  Purpose

The investigators goal is to improve bowel preparations with an educational video on the Center for Digestive Disorders (CDD) website that explains the steps required for bowel preparation for those patients undergoing screening colonoscopies. The video will focus on explaining the purpose of a screening colonoscopy, the rationale for bowel preparation, the pre-colonoscopy diet, and the instructions for completing the laxative. In a randomized fashion, patients in the control group will receive the standard written bowel preparation instructions, while patients in the intervention group will receive standard written instructions plus a link to watch the instructional video. The investigators hypothesize that an educational tool that provides visual examples of a good and poor preparation, examples of the pre-colonoscopy diet, and an explanation of how to administer the laxative will lead to improved patient compliance and a better bowel preparation. In addition, the investigators hypothesize that a better quality bowel preparation will improve detection of colonic polyps and fewer recommendations for repeat colonoscopy based solely on inadequate bowel preparation.

Primary Outcome Measures:
  • Quality of bowel preparation [ Time Frame: Day of colonoscopy only ] [ Designated as safety issue: No ]
    The primary outcome will be the endoscopist's assessment of the quality of preparation using a standardized bowel preparation scale


Secondary Outcome Measures:
  • Histology of polyp [ Time Frame: one week after colonoscopy ] [ Designated as safety issue: No ]
    number of adenomatous polyps

  • Colonoscope insertion and withdrawal times [ Time Frame: Day of colonoscopy only ] [ Designated as safety issue: No ]
    time from insertion to cecum and time from cecum to anus

  • Patient compliance [ Time Frame: Day of colonoscopy only ] [ Designated as safety issue: No ]
    Patient compliance with preparation instructions self-reported in a pre-procedure questionnaire

  • Preparation associated side effects [ Time Frame: Day of colonoscopy only ] [ Designated as safety issue: No ]
    Presence and severity of preparation associated side effects including: blaoting, abdominal pain, and nausea/vomiting

  • Patient satisfaction [ Time Frame: Day of colonoscopy only ] [ Designated as safety issue: No ]
    patient's perception of the helpfulness of the video as self-reported on a pre-procedure questionnaire.

  • Number of repeat colonoscopies due to inadequate bowel preparation [ Time Frame: Day of colonoscopy only ] [ Designated as safety issue: No ]
    Blinded endoscopist's assesment about the need for a repeat colonoscopy due to inadequate bowel preparation
