@cconrad@ac: I see no point in going through the trouble of "deleting" when you can then "show deleted." Frankly that is just a waste of time.
Most other EMR I am familiar with only allow you to place an addendum stating an entry was made in error. This makes sense. Makes you pay attention when you save, in my opinion. As a surgeon I understand this concept well. I do not get to make the cut again because I did not like the first one I made! Measure twice, cut once...
Ps: Before you go there @cconrad@ac, this is completely different from adding pages to imported items, which are not part of the EMR.
