Abstract

BackgroundThe performance of the Emergency Surgery Score (ESS), a validated risk calculator, in the elderly emergency general surgery (EGS) patient remains unclear. We hypothesized that ESS accurately predicts outcomes in elderly EGS patients, including octogenarians and nonagenarians. MethodsUsing the 2007–2017 National Surgical Quality Improvement Program (NSQIP) database, we included all EGS patients ≥65 years old. The correlation between ESS, mortality and morbidity was assessed in the 3 patient cohorts (>65, octogenarians and nonagenarians), using the area under the curve (AUC). ResultsA total of 124,335 patients were included, of which 34,215 (28%) were octogenarians and 7239 (6%) were nonagenarians. In patients ≥65 years, ESS accurately predicted mortality (AUC 0.81). For octogenarians and nonagenarians, ESS predicted mortality moderately well (AUC 0.77 and 0.69, respectively. ConclusionESS accurately predicts mortality and morbidity in the elderly EGS patient, but its accuracy in predicting morbidity decreases for nonagenarians.
