To evaluate the benefit, for medical students on their surgical rotations, of real-time educational instruction during order entry on a hospital information system.
Prospective controlled trial.
Access to educational information during computerized order entry.
Medical students in their final year at the University of Calgary.
Attainment of the surgery rotation educational objectives, as measured by performance on a multiple-choice examination.
Before they began their surgical rotations, students at two hospitals took a multiple-choice examination to measure their knowledge of surgery. One hospital had an information system with computerized order entry; students at this hospital had access, while composing orders, to educational material on the system. The other hospital did not have an information system; students there wrote orders on a paper chart. At the end of the rotation, all students took another multiple-choice examination.
Of 50 eligible students, 45 agreed to participate in the project, 21 in the treatment group and 24 in the control group. Pre-rotation scores were similar for the two groups (43 percent in the treatment group and 40 percent in the control group; SD, 10 percent). Post-rotation scores were identical for the two groups (65 percent in the treatment group and 65 percent in the control group; SD, 12 percent). A t-test analysis revealed no significant difference in performance on the examinations between the two groups.
This study did not demonstrate a learning advantage for medical students who have access to educational material on a hospital information system.
评估在医院信息系统中进行医嘱录入时实时教育指导对参加外科轮转实习的医学生的益处。
前瞻性对照试验。
在计算机化医嘱录入过程中获取教育信息。
卡尔加里大学最后一年的医学生。
通过多项选择题考试成绩衡量外科轮转实习教育目标的达成情况。
在开始外科轮转实习之前,两所医院的学生参加了一项多项选择题考试,以测试他们的外科学知识。其中一所医院拥有带有计算机化医嘱录入功能的信息系统;该医院的学生在录入医嘱时可在系统上获取教育资料。另一所医院没有信息系统;那里的学生在纸质图表上书写医嘱。轮转实习结束时,所有学生又参加了一次多项选择题考试。
在50名符合条件的学生中,45名同意参与该项目,21名在治疗组,24名在对照组。两组的轮转实习前成绩相似(治疗组为43%,对照组为40%;标准差为10%)。两组的轮转实习后成绩相同(治疗组和对照组均为65%;标准差为12%)。t检验分析显示两组考试成绩无显著差异。
本研究未证明能访问医院信息系统上教育资料的医学生具有学习优势。
