Colorectal cancer (CRC) is a leading cause of cancer death in the US and high-quality colonoscopy is key to efficient CRC screening and detection. Previous studies indicated that 18% to 31% of patients have inadequate bowel preparation. It has been reported that nearly 20% of patients with poor bowel preparation fail to follow instructions. We hypothesized that educating physicians who order colon purgatives with general tips on good quality bowel cleansing will improve the adequacy of preparation by helping to choose the most appropriate protocol tailored to each patients’ medical comorbidities.
