Summary
Brief summary (as posted)
Colorectal cancer (CRC) is a common and life threatening condition that will affect one in thirteen individuals. Colonoscopy is the most commonly used procedure to identify colorectal malignancies or precancerous lesions at an earlier stage, which affords an opportunity for cure. However, low level of bowel cleanliness hinders polyp detection and therefore can limit colonoscopy effectiveness. Historically, the majority of the studies have focused on pharmacological factors to optimize bowel preparation quality. Recently, non-pharmacological factors have been found to have significant increases in bowel preparation quality. The purpose of this study is to evaluate the effectiveness of web-based instructions vs. the historical phone/letter instructions given to patients planning to have a colonoscopy.
