PURPOSE: Patients often request to undergo computed tomographic colonography (CTC) from radiologists or referring physicians on the basis of their personal examination of information on the Web. Therefore, the authors examined the information on CTC and virtual colonoscopy available for consumers on the Web to assess its quality.
MATERIALS AND METHODS: The term virtual colonoscopy was entered into 3 popular search engines: Google, Yahoo, and MSN. In each case, evaluation was limited to the first 50 Web sites, or hits, which were recorded and analyzed for content, comprehensiveness, and accuracy.
RESULTS: Sixty-seven Web sites were deemed appropriate for further analysis. More than half of the sites reported currency dates more than 2 years old. Only a third of the sites included information about the risk factors for colorectal cancer. About a third of the sites did not explain the indications for the use of CTC, and the remaining sites lacked consistent descriptions of the indications. Few Web sites offered or described the option of performing same-day optical colonoscopy for patients with abnormal results on CTC.
CONCLUSION: The data suggest that patients are often armed with very incomplete information from Web sites on CTC. Web sites were often found to be outdated, to contain conflicting information, and were lacking descriptions of patient risk factors for colorectal cancer. Several suggestions are made to improve the dissemination of comprehensive, current, and accurate information.
