This is what we do:
We have an assignment sheet for each shift - Days, PMs, and Nights. These are written in pencil and held onto by the charge nurse. It lists each nurse who will be working during that shift and what babies she is assigned. This is where we look to see what our assignments are. It also lists who is first, second, and third admit - plus who their babies are delegated to if they do get an admission (we give up our assignment when we get new admissions). It'll say who is holding the high risk delivery pager, who is supposed to check each crash cart that shift, etc. While the charge nurse hangs onto this pencil-written copy (so changes can be made) and files it away after the shift, there are copies made that float around for all to see, and these are recycled at the end of the day - the hospital shreds them first of course.
We do nurse-to-nurse bedside report, of course, at change of shift. This usually only lasts 10-20 minutes because we have very nice patient care summaries printed out from the computer system which has all the current orders for each baby plus an MAR. On weekdays, we do a full unit report at 7am, 3pm, and 11pm - weekends it's only at 7am and 7pm because most people do 12 hour shifts on the weekends. For this report, we meet at the beginning of our shift in the conference room and the charge nurse tells all the oncoming nurses what's going on in the unit. She'll have a page of "highlights" that doesn't talk about every baby - usually only about half of them. It's not a full report at all - just like, "Baby Jones is going home later today, Baby Smith is the new admit - 24 weeker, honeymooning, Baby Brown just came back from surgery and has been getting transfusions nonstop..." so that we know what the major news is and what nurses might need an extra hand or two that shift. She'll tell us what kinds of babies are in L&D so we know what kind of admissions we might be in for and also what doctors are currently on call. She'll also make unit announcements at this time - like if there are any big unit changes or news, if we're collecting money for a gift for a staff member, etc.
This report takes 10 minutes or so, and then we go get bedside report.
