• Motivation and result

• User-centered rapid-prototyping

• Implementation details

• Evaluation

• Limitations

• Conclusion


Medication information is complex

• 3 discussion groups

• “Why do I have to take so much medication?”

• “What are the adverse reactions for baby/wife?”

• “What are my adverse reactions?”

• “I need help with the choice between two bad alternatives”

• “GP asks me to bring all my medication to the practice”

• Health literacy

Motivation


Can information visualization techniques help?

Hard for general practitioner to explain

Patients bring all their medication to their GP

Medication information is complex and hard to understand

Biggest difference


Patients General practitioners

• Patients• like to see all possible adverse reactions

• have the feeling their GP hides information for them

• like that they have the same view as their GP

• General practitioners• worried about the Nocebo phenomenon

• want to remain in control

Final evaluation

• 25 participants• 16 males + 9 females, average age 32 ranging from 18 to 75

• Pre-questionnaire• demographics, basic health information

• Task-based scenario• concurrent think aloud protocol

• time-to-task

• number of errors

• Post-questionnaires• dialogue questions

• perceived usefulness questionnaire

• system usability scale

Limitations

• Animations not in real time• ± 1s per box

• Evaluation setting • not ’in the wild’

• No comparison• primarily to evaluate if visualization can increase

comprehension

• Privacy issues are not considered• used in private setting between GP and patient


Looking for collaborations!

• Redesign the visualization for private use• improve detection of medication boxes

• consider difficulties of private use

• evaluate if self-reflection is triggered


Conclusion

• Succesful proof-of-concept to increase

comprehension of medication information

• Our design shows useful feedback

• Better for personal use, as help of GP is not

needed
