Investigation and analysis on the status of heart sound auscultation and training needs of medical students
Abstract
Objective To clarify the current direction of improvement of heart sound auscultation teaching. Methods Questionnaire survey was conducted on the students of Peking Union Medical College who had studied diagnostics. At the same time, two tests of heart sound auscultation for medical students were collected. Two teams of residents were interviewed to investigate the mastery of medical students in heart sound auscultation and learning problems. Results Forty-seven students answered the questionnaire. A total of 177 test scores in the diagnostic heart sound section of the medical students of two grades were collected. Ten residents from the two interview teams participated in the interview. There are 87.2% of students think sound auscultation is very important in the clinical. The teaching of diagnostics for heart sounds is mainly explained by the teacher by demonstration of heart sound recordings and language descriptions, but only 53.2% of students learn some of the content and, 4.3% students said that they did not learn at all. There are 44% of the students who are able to answer correctly in the heart sound case examina- tions,nearly 80% of medical students and residents were not confident in understanding heart sounds. About 76.6% of students would look for special heart sound teaching software and audio for further study, but only 6.4% of students thought that such teaching materials and software were of great help, mainly due to the distortion of heart sounds provided by auxiliary teaching materials. Medical students hope that teachers provide effective heart sound software, real heart sound databases, and a large number of cases supplemented with medical history and imaging examination results to support their clinical reasoning; medical students also hope to obtain more bedside auscultation opportunities. Conclusions The article presented here showed shortcomings of the existing heart sound teaching, and provide some evidence from learners' side to improve learning outcomes.
