Association between indication for therapy by nutrition support team and nutritional status.

The nutrition support team is a multidisciplinary team composed of medical doctors, registered nurses, pharmacists, and nutritionists, who evaluate the nutritional status of patients. The objective of this study was to determine the relationship between indications for nutrition support team therapy and the nutritional status of patients hospitalized in local major hospitals.Patients who were referred to a nutrition support team from January to December 2016 were enrolled. Patients were classified into 4 age groups, and the weight categories were determined using body mass index (BMI). Four of 6 indications were used for referral to a nutrition support team. The required calories were estimated, and the nutritional status was classified into malnutrition or eutrophia, based on the estimation.The proportion of elderly patients (37.0%) was higher than that of younger ones (28.3%). Patients with higher BMI had a relatively lower proportion of malnutrition. Patients receiving enteral nutrition had greater risk of malnutrition (adjusted odds ratio [aOR] = 3.77, 95% confidence interval [CI] = 2.71-5.24). Patients receiving parenteral nutrition (aOR = 0.38, 95% CI = 0.30-0.47) and treated in the intensive care unit (aOR = 0.70, 95% CI = 0.54-0.91) had lower risk of malnutrition. Patients with >3 indications for nutrition support team therapy had a lower risk of malnutrition than those with only 1 indication (aOR = 0.54, 95% CI = 0.37-0.77).Parenteral nutrition was the most common indication for referral to nutrition support team therapy; however, enteral nutrition had the poorest nutritional status. Patients receiving enteral nutrition who are referred to a nutrition support team need an intensive nutrition support strategy.
