Clinical Decision Logic Fun | Woland's cat
22-10-2020
How close can we get to making a clinical decision logic language look like the published guidelines which it is used to encode? Below is an openEHR Decision Logic Module (DLM) example, in the current form of the openEHR Decision …
Towards a standard analysis of computable guidelines, clinical workflow, decision support and … the curly braces problem | Woland's cat
24-06-2020
Why don’t we have widespread clinical decision support (CDS), computable guidelines, clinical workflow (plans), and why don’t the pieces we do have talk to the health record? The first time I heard such challenges framed was around 2000, and even …
Adventures in FHIRland | Blog - Atomica Informatics
11-03-2020
In February I attended the HL7 International meeting in Sydney. Despite being openly aligned with openEHR AND a clinician, a classic double whammy, I was universally welcomed. It was a treat to catch up with some long term colleagues and renew acquaintances whom I hadn’t seen for some years.
FHIR Fixes – the choice construct part I | Woland's cat
09-03-2020
I have posted before on the FHIR ‘choice’ construct, particularly here, where I have explained the problems of the choice construct (essentially: it’s an ad hoc constraint construct that subverts the type system, and doesn’t belong in typed formalisms; none …

FHIR Fixes – the Observation.value problem | Woland's cat
12-09-2019
As described in some detail in this earlier post on the FHIR formalism, a number of FHIR Resources contain ‘choice’ attributes of the form attribute[x], such as the one shown above in Observation. These are mapped in the FHIR UML …
Fixes for FHIR – the Admin Resources | Woland's cat
11-09-2019
In this post I revisit the issues with the FHIR Resources described in the earlier post – A FHIR experience: models or just definitions? To summarise: FHIR has no semantic inheritance, only a generic structural inheritance of Resources from abstract …
Why using HIT standards fails to achieve interoperability | Woland's cat
06-09-2019
I started working in the Health IT area in 1994, on a major European Commission funded project. I attended years of standards meetings at HL7, CEN and occasionally OMG and ISO from 1999 to about 2012. And I’ve observed the …
