Use of These Criteria
Patients should be placed in one class from each of three major categories: I Severity of Signs and Symptoms; II Severity of Renal Functional Impairment; and III Level of Performance. In each major category, the user should select the highest class whose criteria are fulfilled.For example, a patient would be graded as II-C-1 if signs and symptoms fit class II under Severity of Signs and Symptoms, if the creatinine clearance is 30% of predicted normal, and if all usual types of physical activity can be carried out. If the patient is unable to carry out his or her usual types of most strenuous physical activity, the classification would be II-C-2.
