Mental Stress and Bowel Preparation Quality

Study Overview
=================
Brief Summary
-----------------
The goal of this cross-sectional study was to explore the relationship between physical and psychological stress and the quality of bowel preparation before a colonoscopy examination, in order to improve the quality of bowel preparation. The main questions it aims to answer are: Does physical and psychological stress affect the quality of colonoscopic bowel preparation, and delay disease detection? How can we improve the quality of colonoscopy？ Participants will be asked to complete a questionnaire containing their demographics, history of diseases and drugs, lifestyle habits, and physical and 14-item perceived stress scale(PSS-14). Quality of bowel preparation was assessed by the Boston bowel preparation scale（BPS）.

Detailed Description
-----------------
A total of 1000 patients who were to undergo colonoscopy at the Endoscopy Centre of the Department of Gastroenterology, Renji Hospital, from May 2023 to August 2023 were collected, and the general information and the physical and mental stress test scale of the patients were collected by questionnaires from random samples, and they were screened for enrolment according to the inclusion and exclusion criteria. The correlation between physical and mental stress and the quality of bowel preparation for colonoscopy was analyzed according to the Boston Rating Scale (BPS), which is used by colonoscopists to assess the quality of bowel preparation for each patient.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The quality of bowel preparation | Quality of bowel preparation was assessed by the Boston bowel preparation scale(BPS). The BPS is used to assess the quality of bowel preparation on a 9-point scale. The colon is divided into three sections (right-sided colon, transverse colon and left-sided colon) and each segment is scored on a four-point scale (0-3), with higher scores indicating a cleaner bowel. The total Boston score is 9, with a score of less than 6 indicating poor bowel preparation. | During colonoscopy, about 20 minutes |
