ICU Gastrointestinal Dysfunction Score of Aperstein et al

Description

Aperstein et al used a simple score to grade the severity of gastrointestinal dysfunction for a patient in the intensive care unit (ICU). Scaling is based on that of the SOFA score. The authors are from Rabin Medical Center and Afeka Tel Aviv Academic College of Engineering in Tel Aviv.

Patient selection: ICU

Parameters:

(1) resting energy expenditure (REE) daily balance, as difference between caloric target and the number of calories administered

(2) gastric residual volume and/or vomiting

(3) bowel movement

Parameter	Finding	Points
REE daily balance	< - 3,000 kcal/day	4
	-2,001 to -3,000	3
	-1,001 to -2,000	2
	-500 to -1,000	1
	-1 to -499	0
	0 to 500	1
	501 to 1,000	2
	1,001 to 2,000	3
	> 2,000	4
gastric residual volume or vomiting	small amount (< 150 mL)	0
	150 to 500 mL	1
	> 500 mL	2
	vomiting	2
	bloody or fecal vomiting	4
bowel movements	formed	0
	soft	1
	fecal blocks; stool to ileostomy or colostomy;	2
	no bowel movements	3
	small quantity of diarrhea	1
	large amount diarrhea	2
	requires bowel management system	3
	requires rectal tube	4
	small amount of melena	3
	large quantity of melena; frank hematochezia	4

score for GI findings =

= SUM(points for all of the parameters)

Interpretation:

• minimum GI subscore: 0

• maximum GI subscore: 12
