In-hospital BMI change is a significant predictor of 28-day mortality in surgical ICU patients, suggesting dynamic BMI monitoring may enhance risk stratification and guide fluid management.

Resumen

In-hospital BMI change is a significant predictor of 28-day mortality in surgical ICU patients admitted via the ED. A moderate reduction in BMI (-1.75 kg/m2) was associated with the lowest mortality risk. Dynamic BMI monitoring may enhance risk stratification and guide personalized fluid management in this population.
