RESUMO
Objective:To investigate the effect of situational simulation combined with video feedback in cardiopulmonary and abdominal clinical probation of diagnostics.Methods:Two hundred and twenty-four clinical undergraduates from the second affiliated hospital of Guangxi Medical University were randomized into the experimental group ( n=112) and the control group ( n=112). The experimental group applied situational simulation combined with video feedback methods in the cardiopulmonary and abdominal clinical probation. In other words, according to the assignment of diseases, two students played the role of "physician and patient" and conducted corresponding consultation and physical examination, in which the positive and negative video feedback were integrated to standardize students' physical examination skills. The control group adopted conventional teaching method. The teaching effect of the two groups was evaluated through unified and standardized scores of theoretical tests, cases analysis, and clinical skills operation, and the experimental group was conducted anonymous questionnaires to 112 students. SPSS 22.0 was used to perform the t test. Results:The evaluation results show that the average scores of theoretical tests (90.12±0.94), cases analysis (9.30±0.10) and physical examination (93.50±0.72) in the experimental group are higher than those of the control group, (83.20±1.66), (8.10±0.11), (85.00±1.75), respectively, with statistical significance ( P<0.05). All 112 questionnaires were collected, with an effective rate of 100%. The percentage of "yes" respondents is as follows, 91.1% of "Enhancing the mastery and application of knowledge"; 97.3% of "Cultivating clinical thinking"; 87.5% of "Improving doctor-patient communication skills"; however, there are 93.8% students believe that this new teaching approach takes more time to prepare before class, consequently, their initiative and enthusiasm of study and learning interest have slid into decline, with percentage of 80.4% and 83.0%, respectively. Conclusion:The teaching method of situational simulation and video feedback in cardiopulmonary and abdominal clinical probation of diagnostics is beneficial to enhance students' understanding and mastery of theoretical knowledge, standardize physical examinations, cultivate clinical thinking ability and improve the doctor-patient communication skills. However, it takes a lot of time for students to prepare before class. If they fail to make reasonable arrangements, the teaching effect will be half the effort and students' initiative and enthusiasm of learning will be reduced.
