RT Journal Article SR Electronic T1 Risk stratification tools in emergency general surgery JF Trauma Surgery & Acute Care Open FD BMJ Publishing Group Ltd SP e000160 DO 10.1136/tsaco-2017-000160 VO 3 IS 1 A1 Joaquim Michael Havens A1 Alexandra B Columbus A1 Anupamaa J Seshadri A1 Carlos V R Brown A1 Gail T Tominaga A1 Nathan T Mowery A1 Marie Crandall YR 2018 UL http://tsaco.bmj.com/content/3/1/e000160.abstract AB The use of risk stratification tools (RST) aids in clinical triage, decision making and quality assessment in a wide variety of medical fields. Although emergency general surgery (EGS) is characterized by a comorbid, physiologically acute patient population with disparately high rates of perioperative morbidity and mortality, few RST have been explicitly examined in this setting. We examined the available RST with the intent of identifying a tool that comprehensively reflects an EGS patients perioperative risk for death or complication. The ideal tool would combine individualized assessment with relative ease of use. Trauma Scoring Systems, Critical Care Scoring Systems, Surgical Scoring Systems and Track and Trigger Models are reviewed here, with the conclusion that Emergency Surgery Acuity Score and the American College of Surgeons National Surgical Quality Improvement Programme Universal Surgical Risk Calculator are the most applicable and appropriate for EGS.
