About this study

The investigators compare video education plus standard education versus standard education for bowel preparation before a colonoscopy and include a number of languages including English, Spanish, Russian, Haitian Creole, and Urdu. The educational content also includes psychological content based upon the Theory of Planned Behavior. The primary outcome will be the quality of bowel preparation, as measured by the Boston Bowel Preparation Scale (BBPS) score,

Primary outcomes

  1. Boston Bowel Preparation Scale (continuous)

    Time frame: Perioperative/Periprocedural

    Quality of bowel preparation measured by the Boston Bowel Preparation Scale. Scores range from 0 through 3. Higher scores indicate a better outcome..

Secondary outcomes

  1. Boston Bowel Preparation Scale (categorical)

    Time frame: Perioperative/Periprocedural

    Boston Bowel Preparation Scale adequacy of preparation score ≥ 2 in all regions.

    Quality measured by the Boston Bowel Preparation Scale. Scores range from 0 through 3. Higher scores indicate a better outcome..

  2. Polyp detection rate proportion

    Time frame: Perioperative/Periprocedural

    Proportion of individuals undergoing a colonoscopy in whom at least one polyp is detected. Values range from 0 through 1. Higher values indicate a better outcome.

  3. Adenoma detection rate proportion

    Time frame: Perioperative/Periprocedural

    Proportion of individuals undergoing a colonoscopy in whom at least one adenomatous polyp is found. Values range from 0 through 1. Higher values indicate a better outcome.

  4. Cecal intubation rate proportion

    Time frame: Perioperative/Periprocedural

    Proportion of colonoscopies in which the endoscope successfully reaches the caecum. Values range from 0 through 1. Higher values indicate a better outcome.

  5. Withdrawal time

    Time frame: Perioperative/Periprocedural

    Duration in minutes taken to withdraw the colonoscope from the caecum to the rectum. Values range from 1 through 60. Higher values indicate a worse outcome.

  6. Adherence to bowel preparation instructions

    Time frame: Perioperative/Periprocedural

    Following what was told to do by bowel preparation instructions. Total of 7 original questions scored as no for 0 or yes for 1 with a total score ranging from 0 through 7. Higher values indicate a better outcome.

  7. Amsterdam Preoperative Anxiety and Information Scale

    Time frame: baseline

    Self-assessed at baseline using the Amsterdam Preoperative Anxiety and Information Scale (APAIS). Scores range from 6 through 30. Higher scores greater anxiety.

  8. Overall experience with the bowel preparation process

    Time frame: Perioperative/Periprocedural

    Self-report about experience with the bowel preparation process. One original question with 5 choices of very unpleasant, unpleasant , neutral , pleasant , very pleasant . There is no score. The best answer would be "very pleasant."

  9. Desire to undergo future colonoscopies if indicated

    Time frame: Perioperative/Periprocedural

    Self-report about having another colonoscopy. One original question with 5 choices of strongly disagree, disagree, neutral, agree , strongly agree. The best answer would be "strongly agree."
