Overview Colorectal Cancer Bowel Preparation Regimens Survey 2

Colorectal Cancer Third most common cancer Second leading cause of cancer-related deaths Screening colonoscopy has been shown to reduce mortality ▫U.S Preventive Services Task Force recommends Colorectal Cancer Screening for those aged 50 years and above with average risk USPSTF

Adequacy of Colonoscopy Depends on Prep 4

Adequacy of Colonoscopy Up to 25% of patients undergoing colonoscopy have poor bowel preparation ▫Lowers the detection of small polyps (<9mm) ▫Increased risk of procedural complications ▫Decreased completion rates ▫Increases the time the endoscopist takes to try to suction and clean the colon Van Dongen

Different Dosing Regimens Split-Dose Traditional Same Day Time of day 7

Split-Dose Superior to full-dose PEG with respect to ▫Colon Cleansing ▫Patient compliance ▫Patient’s willingness to repeat the same bowel preparation ▫Nausea Kilgore et al

Survey of Local CRF Programs in Maryland 13 questions aimed to identify practice habits of endoscopists involved in the program Program managers in each county of Maryland who work directly with endoscopists through the statewide Cigarette Restitution Fund Colorectal Cancer Screening Program 9

Conclusions Physicians are implementing split dose regimens into their practice. Physicians are using different bowel preps for different patients, suggesting they are taking into account the patients past medical history and ability to complete the various regimens. 16

Conclusion The literature suggests that split-dose regimens: ▫Improve quality of the study ▫Reduce cost and complications ▫Are more favorable to the patient 17

Information for the screening programs: Please encourage your providers to use split- dosing regimens if not using split dose currently Please disseminate our “Information to the Provider” handout to the endoscopists in your program 18
