(unless someone is obviously intoxicated, can't verbalize mechanism of injury, can't walk and has no one to pick them up -
we draw to assess levels and determine when it would be safe to discharge the patient...we have held people for many hours).
There's your reason; that's what the doc will say. You know as well as I do that the ED staff constantly discusses the care of each and every patient behind the nurse's station, and every chart is picked up and perused. How many of you have won the bet on the alcohol level of an intoxicated pt? You don't have to access the computer to know that information at most facilities, and it's difficult to know what chart to post results on if you don't look at the lab result that just printed on the printer. Is the compliance Nazi going to fire the whole ED staff?
This situation is painful, I agree, but who did the drinking at a party populated with coworkers? It will be difficult to prove HIPAA violations when your charge nurse doesn't know what your alcohol level was, but talked with party friends about how slaughtered everybody got. You know how the talk is the day after a big party. Is there an ongoing problem with alcohol anyway? (Sorry to be devil's advocate; somebody hadda say it.

)
I would follow the previous posters' recommendations and get a lawyer, but it might be an uphill battle. It's going to be interesting to see just what your charge nurse has to say, and who is present in the room during the meeting. Good luck to you--hope your ankle gets better.
