Written Recommendation to Improve Adherence in Poor Bowel Preparation

"Patients in the intervention group will receive a report of the colonoscopy that will include a written recommendation that the colonoscopy should be repeated within1 year.~The colonoscopy report will included that an adequate intestinal cleansing has not been achieved and therefore it is an invalid exploration. Additionally, a written recommendation indicating that the colonoscopy should be repeated within1 year will be included in the colonoscopy report. This recommendation is addressed both to the clinician who requested the colonoscopy and to the patient himself."
