Predictive performance was assessed for 28\u2010day mortality, post\u2010operative complications, intensive care unit (ICU) admission, and hospital length of stay (LOS). C\u2010statistics were used to compare ESAS with P\u2010ESAS and other scoring systems, including the Charlson Comorbidity Index (CCI). Logistic regression models were employed to identify independent predictors of 28\u2010day mortality, incorporating clinically relevant covariates such as demographic characteristics, comorbidities, physiological parameters, and surgical factors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The ESAS and P\u2010ESAS demonstrated superior predictive abilities compared to the Charlson Comorbidity Index (CCI) across clinical outcomes. For 28\u2010day mortality, the c\u2010statistics were 0.917 for ESAS, 0.897 for P\u2010ESAS, and 0.691 for CCI. Both ESAS and P\u2010ESAS outperformed CCI in predicting post\u2010operative complications (c\u2010statistics: 0.701, 0.677, and 0.637, respectively) and ICU admission (c\u2010statistics: 0.777, 0.737, and 0.645, respectively).
