肠道准备合格率

指标类型:

主要指标

Outcome:

Rate of adequate bowel preparation

Type:

Primary indicator

测量时间点:

肠道准备结束后、进行结肠镜检查时

测量方法:

研究采用波士顿肠道准备评分(BBPS)量化受试者的肠道准备质量,合格的肠道准备定义为 BBPS≥6 分,且每段肠道的评分均≥2 分。肠道准备合格的人群占受试总人群的比例即为肠道准备合格率。

Measure time point of outcome:

After completion of bowel preparation and at the time of colonoscopy

Measure method:

The study used the Boston Bowel Preparation Scale (BBPS) to quantify the quality of bowel preparation in subjects. Adequate bowel preparation was defined as a total BBPS score ≥6, with each segment score ≥2. The proportion of subjects achieving adequate bowel preparation out of the total study population was defined as the adequate bowel preparation rate.

测量方法:

波士顿肠道准备评分量表一共分为3个肠段(盲肠+升结肠、横结肠、降结肠+乙状结肠+直肠)、4个等级评分标准,每个肠段的评分范围0~3分,总分为0~9分。

Measure time point of outcome:

After completion of bowel preparation and at the time of colonoscopy

Measure method:

The Boston Bowel Preparation Scale (BBPS) divides the colon into three segments: the right colon (cecum and ascending colon), the transverse colon, and the left colon (descending colon, sigmoid colon, and rectum). Each segment is scored on a 4-point scale ranging from 0 to 3, and the total score ranges from 0 to 9.
