I guess I was just trying to give a workaround that is actually fairly easy for those wanting to practice only and not put the patients in the actual database.
I don't see why one couldn't have a very cheap computer which is set aside for practice AND for the Little Mr. No Show documentation, which could also be documented in the real AC if you wanted by having a patient named Not Yet Established Patient. Sort of like preregistering.
The PROBLEM is that while these are all good ideas and maybe even possible with VB, etc. adding buttons is not always such an easy alternative. It isn't as simple as changing a train track to alter the direction of the train, although it may take as much force. I think the real issue is that most EMRs were designed the same idea AC has -- to document real patients in real databases. While there are probably many that do both, I haven't seen them.
Just my opinion. Could easily be wrong.
