2. Healthcare realities …
Large and segmented
populations
Safety critical but distractible
environment
Generally poor IT infrastructure
Highly politicised
Culturally nuanced
Increasingly mobile ageing
population
Information governance issues
3. Healthcare is powered by information
To facilitate immediate care
To facilitate review of care
quality
To inform healthcare
management
To inform research
4. Why is health information so hard?
Very different kinds of information
Compressed, summarised
information
Reporting
Making sense of complex care
Large number of complex datatypes
not just string, numeric, url, date
6. Documentation of care
Immediate care context
Diagnosis (name, dates, grade)
Lab test (name, result)
Medico-legal context
Who, when, why, what, how
7. Compression and summarisation
Registry and research
coded diagnosis versus Y/N
‘Curated’ problem lists
Remove ‘inactive’ or trivial problems
Add new problems ? all problems
From whose perspective?
8. Medication ‘dose syntax’
How can we capture a prescription like
“Co-codamol 8mg/500mg/5ml oral suspension 5-10mls
4-6hourly for 7 days for pain, maximum 40mls daily”
How can we cope with dose vs product prescribing

14. Health information is nasty
Complexity is a challenge for
any e-Health developer
building APIs, messages
building apps
Need good requirements from
clinicians
How do we know they are widely
applicable?
How do we make sure that we
capture and share that clinical
knowledge?
