But come on, how often does that actually happen? Oh wait, it's the most common complaint in the ER and accounts for about 5% of all ER complaints.
That almost makes my head hurt to think about.
With the ePCR, maybe you could have the pt fill out their demographics, if their condition allows. You could try saying something like, "I hate to do this, but it is required that I ask you, are you genetically male or female?"
