How is the ASA physical status classification used in ASC patient selection?

• A. It classifies patients from ASA I to ASA VI to help determine perioperative risk and suitability for outpatient surgery
• B. It grades injuries
• C. It determines payment
• D. It sets surgical time slots

Answer: (D)

ASA physical status is a preoperative risk stratification tool that reflects a patient’s overall health before surgery, ranging from healthy (I) to moribund (VI). In ambulatory surgery centers, this classification helps determine if a patient can safely undergo same-day discharge and what level of perioperative monitoring and resources they’ll need. Lower ASA classes generally indicate lower risk and are more suitable for outpatient procedures, while higher ASA classes signal greater risk and may lead to additional preoperative optimization, more careful anesthesia planning, and possible inpatient admission. This tool guides decisions about patient selection and perioperative planning, not about injury grading, payment, or scheduling time slots.
