Description

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

(3) muscle wasting over temple (temporalis muscle) or clavicle

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%.
