Objective: To evaluate the scored Patient-Generated Subjective Global Assessment (PG-SGA) as a nutrition assessment tool in hemodialysis patients.

Design: A cross-sectional observational study assessing the nutritional status of hemodialysis patients.

Setting: Private tertiary Australian hospital.

Subjects: Sixty patients, ages 63.9 +/- 16.2 years.

Intervention: Scored PG-SGA questionnaire, comparison of PG-SGA score > or =9 with subjective global assessment (SGA), albumin, corrected arm muscle area, and triceps skinfold.

Results: According to SGA, 80% of patients were well nourished and 20% of patients were malnourished. Patients classified as well nourished (SGA-A) attained a significantly lower median PG-SGA score compared with those rated as moderately malnourished or at risk of malnutrition (SGA-B). A PG-SGA score > or =9 had a sensitivity of 83% and a specificity of 92% at predicting SGA classification. There were significant correlations between the PG-SGA score and serum albumin, PG-SGA score, and percentage weight loss over the past 6 months. There was no association between PG-SGA score and body mass index or anthropometric measurements.

Conclusion: The scored PG-SGA is an easy-to-use nutrition assessment tool that allows quick identification of malnutrition in hemodialysis patients.

Reference work for leading, current and selected literature in the field of clinical nutrition

Publications on clinical nutrition have grown steadily in recent years and the scientific evidence has been improved by numerous observational as well as intervention studies. Various umbrella organisations, such as the Swiss Society for Clinical Nutrition (GESKES), the German Society for Nutritional Medicine (DGEM) or the European Society for Clinical Nutrition and Metabolism (ESPEN) publish guidelines on nutrition in various clinical situations at regular intervals. Thus, a large amount of literature is available for evidence-based nutritional medicine.

The NutriBib aims to filter out authoritative publications in the various fields of nutritional medicine and thus to provide an overview of the abundance of literature. A large number of experienced nutrition experts contributed to the selection of relevant sources and allow a broadly based selection. Nevertheless, the literature selection cannot be considered exhaustive. Specific literature can be found by entering search words (using the magnifying glass at the top right) or by searching the table of contents.
