Cardiac auscultation is suffering from a declining interest caused by competing diagnostic technology and, possibly, inadequate teaching and testing of physicians-in-training. Because access to technology, traditional teaching practices, and methods of trainees' assessment vary among different countries, we speculated that trainees' proficiency in auscultation might also vary.
We tested the cardiac auscultatory skills of 314 internal medicine residents (189 from the United States, 89 from Canada, and 36 from England) from 14 programs. All participants were asked to listen by stethophones to 12 prerecorded cardiac events and to answer a multiple-choice questionnaire. They also completed a survey concerning attitudes toward cardiac auscultation and auscultatory teaching received during training.
Mean (+/- SD) identification scores for the 12 cardiac events ranged from 0% to 58% for American trainees (mean 22% +/- 12%), 0% to 58% for Canadians (mean 26% +/- 13%), and 0% to 42% for British trainees (mean 20% +/- 12%). Canadians' cumulative scores were slightly but significantly greater than those of American (P = 0.02) and British house officers (P = 0.05). British house officers improved the most during the 3 years of training (P < 0.05). Canadian and British trainees had received more auscultatory teaching during medical school and residency; they had also used audiotapes more frequently (all P < 0.001).
Auscultatory proficiency was poor in all three countries. Although there were slight differences among countries, the most striking finding was the consistent inaccuracy of all trainees. This suggests that variables other than teaching and testing affect proficiency.
由于竞争性诊断技术的出现,以及可能存在的对实习医生教学和测试不足的情况,心脏听诊的关注度正在下降。由于不同国家在获取技术、传统教学实践以及实习生评估方法等方面存在差异,我们推测实习生在听诊方面的熟练程度也可能有所不同。
我们测试了来自14个项目的314名内科住院医师(189名来自美国,89名来自加拿大,36名来自英国)的心脏听诊技能。所有参与者都被要求通过听诊器听取12个预先录制的心脏事件,并回答一份多项选择题问卷。他们还完成了一项关于对心脏听诊的态度以及在培训期间接受的听诊教学的调查。
12个心脏事件的平均(±标准差)识别分数,美国实习生为0%至58%(平均22%±12%),加拿大实习生为0%至58%(平均26%±13%),英国实习生为0%至42%(平均20%±12%)。加拿大实习生的累积分数略高于美国实习生(P = 0.02)和英国住院医生(P = 0.05),且差异具有统计学意义。英国住院医生在三年培训期间进步最大(P < 0.05)。加拿大和英国的实习生在医学院和住院医师培训期间接受了更多的听诊教学;他们也更频繁地使用录音带(所有P < 0.001)。
这三个国家的听诊熟练程度都很差。尽管国家之间存在细微差异,但最显著的发现是所有实习生的诊断结果都始终不准确。这表明除了教学和测试之外,还有其他变量会影响熟练程度。
