Abstract

BACKGROUND

The Boston Bowel Preparation Scale (BBPS) is a novel bowel cleanliness rating scale that has undergone partial validation previously.

OBJECTIVE

To fully validate the BBPS and assess the ease of its dissemination.

DESIGN

Observational study.

SETTING

Various endoscopy units worldwide.

SUBJECTS

Endoscopists.

METHODS

Video recordings of colonoscopies with varying degrees of cleanliness were viewed twice by gastroenterologists at 1 medical center. For each video, participants assigned segment and total BBPS scores. Endoscopists worldwide were also surveyed about their experience with the BBPS after viewing an instructional video.

MAIN OUTCOME MEASUREMENTS

Intraclass correlation coefficients and weighted κ values assessed inter- and intrarater reliability, respectively. The BBPS was used among 983 patients undergoing screening colonoscopy.

RESULTS

The BBPS demonstrated near-perfect interrater reliability (intraclass correlation coefficient = 0.91) and substantial intrarater reliability (weighted κ = 0.78; 95% CI, 0.73-0.84). Among 983 colonoscopies, right and left colon segment scores of 2 or 3 had a multivariate odds ratio of 1.60 (95% CI, 1.01-2.55) and 2.58 (95% CI, 1.34-4.98), respectively, for polyp detection compared with segment scores of 0 or 1. Endoscopists from a variety of settings worldwide found the BBPS easy to implement and applicable to their patient population.

LIMITATIONS

Single-center reliability testing.

CONCLUSIONS

The BBPS is a valid and reliable instrument for assessing bowel cleanliness during colonoscopy. Segment scores may represent a standardized way to determine bowel preparation adequacy. The BBPS can be easily disseminated through the use of a brief instructional video.

摘要

背景

波士顿肠道准备量表（BBPS）是一种新颖的肠道清洁评分量表，之前已经进行了部分验证。

目的

全面验证 BBPS 并评估其传播的容易程度。

设计

观察性研究。

设置

全球各地的各种内镜单位。

受试者

内镜医师。

方法

在 1 家医疗中心，由胃肠病学家两次观看清洁度不同的结肠镜检查的视频记录。对于每个视频，参与者分配节段和总 BBPS 评分。在观看教学视频后，全球的内镜医师还被调查了他们对 BBPS 的使用经验。

主要观察指标

组内相关系数和加权κ值分别评估了组内和组间的可靠性。该量表用于 983 例接受筛查性结肠镜检查的患者。

结果

BBPS 显示出近乎完美的组间可靠性（组内相关系数=0.91）和实质性的组内可靠性（加权κ=0.78；95%CI，0.73-0.84）。在 983 例结肠镜检查中，右结肠和左结肠节段评分为 2 或 3 的患者，与评分 0 或 1 的患者相比，检测到息肉的多变量优势比分别为 1.60（95%CI，1.01-2.55）和 2.58（95%CI，1.34-4.98）。来自世界各地各种环境的内镜医师发现 BBPS 易于实施且适用于他们的患者人群。
