Association of the geriatric nutrition risk index with mortality in critically ill patients with heart failure: a retrospective cohort study.

ABSTRACT:

Background

The prognostic value of the geriatric nutrition risk index (GNRI) in critically ill patients with heart failure (HF) remains unclear, despite its established association with mortality in critically ill patients with HF.

Objective

To investigate the association between GNRI and mortality and evaluate the additive value of GNRI for predicting mortality in critically ill patients with HF.

Methods

This retrospective cohort study analysed 4058 patients aged ≥65 years with HF from the Medical Information Mart for Intensive Care IV database. GNRI was categorised into GNRI >98 (no malnutrition risk) and GNRI ≤98 (at risk of malnutrition). Associations between GNRI and in-hospital, 30-day and 1-year mortality were evaluated using logistic regression, Cox proportion
