Actually, I don't do it that way. Part of the reason I stay late at night is I enjoy trying to come up with workarounds. I always look at fixes or ways of doing things in the EMR as how one would do it in a paper chart, given we have many more years of experience with that.
So, given that, if one writes a progress note and says 30 mg of Zantac and meant 60 mg, they would strike through the 30 mg, write 60 mg above it, write the word "error" and then initial it. They wouldn't write an addendum at the bottom of the note stating I meant to say 60 mg. Now, it isn't the perfect analogy but pretty close.
I think (given what we have with AC and most EMRs), the closest to an audit trail when correcting would be to open the chart again with the original version, make a change which is adjacent to the error and time and date stamp it digitally with Shortkeys.
I SHOULD POINT OUT that this isn't the answer to the original question that Barb asked. Just a thought on how to correct a wrong note.
