A survey assessing knowledge about colorectal cancer incidence and prognosis as well as willingness to undergo screening with various tests (e.g., optical colonoscopy, stool-based tests, CT colonography) was administered to consecutive patients of a general academic-based internal medicine clinic. Survey response rate was 86.3%. A majority of respondents (55%) reported being aware of general information about colorectal cancer, and 99% indicated a belief that colorectal cancer screening was a good idea. A majority of respondents (73%) were willing to undergo optical colonoscopy, and some were willing to undergo stool-based tests (48%) or CT colonography (40%). A majority reported being more willing to undergo a colorectal cancer screening test if the test did not involve radiation (86%), did not involve insertion of a tube or device into the rectum (78%), did not involve a pre-procedural bowel cleansing regimen (73%), or did not involve sedation (60%). In conclusion, improved patient education about the negligible radiation risk associated with CT colonography and/or development of a non-invasive imaging test that did not involve a pre-procedural bowel cleansing regimen may increase rates of colorectal cancer screening.
