Objective:To investigate the application effects of SBAR communication mode (situation, background, assessment and recommendation) combined with 3D printing model technology in bed-side teaching of trauma orthopaedics.Methods:A total of 80 clinical medicine students were randomly divided into two groups according to the order of the school number, with 40 students in each group. One was experimental group which received SBAR communication mode combined with 3D printing model technology teaching, and the other one was the control group, which received regular reaching mode. At the end of teaching, the teaching effects were evaluated, including the scores of theoretical examinations and operational examinations, total scores and the anonymous questionnaires. SPSS 22.0 was used for recording and statistical analysis.Results:The average scores of theoretical examinations (48.30±1.41), operational examinations (42.20±1.48) and total scores (90.70±1.38) of experimental group were significantly higher than those of control group [(43.40±1.52); (34.80±1.53); (78.10±1.51)], with significant differences ( P <0.05). The anonymous questionnaires showed that the students in the experimental group had a significant advantage in autonomous learning ability, learning enthusiasm, the ability of literature retrieval and analysis and clinical thinking ability, and enhancing students' humanistic care consciousness in clinical work ( P <0.05). While the two groups had the same recognition in improving problem solving ability, teamwork ability and communication ability with patients, with no significant difference ( P > 0.05). Conclusion:The new teaching mode, SBAR mode combined with 3D printing model technology, applied to trauma orthopaedics bed-side teaching is helpful for students to improve their learning interest and autonomous learning ability, cultivate their lifelong learning habits and their comprehensive quality, so this mode will significantly improve the teaching effects, with good application value.
