Test result display - User research & usability testing
Updating the display of test results
The first round of research
We collated all feedback sent in from patients and professionals in the past and reviewed it in detail. This gave us an initial idea of what the users wanted and we were able to draft some initial designs.
Removing all numbers from charts except the latest result
Showing the value only for the latest result in a detailed information pop-up style
Changing the detailed information pop-up so that the value comes first and then the date and range and additional info
Changing markers from filled to with an outline to make the result stand out
Only showing the range line when hovering over a result
Adding result values to notification panel
Highlighting latest result
Further wireframe testing
Three versions used for wireframe testing
Preference testing - Showing whether results are in or out of range
The first test we tested three variations with only minor differences. What we wanted to know is which layout helps certain information stand out more clearly, in this case this information was the out-of-range test result. In the test, we showed people all three variations next to each other in random order and then asked “which design helps you spot your out-of-range test result more clearly?”
Version 1 had the labels on the right side of the result.
Version 2 had the in-range and out-of-range label tokens below the test result value.
Version 3 was just simply written out and the label was not featured so prominently.
The outcome was that the overall majority (87%) favoured Version 1 (the one with the label token to the right as opposed to below the value (13%) or written out without a token (0%).
First-click testing are in or out of range
Outcomes from preference and click testing
Showing whether results are in or out of range
We will use the more prominent labels on the right side of the result
The final round of research and interviews
We used all the previous feedback and usability testing results to adapt the designs so that they would meet user needs based on the feedback and user testing done so far.
We then used these new designs to carry out further usability testing with renal patients that had sent us feedback on how to improve our display in the past.
We interviewed these users about their experience with other systems and their new experience with PKB, and then showed them our new designs and asked for their feedback.
The user's reaction to the new designs was positive and their insight helped us make some further important changes, including layout changes and how we indicate out-of-range results.
