What does a nutritional risk screening score of 5 mean

A nutritional risk screening score of 5 means that the patient is at nutritional risk and should be prepared for nutritional supportive therapy at this time. Clinically, NRS2002 is usually used to conduct nutritional risk screening. On the one hand, the doctor will ask the patient's nutritional status, and the patient's recent reduced intake, BMI (body mass index) <20.5, weight loss, and ICU admissions indicate that the patient is at nutritional risk. Subsequently, the doctor will conduct a final screening of patients at nutritional risk, asking whether the patient's intake has been reduced by 1/4, 1/2, or is basically unable to eat; whether the patient has a chronic disease, bone fracture, pneumonia, etc.; whether the patient needs to undergo surgical treatment or chemotherapy; and whether the patient is 70 years of age or older.
