Nutritional Risk and Assessment for Patients with Cancer Pain

Abstract

Both NRS-2002 and PG-SGA could identify patients with nutritional risk and malnutrition accurately. NRS-2002 is simpler and takes less time to finish, while PG-SGA is more cumbersome with a higher detection rate of malnutrition. NRS, PA, TP and BMI are the most important reference indicators predicting on nutritional risk index and malnutrition status. We recommend NRS-2002 ≥ 2 as the diagnostic criteria in order to avoid missing the patients with nutritional risk.
