Plenary presentation to the International College of Emergency Medicine, 2022 06 22
Key messages
- We have a silo mentality for health data
- Interminable patching between systems is unsustainable
- We need a new approach
-- a 'little data' ecosystem
-- driven by clinicians
--peer reviewed by clinicians to ensure 'fit for purpose'
-- 2 level modelling -> tightly governed archetypes + clinically diverse templates
-- Create maximal data sets per concept as data building blocks; reuse and share
When we use computers in healthcare, we have to face the inherent challenges of documenting the gentle art of clinical medicine into binary 0’s & 1’s.
In some areas this is simple. In others, not so much.
As humans we’re good at filling in the gaps.
Think of the most infuriating questionnaire you’ve tried to fill out as a proxy for some of the issues around health data design. Only Yes/No answers when there are shades of grey or it’s not applicable
multiple sub questions but only a single answer
Ambiguities
We can see this. The almost universal experience is that we know we can do it better, despite it being designed by intelligent, well meaning people
Yet somehow we aren’t as critical with out data design. We assume the data is good. We assume the data has been designed by someone who knows what they are doing.
But who ever looks under the hood of a digital application or checks out the data base.
How do we know that the atomic data at the heart of our clinical systems, applications, projects etc is fit for use, much less leveraging this information for accurate applications of decisions support, personalised medicine or AI.
Doomed to interminable and unsustainable patching between applications or domains
What does it take to have systems & data that are different?
My challenge to you is to think of this Lego city as an analogy for our EHRs.
With the unseen infrastructure of city planning, electricity, gas, water, sewage etc representing all of the largely unseen parts of the EHR – the architecture, security etc.
And the creations built of Lego bricks according to published patterns represent the content of the EHR.
