Abstract: Objective To develop and implement a competency training program for nursing assistants aimed at comprehensively enhancing their theoretical knowledge,practical skills,and core competencies,and to evaluate the effectiveness of the training. Methods From September to November 2023,60 nursing assistants from 37 medical institutions participating in the Guangdong Province medical nursing professional skills competition were selected as training objects,and the training was carried out based on the conceive-design-implement-operate（CDIO） teaching model. The theoretical scores,skill operation scores and core competence scores of the trainees were compared before and one week after the training,and the satisfaction of the trainees with the training and teaching was investigated by questionnaire survey. Results After training,the theoretical test score of nursing assistants was（84.41±3.35）points,which was higher than before training[（74.68±4.71）points,t=13.674,P<0.05]. The score of skill operation test was （50.30±10.21）points,which was higher than before training[（43.29±9.01）points,t=24.077,P<0.05]. The total score of core competence was （206.53±13.90）points,which was higher than before training[（174.23±10.03）points,t=28.370,P<0.05]. Among them,the score of theoretical knowledge was （39.73±2.83）points,practical skills was （78.10±5.97）points,comprehensive ability was （41.30±3.67）points,human trait score was （47.40±4.57）points,which were all higher after training than before training（t=6.746,14.083,2.101,8.376,all P<0.05）. The overall satisfaction of the trainees was 97.02%. Conclusion The competency training program for nursing assistants,based on the CDIO model,has enhanced the trainees' theoretical knowledge,practical skills,and core competencies. It promotes the continuous growth of nursing assistants and has significant implementation value and potential for broader application.
