Our hospital uses the GRASP system. What a joke! It is used to predict staffing needs for the oncoming shift. In reality, it is used to justify understaffing our unit. Our ICU has a swinging door. The bed isn't even cold before the next patient is in it and unless you are God, there is no way possible to determine the level of care that patient will need. What we need is legislation that regulates nurse to patient ratios!
