Electronic sources of medical information are plentiful, and numerous studies have demonstrated the use of the Internet by patients and the variable reliability of these sources. Studies have investigated neither the use of web-based resources by residents, nor the reliability of the information available on these websites.
A web-based survey was distributed to surgical residents in Michigan and third- and fourth-year medical students at an American allopathic and osteopathic medical school and a Caribbean allopathic school regarding their preferred sources of medical information in various situations. A set of 254 queries simulating those faced by medical trainees on rounds, on a written examination, or during patient care was developed. The top 5 electronic resources cited by the trainees were evaluated for their ability to answer these questions accurately, using standard textbooks as the point of reference.
The respondents reported a wide variety of overall preferred resources. Most of the 73 responding medical trainees favored textbooks or board review books for prolonged studying, but electronic resources are frequently used for quick studying, clinical decision-making questions, and medication queries. The most commonly used electronic resources were UpToDate, Google, Medscape, Wikipedia, and Epocrates. UpToDate and Epocrates had the highest percentage of correct answers (47%) and Wikipedia had the lowest (26%). Epocrates also had the highest percentage of wrong answers (30%), whereas Google had the lowest percentage (18%). All resources had a significant number of questions that they were unable to answer.
Though hardcopy books have not been completely replaced by electronic resources, more than half of medical students and nearly half of residents prefer web-based sources of information. For quick questions and studying, both groups prefer Internet sources. However, the most commonly used electronic resources fail to answer clinical queries more than half of the time and have an alarmingly high rate of inaccurate information.
医学信息的电子来源丰富多样，众多研究已表明患者对互联网的使用情况以及这些来源的可靠性参差不齐。然而，尚无研究调查住院医师对基于网络资源的使用情况，也未探究这些网站上信息的可靠性。
针对密歇根州的外科住院医师以及美国一所全科和骨科医学院及一所加勒比地区全科医学院的三、四年级医学生，开展了一项基于网络的调查，询问他们在各种情况下偏好的医学信息来源。设计了一组254个问题，模拟医学实习生在查房、笔试或患者护理过程中遇到的问题。以标准教科书为参考，对实习生提及的排名前5的电子资源准确回答这些问题的能力进行评估。
受访者报告了各种各样总体偏好的资源。73名参与调查的医学实习生中，大多数人在长时间学习时更喜欢教科书或复习资料，但电子资源常用于快速学习、临床决策问题和药物查询。最常用的电子资源是UpToDate、谷歌、Medscape、维基百科和Epocrates。UpToDate和Epocrates的正确答案比例最高（47%），维基百科的比例最低（26%）。Epocrates的错误答案比例也最高（30%），而谷歌的比例最低（18%）。所有资源都有大量无法回答的问题。
尽管纸质书籍尚未完全被电子资源取代，但超过一半的医学生和近一半的住院医师更喜欢基于网络的信息来源。对于快速提问和学习，两组都更喜欢互联网资源。然而，最常用的电子资源在一半以上的时间里无法回答临床问题，且不准确信息的比例高得惊人。
