Nutritional status and the performance of multiple bedside tools for nutrition assessment among patients waiting for liver transplantation: A Canadian experience

Summary Background Malnutrition is an important predictor of morbidity and mortality among cirrhotic patients. Our objectives were to assess protein-calorie malnutrition (PCM) in cirrhotic pre-liver transplant patients and to study the correlation between subjective global assessment (SGA) and other objective measures of malnutrition. Methods We recruited pre-liver transplant adult patients at our center between October 2012 and Oct 2015. Nutrition status was assessed via SGA. PCM was assessed by comparing recommended to actual protein and calorie intake. SGA was correlated with body mass index (BMI), dry BMI, handgrip strength by calibrated dynometer (HGS), and mid-arm circumference (MAC). We used non-parametric statistical methods in our analysis. Results Seventy patients were included in this study. Majority were males (n = 46, 66%) with a median age of 58 years (IQR: 50-61). Moderate to severe malnutrition was prevalent in our cohort (SGA-A: n = 15 (21.4%), SGA-B: n = 30 (42.9%) and SGA-C: n = 25 (35.7%). There was a significant difference in the recommended calories consumed between SGA groups (A 98.5% vs. C 79.2%, P = 0.03). A similar trend was observed for the recommended protein consumed (A 85.4%, C 62.5%; P = 0.09). SGA correlated with BMI (A = 26.4, C = 22.4; P
