A Korean experience of the use of Boston bowel preparation scale: A valid and reliable instrument for colonoscopy-oriented research

Abstract

Background/Aims:Few bowel preparation scales have been validated. The Boston Bowel Preparation Scale (BBPS) is a novel bowel preparation scale in western countries. We validated the BBPS in Korean patients and assessed the relationship between the colon polyp detection rate and BBPS score.Patients and Methods:This study was a prospective, single-center trial. The BBPS is a 10-point scale that assesses bowel preparation after the completion of all cleansing maneuvers. We assessed three segment scores (the right side, transverse section, and left side) and total BBPS scores during screening colonoscopy. In addition, we compared the BBPS scores with clinically meaningful outcomes such as the polyp detection rate and colonoscope withdrawal times.Results:We enrolled 482 screening colonoscopies between January 2011 and January 2012. The mean (± standard deviation [SD]) BBPS score was 8.1 ± 1.1. Higher BBPS scores (≥8 vs <8) were associated with a higher polyp detection rate (44.9% vs. 33.0%, P = 0.042). The BBPS scores were inversely correlated with colonoscope withdrawal times (r = −0.167, P < 0.001).Conclusions:The BBPS is a valid and reliable measure for assessing bowel preparation during colonoscopy in Korean patients. The polyp detection rate is higher in patients with higher BBPS scores than in those with lower BBPS scores during a colonoscopic procedure.

A Randomized, Endoscopist-Blinded, Prospective Trial to Compare the Efficacy and Patient Tolerability between Bowel Preparation Protocols Using Sodium Picosulfate Magnesium Citrate and Polyethylene-Glycol (1 L and 2 L) for Colonoscopy

“…In a follow-up study, we plan to devise ways to confirm the patients' past bowel preparation methods to allow a more meaningful comparative analysis. Additionally, as BBPS is a validated tool for postwash scoring, it would have been better to use a prewash scoring system, such as the Aronchick Bowel Preparation Scale, along with the BBPS [27][28][29][30].…”

Expert opinions and scientific evidence for colonoscopy key performance indicators

“…Little additional benefit of multiple point scales were found with no additional ADR differences between excellent, good and moderate bowel preparation scores 6266 141 150 151 The most widely used scale, the Boston Bowel Preparation Scale,147 152 demonstrated a correlation with ADR where preparation was rated as perfect,153 although this was not confirmed in another recent study 154. No studies directly correlating preparation with PCCRC are available.…”

Shorter waiting times from education to colonoscopy can improve the quality of bowel preparation: A randomized controlled trial

“…However, the rate of missed adenoma (≤5 mm) in segments with BBPS scores of 2 and 3 has not been studied in detail. Another study (15) reported that higher BBPS scores (≥8 vs. <8) were associated with a higher polyp detection rate (44.9% vs. 33.0%, p=.042). Thus, higher BBPS scores are indicative of a more effective colonoscopy with regard to the likelihood of a prolonged procedure time due to liquid fluid suction, greater difficulty for the colonoscopist, and patient discomfort.…”
