PESAS and 30\u2010day mortality were calculated for all patients. Discrimination of PESAS for 30\u2010day mortality was assessed using area under receiver operator curve (AUROC). Secondary analysis was conducted in similar fashion for the outcome of anastomotic leak requiring reoperation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In 1086 patients with 160 cases of 30\u2010day mortality (14.7%), PESAS showed strong discrimination for the primary outcome (AUROC 0.86; 95% CI 0.83\u20130.88) with acceptable calibration\u2010in\u2010the\u2010large. In an exploratory secondary analysis of 414 patients who received bowel anastomosis with 21 cases of leak (5.1%), PESAS also showed good discrimination for anastomotic leak (AUROC 0.82; 95% CI 0.73\u20130.90). Observed mortality rates showed clear inflection points at PESAS values of 5 and 10, respectively, corresponding to mortality exceeding 10% and 50%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>PESAS demonstrates good discrimination, calibration\u2010in\u2010the\u2010large, and net benefit as an ordinal risk stratification tool for prediction of 30\u2010day mortality among patients undergoing emergency laparotomy, with exploratory analysis suggesting promise for predicting anastomotic leak.
