Impact of in-hospital body mass index variation on 28-day mortality in critically ill surgical patients: a multi-center retrospective analysis

Key Points

A moderate reduction in body mass index correlates to the lowest risk of 28-day mortality in critical care.
Patients with a BMI change of -1.75 kg/m² showed significant differences in mortality rates, indicating a crucial measure in treatment.

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.

Abstract

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.
