Hello Dfisher, I work in a large medical center in KSA and use the patient acuity scale in the ICU and the wards. In our acuity scale, we assess the current needs of a patient, how much load of nursing a patient needs and the acuity would tell how critical a patient is or how self-caring a client may be. I shall send you reply once I get a copy of how the acuity scale looks like. I hope I was able to help...a bit. Have a nice day
