BACKGROUND
The present study compares the value of additional use of computer simulated heart sounds, to conventional bedside auscultation training, on the cardiac auscultation skills of 3rd year medical students at Oslo University Medical School.
METHODS
In addition to their usual curriculum courses, groups of seven students each were randomized to receive four hours of additional auscultation training either employing a computer simulator system or adding on more conventional bedside training. Cardiac auscultation skills were afterwards tested using live patients. Each student gave a written description of the auscultation findings in four selected patients, and was rewarded from 0-10 points for each patient. Differences between the two study groups were evaluated using student's t-test.
RESULTS
At the auscultation test no significant difference in mean score was found between the students who had used additional computer based sound simulation compared to additional bedside training.
CONCLUSIONS
Students at an early stage of their cardiology training demonstrated equal performance of cardiac auscultation whether they had received an additional short auscultation course based on computer simulated training, or had had additional bedside training.
背景
本研究比较了在奥斯陆大学医学院的三年级医学生中，使用计算机模拟心音与传统床旁听诊训练对心脏听诊技能的额外价值。
方法
除了常规课程外，将每组 7 名学生随机分为两组，分别接受 4 小时的额外听诊训练，一组使用计算机模拟系统，另一组增加传统的床旁训练。之后使用真实患者对心脏听诊技能进行测试。每位学生对 4 名选定患者的听诊结果进行书面描述，并对每位患者获得 0-10 分的奖励。使用学生 t 检验评估两组研究之间的差异。
结果
在听诊测试中，使用附加基于计算机的声音模拟的学生与接受附加床旁训练的学生之间的平均分数无显著差异。
结论
在心脏病学培训早期阶段，接受基于计算机模拟训练的附加短期听诊课程或接受额外床旁训练的学生，其心脏听诊表现相等。
