Geriatric nutritional risk index and prognostic nutritional index improves predictive value of postoperative mortality: a large-scale retrospective cohort study.

ABSTRACT:

Background

Malnutrition increases the risk of mortality. However, the predictive role of preoperative nutritional status in postoperative mortality remains underexplored. This study investigates the link between preoperative objective nutritional indices and postoperative mortality across all adult surgical patients and evaluates the predictive value of malnutrition for postoperative mortality.

Methods

This retrospective study included patients aged 18 or older who underwent surgery. Nutritional status was assessed using the Geriatric Nutritional Risk Index (GNRI) and the Prognostic Nutritional Index (PNI). Logistic regression analysis was performed to explore the relationship between preoperative nutritional status and postoperative mortality and to evaluate the predictive
