Sum SSM, et al. – Researchers compared the 7–point subjective global assessment (SGA) and the protein energy wasting (PEW) score with nutrition evaluations conducted by registered dietitian nutritionists in identifying PEW risk in stage 5 chronic kidney disease patients on maintenance hemodialysis. Data highlighted the potential of both the 7–point SGA and the PEW score to identify PEW risk. It was found that the 7–point SGA was more specific, and the PEW score was more sensitive. In identifying patients who were actually not at PEW risk, both scoring tools were found to be clinically confident.
