随着Web 2.0技术的出现，维基百科等用户编辑的在线资源越来越多地被用来获取信息。目的：比较维基百科与Medscape Drug Reference [MDR]数据库中药物信息的范围、完整性和准确性。方法：对维基百科和MDR的8类药物信息进行评价。构建问题，并使用权威资源验证答案。维基百科和MDR根据范围（覆盖范围）和完整性进行评估。准确性由事实错误和遗漏错误来跟踪。使用描述性统计量总结组分。Fisher精确检验用于比较范围，配对Student t检验用于比较Wikipedia中的当前结果与当前访问前90天的条目。结果：与MDR（82.5%; P <0.001）相比，Wikipedia能够回答的药物信息问题（40.0%）明显较少。维基百科在给药信息方面表现不佳，评分为0%，而MDR评分为90.0%。在维基百科中找到的答案有76.0%是完整的，而MDR提供的答案有95.5%是完整的;总体而言，维基百科的答案比Medscape中的答案更不完整（p
With the advent of Web 2.0 technologies, user-edited online resources such as Wikipedia are increasingly tapped for information. However, there is little research on the quality of healthy information found in Wikipedia.OBJECTIVE: To compare the scope, completeness, and accuracy of drug information in Wikipedia with that of a free, online, traditionally edited database (Medscape Drug Reference [MDR]).METHODS: Wikipedia and MDR were assessed on 8 categories of drug information. Questions were constructed and answers were verified with authoritative resources . Wikipedia and MDR were evaluated according to scope (breadth of coverage) and completeness. Accuracy was tracked by factual errors and errors of omission. Descriptive statistics were used to summarize the components. Fisher's exact test was used to compare scope and paired Student's t-test was used to compare current results in Wikipedia with entries 90 days prior to the current access.RESULTS: Wikipedia was able to answer significantly fewer drug information questions (40.0%) compared with MDR (82.5%; P < 0.001). Wikipedia performed poorly regarding information on dosing, with a score of 0% versus the MDR score of 90.0%. Answers found in Wikipedia were 76.0% complete, while MDR provided answers that were 95.5% complete; overall, Wikipedia answers were less complete than those in Medscape (p
