FHIR versus the EHR | Woland's cat
24-05-2019
One of the many things the FHIR silver bullet hype claims FHIR will solve is the EHR, along with Clinical Decision Support (CDS), Care Pathways, and who knows, paving driveways and launching spacecraft. I have made various arguments against silver …
A FHIR Experience – the formalism | Woland's cat
08-05-2019
This post continues the review presented in the previous post, where I looked at the Administrative resources of FHIR. Here I take a look at the formalism used in FHIR, i.e. how the resources (and profiles) are formally expressed. FHIR …
A FHIR experience: models or just definitions? | Woland's cat
06-05-2019
This is a second instalment of a technical review of the HL7 FHIR resources. As described in the previous post, this review is the result of an element-by-element transcription of the FHIR DSTU4 resources to the openEHR BMM (Basic-meta Model) …
A FHIR experience: consistently inconsistent | Woland's cat
05-05-2019
In recent work I am involved in, the HL7 FHIR DSTU4 resources were converted to the openEHR formalism known as Basic Meta-Model (BMM), which is published as an open specification. BMM is an object-oriented formalism, conceptually similar to UML (minus …
openEHR Task Planning – a visual model of clinical workflow | Woland's cat
17-04-2019
We have been making steady progress on the openEHR Task Planning specification and visual modelling language (TP-VML) for clinical workflow. One of the differentiators of Task Planning, is that, like YAWL, it is designed as a formalism for developing fully …
Why the NHS needs its own health-tech university | Woland's cat
06-04-2019
The NHS has around one million employees and serves most people in England and Wales. We could easily imagine a slightly larger organisation serving the whole UK, although for historical reasons Scotland and Northern Ireland are separate. Another large public …
Representing FHIR clinical content in openEHR | Blog - Atomica Informatics
19-03-2019
Over the past few days I’ve attempted the task of representing the FHIR Skin and Wound Assessment profiles using openEHR archetypes.
The long slow death of UML | Woland's cat
07-03-2019
The Unified Modelling Language aka UML has been around for 22 years, as you can see from the OMG UML page. We use it extensively to publish the openEHR specifications, in a similar way to many other organisations. Developers often …
A common data language is essential for digital health disruption | Blog - Atomica Informatics
02-01-2019
The lack of a common health data language has been ‘the elephant in the room’ for a very long time. Unfortunately, very few people acknowledge the need for a clinical lingua franca as a critical foundation for eHealth. The mainstream view seems to be that messages are/will be enough and that creating a standard language for health information is either too hard or too complicated. Is it really that hard? Or is that just the view of those with vested interest in perpetuating the message paradigm?
openEHR for policymakers | Musings of a confused technology addict.
01-01-2019
As of end of 2018, I’ve been working on openEHR for almost 15 years, beginning with my exposure to openEHR archetypes during a European Union research project, around 2003 or so. During these fifteen years, I tried to explain my (sometimes incorrect at the time) understanding of openEHR to many people who occupied various positions: …
