Lim et al developed a simple nutrition screening tool for patients being admitted to the hospital. The nutritional assessment can be completed within 3 minutes. The authors are from National University Hospital, Princess Alexandra Hospital, National Healthcare Group, Singapore Clinical Research Institute and Queensland University of Technology (Australia).
Patient selection: acute hospital admission
Parameters:
(1) unintentional weight loss in past 6 months
(2) nutritional intake in past week

total score =
= SUM(points for 3 parameters)
Interpretation:
• minimum score: 0
• maximum score: 9
• A score >= 5 indicates severe malnutrition.
• A score of 3 or 4 indicates risk of moderate malnutrition.
Performance:
• For a cutoff of >= 3 to indicate risk of malnutrition, the sensitivity was 86% and specificity 83%.
• For detection of severe malnutrition the sensitivity was 93% and specificity 86%.
