Abstract
PURPOSE
Many patients rely on the Internet for medical information. In Korea, there are many websites providing medical information, but the quality of these websites relating to colorectal cancer remains to be clarified. This study was performed to evaluate the quality of websites providing information on colorectal cancer.
METHODS
Firstly, sites were identified using four major domestic search engines and were classified according to the administrator. Then, two surgical oncologists used the 'DISCERN' instrument to assess 12 sites (including 2 foreign sites) for the reliability and the quality of the information on treatment choice.
RESULTS
Total 297 sites were identified using the search term 'colorectal cancer'. Excluding dead links or duplicated sites, 148 sites were identified. When the sites had been classified according to the administrator of the websites, 115 (77.7%) were identified as local clinic or hospital sites, 8 (5.4%) as medical school sites, 7 (4.7%) as institute or public health sites, 11 (7.4%) as commercial sites, and 7 (4.7%) as private sites. The results of the evaluations by the two examiners showed moderate inter-examiner reliability (K=0.41). The evaluations of the domestic sites by using DISCERN showed serious or important shortcomings in the quality of information on treatment choices and in reliability. Among these domestic websites, the quality of information provided at private or local hospital sites was poorer than that provided at institute or public health sites.
CONCLUSIONS
About 80% of the websites providing medical information on colorectal cancer were identified as private or local hospital sites. Evaluations of the information provided at domestic sites showed serious or important shortcomings.
