Several educators have reported poor identification of abnormal cardiac sounds by primary care residents. Practice and review with cardiology patient simulators and prerecorded heart sounds has been shown to increase the accuracy of diagnosis by medical students and residents.
The participants were 15 members of an urban family practice residency. The residents were presented with simulated heart sounds and were asked to identify them in a pretest and posttest. Between the tests, participants were invited to three separate teaching sessions that involved a discussion of cardiac auscultatory findings and a review of audiotaped similar heart sounds. Residents who were unable to attend the teaching sessions formed a control group.
The pretest identification rate was 36% for the heart sounds. This improved to 62% for all residents after the intervention. Higher rates of improvement were demonstrated by the residents who attended one or more teaching sessions, compared with the residents who attended no teaching sessions.
Small-group discussion and repetitive auscultation of simulated heart sounds can improve the cardiac auscultatory proficiency of family practice residents.
多位教育工作者报告称,基层医疗住院医师对异常心音的识别能力较差。事实证明,使用心脏病患者模拟器和预先录制的心音进行练习和复习,可提高医学生和住院医师的诊断准确性。
参与者为15名城市家庭医学住院医师。向住院医师展示模拟心音,并要求他们在预测试和后测试中进行识别。在两次测试之间,参与者被邀请参加三场不同的教学课程,内容包括对心脏听诊结果的讨论以及对类似心音录音的复习。无法参加教学课程的住院医师组成一个对照组。
心音的预测试识别率为36%。干预后,所有住院医师的识别率提高到了62%。与未参加任何教学课程的住院医师相比,参加了一场或多场教学课程的住院医师的提高率更高。
小组讨论和对模拟心音的反复听诊可提高家庭医学住院医师的心脏听诊水平。
