Abstract: Objective To explore the effect of temporary tutorial system in the teaching of ultrasound medicine for non-ultrasound residents on short-term rotation. Methods Sixty-seven non-ultrasound residents rotating to Department of Ultrasound Medicine, Second Affiliated Hospital of the Army Military Medical University from February 2021 to March 2022 were selected, the 33 residents who rotated from September 2021 to March 2022 were set as the test group, the 34 residents who rotated from February 2021 to August 2021 were set as the control group. The research group was taught by temporary instructors on this basis. The control group was taught by traditional training. Both groups underwent theoretical and practical skills assessment and 360° evaluation at the end of the rotation. Statistical analysis of score difference between groups by t-test. Results After training, the theoretical scores, skill operation scores and film reading diagnosis scores of the students in the test group were (84.48±8.50), (79.42±4.91) and (85.20±6.08) respectively, which were higher than those in the control group (77.02±9.53), (75.20±5.72) and (72.39±7.08), all P<0.05.The results of the 360° evaluation showed that the faculty leading the test group were higher than the control group in terms of teaching enthusiasm [(4.20±0.72) vs. (3.09±0.76)] and teaching time investment [(4.55±0.56) vs. (3.18±0.63)], all P<0.05; The residents in the test group had higher medical knowledge, system-based working ability, and practice-based learning and improvement than the control group[(4.38±0.55) vs. (3.24±0.93), (4.21±0.76) vs.(3.21±0.81), (3.70±0.62) vs.(3.21±1.16)], all P<0.05. Conclusions The application of temporary mentorship during short-term rotations for residents in non-ultrasound specialties helps to acquire needed expertise in ultrasound more quickly and improves the understanding of ultrasound diagnostic thinking and clinical skills and enhances the teaching effect.
