Etude de la véracité des articles médicaux sur Wikipédia

Abstract : Introduction: The Wikipedia encyclopedia is currently one of the greatest sources of information, especially on medicine. This thesis thus raises the question: What is the veracity of the medical articles available on Wikipedia? Methods: In order to answer this question, we selected a sample of 5 items (stroke, colon cancer, diabetes mellitus, vaccination and interruption of pregnancy) which we compare, assertion by assertion, with reference sources to confirm or refute each assertion. Results: Of the 5 articles, we analyzed 868 assertions. Of this total, 82.49% were verified by the referentials, 15.55% not verifiable due to lack of information and 1.96% contradicted by the referentials. Of the contradicted results, 10 corresponded to obsolete notions and 7 to errors, but mainly dealing with epidemiological or statistical data, thus not leading to a major risk when used, not recommended, on health. Conclusion: Wikipedia is the largest extensive encyclopedic project ever created. Its open format allows everyone to create an article, to complete it or to correct it. This study of five medical articles finds a high rate of veracity with less than 2% incorrect information and more than 82% of information confirmed by scientific references. These results strongly argue that Wikipedia could be a reliable source of medical information, provided that it does not remain the only source used by people for that purpose.
