Abstract
Background: Malnutrition is highly prevalent in hospitalized older adults and is associated with adverse clinical outcomes. However, the extent to which nutritional care is systematically implemented and its relationship with outcomes remains unclear.
Methods: We conducted a retrospective analysis of 4963 patients aged ≥65 years who were admitted to the National Institute for Health and Scientific Research for the Elderly (IRCCS INRCA, Ancona, Italy) between 2012 and 2020 and received at least one nutritional consultation. We examined associations between timing and type of nutritional interventions, the Geriatric Nutritional Risk Index (GNRI), and clinical outcomes, including in-hospital mortality and length of hospital stay (LOS). We also analyzed the prevalence of different complications during Medical Nutritional Therapy (MNT).
Results: Only 11% of hospitalized patients received a nutritional consultation. Among them, in-hospital mortality was 35.8%. The Geriatric Nutritional Risk Index was a significant predictor of mortality (HR 1.89; 95% CI: 1.55-2.31; p < 0.001) and inversely associated with LOS, reflecting a frail subset of patients with complex clinical conditions. The timing of nutritional consultation showed no significant association with mortality or LOS, possibly due to relatively prompt intervention (median 4 days). Enteral (EN) and parenteral nutrition (PN) were more frequently prescribed to non-survivors. Medical nutrition therapy-related complications were also more common in non-survivors (22.3% vs. 14%, p < 0.001). Artificial nutrition (AN) was not associated with increased mortality, but it was associated with prolonged hospital stays both in survivors and in non-survivors.
Conclusions: Our findings highlight the limited use of nutritional consultations in hospitalized elderly patients despite the high prevalence of malnutrition and its prognostic relevance. The GNRI is a valuable tool for early risk stratification and clinical decision-making. Systematic screening and timely nutritional intervention, integrated with broader therapeutic goals, may improve care and optimize outcomes even in this vulnerable population.
期刊介绍：
Nutrients (ISSN 2072-6643) is an international, peer-reviewed open access advanced forum for studies related to Human Nutrition. It publishes reviews, regular research papers and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced.
