AIM: We sought to investigate whether the Geriatric Nutritional Risk Index is associated with systemic organ dysfunction among older patients who present with cholecystitis to the emergency department. METHODS: This was an observational retrospective study among consecutive older patients with cholecystitis in the emergency department from 2012 to 2018. We collected baseline characteristics and laboratory data, and re-categorized the Geriatric Nutritional Risk Index into three risk groups. We carried out univariate and multivariate analyses to identify factors associated with systemic organ dysfunction. Logistic regression was used for statistical analysis. RESULTS: A total of 303 patients were included in this study. The median age of participants was 74 years (interquartile range 68-79 years). The overall proportion of systemic organ dysfunction was 26.4%. The Geriatric Nutritional Risk Index was stratified as: ≥98 (n = 183, systemic organ dysfunction 15.3%), 87 to <98 (n = 90, systemic organ dysfunction 38.9%) and <87 (n = 30, systemic organ dysfunction 56.7%). Multivariate analysis using a logistic regression model showed that age, respiratory rate, temperature, geriatric nutritional risk index and quick Sepsis-related Organ Failure Assessment score in the emergency department were independently associated with systemic organ dysfunction in patients with cholecystitis. CONCLUSIONS: The Geriatric Nutritional Risk Index was recognized as an independent factor associated with systemic organ dysfunction in older patients in the emergency department who presented with cholecystitis. This index might be helpful in screening patient risk and deciding whether to carry out further tests. Geriatr Gerontol Int 2020; 20: 455-460.
