The efficacy of bedside information products has not been properly evaluated, particularly in developing countries.
To compare four evidence-based textbooks by comparing efficacy of their use by clinical residents, as measured by the proportion of questions for which relevant answers could be obtained within 20 min, the time to reach the answer and user satisfaction.
One hundred and twelve residents were taught information mastery basics and were randomly allocated to four groups to use: (1) ACP PIER, (2) Essential Evidence Plus (formerly InfoRetriever), (3) First Consult, and (4) UpToDate. Participants received 3 of 24 questions randomly to retrieve the answers from the assigned textbook. Retrieved answers and time-to-answers were recorded by special designed software, and the researchers determined if each recorded answer was relevant.
The rate of answer retrieval was 86% in UpToDate, 69% in First Consult, 49% in ACP PIER, and 45% in Essential Evidence Plus (p < 0.001). The mean time-to-answer was 14.6 min using UpToDate, 15.9 min using First Consult, 16.3 min using Essential Evidence Plus, and 17.3 min using ACP PIER (p < 0.001).
UpToDate seems more comprehensive in content and also faster than the other three evidence-based textbooks. Thus, it may be considered as one of the best sources for answering clinicians' questions at the point of care.
床边信息产品的疗效尚未得到适当评估，尤其是在发展中国家。
通过比较临床住院医师使用四种基于证据的教科书的效果，来比较它们的疗效，以在 20 分钟内获得相关答案的问题比例、获得答案的时间和用户满意度来衡量。
112 名住院医师接受了信息掌握基础知识的培训，并随机分为四组使用：（1）ACP PIER，（2）Essential Evidence Plus（前身为 InfoRetriever），（3）First Consult，和（4）UpToDate。参与者随机收到 3 个 24 个问题中的问题，从指定的教科书中检索答案。答案和答案时间由专门设计的软件记录，研究人员确定每个记录的答案是否相关。
UpToDate 的答案检索率为 86%，First Consult 为 69%，ACP PIER 为 49%，Essential Evidence Plus 为 45%（p<0.001）。使用 UpToDate 的平均回答时间为 14.6 分钟，使用 First Consult 的平均回答时间为 15.9 分钟，使用 Essential Evidence Plus 的平均回答时间为 16.3 分钟，使用 ACP PIER 的平均回答时间为 17.3 分钟（p<0.001）。
UpToDate 在内容上似乎更全面，也比其他三种基于证据的教科书更快。因此，它可以被认为是在护理点回答临床医生问题的最佳来源之一。
