Malnutrition is a commonly found risk factor in hospitalized patients. All hospital patients, especially the high-risk ones, should be offered nutritional screening. Methods of screening include MUST (Malnutrition Universal Screening Tool) and the patient should have a thorough clinical assessment and investigations. The patient should meet adequate calorie requirement either by oral or enteral or parenteral nutrition. Malnourished patients receiving nutrition supplements demonstrated lower infection rates and shorter length of hospital stay compared to no supplements.
