OBJECTIVE
To describe a Web-based guideline tutorial system and evaluate its features.
METHODS
A Web-based tutorial system called SAGE (Self-study Acceleration with Graphic Evidence) was constructed to teach knowledge important for care after myocardial infarction. SAGE features a pretest, followed by an overview that coordinates studying resources for a set of learning objectives. Resources include pretest answers, guideline passages, and graphical presentations of clinical trial results. Data on the use of SAGE was obtained from 79 residents participating in a larger trial. Linear regression was used to correlate the amount learned with resource-use, and resource-use with user characteristics.
RESULTS
On average, users accessed less than half of the guideline passages and very little of the graphic evidence. Greater use of guideline passages was correlated with greater immediate learning, but use of graphic evidence was not.
CONCLUSIONS
Further research is needed to motivate more thorough self-study and to integrate clinical trial evidence with guideline-based education.
目的
描述一个基于网络的指南教程系统并评估其特点。
方法
构建了一个名为SAGE（基于图形证据的自学加速）的基于网络的教程系统，用于教授心肌梗死后护理的重要知识。SAGE的特点是有一个预测试，随后是一个概述，该概述为一组学习目标协调学习资源。资源包括预测试答案、指南段落和临床试验结果的图形展示。关于SAGE使用情况的数据来自参与一项更大规模试验的79名住院医师。使用线性回归来关联所学知识量与资源使用情况，以及资源使用情况与用户特征。
结果
平均而言，用户访问的指南段落不到一半，图形证据访问得很少。更多地使用指南段落与即时学习的增加相关，但图形证据的使用并非如此。
结论
需要进一步研究以促进更全面的自学，并将临床试验证据与基于指南的教育相结合。
