I'm asking how does the hospital decide if a neonate is a critical infant (level 9) in my hospital and typically the nurse only cares for 2 level 9 babies or a step down (grower feeder) infant (level 7) in my hospital and typically a 3-4 pt assignment. It also relates to what the hospital can charge for the care. Only certain bed spaces are verified to be level 9 in my hospital. There is suppose to be some rating scale to determine the acuity the infant is based on what he needs: Picc line, vented, isolate...would be a level 9.
