Objective To explore the application effect of teacher feedback combined with peer feedback based on Collaborative Learning in Practice (CLIP) model in the training of trauma care skills for trauma nurses. Methods The trauma nurses were divided into two groups chronologically, the 514 nurses who participated in the China Trauma Care Training-Nursing (CTCT-N) training from June to September 2023 were assigned to a control group, the other 510 nurses who participated the training from July to October were regarded as an experimental group. The control group was routinely trained in the trauma care skills, while the experimental group was trained by utilizing teacher feedback combined with peer feedback based on CLIP model. After the training, the two groups were assessed on trauma care knowledge, the nurses in the experimental group were also assessed on their skills of trauma emergency teamwork, and 28 of them were additionally interviewed to further understand the application effect. Results The experimental group scored significantly higher than that of the control group in trauma care knowledge (P<0.05); the expe-rimental group scored 85.41±8.68 in skills of trauma emergency teamwork;according to the results of the interviews, the trainees felt the training was innovative, they had mastered team collaboration process, and the team collaborated smoothly, but they experienced heavy training stress. Conclusion The combination of teacher feedback and peer feedback based on CLIP model can improve trauma care knowledge of trauma nurses, so as to master team collaboration skills better.
