- Learnability
- When the user clicks done - there is immediate visual feedback telling the user when the dose was given and the dosage indicator in this case went from red to green
- Safety
- Accidentally clicked administrations may easily be undone.
Important Design Decisions
Here we discuss design decisions we made which were motivated by the three evaluations we did
...
General Feedback: When we performed this user test, we observed that our user struggled the most at the administration of the dose. Otherwise, the user completed the tasks quickly and efficiently. When asked what their general impression he was generally complimentary about the design and utility of the interface, but felt it needed some more work to maximize it's efficiency in an ICU setting. Here we will present the usability problems and solution we might implement to address the issues brought up in this usability interview.
Wiki Markup - \[Minor\] In the prescriptions menu, the user didn't like that bogus units could be entered.
Wiki Markup - [Minor\] In the prescriptions menu, the user suggestedthe user suggested moving the "now" button to the top and making it more prominent .
Wiki Markup - \[Minor\] In the main menu, If If you click the red indicator on the right of the patient, it should link you to the administration screen.
Wiki Markup - \[Cosmetic\] The overview information should be moved to the sidebar, and the prescriptions/ administration information should remain where they are.
What we would plan to address:
We agreed with several of the usability problems that User 1 pointed out. In the next cycle of our iterative design process we would likely incorporate all of his feedback into the next version of the interface.

General Feedback: We first gave a very brief explanation of the scope of the application to Dr. X, then let him use the application without interfering, simply writing down his remarks. Dr. X found the application is straightforward to use. Within a few minutes he had understood how it works, both from the physician and from the nurse standpoint. He gave us a few advice/remarks:
...
- \[Major\] In order to to assess patient order to to assess patient Mohammad, the user wants to see the previous observations on the patient. This issue is inherent to the fact that we have narrowed the scope of our application.
Wiki Markup - \[Feature request\] In the vital signals, it would be good to display the patient's temperature. As the temperature isn't taken regularly, it should go along with the time at which it has been taken.
Wiki Markup - \[Major\] The user found a bit surprising that the application maintains two different list of medications: other medications vs. prescriptions. In the ICU, most patients are able to medicate themselves so it would probably makes more sense to add the other medications within the prescriptions.add the other medications within the prescriptions.
- [Major] When adding a new prescription, the physician has to indicate in which units the dosage is expressed. This could lead to dangerous typo
Wiki Markup - \[Minor\] Related to the previous point, usually the dosage is indicated within the drug's name, e.g. "Aspirin-100" stands for aspirin 100 mg. Not only does this prevent typos, but it also allows the physician to prescribe drugs that are available in the hospital's drugstore. For instance prescribing Aspirin 150 mg would be difficult to administer if only Aspirin-100 and Aspirin-200 are available. Not only does this prevent typos, but it also allows the physician to prescribe drugs that are available in the hospital's drugstore.

What we would plan to address:
Dr. X pointed out some very interesting issues, which we would definitely take into account in the next release of the application.

General Feedback: General Feedback: We first gave a very brief explanation of the scope of the application to Dr. Y, then let him use the application without interfering, simply writing down his remarks. Like Dr. X, he didn't have any blocking issue when using the application. . He gave us a few advice/remarks:

- \[Minor\] In the right box, having the Patient History is much less interesting than the having the Patient History is much less interesting than the patient's immediate history.

- [Feature request] The dosage can sometimes be variable, either increasing or decreasing over the time, depending on the evolution of the patient. Even more intricate but also commonly used, it is sometimes up to the nurse to decide what dose to administer to the patient. For instance, if the physician has prescribed more fine for a patient, the physician might simply say to the nurse to apply the usual protocol when administering morphine, which gives the nurse flexibility on the dose, and also the patient is given a morphine pump that he can use to medicate himself according to how much pain he feels (obviously such a device is limited so that a patient cannot put his life into
