Information fragmentation
‘Too many clicks’
- Disrupts cognitive flow
- Increases memory load
- Increases risk of
- mission
- Increases frustration

2nd wave EHRs – computerizing information
Where to start?
- Most persistent complaints:
– Poor integration into clinical work – Poor usability
Miller et al. (2015) J Med Info 84:1009

The most common approach…
But… Patient processes? Clinical processes?
Business process – Service delivery approach
Initiating the service Initiating the service Providing the service Triggers & criteria for admission

Patients
Have:
– Health problems or concerns that change over a life-time → ‘womb to tomb’ – Life aspirations, goals, beliefs, values, priorities
Most come to hospital because they are sick. Often physiologically unstable, unpredictable, complex

Patient pathways
Post-op chest surgery pathway:
Pathway milestones: M1= Pt awake; M2 = Pt extubated M3 = vasoactives off; M4 = Pt out of bed
Patients on pathway Patients off pathway
- (Patho-) physiologically
grounded
- Evidence-based
- Link cues to actions
– feedback loops
- Ongoing plan of care
Goal = Pt ready for ICU discharge 48hrs post-op

Clinical work...Cognitive work
Situation Awareness
Information acquisition & processing (i.e. situation assessment; diagnosis) What is it? What does it mean? Where is it going?
Intervention Awareness
Action planning, execution & monitoring (i.e. therapy) What should be done? What was done? Did it work?
Global Situation Awareness

Why UX is important in EHR design
Human Centered Design:
- Focuses on understanding clinical work from
patient-clinician perspective
- Supports development of new approaches to
information design
- Consolidates inter-disciplinarity
