User Experience Stack Exchange is a question and answer site for user experience researchers and experts. It's 100% free, no registration required.

This is the workflow I am addressing and I'm looking for some feedback on the approach.

A user can perform the following functions:

  • Add Allergy (takes user to a form to fill out the details and adds it to the list of allergies upon hitting save)
  • Mark the patient's record with No Known Allergies
  • Mark the patient's record as Unknown (potentially the user has not visited with the patient yet but wants to document as Unknown as a reminder that they need to ask the patient about allergies)

Note: While the No Known vs. Unknown may be confusing, these options are clinically relevant so they can't be changed.

I'm proposing that the patient allergies screen shows these 3 options for the first view of this screen, when there haven't been any allergies added yet.

It would display these three options until the user either added the first allergy, or marked the patient's allergy as No Known or Unknown.

Once an allergy has been added, I'm proposing that the other two options No Known and Unknown be tucked under the top of the screen. This is similar to the pull down to refresh flavor.

Whenever the user returns to a screen that has allergies on the list, I'm proposing that these buttons display for a short period of time and then animate up with only a portion revealed as a reminder to the user that these will display. The user can pull down to access those buttons, but it will be rare that they would do that.

It's possible that the user would have an active list of allergies and then would need to be able to mark all items as Unknown or No Known. This serves as an undo mechanism in case they entered allergies for the wrong patient, etc. So these options still need to be available. However, this would be a rare scenario.

My question is around the approach of hiding the less used buttons and whether that's a good idea. I understand the design principle of Visibility, but in essence I am providing visibility to these buttons at all times when you enter the screen.

Quick Display of buttons if there are allergies

Initial View with no Allergies on List

Hidden view with swipe down to reveal

I don't think showing the buttons for a short time and then moving them is a good idea. You might put these (unlikely) options in the menu (always available in the menu) but have the buttons completely gone once an allergy is specified.

But it seems to me logically inconsistent to allow an allergy to be specified and be able to specify "No Known Allergies" or "Unknown". Wouldn't it be better if you had to explicitly delete the allergies (and perhaps requiring an explanation as why you're deleting them) before you can set the state to "No Known" or "Unknown"? If you take this path, once all the allergies were deleted the "No Known" and "Unknown" buttons would reappear.

+1. Unknown means nobody has asked the patient about allergies yet, None Known means no substance has given them an allergic reaction yet. Unknown is the entry state of the question. None known is a valid response that becomes invalid as soon as a new allergy is added, and defaults if a lone allergy is deleted. –  LindaBrammer Sep 8 '13 at 13:42
    
The buttons need to be available even if there are allergies on the list. Nothing gets "deleted". Selecting Unknown or No Known after allergies have been added deactivates the allergies on a list, but those still display. Since the audience is physicians and the device is mobile, the extra step of making them enter an explanation for deactivating these should probably be avoided to speed up the process, as clinically it's not required. Deactivating one at a time to disclose other buttons would be a slow process for patients with many allergies. Possibly "Deactivate All" could work. –  Dmacatude Sep 9 '13 at 18:17
    
@Dmacatude I see. Still I would remove the "No Known" and "Unknown" buttons once one allergy is added, but always have those actions available through the menu. (I once worked on medical software, kind of a strange world with all their rules and terminology ;)) –  obelia Sep 9 '13 at 21:22

You could move any actions that are performed frequently/infrequently up into the action bar, for example adding a + button next to the overflow when you are on the allergies tab. Anything you don't use often can be shifted to the overflow. I would leave the No Known button where it is, but move the Unknown to the action bar too to allow for quick sorting through records (one click in the action bar vs looking for the button). Once a patient has been marked as not having any known allergies this is unlikely to change frequently so you can leave this button where it is. As this is an Android app for 4.0 (judging by the interface) and above the user will be expecting functions on the action bar so it's not going to be too confusing for them.
