The New Jersey Bowel Preparation Scale: A More Objective and Detailed Scoring System for Screening Colonoscopies

Table 1

A table demonstrating the New Jersey Bowel Preparation Scale Scoring System.

(a)

	0—residual material present in less than 1 quadrant of the image or completely clear. This represents the best (most clean) score for a given segment.
	25—residual material present in at least 1 but less than 2 quadrants. No solid stool is present in any quadrant.
	50—residual material present in at least 2 quadrants or solid stool in any quadrant. This represents the worst (least clean) score for a given segment.

(b)

Total score: average segment score [(left colon + transverse colon + right colon)/3]; Penalty score: add 15 to total score if aspirate volume more than 500 cc
Total score	Description	Recommendation for repeat colonoscopy
0-15	Good	Follow guidelines
15-30	Fair	3-5 years
30-45	Mediocre	1-3 years
>45	Poor	1 year or as soon as possible

Example score: total score: (left colon score: 50 + transverse colon score: 25 + right colon score: 0)/3 = 25, penalty score: 330 cc aspirate, no penalty score needs to be added, total , which equates to fair bowel prep, with recommendation for repeat, colonoscopy in 3-5 years.
