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.

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
![Page 5: QCopi Q uality C ontrol o f p atient i nformation Final Presentation December 4, 2002](https://reader035.vdocuments.site/reader035/viewer/2022062422/568134e7550346895d9c1e4b/html5/thumbnails/5.jpg)
Initial Prototype We solved the previous problem by highlighting
the warnings section.
Three major problems found through Heuristic Evaluation
1. System forces user to make update2. The user could only exit from the Index Page 3. Unclear representation of status
![Page 6: QCopi Q uality C ontrol o f p atient i nformation Final Presentation December 4, 2002](https://reader035.vdocuments.site/reader035/viewer/2022062422/568134e7550346895d9c1e4b/html5/thumbnails/6.jpg)
1. System forces user to make updates when exiting charto Major design change of adding
edit/view modes
2. User could only exit from the index pageo Added exits, and exit checks at
every screen
3. Unclear mapping of status numbers and their meaningso Conversion to a three value
status representation
Final Prototype – HE and Solutions

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

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)

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.”
