We will investigate the details of the nutritional dosage of elderly patients aged 90 years or older who were evaluated by our NST from 2008 to 2021. We will divide them into two groups: those who meet the recommended nutritional dosage and those who do not, and statistically analyze the relationship between the dosage and various factors such as gender, underlying disease, and route of nutritional administration.
For patients who have undergone more than one NST intervention, nutritional doses and nutritional assessments will be compared between the first and second interventions, divided into improvement, invariance, and worsening, and statistically analyzed in relation to various factors.
