Notes
  • Outcomes apply to general and vascular surgery patients.
  • Other types of surgery may have higher or lower rates.[3]
  • Patients with SAS ≤4 have a high risk of postoperative ICU admission.[4]
  • For additional information on SAS, refer to UpToDate topics discussing perioperative outcomes.
  • ICU: intensive care unit.
