Geriatric Nutritional Risk Index as a Screening Tool for Malnutrition in Patients on Chronic Peritoneal Dialysis

Although GNRI is significantly correlated with other nutritional indices, it is not sensitive for screening malnutrition in PD patients. Serial measurements of GNRI are also not sensitive in detecting a change in nutritional status. Further study is needed to identify a simple and reliable tool for the assessment and monitoring of nutritional status in PD patients.
