Objectives
To explore medical students' use of computer tutorials embedded in a busy clinical setting; to demonstrate that such tutorials can increase knowledge gain over and above that attributable to the clinical rotation itself.
Methods
Six tutorials were installed on a computer placed in a central area in an emergency department. Each tutorial was made up of between 33 and 85 screens of information that include text, graphics, animations, and questions. They were designed to be brief (10 minutes), focused, interactive, and immediately relevant. The authors evaluated the intervention using quantitative research methods, including usage tracking, surveys of faculty and students, and a randomized pretest-posttest study.
Results
Over 46 weeks, 95 medical students used the tutorials 544 times, for an overall average of 1.7 times a day. The median time spent on completed tutorials was 11 minutes (average [SD], 14 [±12] minutes). Seventy-four students completed the randomized study. They completed 65% of the assigned tutorials, resulting in improved examination scores compared with the control (effect size, 0.39; 95% confidence interval = 0.15 to 0.62). Students were positively disposed to the tutorials, ranking them as "valuable." Fifty-four percent preferred the tutorials to small group teaching sessions with a preceptor. The faculty was also positive about the tutorials, although they did not appear to integrate the tutorials directly into their teaching.
Conclusions
Medical students on rotation in a busy clinical setting can and will use appropriately presented computer tutorials. The tutorials are effective in raising examination scores. 相似文献

疾病的正确诊断和合理治疗是患者和医务工作者共同的心愿。在广东省人民医院肿瘤中心,吴一龙教授指导临床医生应用循证医学理论进行肿瘤的多学科综合治疗,开展临床病例讨论。讨论会上各学科共同围绕一个病例或一个病种进行会诊,临床、病理、B超、放射影像等资料齐全。除相关科室提前准备的中心性发言外,到会人员各抒己见,气氛热烈。参会人员受益匪浅,提高了对疑难病例的诊治水平。为了将他们的诊治经验传播出去,让更多的临床医生获益,我刊开辟“循证病例讨论”栏目,希望广大医务工作者关注此栏目。[编者按] 相似文献

高等医学院校医学化学教材改革的几点思考 总被引:2,自引:1,他引:1
医学的发展已进入分子水平,医学生必须具有扎实的化学基础才能适应专业学习及临床、科研工作的需要。现行医学化学教材大多沿用几十年前的模式,部分内容陈旧滞后,实用性不强。面对现实,改革势在必行。我们认为,突出重点、注重实用、体现医学特色应作为改革的方向。 相似文献
