Clinicians rely heavily on previous “summary documents”
“[Anaesthetic report] is good because you know someone has trawled through the history and pulled this together” – ICU Registrar

Day 2 Understanding the problem Discuss range of ideas
Design Sprint
Day 1 Day 3 Consolidate ideas into a basic prototype Iterate Create a testable prototype for users
SLIDE 17
Day 1: Understand
SLIDE 18
▸ Present user research from contextual enquiry ▸ Decide and align on the understanding of the problem
Day 1: Understand
SLIDE 19

How might we make it faster and easier for clinicians to find information about a patient?
SLIDE 20
Day 2: Diverge
SLIDE 21
▸ No idea constraints ▸ Multiple ideas for solving problem ▸ Short sketching exercises ▸ Withhold judgement
Day 2: Diverge
SLIDE 22
“How might we" Questions
▸ “HMW enable clinicians to search/explore across a patient’s record?” ▸ “HMW show related clinical concepts present in a patient’s record?”
▸ “HMW highlight relevant segments of a clinical document?”
SLIDE 23
Day 3: Converge
SLIDE 24
24
SLIDE 25
▸ Review solution sketches and votes ▸ Which ideas are similar? ▸ Which are really different? ▸ As a group, combine ideas into one solution

“…this would mean not needing to flick through three or four discharge summaries… – Critical Care Outreach Nurse
SLIDE 36
▸ Copy paste paradigm ▸ Capturing/surfacing context ▸ Data quality ▸ Availability of clinicians
Challenges
SLIDE 37
▸ Continue iteration and clinical validation ▸ Develop a Proof of Concept with local data and clinical scenarios ▸ Measure success – compare time, accuracy and user satisfaction ▸ Develop product
Next Steps
SLIDE 38
▸ Design Sprints can be an effective tool for working with clinical end users ▸ SNOMED CT can support intuitive clinical interfaces ▸ Natural Language Processing can be limited by the original data
