When a person enters the ER they are usually quickly triaged by a triage nurse or EMT and then asked to be seated. Each hospital has its own way of assigning the patients a priority, either by color or number.  This level the patient is assigned determines when they will be called back to be seen. From what we have seen is that the patient is NOT aware of the level/color they have been assigned.

Do you know of any examples where emergency departments make their patients aware of their priority (triage) level?
Could this understanding aid in the overall understanding of how the ER works, why people are waiting, why others who have arrived later are being seen prior?
