BackgroundAlthough longevity is becoming frequent, there are no scores to assess nonagenarians undergoing emergency surgery. The aim of this prospective observational study was to determine 30-day mortality and the individual performance of the Physiological and Operative Severity Score for Enumeration of Mortality and Morbidity (POSSUM) and other scores in predicting their risk for death.MethodsA total of 126 patients were included (2006-2011) and followed for 30 days. Patients risk for death was calculated using different scores. The accuracy of each score was assessed with exponential and linear methods and using the area under the receiver operating characteristic curve.ResultsOverall mortality was 34.9%. The POSSUM, with a modification in the age category, had an area under the curve of .71 and ratios of observed to predicted deaths of 1.07 and 1.22, respectively, in the linear and exponential analysis.ConclusionsIn a population with as high a risk as nonagenarians, the age-modified POSSUM proved accurate to audit surgery and assess mortality risk.Copyright © 2013 Elsevier Inc.
