title: Data from: A study of how using an interactive multimedia e-book improves teachers’ ability to teach evidence-based medicine, depending on their seniority

description: Background The role of the electronic book (e-book) is a useful adjunct to
 traditional teaching methods. Our aim is to study the use of the e-book
 for teaching effects. Methods This study group was introduced to learning
 evidence-based medicine (EBM) from an interactive e-book available on the
 Internet, and a control group using a PowerPoint presentation.
 Questionnaires (21 items) assessed learners’ EBM skills before and after
 the learning. EBM learning sessions were 20–30 minutes long, followed by
 students’ feedback. Results Physicians in the study group ranked “Keyword
 filters increase the quality of the article” more highly than in the
 control group (P = 0.030). In database searching techniques, it was shown
 that “A broader discovery of useful resources” was more beneficial (P =
 0.016). In literature appraisal, it was shown that “Can I select the best
 literature I want?” was more beneficial (P = 0.002). Teaching effect,
 measured by student feedback, was better in the study group than in the
 control group for the items, “I am satisfied with this lesson,” “The
 teaching was of high quality,” “This was a good teaching method,” and “It
 aroused my interest in EBM.” There was no improvement in the teaching
 effectiveness of senior physicians with more than 10 years’ experience.
 Conclusions The use of interactive “e-books” in clinical teaching can
 enhance teachers’ EBM skills and teaching. It is clinically useful but
 varies in usefulness depending on teachers’ seniority.
description: The teachers created an answerable question using PICO model from the true
 case in the hospital and searched the electronic databases available at
 the Chang Gung Memorial Hospital (CGMH) before the study. They attempted
 to consolidate the evidence to come to a conclusion and make a
 recommendation for the question. We then gave them access to the e-book or
 PowerPoint presentation and encouraged them to practice using it. They
 re-examined the information they had written by searching, consolidating
 evidence, and correcting the recommendation. After this, the assessment
 questionnaires as in Table 2 were completed. The study group utilized the
 e-book and the control group the PowerPoint presentation without the
 e-book.
