Although age per se is not a factor in determining candidacy for ambulatory procedures, each patient must be considered in the context of his or her comorbidities, the type of surgery to be performed, and the expected response to anesthesia. First developed in 1963, the American Society of Anesthesiologists’ (ASA) physical status classification system (Table 66-1) summarizes the physiologic fitness of each patient prior to surgery. It serves as a means of communication between health-care providers and is used for record-keeping.
