Methods: A questionnaire survey was conducted among 357 nurses from 46 tumor chemotherapy departments in 14 tertiary hospitals in Beijing by convenience sampling. The survey tools were self-designed general data questionnaire and anti-tumor drug infusion set selection knowledge, confidence and practice questionnaire. Results: Among 357 nurses, the knowledge score was 2 (1, 3), with a scoring rate of 37.48%. Totally 166 nurses (46.50%) believed that the selection of infusion set should be carried out by nurses. Attitude: The recognition score was 40 (37, 40) points, the score rate was 94.68%. The overall attitude was positive. Practical behavior: The practical score was 25 (9, 30) points, the score rate was 82.33%. Totally 20 nurses (5.60%) never or rarely paid attention to infusion set knowledge and information related to chemotherapy drugs; Only 142 nurses (39.78%) regularly received infusion set related training. Conclusion: The knowledge level of anti-tumor drug infusion set selection of nurses needs to be improved, the importance of anti-tumor drug infusion set selection attitude is positive, and the practice behavior needs to be strengthened.
