Predictive value of geriatric nutritional risk indexes for hospital readmission and mortality in older patients

Abstract

The Geriatric Nutritional Risk Index (GNRI) plays a crucial role in assessing nutritional status and predicting clinical outcomes in older patients. This study explores the GNRI as a prognostic tool for clinical outcomes in older inpatients. Spanning from August 2013 to December 2020, the research involved 573 older patients at Tianjin Third Central Hospital, China. The study assessed the association of GNRI with 6-month hospital readmission and 3-year all-cause mortality rates. Our findings reveal that higher GNRI scores significantly correlate with reduced hospital readmissions and mortality, underscoring the utility of GNRI in predicting clinical outcomes and guiding interventions in geriatric care. The study highlights the potential of integrating GNRI assessments into routine clinical evaluations to enhance patient care and optimize resource utilization in healthcare settings.
