Screen for malnutrition risk using the Malnutrition Universal Screening Tool (MUST). Step 1: BMI score (above 20 = 0, 18.5-20 = 1, below 18.5 = 2). Step 2: weight loss score (0-5% = 0, 5-10% = 1, above 10% = 2). Step 3: acute disease effect (if acutely ill and no nutrition for more than 5 days, add 2). Total 2 or higher = high risk; 1 = medium risk; 0 = low risk.
