2. Overview • Overall Problem and Solution • How we got to the final UI? • Lo Fi Prototype • Interactive Prototype • Final Prototype • User Study • Final study description and experimental design • Results • Conclusions

3. Overall Problem and Solution • How can we simplify the complexity of maintaining the quality of patient’s records, for medics? • We offer a friendly front-end interface for automating this administrative task. • The medics will be able to then improve accuracy and efficiency of maintaining records.

4. Lo Fi Prototype • Our Lo Fi prototype automated the task of reviewing the charts for completeness • We first designed an interface that would check the completeness of the charts in the database • When we tested the lo-fi prototype on a representative medic, she could not easily locate the completeness warnings, so we made the warnings clearer for the next implementation

5. Initial Prototype • We solved the previous problem by highlighting the warnings section. • Three major problems found through Heuristic Evaluation • System forces user to make update • The user could only exit from the Index Page • Unclear representation of status

6. Final Prototype – HE and Solutions • System forces user to make updates when exiting chart • Major design change of adding edit/view modes • User could only exit from the index page • Added exits, and exit checks at every screen • Unclear mapping of status numbers and their meanings • Conversion to a three value status representation

7. Final Prototype – HE and Solutions • System forces user to make updates when exiting chart • Major design change of adding edit/view modes • User could only exit from the index page • Added exits, and exit checks at every screen • Unclear mapping of status numbers and their meanings • Conversion to a three value status representation

8.

10. User Study Description • Participants • 3 medics from a non-profit clinic • Recruitment by asking for volunteers • Tasks • Completeness Check • Correctness Check • Printing out lab form • Method: Think Aloud Study

11. User Study Description (cont.) • Test Metrics • Productivity • Number of steps • Remarked feature was helpful or “cool” • Subjective ratings • Minimal Error Rates • “Wrong” clicks • Visibly searching for more than 10 seconds • Confused for more than 10 seconds • Asked for help • Visibly frustrated

12. Results - Productivity • Bottom-Line Data • 2 out of 3 participants rated QCopi high in productivity • Process Data • “It’s neat that it can print [lab forms]…That’s cool.” (Participant A) • “The check mark for completeness is kind of cool.” (Participant C)

13. Results – Minimal Errors • Bottom-Line Data • All participants had approx. 3 or fewer “wrong” clicks per task • Process Data • “I guess that’s a safety saving me from changing everything when I don’t want to…” (Participant C) • “Computers take a little while to get used to.” (Participant B)

14. Conclusion • Useful functions help increase productivity at the clinic • Automated checks help decrease errors in patient records • Subjective reactions: • thought was useful and “cool” • affinity for traditional paper and pen
