Development and validation of a hospital screening tool for malnutrition: the short nutritional assessment questionnaire(SNAQ)

Objective: For the early detection and treatment of malnourished hospital patients no valid screening instrument for the Dutch language exists. Calculation of percentage weight loss and body mass index (BMI) by the nurse at admission to the hospital appeared to be not feasible. Therefore, the short, nutritional assessment questionnaire (SNAQ©), was developed. Research, design and methods: Two hundred and ninety one patients on the mixed internal and surgery/oncology wards of the VU University medical center were screened on nutritional status and classified as well nourished (<5% weight loss in the last 6 months and BMI>18.5), moderately malnourished (5-10% weight loss in the last 6 months and BMI>18.5) or severely malnourished (>10% weight loss in the last 6 months or >5% in the last month or BMI
