This is a multicenter interrupted-time series study. The study will include patients between the age of 18-85 year old, both males and females, who are scheduled for inpatient colonoscopy procedure. The study will be divided into two phases: The initial phase will be a prospective review of inpatient colonoscopy procedure between September, 1st 2020 and March, 31st 2021 to assess overall adequacy of inpatient colonoscopy preparation and patient satisfaction at the three participating sites using standard of care colonoscopy preparation prior to implement our intervention. The intervention phase will take place between April, 1st 2021 and October 31st 2021, where all patient undergoing inpatient colonoscopy procedures will receive Lubiprostone in addition to large-volume PEG-ELS. The patients will be evaluated with colonoscopy the next day. The preparation quality will be documented using the Boston Bowel Preparation Scale (BBPS).
