About: Grading Methodology

The Library’s evidence grading methodology is based on the 2011 version of the Oxford Centre for Evidence-based Medicine (CEBM) – Levels of Evidence and the U.S. Preventive Services Task Force (USPSTF) I-Scores. Recommendations chosen from professional society guidelines, local best practices and peer-reviewed literature are converted into Health-IT consumable clinical logic and then graded by three independent parties – two curators and a validating clinician. Once agreement on a final grade is reached, the full record will be made freely available to the public. A more detailed view of the grading methodology can be found under the Training Materials page.
