I have worked in longterm care in both the state of Illinois and Missouri, and it is common practice to cross out an old order that is written in the little boxes to the side and to write dc'd or changed and the date, and then to write a new order and this will stop the old order from reoccuring when you get your new Mar, Tar from the pharmacy. It shows that the order has been changed or dc'd and that there is a new order but a date should be written when you see the line to indicate when the order was stopped. we do not cross out the original written order that is written on the right side of the P.O.S. sheet. only the order that is rewritten in the boxes on the left. I hope this makes since and helps. and when i say cross out i mean a single line diagonally, not scribbles or anything else. we are not allowed to use highlighters on mars where i have worked
