Immune-nutritional indicators effectively predict short-term mortality in older surgical patients.

An analysis of 4,120 older patients indicated that immune-nutritional indicators, including the mgps, pni, and conut score, are effective in predicting 90-day postoperative survival after emergency gastrointestinal surgery. ROC curves demonstrated strong predictive power with an AUC of 0.68 for all models assessed. Notably, high-risk scores from the lasso cox model correlated with worse outcomes. A nomogram developed from key variables achieved a c-index of 0.706, enhancing patient risk assessment.
