Background and Objective: Nutritional screening upon hospital admission is important to ensure prompt and effective interventional management and to reduce the incidence of hospital complications. This study aimed to screen and evaluate the nutritional status of patients admitted to a tertiary care centre using the Short Nutritional Assessment Questionnaire (SNAQ) and to assess the relationship between malnutrition and length of hospital stay. Materials and Methods: One thousand patients were recruited from the medical wards of Kasr Al Ainy Hospital. All enrolled patients were screened for malnutrition using the SNAQ. Body mass index (BMI), haemoglobin and albumin levels were measured. The predictors of hospital stay were assessed. Results: Of the 1000 patients, 522 (52.2%) were male and their ages ranged from 18-97 years. The median (IQR) BMI was 25.9 (22.8-29.4). A total of 550 patients were malnourished, with SNAQ scores ≥2. The frequency of anaemia and hypoalbuminemia differed significantly in malnourished patients (SNAQ≥2) from that in non-malnourished patients (p<0.001). A long hospital stay was significantly associated with higher SNAQ scores (r = 0.318, p≤0.001) and was inversely associated with BMI and albumin, while a low BMI was the most independent predictor of a long hospital stay (95% CI for the beta coefficient=0.125-0.033). Conclusion: The SNAQ is a simple and quick tool for screening malnutrition risk among hospitalized patients.
