In Texas, you have to sign off on 10% of their charts. We have about 3 midlevel shifts at our ED; they come ask us if they have a big issue. They mainly see (ESI) 4s and 5s, occasionally will cherry pick some 3s if the is not enough of the others around.
Most of us have one mid level assigned to us and we sign the 10% of their charts that they send our way. Our charting program allows us to type stuff that DOES NOT become part of the medical record so we can say if we would have done something different, etc. We also get a small monthly stipend for them being under us.
We do not have to see that patient; its more of a 'chart review' that is often done weeks and sometimes months after the fact depending on how well you stay caught up.
