background:The use of enhanced instruction can improve the efficiency of education for bowel preparation regimens. Researchers hypothesized that face-to-face instruction and personalized intervention for inpatient could improve successful bowel preparation rate and patient's compliance with regimens. Methods:This was an endoscopist-blind,randomized controlled trial. 320inpatients were randomized 1:1 in one of the two study groups. The intervention group received face-to-face instruction and personalized intervention for bowel preparation protocol, while control group received the standard bowel preparation protocol. Patients'demographics, bowel preparation quality, colonoscopy completion and attendance were recorded. Logistic regression was performed to identify predictors of bowel preparation failure.

Patients with risk factor : on the day before the colonoscopy at 20:00- 21:00 hours, 60gPEG-4000 was mixed with 1L water; 4-6 h before colonoscopy, 120gPEG-4000 was mixed with 2L water. Patient without risk factor: 4-6 hours before colonoscopy, 120gPEG-4000 was mixed with 3L water. Education completed by experienced researcher.
All patients on the day of the colonoscopy:4-6 hours before colonoscopy, 120gPEG-4000 was mixed with 3L water. Education completed by ward nurse.

Quality of Bowel Preparation
The BBPS is a validated scoring system with scores between 0 and 9, where 9 is the best score. The score comprises a sub score 0-3 for each colon segment: right, transverse and left colon. For all participants, BBPS score will be used when colonscopy is withdrawing.
Time frame: 1 Day of colonoscopy
adverse events
Including nausea, vomiting, abdominal pain and bloating,etc.
Time frame: The day of colonoscopy and the day before
cecal intubation rate
The number of colonoscopy reaching the cecal area divided by the total number of colonoscopy
Time frame: 1 Day of colonoscopy
polyp detection rate
PDR was defined as the number of patients with at least one polyp divided by the total number of colonoscopy patients
Time frame: 1 Day of colonoscopy
cecal intubation time
Time to reach the cecal
Time frame: 1 Day of colonoscopy
withdrawal time
Time from withdrawal from the cecum to the end of colonoscopy
Time frame: 1 Day of colonoscopy
