“Big data is like teenage sex:
everyone talks about it,
nobody really knows how to do it,
everyone thinks everyone else is doing it,
so everyone claims they are doing it...”
-- Dan Ariely @danariely (2013)
Substitute “Big data” with “AI”, “Blockchain”, “IoT”
of your choice.

• Life-or-Death
• Difficult to automate human decisions
– Nature of business
– Many & varied stakeholders
– Evolving standards of care
• Fragmented, poorly-coordinated systems
• Large, ever-growing & changing body of
knowledge
• High volume, low resources, little time
Why Healthcare Isn’t (Yet) “Smart”?

Clinical Decision Making

40. 4040
• The real place where most of the
values of health IT can be achieved
– Expert systems
• Based on artificial intelligence,
machine learning, rules, or
statistics
• Examples: differential
diagnoses, treatment options
(Shortliffe, 1976)
Clinical Decision Support Systems (CDS)

41. 4141
– Alerts & reminders
• Based on specified logical conditions
• Examples:
–Drug-allergy checks
–Drug-drug interaction checks
–Reminders for preventive services
–Clinical practice guideline integration

43. 4343
• Reference information or evidence-
based knowledge sources
–Drug reference databases
–Textbooks & journals
–Online literature (e.g. PubMed)
–Tools that help users easily access
references (e.g. Infobuttons)

▪ An informatics doctor thinks like a doctor but
designs IT applications to help other doctors
▪ Digital Health Transformation is, first and
foremost, about Health Care, not digital
technologies
▪ EHRs & CDS are examples of useful Health IT
▪ Human decisions are still necessary in
healthcare, so many health IT should work to
support human decisions as CDS
