Association between the geriatric nutritional risk index and all-cause mortality in older critically ill patients with community-acquired pneumonia.

ABSTRACT:

Aim

This study aimed to explore the association between the geriatric nutritional risk index (GNRI) and the risk of mortality in critically ill older patients with community-acquired pneumonia (CAP).

Methods

This retrospective study included 1924 critically ill patients with CAP from the Medical Information Mart for Intensive Care-IV3.1 (MIMIC-IV3.1) database. The participants were grouped into four groups based on GNRI levels. The clinical outcome was 30-day, 90-day, 180-day, and 1-year mortality. Cox proportional hazards regression analysis and restricted cubic spline regression were used to evaluate the association between the GNRI and clinical outcomes in critically ill older patients with CAP.

Results

A total of 1924 patients (56.9% male) were included in the stu
