很少有肠道准备评分量表经过验证。大多数是用于比较口服泻药的，没有考虑到内镜医师的冲洗/抽吸操作。这限制了它们在结肠镜检查结果（如息肉检出率）研究中的应用。
目的：开发一种用于结肠镜检查结果研究的有效且可靠的量表。
研究地点：学术医疗中心
我们开发了波士顿肠道准备量表（BBPS），这是一个10分制的量表，用于在内镜医师完成所有清洁操作后评估肠道准备情况。我们让22名临床医生在两个不同时间观看结肠镜检查视频片段，以此评估观察者间和观察者内的可靠性。然后我们在筛查性结肠镜检查中前瞻性地应用BBPS，将BBPS评分与包括息肉检出率和操作时间在内的具有临床意义的结果进行比较。
BBPS评分的组内相关系数（一种衡量观察者间可靠性的指标）为0.74。评分的加权卡帕值（一种衡量观察者内可靠性的指标）为0.77（95%置信区间为0.66 - 0.87）。在633次筛查性结肠镜检查中，BBPS评分的平均值（标准差）为6.0（1.6）。较高的BBPS评分（≥5分对比<5分）与较高的息肉检出率相关（40%对24%；p<0.02）。BBPS评分与结肠镜插入（r = -0.16；p<0.003）和退出（r = -0.23；p<0.001）时间呈负相关。
单中心研究
BBPS是一种有效且可靠的肠道准备评估方法。它可能非常适合用于结肠镜检查结果研究，因为它反映了检查过程中结肠的清洁程度。
Few bowel preparation rating scales have been validated. Most were intended for comparing oral purgatives, failing to account for washing/suctioning by the endoscopist. This limits their utility in studies of colonoscopy outcomes such as polyp detection rates. To develop a valid and reliable scale for use in colonoscopy outcomes research. Academic medical center. We developed the Boston Bowel Preparation Scale (BBPS), a 10-point scale assessing bowel preparation after all cleansing maneuvers are completed by the endoscopist. We assessed inter- and intra-observer reliability using video footage of colonoscopies viewed on two separate occasions by 22 clinicians. We then applied the BBPS prospectively during screening colonoscopies, comparing BBPS scores with clinically-meaningful outcomes including polyp detection rates and procedure times. The intra-class correlation coefficient (a measure of inter-observer reliability) for BBPS scores was 0.74. The weighted Kappa (a measure of intra-observer reliability) for scores was 0.77 (95% CI 0.66-0.87). During 633 screening colonoscopies, the mean (SD) BBPS score was 6.0 (1.6). Higher BBPS scores (≥5 versus <5) were associated with a higher polyp detection rate (40% vs 24%; p<0.02). BBPS scores were inversely correlated with colonoscope insertion (r = −0.16; p<0.003) and withdrawal (r = −0.23; p<0.001) times. Single-center study. The BBPS is a valid and reliable measure of bowel preparation. It may be well-suited to colonoscopy outcomes research because it reflects the colon's cleanliness during the inspection phase of the procedure.
