Why the study?
Emergent surgery decisions in nonagenarians are complex due to outcome uncertainties, and the performance of the ACS-NSQIP risk calculator in this population was uncharacterized.
What are the predictors of mortality and the accuracy of the ACS-NSQIP risk calculator in nonagenarian patients undergoing emergency general surgery?

ACS-NSQIP calculator underestimates mortality in nonagenarian EGS; leaves open need for age-specific models before routine use.
What are the predictors of mortality and the accuracy of the ACS-NSQIP risk calculator in nonagenarian patients undergoing emergency general surgery?
The ACS-NSQIP surgical risk calculator significantly underestimates 30-day mortality in nonagenarians undergoing emergency general surgery, particularly in those with recent weight loss combined with steroid use or septic shock.
