Arm && Interventions

Group	Intervention	Description
Educational telephone intervention	Educational telephone intervention	This group will receive a nurse-led educational telephone intervention for bowel preparation 24-48 before the colonoscopy
Standard education for colonoscopy	Standard education for colonoscopy	The control group will receive standard education for bowel preparation at the time of colonoscopy scheduling

Primary Outcome Measures

Name	Time	Method
Adequate bowel cleansing for colonoscopy	At the moment of colonoscopy	The efficacy of bowel preparation will be rated by blinded endoscopists using the Boston Bowel Preparation Scale (BBPS). Adequate bowel cleansing will be defined as a BBPS of 2 or more points in every segment of the colon and inadequate bowel cleansing will be defined by at least one of the colon segments with less than 2 points.

Secondary Outcome Measures

Name	Time	Method
Adenoma detection rate in the right colon	At the moment of colonoscopy	Ratio of patients with at least one adenoma in the right colon (proximal to the splenic flexure)
Overall serrated lesion detection rate	At the moment of colonoscopy	Ratio of patients with at least one serrated lesion in the overall colon
Serrated lesion detection rate in the right colon	At the moment of colonoscopy	Ratio of patients with at least one serrated lesion in the right colon (proximal to the splenic flexure)
Boston Bowel Preparation Scale	At the moment of colonoscopy	Application of the Boston Bowel Preparation Scale to evaluate colonoscopy bowel cleansing
Barcelona Bowel Preparation Scale	At the momento of colonoscopy	Application of the Barcelona Bowel Preparation Scale to evaluate colonoscopy bowel cleansing
Overall adenoma detection rate, as defined by the ratio of patients with at least one adenoma in the overall colon	At the moment of colonoscopy	The ratio of patients with at least one adenoma in the overall colon
Complete colonoscopy rate	At the moment of colonoscopy	Ratio of successful complete colonoscopies (cecal intubation or in case of previous surgery, ileocolic anastomosis)
