The EPAGE internet guideline as a decision support tool for determining the appropriateness of colonoscopy.

Background: Few studies have examined how physicians perceive guidelines, much less their perceptions of an Internet presentation of such guidelines. This study assessed physicians' acceptance ofan Internet-based guideline on the appropriateness of colonoscopy.

Methods: Gastroenterologists participating in an international observational study consulted an Internet-based guideline for consecutive patients referred for colonoscopy. The guideline was produced by the European Panel on the Appropriateness of Gastrointestinal Endoscopy (EPAGE), using a validated method (RAND). Through the use of questionnaires, physicians were asked their opinions and perspectives of the guideline and website.

Results: There were 289 patients included in the study. The mean time for consulting the website was 1.8 min, and it was considered easy to use by 86% of physicians. The recommendations were easily located for 82% of patients and physicians agreed with the appropriateness in 86% of cases. According to the EPAGE criteria, colonoscopy was appropriate, uncertain, and inappropriate in 59, 28, and 13% of patients, respectively.

Conclusions: The EPAGE guideline was considered acceptable and user-friendly and the use, usefulness and relevance of the website were considered acceptable. However, its actual use will depend on the removal of certain organizational and cultural obstacles.
