Abstract: Objective To explore the effects of "Trinity" case deductive group model training on improving the emergency ability of new nurses,in order to provide reference for relieving the impact of transition of new nurses and fastening adaptation to clinical practice. Methods Seventy-two nurses who met the criteria in the second year of standardized induction training were selected as the research objects,and were successively included into the experimental group and the control group according to the order of entry form,with 36 nurses in each group. Both groups received one set of emergency project-themed training each quarter of a one-year cycle. The experimental group was trained in the trinity of "training needs of participants-clinical needs-training teacher's expertise" case deductive group training,the control group received conventional workshop training. After the training,the scores of theoretical knowledge and skills,and evaluations of training teachers and trainees were compared between the two groups. Results The scores of case analysis and nursing assessment ability in the theoretical and skill assessment of the experimental group were respectively （16.18± 2.07） and （19.24± 1.44）,compared with the control group （14.34± 2.04） and （17.66± 1.84）,the differences were statistically significant （P< 0.05）. The excellent rate of skill assessment in the experimental group was 80.56%,which was 13.89% higher than the control group. The experimental group all thought that the extrapolated scene was real and could stimulate their deep thinking. The improvement of self-emergency ability and feedback of training teachers were better than those of the control group,and the differences were statistically significant（P< 0.01）. Conclusion The “Trinity” case deductive clinical emer-gency response ability training can effectively improve the new nurses' mastery of the training content,and improve their emergency response ability and psychological state in response to sudden changes of clinical conditions.
