So the previous LTC place I worked in, they have a Coumadin sheet that tells the recent dose, the date it was ordered and the next INR date. The MAR was in grid form and we basically put a line on days before and after the date range of when the Coumadin should be given and write INR on the date it is ordered to be drawn. That way, you have a constant reminder of your coumadins and INR draw dates.
