Quality of bowel preparation can affect the completeness and duration of colonoscopy, detection of neoplastic lesions, and the safety of polypectomy. The ASGE and ACG Task Force for quality improvement during colonoscopy have proposed a performance target of >85% of colonoscopies for which adequate preparation is achieved. However there remain challenges in achieving this metric, as several factors including patient health literacy, socioeconomic status, language barriers, and complicated instruction tools can influence the quality of bowel preparation.
