The study compares the efficacy of bowel preparation between the face-to-face re-education(FFRE group) and normal education (no-FFRE group) in patients.
Despite advances in bowel preparation methods,bowel preparation is inadequate in up to one-third of all colonoscopies in reported series.Inadequate bowel cleansing results in negative consequences for the examination, including incomplete visualisation of the colon, missed lesions, procedural difficulties, prolonged procedure time and reduced time interval until follow-up, and an estimated 12-22% increase in overall colonoscopy cost.
The adequacy of a bowel preparation is closely linked to patient compliance with both dietary and purge instructions.One study performed in Asia showed that non-compliance with bowel preparation instructions, lower education level, and a long wait for the colonoscopy appointment were independent risk factors for poor bowel preparation. Another study performed in China showed that telephone re-education（TRE) about the details of bowel preparation on the day before colonoscopy significantly improved the quality of bowel preparation and PDR. So,it is reasonable to hypothesise that efforts to improve education and maximise patient compliance during the preparatory period will enhance the efficacy of bowel preparation.
The study compares the efficacy of bowel preparation between the face-to-face re-education (FFRE group) and telephone re-education (TRE group) in patients.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| telephone re-education(TRE) | Active Comparator | Subjects who are randomized into this group receive regular instructions at the time of their appointment to discuss colonoscopy (a nurse provides education of 5 minutes and meanwhilet sent a bookle to the patient) and a TRE which was conducted by a investigator at 15:00-17:00 on the day before colonoscopy. |
|
| face-to-face re-education (FFRE) | Experimental | Subjects who are randomized into this group receive regular instructions on the day of their appointment to discuss colonoscopy and also a FFRE which was conducted by a investigator on the same-day of procedure at hospital. |

|---|---|---|---|---|
| telephone re-education(TRE) | Behavioral | Subjects who are randomized into this group receive regular instructions at the time of their appointment to discuss colonoscopy (a nurse provides education of 5 minutes and meanwhilet sent a bookle to the patient) and a TRE which was conducted by one investigator at 15:00-17:00 on the day before colonoscopy. |
| Measure | Description | Time Frame |
|---|---|---|
| Adequate bowel preparation quality at the time of colonoscopy defined by Boston Bowel Preparation Scale rating scores≥6 among 2 groups. | This is an established rating scale to evaluate the quality of bowel prep. The ratings will be compared among the 2 groups. | 5 months |
| Measure | Description | Time Frame |
|---|---|---|
| Rate of compliance with instructions among 2 groups | Compliance was scored on a 3-grade scale based on the intake of bowel solution: 0 = optimal (intake of 100% of the solution); 1 = good (intake of ≥75% of the solution); 2 = poor (intake of <75% of the solution). | 5 months |
| Measure | Description | Time Frame |
|---|---|---|
| Willingness to repeat bowel preparation among 2 groups. | The willingness to repeat the same bowel preparation,a patient's subjective evaluation of the bowel preparation was recorded by a questionnaire | 5 months |
| Polyp detection rate among 2 groups. |
