we just enter what ever we can
uusally john doe or the room/ bed number.
trauma patients are put in by registration before arrival (if we are that lucky

)as a sequentially number : jane / john doe trauma 182.
i guess the pharmacy fixes any problems later, i have never heard it even mentioned before.
the real problem we had, was with our new blood sugar machines. they originally only had them set up to take the pt id # to start up. which was a problem when some one in triage was went out secondary to low b.s. before they were registered.
they soon corrected that issue.
