Table 3 Re-design results based on scenario tests and prototype evaluation

Content: Remarks or events that indicate what information, and how much information should or should not be incorporated in the app. Remarks or events that indicate the usefulness or importance of certain content

“Protective measures, is it already in the app? Or in a protocol? (…) For your own protection” (Nurse 3). “We are talking about antibiotics, but would it be possible to use this for other medications as well?” ( Nurse 5).

41

Structure: Remarks or events that indicate how information should be structured or displayed

“For example, the Farmacotherapeutisch Kompas [website with pharmaceutical information] is very nice, but too complicated. Difficult to understand, at a glance. And this [the app] is just, this is very nice at a glance” (Nurse 10). “This is clear, everything I need is on this page” (Nurse 2). “Here for example, it is a lot of text. It would be better to make more subheadings or something” (Nurse 5).

13

Layout: Remarks about the layout; what the app looks like

“That it looks very good” (Nurse 10).

5

Functionality: Remarks or events that indicate what the app should or should not be able to do. Remarks or events that indicate how it functions/should function

“I would print pump protocols. I do that sometimes, I put them in the patient file (…) maybe it is me, if I would have a nice iPad, I would find that convenient as well” (Nurse 3).

13

Task perception: Remarks on, or events that describe current tasks or work methods, and remarks or events that indicate perception of what own task or physician tasks constitute

“We can have a look at it, but we cannot do anything about it. In principle, the physician is responsible for lab results. Sometimes we alert the physician when we see it, but we do not pay attention to these things, with antibiotics” (Nurse 1). “It is no tour task, really, but I think, you all work with people for people, so (…) you should be able to do something about it (…) because we are the ones, normally, who administer it.” (Nurse 6).

22

Implementation: Remarks or events that indicate how the app relates to the current information infrastructure or how it would fit into current work processes

“I think this is something for the physician, whether it is a small-spectrum or broad-spectrum antibiotic (…) for us, preparation and how you should administer it is important” (Nurse 2). “We are doing a lot on the computer already, I think it would best to have everything in one place, that you are with the patient and [have the information at hand]. We are heading that way anyway” (Nurse 9).
