Bowel Preparation Clinical Trial
Official title:
Effecacy of Face-to-face Bowel Preparation for Afternoon Colonoscopy: a Randomised Clinical Trial
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.
