If you ask the kids from Wake Forest, there is a slight ambiguity towards it. It is extremely fast (remember, you need to say "insert my standard ali raja complete this dictation template"), but you end up not writing anything down, so until it is typed out, nobody can see anything.
On the flip side, the WF people used to dictate, then went to a computer system. You don't remember the patients as well because you aren't going through the same mental pathways, according to them. It also takes longer to find the correct things and click them.
However, your hand doesn't get as tired from either of them as it does somewhere where you have t-sheets (Jax et al.)
