Evaluating the Geriatric Nutritional Risk Index (GNRI) as a Predictor of Mortality in Hospitalized Patients with COVID-19 (72656)
Session: On Demand
Room: Virtual Poster Presentation
Presentation Type:Virtual Poster Presentation
Introduction: Malnutrition can worsen clinical outcomes in older patients, underlying the importance of using a screening tool to detect patients at risk. We evaluated the association between Geriatric Nutritional Risk Index (GNRI) and mortality in elderly patients with COVID-19 infection.
Methods: We evaluated 241 patients aged ≥65y who were admitted with COVID-19 infection to the Toronto General Hospital, Ontario, Canada, between March 2019, and May 2022. Demographic data, BMI, laboratory results, and comorbidities were extracted, and GNRI was calculated as 1.489×serum albumin+41.7×present weight/ideal weight. Logistic regression was conducted to find the odds ratio of mortality for the GNRI groups. Chi-square test was applied to test the dependency between GNRI, mortality and BMI.
Results: From the 241 evaluated patients, 145 (median 79.3; range or quartiles year) had complete longitudinal data collected. The patients were categorized into three groups: severe to moderate risk (GNRI 98, 84 patients). The underweight patients were more likely to fall into the GNRI 98 group. The odds of mortality was 3.4 (95% CI=1.33-8.92) higher in the GNRI 98 group.
Conclusions: GNRI is associated with BMI and mortality in older patients with COVID-19 infection. In this patient population, it may be a useful screening tool to detect patients at risk for malnutrition and higher mortality. This may assist in providing appropriate
