#UNCOMPLEXICATION OF CLINICAL INFOSTRUCTURE
AKA ‘a clinical modelling odyssey’

Healthcare's Big Problem With Little Data Gartner’s hype cycle: “Big Data” heading toward the
“Peak of Inflated Expectations”
“In the meantime, however, ”little data” in healthcare continues to give us all peptic ulcers”
“Clinical data at the unit level is chaotic and dysfunctional because it’s not easily transferable or usable outside of the system that first created it. In a world of competing financial interests and an increasingly mobile population – every patient encounter represents an opportunity for technology vendors to lock-in providers.”
“Historically, the crutch that many software vendors have relied on is the format of the data itself.”

The odyssey? 2004 – the ‘sneak preview’

The odyssey? 2004 – the ‘sneak preview’ 2007 – initial modelling for NHS
210 archetypes/49 templates 2 people/3 weeks – simple, pragmatic,
no review, no metadata Antenatal, Emergency Demonstrated capacity for:
Rapid development Archetype re-use
Need for CLUSTER archetypes identified

The odyssey? 2004 – the ‘sneak preview’ 2007 – initial modelling for NHS 2007 – ongoing NHS internal
modelling 691 archetypes; 60 templates Observations:
Lack of openEHR skills Technical modellers; lack of domain
experts Lack of common methodology;
coordination Not a specific NHS issue, but reflects the
human experience >> Identified need for Collaborative/Governance tool
![Page 7: #Uncomplexication of clinical infostructure - a clinical modelling odyssey](https://reader035.vdocument.in/reader035/viewer/2022070313/554b7248b4c90551118b5434/html5/thumbnails/7.jpg)
Initial Team Modelling - analysis Naming inconsistency Wrong class Modelling design
Lack of training Technical modeler Inconsistent patterns
Content scope, context and intent unclear Granularity:
Make into a template, OR Need to divide into multiple smaller archetypes
Minimal content change resulting in specialisation, but effectively just renaming.
Multiple versions of same concept Need to model generic concept comprehensively first, then
specialise Need to re-use existing archetypes Zero content change but created as new version

The odyssey? 2004 – the ‘sneak preview’ 2007 – initial modelling for NHS 2007 – ongoing NHS internal
modelling 2008 – CKM development
commences… Late 2008: Initial openEHR CKM
deployment – 250 archetypes, largely from the initial
NHS modelling work

Modelling momentum…
Fragmented, piece-meal, spurts or activity
Zero-resources ?Largely driven by Ocean

Happily, this is changing… Industry Group -> $$ for archetype
devt/pub More CKM instances with collaborative
mindset Norway, Slovenia, ?Brasil
Platform -> applications -> demand for archetypes

Lessons: CKM personpower
Single, standalone instance [vs shared instance] 2-3 Clinical Knowledge Administrators (CKA)
Oversight & responsibility for all of the clinical knowledge artefacts
Core team of skilled ‘archetype wranglers’ (4-8) Cohesive pool of archetypes Common mechanism for engagement with terminology Multidisciplinary team – informaticians, domain experts,
engineers, terminologists
Editorial leadership Content, Terminology, Translation
Distributed Template Authors ‘Light’ training, local needs
Broad online community of reviewers
