User 3:
User 3, another female with little background experience in medicine, started with the nurse role. She immediately found the "Give Medication" button after tapping on the patient's name. She tapped the "Done" button next to the relevant row in the table, and vocalized her appreciation for the immediate feedback present in the page (our "computer" removed the row for the medication as soon as "Done" was tapped). As a doctor, the user noted the parallels she saw to the nurse's Overview screen, and found Mohammad's patient row without a problem. The user first removed the previous medications and knew (with the iterated form) what to put in the "Frequency" (drop-down), "Start", and "End" (date/time pickers) fields. The user chose to confirm the prescription within the dialog box rather than on the Overview screen. She notes that she would "check back later" and questions "what are alerts?" before tapping the Alerts tab. She was confused by confirming medication and by the opening of the "Give Medication" modal page when tapping on "Alerts" as a doctor (she correctly thought that the page was meant for nurses).

TODOUser 5:
TODO User 4 was a male, again with no medical training. He was able to accomplish all of the given tasks, but had difficulty with determining whether the patient was allergic to aspirin while on the "prescribe medication" screen, indicating that we need to ensure that information is prominently visible at all times. He also suggested that we make the modal information of the current user's scope of responsibility (doctor or nurse) more clear. He had some trouble finding the correct affordance to click to bring up the "Give Medication" screen.
User 5:
User 5 was a female with emergency medical training. She accomplished both user roles' tasks quickly and easily, but had two concerns that hindered her progress. First, as with many of our users, she found the "frequency" input unclear, but when it was replaced with a dropdown menu she found it much more understandable. Second, she felt that she wanted to ensure that there was some indication of the patient's immediate medication history in the sidebar so that it could be accessed from anywhere, especially in case she needed to find out if the patient had received any medication prior to ICU admission.

Analysis
Overall, we were pleased with our users' ability to navigate the interface. All the users accomplished all of the provided tasks correctly, and there were no errors in the prescribed or administered medications. The primary problems that our users faced were in locating context-dependent information such as patient allergies and in locating the correct buttons to activate the "Prescribe" and "Administer" interface elements.
