Objective To explore the effects of using standardized patients(SP)to clinical practicing teaching in traumato-osteology. Methods The records of theory exam, case aggregate analysis ability and clinical technical skills of the SP teaching group (SP group) and traditional teaching group(T group) were compared. Results The records of theory exam of the two groups had no significant difference (86.5 ±9.5 VS 82.3 ± 11.7,P>0.05). However, the case aggregate analysis ability of SP group (78.3 ±9.7) was obviously higher than that in control group (65.3 ±7.7), and the records of clinical technical skills of SP group were not significantly higher than control group (85.6 ±9.4 VS72.4 ± 11.6,P>0.05) . More of the students were generally satisfied with SP teaching model. Conclusion The using of SP acted by teachers is helpful to enhancing the clinical skills and thinking and maybe a considerable assisting teaching method in traumato-osteology.
