Abstract

Objective: The purpose of the study was to examine calories administered to inpatients over 90 years of age.

Subjects and Methods: The results of nutrition support team (NST) interventions for 294 elderly patients aged 90 years or older who were evaluated at least 4 times over at least 21 days from April 2008 to March 2022 were investigated retrospectively. The Geriatric Nutritional Risk Index (GNRI) was compared at the first and last NST session. The subjects were divided into three groups with an increased (n = 161), unchanged (n = 9), and decreased (n = 124) GNRI. The recommended calories, achievement of these calories, and the nutritional intake at the last session were compared among the groups.

Results: There was no significant difference in the recommended calories among the groups, but the achievement rate and intake differed significantly between cases with increased and decreased GNRI. In these respective groups, the recommended calories were 999.4 and 994.0 kcal, the achievement rates were 99.7% and 88.2% (p < 0.01), and the intakes were 1,003.1 and 879.9 kcal (p < 0.01).

Conclusion: The optimal intake of calories to avoid a risk of decreased nutrition in inpatients aged 90 years or older is suggested to be about 1,000 kcal.
