Matras et al developed a score for evaluating the nutritional status of an adult prior to surgery. This can help to identify a patient who may benefit from a nutritional intervention prior to surgery. The author is from the Medical University of Lublin in Poland.
Parameter:
(1) body mass index in kilograms per square meter
(2) percent loss of body weight over 3 months
(3) decrease in muscle strength
(4) number of bowel movements (evacuations) per day
(5) diabetes mellitus
(6) kidney failure
(7) chronic pancreatitis
(8) cancer
(9) serum albumin in g/dL
(10) serum cholesterol in mg/dL
(11) absolute lymphocyte count in 10^9/L

Interpretation:
• minimum score: 0
• maximum score: 26
• The higher the score the greater the malnurition.
