Inadequate bowel preparation rates should be considered before screening colonoscopy is recommended

Rex et al1 provided a comprehensive update of the U.S. Multi-Society Task Force of Colorectal Cancer recommendations on colon cancer screening. They cite good evidence in support of a sequential approach based on colonoscopy, first based on sensitivity and cost effectiveness. The authors also discuss tools for patients (and primary care physicians) to judge whether colonoscopy is performed at a high level. These include asking about adenoma detection rate, cecal intubation rate, and use of split-dosing bowel preparation.
