Inpatient colonoscopy bowel preparation is frequently inadequate, negatively impacting patient safety and procedure quality, directly leading to higher costs due to prolonged hospital stays. At the University of Chicago Medical Center (UCMC), inpatient bowel preparation ordering had not previously been standardized, which led to practice variability and suboptimal results. Split-dose inpatient colonoscopy preparation has previously been shown to improve the quality of colonoscopy preparation. Thus, our aim was to introduce an automated split-dose bowel preparation order set in order to improve the quality of inpatient bowel preparation.
