User 1, a male with little background experience in medicine, started with the Doctor role. He quickly knew to tap the patient's name and "Add Medication". He stumbled on the format of the "Frequency" field, but otherwise handled the "Add Medication" dialog box well. He seemed to quickly understand that the "X" next to each row of medication removed that row. He scanned the "Add Medication" dialog box for patient allergy information, and explicitly mentioned that he couldn't find the information he was looking for before realizing he had to return to the previous screen to learn about the patient.

He brought up an interesting difficulty: he was unsure if the interface represented actions that would be performed automatically, or if they were actions that were his responsibility. He also had a little bit of difficulty understanding what tapping the medication pane should do.

That is, . We made the decision to do this after User 1 struggled to find patient allergy information while prescribing a medication, and we thought having the patient information always accessible in the sidebar to be a reasonable approach.
A minor iteration came after the second test user, when we decided to explicitly rename the "Add Medication" button to "Give Medication" for the nurse role. This change introduced the first difference between the doctor and nurse views of the Overview screen, but, after careful analysis, we believe that differing interfaces might be ideal.
The second round of iterations focused on the input format of the "Add Medication" form. Specifically,
