It is like oil and water – they should be clearly separated. A standards development organisation is a place to consolidate and formalise well established knowledge and/or processes.

Personally, I think it would have been much more valuable first step to investigate and publish a simple ISO Technical Report on the current clinical modelling environment. Who is modelling? What is their approach? What can we learn from each approach that can be shared with others?

Way back in 2011 I started to pull together a list of those we knew to be working in this area, then shared it via Google Docs. I see that others have continued to contribute to this public document. I’m not proposing it as a comparable output, but I would love to see this further developed so the clinical modelling community might enhance and facilitate collaboration and discussion, publish research findings, and propose (and test) approaches for best practice.

The time for formal specifications and standards in the clinical knowledge domain will come.  But that time will be when the modelling community have established a mature domain, and have enough experience to determine what ‘best practice’ means in our clinical knowledge environment.

Watch out for the publication of prEN/ISO/DTS 13972-2, Health informatics – Detailed clinical models, characteristics and processes. It will be interesting to observe how it is taken up and used by the modelling community. Perhaps I will be proven wrong.

With thanks to Thomas Beale (@wolands_cat) for the original insight into why I found the 13972 process so frustrating – that we are indeed still conducting research!
