It's far more important to
know what person the
disease has than what
disease the person has.
Hippocrates
A computer would deserve to
be called intelligent if it could
deceive a human into
believing that it was human.
Alan Turing

Human errors
• Endogenous versus exogenous
• Situation assessment versus response planning
• Problem detection • Diagnosis • Planning and execution
• Level of analysis • Perceptual • Cognitive
• Communication • Organizational

Risks of human interpretation
• Routine, overseeing of details, lack of focus
• Tunnel vision
• Confirmation bias (wishful thinking, ‘Hineininterpretierung’)
• Emotion
• Human memory

Lessons from the Aviation industry
•Efficiency
•Legibility / readability
•Safety culture
•Crew Resource Management
•And lots more….

Information
• Should be presented “ ready to digest” = ready to decide
• Additional information should always be readily available “on demand”
• Routine is handled by the “autopilot” (= clinical pathways)

Focus on the most relevant items (data filtering)
Information-related disasters
•Too little: missing
•Too much: overwhelmed
Loss of
“situational awareness”

Data validity
• Source
• Validation steps?
• Who • How • When • …
• Gather data from the normal, intuitive workflow
• Caution with making entries mandatory and using defaults
![Page 20: Bridging the gap · Bridging the gap Tussen kunst en kunde Ronald Petru, kinderarts-intensivist CMIO Radboudumc, Nijmegen . ... Subjective ‘Art’, creativity Diagnosis, prognosis](https://reader034.fdocuments.in/reader034/viewer/2022050202/5f5608f86ee1600bcc1827a9/html5/thumbnails/20.jpg)
Data interpretation • Small amounts: charts
• Larger amounts: graphical display (curves, trends)
• Huge amounts
• Complex graphical presentation • Show relevant relationships • Use multiple dimensions, visual and others
• Trend analysis?
“Everything that can be counted
does not necessarily count;
everything that counts cannot
necessarily be counted.”

Predict and prevent (adverse) events rather than to act on them

Word of caution on using “Big Data”
• Distribution with 95% confidence interval
• A priori probability -> predictive value
• Medical diagnose ≠ direct marketing
![Page 31: Bridging the gap · Bridging the gap Tussen kunst en kunde Ronald Petru, kinderarts-intensivist CMIO Radboudumc, Nijmegen . ... Subjective ‘Art’, creativity Diagnosis, prognosis](https://reader034.fdocuments.in/reader034/viewer/2022050202/5f5608f86ee1600bcc1827a9/html5/thumbnails/31.jpg)
Correlation validity <-> “p-hacking”
• “Traditional scientific evidence”:
• Hypothesis: H0 versus H1
• P < 0,05 Chance of coincidence is 1:20
• What if we test multiple hypotheses at the same time…..
• (do NOT ‘torture the data until they obey….’)

Conclusion: (Big) Data ≠ Information
ronald.petru@ .nl
• Data can lead to information
• Big Data can lead to more information
• Information must be translated into data • In order to support the human provider (brain)
• (Big) Data can, do, and will help to improve care
• In the end: it’s the information that counts!
• As a part of patient centred care
• With the ‘Art of Medicine’ and compassion
• Be cautious with traditional ‘scientific evidence’
