Association between the geriatric nutritional risk index and adverse post-extubation outcomes for critically ill older adults: a retrospective study.

ABSTRACT:

Background and purpose

Malnutrition commonly predicts adverse outcomes among older adults in the intensive care unit (ICU). The Geriatric Nutritional Risk Index (GNRI) is a simple and practical tool for assessing nutritional status in older adults. This study aims to explore the association between GNRI and adverse post-extubation outcomes in critically ill older adults.

Methods

A total of 1,153 older adults aged 65-82 years in the ICU were included in this retrospective cohort study. GNRI categories were stratified into four subgroups based on nutritional risk: major risk (GNRI < 82), moderate risk (GNRI 82-91), low risk (GNRI 92-98), and no risk (GNRI > 98). Adverse post-extubation outcomes included mortality or pneumonia within 30 days post-extubation, reintubation within
