Wikipedia is a multilingual, open content online encyclopedia that exists as a wiki. It is written collaboratively by people with varying degrees of expertise. Indeed, anyone who can access Wikipedia's website may alter any of its content. Wikipedia contains a significant number of articles on health-related topics, but the accuracy and completeness of this information is intuitively circumspect since experts and non-experts alike may contribute to the site's content. Thus, the intent of my research was to systematically evaluate the accuracy and completeness of the sample of health-related articles in Wikipedia.
