Table 2 Components and interpretation of nutrition screening tools

NST	NRS-2002[9]	MUST[9]	NRI[27]	MIRT[8]	SaskIBD-NR[35]
NST components
	Initial screening	BMI	Serum albumin	BMI	Symptoms (nausea/vomiting/diarrhea/poor appetite > 2 wk)
	BMI	Weight loss (last 3-6 mo)	Present weight/usual weight	Weight loss (last 3 mo)	Weight loss (last month)
	Weight loss (last 6 mo)	Acute disease effect3		CRP	Anorexia
	Dietary intake (last week)				Food restriction
	ICU patient
	Final Screening1
	Weight loss
	Food intake
	Disease severity2
NST score indicating risk of malnutrition
	0 = Low	0 = Low	> 97.5 = No Risk	Score range = 0-8	0-2 = Low risk
	1 = Mild	1 = Medium	83.5-97.5 = Moderate	0 = Lowest	3-4 = Medium risk
	2 = Moderate	≥ 2 = High	< 83.5 = High	8 = Highest	≥ 5 = High risk
	≥ 3 = High

¹To be conducted if there is a “YES” to any one of initial screening questions;

²Categorized into mild/moderate/severe based on descriptors in Nutrition Risk Screening 2002 Tool;

³Patient is acutely ill AND there has been/likely to be no nutrition intake > 5 d. BMI: Body mass index; CRP: C-reactive protein; ICU: Intensive care unit. NST: Nutrition screening tools; NRS-2002: Nutrition Risk Screening 2002; MUST: Malnutrition universal screening tool; NRI: Nutritional Risk Index; MIRT: Malnutrition Inflammation Risk Tool; SaskIBD-NR: Saskatchewan Inflammatory Bowel Disease Nutrition Risk.
