So agree with the color and time thing. My O.R. crew made a snide comment about the time on the H&P for the allergy. It also says "entered by M.A. 8/2/10 at 3:17pm". They thought it was hilarious that my EMR printed out who entered the Allergy and at the exact time and date. Like I'm tracking my staff to know who and when things are entered. Now the O.R. staff thing I'm more of a control freak than they already thought.
It's fine to document the date entered and the person who entered it. It doesn't need to be red and it sure the hell doesn't need to be printed on the H&P. Hell, JCAHO doesn't even require that.
