便携式超声联合CBL在血管外科教学查房中的应用

The Application of Portable Ultrasound Combined With Case-based Learning in Vascular Surgery Teaching Rounds

目的为探索更佳的血管外科临床教学模式,本研究尝试将便携式超声(portable ultrasound,PUS)联合以案例为基础的教学法(case-based learning,CBL)应用于住院医师教学查房,研究二者结合后的教学效果。方法2017年9月—2019年8月,共54名住培医师随机分为两组,分别采用PUS+CBL及单纯CBL的教学方式,比较住培结束后两组的理论水平、临床能力及教学的满意度。结果住培结束后,两组理论测试结果差异无统计学意义(P>0.05),临床测试结果显示CBL+PUS组明显高于单纯CBL组;在满意度调查中学习兴趣、自学能力、临床思维能力、学习效果、满意度方面,CBL+PUS组明显高于单纯CBL组,两组差异有统计学意义(P<0.05)。结论PUS联合CBL的教学法可提升教学效率,提高住院医师的临床能力。

Objective To explore a better clinical teaching model of vascular surgery,the study attempted to apply portable ultrasound(PUS)and case-based learning(CBL)to the teaching rounds of resident physicians,and studied the teaching effect of the combination of two models.Methods From September 2017 to August 2019,a total of 54 medic doctors were randomly divided into two groups,using the teaching method of PUS+CBL and CBL alone,respectively,to compare the theoretical level,clinical ability and teaching satisfaction of the two groups after the end of program.Results There was no statistically significant in the theoretical test results between the two groups after the end of the program(P>0.05).The clinical test results showed that the CBL+PUS group was significantly higher than the CBL group.In terms of learning interest,selflearning ability,clinical thinking ability,learning effect and satisfaction in the satisfaction survey,the CBL+PUS group was significantly higher than the CBL group,and there was a statistically statistical difference between the two groups(P<0.05).Conclusion The teaching method of PUS combined with CBL can improve the teaching efficiency and the clinical ability of residents.
