Here we discuss design decisions we made which were motivated by the three evaluations we did
Paper Prototyping
*Issue 1: * Users couldn't see patient allergy information when prescribing new medication
Design Fix: Make patient information sidebar visible at all times, providing consistency and context
*Issue 2: * Users were confused by "Add Medication" button while performing the nurse task
Design Fix: Make the Overview screen role-dependent, and switch "Add Medication" to Administer Tab with simple indicators.
*Issue 3: * Users were unsure of the input format for "Frequency", "Start", and "End"
Design Fix: Provide richer controls to alleviate formatting issues: a drop-down for Frequency, and a date-time picker for Start and End
*Issue 4: * Users found the alert icons ambiguous.
Design Fix: Added text indicators along with the alert icons.
Issue 5: The prescribe medication was a pop-up menu which users found annoying as it blocked parts of the screen they wanted to observe - such as patient information.
Design Fix: We eliminated the pop-up and placed the prescribe portion within the main pane of the interface.
Heuristic Evaluation
There were several fantastic points of feedback we received during the Heuristic Evaluation session, here we highlight the ones we felt were most useful and the corresponding design fixes to our interface.
Issue 1: Users could not sort patients by those needing the next dosage.
Design Fix: We added this functionality into by allowing various sorting options in the UI.
Issue 2: Our color indicators and accompany test accompanying text were confusing users of the interface. The interface used to display a red indicator and say how many minutes ago the dose was due. users were confused about weather the "ago" referred to their own administration, or what was due.
Design Fix: We changed the wording of the interface from "ago" to "overdue" to address this concern.
Issue 3: There was no easy way to sort prescriptions.
Design Fix: Prescriptions are now displayed in alphabetical order.
Issue 4: No auto-complete when prescribing medications.
Design Fix: We implemented auto-complete fro the nonprescription.
