Relationship between nutritional status and length of hospital stay in oncological surgery.

Abstract

e13591 Background: In Germany, a serious illness is the main cause of malnutrition. Various studies have already shown that the length of time in hospital for various diseases and operations in malnourished patients increases. This leads to a deterioration in the quality of life of the patient and results in considerable costs for the health care system. Methods: In order to investigate the relationship between nutritional status and length of hospital stay, a patient group of 363 patients who had a tumor with the primary tumor in the gastrointestinal tract was first identified. All patients had an NRS score of 3 or greater and a meaningful laboratory with regard to protein and albumin levels and / or results of a bioelectrical impedance analysis. The average length of stay for these patients was determined depending on the various parameters. Results: The present study shows that malnourished patients have to stay in the hospital for between 2 and 11.1 days longer. When evaluating the NRS score, the protein and albumin level as well as the BCM and the ECM / BCM index, a longer hospital stay of malnourished patients compared to those who were not malnourished was demonstrated. The BMI is an insufficient parameter to describe the nutritional status. An extension of the length of hospital stay cannot be demonstrated only on the basis of the BMI. Conclusions: Since an inadequate nutritional status obviously affects the length of hospital stay in oncological patients, they should be examined early for malnutrition. The length of stay can be shortened through nutritional therapy measures, which also leads to a significant reduction in costs.
