Abstract: Objective To evaluate standardized training simulation examination for residents trainees in ultrasound medicine. Methods From 2018 to 2020, all the 17 resident trainees participated in the training at the standardized training base for residents located in the department of ultrasound medicine of China-Japan Friendship Hospital.The examination was conducted in stages for capacity building for clinical reasoning, the equipment operation and humanity, three rounds.The assessment performance was analyzed in groups based on academic degree and grade respectively. Questionnaire survey was implemented for trainees' subjective evaluation for simulation examination. Results Both clinical reasoning and the ultrasonic operation dealing with heart check by the graduate group and the undergraduate group showed a progressing trend for three grades, and the postgraduate group had higher performance than the undergraduate group {[clinical reasoning (342.10±26.73) points vs (269.55±30.35) points, (336.00±22.58) points vs (287.18±22.18) points, (352.00±31.00) points vs (327.27±22.31) points], [untrasonic operation for heart check (89.67±7.59) points vs (62.00±2.00) points, (83.00±7.79) points vs(67.50±7.50) points, (97.33±2.05) points vs (89.50±2.50) points]}. There was no statistically significant difference among grades. Performance was evident between grades 1 and 3 with the machine operation [(243.19±18.39) points vs (268.00±25.06) points]. In the undergraduate group, the 1st and 3rd examination progressed significantly [(234.59±15.24) points vs (262.00±33.34) points]. The questionnaire showed that 17 trainees believed that the simulation examination effectively improved their ultrasound skills. Conclusions The simulation examination can improve the clinical skill and increase trainees' confidence, so this method should be shared by other institutions for standardized residents training.
