The objective of this study was to determine if a training module improves the auscultation skills of medical students at the University of Maryland School of Medicine. Second-year medical students completed pretests on 12 heart sounds followed by a 45-minute training module on clinical auscultation, with retesting immediately after the intervention and during their third-year pediatrics clerkship. The control group consisted of third-year medical students who did not have the intervention. There was a 23% improvement in the identification of heart sounds postintervention (P < .001). Diastolic and valvular murmurs were poorly identified pre- and post intervention. There was a 6% decline in accuracy of the intervention group in the following academic year. The intervention group was superior to the control group at identifying the tested heart sounds (49% vs 43%, P = .04). The accuracy of second-year medical students in identifying heart sounds improved after a brief training module.
本研究的目的是确定一个培训模块是否能提高马里兰大学医学院医学生的听诊技能。二年级医学生先对12种心音进行了预测试,随后接受了45分钟的临床听诊培训模块,在干预后立即进行重新测试,并在三年级儿科实习期间再次测试。对照组由未接受该干预的三年级医学生组成。干预后心音识别能力提高了23%(P <.001)。干预前后舒张期和瓣膜杂音的识别情况都很差。在下一学年,干预组的准确率下降了6%。在识别测试的心音方面,干预组优于对照组(49%对43%,P = 0.04)。经过一个简短的培训模块后,二年级医学生识别心音的准确率有所提高。
